宾语从句 主句是过去时态 从句要用什么时态
1、宾语从句中主句是过去时态,宾语从句必须是一种过去的时态。例如:
She asked me if I knew whose pen it was.她问我是否知道这是谁的钢笔。
He said that he could finish his work before supper.他说他会在晚饭前完成工作。
2、当表示客观事实或普遍真理的句子做宾语从句时,任何时候都用一般现在时。例如:
The teacher said that the earth goes round the sun.老师说过地球绕着太阳转。
3、当主句是现在时态时,宾语从句可以根据需要使用任何时态。例如:
I don't know when he will come back.我不知道他将何时回来。
He tells me that his sister came back yesterday.他告诉我他姐姐昨天回来了。

需要注意的是,任何从句都使用陈述句语序,宾语从句当然也不例外。宾语从句的分类:
1、动词宾语从句:顾名思义,它是位于动词后面的宾语从句。例如:He asked whose handwriting was the best in our class.他问我们班上谁的书法最好。
2、介词宾语从句:顾名思义,它是位于介词后面的宾语从句。例如:I agree with what you said just now.我同意你刚才说的话。
3、形容词宾语从句:顾名思义,它是位于形容词后面的宾语从句。例如:I am afraid that I will be late. 恐怕我要迟到了。
一、如果主句的谓语动词是一般现在时或一般将来时,宾语从句中的谓语动词可根据意义的需要,使用任何一种时态。如:
1) Could you tell me when you will come again? 你能告诉我你什么时候再来吗?
2) I don't know if he arrived yesterday. 我不知道他是否昨天到了。
3) Could you tell me what you were doing at eight last night? 你能告诉我你昨晚八点在干什么?
二、如果主句的谓语动词为一般过去时,从句应用相应的过去时态。
1. 如果主句中的谓语动词所表示的动作与从句的动作同时发生,则从句应用过去进行时或一般过去时。如:
1) She said that she was working on the Internet. 她说她在上网。
2) He told me that he knew the computer technology very well. 他对我说他精通电脑技术。
2. 如果从句的动作发生在主句的动作之前,则从句应用过去完成时。如:
1) He didn't know what they had come here for. 他不知道他们到这里来的目的。
3. 如果从句的动作发生在主句的动作之后,则从句应用过去将来时。如:
1) Jim told me he would spend his holidays in the south. 吉姆告诉我他将到南方度假。
使用宾语从句的时态还应注意下列特殊情况:
一、如果宾语从句中有明确表示过去的时间状语,不论主句用什么时态,从句一律用过去时。如:
1) She said she came to work here in 1998. 她说她是1998年来这里工作的。
2) The teacher told us that the war broke out in the winter of 1923. 老师告诉我们那场战争爆发于1923年的冬天。
二、如果宾语从句表示客观真理、科学原理、自然现象、现阶段存在的客观事实、现在经常性或习惯性的动作、谚语、格言等,不论主句用何种时态,从句一律用一般现在时。如:
1) Our teacher told us that light travels much faster than sound. 我们老师对我们说光比声音传播要快得多。
2) The mother told his son that two and three is five. 母亲告诉孩子二加三等于五。
3) We all knew that a friend in need is a friend indeed. 我们都知道,患难之交才是真朋友。
4) He told me that his father is an English teacher. 他告诉我他父亲是名英语老师。
He said he was happy. He told me he had done his homework.
但是,如果从句表达的客观事实、普遍真理,从句仍然使用一般现在时。如:
The teacher said the earth goes around the sun.
he said that he didn't
know anything about it.
he said the sun comes out from the east.
