题目

You can only be sure of___youhave at present;you cannotbe sure of something___you might get in the
future
A that;what Bwhat;/ C which;that D /;that
其他的为什么不对?翻译及考查知识点

答案

答案选B
解析：第一空填what,这是一个宾语从句,what you have at present 作为介词of 的宾语,构成介宾短语.第二空可以不填或者填that都可以,这是考察定语从句,从句缺少宾语,且先行词是something,因此可以填that或者不填.
