5.要点点拨

（1）I will never try to catch a falling dinosaur.

我永远也不会设法接住一个正在下落的恐龙。

falling 是fall 的-ing 形式，在句中作dinosaur 的定语。不及物动动词的 -ing 形式可表示正在进行或尚未结束的动作，而过去分词可以表示完成了的动作。例如：

We live in a changing world. 我们生活在一个变化的世界。

You’d better drink much boiled water when you catch cold.

得感冒后你最好多喝开水。

Our country is a developing country, but the US is a developed country.

我国是个发展中国家，而美国则是发达国家。

（2）You advised him to use a ladder, but he didn’t listen.

你建议他用梯子，但是他没有听你的。

advise sb. to do sth. 意为“建议某人做某事”；

advise sb. not to do sth. = advise sb. against sth. /doing sth.

意为“劝告某人不要做某事”。例如：

Police are advising people to stay at home. 警方告诫民众要留在家里。

I'd advise you not to tell him. 我劝你别告诉他。

My mother strongly advised me against going out on my own.

妈妈极力奉劝我不要单独外出。

（3）“Don't climb too high,” she warned. “别爬得太高，”她提醒我说。

本句中 high 用作副词，指具体的“高”。例如：

I held the flag high. 我把旗子高高举起。

常用 high 的短语有：aim high ( 力争上游 )，hold one's head high ( 昂首 )，search high and low ( 到处搜寻)， run high (浪大， 激动)， fly high (有雄心)等。副词highly 通常指抽象的“高，高度”。例如：

He spoke highly of me. 他高度赞扬了我。

highly 也用于修饰形容词，意思是“很，极，高价地”。例如：

She is highly pleased. 她很高兴。

The story is highly interesting. 这个故事极有趣。

The worker is highly skilled. 那工人技术高超。

The engineer is highly paid. 那位工程师收入很高。

（4）She watched me climb higher and higher. 她看着我爬得越来越高。

1)比较级 +and+ 比较级，表示“越来越……”。例如：

more and more( 越来越多 )，better and better( 越来越好 )

She runs faster and faster. 她跑得越来越快。

2) watch, see, notice, hear 等感官动词的宾语跟省略 to 的动词不定式作宾补。例如：

I often hear him sing this English song. 我经常听见他唱这首英文歌曲。

Did you notice her go out? 你注意到她出去了吗？

设计意图：让学生能抓住文中重点词汇和句型，熟读记忆。
