2、令句。祈使句因对象（即主语）是第二人称，般现在时，句末则使用句号或感叹号来表示结束，（去洗你的手。命令） （请安静。请求） （对姊妹要和善。劝告）（走路小心。警告） （小心！危险！强烈警告） （勿践草坪。禁止）（禁止停车。禁止）（禁止吃喝。禁止 ） （禁止乱扔垃圾。禁止 ）祈使句也常把主语“ You ”表达出来，使对方听起来觉得柔和些，例如： You go and tell him, Chris. （克立斯去告诉他。 ）1.2 概念口诀 祈使句无主语，主语 you 常省去； 动词原形谓语当，句首加 dont 变否定； 朗读应当用降调，句末常标感叹号。1.3 表现形式1.3.1 肯定句1 Do
