小升初句子句式大全

知识精要

1． 陈述句句型的理解和综合运用

2. 肯定陈述句和否定陈述句的变形及应用

要点讲练

一、陈述句的概念

陈述句是陈述一个事实或者说话人的看法。它包括肯定句和否定句两种。陈述句在书写时句末用句号，而在朗读时则用降调。如：

I’m a student. I like dogs. I’m not a teacher.

二、陈述句的句子结构以及用法

陈述句可分为“肯定陈述句”和“否定陈述句”两种，简称为肯定句和否定句。

1、肯定句

在英语中，一般情况下，肯定句的基本结构为：主 谓 其他，例如：

主语一般包括人称代词或名词：I ,you, he ,she, dog, cat, some books等.

物主代词：this, that, 等。

谓语一般就是动词：be动词：is, are, am

助动词：do, does

行为动词：like, eat 等

Eg. Mr. Walker is an Englishman. 华克先生是英国人。　　 I am a tall boy. 我是一个高的男孩。

He does his homework. 他做他的作业。

2、否定句

否定句的基本形式包括以下两种：

（1）在系动词am, is, are, 助动词do, does, did，及情态动词will, would，can, could, may, might, shall, should, must等后面加上“not”。例如：

①句子中有be动词, 后直接加not，例如： 　　Eg. I am not (I’m not) a good swimmer. 我不是一个游泳的好手。　　 He is not (isn’t) a doctor. 　他不是一个医生

It is not (isnt) raining outside. 外面没有在下雨。

②情态动词will, would，can, could, may, might, shall, should, must后面加上“not”。例如： 　 Eg. 　 I wont do it again. 我不再做这种事。 　　 The old man cannot find his way home. 那个老人找不到回家的路。　　 I couldnt sleep last night. 昨夜我无法入睡。

③使用助动词“do”的否定句 　　 一般动词的否定句通常使用助动词“do”，句式如下：do（does, did） not V（原形动词）。

肯定句、否定句的互换：

非单三时用do, 单三时用does

主语非单三时肯定句：I like

主语非单三时否定句：I do not like English.

主语单三时肯定句：He likes English.

主语单三时否定句：He does not like English.

Eg. I dont know her very well. 我并不很了解她。　　 He doesnt like Chinese tea very much. 他并不很喜欢中国茶。　　 She didnt come to school this morning. 今天早上她没有来上学。 　　 Dont believe him. 不要相信他的话。

小口诀：

（2）使用“not”以外的否定词

①使用副词：never，seldom，hardly，little，neither等。

Eg. She never comes to school late. 她上学从不迟到。

She seldom comes to see me. 她不常来看我。

②使用形容词：no, few, little等。

Eg. I have no brothers. (=I don’t have brothers. ) 我没有兄弟。

He has few friends in Hong Kong. 他在香港几乎没有朋友。

③使用代词：nothing，nobody, none等。

Eg. I know nothing about computer. 对于电脑我一窍不通。

I found nobody in that house. 在那栋房子里我没看到任何人。

小贴士

特殊（肯定句与否定句互换词）：

1.some变为any

　　There are some birds in the tree.→There arent any birds in the tree.

　　但是，若在表示请邀请、请求的句子中，some可以不变。

　　Would you like some orange juice?

　　与此相关的一些不定代词如something, somebody等也要进行相应变化。

2.and变为or

　　I have a knife and a ruler.→I dont have a knife or a ruler.

3.a lot of (=lots of)变为many或much

　　They have a lot of friends.（可数名词）→They dont have many friends.

　　There is lots of orange in the bottle.（不可数名词）

　　→There isnt much orange in the bottle.

4.already变为yet

I have been there already. →I havent been there yet.
