1.表示与现在事实相反的愿望

构成：主语 + wish (that) + 从句主语 + 动词过去式 （be 一律用were）

例如：I wish I knew everything in the world.我希望我知道世界上所有的事。

I wish that the experiment were a success.我希望这个实验是成功的。

We wish we had wings.我们希望有翅膀。

2.表示与过去事实相反的愿望

构成：主语 + wish (that) + 从句主语 + would/could + have + 过去分词或had + 过去分词

例如：I wish that you hadcome yesterday.我希望你昨天来过。

I wish that I could have gone with you last night.我希望我昨晚能和你一起去。

I didn’t go to the party, but I do wish I had been there.我没有去参加晚会，但是我真的希望我去过那里。

3.表示将来不大可能实现的愿望

构成：主语 + wish (that) + 从句主语 + would/should/could/might + 原形动词

例如：I wish that he could try again.我希望他能再次尝试。

I wish that someday I should live on the moon.

We wish that they would come soon.

II. ASif 引出的虚拟。

As if….表好像……我们经常会利用一下句型来表达不能实现的虚拟状态：It is as if……。 (就好象是……)

As if + 从句， 主句。 （好像…… Sb.+ do…）表达一种假设的条件。而 As if 之后的假设内容的语法结构和wish虚拟的结构一样。

L. 33 A Day to Remember 中原句， “As if this were not enough to reduce you to tears, your husband arrives.” 就利用了和现在事实相反的假设虚拟。北京新东方名师指出，要善于总结出一些学习语法的技巧，如利用对比，举例等方法进行学习。

注：Something is to happened，I'm to face it。
