2. Question
题目分析
13道题目由三种题型组成：14-17是heading题，18-20是选择题，21-26是YES NO NOT GIVEN
个人倾向于这样做题目：
Heading 1 YES/NO/NG 2 Choose 3. 因为choose只有三道题。效率低，而且这三道题还不知在文章的什么地方。不如YES/NO/NG 六道题效率高。而且还能一边细读文章，一边做题目。对于最后三道题的选择还有帮助。我们按此顺序试下。
3 Heading 的分析
先对七个选项分析下
i) Seeking the transmission of radio signals from planets. 寻找来自行星的无线信号
ii) Appropriate responses to signals from other civilizations 对其它文明做适当响应
iii) Vast distances to Earth’s closese neighbours 到地球的最近的邻居的很远的距离
iv) Assumptions underlying the search for extra-terrestrial intelligence 支持寻找地球外生命的假定
v)Reasons for the search for extra-terrestrial intelligence 为什么要寻找地球外生命
vi) Knowledge of extra-terrestrial life forms. 外星生命形式的知识
vii)Likelihood of life on other planets. 其他星球有生命的可能性
第V项已被选做A段的主题。所以不用考虑。
但我们简单看下A段的头尾句，和主题匹配下。The primary reason for the search is basic curiosity. 首句做topic sentence. 直接给出寻找外星人的主要原因是好奇。末尾是另一个原因。首尾呼应 一致。无异议。
(B)看B段首尾句
In discussing whether we are alone, most SETI scientists adopt two ground rules(基本原则). First, UFOs are ignored.. Second, we make a very conservative assumption that the life form should like us. ….。尾句：解释这些生命应该在哪些方面像我们。首尾一致。所以
对应iv) Assumptions underlying the search for extra-terrestrial intelligence 支持寻找地球外生命的假定。
(C)看C段首尾句
Even when we make these assumptions, our underatanding of other life forms is still severely limited.看首句：似乎是vi) Knowledge of extra-terrestrial life forms. 外星生命形式的知识
再看尾句：That means that our nearest neighbours are perhaps 100 years away, which is almost next door in astronomical terms. 这似乎又符合iii) Vast distances to Earth’s closest neighbours
首尾不一致，而且都有相应的信息在所列heading中。这种情况下，得通读一遍这一段。
第三句开始，用了However做转折。我们说在句子中出现转折要警惕。意味着作者真正想表达的意思可能在这里。However引出的是作者认为外星生命存在是有可能的。那vii)Likelihood of life on other planets 是这部分的最好的概述。现在，哪个才应该是这段的heading呢?我们来看下，首先要否定的是iii) Vast distances toEarth’s closest neighbours。理由是：该句话是以肯定的方式给出，而在文章中，用了perhaps.也许。所以信息反映不完整。另外，该句话实际上是对外星生命存在的另一种表达。而且仔细分析最后一句：That means that our nearest neighbours are perhaps 100 light years away, which is almost next door in astronomical terms. 这意味着我们最近的邻居在100光年之外，这在太空概念上，几乎相当于隔壁邻居了。
文中传递的信息是100光年在太空角度看不远，还挺近。所以跟Heading里的Vast 的表达有些不一致。那么，vi)Knowledge of extra-terrestrial life forms与vii)Likelihood of life on other planets，哪个是这段的标题呢?文中先说我们对外星生命了解有限，但是，尽管这样，我们依然可以猜测，外星人存在是可能的。所以后面才是本段的重点。这个HEADING有些难度。所以C的答案是vii)Likelihood of life on other planets
(D) 首尾句一致，i) Seeking the transmission of radio signals from planets. 频率范围：1000到3000MHz.
(E) 首尾句一致。关于How we should react if we detect a signal from an alien civilisation. 所以
是ii) Appropriate responses to signals from other civilizations
4 Y/N/NG
21 Alien civilisations may be able to help the human race to overcome serious problems.
A 段： The mere existence of such acivilisation will tell us that long-term survival is possible, and gives us some cause for optimism. It is even possible that the older civilisation maypass on the benefits of their experience in dealing with threats to survival such as nuclear war and global pollution, and other threats that we haven’t yet discovered.
Answer: YES
22 SETI scientists are trying to find a life form that resembles human in many ways.
B段：Second, we make a very conservative assumption that we are looking for a life form that is prettywell like us. …but it will nevertheless resemble us in that it should communicate with its fellows, be interested in the Universe,…
所以ANSWER:YES
23 The Americans and Australians have co-operated on joint research project.
D段， 没有关于合作的信息。所以
Answer: NG
24 So far SETI scientists have picked up radio signals from several stars.
D段， Until now there have not been any detections from the few hundred stars which have been searched.
Answer: NO
25 The NASA project attracted criticism from some members of congress.
Answer: NG
26 If a signal from outer space is received, it will be important to respond promptly.
Answer: E段：Everybody agrees that we should not reply immediately.
Answer: NO
5 Choose
Choose no more than three words and/or a number. Choose, 意思是从文中挑，除了大小写外，其他不能修改。
18 What is the life expectancy of Earth?
A 段：the lifetime of a planet like ours is several billion years.
Answer: several billion years.
19 What kind of signals from other intelligent civilisations are SETI scientists searching for?
Answer:D 段 so all searches to date have concentrated on looking for radio waves in this frequency range.
Answer: radio waves
20 How many stars are the world’s most powerful radio telescopes searching?
D 段：searching the nearest 1000 likely stars
Answer: 1000
