573 祈使句的反意疑问句有几种类型
1 肯定祈使句的反意疑问句,后面一般用will you ,但也可以用can you或could you,表示更委婉的语气,或者用won't you,表示邀请。
Go and get some water, will you ? 去弄点水来,好吗?
Please wait for me here, can/could you ? 请在这里等我,好吗?
Have another cup of tea, won't you ? 再喝杯茶,好吗?
2 否定祈使句的反意疑问句,后面只用will you 。
Don't close the window, will you ? 不要关上窗户,好吗?
Don't tell her the news, will you ? 不要把消息告诉她,好吗?
3 以let's 开头的祈使句,变为反意疑问句时,后面要用shall we ,因为let's 表示“提出建议”,包括对方在内,意为“让我们……”。
Let's go shopping, shall we ? 我们去买东西,好吗?
Let's go to school, shall we ? (正)咱们上学去,好吗 ?
Let's go to school, will you ? (误)
Let's go to school, don't we ? (误)
4 以let me和let us 开首的祈使句,变为反意疑问句时,后面要用will you ,因为let me相当于you let me, let us相当于you let us,省略的主语都应是you。
Let me do the work, will you ? 让我做这项工作,好吗?
Let us stay in the room, will you ? 让我们待在这个房间里,好吗?
比较
Let's/Let us have a rest, shall we ? 我们休息一下好吗?(提出建议,包括对方在内)
Let us have a rest,will you ? (你)让我们休息一下,好吗?(不包括对方在内,故本句的Let us不可改为Let's)
