B 语法聚焦1: “Let's + 动词原形” 引导的肯定祈使句“Let's + 动词原形 + 其他成分” 构成肯定祈使句,意思是“让我们······吧”,这个结构用于提议和对方一起做某事。
小贴士
Let's是Let us的缩写,两者都能引导祈使句,但是意思稍有差别。
Let us ... 一般表示恳求得到对方的准许,意思是“你让我们······吧”。
Let's ...则表示期待对方接受提议、一起行动,意思是“我们一起······吧”。试分析以下场景:
Father: Don't eat too many potato chips.
Child A: Let us eat just a little, please.
Child B to A: Let's eat while watching a movie.
