Question

【題目】“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 (傳輸信號)back home went silent since then.

It took a 1ong time for Philae to make its way across the solar system (太陽系)and reach comet 67P/C-G. The pace vehicle got there aboard the Rosetta probe (探測器), 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】本文是說明文。向我們講述了彗星著陸器Philae在2014年在失聯(lián)后又重新得到它的消息，告訴全世界它活的很好�，F(xiàn)在科學(xué)家現(xiàn)在計劃如何變化，使Philae能夠保持羅塞塔移動通信，接收指令。

【1】推理判斷題。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年著陸彗星后就失聯(lián)了，所以當(dāng)人們再次聽到它傳來的聲音時一定很興奮，故選C項。

【2】細(xì)節(jié)理解題。由第三段中的Philae's job was to collect materials to study the comet's composition可知，Philae的任務(wù)是幫助科學(xué)家了解一顆彗星的相關(guān)情況，故選D項。

【3】細(xì)節(jié)理解題。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將會繼續(xù)服役，故選B項。

【4】主旨大意題�？傆[全文可知，文章主要介紹了彗星著陸器Philae的一些情況。它在沉睡了好久之后醒了過來，并向地球發(fā)回了信息。故選A。
