1. Instead of waiting for the teacher to explain， they try to find the patterns and rules for themselves.

　　動詞不定式to explain和名詞 teacher構(gòu)成復合結(jié)構(gòu)，作wait for的賓語，稱為復合賓語。此類用法在英語中很常見，例如：

　　1) I''ll get someone to repair the bike for you.(我去找人來幫你修自行車。)

　　2) He wants you to call him in the afternoon.(他要你下午給他打電話。)

　　3) The teacher is waiting for the students to answer the questions.(老師在等學生們回答問題。)

　　4) You can count on him to give you full support.(你放心，他會給你全力支持。)

　　請注意 instead of 與 instead 的區(qū)別：

　　1) Instead of staying at home watching TV， he went out for a walk.

　　He didn''t stay at home watching TV， instead he went out for a walk.

　　2) Instead of having milk for breakfast， he had a cup of coffee.

　　He didn''t have milk for breakfast， instead he had a cup of coffee.

　　2. When they guess wrong， they guess again.

　　wrong常常作形容詞或動詞用，而本句中的wrong則作副詞用。請注意下面句子中wrong的詞類：

　　1) He was annoyed that he had been given some wrong information.(wrong adj.錯誤的)

　　2) I knew I had wronged her terribly when I gave her all the complaints.(wrong v. 冤枉)

　　3) The whole class burst into laughter when the teacher pronounced her name wrong.(wrong adv.錯，不對)
