Question

It is not always easy for the public to see _______ use a new invention can be of to human life.

A．whose

B．which

C．that

D．what

Answer 1

D

试题分析：句意：群众是不容易看到的新的发明对人类有多大的用途。这里see后面接的是一个宾语从句，该从句缺少定语，变为陈述语序为：A new invention can be of what use to human life. 本题易误选为C项，which表示“在某个范围内的选择”，意为：哪个，哪些。本句并未涉及范围，故答案为D项。
点评：本题难度适中。
即学即练: I do every single bit of housework__________my husband Bob just does the dishes now and then.
A. since      B. while     C. when        D. as
解析：B。句意：考查并列转折连词while的用法。这里表示“我”和丈夫做家务的对比。根据句意，选B。
