陈述句变否定句的方法：
1、句中有动词be( am , is , are ,was,were),情态动词（can / could , may , must ，will , would 等），助动词（如完成时态中的HAS / HAD ），变否定句时直接在这些词后加NOT 。
2、实义动词作谓语变否定句是加助动词don't , doesn't （主语第三人称单数）, didn't （一般过去时），原来的动词要还原。
3、祈使句的否定句是直接在句首加Don’t 。
如：Open the doo r,please .-> Don’t open the door ,please .)
4、不定式的否定句是在不定式前加not 。
如： She asks the boy not to play in the street.
