So he has not been to Beijing ,hasn't he?

『补：Let's和Let us的区别』

◇1.Let's是Let us的缩写。包括说话人和听话人双方在内，含有催促、建议或请对方一起行动的意思。在听话人表示赞同建议时可只用Let's.如：
---Shall we go by train？
---Yes，let's.

◇2.当请求对方允许自己（第一人称复数）做某事时，要用Let us，这里的 us 不包括听话对方在内，不能缩写为Let's.
如两个同学对老师说：
Please let us remove the bookshelf for you.
让我俩给你移动一下书架。

◇3.两者在构成附加疑问句时，方法不同。如：
Let's go to see the film,shall we ?
咱们去看电影，好吗？
Let us go to see the film,will you?
让我们去看电影，好吗？
