2. 有些过去分词作表语构成的谓语很接近被动语态。He found the room was packed / crowded with people.
Everything is settled now. You can leave for Beijing.
The town is surrounded on three sides by mountains. 这座城三面环山。
3. 如何区分被动语态和过去分词作表语？如果是被动语态，则其有相对应的主动语态。被动语态中的 -ed 分词可以是单词动词、介词动词、词组动词。被动语态中的-ed 不能被very修饰。
作表语的过去分词具有形容词的功能，可以被 very 等程度副词修饰，可以有比较级。不用介词 by引出施动者。
比较：
I am very interested in chess. (-ed分词作表语)
I was interested by what you told me. (被动语态)
下列例句中的过去分词都是做表语的。
He was dead drunk. 他烂醉如泥。
He is easily excited. 他很容易激动。
He felt cheated at the party. 他感到在宴会上受骗了。
In China agriculture is becoming more and more mechanized. 在中国农业正越来越机械化。
Conditions here are not what she's used to. 这里的条件不是她所能习惯的。

Water is composed of hydrogen and oxygen. 水是由氢和氧化合而成的。

It's nothing to get excited about. 这没有什么值得兴奋的。

I'm feeling tired out. 我感到累极了。
