You must tell him the news as soon as you____him.

A.see.
as soon as 这里跟if, when那些用法差不多

Answer 3

看你想表达什么了。基本时态是过去时。如果想表达 去年年底 已经完成某事，就用过去完成时，想表达去年年底正进行某事，就用过去正在进行时，以此类推。

追答

下面的题怎么做? 选A，刚才好像没看到有题目，不好意思哈。
You must tell him the news as soon as you____him.
A.see. B.sees. C.will see. D.is seeing

下面的题，选D

根据的你问题，说明你的时态没掌握好，两个解决办法，一是尽快找看关于时态的语法点，边做题边总结自己的心得。第二是根据语义分析，by```是表示到···为止，从中文就可以判断，一般说到···为止，后面就会说···已经怎么怎么样了。时态中，have done 就是表示已经、完成的意思了。然后根据所给时间，在 将来完成、现在完成和过去完成中进行选择。
