As is well known, ____ is important to learn grammar when learning a foreign language, but ____ is the most important is to remember enough words.
A. it, it B. what, what
C. it, what D. what, it
本题很容易错选 A,认为两空均考查形式主语。其实本题的答案是 C,第一空填形式主语,真正的主语是其后的不定式 to learn grammar。第二空填 what,what is the most important 是主语从句,注意 what is the most important 后的谓语动词 is。请做以下类似试题:
(1) I know ______ is important to know my own limitations, but _______ is difficult is to help others to know their own limitations.
A. it, it B. what, what
C. it, what D. what, it
(2) Yes, ______ is difficult to find a job nowadays, but _____ is more difficult is try to find such a job with a high salary but little things to do.
A. it, it B. what, what
C. it, what D. what, it
答案均为:C
