知识探究
Don’t arrive late for class. 不要上课迟到。
(1)本句是一个否定的祈使句,祈使句是以动词原形开头的,表示命令或
请求的句子。其否定句是在动词原形之前加 don’t。如:
Don’t do that again. 不要再做那样的事情了。
Don’t tell our teachers our secrets. 不要告诉我们老师我们的。
(2)肯定的祈使句:
① 句型:动词原形…...(省略主语)。例如:
Look at these holes ! 看这些洞。
② 有时,为了加强语气,可以在动词之前加 do。例如:
Do be quiet. 务必安静。
③ 用客气的语气表示祈使句时,可在句首或句尾加上 please,但如果在
句尾加 please,那么在 please 之前一定要加上一个逗号“,”。如:Keep 2
quiet, please. 请保持安静。
④ 祈使句中如果有唤语,一定要用逗号“,”将唤语与其他的内容隔开,
唤语置于句首或句尾。如:
Come here,Li Ming. 到这儿来,李明。
(3)祈使句与陈述句的改写:
① 祈使句=you must …..(陈述句)。如:
Be quiet. = You must be quiet. 安静。
② Please + 祈使句.= Will you please ……? 例如:
Please read after me. = Will you please read after me ? 请跟我读。
(4)祈使句“Let…..”句型
Let 作为动词常常用于祈使句,但表示意义并不相同。
① Let 表示“建议”,后面跟第一人称代词作宾语。如:
Let me try again. 让我再试一试。
② Let 表示“间接命令或愿望”,后面接第三人称代词作宾语。如:
Let him work out the problem by himself.
