英语句式

在英语学习中应当注意句式的变化,它的变化是随所要表达的意思的变化而变化的.是想肯定还是要否定,是疑问还是反问,是时强调还是一般, 是命令还是陈述, 因此 ,不同的句式表达不同的语气.下面介绍几种句式:

一、 反意疑问句

反意疑问句是用来表示向对方提出反问的一种句式.表示说话人对所提问题的答案有所了解.有时不需要得到回答.

反意疑问句的结构分为两部分,即:陈述部分 和疑问部分 (疑问部分用简略形式),陈述部分与疑问部分用逗号隔开.

反意疑问句有两种形式,一种是前肯定后否定;另一种是前否定后肯定.如 :

You are a student , aren't you ? 你是个学生,对吗?

You are not a student, are you ? 你不是学生,对吗?

应当注意反意疑问句的答语, 与汉语略有区别,特别是前否定后肯定类型的反意疑问句. 例如: -----You are a student, are you ? 你是个学生,对吗?

----- Yes, I am . ( No, I am not ) 是的, 我是. (不是,我不是 . )

------- You are not a student, are you ? 你不是一个学生,对吗?

------- No, I am not .( Yes, I am ) 对,我不是. ( 不对, 我是 . )

当陈述部分是复合句时,疑问部分人称和谓语动词一般与主句一致,但是 当主句有I ( don't) believe ( think , suppose , guess ... )疑问部分人称和谓语动词应该与从句一致.主句的否定实际上是对从句的否定.例如: I don't think he will come , will he ? 我想他不会回来,对吧?

I think he can swim , can't he ? 我想他能游泳,对吧 ?

It was the boy who played on the street . ( 强调主语 )
