否定句含有实义动词的陈述句，要变为否定句，需要借助don't/doesn't.当主语是第三人称单数时，要借助doesn't,其余人称要借助don't.变否定方法：1.先看主语的人称，来决定选用doesn't还是don't2.如果主语是第三人称单数，在谓语动词前加doesn't;如果主语是第三人称以外的人称，要在谓语动词前加don't.例句：1.I go to school every day.（变否定句）I don't go to school every day.2.She likes red coat.（变否定句）She doesn't like red coat.3.He often watches TV on Sunday.（变否定句）He doesn't often watch TV on Sunday.4.It looks like a hat.（变否定句）It doesn't look like a hat.5.They play basketball on the playground.（变否定句）They don't play basketball on the playground.
