    There are a lot of benefits to staying physically fit. You’ll have more energy, you’ll look great, and you’ll notice improvements in your health. 1. However, if you focus on exercise, you can make a lot of healthy physical changes.

Find the time. Exercise is one of the most important aspects in staying (or becoming) fit and healthy. 2. Try scheduling your exercise the same way that you schedule other appointments and work. You’ll be more likely to stick to it if it’s on the calendar (日历).

3. You will see the most benefits from exercise if you do it regularly. One good way to make you stick to it is to pick a form of exercise that you enjoy. For example, if you like swimming, make it a point to swim twice a week.

Go outdoors. It is really good to work out at a gym—without air conditioning and televisions. But scientists report that exercising outdoors, at least part of the time, can have more benefits. 4.

Be social. If you join other people in your exercise routine, you’ll see a positive influence in your results. 5. If you schedule an activity with a friend, you are less likely to cancel than if you were only cancelling on yourself.

A.Make it a habit.

B.Enjoy your exercise.

C.Unfortunately, it’s not always easy to stay in great shape.

D.In a word, it is absolutely good for you to stay physically fit.

E.Finding a workout partner can help you to stick to your exercise.

F.The road or sidewalk challenges your body in ways that gyms can’t do.

G.Experts recommend that you should be active for at least 30 minutes per day.

    Genetic modification (基因改良) dates back to ancient times, when humans influenced genetics by selectively breeding organisms (培育生物) according to an article by Gabriel Rangel, a public health scientist at Harvard University. When repeated over several generations, this process leads to great changes in the organisms.

Dogs were likely the first animals to be purposefully genetically modified, with the beginnings of that effort dating back about 32,000 years, according to Rangel. Wild wolves joined our hunter-gatherer ancestors in East Asia, where the aggressive canines were kept in the household and bred to become docile and easier to get along with. Over thousands of years, people bred dogs with different desired character and physical characteristics, eventually leading to the wide variety of dogs we see today.

The earliest known genetically modified plant is wheat. This valuable crop is thought to have originated in the Middle East and northern Africa in the area known as the Fertile Crescent, according to a 2015 article published in the Journal of Traditional and Complementary Medicine. Ancient farmers selectively bred wheat grasses beginning around 9000 B. C. to create improved varieties with larger grains and hardier seeds. By 800 B.C., the cultivation (培养) of improved wheat had spread across Europe and Asia. The continued selective cultivation of wheat resulted in the thousands of varieties that are grown today.

Corn has also experienced some of greatest genetic changes over the past few thousand years. The main crop was changed from a plant known as teosinte, a wild grass with tiny ears and only a few seeds. Over time, farmers selectively bred the teosinte grasses to create corn with large ears bursting with seeds.

Beyond those crops, many of the fruit and vegetables we eat today, including bananas, apples and tomatoes, have experienced several generations of selective raising, according to Rangel.

In 1973, researchers also modified bacteria to be used as drugs. In 1982, human insulin (胰岛素) made from genetically engineered bacteria, became the first genetically engineered human drugs approved by the FDA.

1.What does the word “docile” in paragraph 2 most probably mean?

A.Gentle. B.Loyal. C.Smart. D.Ambitious.

2.How did the ancient farmers try to improve wheat?

A.Through selective cultivation. B.By editing its genes constantly.

C.Through mixture with teosinte. D.By planting it in large numbers.

3.What can we infer about genetic modification?

A.It is rarely seen in daily life. B.It was quite difficult to accept.

C.It is hardly influenced by humans. D.It played a role in medical field.

4.From which section of a newspaper is the text most probably taken?

A.Health. B.Lifestyle. C.Science. D.Agriculture.

    When my 8-month-old cries, I ask him if he’s hungry, or wet or just needs a hug.

“Babububuu,” he says.

What I need is a baby cry translator. That’s just what a team of researchers say they’ve developed.

“Experienced nurses or pediatricians (儿科医师) can identify why baby is crying because they have experience, says Lichuan Liu, a professor of electrical engineering at Northern Illinois University, who conducted the research.” We talked to them, and they mentioned that based on the cry’s’ sound there’re’ some clues (线索).”

So Liu set out to identify the features of cries that can help mark them as expressions of pain or discomfort. These features include differences in pitch (音高) and frequency. The team then developed an algorithm (算法) based on automatic speech recognition to detect and identify these features. This “cry language recognition algorithm” was trained on recordings of baby cries taken from a hospital. It uses compressed sensing, a process that reconstructs a signal based on incomplete data. It can identify a baby cry against a background of, say, adult speech or loud television sounds. By classifying different cry features, like pitch, the algorithm can suggest whether the cry is due to sickness or pain, and identify the degree of urgency.

The team had experienced pediatric care providers assess forty-eight baby cry recordings for probable cause of crying hunger, tiredness, etc. They then compared these to the algorithm’s assessments. The algorithm agreed with the humans 70% of the time. Generally, so-called “uncommon cry signals”—signs of pain or sickness—are high-pitched and very loud compared to ordinary crying.

Liu and her team continue to train the technology for greater accuracy. They also plan to add more features, like the ability to identify and classify movement and facial expressions. This could help give more detailed reading of baby’s emotional (情感的) and physical state. They also hope to begin human trials in the near future.

1.The author mentions the 8-month-old child to ________.

A.draw attention to baby cries B.prove baby cries are common

C.lead in a translator for baby cries D.show the use of cry translators

2.What inspired Lichuan Liu’s idea of doing the study?

A.Pediatric care workers’ words. B.The pediatricians’ strong requests.

C.Her own nursing experiences. D.Her doubts about the previous research.

3.What did the researchers do in the study?

A.They collected baby cries from big hospitals.

B.They got 48 baby cry recordings evaluated.

C.They created an automatic speech recognition.

D.They analyzed cry features with compressed sensing.

4.What can we know about Liu’s cry language recognition algorithm?

A.It has been widely used in daily life.

B.It’s mainly meant for hungry cry signals.

C.It has been proved effective on babies.

D.It’s only been tested on recorded cries now.

    After a Blockbuster store in Australia closes on March 31, the American city of Bend, Oregon will have the only one left on Earth.

For years, Blockbuster was a big name in the video rental business. The company had thousands of stores in the United States and around the world. But Blockbuster began to lose money during the 2000s. By 2014, all company-owned stores had closed. Since then, locally owned Blockbusters have closed, one by one.

Operating the last Blockbuster Video on Earth is not easy. The computer system uses old disks that only the store’s general manager knows how to use. The video rentals are recorded on a kind of aging tape. The tape cannot be replaced because Radio Shack, another once famous store, went out of business.

Sandi Harding has worked at the Blockbuster in Bend for over 15 years and is the store’s general manager. She says “stubbornness” is part of the reason the store is still open. “We did everything we could to cut costs and keep ourselves relevant,” she said.

Zeke Kamm lives in Bend. He is making a documentary about the store with his friend. He notes that many people who rented videos over the years want to share memories of their experiences Kamm explained how Blockbuste were once an important part of small town in America. The Blockbuster was the only place that was open past nine at night, and a lot of them stayed open much later.

Recently, Harding has noticed that more children are coming to the store, brought in by their parents who like remembering the past. Jerry Gilless and his wife, Elizabeth, on a trip to Oregon, recently brought their two children, aged 3 and 5, to the store in Bend. They watched with a smile as their children walked from row to row, looking at movies. “How could we not stop? It’s the last one,” said Gilless. “They need to see that not everything’s on the iPad.”

1.What is the third paragraph mainly about?

A.The popularity of the video rental business. B.The special computer system of the last store.

C.The value of the last Blockbuster on Earth. D.The difficulties of running the last Blockbuster.

2.Why is the Blockbuster store in Bend still open?

A.It has a long history in all Blockbuster stores. B.Its employees try their best to keep it running

C.Its general manager is very stubborn woman. D.It is a place where people can watch old movies.

3.What is the documentary of Zeke Kamm probably about?

A.People’s experiences of sharing their own memories.

B.Zeke Kamm’s work with his friend in the Blockbuster.

C.People’s memories of renting videos in the Blockbuster.

D.Blockbusters’important role in a small town of America.

4.What’s the best title for the text?

A.Oregon Will Have the Last Blockbuster on Earth B.Different Opinions About the Last Blockbuster

C.People Are Interested in the Last Blockbuster D.A Documentary About the Last Blockbuster
