这个 over 这个词。。以及 in that 表示原因的用法。

2、 状语的位置，习惯了把for+时间段的放在句子前后，偶尔看一下这样的表达会觉得不适应

3、 划线的用法。

4、 Astronomers no longer regard as fanciful the idea that they may one day pick up signal which

have been sent by intelligent beings on other worlds.

regard as fanciful the idea that….这个句子，刚开始看没太懂结构。

其实正常的应该是 regard the idea that they… as fanciful. 为了平衡句子结构所以把as fanciful这个给提前了。蛮地道的表达。。至少是蛮不中式英语的表达

在旧托福里，这样的语法结构也考过。

5、 Highly advanced civilizations may have existed on other planets long before intelligent forms

of life evolved on the earth.

Highly这个词。。。觉得很多赞美的感情都包括在里面了。。

最震撼的是看俺爸爸帮我改邮件， 最后一句 我本来写的是

I m waiting for your replay.。。。。。 蛮土的

Your reply will be highly appreciated.。。。以后俺发邮件最后一句都是这个了。。。

还有advanced，一个用法比较多的词，属于要掌握好的词吧。

6、 Aware of the fact that it would be impossible to wait thousands or millions of years to receive

an answer from a distant planet, scientists engaged in Project Ozma ate concentrating their attention on stars which are relatively close.

过渡句，连接2段间逻辑关系的句子。可以用做进一步详细的阐述，也可以做转折。 engage in 参与

7、 A single picture would tell us more than thousands of words.

这个简单句可以用于很多写作的论述中间。 比如说电脑的作用：

A simple operation on the computer would save us more than thousands of minutes.

8、 In an age when anything seems to be possible, it would be narrow-minded in the extreme to

ridicule these attempts to find out if there is life in other parts of the universe.

很好的结尾总结句子。还是那个 creativity v.s knowledge

In an age when anything seems to be full of innovation, it would be narrow-minded in the extreme to regard knowledge gained as superior than creativity.

今日总结：

1、其实好多词光背了发现自己写作用的词汇还是没有提高，而从课文中抽出句子来，一方面是对语感的提高，而且也了解了这个词的适用场合，或者说，在你想到一个表达的时候，反应出来的不是单词，而是一个句子
