If only和as if所引出的虚拟语气用法
If only和as if所引出的虚拟语气用法
1. if only后的句子用虚拟语气
if only与I wish一样，也是表示与事实相反的愿望的，其后所虚拟语气的时态与wish后所接时态的情况相同。
如：
If only it would stop raining! 雨要是停了就好了。
If only he didn’t drive so fast. 但愿他车没开得那么快。
If only she had had more courage! 她再勇敢一些就好了。
注：if only 通常独立使用，没有主句。
2. as if (as though)从句的虚拟语气
以as if(as though)引导的方式状语从句或表语从句，有时用虚拟语气，若表示与现在事实相反，谓语动词用一般过去时；若表示与过去事实相反，用过去完成时；表示将来的可能性不大，用would (might, could)+动词原形。
如：
He looked at me as if I were mad. 他瞧着我仿佛我疯了似的。
I remember the whole thing as if it happened yesterday.我记得整个这件事就仿佛是昨天发生的。
注：从句所表示的内容若为事实或可能为事实，也可用陈述语气：
It looks as if we’ll be late. 我们似乎要迟到了。
This meat tastes as if it has already gone bad. 这肉吃起来似乎已经坏了。
在现代英语中，有时即使从句内容不是事实，也可能用陈述语气。
如如：
I feel as if [as though] I’m floating on air. 他感到好像漂浮在空中。
另外，还要注意 It isn’t as if…的翻译。
如：
It isn’t as if you were going away for good. 又不是你离开不回来了。

if only用法归纳
if only用法归纳好嘞，以下是为您创作的关于“if only 用法归纳”的文案：咱今天就来好好唠唠“if only”这个短语的用法。
先来说说“if only”常见的第一种用法，它常用来表达强烈的愿望或遗憾，意思是“要是……就好了；但愿……”，而且后面接的句子要用虚拟语气。
比如说，“If only I were taller ”（要是我再高点儿就好了。
）这里用了 were，而不是 was，因为是虚拟语气嘛。
我想起之前教过的一个学生小明，他特别喜欢打篮球，可就是身高不太够，每次看到那些高个子同学在球场上轻松投篮，他就会嘟囔：“If only I were taller I could play basketball better” 那小眼神里满满的都是渴望和无奈，看得我都有点心疼他了。
再说说“if only”引导的虚拟语气中，对过去的虚拟。
要是想表达对过去事情的遗憾，就得用“if only ＋主语＋ had ＋过去分词”这个结构。
举个例子，“If only I had studied harder last term ”（要是我上学期学习再努力点就好了。
）就像我表妹，之前考试没考好，哭着跟我说：“If only I had reviewed all the lessons before the exam ”她那后悔的样子，真是让人又好气又好笑。
还有啊，如果是对将来的虚拟，那就得用“if only ＋主语＋would/could ＋动词原形”。
比如说，“If only he would come tomorrow ”（但愿他明天能来。
）我记得有一次和朋友约好出去玩，结果他临时有事来不了，我心里就想：“If only he could come as planned ”那失落感，别提了！另外，“if only”还能用来强调条件的重要性。
比如说，“If only you listen carefully, you will understand ”（只要你认真听，你就会明白。
