  3,一般疑问句:是指询问事实的句子,此类句子必须用"yes",或"no"来回答.

  如:Are you a student ?Yes, I am No, I'm not.

  Is she a doctor? Yes, she is. No, she isn't.

  Does he work in a hospital ?Yes, he does. / No, he doesn't.

  Did you watch TV yesterday evening? Yes, I did. / No, I didn't.

  注意:

  一般疑问句是在肯定句的基础上,

  ①把动词be调到首位,其他照写,末尾标点符号变成问号即可.

  ②没有动词be的句子则要在句首加上一个助动词(do,does,did)再把紧跟在后面的动词变回原形,末尾标点符号变成问号即可.

  这三个助动词也要根据人称和时态来选择,其中"does"只用于一般现在时主语是第三人称单数的情况,而"did"只用于一般过去时,不论主语是什么人称和数,都用"did" .一般疑问句有个重要的原则就是问和答要一致,即问句里的第一个单词(助动词)和简略答句里的这个词是一致的.

  4,特殊疑问句:以特殊疑问词(what , where , who , which , when , whose , why , how等)开头引导的句子.此类句子应该问什么就答什么,不能用"yes ,no"来回答.如:

  What is this?

  Where are you going?

  Who played football with you yesterday afternoon?

  When do you usually get up?

  Why do you like spring best ?

  How are you?

  注意:

  其中how又可以和其他一些形容词连用组成特殊疑问词组用来提问,如: how many(多少(数量)), how much(多少(钱)), how tall(多高), how long(多长), how big(多大), how heavy(多重)

  例句:How many pencils do you have ?

  How many girls can you see ?

  how many 用来提问可数名词的数量,主要有以上三种搭配,

  How many + 名词复数 + do you have 你有多少……

  How many + 名词复数 + can you see 你能看见多少……

  How many + 名词复数 + are there… 有多少……

  七 完全缩略形式

  1、简缩形式的变法:把倒数第二个字母,通常是元音字母变成' 但are除外,are要把a打成' 。Eg:he is=he's they are=they're

  2、简缩形式和完全形式的汉语意思相同。

  3、把完全形式变成简缩形式时,一定要注意第一个字母的大小变化。Eg:What is =What's

  4、记住一个特殊变化;let's =let us 让我们(不要把' 变成i) 5、记住:thisis 没有简缩形式this's(错误)

  5.常见的缩略形式:

  I'm=I am he's=he is she's=she is they're=they

  are you're=you are there's=there is they're=they are

  can't=can not don't=do not doesn't=does not

  isn't=is not aren't=are not let's=let us

  won't=will not I'll=I will wasn't=was not
