1、Science Fiction1 Amongst the most popular books being written today are those that are usually classified asscience fiction. Hundreds of titles are published every year ａｎｄ　are read by all kinds of people. Furthermore, some of the most successful films of recent years have been based on science fiction stories. 2 It is often thought that science fiction is a fairly new development in literature, but its ancestors can be found in books written hundreds of years ago. These books were often concerned with the presentation of some forms of ideal society, a theme that is still often found in modern stories. 3 Most of the classics of science fiction, however, have been written within the last hundred years. Books by writers such as Jules Verve ａｎｄ　H. G Wells, to mention just two well known authors, have been translated into many languages. 4 Modern science fiction writers don\'t write about men from Mars ｏｒspace adventure stories. They are more interested in predicting the results of technical developments on society ａｎｄ　the human mind; ｏｒin imagining future worlds that are a reflection of the world that we live in now. Because of this their writing has obvious political undertones (涵义). 5 In an age where science fact frequently overtakes (超过) science fiction, the writers may find it difficult to keep ahead of scientific advances. Those who are sufficiently clear-sighted to see the way we are going, however, may provide a valuable lesson on how to deal with the problems which society will inevitably face as it tries to master its new technology. Some form of ideal society is____. 【单选题】

A.concerned with the problems that we will have to solve in the future

B.reading books of science fiction

C.political implication

D.a recurrent theme

E.read worldwide

F.translated into many languages

正确答案:D

答案解析:本题答案的依据是在第2段最后一句，句中的theme指该句的前半部分，而atheme that is still often found in modern stories这句话换一种说法就成了a recurrent theme（一个反复出现的主题），故选D。

2、Keeping Cut Flowers1 While everybody enjoys fresh cut flowers around his house, few people know how to keep them fｏｒas long as possible. This may be done by keeping in mind a few simple fact. 2 An important thing to remember about cut flowers is that they are sensitive to temperature. Fｏｒexample, studies have shown that cut carnations (康乃馨) retain their freshness eight times longer when kept at 12℃ than when kept at 26℃. Keeping freshly harvested flowers at the right temperatures is probably the most important aspect of flower care. 3 Flowers are not intended by nature to live very long. Their biological purpose is simply to attract birds ｏｒinsects, such as bees, fｏｒpollination (粉). After that, they quickly dry up ａｎｄ　die. The process by which flowers consume oxygen ａｎｄ　produce carbon dioxide, called respiration, generates the energy the flower needs to give the flower its shape ａｎｄ　color. The making of seeds also depends on this energy. While all giving things respire, flowers have a high level of respiration. A result of all this respiration is heat, ａｎｄ　fｏｒflowers the level of heat relative to the mass of the flower is very high. Respiration also brings about the eventual death of the flower. Thus the greater the level of respiration, the sooner the flower dies. 4 How, then, to control the rate at which flowers die? By controlling respiration. How is respiration controlled? By controlling temperature. We know that respiration produces heat, but the reverse is also true. Thus by maintaining low temperatures, respiration is reduced ａｎｄ　the cut flower will age more slowly. 5 Another vital factｏｒin keeping cut flowers is the quality of the water in which they are placed. Flowers find it difficult to "drink" water that is dirty ｏｒotherwise polluted. Even when water looks ａｎｄ　smells clean, it almost certainly contains harmful substances that can endanger the flowers. To rid the water of these unwanted substances, household chlorine bleach (含氯漂白剂) can be used in small quantities. It is recommended that 15 drops of chlorine bleach (at 4% solution) be added to each liter of water. The water ａｎｄ　solution should also be replaced each day. Respiration plays a key role____. 【单选题】

A.by keeping its original shape ａｎｄ　color

B.in the life ofthe cut flower

C.to produce carbon dioxide

D.fｏｒas long as possible

E.by controlling temperature

F.to replace the water ａｎｄ　solution every day

正确答案:B

答案解析:本题其实与上面第24题意思相似，都是在说呼吸的作用。通过对第24题的分析我们知道呼吸在花朵一生中起到了重要作用，选项B符合题意，故选B。

3、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。

4、Rodman met with Tony to try ａｎｄ　settle the dispute over his contract.【单选题】

5、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 behind 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 _____ 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.closes

B.breaks

C.increases

D.burns

正确答案:B

答案解析:本题有一定难度，关键在理解好文章上下文意义，文章此处要表达的是“断开”的意思，答案是B。
