一、用法说明

动词wish后接宾语从句时，从句谓语要用虚拟语气。若要表示与现在事实相反的愿望，从句谓语用一般过去时或过去进行时;若表示与过去相反的愿望，从句谓语用过去完成时或would / could+have +过去分词;若表示将来没有把握或不太可能实现的愿望，用would (could)+动词原形。

如：

I wish I were not so busy. 但愿我不那样忙碌。

I wish I were [was] better looking. 要是我长得漂亮些就好了。

She wished she had stayed at home. 她后悔的是她当时要是留在家里就好了。

I wish you would go with us tomorrow. 要是你明天同我们一起去就好了。

I wish you wouldn’t look down on this kind of work. 我希望你不要看不起这种工作。

This watch has gone wrong. I wish I had bought a better make. 这只表坏了，我真愿意我买的是好一点的牌子。

I wish you wouldn’t smoke any more. 我希望你不再抽烟了。

I wish you would be more respectful to your father. 我希望你对你父亲更尊敬些。

I wish I could be of some use. 我希望我能有什么用处。

二、特别注意

从句的时态只与从句所指的时间有关，而与wish的时态无关，比较：

I wish I were rich. 要是我现在有钱就好了。

I wish I had been rich. 要是那时我有钱就好了。

I wished I were rich. 当时我后悔自己没有钱。

I wished I had been rich. 当时我后悔自己曾经没有钱。

三、if only后的句子用虚拟语气

if only 与 I wish一样，也用于表示与事实相反的愿望，其后所虚拟语气的时态与 wish 后所接时态的情况相同：

If only she had had more courage! 她再勇敢一些就好了。

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 I were [was] better looking. 要是我长得漂亮些就好了。

If only I had listened to my parents! 我要是当时听了父母的话就好了。

If only she would go with me! 她要是愿意和我一道去就好了!

【友情提示】if only 通常独立使用，没有主句。
