名师讲解：宾语从句的时态
宾语从句的时态
1. 如果主句的时态是一般现在时，宾语从句该用什么时态就用什么时态。即，从句可用所需的任何时态
如：
I don’t think (that) you are right.
Please tell us where he is.
Can you tell me how I can get to the railway station?
He says Mary is playing with the cat .
He says Mary often plays with the cat.
He says Mary will play with the cat.
I think he left yesterday morning.
2. 如果主句的时态是一般过去时，宾语从句只能用相应的过去时态（一般过去时，过去进行时，过去将来时，过去完成时）。例如：
He asked what time it was.
He told me that he was preparing for the sports meet.
He asked if you had written to Peter.
He said that he would go back to the U.S. soon.
He said, “Mary is playing with the cat.” →
He said Mary was playing with the cat.
He said, “he will go back to China soon.” →
He said he would go back to China soon
3. 如果宾语从句所陈述的是客观真理，其时态常用一般现在时，不受主句时态的限制。例如：
Our teacher said that January is the first month of the year.
Scientists have proved that the earth turns around the sun.
The teacher said, “the moon moves around the sun.”
→ The teacher said that the mo on moves around the sun.
He said, “light travels much faster than sound.”
→ He said light travels much faster than sound.
4、当主句为Could you (please) tell us-----?时，只表示语气，而不表示过去时态。•考点归纳——宾语从句的时态
