Question

                           B 

        Hello,Earth!Can you hear me?” That's the voice more than 400,000 people received recently. It was from Philae,a space vehicle that landed on a comet in 2014. However its transmissions(傳送信號) back home went silent since then.

        It took a long time for Philae to make its way across the solar system and reach comet 67P/C-G. The space vehicle got there aboard the Rosetra 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."

25. Hearing Philae’ s voice,those people must

have felt .

   A. afraid   B. calm

   C. excited   D. worried

26. 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

27. 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

28. 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 snrnpcsfiillv

Answer 1

25.C 26. D 27. B 28. A

25.C. 推理判斷題。由第一段中的 Philae ... landed on a comet in 2014. However,its transmissions back 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。

26. D.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,的任務(wù)是幫助_學(xué)家了解 一顆彗星的相關(guān)情況，故選D項。

27. B.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，/VwYfle將會繼續(xù)服役，故選B項。

28. A.主旨大意題。總覽全文可知，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。
