(单选题)
______ they have in mind may be precisely that there are too many about general questions.
A.That
B.When
C.Where
D.What
参考答案:D
参考解析:
考查what引导的主语从句。句意:他们的想法可能恰恰是,一般性问题太多了。分析句子成分可知,______ they have in mind为主语从句,may be为主句谓语动词,that there are too many about general questions充当be动词后面的表语从句,在主语从句中明显缺少have后面的宾语,应该填入连接代词。故选D。
