宾语从句可以分为三类（1）动词的宾语从句1.1 大多数位于动词后面 Eg：I hope you can join us in the game.1.2 有些是“动词+副词”后 Find out / point out / figure out / turn out/ figure out Eg：Can you figure out what the poet really means in this poem?1.3 有些动词短语后面 Make sure / make up one’s mind / keep in mind Eg：we should keep in mind that sports can be a great boost to our health.(2) it 作形式宾语代替宾语从句第一类动词： find/ feel/ think/ consider/ make / believe/ guess/ suppose /assume等后面有宾语不足语时，需要用it 作形式宾语而将that引导的真正的宾语从句后置。 Eg：I think it necessary that we do some sporting.第二类动词： 带宾语从句时需要在从句前面加it。这类词：hate / like/ dislike/ appreciate/ depend on/ see to / Eg: I hate it when they talk without considering other’s feeling.但是如果宾语从句是WH-类引导的，其后面有to be 短语作宾语补足语，不可以用it 代替。 We all consider what you said to be unbelievable. (right) We all consider it to be unbelievable what you said .(wrong)(3) 形容词后的宾语从句Adj: sure / certain/ glad/ pleased/ happy / afraid / sorry 等等。Eg：I am not sure whether you will come or not.3. 宾语从句的语序问题（1）要把疑问语气改为陈述语气 Eg：I could not understand why you refused this good opportunity.(2) 宾语从句引导词that 的省略问题 That在一般情况下可以省略，但在一下情况下不可以省略。 a. 一个动词带有两个或多个并列的宾语从句，第一个that可以省略，第二个和以后的都不可以省略。 Eg：Our parents tell us that we should be honest and that we need learn how to share our feelings with others and that we must know how to learn from others. b. 宾语从句是双宾语中的直接引语 Eg：lily told me that she would not come to school tomorrow. c. 有it 作形式宾语 Eg：we all consider it important that children need enough sleep.(3)宾语从句的否定转移 条件：1 主语是第一人称 2 谓语动词是think/ believe / suppose/ imagine/ guess / expect 意义：“主句否定形式，从句否定意义” Eg: I don’t believe that you are a good guy.(4)宾语从句的时态 宾语从句的谓语动词时态通常受到主句时态的影响 1.（主现，从不变）主句为一般现在时态，宾语从句根据需要选择时态。 Eg：I know that you did not finish your homework yesterday. 2.（主过，从过）主句为一般过去时态，宾语从句选择与过去有关的时态。 Eg：he told me that he had been to America .3.(主过，从真理现)主句为一般过去时态，宾语从句如果是客观事实和永久不变的真理，用一般现在时态。 Eg：My mother once told me that the sun rises in the east and sets in the west.(5)运用虚拟语气的情况 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） |
