Let’s ask what time the band starts.
(一)连接词。特殊疑问句作宾语从句时不 需要再加连接词,疑问词就是连接词,并且 不能省略。
语序
不管什么类型的宾语从句,总是用陈述句 语序,即从句的连接词后是主语、谓语、 宾语的语序。当连接词做主语时,后面直 接跟谓语和宾语。
I shall write to you what I want to say. 我会写给你我想说的话。
I don’t know who wants to borrow these magazines.
3. I don’t know __w_h__et_h_e_r__ to go or stay. 4. ____I_f ___ that is true, what should we do?
5. _W__h_e_th_e_r_ they will ever become future Olympic champions only time will tell.
I ask what you are doing now. 我问你现在正在干什么?
(二)词序。用“特殊疑问词+陈述句”的 词序,与一般疑问句变宾语从句时基本相同。
He didn’t tell me when we would meet again.
他没告诉我什么时候我们再见面。
连接词
宾语从句是由陈述句转化成的,连接词用 that;
3. “两副面孔” if 和 when 等既能引导宾语从句,又能引导状
语从句。因此,碰到此种情况要认真分析。当 从句表示将来时,若引导的是宾语从句,它们 的时态常用一般将来时;若引导的是状语从句, 它们的时态常用一般现在时代替将来时。
If it rains tomorrow, I won’t come.(时间状 语从句)
时,宾语从句可根据句意的需要而选用 任何一种时态。
(2)若主句是一般过去时时,宾语 从句用表示过去的某种时态。
1. 当宾语从句的内容是客观事实或科学真理 时,不论主句是什么时态,从句都用一般现 在时态。
2. 当主句谓语动词为think,suppose,guess, believe等, 并且主语为第一人称时,从句的否 定词应转移为对主句谓语动词的否定, 即否定 前移。
Cloud you tell me how to get to the post office?
Can you tell me when the band starts playing this evening?
I wonder where we should go next.
I wonder when the park closes today.
我不知道谁想借这些杂志。
时态
主句和从句的时态须保持一致。如果主句 为一般现在时,从句可根据需要选择各种 时态;如果主句是一般过去时,从句只能 用过去的某种时态(包括一般过去时、过去 进行时、过去完成时、过去将来时等)。
I’m sorry to hear that your mother is ill. 听说你母亲病了,我很难过。
She didn’t know that Tom had left for Shanghai.
她不知道汤姆已去了上海。
