SectionAPart2SectionA(GrammarFocus－3c)Unit4Don'teatinclass.英语祈使句(一)祈使句的定义

祈使句一般用来表示请求、命令、建议、警告等。祈使句的对象(主语)是第二人称you，通常被省略。句末用感叹号或句号，朗读时常用降调。在表达请求或劝告时，可在祈使句前或句末加上please，使句子的语气更加委婉或客气。祈使句一般没有时态的变化，也不能与情态动词连用。语法导学(二)祈使句的形式◆肯定祈使句(1)Do型——动词原形(＋宾语)＋其他成分如：Openthedoor，please.请打开门。(2)Be型——Be＋表语(名词或形容词)＋其他成分如：Becarefulwhenyoucomeacrossthestreet.过马路时要小心。(3)Let型——Let＋宾语＋动词原形＋其他成分如：Let'sgotraveling.咱们去旅游吧。语法导学◆否定祈使句(1)Do型和Be型的否定式，在句首加Don't或Never。如：Don'tbelateagain.不要再迟到了。Neverforgetme！别忘了我！(2)Let型的否定式分两种：①let开头的祈使句，如果后面接第一、第三人称名词或代词的宾格，可在let前加don't，也可在let后宾格的名词或代词后面加not。语法导学如：Don'tletmegowithhimtomorrow.＝Letmenotgowithhimtomorrow.明天不要让我和他一起去。②如果是以let's开头的祈使句，必须在let's后面加not。如：Let'snotgoswimmingthere.我们别去那里游泳吧。(3)No＋名词或动词－ing形式，表示禁止做某事。如：Nophotos！禁止拍照！Notalking！禁止说话！语法导学————基础夯实————一、单项选择。(
