初中英语祈使句讲解及练习

1、初中英语一一祈使句祈使句指的是表示命令、请求、建议或劝告的句子。其主语you常省略，谓语动词用原形，句末用感慨号或句号，读降调。1. 肯定的祈使句1动词原形+其他Stand up, please. = Please sta nd up.请起立。2Be + n./adj.Be a good boy!要做一个好孩子！Be careful! = Look out! = Take care!小心 / 留神!3Let +宾语+动词原形+其它成分Let me help you.让我来帮你。Let' s go to school together.咱们一起上学去吧。2. 否认的祈使句(1) Don&
