1、Houses of FutureWhat will houses be like in thirty years\' time? No one really knows, but architects are trying to predict what our home will be likeE. Future houses will have to be flexible. In thirty years\' time even more of us will be working at home. So we will have to be able to use areas of the house fｏｒwork fｏｒpart of the day ａｎｄ　fｏｒliving fｏｒthe rest. Families grow ａｎｄ　change with children arriving, growing up ａｎｄ　leaving home. The house ofthe future will have to grow ａｎｄ　change with the familyF, nothing will be as fixed as it is now. The house will always be changing to meet changing needs. Everyone agrees that in thirty years\' time we will be living in "intelligent" houses. We will be able to talk to our kitchen machines ａｎｄ　discuss with them what to do. Like this, "we\'ll be having a party this weekend. What food shall we cook?" ａｎｄ　the machine will tell us what food we will have to buy ａｎｄ　how to cook it. We will be able to leave most of the cooking to the machines, just tasting things from time to time to check. The house of the future will be personal-each house, ______, you won\'t have to paint them, you\'ll be able to tell the wall to change the color! ａｎｄ　if you don\'t like the colｏｒthe next day, you will be able to have a new one. The only thing you won\'t be able to do is moving the house somewhere else.【单选题】

A.you will be able to change the colｏｒofthe wall easily

B.The only thing you won\'t be able to do is moving the house somewhere else

C.ａｎｄ　the machine will tell us what food we will have to buy ａｎｄ　how to cook it

D.what our home will be likeE

E.The house ofthe future will have to grow ａｎｄ　change with the familyF

F.he kids might take their bedrooms with them as they have

正确答案:A

答案解析:意思是“要改变墙体的颜色非常容易”，与下文中改变墙体颜色相关。

2、In the process, the light energy converts to heat energy.【单选题】

A.reduces

B.changes

C.leaves

D.drops

正确答案:B

答案解析:在这个过程中，光能转化成热能。本题难度不大，converts指“转变”，通常与to或者into搭配，和changes“变化”是近义词，其他三项都是常用词，和答案意义差异较大，干扰性不强。

3、I\'d very much like to know what your aim in life is.【单选题】

A.thought

B.idea

C.goal

D.plan

正确答案:C

答案解析:我很想知道你的人生目标是什么。本题有一定难度，虽然选项都是常用词汇，但干扰项干扰较大。aim和goal都有“目标”的意思，是近义词，A项指“思想”，B项指“想法”，D项指“计划”，最佳答案是C。

4、Radiocarbon DatingNowadays scientists can answer many questions about the past through a technique called radiocarbon (放射性碳), ｏｒcarbon - 14 dating. One key to understanding how ａｎｄ　why something happened is to discover when it happened.Radiocarbon dating was developed in the late 1940s by physicist Willard F. Libby at the University of Chicago. An atom of ordinary carbon, called carbon -12, has six protons (质子) ａｎｄ　six neutrons (中子) in its nucleus (原子核). Carbon - 14, ｏｒC - 14, is a radioactive, unstable form of carbon that has two extra neutrons. It returns to a more stable form of carbon through a process called decay (衰减). This process involves the loss of the extra neutrons ａｎｄ　energy from the nucleus.In Libby\'s radiocarbon dating technique, the weak radioactive emissions(放射)from this decay process are counted by instruments such as a radiation detectｏｒａｎｄ　counter. The decay rate is used to determine the proportion of C -14 atoms in the sample being dated.Carbon - 14 is produced in the Earth\'s atmosphere when nitrogen(氮) - 14, ｏｒN - 14, interacts with cosmic rays (宇宙射线). Scientists believe since the Earth was formed, the amount of nitrogen in the atmosphere has remained constant. Consequently, C -14 formation is thought to occur at a constant rate. Now the ratio of C -14 to other carbon atoms in the atmosphere is known. Most scientists agree that this ratio is useful fｏｒdating items back to at least 50,000 years.All life on Earth is made of organic molecules (分子) that contain carbon atoms coming from the atmosphere. So all living things have about the same ratio of C -14 atoms to other carbon atoms in their tissues (组织). Once an organism (有机体) dies it stops taking in carbon in any form, ａｎｄ　the C -14 already present begins to decay. Over time the amount of C - 14 in the material decreases ａｎｄ　the ratio of C - 14 to other carbon atoms goes down. In terms of radiocarbon dating, the fewer C -14 atoms in a sample, the older that sample is.Radar is used to determine the characteristics of radiocarbon.【单选题】

A.Right

B.Wrong

C.Not mentioned

正确答案:C

答案解析:本题有较大难度，答案依据不明显，需要通读全文作出判断。通读全文后可以发现文章并未提及使用雷达来进行放射性碳测定，所以本题是未提及的，答案是C。

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 colｏｒswitching material. It will turn red before a structure collapses ｏｒfalls apart. The secret behind the colｏｒswitching material is a particular type of molecule. A molecule is aｇｒｏｕｐof atoms held together by chemical bonds. Molecules come at 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 colｏｒswitching 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" 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 colｏｒswitching polymers in their lab. The test results proved encouraging. There is a way to get rid of the colｏｒlight when a bright light is shone on the mechanophore. The broken bond is fixed ａｎｄ　the red colｏｒdisappears. This "self-healing" may be a problem fｏｒengineers. They need to use the colｏｒchanger 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 colｏｒswitching molecules can be used outside the lab. 【单选题】

A.closes

B.breaks

C.increases

D.bums

正确答案:B

答案解析:前文为bond，意为联系，后文说到变红，说明不是在常态之下，那么联系是常态，联系断开才与红相对应，所以选break。
