I could have had the greatest life in the world,instead I got a little piece of my ear.

?“I could have had the greatest life in the world”这部分是对过去情况的虚拟表达。它表示的是“我本可以拥有世界上最美好的生活，但实际上并没有”。

?“instead I got a little piece of my ear”这部分使用了过去时“got”，它描述的是过去发生的实际情况，即“但我的耳朵却少了一块（因某种原因受到损伤）。

用于 if 引导的非真实条件句

e.g.

①If you had come yesterday, you would have met Georgia. （与过去的事实相反）

如果你昨天来,你就会碰到乔治亚了。

②If I were you, I would choose to work in a big city.（与现在的事实相反）

如果我是你，我会选择在大城市工作。

③If it snowed/should snow/were to snow tomorrow, our plan would be postponed.（与将来的事实相反）

如果明天下雪，我们的计划就得推迟。

试总提醒?主句中的should通常用于第一人称，would／could可以用于各种人称。

①Were I to do the work，I should do it some other day．

②If I had his telephone number, I would call him now．

③If he had worked hard, he would have been in New York now．

用于含蓄条件句

在表示假设的虚拟语气中，有时假设的条件并不以条件从句的形式出现，而是通过上下文或句中内在的逻辑关系，或用其他形式表达出来，这就是“含蓄条件句”。

常用的有以下几种方式??

1️⃣介词或介词短语，如but for，without，in case of, under，with，in等。

But for their help，we could not get over the difficulties．

Without music，the world would be a dull place．

2️⃣连词，如or，otherwise，but，in case，lest，for fear that，so that等。

We took a taxi to the airport．Otherwise we should have been late．

He felt very tired yesterday，or he would have attended the party．

试总提醒?由lest，for fear that和in case引起的从句中谓语动词多用“should+动词原形”，但也可以不用虚拟语气，而用动词的陈述语气形式。

3️⃣分词短语United（等于If they had been united）, they wouldn’t have been defeated.

4️⃣动词不定式短语To hear him speak English, one would think him an Englishman.

5️⃣名词短语和“名词＋and”结构

A diligent student would have worked harder.

One step further and you would be dead.

6️⃣定语从句Anyone who had been in your position would have done the same.

7️⃣形容词及其比较级A more careful person would not have made so many mistakes.

8️⃣独立主格结构或由 with 引导的复合结构All things considered, the price would be reasonable.

用于混合条件句

条件从句表示的动作与主句表示的动作在时间上不一致的叫混合条件句 （错综时间条件句）。

其主句和从句的谓语动词应根据各自所指的时间选用适当的形式，一般从句指过去，主句指现在或将来；或从句不指某一特定时间，主句指过去；或从句用虚拟语气，主句用陈述语气或祈使语气。

If you had asked him yesterday, you would know what to do now.

If the weather had been more favourable, the crops would be growing better.

虚拟条件句的倒装

在虚拟条件句中，如果从句部分含有 were, should 或 had，可将 if 省略，were, should 或 had置于从句句首，使用倒装。

Were they here now, they could help us.

Should it rain, the crops would be saved.

Had you come earlier, you would have got the ticket.
