选择题
You can only be sure of _____ you have at present; you cannot be sure of something _____ you might get in the future.
A．that; what
B．what; 不填
C．which; that
D．what; which
答案
答案：B
题目分析：考查关系词。句意：你只能确定你现在拥有的东西，你不能确定你将来可能会得到什么东西。第一个空既作介词of的宾语又做have的宾语所以用what做兼词，引导宾语从句。第二个句子是定语从句，先行词是something，在定语从句中做get的宾语，关系词用that或省掉不填，不能用which。所以答案选B。
