Summer is the perfect time to relax. As you plan for your trip, here are some tips on how to protect yourself. 1.

Fight against the mosquitoes in the hot spots.

There are many mosquito-borne illnesses in tropical regions, which are traditionally vacation hot spots. Therefore, mosquito repellent(驱蚊剂)that contains DEET should be an essential item in your travel bag.


In lesser-developed countries there is less equipment for clean water and public health. If you can't avoid unhealthful water, make sure you bring along a tea or coffee—making pot that will boil water for you. You’d better buy a case or two of water and check that all bottle caps are sealed to assure the bottled water isn't just a refilled bottle of dirty tap water.

Always protect your feet.

It's best to wear slippers in the shower, but if you must be barefoot, put a towel down on the floor.3.You should never walk barefoot in any area of a foreign country, including your hotel room.

Be sure to eat safe fruits.

4. They may have been washed in the same water, or wiped with the same rag used to clean work surfaces in kitchens. The best advice is to bring your own peeler(削皮器)so that you know that something clean has been applied to the fruit.

Enjoy the smell of roadside stands, not the food.

Unless the food is piping hot when served, it’s best to stay away from roadside stands, no matter how good the smell of the food might be. If you are concerned about whether a restaurant is clean, order the food to go. 5.

A.Don't trust the local water

B.Any fruit served fresh may be polluted

C.Look out for any water not served in a bottle

D.The boxes may be cleaner than the plate or fork on the table

E.You should know how to keep yourself away from dirty fruits

F.They are necessary to avoid coming back with a major illness from your trip

G.Parasites(寄生虫)can enter the skin of your feet and travel to different parts of the body


    Recently there was a major discovery in the scientific research—the mapping of all DNA in a human gene is complete. Several years ago, it seems an impossible task for scientist to accomplish. All this progress in science leads us to believe that the day when human being will be cloned is not far away. Human cloning has always been a topic of argument in terms of morality (道德) or religion.

Taking a look at why cloning might be beneficial, among many cases, it is arguable that parents who are known to be at risk of passing a genetic limitation to a child could make use of cloning. Moreover, cloning would enable women who can't get pregnant to have children of their own.

Cloning humans would also mean that organs could be cloned, so it would be a source of perfect transfer organs. This surely would be greatly beneficial to millions of unfortunate people around the world who are expected to lose their lives due to organ problems. It is also arguable that a ban on cloning may be unlawful and would rob people of the right to reproduce and limit the freedom of scientists.

However, arguments against cloning are also on a perfectly practical side. Primarily, I believe that cloning would step in the normal "cycle" of life. There would be a large number of same genes, which reduce the chances of evolution, since it may be difficult for living creatures to naturally adapt to the ever-changing environment, which will result in ultimate disappearance. Furthermore, cloning would make the uniqueness that each one of us possesses disappear. Thus, leading to creation of genetically engineered groups of people for specific purposes and, chances are that those individuals would be regarded as "objects" rather than people in the society.

Scientists couldn't surely guarantee that the first cloned humans will be normal. Thus this could result in introduction of additional limitations in the human "gene-pool".

Regarding such arguable topics in "black or white" approach seems very innocent. We should try to look at all "shades" of it. I believe that cloning is only legal if its purpose is for cloning organs; not humans. Then we could regard this as for "saving life" instead of "creating life". It is believed that cloning humans is morally and socially unacceptable.

1.What's the author's opinion on cloning?

A.Cloning should be entirely banned.

B.Cloning should be used in creating life.

C.Cloning will take away the right to reproduce.

D.Cloning is acceptable if it is used for cloning organs.

Getting rid of dirt, in the opinion of most people, is a good thing However, there is nothing fixed about attitudes to dirt.

In the early 16th century, people thought that dirt on the skin was a means to block out disease, as medical opinion had it that washing off dirt with hot water could open up the skin and let ills in. A particular danger was thought to lie in public baths. By 1538, the French king had closed the bath houses in his kingdom. So did the king of England in 1546. Thus began a long time when the rich and the poor in Europe lived with dirt in a friendly way. Henry IV, king of France, was famously dirty. Upon learning that a nobleman had taken a bath, the king ordered that, to avoid the attack of disease, the nobleman should not go out.

Though the belief in the merit(优点) of dirt was long-lived, dirt has no longer been regarded as a nice neighbor ever since the 18th century. Scientifically speaking, cleaning away dirt is good to health. Clean water supply and hand washing are practical means of preventing disease. Yet, it seems that standards of cleanliness have moved beyond science since World War II. Advertisements repeatedly sell the idea: clothes need to be whiter than white, cloths ever softer, surfaces to shine. Has the hate for dirt, however, gone too far?

Attitudes to dirt still differ hugely nowadays. Many first-time parents nervously try to warn their children off touching dirt, which might be responsible for the spread of disease. On the contrary, Mary Ruebush, an American immunologist(免疫学家), encourages children to play in the dirt to build up a strong immune system. And the latter position is gaining some ground.

1.The kings of France and England in the 16th century closed bath houses because         .

A. they lived healthily in a dirty environment

D. They believed disease could be spread in public baths

2.Which of the following best describes Henry IV’s attitude to bathing?

A. Curious    B. Afraid    C. Approving    D. Uninterested

3.How does the passage mainly develop?

A. By following the order of time.    B. By making comparison.

C. By providing examples    D. By following the order of importance.

4.What is the author’s purpose in writing the passages?

A. To call attention to the danger of dirt.

B. To introduce the history of dirt.

C. To present the change of views on dirt.

D. To stress the role of dirt.

    Giant, krill-eating whales could grow even bigger if the size and availability of their prey (猎物)could keep upa new study finds.

Whales are the heaviest animals to have ever lived on our planet. These marine giants evolved from dog-sized four-legged land creatures and grew nearly 10,000 times bigger in the past 50 million years or so, according to Nicholas Pyenson, head of fossil marine mammals at the Smithsonian's National Museum of Natural History.

Creatures benefit from having a bigger size in a number of different ways, whether it’s not getting eaten by smaller creatures or having the ability to keep warm and travel great distances more efficiently. Still, some whale species are bigger than others, and they do have some limits to their size.

To find out what these limits are researcher attached multisensor equipment to many types of whales. The researcher also assessed prey type and quantity using different methods. For baleen whale preythey used acoustic(声学的) equipment to test the density (密度)of krill patches. For toothed whales, they looked at the size and quantity of squid(鱿鱼)beaks and otoliths (parts of the inner ear) found in the stomachs of beached whales.

Putting all the data together, they could determine how much energy the whales were likely to get back from the food. For toothed whales, the limiting factor seems to be the size of their prey. Sperm whales were found to feed mostly on medium-sized squid—possibly because there aren’t as many giant squid in the ocean. Baleen whales, like blue whales swallow massive mouthfuls of krill or other small creature. But these small creatures only appear in large concentrations for a few months per year in some areas ,which may be the limiting factor for the growth of the largest whales.

A researcher said that it ‘s not completely clear that baleen whales have finished growing. “Perhaps several million years into the future we’ ll see something even larger than a blue whale.”

1.What can we infer from the second paragraph?

A.Whales kept growing during evolution.

B.Whales evolved from dogs on the land.

C.Whales used to be four-legged fish.

D.The number of krill-eating whales would keep up.

2.How do whales benefit from their size?

A.They are more expert at traveling.

B.They can produce energy more easily.

C.They have better chances to survive.

D.They can be eaten by smaller creatures.

3.How did the researchers carry out the study?

A.Testing the density of whales with acoustic equipment.

B.Using different methods for different types of whales.

C.Calculating the amount of food in baleen whales’ stomachs.

D.Assessing the type and quantity of different whales.

4.What may stop whales from growing even bigger?

A.The amount of food.

B.The availability of equipment.

C.The size of their stomachs.

D.The concentrations of the whales.


    In the futurewe may not need to rely on human donations for life-saving skin grafts(移植).

That’s the goal of Xeno Therapeutics, a biotech non-profit organization. The US Food and Drug Administration approved the group’s initial application for temporary skin grafts removed from genetically modified(基因改良)pigs. This means that they can start testing pig skin grafts on people who have experienced severe burns.

Skinthe body’s largest organplays an important role in blocking pathogens(病原体) from reaching our organs inside. It also helps the body keep a constant temperature. People with severe skin damage are at a high risk of developing deadly infections as a result of changes in temperature.

At the moment, the only skin grafts available in the US come from the dead people who have agreed to be organ donors, or patients who have gone through surgery to remove skin after large weight loss. These human skins used for grafts are not easy to find.

Xeno Therapeutics, which gets its name from animal-to-human transplants, has raised pigs that have skin remarkably similar to our own. Grafts from these pigs are therefore more likely to hide without being detected by the host's immune system—at least temporarily. The idea is that they could be used for immediate burn treatment, followed human skin graft treatment later.

“I’d say that just like comparing a Coke with Pepsiit would be hard to tell which was the human skin and which was the pig graft” said Xeno Therapeutics CEO Paul Holzer.

The non-profit organization has been working to conduct the clinical trials, which will only be testing the grafts’ safety and tolerability in six patients with severe burns. Assuming the results are positive after a month, the grafts will need to pass through two more stages of testing before they can be approved for widespread clinical use.

Several other groups around the world are working to make animal organs suitable for clinical medicine. In Brazil, researchers are exploring using tilapia skin as temporary bandages for burn victims whose skin is regrowing.

1.What’s the aim of Xeno Therapeutics?

A.To make profit from the grafts. B.To apply pig skin on human patients.

C.To modify pigs genetically. D.To test people with severe burns.

2.Why is skin important to human body?

A.It acts as a protective layer for our body. B.It helps us recover from deadly diseases.

C.It prevents itself from being damaged. D.It keeps one’s temperature changing.

3.What is Paul Holzer’s attitudes towards the pig skin grafts?

A.Doubtful. B.Worried.

C.Confident. D.Flexible.

4.What can we know about the grafts?

A.Only skin removed from pigs can be used for grafts.

B.Brazilian doctors have also applied pig skin for grafts.

C.Animal skin has been used on six patients safely.

D.They won't be put to use until they pass test


    Not long ago, my wife and I spent a weekend together without any of our three children. This was the first time we had been alone for more than a few hours since our oldest was born four years ago.

What did we do on our short vacation? My wife read the first hundred or so pages of Tom Jones , a book she has been meaning to read for ages. There was takeout and a nice long walk along the shore of Lake Michigan. Football was watched. But mostly? We slept, without worrying for once about whether a shrill voice might awaken us between the hours of 9 p.m. and 6 a.m. to demand a glass of water (“Nonot that onethe Tinkerbell cup!’’. We were too relaxed to do anything else.

As parents, we might tell other people that given the chance for even a short child-free break we would love to do some reading or take in a concert. This is not true. The truth is that what most of us really want is a chance not to think about how well we are using our time.

By admitting thisI realize the myth(错误的看法)of the brain-dead parents. Being brain-dead is what a parent like me looks forward to rather than something to be accused of. The novelist Lucy Ellmann recently provided a convenient summary in an interview

You watch people get pregnant and know they’ll be emotionally and intellectually absent for 20 years. Thought, knowledge, adult conversation, and vital political action are all put on hold. With a kiddo, you become a human koala while your old friends continue to have “interests”. They do art and literature and science, you see, not diapers(尿不湿).

When you become responsible for the life of a very small person, nothing is more important than shouldering that responsibility. In that senseparenting is a chance to reconsider the value of an extra 20 minutes in bed or a short phone conversation with an old friend. As to my wife and me, we spent the weekend eating steamed dumplings and drinking wine until we fell asleep.

We value the all-too-rare experience of being brain-dead.

1.What did the author and his wife mainly do on the weekend?

A.They did some reading. B.They had a sound sleep.

C.They had a nice long walk. D.They watched a football match.

2.What do the underlined words “put on hold” in paragraph 5 refer to?

A.In control. B.Forbidden.

C.Abandoned. D.In vain.

3.How does keeping kids change the author’s life?

A.He begins to feel lonely. B.He is no longer responsible.

C.He becomes absent-minded. D.He hardly has his own time.

4.What’s the best title of the passage?

A.Tips for new parents B.Avoiding being brain-dead parents

C.The myth of brain-dead parents D.How to steal time as brain-dead parents

Wenchuan quake survivor follows in his hero’s footsteps

Twelve years ago, Cheng Qiang was a 12-year-old boy who held a sign1.(say) ''I want to become an airborne trooper(空中骑兵)when I grow up. ''when he saw airborne troops leave 2.their rescue work in the 2008 Wenchuan earthquake. Now Cheng has become a soldier of the Chinese airborne troops, just3. he said he would.

Looking back on the day when the earthquake happened, Cheng had a lucky escape as he had skipped school and4. (go)swimming in a pond in Shifang,Wenchuan.But the earthquake destroyed his home and took away the5.(life)of his little niece and his classmates.

''We survived but fell into despair, not do, '' he said. Then on the second day of the earthquake came the moment he will never forget-a large number of airbome troops appeared in his hometown, carrying rescue supplies. Later, he knew Huang Jiguang was7. at the troop unit.

Huang Jiguang is a Chinese war hero 8.sacrificed(牺牲)himself in the Battle of Shangganling during9. War to Resist US Aggression and Aid Korea in 1952. ''Huang and I both come from Deyang, Sichuan province. The airborne troops are just like my family.'' Cheng said. ''So I made up my mind10.(become)one of them who could bring people strength and hope, '' he said.


Do You Have’ Social Jet Lag(社交时差)

People who have different sleep patterns on the weekends than they do during the work week may experience “social jet lag”.1. For every hour of social jet lag, the risk of being overweight or obese rises about 33%,says researcher Till Roenneberg, PhD, a professor at the Institute of Medical Psychology at the University of Munich.

Roenneberg, who created the term, says social jet lag is caused by the shift in sleep schedule that many people experience on their days off, compared to work days.2.

It goes like this: You don’t have to get up for work so you don’t take trouble setting the alarm. That means you get up an hour or two later than you might during the work week.3.

As a result, many people get more sleep on their days off than they do during the week, and they sleep on a slightly different schedule-a schedule that is closer to their body’s natural rhythms.

4. “The behavior looks like most people on a Friday evening fly from Paris to New York or from Los Angeles to Tokyo and on Monday they fly back. Since this looks like almost a travel jet lag situation, we call it social jet lag.” he says.

5.When you arrive in a different place, the sun is coming up and setting at a different time, and your body can reset its own clock to match. With social jet lag, the schedule disturbance is lasting because a person stays in the same place. “They have to live a life almost in a different time zone in comparison to their biological clock,”Ronneberg says.

A.Sleep, he thinks ,should get more respect.

B.He guesses that it affects about two-thirds of the population.

C.A key difference between travel jet lag and social jet lag, however, is light.

D.And depending on what type of person you are, the difference can be significant.

E.Roenneberg explains switching sleep schedules this way feels like changing time zones.

F.A new study shows this shift in sleep schedule is connected with obesity.

G.You may also push your bedtime back so you can go out with friends.


I remember her words,almost as if they were spoken yesterday.

Mrs.Mabel Price,our high school teacher in that little town of Westminster,in Western Maryland,said,

“You belong in college,and I’m going to do everything I can to get you there.” For me,college was something out of the question,something on a far distant planet,something only those people who had special rights did.I said,”I can’t go to college because I don’t have the money. There’s no way I could afford it.I’m going to join the army.”

Even though I was graduating at the top of my class in that small town,and enjoyed the experience of learning and thinking,I was used to a long tradition of experience in my family.We were people of limited means,and three of my four older brothers had gone off to join the army.

“Being an army man is a perfectly respectable way of life,”she said,”but you have a gift that can make a difference in the world.I want you to continue your education.I think I can get you into Johns Hopkins University.And I’m working on the money.”Finally,I was off to college.

One day I was walking from the parking lot to my first class,talking with my friend and classmate,and we passed by a group of men who were digging a deep ditch(沟渠)Suddenly,I knew why I was in college. She was right-I had been given a gift that could take me to wonderful places.I decided then and there that I preferred to make my living with my brain rather than my back.I had been given a choice they didn’t have:an education.

Some years ago,as I reflected on the experience for many times,it occurred to me:”Maybe I could locate Mrs.Price.Maybe she’s still living in Westminster.I could go back there and visit her,bring her a gift,and really let her know how much I’m thankful for what she had done for me.”

So,I began to search online for information about where she might be.I soon discovered an article about her death,published in the Baltimore Sun and dated October 8,2001.

I suppose the lesson for me in this story-or one of the lessons-is this:If you love someone;if you thank them;if you’re grateful to them-tell them now.One day it will be too late.

Well...anyway...Mrs.Price,wherever you are-thank you.

    Speaking in an interview, Naveen Jain, founder of a space exploration company called Moon Express, said that he believes moon travel is just a decade away. And his company, which is the first private firm to get approval from the U.S. government to carry out the project of moon travel, wants to play a role in helping people get to the moon surface.

''I believe in the next ten years, there is going to be gentlemen on their knees asking their sweethearts, honey, will you go to the moon with me for honey moon?'' Jain said in the interview.

Many people in the technology and scientific communities are crazy about space exploration. Space presents an unprecedented(史无前例的)number of chances for scientific and human advancement. Companies, big and small, are determining how they can create technologies that would allow people to explore space, the moon, and even Mars. Other companies are eyeing ways to play a role in space travel.

The key of that gold rush has been the declining cost of actually getting to space. Jain said that while it once cost billions of dollars to go to the moon, his company's unmanned space flight next year will cost just 7 million. As costs continue to decline(减少),he believes that within the next decade, getting to the moon will cost just $10,000.Better yet, it'll take just four hours to get there.

Still, Mars is the final prize. And even Jain, whose company will focus on moon travel, said that ''Mars is certainly the right place to be finally. '' When asked if he'd like to stage space fights to Mars, Jain said ''of course'', adding that he believes Moon Express could partner with Elon Musk's SpaceX to make that happen.

''Elon will build the rocket and we do the travelers,'' Jain said of a theoretical partnership. ''Generally, he lays the cables and we do the last mile.''

SpaceX and Musk have not said whether they would work alongside Jain and Moon Express. Either way, it looks like hopping from the moon to Mars (and back) might be just a part of our lives.

    When you work out a carbon footprint(碳足迹)a lot of factors are taken into consideration. For example, driving to the grocery store bums a certain amount of fuel, and fossil fuels are the primary sources of greenhouse gases. But that grocery store is powered by electricity, and its employees probably drive to work, so the store has its own carbon footprint. In addition, the products that the store sells were all shipped there, so that must also be factored into the total carbon footprint. Beyond that, the fruits. Vegetables, and meats that the store sells were all grown or raised on farms-a process that produces methane(甲烷)which has a greenhouse effect 25 times greater than CO. All of those elements must be combined to understand the full carbon footprint of a given activity.

Although adding up one's own carbon footprint can be difficult, online calculators can do some of the work for you,giving a rough estimate(估算)of your carbon footprint based on the size of your household, the efficiency of your machines, how much you drive or fly, what you eat, and how much you recycle

This isn't perfect, but it is a good way to measure your activities so you can know roughly how much CO2 they produce and take steps to reduce your carbon footprint.

Methods of reducing your carbon footprint include driving more efficient vehicles (or making sure that your current vehicles are properly maintained), taking public transportation, using energy efficient machines, building your home with special materials to reduce heating and air conditioning costs. consuming food that doesn't require as much transportation, and eating less meat which has a higher carbon footprint than fruits and vegetables. People and companies can also offset some of their CO2, emissions(排放)by purchasing carbon credits, the money from which can go into projects such as planting trees or investing in renewable energy.

1.By giving the example of the grocery store, the author wants to tell us that____

A.driving to the store burns a certain amount of fuel

B.the greenhouse effect of methane is greater than that of CO2

C.the fossil fuels are the primary sources of greenhouse gases

D.many factors need to be considered when figuring out a carbon footprint

2.Which of the following best explains the underlined word ''offset'' in the last paragraph?

A.make up for

B.make sense of

C.take control of

D.catch up with

3.The passage is mainly about____

A.whether it is possible to reduce the carbon footprint

B.what we can do to figure out the carbon footprint to estimate and reduce the carbon footprint

D.why we should reduce the carbon footprint
