宾语从句详细讲解，宾语从句的时态法则

宾语从句具体介绍？

一、 宾语从句要点之时态的呼应

1.假设主句是大多数情况下目前时、大多数情况下以后时或祈使句时，宾语从句可按照情况使用各自不同的时态。比如:

I hear she is here today(she was here yesterday/ she will be here tomorrow.)

2.假设主句是大多数情况下过去时,宾语从句应使用过去时态的某种形式。

比如:

He said he was watching TV(he had

swent the foor/ he would nlay foothat after school)。

3.如宾语从句所叙述的是客观事实、自然情况或科学真理等，从句不受主句时态限制，仍用大多数情况下目前时。

比如:

Our teacher told us that light travels faster than sound.

二、宾语从句要点之引导词的使用

1.当宾语从句由陈述句变化而来时，用 that来引导从句，that常无详细意义，大多数情况下可省略。

比如:

Lin Tao thought(that)the TV play was very boring.

2.当宾语从句是由大多数情况下疑问句变化而来时，要用if或whether来引导从句。

比如:

David asked his mother if/ whether she

liked the dinner last night.

3.当宾语从句是由特殊疑问句变化而来时，原句中的疑问词充当连接代词(如who, whose, what, which)或连接副词(如when, where, why, how),引导宾语从句。比如:

Do you know what we can do on the island?

I dont know why Jane was late for school this morning.

三、宾语从句要点之语序的陈述化

宾语从句大多数情况下要用陈述句语序。

比如:

When did he leave? I want to know. | want to know when he left.

Does the shop close at six every day? Do you know? →Do you know if/ whether the shop closes at six every day?

当主句的谓语动词为think, believe,

suppose等动词，且主语为第一人称时，从句的否定要转移到主句上。比如:

I dont believe he is here on time is he?

I dont think Tom is the best student in his class, is he?
