牛津高中英语虚拟语气的全部考点和记忆技巧

虚拟语气的基本内容

【开头引入】

If 如果 (如果有两种可能,有可能发生的，不可能发生的。)

①有可能发生If it rains tomorrow, I will not go to the park.

②不可能发生虚拟语气，例如，如果我是姚明，。。。

虚拟语气表示说话人的愿望，假设，猜测或建议，而不表示客观存在的事实。所以，凡表示与事实不符的假设，想象，愿望时，需用虚拟语气表达。

一、If 引导的虚拟

（一）If 引导的虚拟语气,可用下表表示。

例如：

①与现在事实相反：If I had wings, I would fly over the sea.

②If she were rich, she would buy a bigger house.

If there were no gravity, we would not be able to walk on the earth.

②与过去事实相反：

If You had gone to the party, You would have seen YaoMing. If you had taken my advice, you would not have failed in the exam.

③与将来事实相反：

If he were to tomorrow, We would have the meeting.

If he should come tomorrow, We could go to the park together.

If there were a heavy snow next Monday, we would not go skating.

（二）if虚拟语气条件句的省略倒装。

如果虚拟条件从句中有were, had, should,可把if 省略，把were, had, should 提到主语前面，成为倒装结构。

① If I were you, I would accept the challenges.

----Were I you, I would accept the challenges

② If you had informed me earlier, I wouldn’t have signed the contract.

----Had you informed me earlier, I wouldn’t have signed the contract.

③ If she should be my daughter, I wouldn’t allow her to study abroad.

----Should she be my daughter, I wouldn’t allow her to study abroad.

VIP Tips : Were it not for…“如果要不是…” Had it not been for…“如果当时要不是…”

①Were it not for your help, I would never be a good boss.

要不是你的帮助，我永远成不了一个好的老板。

②Had it not been for you, I would have lost my way.

当时要不是你，我就迷路了。
