题目内容
It is not always easy for the public to see _______ use a new invention can be of to human life.
| A．whose | B．what | C．which | D．that |
B
解析试题分析：考查名词性从句。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。句意：群众是不容易看到的新的发明对人类有多大的用途。故B正确。
