如果转述动词是现在时，或原陈述句的内容对现在来说依然是如此，就不必改变时态。例如：

• He says he has missed the train but he'll catch the next one.
• We explained that it is very difficult to find our house.

 

这些情态助词在转述句并不会改变：might, could, would, should, ought to

• We explained, "It could be difficult to find our house." = We explained that it could be difficult to find our house.
• She said, "I might bring a friend to the party." = She said that she might bring a friend to the party.
