10. If only引出的從句
If only引出的從句用以表達感嘆性的愿望,常譯為“要是…就好了”。If only從句經常省略結果主句,且主要用在虛擬語氣中,即從句的謂語動詞用一般過去時表示現在或將來不可能實現的愿望,或用過去完成時表示過去沒有實現的愿望。
If only the rain would stop.
If only I’d listened to my parents.
Note: if only引出的句子偶爾也可使用陳述語氣,但考生須注意的是,在各類測試中一般都以用虛擬語氣為正確答案。
11. would rather(that)引出的從句
would rather意為“寧愿”,接從句時常省略關系代詞that。would rather后的從句要用虛擬語氣,即從句謂語動詞用一般過去時表示現在或將來的愿望,用過去完成時表示與過去事實相反的愿望。
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
該句型表示“(早)該做…”,其后的定語從句中的謂語動詞要用虛擬語氣表示。在測試中從句的謂語動詞用一般過去時。
It is time that we went to bed.
It is high time that somebody taught you to behave yourself.
