网友“douya0808”：

之前给你回答了许多问题，没见采纳，不知满意否？如不清楚，可以追问，但希望你不要置之不理。

现在回答你的问题：

【答】表示与将来情况不符或相反的虚拟语气，在条件中可以使用如下表达，意义基本相同：

1. If you succeeded +主句 （succeed 不能用一般现在时）

2. If you should succeed +主句

3. Should you succeed +主句（句2的倒装格式）

4. If you were to succeed +主句

5. Were you to succeed +主句（句4的倒装格式）

【注意】在虚拟条件句中，如果含有should, were, had等助动词，可以将if 去掉，然后把should, were, had提到主语前面，形成倒装句。

If she should come tomorrow, I would treat her to a big meal.

→Should she come tomorrow，I would treat her to a big meal.

如果她明天来的话，我请她吃大餐。

If he were to try once more, he might succeed.

→ Were he to try once more, he might succeed.

如果他再尝试一次,他就有可能成功。

If you had taken my advice, you wouldn't have failed in the examination.

→Had you taken my advice，you wouldn't have failed in the examination.

如果你听了我的建议，你就不会考试不及格。
