选择题
The experts suggested the problem worth paying attention ____ at the meeting.
A．to be discussed
B．to been discussed
C．being discussed
D．should be discussed
答案
答案：A
本题考查非谓语动词。本题较为复杂。首先，这句话的主干结构为：The experts suggested the problem be discussed at the meeting. 不难看出suggest引导的宾语从句中要用“should do”，此处should省略了。其次“worth paying attention to”作定语修饰problem，因此A正确。
