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”這部分是對(duì)過去情況的虛擬表達(dá)。它表示的是“我本可以擁有世界上最美好的生活，但實(shí)際上并沒有”。

?“instead I got a little piece of my ear”這部分使用了過去時(shí)“got”，它描述的是過去發(fā)生的實(shí)際情況，即“但我的耳朵卻少了一塊（因某種原因受到損傷）。

用于 if 引導(dǎo)的非真實(shí)條件句

e.g.

①If you had come yesterday, you would have met Georgia. （與過去的事實(shí)相反）

如果你昨天來,你就會(huì)碰到喬治亞了。

②If I were you, I would choose to work in a big city.（與現(xiàn)在的事實(shí)相反）

如果我是你，我會(huì)選擇在大城市工作。

③If it snowed/should snow/were to snow tomorrow, our plan would be postponed.（與將來的事實(shí)相反）

如果明天下雪，我們的計(jì)劃就得推遲。

試總提醒?主句中的should通常用于第一人稱，would／could可以用于各種人稱。

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．

用于含蓄條件句

在表示假設(shè)的虛擬語氣中，有時(shí)假設(shè)的條件并不以條件從句的形式出現(xiàn)，而是通過上下文或句中內(nèi)在的邏輯關(guān)系，或用其他形式表達(dá)出來，這就是“含蓄條件句”。

常用的有以下幾種方式??

1??介詞或介詞短語，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．

2??連詞，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．

試總提醒?由lest，for fear that和in case引起的從句中謂語動(dòng)詞多用“should+動(dòng)詞原形”，但也可以不用虛擬語氣，而用動(dòng)詞的陳述語氣形式。

3??分詞短語United（等于If they had been united）, they wouldn’t have been defeated.

4??動(dòng)詞不定式短語To hear him speak English, one would think him an Englishman.

5??名詞短語和“名詞＋and”結(jié)構(gòu)

A diligent student would have worked harder.

One step further and you would be dead.

6??定語從句Anyone who had been in your position would have done the same.

7??形容詞及其比較級(jí)A more careful person would not have made so many mistakes.

8??獨(dú)立主格結(jié)構(gòu)或由 with 引導(dǎo)的復(fù)合結(jié)構(gòu)All things considered, the price would be reasonable.

用于混合條件句

條件從句表示的動(dòng)作與主句表示的動(dòng)作在時(shí)間上不一致的叫混合條件句 （錯(cuò)綜時(shí)間條件句）。

其主句和從句的謂語動(dòng)詞應(yīng)根據(jù)各自所指的時(shí)間選用適當(dāng)?shù)男问剑?/span>一般從句指過去，主句指現(xiàn)在或?qū)?；或從句不指某一特定時(shí)間，主句指過去；或從句用虛擬語氣，主句用陳述語氣或祈使語氣。

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.

虛擬條件句的倒裝

在虛擬條件句中，如果從句部分含有 were, should 或 had，可將 if 省略，were, should 或 had置于從句句首，使用倒裝。

Were they here now, they could help us.

Should it rain, the crops would be saved.
