I used to be a person who hates exercising. But after I started playing baseball, I attracted by the sport. Therefore, I cut down on most of my spare time, like shopping. Though it wasn’t the hard process for me, I needed to make more of an effort than others. I enjoy the feeling of work with my teammates as well as the time we spend it together. There is a proverb that goes, “The process is much beautiful than the outcome.”

I am a beginner in this sport. Sometimes people will look down on me, and it doesn’t matter. It will only make me keep trying. Only with practising over and over again do I believe I can catch up with other fantastic player one day. The challenge encourages myself to go on.

Zhou Shihao, 17, from Shanghai Yichuan High School, was shocked by the statistics he had found. 1. he was looking into the use of handheld cellphones by drivers, he found that more than 30% of them reached for their phones on the road.

“Any use of handheld devices(设备) should 2.(firm)be forbidden while driving,” said Zhou. “It’s not a daily chore, but a serious social issue.”

The teenager’s concerns led to his drafting a proposal on this issue – something 3. he did together with five other schoolmates in the Mock Chinese People’s Political Consultative Conference competition in the Putuo District of Shanghai.

Zhou and his schoolmates were not alone. In January, many Shanghai youngsters, even elementary school students, took part in Mock CPPCC competitions 4.(hold) in their local districts and handed in proposals on issues ranging from network security and the future city to the protection of 5.(tradition) culture.

“The competition really encourages us students to focus on social issues and play an active role 6. taking responsibility for our country,” said Zhang Simin, 17, from Shanghai Nanyang High School.

The senior student used to think that the handling of state affairs was just for politicians. But thinking on the “3:30 problem” changed her mind.

Kids usually finish school at 3:30. However, most parents work until 6:00, 7.(make) it hard for them to pick kids up. “This is a problem we’ve all been through,” said Zhang.

To help students, Zhang’s school 8.(invite) deputies (代表) to the National People’s Congress to give students instruction.

“Thanks to the deputies, we finally understand it’s not who is to blame that 9.(matter), but finding the best solution,” said Zhang.

“The competition aims to encourage a sense of citizenship among China’s post-00s generation,” said Xia Jing, a teacher from Shanghai Jinyuan Senior High School. “Through this channel, students can let their 10.(voice) be heard.”

    Word travels quickly in the small fishing village of Port Washington, Wisconsin. So when Mardy McGarry wanted to build a playground for kids with special needs, she knew it wouldn’t take long to create interest in the project. But she never expected that a third of the town people would join in it. 1.

“A lot of learning comes through play,” says McGarry, a special education teacher for 28 years. She’d seen the wood chips and sand of traditional playgrounds stop wheelchairs dead in their tracks.

When a piece of land became available, the city council agreed to choose a part for a playground. 2. She asked classrooms of kids for their wish list. She also asked experts for help. And she brought on board her friend Sue Mayer, whose eight-year-old son, Sam, has a serious disease.

Her Kiwanis Club chapter came through with $ 7,000, and that’s when the grassroots movement really got started. One woman gave $ 25,000 and had her company donate the same amount. 3. There were silent auctions(拍卖) and T-shirt sales. The local Pieper Family Foundation offered to donate half of the remaining $170,000 balance if McGarry could raise the rest. The $ 450,000 covered materials, but the actual construction would cost an additional $ 900,000. Not a choice. But the community could build it.

On September 16, 2008, the first day of construction, they came. Two women heard about the project on the radio on the way to work and took the day off to help. 4. Ten-year-olds sanded surfaces.

Today, Possibility Playground is one of the most popular destinations in Ozaukee County. There’s a giant pirate ship, a rock-climbing wall, high and low rings, monkey bars, sandboxes, swings, slides, bridges and so on.

5. It’s exactly what McGarry wanted. People used to ask why she wanted to build a playground just for children with disabilities. “They didn’t get it. It’s only when you build a playground for children with disabilities that you build one for all children,” she said.

A. Soon smaller businesses were helping.

B. All children play shoulder to shoulder.

C. But her students were too often left out.

D. Everyone thought it was really a great wonder.

E. A couple in their 80s operated their own trucks.

F. McGarry started researching play equipment and contacting design firms.

G. They rolled up their sleeves and used their weekdays to bring her idea to life.

    Scientists think that growing garden grass could be the secret to solving our energy needs, and we may soon be able to replace our gasoline with “grassoline”.

The team, including experts from Cardiff University in Wales, has shown that hydrogen can be taken from grass in useful amounts with the help of sunlight and a cheap catalyst(催化剂) —something that speeds up a chemical reaction without being used up.

It is the first time that this has been shown and it could lead to a sustainable(可持续的) way of making hydrogen, reported Asian News International. This could be an important kind of renewable energy because it is high in energy and it does not give out harmful gases when it is burned.

Study co-author Michael Bowker said, “This is really a green source of energy. Hydrogen is seen as an important future energy carrier as the world moves from fossil fuels to renewable energy, and our research has shown that even garden grass could be a good way of getting it.”

Cellulose(纤维素), which is a key part of plants and the biopolymer(生物聚合物) found in the largest numbers on the earth, could be a great source of hydrogen.

In its study, the team looked at the possibility of getting hydrogen from cellulose using sunlight and a simple catalyst.

This is called photocatalysis(光催化作用) and in it, the sunlight starts the catalyst, which then makes cellulose and water into hydrogen. The researchers studied the effectiveness of three metal-based catalysts, of which nickel(镍) especially interested the researchers, as it is a much more common metal than gold and palladium(钯) and it saves more money.

According to Bowker, producing hydrogen from cellulose using photocatalysis has not been studied in detail. The team’s research shows that large amounts of hydrogen can be produced using this method with the help of a bit of sunlight and a cheap catalyst.

The study shows that it is effective to use real grass taken from a garden. “This is important as it avoids the need to separate and clean up cellulose, which can be both difficult and costly,” said Bowker.

1.What are needed to get hydrogen from grass?

A. A catalyst and palladium. B. Water and cellulose.

C. Sunlight and a biopolymer. D. Sunlight and a catalyst.

2.Why is the new way of making hydrogen considered significant?

A. It is cheap, green and sustainable.

B. It is the best to produce the renewable energy.

C. It is more productive and efficient than other methods.

D. It can replace the way to make fossil fuels completely.

3.Why does nickel interest the researchers in making hydrogen from cellulose?

A. It can produce the largest amount of hydrogen.

B. It can avoid separating and cleaning up cellulose.

C. It is more common than other metals and costs less.

D. It works quicker than other metals during photocatalysis.

4.What does the author intend to tell us mainly in this passage?

A. Catalysts that could be taken from grass.

B. A new way of making hydrogen from cellulose.

C. The potential of hydrogen as a renewable energy.

D. The connection between hydrogen and photocatalysis.

    People have different ways of dealing with a common cold. Some take over-the- counter(非处方的) medicines such as aspirin while others try popular home remedies(治疗)like herbal tea or chicken soup. Yet here is the tough truth about the common cold: nothing really cures it.

So why do people sometimes believe that their remedies work? According to James Taylor, professor at the University of Washington, colds usually go away on their own in about a week, improving a little each day after symptoms peak, so it’s easy to believe it’s medicine rather than time that deserves the credit, USA Today reported.

It still seems hard to believe that we can deal with more serious diseases yet are powerless against something so common as a cold. Recently, scientists came closer to figuring out why. To understand it, you first need to know how antiviral(抗病毒的) drugs work. They attack the virus by attaching to and changing the surface structures of the virus. To do that, the drug must fit and lock into the virus like the right piece of a jigsaw(拼图), which means scientists have to identify the virus and build a 3-D model to study its surface before they can design an antiviral drug that is effective enough.

The two cold viruses that scientists had long known about were rhinovirus(鼻病毒) A and B. But they didn’t find out about the existence of a third virus, rhinovirus C, until 2006. All three of them contribute to the common cold, but drugs that work well against rhinovirus A and B have little effect when used against C.

“This explains most of the previous failures of drug trials against rhinovirus,” study leader Professor Ann Palmenberg at University of Wisconsin-Madison, US, told Science Daily.

Now, more than 10 years after the discovery of rhinovirus C, scientists have finally built a highly-detailed 3-D model of the virus, showing that the surface of the virus is, as expected, different from that of other cold viruses.

With the model in hand, hopefully a real cure for a common cold is on its way. Soon, we may no longer have to waste our money on medicines that don’t really work.

1.What does the author think of popular remedies for a common cold?

A. They are quite effective.

B. They are slightly helpful.

C. They actually have no effect.

D. They still need to be improved.

2.How do antiviral drugs work?

A. By breaking up cold viruses directly.

B. By changing the surface structures of the cold viruses.

C. By preventing colds from developing into serious diseases.

D. By absorbing different kinds of cold viruses at the same time.

3.What can we infer from the passage?

A. The surface of cold viruses looks quite similar.

B. Scientists have already found a cure for the common cold.

C. Scientists were not aware of the existence of rhinovirus C until recently.

D. Knowing the structure of cold viruses is the key to developing an effective cure.

4.What is the best title for this passage?

A. Drugs against cold viruses B. Helpful home remedies

C. No current cure for common cold D. Research on cold viruses

    Thomas Cheatham had planned to study Latin during his time at Hebron High School in Texas. But when he learned that the school district was going to offer a Mandarin(普通话) class, he quickly changed his mind.

“I thought Mandarin would be more beneficial than Latin,” said Cheatham, who is now in his second year of studying the language.

He speaks Mandarin to order food at Chinese restaurants and can read social media posts from his Chinese-speaking friends. While it’s a difficult language to master, the high school junior, who plans to study computer engineering, thinks it will be important for his career. “Chinese is a good language to know, especially with China becoming a growing power,” he said.

Many experts agree that proficiency(熟练) in a language spoken by a billion people worldwide will give American students an edge in the global economy.

“People are looking at China as our next economic competitor, and interest in Mandarin is growing fast,” said Marty Abbott, director of the American Council(议会) on the Teaching of Foreign Languages. “We’re seeing it in all parts of the country.”

Abbott predicts that as many as 100,000 students are now studying Mandarin in public and private schools throughout the US. She said the US government has designated (指定) Mandarin as an “important needs” language and provides professional development programs for teachers. “Our government wants to increase our language ability for national security and economic competitiveness,” Abbott added.

At the same time, the Chinese government is spreading knowledge of the Chinese language and culture through Confucius Institutes set up in many US states. For example, the Confucius Institute at the University of Texas in Dallas has been the home of a Confucius Institute for 10 years. It sponsors Confucius Classrooms at 21 local public and private schools, where tens of thousands of students are learning Mandarin.

1.Why did Thomas Cheatham decide to study Mandarin instead of Latin?

A. Mandarin was easier to learn than Latin.

B. Mandarin could be helpful to his future career.

C. Mandarin might help him learn more about China.

D. Mandarin could enable him to study computer engineering.

2.The underlined word “edge” in Paragraph 4 probably means “________”.

A. a slight advantage B. the outside limit

C. a sharp tone of voice D. an exciting quality

3.Which of the following statements might Marty Abbott agree with?

A. Mandarin should be taught in classrooms throughout the US.

B. Those skilled at Chinese will be the most competitive in the future.

C. The US government’s policy has helped popularize Mandarin in the US.

D. Americans learn Mandarin because they worry about their national security.

4.What does the author mainly talk about in this passage?

A. The rising popularity of Mandarin among American students.

B. The great benefits of learning Mandarin for American students.

C. The influence of China’s growing power on American education.

D. The effect of Confucius Institutes in promoting Mandarin in the US.

Rise and shine all day

Making these easy tasks part of your morning schedule will improve your nutrition, energy, and mood today—and beyond.

Stretch in bed

Try this even before you open your eyes. Lift one arm and begin by stretching each finger, then your hand, then your wrist, and then your whole arm. 1.. Then stretch your toes, feet, ankles, and legs. Finally, end with a neck and back stretch that pushes you out of bed. This “power pose” makes you feel more confident all day long.

2.

Working out before you eat encourages your body to burn more fat for energy rather than relying on carbohydrates（碳水化合物）from food. In a study, participants who exercised after breakfast still gained weight, but those who exercised on an empty stomach did not.

Turn on the music

3.. If anyone plays an instrument, and if you have a little time, morning is the perfect time to practice, as it prepares your brain for learning. One study found that both playing and listening to music help improve academic performance in 16 different ways, including increasing focus and memory.

Enjoy some fun

Many people fear to face a new day of work, school, or chores.4.. This can be having a cup of coffee as you read your favorite blog, etc. Choose activities you enjoy and that set you on a good path for the day

You’ve improved your state of mind, your health, and your productivity—all before the weekday has even begun.

5..

A. Pick something energetic that you and others in the house enjoy and put it on while you get ready

B. Now you’re ready to conquer your to-do list for today and every day

C. Do regular exercise in the morning

D. Move on to the other arm

E. Exercise a bit—On an empty stomach

F. Take up the entire length of the bed when you stretch

G. But if the first thing you do is pleasant, you’ll find it much easier to get going

    You’ve got your fancy new suitcase and you’re ready to take it with you on your travels across the globe.

You get to the airport, quickly moving through the crowds on the uneven pavement, rushing to check in. Then, your heart sinks when you realize your new suitcase has got a serious case of the wobbles (摇晃).

Why does this happen?

Scientists from the Universite Paris-Diderot in France investigated this matter and published their findings in the science journal Proceedings of the Royal Society A. They also suggested some solutions to overcome this modern-day problem.

To learn more about the issue, they put a suitcase on a treadmill (跑步机) and observed what happened.

It was soon noted that the “wobble” was actually a result of repeated actions that caused the suitcase to sway from side to side. They discovered that if one of the wheels encountered an obstacle such as a small bump, it jumped into the air for just a moment and then banged back down to the ground. That second action caused the opposite wheel to lift off the ground and then to bang back down, causing the first to lift again and so on. This swaying increased as the luggage was pulled along.

“The suitcase is a fun way to tackle the problem, but the study would be the same for any trolley with two wheels or blades (桨叶),” Sylvain Courrech du Pont, lead author of the study, told BBC News. “So it will be the same for a caravan (大篷车) or maybe also for airplanes.”

Instead of slowing down when we see a rocky part of the path, the scientists recommended doing the exact opposite and speeding up. This is because going faster gives the wheels less time to rise and fall, preventing the case from swaying. They also said that reducing the angle of the suitcase by lowering its handle to the ground would help keep it steady.

“These findings could help researchers simulate and design better rolling suitcases and other pulled trolleys, such as towed trailers ,” Courrech du Pont added.

With these masterminds (智者) working on perfecting our suitcase problems, wobbly luggage may soon be a thing of history, leaving us to enjoy our travels.

1.The main purpose of the first two paragraphs is to ______.

A. show the importance of a good wheeled suitcase for travel

B. lead up to the wobbling problem of wheeled suitcases

C. describe how unstable wheeled suitcases can be

D. show that wobbling can cause wheeled suitcases to stop working

2.According to the scientists, when a suitcase meets with an obstacle, ______.

A. the swaying will stop for a moment

B. its two wheels will jump into the air at the same time

C. even a small obstacle can lead to a serious damage

D. there is a series of repeated actions leading to the swaying

3.What can be done to keep a suitcase steady on an uneven path according to the text?

A. Slow down. B. Pull the suitcase at a faster speed.

    When Huang Lizhi took her first class in African sociology at the University of the Witwatersrand in South Africa in February, her professor asked her and her classmates what impresses them most when it comes to Africa.

Unexpectedly, Huang, 31, found that words like “poverty” and “safari” – negative words that were often associated with the continent in media reports – were the kind of terms her African classmates didn’t want to hear. Instead, they preferred to hear the question answered in this way: “Africa is the cradle of humankind” and “Africans are passionate and generous”.

Apparently, there are some misunderstandings between us. It’s true that with incidents like the Ebola outbreak in Western Africa and the emergence (出现) of pirates off the coast of Somalia hitting the news, it’s easy for us to keep forgetting that Africa has one of the world’s oldest civilizations – Egypt, born by the world’s longest river, the Nile. The proof is in the Great Pyramid of Giza and the Great Sphinx of Giza, which are both popular among tourists. And the tombs of ancient Egypt have also become endless sources for the literature and film industries.

When it comes to the natural environment of Africa, our misunderstandings are only bigger. But the truth is that instead of being extremely hot all year and covered by desert, the continent has large areas of savannas (稀树草原) where lions, giraffes and zebras live, the snowcapped Kilimanjaro – the highest mountain in Africa – and even thick forest on the island of Madagascar.These misunderstandings are one of the reasons why the 2018 Beijing Summit of the Forum on China-Africa Cooperation was held on Sept 3 and 4 – to understand each other better.

Indeed, only by visiting Africa herself did Huang see the convenient living conditions, the amazing natural beauty and the friendly people.In her eyes, her classmates were as hopeful about the future of their own countries as they were about Africa as a whole, and they were quick to demonstrate both their strong will and activity. “At that moment, I knew exactly what they wanted – they wanted their culture to be respected.”

1.Which of the following best explains “cradle ” underlined in paragraph 2?

A. A small bed for babies.

B. A basket to hold something.

C. A place for people to relax themselves.

D. A place where something important began.

2.What can we infer about Africa according to the passage ?

A. It is very hot all the year round. B. It’s not a safe continent to live in

C. It’s different from what we imagine. D. It is bound to have a bright future

3.Which of the following would Huang agree with ?

A. To see is to believe B. Think twice before you do

C. A miss is as good as a mile D. Don’t judge a person by his appearance

4.What can be a suitable title for the text?

A. Valuing a Culture. B. Understanding Africa.

C. Paying a Visit to Africa. D. Discovering a Continent.

Though you shouldn't be afraid to spend the extra money on a memorable gift, it's important to remember that there are more important things.3. The gift is meant to be a reflection of that. In some cases, it can feel even more thoughtful if you make something yourself.

    A new study suggests climate conditions in the Sahara Desert, one of hottest, driest and most deserted areas in the world, have changed from wet to dry a about every 20,000 years.

But previous evidence has suggested the Sahara did not always experience such extreme heat and dry conditions. At times, the Sahara Ranged to a very wet climate. This permitted plants and animals to develop and grow and led to the creation of human settlements. Now, they have discovered more evidence, which, the lead researcher David Mc Gee says, supports the idea that the Sahara's climate kept changing between wet and dry about every 20,000,years.

McGee reported these climate changes were mainly driven by changes in the Earth's(地轴)as the planet travels round the sun .This process affects the amount of sunlight between seasons. Every 20,000 years the Earth receives more strong summer sunlight. When the Earth's axis changes again, the amount of sunlight is reduced. This season change happened continuously every 20,000 years. The other part of the season produced rainy conditions, resulting in a wetter, greener, plant-rich environment. When the rainy activity weakens, the climate becomes hot and dry, like the Sahara remains today.

The scientists based their research on dust collected from ocean sediment(沉积物)in the Atlantic Ocean bottom off the coast of West Africa. The dust contained layers (层)of ancient sediment built up over millions of years. Each layer could contain traces of Saharan dust as well as the remains of life forms. This information was used to assess over what time period the dust had built up. This led to the overall finding that the Saharan changes from wet to dry climates happened every 20,000 years.

David McGee said that today we only see the Sahara Desert as an extremely deserted and “inhospitable” place. The new study suggests that the area's climate has changes between grasslands and a much wetter environment, and back to dry climates, even over the last quarter million years. McGee says he thinks the latest research can be valuable in studying the Sahara's history as it relates to human settlement.

1.What does the new study find about the Sahara Desert?

A. It is one of the hottest, driest and most deserted areas in Africa.

B. It always experiences extreme conditions because of its position.

C. Its climate changes between wet and dry about every 20,000 years.

D. Its environmental conditions stop plants and animals from surviving.

2.What is the direct reason for Sahara's climate changes?

A. Rainy activity. B. Solar radiation.

C. Human activity. D. Global environment.

3.How did the researchers acquire the evidence?

A. By analyzing ocean life.

B. By studying Sahara’s history.

C. By collecting dust on the coast.

D. By examining mean sediment.

4.What does the underlined word “inhospitable” probably mean?

A. Unsuitable to live. B. Insignificant lo study.

C. Unable to explore. D. Impossible to change.

    John George, 60, remembers that he lived a wonderful life in the Detroit neighborhood where he grew up. “We knew all our neighbors.” George told Detroit's Metro Times. “On Christmas Eve, we'd all go to midnight Mass, and there'd be 300 people in our house at one o’clock to about five in the morning. The folks were just really good, hardworking people. ”

By the'80s, however, the old neighborhood changed. Due in part to economic downturns and drug abuse, well -kept homes had been abandoned and kindly neighbors had fled to the suburbs(郊区). But not George. “Living in any city, it’s like being in a relationship,” he told Reader’s Digest. “Some days are better than others. But it was my home. And when I saw it becoming worse, I had two choices: I could leave, or I could stay and fight. I chose the latter.”

When the abandoned home behind his turned into a worn-out place, the father of two grabbed some boards and nails and began boarding up the house. After two neighbors stopped to ask what he was doing, they decided to help, with great results.

That's how it all got started. In the 30 years since that first home rescue, an army of approximately 182,000 volunteers, along with private donors, has helped George pull down around 300 abandoned homes, mainly in die poorer Northwest area of Detroit. They've also secured 400 - some homes by boarding them up. They've painted and repaired nearly 900 homes and built over 100 from scratch. According to Forbes, more than 1,000 Detroiters have been housed as a result of their work.

And there's Halloween. In Detroit, October 30 was known as Devil's Night, a period when all hell break loose in the form of crime and vandalism (破坏公物). In response, George created a citizens' patrol(巡逻)that would take to the streets, keeping an eye on illegal behavior. He named it Angels' Night What began with 12 neighbors on patrol in 1990 has grown to more than 60,000 citywide.

George's inspired ideas have not gone unnoticed by the city he loves. Others are buying into it. There's a trend of younger homeowners coming in.

1.What was George’s home city Detroit like before the ’80s?

A. Neighbors were nice and got along very well.

B. People in the suburbs led a wonderful life.

C. Economy declined because of drug abuse.

D. Many homes were abandoned and people lied.

2.What did George decide to do after his neighborhood changed?

A. Move to the suburbs. B. Leave his hometown.

C. Join his neighbors to help. D. Stay and fight to save his city.

3.What happened as a result of George and other volunteers' hard work?

A. More people moved into Detroit.

B. Almost all Detroiters were housed.

C. Over 100 homes were newly built.

D. There was no illegal behavior any more.

4.What does the story mainly intend to toll us?

A. Great minds think alike.

B. Two heads are better than one.

C. A friend in need is a friend indeed.

D. Little people can make a big difference.

    In the U. S. state of Washington, a road called Interstate(州际公路；州际的)90 cuts through a wild mountainous area to reach the city of Seattle. For the area's many kinds of animals, busy high- way greatly limits their movements. Animals need to move to find food, to find mates, to find new places to live as their populations expand or just when conditions change, like a fire breaks out. Crossing I-90 – as the road is called – is a risky but sometimes necessary act. But soon, animals will have a safer choice. They will be able to go above it.

To help the animals, the state is finishing work on its largest - ever wildlife bridge. The 11-meter-tall, 20 - meter - wide bridge begins in the forest. It forms two arches above the highway, one for each direction of traffic. Workers are adding fencing anti plants to help guide the animals across the bridge，Two-meter-thick walls will help block noise from vehicles below. Scientists chose the area because it is within a natural migration(迁徙)path for some animals.

The I -90 bridge is part of a growing number of wildlife crossings across the United States. Some are fences, some are overland bridges，and some are underpasses. They all aim to keep drivers and animals away from each other.

A U. S. Transportation Department study found crashes between animals and humans rose year by year. The accidents made up about 5 percent of all crashes nationally, and cost the economy (经济)about ＄ 8 billion. Such costs come from car repaid, emergency room visits and removal of the dead animals on roads. Collisions between animals and drivers are rarely deadly to people. But they are often deadly to wildlife. The study also found that 21 endangered or threatened species in the U.S. are affected by vehicle hits. Bridges, underpasses and fencing reduce I he area's animal - driver collisions by 80 percent.

Most of the wildlife bridges are in western states. Many other areas also need such paths. But finding money for more crossings is“the- number - one problem”. Patty Garvey — Darda of the U. S. Forest Service has worked on the I - 90 crossing from the start of the project. She says the $ 6 - million bridge will one day pay for itself because the highway will not have to be fully or partly closed each time a large animal is struck. “If you shut clown Interstate 90, you shut down interstate trade. ” she adds.

1.What do we know about die I -90?

A. It goes from Washington D.C to Seattle,

B. It is dangerous for wild animals to cross.

C. It blocks the movements of wild animals.

D. It is the longest - ever highway in the world.

2.What is being done to help the animals?

A. Building a wildlife bridge to keep drivers and animals away.

B. Designing walls to protect animals from traffic accidents.

C. forming 2 arches, one for traffic and the other for animals.

D. Choosing a natural and safe area for wild animals to live in.

3.What can we learn from the study?

A. Traffic accidents went down gradually nationwide.

B. Most money was spent in rescuing wild animals,

C. Collisions are more deadly to wildlife than to people,

D. Some species no longer existed because of vehicle hits.

4.Which of the statements may Patty Garvey - Darda agree with?

A. The bridge costs too much money.

B. Animals won11 be struck by drivers.

C. The effort to build the bridge will pay off.

D. Collisions won't affect national trade at all.
