3. 连接代词who, whom, which等

☛Do you know who (whom) they are waiting for? 你知道他们在等谁吗?

☛Do you know which dress fits her best? 你知道哪件连衣裙最适合她吗?

  学习宾语从句要把握三个要点:连接词、语序和时态。

1. 使用宾语从句,连接词的选择至关重要。有关连接词的选择可遵循以下规则:

(1)如果宾语从句为陈述句,连接词用that。that本身既没有实际意思,也不在从句中作成分,所以口语中常省略。

☛I hope (that) you will write to me as soon as possible. 我希望你尽快给我写信。

 (2)宾语从句为一般疑问句时,连接词用if或whether,可译为"是否"。

☛He asked me if(whether) I would go to Beijing by air. 他问我是否乘飞机去北京。

 (3)宾语从句为特殊疑问句时,连接词用原疑问词。

☛He didn't know how he could get across the river. 我不知道他是怎么过了河的。

2. 从句的语序

  无论原句是陈述句、一般疑问句,还是特殊疑问句,在宾语从句中一律使用陈述语序。

☛The teacher asked if you had finished your homework. 老师问你是否做完作业了。

☛Can you tell us when the sports meeting will begin? 你能告诉我们运动会何时举行吗?

3. 时态的选择

 (1)如果主句是一般现在时,宾语从句可以是任何所需要的时态。

☛I hear a new restaurant will be opened in the city next month. 我听说这个城市下个月将开一个新饭店。

 (2)如果主句是一般过去时,宾语从句要用与其相应的过去的某种时态。

☛She told us she had borrowed the book from the library. 她告诉我们她从图书馆借的这本书。

☛He never told me when he would leave. 他从未告诉我他何时离开。

【特别注意】

  当宾语从句表示的是一个真理或一个永久性的事实时,其时态可不受主句时态的限制,仍用一般现在时。

☛The teacher said millions of other stars are even bigger and brighter than the sun. 老师说数百万行星都比太阳更大、更亮。
