become用法说明

1. 用作连系动词,其后可接名词、形容词、过去分词等作表语:

He became a teacher at (the age of) 17. 他17岁就当了老师。

The weather became warmer. 天气变得暖和起来。

注意:其后接过去分词时,可表示被动或结果;但表示被动时,其后一般不接 by短语。比如不说:

Soon the room became crowded bystudents.

他成为老师有十年了。

正:He became a teacher ten years ago.

正:It’s ten years since he became a teacher.

正:He has been a teacher for ten years.

误:He has become a teacher for ten years.

3. become 之后一般不接不定式表示“逐渐…” (此时可用 come / begin+不定式):

正:He began [came] to like English. 他开始喜欢英语起来。

误:He became to like English.

正:He became ill yesterday. 他昨天病了。

误:He became to be ill yesterday.

4. 用于习语 become of, 表示“发生”、“遭遇”等 (常与 what连用):

I don’t know what will become of me if I fail this time. 要是我这次不成功,我不知我会怎么样。
