1）用“Let’s” 开头的祈使句后面接动词原形，建议对方和自己一起做某事，句尾常常加 “shall we？”，“OK” 等用于征求对方看法的词语，从而使语气缓和得多。例如：Let’s cross over here while the light’s green.
Let’s call it a day now， OK？
Let’s go upstairs， shall we？
“Let’s. 。 。 ， shall we？” 句型可以和 “Shall we…？” 换用，肯定回答常用 “Yes，let’s…” 。例如：—Shall we listen to some music？ —Yes， let’s listen to some.

I suggest （that） we （should） take the night train.
“劝告”偏重于为对方着想，替对方出主意、想办法，或者是长辈对晚辈、师长对学生、有经验的对无经验的人讲应该做什么或怎样去做。
表达“劝告”的常用方法有：
1） “You’d better…”句型表达随便的劝告，口语中有时省略had和主语you。例如：You’d better take an umbrella. It’s going to rain.
Better do it yourself. It’s no good depending on others.
2） 用should， ought to， might， could 等情态动词表达责任和义务。例如：—Please tell me which courses to take in the first term.

3） 用advise， advice 等词汇。例如：I strongly advise you to see the doctor.
