●小升初英语必背知识点归纳六、句型专项归类：

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.

☆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.
