来源： 作者：admin (查看评论)
If only the weather were finer！但愿天气更好一点儿！
If only I had passed the exam！我要是通过考试就好了！
If only mother could be here！要是妈妈能在这儿就好了！
if only有时也引导条件从句，这时相当于 if的强化形式。例：
The librarian promised to get the book for me if only she could remember who last borrowed it．图书馆管理员许诺，要是她能记起谁最后借的那本书，她就给我找来。
8．in case，lest／for fear that之后的从句中，谓语一般用（should ＋）动词原形形式。例：
He took an umbrella with him in case／lest／for fear that he（should）be caught in the rain．他带了雨伞，以免遭雨淋。
9．in order that／so that之后的从句中。谓语常用may／might／could／should ＋动词原形形式。
I live so that others may live better．我活着为的是使别人活得更美好。
They are climbing higher in order that they should／might／could get a better view．他们正往高处爬，以便看得更清楚。
10．It's time之后的从句中。谓语动词一般用过去时态形式。例：
It's（high）time we did something．是我们该（马上）做点儿什么事的时候了。
It's time we asked for that sum of money．是我们该要那笔钱的时候了。
11．公式化语句中。如：come what may（无论发生什么事），be that as it may（即使如此）等。例：
Come what may，we'll go ahead with our plan．不管发生什么情况，我们都要推行我们的计划。
Be that as it may，we'll have nothing to lose．即使如此，我们也不会失去任何东西。
12．带感情色彩的语句中。表示惊异、惶恐、怀疑等。谓语常用should ＋动词原形或 should ＋动词完成式（表已发生动作或情况）。例：
a）think，expect，believe等动词后。例：
I don't expect that he should have failed．我没想到他竟然失败了。
b）It's a pity／shame，it's strange，I'm surprised／disappointed等结构后。例：
It's strange that he should feel so angry．他如此生气，真令人奇怪。
We are disappointed that he should be so stupid．他这么愚笨，我们真感到失望。
