【答案】 stores；of；feel；is；the most comfortable；selling；songs；full；the best；really 【解析】【分析】本文介绍了作者小镇上的几家店铺。

（1）句意：那里有三家很棒的服装店。

根据Trendy Clothes可知store商店，基数词three后是名词复数，故填stores。

（2）句意：时尚服装店是最大的，它有最好的服务，总是让你在购物时有宾至如归的感觉。

of all，固定搭配，所有的，故填of。

（3）句意：时尚服装店是最大的，它有最好的服务，总是让你在购物时有宾至如归的感觉。

make sb+动词原形，是某人……，故此处是动词原形，故填feel。

（4）句意：好时光也很美好。

great是形容词，此处缺少系动词be，是，主语是Good Times第三人称单数，全文是一般现在时，故be用is，故填is。

（5）句意：它有最舒适的座位供你坐。

根据the newest clothes there. And可知and前后都是最高级，seats是名词其前是形容词，comfortable是形容词，最高级是most comfortable，其前有定冠词the，故填the most comfortable。

（6）句意：酷先生卖衣服的主意最多。

句子中用谓语has，故此处是非谓语动词，sell主语是主动故选，故用现在分词形式，故填selling。

（7）句意：有时他们会邀请一些著名的歌手来唱歌，表演有趣的节目。

sing song，固定搭配，唱歌，表示泛指用名词复数，故填songs。

（8）句意：所以店里总是挤满了人。

be full of，固定搭配，挤满了，故填full。

（9）句意：哪家商店最好？前文提到的三家服装店，故此处是最高级，good的最高级是best，最后的，其前有定冠词the，故填the best。

（10）句意：这很难回答，因为每个商店都有自己的特色菜。

副词修饰形容词difficult，real是形容词，really是副词，故填really。

Is there intelligent（有智力的）life on other planets? For years, scientists said "no." or "we don't know." But today this is changing. Seth Shostak and Alexandra Barnett are astronomers （天文学家）. They believe intelligent life exists（存在）somewhere in the universe. They also think we will soon contact them.
Why do Shostak and Barnett think intelligent life exists on other planets? The first reason is time. Scientists believe the universe is about 12 billion years old. "This is long enough for other planets to have intelligent life, "say Shostak and Barnett. The second reason is size the universe is huge. "Tools like the Hubble Telescope（哈勃望远镜）have shown that there are at least 100 billion galaxies, "says Shostak. "And our galaxy, the Milky Way, has at least 100 billion stars. Some planets going around these stars might be similar to the earth. "
In the past, it was hard to look for signs of intelligent life in the universe. But now, powerful telescopes（高倍望远镜）allow scientists to discover smaller planets-the size of Mars or the earth-in other solar systems, these planets might have intelligent life.
Have beings from space already visited the earth? "Probably not, "says Shostak. "It's a long way away. However, intelligent beings may contact us in other way, such as radio signals（信号）. In fact, they may be trying to communicate with us now, but we don't have the right tools to receive their messages. However, this is changing. By 2025, we could make contact with other life forms in our universe and we might help each other. "
（1）What is the main idea of Paragraph 2?
A. The age and size of the earth.
B. Something about the Milky Way.
C. The reasons why intelligent life might exist.
D. The earth is the only planet with intelligent life.
（2）Why was it hard to look for signs of intelligent life in the universe in the past?
A. There were not any smaller planets.
B. There were not any powerful telescopes.
C. The astronomers were not interested in them.
D. The Milky Way didn't exist at that time.
（3）Why haven't beings from space visited us yet according to Shostak?
A. Because they're afraid of us.
B. Because it's long way away.
C. Because they don't want to see us.
D. Because they don't know how to use radio signals.
（4）What does the underlined phrase "life forms" in the last paragraph mean?
A. Messages.
B. Tools.
C. Radio signals.
D. Intelligent beings.
【答案】（1）C
（2）B
（3）B
