小学英语句型大全

1、肯定句是指用肯定的语气来陈述的句子。如:


I’m a student.


She is a doctor.


He works in a hospital.


There are four fans in our classroom..


2、否定句含有否定词或表示否定意义词的句子。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.


☆小结:


1)否定句主要是在肯定句的基础上加上了否定词 “not”。


2)有动词be的句子则“not”加在be后面,可缩写成“isntarent”,但am not 一般都分开写。


3)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(dodoesdid),然后在它后面加上“not”,你也可以把它们缩写在一起如“dont , doesnt , didnt )。


4)上面三个助动词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” 。


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.


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


☆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(dodoesdid)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? It’s a computer.


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


What does he do? He’s a doctor.


Which season do you like best? Summer.


Who played football with you yesterday afternoon? Mike.


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


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

 

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

 

☆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() 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.

 

☆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……?
