表语从句的时态应根据主句的时态来确定。如果主句的谓语动词为现在时态,表语从句一般使用现在时态;如果主句的谓语动词为过去时态,表语从句一般使用过去时态;如果主句的谓语动词为将来时态,表语从句一般使用将来时态。掌握好表语从句的时态用法,可以提高英语表达的准确性。
现在时态
当主句的谓语动词为现在时态时,表语从句的谓语动词一般使用与主句相同的时态。例如:
- My favorite food is pizza.(我的最爱是披萨)
- The fact is that he is always late.(事实是他总是迟到)
过去时态
当主句的谓语动词为过去时态时,表语从句的谓语动词一般使用过去时态。例如:
- His wish was that he could go back to his hometown.(他的愿望是能回到故乡)
- The rumor was that she had quit her job.(传言是她已经辞职了)
将来时态
当主句的谓语动词为将来时态时,表语从句的谓语动词一般使用将来时态。例如:
- My hope is that I will pass the exam.(我的希望是我能通过考试)
- The plan is that we will meet at the station tomorrow.(计划是我们明天在车站见面)
