Question

【题目】“Hello, Earth! Can you hear me?” That’s voice more than 400,000 people received recently. It was from Philae, a space vehicle that landed on a comet(彗星)in 2014. However, its transmissions (传输信号)back home went silent since then.

It took a 1ong time for Philae to make its way across the solar system (太阳系)and reach comet 67P/C-G. The pace vehicle got there aboard the Rosetta probe (探测器), which has been circling around the comet since Philae separated from it in November, 2014．

Philae’s job was to collect materials to study the comet’s composition. And for about two and a half days after landing, it did just that, sending the information back to scientists on Earth. But Philae’s landing on the comet’s icy surface had not been smooth. While touching down, it jumped up and ended up in the shadow of something like a huge rock. Philae runs on solar power, but there was no light in the place where it landed. In the end, it failed to work.

However，as comet 67P/C-G moved closer to the sun, more sunlight reached the space vehicle, allowing it to power up and come back online. Philae then sent something to Rosetta, which passed on the information back to Earth.

“We only received the information for about 85 seconds, but that’s enough to let us know it is alive and well,”says Stephan Ulamec, who works for the European Space Agency.“We hope to work out where it landed exactly on the 4-kilometer-wide comet. Now we plan to change how Rosetta moves so that Philae can keep on communicating and receiving instructions.”

【1】Hearing Philae’s voice，those people must have felt_______________.

A. afraid B. calm

C. excited D. worried.

【2】According to the text, Philae_______________.

A. was damaged when it landed

B. moved around comet 67P/C-G

C. needs light and gas to keep working

D. helps scientists learn about a comet

【3】What Stephan says in the text suggests that ____________.

A. Rosetta will move around another comet

B. Philae will continue to work for scientists

C. most comets are as wide as four kilometers

D. he wonders whether Philae is still alive

【4】What does the author mainly talk about in the text?

A. A sleeping space vehicle wakes up．

B. It is very dangerous to travel in space.

C. A new comet was discovered recently.

D. Philae was sent into space successfully.

Answer 1

【答案】

【1】C

【2】D

【3】B

【4】A

【解析】本文是说明文。向我们讲述了彗星着陆器Philae在2014年在失联后又重新得到它的消息，告诉全世界它活的很好。现在科学家现在计划如何变化，使Philae能够保持罗塞塔移动通信，接收指令。

【1】推理判断题。由第一段中的Philae ... landed on a comet in 2014. However, its transmissionsback home went silent since then可知，Philae于2014年着陆彗星后就失联了，所以当人们再次听到它传来的声音时一定很兴奋，故选C项。

【2】细节理解题。由第三段中的Philae's job was to collect materials to study the comet's composition可知，Philae的任务是帮助科学家了解一颗彗星的相关情况，故选D项。

【3】细节理解题。由最后一段中的Now we plan to change how Rosetta moves so that Philae can keep on communicating and receiving instructions可知，Philae将会继续服役，故选B项。

【4】主旨大意题。总览全文可知，文章主要介绍了彗星着陆器Philae的一些情况。它在沉睡了好久之后醒了过来，并向地球发回了信息。故选A。
