Unit4 宾语从句在句子中起宾语作用的从句叫做宾语从句。学习宾语从句要抓住三要素:引导词、语序与时态。一、引导词1从句为陈述句,常选择引导词that,that引导宾语从句无意思,不充当句子成分常省略。例句:He told us (that)they would help us through the whole work.2从句为一
12、般疑问句,常选择引导词if或whether,表示“是否”。在 whether or not 构造中不能用 if 交换。例句:I dont know if there will be a bus any more.3. 从句为特别疑问句,常选择what,when,where,which,who,how等的疑问代词、副词作引导词。例句:He didnt tell me when we should meet again.二、推断时态状况:1.主句是一般如今时,从句可以为各种时态。2.主句是一般过去时,从句要用相应过去时态。(留意:从句描绘客观事实、真理、自然现象等,从句时态仍用一般如今时。)例句:
13、He answered that he was listening to me. Father told me that practice makes perfect .爸爸告知我熟能生巧。(客观)三、宾语从句的语序要用陈述句语序陈述句语序,就是主语在前,谓语动词在后。错误:He is wondering when can he finish this difficult job.正确:He is wondering when he can finish this difficult job.留意:宾语从句的否认转移主句的谓语动词是think,believe,imagine,suppose,c
14、onsider,expect,fancy,guess等,并且主句的主语是第一人称而且为一般如今时,从句的否认词一般要转移到主句上来,其反义疑问句一般与宾语从句一样。例如:I dont think he will come to my party.而不能说成I think he wont come to my party.练一练用括号中所给动词的适当形式填空。 1.

Antonio told me he _(read)a book then. 答案:1. was2. was3. went4. might5. was reading(五)if引导的条件状语从句学问点总结引导条件状语从句的连接词主要有:if(假如)、unless(除非)在意思上等于ifnot.或 as long as(只要)等。一、条件状语从句用法1、引导条件状语从句最常用的连词是if,由if引导的条件状语从句表示在某种条件下某事很可能发生。如:If you ask him, he will help you.If
16、 you fail in the exam, you will let him down.2、unless = ifnot. 除非,若不,除非在的时候例如:Lets go out for a walk unless you are too tired.=If you are not too tired, lets go out for a walk.Unless it rains, the game will be played.除非下雨,竞赛将照常进展。3、so/as long as只要例句;You may borrow my book as long as you keep it clea
17、n. 只要你保持书的清 洁,你就可以把我的书借去。So long as youre happy, it doesnt matter what you do. 只要你兴奋,你做什么都没有关系。二、时态问题在条件状语从句中,要留意“主将从现”的规定,即主句用一般将来时,从句用一般如今时表示将来时。eg: I will come to see you if I have time. 我有时间,我就来看你。 练一练 依据中文提示,完成句子。 1. 假如你参与聚会,你将会过得很快乐。 If you _ the party, you _. 2. 假如明天下雨,我们将不去野餐。 If it _ tomorr
