二、常识语境法

常识语境法指的是，同学们在补充省略成分时要充分考虑句子本身的语境，有时还要结合一定的生活常识和学科常识，即补充完整的句子不仅要符合语法，而且要符合情理。如：

1. “I like you more than her, my dear.” “You mean more than ____love her or more than she loves ____?”

A. you, me         B. she, you          C. I, me         D. I, you

分析：做对此题的关键是要弄清填空句是个省略句，补充完整为 You mean that you love me more than you love her or that you love me more than she loves me? 句意为“你是说你爱我胜过你爱她，还是说你爱我胜过她爱我？”，所以答案应选A。若选其他答案，从语法上也是对的，但不合情理。

2. Boris has brains. In fact, I doubt whether anyone in the class has _____IQ.

A. a high          B. a higher         C. the higher         D. the highest

分析：此题答案为B此句实为Boris has brains.In fact,I doubt whether anyone in the class has a higher IQ than him之省略。省略than him后不仅句意仍然清楚，而且显得更为简洁。句意为“……我怀疑班上有没有哪个人比他智商更高”，即“我认为他可能是班上智商最高的”。请再看以下类似的题目(分析理由同上，答案均选A)：

(1) How beautifully she sings! I have never heard _____ voice.

A. a better         B. a best      C. the better      D. the best

(2) “I’ve never found _______ job.” “Congratulations.”

A. a better         B. a best       C. the better      D. the best

(3) “What do you think of the service here?” “Oh, wonderful. We couldn’t have

found _______ place.”

A. a better         B. a best       C. the better      D. the best

(4) How cold it is! We’ve never had ______ day this winter.

A. a colder   B. a cold       C. the coldest     D. the colder
