【句型专项归类】

  1、肯定句:是指用肯定的语气来陈说的句子,如:I’m a student. She is a doctor. He works in a hospital.

  There are four fans in our classroom. He will eat lunch at 12:00. I watched TV yesterday evening.

  2、承认句:含有承认词或表示承认意义词的句子,如:I’m not a student. She is not (isn’t) a doctor.

  He does not (doesn’t) work in a hospital. There are not (aren’t) four fans in our classroom.

  He will not (won’t) eat lunch at 12:00. I did not (didn’t) watch TV yesterday evening.

  ☆注意☆

  小结:承认句主要是在肯定句的基础上加上了承认词 “not”。有动词be的句子则“not”加在be后面,可缩写成“isn’t,aren’t”,但am not 一般都分开写。没有动词be的句子则要先在主要动词的前面加上一个助动词(do,does,did),然后在它后面加上“not”,你也能够把它们缩写在 一起如“don’t , doesn’t , didn’t )。这三个助动词要依据人称和时态来选择,其中“does”只用于一般往常时主语是第三人称单数的状况,而“did”只用于一般过去时,不论主语是什么人 称和数,都用“did” 。

  3、一般疑问句:是指询问事实的句子,此类句子必需用“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.

  Are there four fans in our classroom? Yes, there are. / No, there aren’t.

  Are you going to buy a comic book tonight? Yes, I am. / No, No, I am not. (Yes, we are. / No, we aren’t.)

  Will he eat lunch at 12:00? Yes, I will. / No, I will not(won’t).

  Are they swimming? Yes, they are. / No, they aren’t.

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

  ☆注意☆

  小结: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。

  这三个助动词也要依据人称和时态来选择,其中“does”只用于一般往常时主语是第三人称单数的状况,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)和简单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? It’s a computer.

  What does he do? He’s a doctor.

  Where are you going? I’m going to Beijing.

  Who played football with you yesterday afternoon? Mike.

  Which season do you like best? Summer.

  When do you usually get up? I usually get up at 6:30.

  Whose skirt is this? It’s Amy’s.

  Why do you like spring best? Because I can plant trees.

  How are you? I’m fine. / I’m happy.

  How did you go to Xinjiang? I went to Xinjiang by train.

  其中how又能够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(几(数量)), how much(几(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? I have three pencils.

  How many girls can you see? I can see four girls.

  How many desks are there in your classroom? There are 51.

  ☆注意☆

  小结:

  how many 用来提问可数名词的数量,主要有以上三种句式搭配,

  How many + 名词复数 + do you have? 你有几……?

  How many + 名词复数 + can you see? 你能看见几……?

  How many + 名词复数 + are there…? 有几……?
