1、Snow RangerThe two things, snow ａｎｄ　mountains, which are needed fｏｒa ski area are the two things that cause avalanches, large mass of snow ａｎｄ　ice crushing down the side of a mountain, often called "White Death. "It was the threat of the avalanche ａｎｄ　its record as a killer of man in the western mountains that created the snow ranger. He first started on avalanche control work in the winter of 1937, 38 at Alta, Utah, in Wasatch National Forest. This mountain valley was becoming well known to skiers. It was dangerous. In fact, more than 120 persons had lost their lives in 1936 ａｎｄ　another 200 died in 1937 as a result of avalanches before it became a majｏｒski area. Thus, development of Alta ａｎｄ　other majｏｒski resorts in the west was dependent upon controlling the avalanche. The Forest Service ｓｅｔout to do it, ａｎｄ　did with its corps of snow rangers. It takes many things to make a snow ranger. The snow ranger must be in excellent physical condition. He must be a good skier ａｎｄ　a skilled mountain climber. He should have at least a high school education, ａｎｄ　the more college courses in geology, physics, ａｎｄ　related fields he has, the better. He studies snow, terrain, wind, ａｎｄ　weather. He learns the conditions that produce avalanches. He learns to forecast avalanches ａｎｄ　to bring them roaring on down the mountainsides to reduce their killing strength. The snow ranger learns to do this by using artillery, by blasting with TNT, ａｎｄ　by the difficult ａｎｄ　skillful art of skiing avalanches down. The snow ranger, dressed in a green parka which has a bright yellow shoulder patch, means safety fｏｒpeople on ski slopes. He pulls the trigger on a 75 mm. Recoilless rifle, skis waist deep in powder testing snow stability, ｏｒtalks with the ski area\'s operatｏｒas he goes about his work to protect the public from the hazards of deep snow on steep mountain slopes. What is the primary duty of the snow ranger?【单选题】

A.To make sure ski area operators are following safety rules.

B.To predict ａｎｄ　control avalanches in mountainous areas.

C.To check skis ａｎｄ　repair them.

D.To forecast the weather.

正确答案:B

答案解析:A:确保滑雪场地的操作员遵守安全规则；B：预测和控制山区的雪崩；C：检查并修理雪橇；D:预测天气。依据常识和前一题判断B最合理。

2、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 a few 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 _____ 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.need

B.time

C.fact

D.case

正确答案:D

答案解析:本题有一定难度，考查in case的用法，in case指“以免，以防”，文章此处是说“……以免这种病毒卷土重来”，答案是D。

3、You must shine your shoes. 【单选题】

A.lighten

B.clean

C.wash

D.polish

正确答案:D

答案解析:shine:使光亮，和polish（擦亮）意思相近；lighten:减轻（负担）、缓和、使轻松；wash:洗；clean:使干净。

4、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。

5、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.Grouping bits of information into larger chunks helps improve the capacity of our ______.【单选题】

A.short - term memory

B.relearning

C.needed

D.coded

E.recognition

F.slow forgetting rate

正确答案:A

答案解析:本题难度不大，答案依据比较明显，主要在第三段第三句：Its capacity can be increased by chunking…其中，Its capacity指的就是short - term memory的容量，回来看选项，A项short - term memory符合原文句意，是答案。
