Question

The old woman insisted that the book Mr.Thompson talked about ( A ).
A.was worth reading B.being worth reading
正确答案是A我知道,请问B为什么错呢,请高手指教,

Answer 1

the book Mr. Thompson talked about 中,Mr. Thompson talked about 作定语从句,mr thompson 谈论的这本书,the book是从句部分的主语,was worth reading是谓语, being worth reading是非谓语动词,所以不能作谓语.
