1、Breastfeeding Can Cut Cardiovascular RiskBreastfeeding can reduce the risk of a heart attack ｏｒstroke later in life ａｎｄ　could prevent hundreds of thousands of deaths each year, researchers said on Friday. Babies who are breastfed have fewer childhood infections ａｎｄ　allergies ａｎｄ　are less prone to obesity. British scientists have now shown that breastfeeding ａｎｄ　slow growth in the first weeks ａｎｄ　months of life has a protective effect against cardiovascular disease. "Diets that promote more rapid growth put babies at risk many years later in terms of raising their blood pressure, raising their cholesterol ａｎｄ　increasing their tendency to diabetes ａｎｄ　obesity-the four main risk factors fｏｒstroke ａｎｄ　heart attack." said ProfessｏｒAlan Lucas of the Institute of Child Health in London. "Our evidence suggests that the reason why breast-fed babies do better is because they grow more slowly in the early weeks."Lucas said the effects of breastfeeding on blood pressure ａｎｄ　cholesterol later in life are greater than anything adults can do to control the risk factors fｏｒcardiovascular disease, other than taking drugs. An estimated 17 million people die of cardiovascular disease, particularly heart attack ａｎｄ　strokes, each year, according to the World Health Organization. Lucas ａｎｄ　his colleagues compared the health of 216 teenagers who as babies had either been breastfed ｏｒgiven different nutritional baby formulas\' They reported their findings in The Lancet medical journal. The teenagers who had been ______ had a 14 percent lower ratio of bad to good cholesterol ａｎｄ　lower concentrations of a protein that is a marker fｏｒcardiovascular disease risk. The researchers also found that regardless of the child\'s weight at birth, the faster the infants grew in the early weeks ａｎｄ　months of life, the greater was their later risk of heart disease ａｎｄ　stroke. The effect was the same fｏｒboth boys ａｎｄ　girls. "The more human milk you have in the newborn period, the lower your cholesterol level is, the lower your blood pressure is 16 years later, "Lucas said. 【单选题】

A.surveyed

B.interviewed

C.handled

D.breastfed

正确答案:D

答案解析:选项D是文章主题词，因此成为答案的可能性较大。从句意看，该句讲述“曾经的青少年中坏胆固醇与好胆固醇的比率要低14%，而且他们的蛋白质积聚也较低，而蛋白质的积聚是患心血管疾病风险高低的标志之一”。文章主题是“母乳喂养能够减少心血管疾病的危险”，由此推测出现这种较好健康情况的人应该是“母乳喂养的人”，因此答案是D。

2、A Star Is Born1 The VLT (Very Large Telescope) is the world\'s largest telescope ａｎｄ　is taking astronomers further back to the Big Bang than they ever thought possible. Located 2,600 meters up to the Chilean Andes, it has four huge mirrors, each about the size of a London bus. The VLT is so powerful it can spot a burning match 10, 000 kilometers away. 2 This astonishing power will allow astronomers to see events in space from the birth of stars to the collision of galaxies on the edge of the cosmos. The VLT is giving astronomers their best ever view of the cosmos. The power of the VLT to see the smallest detail at the furthest distances makes its designers amazed. 3 Take the case of Eta Carinae, one of the most explosive stars in the universe. This star produces ultraviolet laser rays (紫外线) ａｎｄ　it will destroy itself in a few million years\' time. It is five times brighter than the sun ａｎｄ　when it explodes it is going to be a sight worth waiting for. 4 But it is at distances of millions, even billions, of light years that the VLT really shows its power. The VLT can detect light that ｓｅｔout on its journey before the earth even existed. This gives astronomers their first ever detailed views of events that took place in the earliest days of the cosmos. 5 In other words, the VLT is a kind of a time machine. It takes astronomers back to a time when complete galaxies crashed into each other. The effects of these past collisions can now be seen by scientists, ａｎｄ　astronomers believe the telescope will reveal more about these exciting events in the years to come. One day, we might be able to say we have traveled back to the beginning of time, ａｎｄ　we will have a much clearer picture of how our planet was born. The designers of the VLT are surprised at____. 【单选题】

A.its detecting power

B.millions of light years away in space

C.the location of the VLT

D.as an example

E.the birth of the earth

F.the rotation of the earth

正确答案:A

答案解析:文章第2段最后一句也概括提到了这句话的意思。

3、Sharing SilenceDeaf teenagers Orlando Chavez ａｎｄ　German Resendiz have been friends since kindergarten (幼儿园). Together the two boys, who go to Escondido High School in California, have had the difficult job of learning in schools where the majority of the students can speak ａｎｄ　hear.Orlando lost his hearing at the age of one. German was born deaf, ａｎｄ　his parents moved from Mexico to find a school where he could learn sign language. He met Orlando on their first day of kinder garten."We were in a special class with about 25 other deaf kids," German remembered. "Before then, I didn\'t know I was deaf ａｎｄ　I was different.""Being young ａｎｄ　deaf in regular classes was very hard," signs Orlando. "The other kids didn\'t understａｎｄ　us ａｎｄ　we didn\'t understａｎｄ　them. But we\'ve all grown up together, ａｎｄ　today, I\'m popular because I\'m deaf. Kids try to communicate with me."Some things are very difficult fｏｒthe two boys. "We can\'t talk on the phone, so if we need help, we can\'t call an emergency service," German signs. "ａｎｄ　we can\'t ｏｒｃｅｒfood in a drive - thru."Despite of their difficulties, the two boys have found work putting food in bags at a local supermarket.They got their jobs through a "workability" program, designed fｏｒteenagers from local schools with different types of learning disabilities.German has worked in the supermarket since August, ａｎｄ　Orlando started in November."The other people who work here nave been very nice to us," Orlando signs. "They even sign sometimes. At first, we were nervous, but we\'ve learned a lot ａｎｄ　we\'re getting better."The opportunity to earn money has been exciting, both boys said. After high school, they hope to attend the National Technical Institute fｏｒthe Deaf in New York.The word "emergency" in paragraph 5 is closest in meaning to ______.【单选题】

A.food

B.alarm

C.crisis

D.quick

正确答案:C

答案解析:本题难度不大，干扰项干扰不强，考生会很快确定答案。emergency指“紧急”，和crisis“危机，紧急关头”是近义词。B项alarm指“警戒”，最佳答案是C。

4、Seeing Red Means Danger AheadThe colｏｒred often means danger ａｎｄ　by paying attention, accidents can be prevented. In the future, the colｏｒred also may help prevent danger at construction sites. Thanks to new work by engineers, bridge supports ｏｒother kinds of materials, could one day contain a colｏｒ- changing material. It will turn red before a structure collapses ｏｒfalls apart.The secret _____ the colｏｒ- changing material is a particular type of molecule (分子). A molecule is aｇｒｏｕｐof atoms (原子) held together by chemical bonds. Molecules come in all shapes ａｎｄ　sizes ａｎｄ　make up everything you can see, touch ｏｒfeel. 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" ｏｒweak, 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 results proved encouraging.There is a way to get rid of the red colｏｒlight. When a bright light is shone on the mechanophore, the broken bond is fixed ａｎｄ　the red colｏｒdisappears. Thus "self - healing" may be a problem fｏｒengineers. 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.on

B.behind

C.under

D.down

正确答案:B

答案解析:本题有一定难度，干扰项干扰较大，考查介词behind的用法，文章此处是说，“材料颜色可以变化其背后的秘密是……”，只有behind可以表示“背后的”意思，答案是B。

5、Storms Sink ShipsRescuers have found the bodies of over 130 people killed in two ferry disasters in Bangladesh. The accidents happened during a storm that hit the country on April 21. Hundreds more are missing ｏｒfeared dead. The two ferries sank in different rivers near the capital city of Dhakfi as strong winds ａｎｄ　rain hit the South Asian country. The government has since banned all ferries ａｎｄ　other boats from traveling at night during the April-May stormy season. One of the ferries, MV Mitali, was carrying far more people than it was supposed to. About 400 passengers fitted into a space made fｏｒjust 300, police said. The second ferry carried about 100 passengers. "The number of deaths is certain to rise." said an official in charge of the rescue work. "No one really knows how many people were on board the ferry ｏｒhow many of them survived. Ferries in Bangladesh don\'t always keep passenger lists, making it difficult to determine the exact number of people on board. Besides the ferry accidents, at least 40 people were killed ａｎｄ　400 injured by lightning strikes, falling houses ａｎｄ　trees ａｎｄ　the sinking of small boats. Storms are common this time of year in Bangladesh, as are boating accidents. Ferry disasters take away hundreds of lives every year in a nation of 130 million people. Officials blame these river accidents on a lack of safety measures too many passengers in boats ａｎｄ　not enough checks on weather conditions. Ferries are a common means of transport in Bangladesh. It is a country covered by about 230 rivers. Some 20,000 ferries use the nation\'s Waterways every year. ａｎｄ　many of them are dangerously overcrowded. Since 1977, more than 3,000 people have died in some 260 boating accidents.How many passengers was MV Mitali designed to carry?【单选题】

A.500

B.100

C.400

D.300

正确答案:D

答案解析:该题问的是：渡船MV Mitali设计载客量是多少？答案在第4段第2句：把大约400个旅客装进了只能容纳300个旅客的空间。

7、The Hurricane1. A hurricane (飓风) is a tropical storm with winds that have reached a constant speed of 74 miles per hour. Hurricane winds blow in a large spiral(螺旋) around a relative calm center known as the "eye". The "eye" is generally 20 to 30 miles wide, ａｎｄ　the storm may extend outward 400 miles. As a hurricane nears land, it can bring heavy rains, high winds ａｎｄ　storm surges(风暴潮). The storm surges ａｎｄ　heavy rains can lead to flooding.2. Hurricanes are given a different label, depending on where they occur. If they begin over the North Atlantic Ocean, the Caribbean Sea, The Gulf of Mexico, ｏｒthe Northeast Pacific Ocean, they are called hurricanes. Similar storms that occur in the Northwest Pacific Ocean west of the Internaional Date Line are called typhoons near Australia ａｎｄ　in the Indian Ocean, they are referred to as tropical cyclones(龙卷风).3. When a hurricane hits land, it can do great damage through its fierce winds, heavy rains, inland(内陆的) flooding ａｎｄ　huge waves crashing on to the shore. During a hurricane, homes, businesses ａｎｄ　public buildings may be damaged ｏｒdestroyed, roads ａｎｄ　bridges can be washed away. A powerful hurricane can kill more people ａｎｄ　destroy more property than any other natural disaster. Fishermen are at special risk from hurricanes as they may be at sea when a hurricane arrives ａｎｄ　not be able to get to a safe harbｏｒif they do not receive adequate warning.4. If a hurricane is comming in your area, the most important thing is to stay calm ａｎｄ　find shelter immediately. Go to your safe room. If you do not have one, stay indoors during the hurricane ａｎｄ　go to a safer place near the center of your home. Cover yourself with a blanket ａｎｄ　be sure to keep away from windows ａｎｄ　glass doors, because if the glass breaks it’s really dangerous. Do not be fooled if there is lull(暂停), it could be the eye of the storm—winds will pick up again.During a hurricane one should stay away from ______.【单选题】

A.different labels

B.window ａｎｄ　glass doors

C.inlａｎｄ　flooding

D.early warning

E.natural disaster

F.a constant speed

正确答案:B

答案解析:本题难度不大，答案依据比较明显，在文章最后一段的第三句：Cover yourself with blanket ａｎｄ　be sure to keep away from windows ａｎｄ　glass doors，…回来看选项，B项符合原文句意，是答案。

8、The Book of LifeSo far, scientists have named about 1.6 million living species, ａｎｄ　that\'s a just a fraction of that probably exists on Earth. With so many plants, animals ａｎｄ　other creatures coveting the planet, it can be tough to figure out what type of spider is moving up your leg ｏｒwhat kind of bird is flying by.A soon - to - be - started Web site might help. An international team of researchers has announced the creation of Web - based Encyclopedia of life( EOL). The project aims to catalog every species on Earth in a single, easy - to - use reference guide.To get the encyclopedia started, the creators will use information from scientific ｄａｔａｂａｓｅs that already exist. ａｎｄ　eventually, in special sections of the site, nonscientist with specialized knowledge will get to join in. Bird - watchers, fｏｒexample, will be able to input which bird they\'ve seen ａｎｄ　where. The technology fｏｒthis kind of tool has only become available.As the EOL develops, you might find it useful fｏｒschool projects. The site will feature special pages fｏｒkids who are studying ecosystems (生态系统) in their neighborhoods. To make sure the encyclopedia is accurate, scientists will review much of the information added to it. People who visit the site will be able to choose to leave out pages that haven\'t been reviewed.Another convenient feature of the EOL is that you\'ll be able to pick the level of detail you want to see to match your interest, age ａｎｄ　knowledge. If you wanted to learn about bears fｏｒa science class report, fｏｒexample, you could use the "novice" setting to get basic information about the animals. On the "expert" setting, on the other hand, you could get much more detailed information about the history, literature ａｎｄ　exploration of bears.It now takes years fｏｒscientist to collect all the data they need to describe ａｎｄ　analyze species. The creatｏｒof the Encyclopedia of Life hope that their new tool will speed up that process."Spider" ａｎｄ　"bird" mentioned in Paragraph 1 are examples to illustrate ______.【单选题】

A.there are numerous living species on Earth

B.animals are people\'s friends

C.it is easy to see spiders ａｎｄ　birds

D.here are many types of spiders ａｎｄ　birds

正确答案:A

答案解析:本题有一定难度，带着题干信息词回文章定位，答案依据主要在文章第一段：So far, scientists have named about l.6 million living species, ...it can be tough to figure out what type of spider is moving up your leg ｏｒwhat kind of bird is flying by.谈到了地球物种数量巨大，回来看选项，A项和原文句意相近，是答案。

9、BudgetA budget is a spending plan. It can help you spend money wisely. It can do this by cutting out wasteful spending. Of course, preparing a budget takes planning, ａｎｄ　following a budget takes will power. Your budget should meet your family\'s needs ａｎｄ　income. The first step in creating a budget is to ｓｅｔyour goals. What does your family need ａｎｄ　wants. You must know this to work out the details of the budget. Keep goals realistic, in terms of income available. Then decide which goals are the most important. The next step is estimating family income. Before you can plan wisely, you need to know how much money you have to spend! Write down all the money you expect to receive (wages, savings, interest, etc.) during the planned budget period. After you have calculated how much money will be available, it is time to estimate expenses. List all of your family expenses. If you are not satisfied with what you got fｏｒyour money, look carefully at your spending. Studying your records will show where overspending has occurred. It will also point out poｏｒbuying habits. It is also a good idea to ｓｅｔaside a small amount of money fｏｒemergencies. Every family has small emergencies: a blown tire, a broken device, ｏｒthe need fｏｒminｏｒmedical care. This passage is mainly about____. 【单选题】

A.the meaning of a budget

B.the relation between budget ａｎｄ　income

C.the way in which a budget is made

D.the importance of making a budget

正确答案:C

答案解析:本文从预算的作用开始引入，到第2段开始分步骤地介绍了进行预算的方式，主要讲的是进行预算的方法问题。

10、What Is the Coolest Gas in the Universe?What is the coldest air temperature ever recorded on the Earth? Where was this low temperature recorded? The coldest recorded temperature on Earth was - 91℃, which occurred in Antarctica (南极洲) in 1983.We encounter an interesting situation when we discuss temperatures in space.Temperatures in Earth orbit actually range from about +120℃ to - 120℃. The temperature depends upon whether you are in direct sunlight ｏｒshade. Obviously, -120℃ is colder than our body can safely endure. Thank NASA science fｏｒwell, de signed space suits that protect astronauts from these temperature extremes.The space temperatures just discussed affect only our areal of the solar system. Obviously, it is hotter closer to the Sun ａｎｄ　colder as we travel away from the Sun. Astronomers estimate temperatures at Pluto are about - 210℃. How cold is the lowest estimated temperature in the entire universe? Again, it depends upon your location. We are taught it is supposedly impossible to have a temperature below absolute zero, which is - 273℃, at which atoms do not move. Two scientists, whose names are Cornell ａｎｄ　Wieman, have successfully cooled down a gas to a temperature barely above absolute zero. They won a Nobel Prize in Physics in 2001 fｏｒtheir work, not a discovery, in this case.Why is the two scientists\' work so important to science?In the 1920s, Satyendra Nath Bose was studying an interesting ______ about special light particles we now call photons (光子). Bose had trouble convincing other scientists to believe his theory, so he contacted Albert Einstein. Einstein\'s calculations helped him theorize that atoms would behave as Bose thought—but only at very cold temperatures.Scientists have also discovered that ultra - cold(超冷) atoms can help them make the world\'s atomic clocks even more accurate. These clocks are so accurate today they would only lose one second every six million years! Such accuracy will help us travel in space because distance is velocity times time 4 ( d = v×t). With the long distances involved in space travel, we need to know time as accurately as possible to get accurate distance.【单选题】

A.invention

B.experiment

C.theory

D.paper

正确答案:C

答案解析:本题有一定难度，考查词义辨析，干扰项有一定的干扰。根据上下文逻辑，文章此处是说“……在研究有关光子的一种有意思的理论”，答案是C。
