10. If only引出的从句
If only引出的从句用以表达感叹性的愿望,常译为“要是…就好了”。If only从句经常省略结果主句,且主要用在虚拟语气中,即从句的谓语动词用一般过去时表示现在或将来不可能实现的愿望,或用过去完成时表示过去没有实现的愿望。
If only the rain would stop.
If only I’d listened to my parents.
Note: if only引出的句子偶尔也可使用陈述语气,但考生须注意的是,在各类测试中一般都以用虚拟语气为正确答案。
11. would rather(that)引出的从句
would rather意为“宁愿”,接从句时常省略关系代词that。would rather后的从句要用虚拟语气,即从句谓语动词用一般过去时表示现在或将来的愿望,用过去完成时表示与过去事实相反的愿望。
I’d rather you told me the truth.
I would rather you came tomorrow than today.
I’d rather you hadn’t told me about it.
12. It is (about/high) time (that) 句型
该句型表示“(早)该做…”,其后的定语从句中的谓语动词要用虚拟语气表示。在测试中从句的谓语动词用一般过去时。
It is time that we went to bed.
It is high time that somebody taught you to behave yourself.
