Question

--Are you going to buy a new camera?
--Yes. But there are so many cameras that I can't decide__
A. how to use                  B. where to sell       C. which to buy

Answer 1

C

試題分析：how to use如何用；where to sell哪去賣；which to buy買哪一個；句意：你打算買一部新的照相機嗎?——是的，但是這兒有如此多的照相機，以至于我不能決定買哪一個。結(jié)合語句可知選C。
點評：疑問詞加不定式作用相當(dāng)于一個賓語從句，其區(qū)分主要是依據(jù)疑問詞的不同來判斷。首先要理解每個選項的基本含義，然后結(jié)合語境具體分析。
