2、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 ______ 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 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 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.why
B.how
C.what
D.where
正确答案:C
答案解析:本句的意思是分子的行为取决于组合成分子的原子种类和它们的组合方式。所以kind前应加what。
3、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 word "novice" in Paragraph 5 could be best replaced by ______.【单选题】
A.scientist
B.creator
C.beginner
D.expert
正确答案:C
答案解析:本题难度较大,需要很强的把握词义能力。本题可以先看选项得到信息提示,也可以结合原文的提示: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…,可以看出,novice的意思和basic相近,和expert相反,回来看选项,C项和原文句意相近,是答案。
4、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。
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 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。
