疑问句

　　疑问句分为一般疑问句、特殊疑问句、选择疑问句和反意疑问句。

　　1.一般疑问句

　　一般疑问句通常以助动词开始，要求以yes 或no回答。如：

　　“Will you pass on a message to him?” “Yes， what's it?”

　　“Do you like sports?” “No， I prefer reading in my spare time. ”

　　2.特殊疑问句

　　特殊疑问句以疑问代词开头，后面通常接一般疑问句，如果疑问词或其修饰的词作句子的主语，后面应用陈述句句序。如：

　　How much did she charge ?

　　Who is responsible for the accident?(be responsible for 为……负责)

　　“______ do you record the temperature in the lab?”

　　“Every two hours.”

　　A. How soon B. How long C. How often D. How much(答案 C how often 表示频率，how soon最快……，how long 一段延续的时间，how much 问价钱)

　　3.选择疑问句

　　选择疑问句在结构上类似于一般疑问句，选择的两部分由or连接起来。如：

　　Do you prefer coffee or tea? -Either will do.

　　Are you from Shanghai or Suzhou?-I'm from Suzhou.

　　4.反意疑问句

　　反意疑问句由两部分组成，前一部分用陈述句的形式，后一部分是一个简短的问句。如果前一部分用肯定形式，后一部分通常用否定形式，前一部分用否定形式，后一部分就用肯定形式，两部分主语的人称、时态应保持一致。如：

　　You are going out today， aren't you?

　　We can't take the books out， can we?

　　当反意疑问句的前一部分是否定句，或含有no， nothing， never， hardly， seldom等词时，回答时应特别注意。事实上肯定的用yes，事实上否定的用no.

　　You won't be away for long， will you?-No， I'll be back in ten minutes.

　　He is hardly ten， is he?-Yes， he is ten.

　　You haven't any objection to the idea， have you?-No， I haven't.(objection to 反对，to是介词)

　　They have no classes tomorrow， have they?-No， they haven't.

　　日常用语中有些反意疑问句构成与上述不同，有其独特的方式。如：

　　Have a cup of tea， will you?

　　Let's meet at the station， shall we?

　　What a lovely day， isn't it?
