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(擴(kuò)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 (隕石).
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.

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 本文屬于說(shuō)明文閱讀,作者通過(guò)這篇文章主要向我們描述了太空服的進(jìn)化問(wèn)題,保護(hù)一個(gè)人對(duì)于空間環(huán)境的危險(xiǎn)是很重要的.
解答 32.C.細(xì)節(jié)理解題.根據(jù)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."可知沒(méi)有提到的因素是身體內(nèi)的氣體,故選C.
33.B.推理判斷題.根據(jù)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."可知身著早期的宇航服,宇航員不能移動(dòng),做任務(wù),并且不能安全舒適地停留在太空船之外.故選B.
34.C.詞義猜測(cè)題.根據(jù)It was designed to endure longer and to permit more movement than earlier spacesuits聯(lián)系下文"longer"可知此處指的是持續(xù)的時(shí)間更長(zhǎng),故選C.
35.D.主旨大意題.閱讀短文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可知這篇短文主要講述了太空服的演化問(wèn)題.故選D.
點(diǎn)評(píng) 考察學(xué)生的細(xì)節(jié)理解和推理判斷能力,做細(xì)節(jié)理解題時(shí)一定要找到文章中的原句,和題干進(jìn)行比較,再做出正確的選擇.在做推理判斷題不要以個(gè)人的主觀想象代替文章的事實(shí),要根據(jù)文章事實(shí)進(jìn)行合乎邏輯的推理判斷.
