英语宾语从句的时态通常取决于主句的时态。如果主句是一般现在时、一般过去时或一般将来时,宾语从句通常要用相应的时态来表示。
例如:
- I know that he is coming tomorrow.(我知道他明天要来。)
- She asked if I had finished my homework.(她问我是否已经完成了作业。)
- They wonder if they will win the game.(他们想知道他们是否会赢得比赛。)
当主句是进行时态时,宾语从句可以使用任何时态。例如:
- He says that he is studying for his exams.(他说他正在为考试而学习。)
- She knows that she needs to work harder.(她知道她需要更加努力工作。)
- We hope that it won't rain tomorrow.(我们希望明天不会下雨。)
需要注意的是,当主句和从句中的动词形式不一致时,需要使用适当的时态来保持一致性。例如:
- She told me that she was tired yesterday.(她昨天告诉我她很累。)
- He said that he had already eaten breakfast when I called him this morning.(当我今天早上给他打电话时,他说他已经吃过早餐了。)
