1、We had a long conversation about her parents.【单选题】

A.speech

B.question

C.talk

D.debate

正确答案:C

答案解析:关于她父母我们谈了很久。本题难度不大，考查的是基本意义，干扰项干扰不大。conversation和talk都有“谈话”的意思，是近义词，A．项指“讲话”，D项指“辩论”，和答案意义差异大，最佳答案是C。

2、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.The goal of the creation of the EOL is to ______.【单选题】

A.collect enough data to analyze the living species on Earth

B.work out an easy -to - use catalog of every living species on Earth

C.enlarge an existing Web site of the living species on Earth

D.add new information to the existing ｄａｔａｂａｓｅs of the living species on Earth

正确答案:B

答案解析:本题有一定难度，需要读懂句意。带着题干信息词回文章定位，答案依据主要在文章第二段后面两句：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.谈到了物种百科网站创建的目的，回来看选项，B项和原文句意相近，是答案。

3、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, what 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 _____ vials (小药瓶). ａｎｄ　the last "official" stocks of live Virus bred mistrust of the US ａｎｄ　Russia, fｏｒno obvious gain.Now American researchers have found an animal model of the human disease, opening the way fｏｒtests 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.more

B.few

C.a few

D.a lot

正确答案:C

答案解析:本题有一定难度，本题可用排除法，文章里没有出现比较的含义，所以more可以排除掉，a lot后面不能接名词，不能说a lot vials，所以也可以排除掉，依据上下文逻辑，文章此处是说“毫无疑问，几个国家仍有几瓶（病毒）”，此处要用“几个”的意思，只能用a few，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 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 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 ______, 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.inside

B.beside

C.outside

D.above

正确答案:C

答案解析:本题有一定难度，但干扰项干扰不大，关键在理解好文章上下文意义，文章此处是说，“工程师需要把这种变色装置用在大型建筑项目上，用在外面，在阳光下”，答案是C。

5、The company has the right to end his employment at any time.【单选题】

A.provide

B.stop

C.offer

D.continue

正确答案:B

答案解析:公司有权利可随时终止与他的雇佣关系。本题难度不大，end是常用词，此处是动词，指“结束”，和stop“停止”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。答案是B。
