1、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."Spider" ａｎｄ　"bird" mentioned in Paragraph 1 are examples to illustrate ______.【单选题】

A.there are numerous living species on Earth

(资料图片)

B.animals are people\"s friends

C.it is easy to see spiders ａｎｄ　birds

D.here are many types of spiders ａｎｄ　birds

正确答案:A

答案解析:本题有一定难度，带着题干信息词回文章定位，答案依据主要在文章第一段：So far, scientists have named about l.6 million living species, ...it can be tough to figure out what type of spider is moving up your leg ｏｒwhat kind of bird is flying by.谈到了地球物种数量巨大，回来看选项，A项和原文句意相近，是答案。

2、Meet Your Memory1. Memory is something that cannot be seen, touched ｏｒweighed. It is thought to be abstract. It is a ｓｅｔof skills rather than an object. Neither is there a single standard fｏｒjudging a good ｏｒpoｏｒmemory. There are a number of different ways in which a person may have a good memory.2. Memory is generally viewed as consisting of three stages: (1) acquisition refers to learning the material; (2) storage refers to keeping the material in the brain until it is needed; (3) retrieval (提取) refers to getting the material back out when it is needed:3. Memory consists of at least two different processes: short - term memory ａｎｄ　long - term memory. Short - term memory has a limited capacity ａｎｄ　a rapid forgetting rate. Its capacity can be increased by chunking (组成大块), ｏｒgrouping separate bits of information into larger chunks. Long - term memory has an almost unlimited capacity.4. One measure of memory is recall, which requires you to produce information by searching the memory fｏｒit. In aided recall, you are given cues (提示) to help you produce the information. In free - recall learning you recall the material in any order. In serial learning you recall it in the ｏｒｃｅｒit was presented ａｎｄ　in paired - associate learning you learn pairs of words so that when the first word is given you can recall the second word. A second measure of memory is recognition, in which you do not have to produce the information from memory, but must be able to identify it when it is presented to you. In a third measure of memory, relearning, the difference between how long it took to learn the material the first time ａｎｄ　how long it takes to learn it again indicates how much you remember. Relearning is generally a more sensitive measure of memory than is recognition because relearning shows retention (保持) while recognition does not. Recognition is generally a more sensitive measure than recall.Paragraph 4 ______【单选题】

A.Why do we forget things?

B.How do we measure memory?

C.What are the stages memory consists of?

D.What is the difference between short - term memory ａｎｄ　long - term memory?

E.What is memory?

F.Who may have a poｏｒmemory?

正确答案:B

答案解析:本题有一定难度，没有明显的主旨句，需要较强归纳能力。文章第四段主要论述了测量记忆力的三种方法，回来看选项，B项How do we measure memory?简单概括了本段主要意思，是答案。

3、Shopping at Second - hａｎｄ　Clothing StoresWhen 33 year old Pete Barth was in college, shopping at second hａｎｄ　clothing stores was just something he did- "like changing the tires on his car." He looked at his budget ａｎｄ　decided he could save a lot of money by shopping fｏｒclothes at thrift shops."Even new clothes are fairly disposable (用后即丢掉的) ａｎｄ　wear out after a couple of years," Barth said. "In thrift shops, you can find some great stuff whose quality is better than new clothes."Since then, Barth, who works at a Goodwill thrift shop in the US state of Florida, has found that there are all kinds of reasons fｏｒshopping fｏｒsecond - hａｎｄ　clothing. Some people, like him, shop to save money. Some shop fｏｒa crazy - looking shirt. ａｎｄ　some shop as a mean conserving energy ａｎｄ　helping the environment.Pat Akins, an accountant at a Florida Salvation Army (SA) (救世军) thrift shop, said that, fｏｒher, shopping at thrift shops is a way to help the environment."When my daughter was little, we looked at it as recycling," Akins said. "Also, why pay 30 dollars fｏｒa new coat when you can get another one fｏｒa lot less?"Akins said that the SA has shops all over the US- "some as big as department stores. All of the clothes are donated (捐赠), ａｎｄ　when they have a surplus (盈余), they\"ll have" stuff a bag" specials, where customers can fill a grocery sack with clothes fｏｒonly 5 ｏｒ10 dollars.Julia Slocum, 22, points out, however, that the huge amount of second - hａｎｄ　clothing in the US is the result of American wastefulness."I\"d say that second - hａｎｄ　stores are the result of our wasteful, materialistic culture," said Slocum, who works fｏｒa pro - conservation organization, the center of a New American Dream. "Thrift shops prevent that waste from going to landfills (垃圾填埋场). They give clothing a second life, provide cheaper clothing fｏｒthose who can\"t afford to buy new ones ａｎｄ　generate (创造) income fｏｒcharities. They also provide a way fｏｒthe wealthy ａｎｄ　middle classes to shed (摆脱) the guilt fｏｒtheir level of consumption.Which statement about Barth is NOT true? ______【单选题】

A.He is 33 years old now.

B.He works at a Goodwill thrift shop.

C.He works at a Salvation Army thrift shop.

D.He was a college student many years ago.

正确答案:C

答案解析:本题难度较大，需要认真阅读文章，做出判断。认真阅读文章前三段。第一段第一句谈到了作者大学期间经常逛二手服装店，第三段第一句话谈到了作者在Goodwill旧货店工作，可以推断A，B，D项正确，所以答案是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 _____ 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.results

B.rules

C.tools

D.methods

正确答案:A

答案解析:本题难度不大，考查的是词义辨析。很明显，文章此处的意思是“结果”，答案是A。

5、How to Be a Successful BusinesspersonHave you ever wondered why some people are successful in business ａｎｄ　others are not? Here\"s a story about one successful businessperson. He started out washing dishes ａｎｄ　today he owns 168 restaurants.Zubair Kazi was born in Bhatkal, a small town in southwest India. His dream was to be an airplane pilot, ａｎｄ　when he was 16 years old, he learned to fly a small plane.At the age of 23 ａｎｄ　with just a little money in his pocket, Mr. Kazi moved to the United States. He hoped to get a job in the airplane industry in California. Instead, he ended up working fｏｒa company that rented cars.While Mr. Kazi was working at the car rental(租赁的) company, he frequently ate at a nearby KFC restaurant. To save money on food, he decided to get a job with KFC. Fｏｒtwo months, he worked as a cook\"s assistant. His job was to clean the kitchen ａｎｄ　help the cook. "I didn\"t like it," Mr. Kazi says, "but I always did the best I could."One day, Mr. Kazi\"s two co - workers failed to come to work.
