Question

【题目】 You get into an elevator(电梯). There is a button(按钮) inside. You press the button. Then the elevator takes you to outer space. Does this sound like something from a scifi movie? In fact, it might become real in the future.

Scientists hope to build the space elevator by 2050, Science Daily reported. The elevator might look like an egg. It can carry 30 people. The trip is about 36，000 km and it may take eight days to get into space. And the elevator has a cable(缆绳). The cable is very important for the elevator. It should be very strong so that it can stand up to the high pressure(高压). The cable connects the elevator to the International Space Station and the elevator goes up and down along the cable.

People can only go into space by spacecraft or rocket right now. But they are expensive. A space elevator would be much cheaper. It can do more than just take people into space. The elevator can also send heavy things or scientific materials(材料) into space. However, one difficult part of building a space elevator now is finding the right material for the cable. And scientists are still working hard on it.

【1】In Paragraph 2, the underlined word “It” may refer to “the ________”.

A.cableB.rocket

C.spacecraftD.space elevator

【2】From the passage, we can know that the space elevator ________.

A.looks like a big footballB.comes from a scifi movie

C.needs 30 scientists to buildD.can take people into space

【3】The scientists want to build a space elevator probably because it can ________.

A.carry the spacecraft or the rocket

B.send more materials into space

C.help find more ways to other planets

D.make space travel less expensive

【4】According to the passage, building a space elevator is ________.

A.easy and funB.difficult but possible

C.hard and boringD.useful but impossible

Answer 1

【答案】

【1】A

【2】D

【3】D

【4】B

【解析】

短文讲了未来的太空电梯，详细介绍了电梯的结构，功能，以及和火箭的区别。

【1】词意猜测题。根据And the elevator has a cable(缆绳). The cable is very important for the elevator. It should be very strong so that it can stand up to the high pressure(高压).可知，电缆对电梯很重要。电缆应该非常坚固，这样才能承受高压。It指代的是上文的电缆，故选A。

【2】细节理解题。根据People can only go into space by spacecraft or rocket right now. But they are expensive. A space elevator would be much cheaper. It can do more than just take people into space.可知，现在人们只能乘坐宇宙飞船或火箭进入太空。但是它们很贵。太空电梯会便宜很多。它能做的不仅仅是把人送入太空。故天空电梯能把人送入太空，故选D。

【3】细节理解题。根据People can only go into space by spacecraft or rocket right now. But they are expensive. A space elevator would be much cheaper.可知，科学家们想要建造一个太空电梯可能是因为通过太空电梯进入太空要便宜的多。故选D。

【4】推理判断题。根据However, one difficult part of building a space elevator now is finding the right material for the cable. And scientists are still working hard on it.可知，建造太空电梯是困难的，但是找到合适的电缆材料，建造太空电梯就是有可能的。故选B。
