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. A snow ranger himself must be____. 【单选题】

A.a college graduate.

B.a physicist.

C.a geologist.

D.a mountaineer.

正确答案:D

答案解析:A：大学毕业生；B：物理学家；C：地质学家；D：登山运动员。依据常识，D最合理。如果依据原文，文章第5段首句说“要成为雪地管理员需要很多的条件”，所以判断答案相关句应在该段中。该段说“雪地管理员应是优秀的登山运动员”，所以答案是D。

2、A special educationVideodisc holds great promise of helping to meet the needs of American schoolchildren who have problems seeing, hearing, speaking, ｏｒsocializing. Almost eleven percent of the students aged 3-21 in this country have an impairment that affects their ability to benefit from a regular education program. Handicapped students require special education because they are often markedly different from most children in one ｏｒmore of the following ways: mentally retarded (发展迟缓的) learning-disabled, emotionally disturbed, deaf, visually handicapped, physically handicapped, ｏｒother health impairments. The education of these handicapped children is rewarding but challenging. A special education student usually needs a longer period of time to acquire information. Repetitive teaching techniques are often beneficial, ａｎｄ　indefatigable (孜孜不倦) consistency on the part of the teacher is frequently necessary. Interactive videodisc courseware has characteristics that can be capitalized upon to meet the challenges that special education poses. A videodisc program is infinitely patient. Repetition of any videodisc lesson can continue endlessly, ａｎｄ　designers can assure absolute consistency within a program. Most important, according to special educatｏｒWilliam Healey of the University of Arizona, is that videodisc "adds an extra dimension of realism fｏｒchildren who need graphic representations."Healey explained that deaf ａｎｄ　mentally retarded children especially have difficulty grasping figurative language ａｎｄ　higher-ｏｒｃｅｒlanguage concepts. He believes that fｏｒspecial education, the power of videodisc lies in the ability of the technology to visually represent language concepts normally taken fｏｒgranted by non-handicapped persons. Complex figurative language forms such as idioms ａｎｄ　metaphors come most readily to mind as being difficult fｏｒhandicapped learners. According to ProfessｏｒHealey, we may infer that mentally retarded children perhaps____【单选题】

A.need graphic representations in ｏｒｃｅｒto understａｎｄ　higher-ｏｒｃｅｒlanguage concepts

B.are good at studying English idioms but often fail to grasp higher-ｏｒｃｅｒlanguage concepts

C.are not very patient with videodisc which helps them to understａｎｄ　the world concepts

D.tend to be deaf as well ａｎｄ　have difficulty learning the simple concept "before ａｎｄ　after"

正确答案:A

答案解析:文章第3段前两句指出，希利教授解释说耳聋和智力发展迟缓的孩子很难明白比喻性的话语和较为复杂的语言概念，所以他们需要直观的图解，而影碟能够帮助他们，由此推断A正确。

3、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 _____ 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 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.on

B.behind

C.under

D.down

正确答案:B

答案解析:本题有一定难度，干扰项干扰较大，考查介词behind的用法，文章此处是说，“材料颜色可以变化其背后的秘密是……”，只有behind可以表示“背后的”意思，答案是B。

4、While we don\'t agree, we continue to be friends.【单选题】

A.Whoever

B.Where

C.Although

D.Whatever

正确答案:C

答案解析:题干大意：虽然我们意见不同，但是我们仍然是朋友。画线词while引起的是一个让步从句，所起的作用是跟although一样的。whoever：无论任何人。where：哪里。如：Where are you from? 你从哪里来？whatever：无论什么。

5、Some Unusual CelebrationsSome holidays are well - known all around the world. Among them are New Year\'s Eve celebrations. Also common are days in honｏｒof love ａｎｄ　friendship, like Valentine\'s Day. Each country has its own special holidays too, often to mark important events in its history. Schools, banks ａｎｄ　government offices all close on days like these. Some of the days people celebrate, however, are less serious. A few of them are really very strange.Of course, they are not strange to the people who celebrate them. Perhaps that is because the celebrations have long traditions. Consider April Fool\'s Day, fｏｒexample. No one knows when ｏｒwhy it began. Today it is celebrated in many countries—France, Englａｎｄ　ａｎｄ　Australia, among others. On this day, people play practical jokes. Jokes are supposed to be funny, but these jokes do not make everyone laugh. The ones who laugh are the ones playing the jokes. The people they fool often get angry. Does celebrating this day make sense to you?Dyngus Day in Polａｎｄ　seems strange too. On this day, it is traditional fｏｒboys to pour water over the heads of girls. Here is the strangest part, they do it to girls they like.Other unusual celebrations take place in a single city ｏｒtown. A holiday called La Tomatina is celebrated in Bunol, Spain. Every year, in late August, big trucks carry more than 200,000 pounds of tomatoes into this little town. Then begins the world-s biggest food fight. Fｏｒtwo hours, people in the streets throw tomatoes at each other. Everyone ends up red from head to toe.August 10 marks the start of the Puck Fair, an Irish festival with a very unusual tradition. People from the town of Killorglin go up into the mountains ａｎｄ　catch a wild goat. _____There are also some celebrations that are really strange. In the United States, sometimes one person gets an idea fｏｒa new holiday ａｎｄ　tries to get others to accept it. Whose idea was Public Sleeping Day? That one is on February 28. It may seem strange, but it sounds like more fun than the one on February 29. That is supposed to be Toothache Day.Do you like the idea of inventing a new holiday? If you do, then you will want to mark March 26 on your calendar. That is Make Up Your Own Holiday Day.【单选题】

A.They bring him back to town, put a crown on his head, ａｎｄ　make him king fｏｒthree days.

B.Some of the days people celebrate, however, are less serious.

C.That is supposed to be Toothache Day.

D.Then begins the world-s biggest food fight.

E.Some people have fun imagining new holidays.

F.Jokes are supposed to be funny, but these jokes do not make everyone laugh.
