Question

--- What do you think of Harry, our new roommate?
--- I am not sure, but he is always asking ______ questions and      them are very hard to answer.

1. A.
   a great many of; a great number of
2. B.
   a great many; many of
3. C.
   a great number; a great many of
4. D.
   a large amount of , many

Answer 1

B
考查短語(yǔ)“許多的，大量的”表達(dá)。a great many + 可數(shù)名詞的復(fù)數(shù)，不用再加of，a great number of +可數(shù)名詞的復(fù)數(shù)，a large amount of+ 不可數(shù)名詞，句意：你認(rèn)為哈利怎么樣，我們的新同事。我不能確信，但是他總是問(wèn)許多問(wèn)題，他們的許多很難回答。所以選B。
