英语学习内容所占比例在整个小学过程中越来越大，那么如何让英语锦上添花呢?总结英语知识点和复习资料就变得很有必要了。学大教育小编为大家准备了2016年三年级英语下册复习资料-句型专项归类希望能对大家有所帮助。
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. He will eat lunch at 12:00. I watched TV yesterday evening.
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.
He will not (won’t) eat lunch at 12:00. I did not (didn’t) watch TV yesterday evening.
注意 小结：否定句主要是在肯定句的基础上加上了否定词 “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”，你也可以把它们缩写在一起如“don’t , doesn’t , didn’t )。这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.
Are you going to buy a comic book tonight? Yes, I am. / 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. w W w .x K b 1.c o M
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.
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? 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……?
