【正确答案】 A

【答案解析】[解析]
Most people think of astronomers as people who spend their time in cold observatories peering through telescopes every night. In fact, a typical astronomer spends most of his/ her time analyzing data and may only be at the telescope a few weeks of the year. Some astronomers work on purely theoretical problems and never use a telescope at all. You might not know how rarely images are viewed directly through telescopes. The most common way to observe the skies is to photograph them.

[分析] 观点意见的判断。
根据题干要求注意文中大多数人的观点，发现原文的第一句提供了相关信息“Most people think of astronomers as people who spend their time in cold observatories peering through telescopes every night．”即“大多数人认为天文学家每天在冰冷的天文台用望远镜观测夜空”，由此可判断选项A的说法与原文相符，是正确答案。
[解题关键] 掌握文中哪些是一些人的观点，哪些是文章的观点对解题很重要。听者可通过信号词或常用表达法来帮助判断。如文中使用most people think of...的方式表示一些人的观点，而用in fact形式来表述作者认为正确的观点。

【正确答案】 C

【答案解析】[解析]
Lufthansa said Tuesday that traffic in the first seven months of this year rose 16.8 percent, helped by increased demand on Asia-Pacific routes, as well as gains in Europe and on African and Middle East routes. The German carrier swung to a first-half net profit of 39 million euros from a loss of 392 million in the first half of 2003. This too was below an average analyst forecast of 105 million euros.

[分析] 数字信息的找寻和判断。
根据题干中关键词first-half net profit在原文中找寻相关信息，发现“The German carrier swung to a first-halfnet profit of 39 million euros...”，将数字与各选项对照可知，只有选项C与原文相符，是正确答案。
[解题关键] 通过题干关键词的引导，排除干扰项。原文中关于数字的信息颇多，更需要听者抓住这一技巧。

【正确答案】 B

【答案解析】[解析]
The most spectacular thing about the sea cucumber is the way it defends itself. Its major enemies are fish and crabs, when attacked, it squirts all its internal organs into the water. It also casts off attached structures such as tentacles. The sea cucumber will eviscerate and regenerate itself if it is attacked or even touched; it will do the same if the surrounding water temperature is too high or if the water becomes too polluted.

[分析] 事实细节的找寻和判断。
根据题干要求可在文中发现以下内容“The sea cucumber will eviscerate and regenerate itself if it is attacked or even touched；it will do the same if the surrounding water temperature is too high or if the water becomes too polluted．”即“若海参遭到攻击或碰触，它就会将自己的内脏抛出，再生出一副来；若海水温度过高或水质污染严重，海参也会这样做”，显然只有B的说法与原文不符，因此该项是正确答案。
[解题关键] 掌握同义词替换，有助于迅速定位原文相关信息。如原文中单词eviscerate与题干中单词release意思在此文中相同，都有“取出内脏”的含义。

【正确答案】 C

【答案解析】[解析]
One of the worst typhoons to hit China in several years has killed 63 people and injured more than 1,800 as it battered southeastern Zhejiang Province. Most of the casualties occurred when homes collapsed. Officials had evacuated 400,000 people to escape the typhoon that was forecast to be the worst since 1997 when a storm ripped into China, killing nearly 250 people and causing 19.8 billion yuan in economic losses.

[分析] 数字信息的找寻和判断。
根据原文“Officials has evacuated 400,000 people to escape the typhoon that was forecast to be the worst...”可知政府在作出台风预报后就疏散了人们，而不是如选项D所言疏散是为了避免更大的灾害，暗示疏散是台风发作之后才进行的；根据原文关于1997年台风的描述“…killing nearly 250 people and causing 19.8 billion yuan in economic losses．”可知选项A中数字前more than与原文nearly不符，而19.8与选项B中90.8不符；根据原文“injured more than 1,800 as it battered southeastern zhejiang Province”，选项C内容与之相符，因此该项是正确答案。
[解题关键] 掌握与数字及其相关的信息，可帮助正确判断选项。本题较为复杂，既考查听者听数字的能力，又考查听者对数字相关信息，如原文数字前的nearly等注意情况。

【正确答案】 D

【答案解析】[解析]
Seventeenth-century houses in colonial North America were simple structures that were primarily functional, carrying over traditional designs that went back to the Middle Ages. During the first half of the eighteenth century, however, houses began to show a new elegance. As wealth increased, more and more colonists built fine houses.

[分析] 因果关系的判断。
根据原文有关18世纪北美殖民地建筑风格改变的描述是“As wealth in-creased，more and more colonists built fine houses．”由此可见财富的增长是其原因。因此，选项D的说法是正确的。
[解题关键] 掌握表因果关系的信号词，有助于迅速在原文定位信息点，并作出正确的因果关系判断，该文中使用了信号词as。
