中学知识：become后跟动词什么形式

become是动词，后面一般不能跟动词原形，只能跟名词化的（动名词，也就是动词+ing），或者动词+ed或者动词分词作形容词用。

become的意思

vi.变为，成为；变得；变成；

vt. 适合，适宜；相称，相当；变成；发生

become的用法

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。

Soon the roombecame crowded.不一会儿房里就挤满了人。

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.

2.become是终止性动词，因此要表示“成为…有多长时间”，英语不能将become与表示一段时间的词或短语连用：

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)：

What has become of the girl?这个女孩后来怎样了?

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。
