小学英语必背基础知识归纳

小学英语是很简单的，因为对语法的要求很低，这个阶段以听课为主，只要将课堂上的知识掌握好就足够了。下面是店铺为大家整理的小学英语必背基础知识，希望对大家有用!

小学英语知识归纳 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.

☆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. 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. 小学英语知识总结
