(一)句子种类两种分类法
1、按句子的用途可分四种:
1)陈述句(肯定、否定):He is six years old; She didn’t hear of you before.
2)疑问句(一般、特殊、选择、反意):Do they like skating? How old is he? Is he six or seven years old? Mary can swim, can’t she?
3)祈使句:Be careful, boys; Don’t talk in class
4)感叹句:How clever the boy is!
2、按句子的结构可分三种:
1)简单句:只有一个主语(或并列主语)和一个谓语(或并列谓语)。
e.g. He often reads English in the morning.

She likes drawing and often draws pictures for the wall newspapers.
2) 并列句:由并列连词(and, but, or等)或分号(;)把两个或两个以上的简单句连在一起构成。
e.g. You help him and he helps you.

3)复合句:含有一个或一个以上从句的句子。复合句包含:名词性从句(主语从句、宾语从句、表语从句和同位语从句)、定语从句和状语从句等。
e.g. The foreign visitors took a lot of pictures when they were at the Great Wall.

2、主语+不及物动词:e.g. We work.
3、主语+及物动词+宾语:e.g. Henry bought a dictionary.
4、主语+及物动词+双宾语(间接宾语+直接宾语):e.g. My father bought me a car.
5、主语+及物动词+复合宾语(宾语+宾补):e.g. Tom made the baby laugh.
