Question

【題目】根據(jù)短文理解，選擇正確答案。
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.
（1）Which of the following is NOT mentioned about the dangers of space environment?
A.Lack of oxygen.
B.Fierce heat from the sun.
C.Gases in the body.
D.Radiation from the sun.
（2）Which of the following statements is true, according to this passage?
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.
（3）The underlined word “endure” means _______.
A.provide
B.move
C.last
D.live
（4）The best title of the passage might be ______.
A.Space exploration
B.Astronauts' flights
C.The Advantages of Spacesuits
D.The Development of Spacesuits

Answer 1

【答案】
（1）C
（2）B
（3）C
（4）D
【解析】文章主要介紹了太空服的發(fā)展歷程。人類進入太空所要面對的重要問題之一便是怎樣設(shè)計出能夠抵擋太空惡劣環(huán)境的防護服。早期的太空服給宇航員的行動和執(zhí)行任務(wù)帶來不便，現(xiàn)在的太空服已經(jīng)能夠讓宇航員行動自如。

（1）C細節(jié)理解題。根據(jù)首段“The cold of space... The fierce heat of the sun ...The lack of atmosphere...With no oxygen to breathe...Radiation from the sun...So is damage from small pieces of rock and objects like meteoroids (隕石).”可知，A、B、D都是太空環(huán)境潛在的危險，故選C。

（2）B推理判斷題。根據(jù)第二段“It was a large device that looked like a can surrounded the pilot's head...the first American space flights in the early 1960s. The clothing was similar to that invented by Wiley Post.”可知，首次太空之旅所用的防護服與Wiley Post發(fā)明的裝置相似，說明不是Wiley Post發(fā)明了第一代防護服，排除A；根據(jù)第四段“The EMU has a number of parts that an astronaut can link together by using only one hand”可知，宇航員用一只手就可以很方便地操作EMU，排除C；根據(jù)第五段“Nowadays, NASA scientists are also considering the kind of spacesuits that would be needed for exploration on the planet Mars”可知，特制的太空服尚未用于火星探索，排除D；根據(jù)第三段“...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，以前的太空服不能讓宇航員行動自如，也不便于執(zhí)行任務(wù)，而現(xiàn)在的太空服能夠做到這些，故選B。

（3）C猜測詞義題。endure longer和permit more movement是并列關(guān)系，兩者都是與以前的太空服相比，EMU具有的優(yōu)勢，即EMU的設(shè)計出發(fā)點是更持久、行動更自如，故選C。

（4）D選擇最佳標題。文章首段“one of the most important questions was how to design special clothing”就提到了怎樣設(shè)計特殊的太空服這一問題，第二段提到了早期的太空服，第三段和第四段介紹了現(xiàn)代的太空服，第五段對未來的太空服提出了設(shè)想，由此可知，文章主要講的是太空服的發(fā)展，故選D。
