(五)一般疑问句及特殊疑问句

　　句子基本是：简单陈述句，由简单陈述句转变成肯定句，否定句，疑问句。疑问句是用来提出问题。英语中有四种疑问句: 一般疑问句、特殊疑问句、选择疑问句和反意疑问句。我们现在已经接触到了前两种疑问句。后两种疑问句以后我们还会学到.

　　一.一般疑问句：

　　英语中要用 yes和no 来回答的疑问句叫一般疑问句。如:

　　2)Is it a car ?　Yes, it is .\No, it isn't . -- be动词引导

　　3)Is this your ruler ?　Yes, it is .\No, it isn't . -- be动词引导

　　4)Do you like bananas ? -- 含实义动词

　　Yes, I like bananas. \ No, I don't like bananas.

　　5)Can Ming hear a drill ? --含情态动词

　　Yes , Ming can hear a drill.\No,Ming can't hear a drill.

　　三 特殊疑问句(又叫wh-question)

　　用特殊疑问词来提出问题的疑问句叫作特殊疑问句。特殊疑问词一般要放在句首。常用的疑问词有what who ，which how 等这些词都以wh 开头(包括how)所以也叫作wh-question。特殊疑问句要求回答具体内容。不能用yes或no回答。结构：疑问词+一般疑问句。回答不能用yes / no(或相当于yes / no)回答的问句。答句的句式同肯定句句式：如：

　　What can you see ?　I can see a cat.

　　What can you hear ?　I can hear a bus.

　　What can you do ?　I can sing and dance.

　　What is it ?　 It's a panda.

　　What do you like ?　I like playing football
