1、Animal\'s "Sixth Sense"A tsunami was triggered by an earthquake in the Indian Ocean in December, 2004. It killed tens of thousands of people in Asia and East Africa, Wild animals, however, seem to have escaped that terrible tsunami. This phenomenon adds weight to notions that they possess a "sixth sense" for disasters, experts said.Sri Lankan Wildlife officials have said the giant waves that killed over 24,000 people along the Indian Ocean island\'s coast clearly missed wild beasts, with no dead animals found."No elephants are dead, not even a dead rabbit. I think animals can sense disaster. They have a sixth sense. They know when things are happening" H. D. Ratnayake, deputy director of Sri Lanka\'s Wildlife Department, said about one month after the tsunami attack. The waves washed floodwaters up to 2 miles inland at Yala National Park in the ravaged southeast, Sri Lanka\'s biggest wildlife reserve and home to hundreds of wild elephants and several leopards."There has been a lot of ______ evidence about dogs barking or birds migrating before volcanic eruptions or earthquakes. But it has not been proven," said Matthew van Lierop, an animal behavior assistant at Johannesburg Zoo. "There have been no specialist studies because you can\'t really test it in a lab or field setting," he told Reuters. Other authorities concurred with this assessmetn."Wildlife seem to be able to pick up certain phenmenon, especially birds. There are many reports of birds detecting impending disasters," said Clive Walker, who has written several books on African wildlife.Animals certainly rely on the known senses such as smell or hearing to avoid danger such as predators. The notion of an animal "sixth sense" -or some other mythical power-is an enduring one which the evidence on Sri Lanka\'s ravaged coast is likely to add to. The Romans saw owls as omens of impending disaster and many ancient cultures viewed elephants as sacred animals endowed with special powers or attributes.【单选题】

A.experimental

B.apparent

C.scientific

D.chemical

正确答案:B

答案解析:下一句说，这些迹象并没有被证实。因此，这些迹象不可能是scientific的，而experimental和chemical的词义与上下文不配合，因此也不是答案。只有apparent（明显的）与上下文的意思相配。

2、Some Unusual CelebrationsSome holidays are well - known all around the world. Among them are New Year\'s Eve celebrations. Also common are days in honor of love and friendship, like Valentine\'s Day. Each country has its own special holidays too, often to mark important events in its history. Schools, banks and government offices all close on days like these. Some of the days people celebrate, however, are less serious. A few of them are really very strange.Of course, they are not strange to the people who celebrate them. Perhaps that is because the celebrations have long traditions. Consider April Fool\'s Day, for example. No one knows when or why it began. Today it is celebrated in many countries—France, England and Australia, among others. On this day, people play practical jokes. Jokes are supposed to be funny, but these jokes do not make everyone laugh. The ones who laugh are the ones playing the jokes. The people they fool often get angry. Does celebrating this day make sense to you?Dyngus Day in Poland seems strange too. On this day, it is traditional for boys to pour water over the heads of girls. Here is the strangest part, they do it to girls they like.Other unusual celebrations take place in a single city or town. A holiday called La Tomatina is celebrated in Bunol, Spain. Every year, in late August, big trucks carry more than 200,000 pounds of tomatoes into this little town. _____ For two hours, people in the streets throw tomatoes at each other. Everyone ends up red from head to toe.August 10 marks the start of the Puck Fair, an Irish festival with a very unusual tradition. People from the town of Killorglin go up into the mountains and catch a wild goat. They bring him back to town, put a crown on his head, and make him king for three days.There are also some celebrations that are really strange. In the United States, sometimes one person gets an idea for a new holiday and tries to get others to accept it. Whose idea was Public Sleeping Day? That one is on February 28. It may seem strange, but it sounds like more fun than the one on February 29. That is supposed to be Toothache Day.Do you like the idea of inventing a new holiday? If you do, then you will want to mark March 26 on your calendar. That is Make Up Your Own Holiday Day.【单选题】

A.They bring him back to town, put a crown on his head, and make him king for three days.

B.Some of the days people celebrate, however, are less serious.

C.That is supposed to be Toothache Day.

D.Then begins the world-s biggest food fight.

E.Some people have fun imagining new holidays.

F.Jokes are supposed to be funny, but these jokes do not make everyone laugh.

正确答案:D

答案解析:本段提到了西红柿节，与食物有关，只有提到了食物，把D代入到原文中。符合上下文逻辑，是答案。

3、AIDSAs a science writer, I don\'t have to wear emotional armor very often. Before I went to Zimbabwe for a visit, I had talked to other reporters who had spent time in Africa. All told me to get prepared for the orphans, many of whom had caught the AIDS virus from their mothers and the strong desire to make everything all right for them. Then again, nothing could have prepared me for the visit to creche(育婴堂) for AIDS orphans in Harare, where one sick, smiling four-year-old boy tried to keep up with the other kids playing ring-around-the-rosy but was so weak he kept falling to the floor, or meeting a 25-year-old unmarried girl who cared for her nephew Only when I got back about a week later The boy who called his aunt "Mama" was too weak even to take the piece of banana I offered. Meanwhile photojournalist Karin Retief was visiting a room at the hospice (济贫院) where she had been told a particularly sweet orphan boy stayed. At first she did not see anyone on the bed and was about to say he must be elsewhere, when suddenly she spotted his tiny arm in the air, his body lost in the folds of the bedclothes. Recently Karin wrote to me that she had been able to keep our assignment from taking too great an emotional suffering at the time. " ______, could I moum the people I met", she continued. "I sat in church and wanted to ask the priest to pray for the people with AIDS in Zimbabwe and all over the world. Then all the people\'s faces, pain and suffering became so real, I could not get the words out. I broke down and cried and cried for them". 【单选题】

A.where she had been told a particularly sweet orphan boy stayed

B.who had spent time in Africa

C.Only when I got back about a week later

D.even though her only income was from growing and selling a few vegetables at the local market

E.was so weak he kept falling to the floor

F.while we were visiting the orphans

正确答案:C

答案解析:句首需要大写，选项中只有C的开头是大写。另外后面的句子是倒装语序，就要考虑某些特殊的句式结构。因此选C。

4、Rockets in the SkyIf someone asked you. "What color is the sky?" I expect that you would answer, "Blue." I am afraid that you would be wrong. The sky has no color. When we see blue, we are looking at blue sunlight. The sunlight is shining on little bits of dust in the air. We know that there is air all around the world. We could not breathe without air. Airplanes could not fly without air. They need air to lift their wings. Airplanes cannot fly very high because as they go higher the air gets thinner. If we go far enough away from the earth, we find there is no air. What is the sky? The sky is space. In this space there is nothing except the sun, the moon and all the stars. Scientists have always wanted to know more about the other worlds in the space. They have looked at them through telescopes and in this way they have found out a great deal. The moon is about 384,000 kilometers away from the earth. An airplane cannot fly to the moon but there is a thing that can fly even when there is no air. This is rocket. I am sure that you are asking. "How does a rocket fly?" If you want to know, get a balloon and then blow it up until it is quite big. Do not tie up the neck of the balloon. Let go! The balloon will fly off through the air very quickly. The air inside the balloon tries to get out. It rushes out through neck of the ball off and this pushes the balloon through the air. It does not need wings like an air plane. This is how a rocket works. It is not made of rubber like a balloon, of course. It is made of metal. The metal must not be heavy but it must be very strong. There is gas inside the rocket which is made very hot. When it rushes out of the end of the rocket, the rocket is pushed up into the air. Rockets can fly far out into space. Rockets with men inside them have already reached the moon. Several rockets, without men inside them, have been sent to other worlds much farther away. One day rockets may be able to go anywhere in the space. A rocket is pushed up into the air when____. 【单选题】

A.hot gas rushes out of its head.

B.it is powered by gas.

C.hot gas rushes out of its bottom.

D.hot gas rushes out of its neck.

正确答案:C

答案解析:根据文章倒数第2段最后一句( When it rushes out of the end of the rocket)。

5、One Good Reason to Let Smallpox LiveIt\'s now a fair bet that we will never see the total extinction (灭绝) of the smallpox (天花) virus. When smallpox was completely got rid of in the world, scientists wanted to destroy the killer virus in the last two labs, one in the US and one in Russia. They asked: If smallpox has truly gone from the planet, _____ point was there in keeping these reserves?In reality, of course, it was naive to imagine that everyone would let go of such a powerful potential weapon. Undoubtedly several nations still have a few vials (小药瓶). And the last "official" stocks of live Virus bred mistrust of the US and Russia, for no obvious gain.Now American researchers have found an animal model of the human disease, opening the way for tests on new treatments and vaccines(疫苗). So once again there\'s a good reason to the virus, just in keep the disease puts in a reappearance.How do we case with the mistrust of the US and Russia? deal. Keep the virus Simple international support in a well - guarded UN laboratory that\'s open to all countries. The US will object, of course, just as it with a multilateral (多边的) approach to just about everything. But it doesn\'t mean the idea is rejects. If the virus is useful, then let\'s wrong it the servant of all humanity make not just a part of it.【单选题】

A.which

B.that

C.this

D.what

正确答案:D

答案解析:本题有一定难度，考查what point的用法，干扰项有一定的干扰。what point，固定搭配，指“什么意义”，可引导问句，文章此处是说“科学家说如果天花真的在这个星球上消失了，保留这些储备病毒的还有什么意义？”答案是D。

6、Seeing Red Means Danger AheadThe color red often means danger and by paying attention, accidents can be prevented. In the future, the color red also may help prevent danger at construction sites. Thanks to new work by engineers, bridge supports or other kinds of materials could one day contain a color switching material. It will turn red before a structure collapses or falls apart. The secret behind the color switching material is a particular type of molecule. A molecule is a group of atoms held together by chemical bonds. Molecules come ______ all shapes and sizes, and make up everything. You can see, touch or feel. How a molecule behaves depends on what kinds of atoms it contains, and how they\'re held together. When a polymer (聚合物) containing a color switching molecule called a mechanophore (机械响应性聚合物) which is about to break, it produce a color. When a polymer with mechanophore molecules becomes "injured" or weak, one of the mechanophore bonds breaks and the material turns red. "It\'s a really simple detection method. "says Nancy Sottos, one of the scientists who worked on the project. Sottos and her team tested the color switching polymers in their lab. The test results proved encouraging. There is a way to get rid of the color light when a bright light is shone on the mechanophore. The broken bond is fixed and the red color disappears. This "self-healing" may be a problem for engineers. They need to use the color changer in big construction projects that will be outside in sunlight. And sunlight will make the mechanophore\'s warming system useless. Sottos and her fellow scientists still have a lot of work to do before the color switching molecules can be used outside the lab. 【单选题】

A.for

B.in

C.from

D.at

正确答案:D

答案解析:come at shapes and sizes，习惯用法。

7、Walking to Exercise the BrainDo you think sitting and studying all the time will improve students grades? Think again. Getting some exercise may help, too.New research with older people suggests that taking regular walks helps them pay attention better than if they didn\'t exercise.Previous research had shown that mice learn, remember and pay attention better after a few weeks of working out on a running wheel. Mice that exercise have greater blood flow to the brain than those who don\'t. Their brain cells also make more connections.Neuroscientists (神经科学家) from the University of Illinois at Urbana Champaign wanted to find out if the same thing is true for people. First, they measured the physical fitness of 41 adults, ages 58 to 77, after each person walked I mile. Then, participants looked at arrows on a computer screen and had to use computer keys to show which way one particular arrow was pointing.Adults who were physically fit were faster at the arrow task, and their answers were just as accurate as their less - fit peers, the researchers found. The fitter participants also had more blood flow to a part of their brain responsible for paying attention and making decisions.In a second study, 15 elderly people who completed a 6 - month aerobic - training (有氧运动) course were faster at attention tasks compared with 14 seniors who just did stretching and toning (韵律操) exercises for the same amount of time.So, even going for a walk every 2 or 3 days for just 10 to 45 minutes can help. That should be good news for the elderly.The effects of exercising on the brains of younger people haven\'t been studied yet. Still, it can\'t hurt to take occasional breaks and go for a walk or run around with friends. Whatever you do, though, don\'t try to read and walk at the same time. You could end up hurting yourself!Walking regularly helps elderly people ______.【单选题】

A.lose weight

B.become happier

C.concentrate better

D.look younger

正确答案:C

答案解析:本题难度不大，找到答案依据不难。答案依据在文章第二段。第二段谈到新的研究表明，相对于不锻炼，经常散步有助于帮助老年人更好集中精力，回来看选项，很明显，C是近义解释，是答案。

8、There is always excitement at the Olympic Games when an athlete breaks a record.【单选题】

A.beats

B.maintains

C.matches

D.tries

正确答案:A

答案解析:运动员在奥运会上打破记录时总让人兴奋。本题有一定难度，考查的是引申意义，beat的基本意义是“击打”，引申意义有“打破记录”的意思，和break是近义词，其他选项都是常用词汇，和答案意义差异大，最佳答案是A。

9、Seeing Red Means Danger AheadThe color red often means danger and by paying attention, accidents can be prevented. In the future, the color red also may help prevent danger at construction sites. Thanks to new work by engineers, bridge supports or other kinds of materials, could one day contain a color - changing material. It will turn red before a structure collapses or falls apart.The secret behind the color - changing material is a particular type of molecule (分子). A molecule is a group of atoms (原子) held together by chemical bonds. Molecules come in all shapes and sizes and make up everything you can see, touch or feel. How a molecule behaves depends on what kinds of atoms it contains and how they\'re held together.When a polymer (聚合物) containing a color - changing molecule called a mechanophore (机械响应性聚合物) is about to break, it produces a color. When a polymer with mechanophore molecules becomes "injured" or weak, one of the mechanophore bonds breaks and the material turns red. "It\'s a really simple detection method," says Nancy Sottos, one of the scientists who worked on the project. Sottos and her team tested the color - changing polymers in their lab. The test _____ proved encouraging.There is a way to get rid of the red color light. When a bright light is shone on the mechanophore, the broken bond is fixed and the red color disappears. Thus "self - healing" may be a problem for engineers. They need to use the color - changer in big construction projects that will be outside, under sunlight. And sunlight will make the mechanophore\'s warning system useless.Sottos and her fellow scientists still have a lot of work to do before the color - changing molecules can be used outside the lab.【单选题】

A.results

B.rules

C.tools

D.methods

正确答案:A

答案解析:本题难度不大，考查的是词义辨析。很明显，文章此处的意思是“结果”，答案是A。
