句型轉換肯定變否定.doc

句型轉換講解及練習一、變否定句的方法1. 如果句子中有be動詞（is， am， are）或者情態(tài)動詞（can），就在這些動詞后面加上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. 如果句子中沒有be動詞或者情態(tài)動詞，就在句子中的動詞前面加上助動詞dont或者doesnt，(動詞用原形加dont,動詞不變；動詞用三單加doesnt,動詞恢復原形)需要注意的是在加上助動詞doesnt后，句子中的動詞應變成原形例如： I have a cat. I_ _ a cat. He goes to work at 6:00. He _ _ to work at 6:00.3.祈使句變否定句的方法最簡單：在句子最前面加上Dont, 它后面變?yōu)樾懢涂梢粤?。例如：Look at me.- _ _ at me.注：變否定句時，如果句中有some，要變?yōu)閍ny,and要變?yōu)閛r.練習一：將下列句子改為否定句1.There is a computer on the desk. _2.
