宾语从句的时态受主句的限制， 既：主句是一般现在时态，从句根据实际情况 而定。 主句是一般过去时态，从句用相应的过去的时态。如果从句的动作发生在主句 之前，则从句要用过去完成时态。 ? 例: ? 1)She says that she is a student. ? She said that she was a student. ? 2)She says that she will fly to Japan in a week. ? She said that she would fly to Japan in a week. ? 3)She says that she has finished her homework already. ? She said that she had finished her homework already. ? 4)She says that she can sing a song in English. ? She said that she could sing a song in English. 如果宾语从句说的是客观真理、自然现象或事实时，这时宾语从句要用一般现 在时态 ? 例：The teacher said that the earth goes round the sun.
A. 由that 引导的陈述句性的宾语从句，在很多动词如say, think, wish , hope, see, believe, agree, expect, hear , feel等动词后。连词that只起连接作用 ，在从句中不做句子的成分，也无词汇意义，在口语中常被省略，但在大多 数情况下还是以不省为好，特别是在笔试中。 例：I told him that he was wrong. B. 由 连词if、 whether 引导的表示“是否…”的宾语从句。Whether,if 在从句 中不做句子的成分，一般情况下，whether和if 可以替换。 例：I don’t know if/whether he will come tomorrow. The teacher asked if/whether we had finished the experiment. C. 由wh-引导的宾语从句。 连接代词who, whom,whose, what, which, 连接副词when, where, why, how 等连接的宾语从句，它们在句中即有连接 从句的作用，又在句中充当句子的成分。 例：Do you know which film they are talking about? (which做定语)
? 在许多带有复合宾语的句子中，that引导的宾语从句经常 移到句子的后面，而用it做形式宾语。 ? 例：We think it wrong that he told a lie to everyone (我认为他向每一个人撒谎是错误的)
? 在介词后面的宾语从句中不用if引导 例：Everything depends on whether we have enough money。 ? 宾语从句中有or not时不用if引导. 例：I don’t know whether the movie star will come or not. ? 和不定式连用作宾语时不用if引导. 例：Whether to go there or not hasn’t been decided.
? ? ? ? ?
? ? 在表示： 建议 suggest 、advise、propose; 要求demand 、desire、request； 决定 decide; 命令 order、command、require; 坚决主张 insist; 等动词后跟宾语从句，用（should）+v．（虚拟语气） e g． I suggested that you（should）study hard． He ordered that we should go out at once．
A . 宾语从句必须用陈述语序。 False: He is wondering when can he finish this difficult job. Right: He is wondering when he can finish this difficult job.
B. 有时候可以用it 作形式宾语，而把真正的宾语从句放在后 面。 Bad: I thought that he could finish this job in just two hours impossible. Good: I thought it impossible that he could finish this job in just two hours.
