句型转换肯定变否定.doc

句型转换讲解及练习一、变否定句的方法1. 如果句子中有be动词（is， am， are）或者情态动词（can），就在这些动词后面加上not。例如： I am a student. I _a student. He can see a cat in the picture. He _see a cat in the picture.2. 如果句子中没有be动词或者情态动词，就在句子中的动词前面加上助动词dont或者doesnt，(动词用原形加dont,动词不变；动词用三单加doesnt,动词恢复原形)需要注意的是在加上助动词doesnt后，句子中的动词应变成原形例如： I have a cat. I_ _ a cat. He goes to work at 6:00. He _ _ to work at 6:00.3.祈使句变否定句的方法最简单：在句子最前面加上Dont, 它后面变为小写就可以了。例如：Look at me.- _ _ at me.注：变否定句时，如果句中有some，要变为any,and要变为or.练习一：将下列句子改为否定句1.There is a computer on the desk. _2.
