9."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 85seconds,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 feltC.
A.afraid B.calm C.excited D.worried.
26.According to the text,PhilaeD.
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 thatB.
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.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.
分析 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.
解答 25.C.推理判断题.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.
26.D.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.
27.B.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会继续为科学家们工作,故选B.
28.A.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.
点评 考查学生的细节理解和推理判断能力.做细节理解题时一定要找到文章中的原句,和题干进行比较,再做出正确选择.在做推理判断题时不要以个人的主观想象代替文章的事实,要根据文章事实进行合乎逻辑的推理判断.
