6.When thinking about placing a human being in space,one of the most important questions was how to design special clothing needed to protect a person from the dangers of the space environment.The cold of space will freeze skin in a short time.The fierce heat of the sun can cause serious burns.The lack of atmosphere can cause gases in the body to expand(扩大) and even burst.With no oxygen to breathe,a human being will die in only a few moments.Radiation from the sun is another risk in space.So is damage from small pieces of rock and objects like meteoroids (陨石).In 1933,an American flyer,Wiley Post,designed one of the first successful devices to protect a pilot at extreme heights.It was a large device that looked like a can surrounded the pilot's head.Astronauts in the American space agency (NASA) flew the first American space flights in the early 1960s.The clothing was similar to that invented by Wiley Post.
Today,astronauts wear very different protective clothing.It lets them move,do useful tasks,and stay outside their spacecraft in comfort and safety for several hours.The spacesuit is called the shuttle extravehicular mobility unit or EMU.It was designed to endure longer and to permit more movement than earlier spacesuits.
The EMU has a number of parts that an astronaut can link together by using only one hand,which makes it possible for each astronaut to select the parts that fit correctly.
Nowadays,NASA scientists are also considering the kind of spacesuits that would be needed for exploration on the planet Mars.Because of the gravity on Mars,spacesuits may have to be designed to be lighter than suits used in orbit or on the moon.The equipment may also have to protect astronauts from dust carried in the winds on Mars.And,they must be easy to repair and keep clean during a longer flight to and from the red planet.
32.Which of the following is NOT mentioned about the dangers of space environment?C
A.Lack of oxygen.
B.Fierce heat from the sun.
C.Gases in the body.
D.Radiation from the sun.
33.Which of the following statements is true,according to this passage?B
A.Wiley Post designed the first protective clothing for astronauts.
B.Astronauts in earlier spacesuits had difficulty in moving,doing useful tasks and so on.
C.EMU has many parts that can be linked together by using two hands.
D.Special spacesuits have been used for exploration of the planet Mars.
34.The underlined word"endure"meansC.
A.provide B.move C.last D.live
35.The best title of the passage might beD.
A.Space explorationB.Astronauts'flights
C.The Advantages of Spacesuits D.The Development of Spacesuits.
分析 本文属于说明文阅读,作者通过这篇文章主要向我们描述了太空服的进化问题,保护一个人对于空间环境的危险是很重要的.
解答 32.C.细节理解题.根据短文第一段"The cold of space will freeze skin in a short time.…Radiation from the sun is another risk in space."可知没有提到的因素是身体内的气体,故选C.
33.B.推理判断题.根据短文第三段"Today,astronauts wear very different protective clothing.It lets them move,do useful tasks,and stay outside their spacecraft in comfort and safety for several hours."可知身着早期的宇航服,宇航员不能移动,做任务,并且不能安全舒适地停留在太空船之外.故选B.
34.C.词义猜测题.根据It was designed to endure longer and to permit more movement than earlier spacesuits联系下文"longer"可知此处指的是持续的时间更长,故选C.
35.D.主旨大意题.阅读短文When thinking about placing a human being in space,one of the most important questions was how to design special clothing needed to protect a person from the dangers of the space environment可知这篇短文主要讲述了太空服的演化问题.故选D.
点评 考察学生的细节理解和推理判断能力,做细节理解题时一定要找到文章中的原句,和题干进行比较,再做出正确的选择.在做推理判断题不要以个人的主观想象代替文章的事实,要根据文章事实进行合乎逻辑的推理判断.
