【精析】C 句意：在詞典里查詢這些單詞的不同意見。詞語搭配。“look out” 意為“小心，當心;注意”;“look for”意為“尋找”; “look on” 意為“旁觀”。“look up”意為“查詢，查閱”。
4.Because they usually receive the same score on examinations ,there is disagreement asto is the better student.

5、---What do you think made Mary so upset?
--- __her new bike.
A. Lost B. As she lost C. Losing D. Because of losing
口語中會使用一些省略句，作題是若將被省略的成分補充完整，答案就會一目了然。此題將答句補全，就是her new bike made Mary so upset。顯然，只能選C，用動名詞作主語。
6、---Mr. Wang ,whom would you rather __ the important meeting?
A. have attend B. have attended C. having attend D. have to attend
有時將題干的句式轉換成自己更熟悉的句式，就很容易選出正確答案。如：將疑問句、強調句、感嘆句或倒裝句改為陳述句，將被動句改為主動句，將無序句調整為正常句。此題若將疑問句改為陳述句，就是I have Tom attend the important meeting。其中would rather后必須跟動詞原形，have sb do sth.所以選A。
