宾语从句三要素：连接词、语序、时态

宾语从句的连接词

1. 连词that，起连接作用，在从句中不作句子成分，也无词汇意义，在口语中常被省略。

He knew (that) he should work hard.

2. 连词if/whether，起连接作用，在从句中不充当任何句子成分，意为“是否”，不能省略，在口语中多用if。

Tom don ’t know if/whether his grandpa liked the present.

He asked me whether I was coming or not.

一般情况下，if和whether可以互换，但以下3种情况只能用whether：

① 在不定式前

Whether to go there or not hasn ’t been decided.

② 在介词后

It depends on whether it is going to rain.

③ 与or not连用

They are talking about whether to go there or not.

3. 疑问词在句中既起连接作用，作句子成分，又有实际意义：

连接代词：who, whom, whose, what, which

连接副词：when, where, why, how

who在从句中作主语、表语；

whom在从句中作宾语；

whose在从句中作定语；

what和which在从句中作主语、宾语、表语或定语；

when, where, why, how在从句中分别作时间状语、地点状语、原因状语和方式状语。

人称和时态变化

1. 陈述句变为宾语从句时，要注意人称和时态的变化，语序不变。

She said, “I will leave a message on the desk.”

→ She said she would leave a message on the desk.

2. 一般疑问句和特殊疑问句变为宾语从句时，也要注意人称和时态的变化，后接陈述语序。

“Where are the tickets?” I asked him.

→ I asked him where the tickets were.
