?祈使句 用于表达命令、请求、劝告、警告、禁止等的句子

Watch your steps. ( 走路小心。—— 警告)
Look out! Danger! ( 小心! 危险! 强烈警告 ,已如感叹句) Keep off the grass.( 勿践草坪。 禁止)

1. Be型(即:Be + 表语(名词或形容词)+ 其它成分) Be careful! Don’t go too high. Be quiet, everyone! 2. Do型(即:动词原形(+宾语)+其它成分) Come in, please! Please open your books!

3.Let型(即:Let + 宾语 + 动词原形 + 其它成分)
