知识点总结

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、语序和时态。

一、.引导词

1.从句为 陈述句，常选择引导词that，that引导宾语从句无意义，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.从句为一般疑问句，常选择引导词if或whether，表示"是否"。在 whether … or not 结构中不能用 if 替换。例句：I don’t know if there will be a bus any more.

3. 从句为特殊疑问句，常选择what,when,where,which,who ,how等的疑问代词、副词作引导词。 例句：He didn’t tell me when we should meet again.

二、判断时态情况：

1.主句是一般现在时，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。

注意：从句描绘客观事实、真理、自然现象等，从句时态不受主句时态限制，仍用一般现在时。

例句：He answered that he was listening to me.

Father told me that practice makes perfec t .

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 whe n he can finish this difficult job.

注意：宾语从句的否定转移

主句的谓语动词是think,believe,imagine,suppose,consider,expect,fancy,guess等,并且主句的主语是第一人称而且为一般现在时,从句的否定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 致. 例如 ;I don’t think h e will come to my party.而不能说成I think he won’t come to my party.

常见考法

对于宾语从句的考查，多以单 选的形式考查学生灵活运用的能力。一般情况下，常从引导词的选择、时态的一致性及从句的陈述语序方面考查。

典型例题：Please tell me ______ last year.

A.where does y our sister work B where did your sister work

C .where your sister works D where your sister worked

解析：本题考查对宾语从句的掌握。宾语从句要用陈述语序，所以排除A和 B;last year 表示过去时 ，所以排除 C 。

答案：D

误区提醒

宾语从句的语序要用陈述句 语序 ，但要注意当疑问词为主语时，句式为：疑问词+谓语+其他 ，问句和陈述句语序一样。

典型例题：I didn’t know ?

A. What wrong was with her B.what was wrong with her

C .wh at wrong is with her D.what is wrong with her

解析：主句是一般过去时，从句要用相应过去时态，所以排除C和D;在what was wrong with her中，what作主语，所以问句本身又是陈述句语序，不用变化。

答案： B
