Question

阅读理解 　　A team of American engineers is studying the feasibility(可行性)of a nuclearpowered mission to the outer edges of the solar system．The target is Neptune, the eighth planet from the sun, and its icy moons． 　　The answer is a huge spacecraft driven by a compact nuclear reactor．It could drop a series of probes(探测器)into Neptune's atmosphere and help answer questions about the birth of the solar system． 　　If it gets U．S．National Aeronautics and Space Administration's(NASA)blessing, the Neptune orbiter could be launched around 2016 and arrive in Neptune around 2035． 　　The project is led by U．S．aircraft manufacturer Boeing and backed by NASA．A twelve－month study of what one scientist calls“the ultimate in deep space exploration”has already begun． 　　Neptune is a gas giant and sometimes the most distant of the nine planets in the solar system． 　　It has 11 known moons．The biggest, Triton, is bigger than the sun's ninth planet, Pluto．No spacecraft has been near Neptune since NASA's Voyager 2 sped past it in 1989． 　　Profound(深奥的)Questions 　　The Neptune mission is one of 15 competitive for commitment from the U．S．space a gency．Its proposers say the journey could answer profound questions．Because it is one of the most distant members of the sun's planets, Neptune's fabric is more likely to match the original materials of the solar system． 　　“Neptune is a rawer planet．”said Paul Steffes of the Georgia Institute of Technology． 　　“It is less influenced by near－sun materials and it is more representative of the original solar system than Jupiter or Saturn．”he added． 　　Neptune is a puzzle．It is roughly 30 times the distance from the sun as the earth is．It has seasons, and winds whip across its gaseous surface at 1,500 kilometres per hour． 　　Triton, too, poses riddles．It may not be a natural child of Neptune：It may have been a passing comet from a far－away region called the Kuiper belt captured and imprisoned byNeptune's powerful gravitational field． (1) Neptune ________． [　　] A． is a gas planet B． is farther than the other eight planets from the sun C． has 11 moons all together D． has four seasons every year (2) The plan to explore Neptune ________． [　　] A． was suggested by NASA B． is to help to learn about how the solar system came into being C． will be carried out in 12 months D． is mainly to test if people can live in Neptune in the future (3) According to the text, there is no doubt that Triton ________． [　　] A． travels around Neptune B． is bigger than the sun's nine planets C． belongs to Neptune since it was born D． is a passing comet from the Kuiper (4) We can know from the text that ________． [　　] A． Voyager 2 got close to Neptune in 1989 B． material of Neptune is the same as that of the solar system C． it's very cold on Neptune's moons D． Neptune is too far－away from us to be studied (5) What's the author's attitude towards the Neptune mission? [　　] A． He doubts whether it can be completed by 2035． B． He thinks it's a waste of money to do such a meaningless job． C． He believes that modern technology is not advanced enough to do so． D． He is full of hope that it will come true in the near future．

Answer 1

答案：1．A;2．B;3．A;4．C;5．D;
解析：

(1)	依据：Neptune is a gas giant and sometimes the most distant of the nine planets in the solar system．海王星是一个巨大的气体星球．a gas giant一个巨大的气体．
(2)	依据：It could drop a series of probes into Neptune's atmosphere and help answer questions about the birth of the solar system．(about the birth of the solar system关于太阳系的诞生)，根据分析可知探测海王星是为了了解太阳系的形成原因．drop a series of probes留下一系列的探索/调查．
(3)	依据：The biggest, Triton, is bigger than the sun's ninth planet, Pluto, Triton比太阳的第九颗行星(冥王星)还大．前一句提到海王星有11个已知卫星，本句又指出Triton比冥王星大，再联系地球与月球之间的关系即可确定A项正确．
(4)	依据第一段中的“The target is Neptune, the eighth planet from the sun, and its moon．”和倒数第二段中的“and winds whip across its gaseous surface at 1,500 kilometres per hour．”可知C项正确．gaseous surface“气体的表面”；target“目标”．
(5)	根据①A team of American engineers is studying the feasibility of a nuclear－powered mission to the outer edges of the solar system．②The answer is a huge spacecraft driven by a compact nuclear reactor．可知作者认为利用核动力去探测海王星是可取的，所以作者对此充满了希望．nuclear－powered“核动力的”；compact nuclear reactor“密集核反应器”．
