英语就是这样( 100 ) It happened 为什么不能讲It was happened.

有人问为什么不能说：“It was happened.”。

英语的动词可分为两种他动词(TRANSITIVE VERB)和自动词(INTRANSITIVE VERB)。在英语的文法，一般上，自动词(INTRANSITIVE VERB)是不与be 动词（verb to be）配合的。Happen 是自动词(INTRANSITIVE VERB)，所以不能与be 动词（verb to be）的was在一起。

Come, go, swim, rain, occur, arrive 等等都是自动词(INTRANSITIVE VERB)，所以，如果把这些字配上了be 动词（verb to be）就是文法不对。 I was come, he was go, It was rained ,it was occurred 和 she was arrived都是错的。

但他动词(TRANSITIVE VERB)却可以与be 动词（verb to be）配而变了被动词（Passive Tense）.

I was caught. 我被抓了。

He was kicked. 他被踢。

They were questioned. 他们被问话。

如果不熟悉他动词(TRANSITIVE VERB)和自动词(INTRANSITIVE VERB)，你可要买一本好字典。字典中，它会给于提示每个动词是否他动词(TRANSITIVE VERB)和自动词(INTRANSITIVE VERB)。在字典里，（I）是代表自动词(INTRANSITIVE VERB)，（T）是代表他动词(TRANSITIVE VERB)。

还有，自动词(INTRANSITIVE VERB)不需要目标（Object）如下

He swims every day.

It rained.

但他动词(TRANSITIVE VERB)却需要目标（Object），如否这句子就不完整了。

I take. 不完整，需要目标（Object）

I take it. 完整的句子

She saw. 不完整，需要目标（Object）

She saw me. . 完整的句子
