1、Better Control of TB Seen if a Faster Cure is FoundThe World Health Organization estimates that about one-third of all people are infected with bacteria that cause tuberculosis. Most times, the infection remains inactive. But each year about eight million people develop active cases of TB, usually in their lungs. Two million people die of it. The disease has increased with the spread of AIDS and drug-resistant forms of tuberculosis. Current treatments take at least six months. Patients have to ______ a combination of several antibiotic drugs daily. But many people stop as soon as they feel better. Doing that can lead to an infection that resists treatment. Public health experts agree that a faster-acting cure fortuberculosis would be more effective. Now a study estimates just how effective it might be. A professorof international health at Harvard University led the study. Joshua Salomon says a shorter treatment program would likely mean not just more patients cured. It would also mean fewer infectious patients who can pass on their infection to others. The researchers developed a mathematical model to examine the effects of a two-month treatment plan. They tested the model with current TB conditions in Southeast Asia. The scientists found that a two-month treatment could prevent about twenty percent of new cases. and it might prevent about twenty-five percent of TB deaths. The model shows that these reductions would take place between two thousand twelve and two thousand thirty. That is, if a faster cure is developed and in wide use by two thousand twelve. The World Health Organization developed the DOTS program in nineteen ninety. DOTS is Directly Observed Treatment, Short-course. Health workers watch tuberculosis patients take their daily pills to make sure they continue treatment. Earlier this year, an international partnership of organizations announced a plan to expand the DOTS program. The ten-year plan also aims to finance research into new TB drugs. The four most common drugs used now are more than forty years old. The Global Alliance forTB Drug Development says its long-term goal is a treatment that could work in as few as ten doses.【单选题】

A.make

B.take

C.try

D.test

正确答案:B

答案解析:从本句的前后句可以推测到本句想说的是“病人每天必须服用几种抗生素药物”,而服药只能选择take,其他几个动词都不合适。

2、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 theory 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 _____ 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.would

B.will

C.must

D.need

正确答案:A

答案解析:本题有一定难度,考查虚拟语气和时态一致的用法,干扰项有一定的干扰。根据上下文逻辑,文章此处是说“爱因斯坦的计算帮助Bose理论成立,即原子会象原来他设想的那样运行”,此处只是表示理论成立,而不等于是经过验证的科学事实,所以要用假设的语气,此外整个句子都是用的过去时态,因此答案是A。

3、Rockets in the SkyIf someone asked you. "What coloris 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 can fly to the moon because____. 【单选题】

A.it looks like a balloon.

B.it is much lighter than an airplane.

C.it doesn\'t have wings.

D.it works like an untied balloon.

正确答案:D

答案解析:文章第6段都在综述气球的飞行原理来解释火箭的工作原理,因此选D。

4、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. One advantage of keeping a record of your spending is that____. 【单选题】

A.you will remember how much you have already spent

B.you will know if you have spent more money than you planned

C.you will be able to tell your family what should not be bought

D.you will learn how to make a better budget next time

正确答案:B

答案解析:第5段讲了“Studying your records will show where overspending has occurred. It will also point out poorbuying habits”(消费记录可以找出哪里超支了,或者可以发现一些不良购买习惯)。所以B是正确答案。

5、Light Night, Dark StarsThousands of people around the globe step outside to gaze at their night sky. On a clear night, with no clouds, moonlight, orartificial lights to block the view, people can see more than 14,000 stars in the sky, says Dennis Ward, an astronomer(天文学家) with the University Corporation forAtmospheric Research( UCAR) in Boulder, Colo. But when people are surrounded by city lights, he says, they\'re lucky to see 150 stars.If you\'ve ever driven toward a big city at night and seen its glow from a great distance, you\'ve witnessed light pollution. It occurs when light from streetlights, office buildings, signs, and other sources streams into space and illuminates (照亮) the night sky. This haze (朦胧) of light makes many stars invisible to people on Earth. Even at night, big cities like New York glow from light pollution, making stargazing difficult.Dust and particles of pollution factories and industries worsen the effects of light pollution. "If one city has a lot more light pollution than another," Ward says, "that city will suffer the effects of light pollution on a much greater scale."Hazy skies also make it far more difficult forastronomers to do their jobs.Cities are getting larger. Suburbs are growing in once dark, rural areas. Light from all this new development is increasingly obscuring (使变模糊) the faint (微弱的) light give off by distant stars. and if scientists can\'t locate these objects, they can\'t learn more about them.Light pollution doesn\'t only affect star visibility. It can harm wild life too. It\'s clear that artificial light can attract animals, making them go off course. There\'s increasing evidence, forexample, that migrating (迁徙) birds use sunsets and sunrises to help find their way, says Sydney Gauthreaux Jr. , a scientist at Clemson University in South Carolina, "When light occurs at night," he says, "it has a very disruptive (破坏性的) influence." Sometimes birds fly into lighted towers, high - rises, and cables from radio and television towers. Experts estimate that millions of birds die this way every year.How does light pollution affect wildlife? ______【单选题】

A.Animals may go off course.

B.It helps migrating birds find their homes.

C.Animals are afraid to go out after sunset.

D.It helps birds fall asleep.

正确答案:A

答案解析:本题难度不大,答案依据比较明显,在文章第六段第三句,这句话谈到,人造光源会误导动物,造成动物偏离飞行路线,回来看选项,A项符合原文句意,是答案。
