主要考试知识点
表示不太可能达成的假设
这种虚拟语气常用于表示一种不太可能达成的或与以后事实相反的假设，一般用于表达一种愿望、建议或不太可能达成的状况。
例句：“If it were to rain tomorrow, the sports meeting would be put off.”在四六级的写作中，特别是在表达假设状况时，会用到这种虚拟语气。比如：“If I were to win the lottery, I would travel around the world.”
例句：“If he were to ask me, I would help him.”在阅读理解中，特别是描述某种假设状况的文章中，会用到这种虚拟语气。比如：“If she were to change her mind, we could try another plan.”
与情态动词连用
在主句中，可以用would/should/could/might等情态动词，表示不一样的语气和可能性。
would：表示意愿或可能性较大
例句：“If I had enough money, I would buy a new car.”
should：表示应该或建议
例句：“If you were in my position, you should think twice.”
could：表示能力或可能性较小
例句：“If he had more time, he could finish the project.”
might：表示较小的可能性
例句：“If it were to be sunny, we might go to the beach.”
容易见到的虚拟语气句型
“If I were to...”：表示“假如我要……”，常用于表达与以后事实相反的假设。
例句：“If I were to win the game, I would be very happy.”在四六级的写作中，特别是在表达假设状况时，会用到这种句型。比如：“If I were to get the job, I would move to a new city.”
“If it were not for...”：表示“要不是……”，用于表示一种与以后事实相反的假设。
例句：“If it were not for your support, I would not be able to continue.”在阅读理解中，特别是描述某种假设状况的文章中，会用到这种句型。比如：“If it were not for the teachers encouragement, I would not have tried again.”
与以后事实相反的虚拟语气的变体
省略if：在书面语中，尤其是正式文体中，可以将if省略，将were/should/were to等助动词提前到句首。
例句：“Were it to rain tomorrow, the sports meeting would be put off.”这种使用方法在四六级的阅读理解中或许会出现，特别是在一些正式的文献或文章中。比如：“Should he ask me, I would help him.”
用“but for”代替“if it were not for”：在表示“要不是……”时，可以用“but for”代替“if it were not for”。
例句：“But for your support, I would not be able to continue.”这种使用方法在四六级的写作中也非常容易见到，特别是在表达感激或假设状况时。比如：“But for the teachers encouragement, I would not have tried again.”
