Grammar其实句一般用来表示请求、命令、劝说、号召、警告等。在祈使句中， 通常省略第二人称主语you。肯定式以动词原形开头，否定式一般在动词原形前加dont。一、祈使句的肯定式1. 以行为动词原形开头，简称Do型。 e.g. Come here. 到这儿来。2. 以动词be开头，简称Be型。 e.g. Be quiet, please. 请安静。3. 以Let开头，简称Let型。 e.g. Lets go! 咱们走吧! 注意：有时可在祈使句的句首或句尾加上please，使语气显得客气、有礼貌。如果在句尾加please，应该用逗号与前句隔开。e.g. Go this way, please. 请这边走。二、祈使句的否定式1. Do型和Be型的否定式是在句首加dont。 e.g. Dont sit here. 不要坐在这儿。 Dont be late. 别迟到。2. 以let开头的祈使句，其否定式有两种： 一种是直接在句首加dont，另一种是 “let + 宾语 + not +动词原形+ (其他)”。 e.g. Dont let him go. 不要让他走。 Lets not go there. 咱们别去那儿。注意：“No+名词/动词ing形式”表示禁止或规劝，常用于公共场所。e.g. No photos! 禁止拍照！ No smoking！ 禁止吸烟！将下列句子翻译成英语。1. 请看这幅图画。2. 不要在教室里跑。3. 让我们帮助他。4. 在图书馆保持安静。5. 上课不要迟到。.
