Question

4．Washington：NASA has announced evidence that Jupiter's largest moon，Ganymede，has a saltwater ocean under its icy surface．The ocean seems to have more water than all the water on Earth's surface，according to new Hubble observation．
New Hubble observations of Ganymede's magnetic field strongly suggest that the moon，which is the largest in our whole solar system，is home to a subsurface ocean．
Scientists estimate the ocean is 95 kilometres thick，which is about 10 times deeper than Earth's oceans．But unlike our salty waters，Ganymede's ocean is buried under 150 kilometres of ice．
While scientists have speculated（推测） since 1970s about the presence of an ocean on Ganymede-the largest moon in our solar system-until now the only observational evidence came from a brief flyby by the Galileo spacecraft，which didn't observe the moon long enough to confirm a liquid ocean．
This discovery marks an important milestone，highlighting what only Hubble can accomplish．In its 25 years in orbit，Hubble has made many scientific discoveries in our own solar system．A deep ocean under the icy surface of Ganymede opens up further exciting possibilities for life beyond Earth．
Scientists_have_already_confirmed_the_existence_of_an_ocean_on_Europe，_another moon orbiting Jupiter，and NASA has announced plans to send an unmanned mission there searching for the life that might come with liquid water．
Hubble is a telescope that orbits Earth，but because of its impressive gravitational analyses it can be used to study the inside of far distant planets．Using these same principles，scientists could theoretically detect oceans on distant planets as well．
25．What can we learn about the Ganymede from the passage？C
A．It is a planet with the largest moon in our whole solar system．
B．It will be used by NASA as a base for the Hubble telescope．
C．Its ocean adds to people's excitement about life beyond Earth．
D．Its liquid ocean was first proved by the Galileo spacecraft．
26．Which of the following best describes the writer's attitude towards Hubble？
A
A．Favorable．B．Doubtful．
C．Negative．D．Cautious．
27．What does the underlined part in Paragraph 6 mean？B
A．An underground ocean has been found in Europe．
B．It is now certain that there is an ocean on Europe．
C．The presence of an underground ocean in Europe is not possible．
D．No evidence has shown the existence of an ocean on Europe．
28．What type of writing does this passage belong to？D
A．A term essay．
B．An exploration review．
C．An experiment report．
D．A news report..

Answer 1

分析 本文属于说明文阅读，作者通过这篇文章主要向我们描述了海洋增加了人们关于地球以外的生命的兴奋，科学家们推测海洋对生命至关重要．

解答 25．C．细节理解题．根据通过第五段中"A deep ocean under the icy surface of Ganymede opens up further exciting possibilities for life beyond Earth．"可知海洋增加了人们关于地球以外的生命的兴奋．故选C．
26．A．推理判断题．Cautious谨慎的； Doubtful怀疑的； Negative否定的； Favourable支持的．根据通过第五段中"This discovery marks an important milestone，highlighting what only Hubble can accomplished．"可知作者对Hubble的态度是支持的．故选A．
27．B．句意理解题．通过横线句子中的"confirm the existence"和"NASA has announced plans to send an unmanned mission there searching for the life that might come with liquid water．"可知欧洲上空可能有海洋是确定的．故选B．
28．D．推理判断题．term essay一个学期论文；A news report一个新闻报道；An experiment report 一个实验报告；An exploration review一个探索评论．通过第一段"Washington：NASA has announced evidence…"格式及文章内容可知．故选D．

点评 考察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，再做出正确的选择．在做推理判断题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．
