第二类条件句

型态

在第二类条件句中,if 子句使用的时态是一般过去时,而主要子句的时态是条件式现在时或条件式现在进行时

if 子句(条件/情况) 主要子句(结果)
if + 一般过去时 条件式现在时或条件式现在进行时
If this thing happened that thing would happen.

就如所有条件句,子句的顺序并没有硬性规定。当您要改变子句的顺序时,必须重新安排代词的位置,以及调整标点符号,但意思基本上是一样的。

举例
  • If it rained, you would get wet.
  • You would get wet if it rained.
  • If you went to bed earlier you wouldn't be so tired.
  • You wouldn't be so tired if you went to bed earlier.
  • If she fell, she would hurt herself.
  • She would hurt herself if she fell.

作用

第二类条件句论及不可能或假设性的情况,以及该情况可能会有的结果,这类句子并非根据实际情况。在第二条件句的时间指的是现在或任何时候,而情况是假设的

举例
  • If the weather wasn't so bad, we would go to the park.(但天气太糟所以我们不能去)
  • If I was the Queen of England, I would give everyone a chicken.(但我并不是皇后)
  • If you really loved me, you would buy me a diamond ring.
  • If I knew where she lived, I would go and see her.

「if I were」是正确的,也很普遍;而「if I was」并不属于条件句或虚拟语气的用法。

举例
  • If I were taller, I would buy this dress.
  • If I were 20, I would travel the world.
  • If I were you, I would give up smoking.
  • If I were a plant, I would love the rain.

在第二类条件句中,您也可以在主要子句用情态助词取代 would,以表达肯定程度丶允诺或有关结果的建议。

举例
  • We might buy a larger house if we had more money
  • He could go to the concert if you gave him your ticket.
  • If he called me, I couldn't hear.

条件式现在时

任何动词的现在条件式都是以两个要素组成:
would + 主要动词不定词(不带有 to)

主词 + would + 不定词
He would go
They would stay
条件式现在时,以 To Go 为例
肯定句 否定句 疑问句 否定疑问句
I would go I wouldn't go Would I go? Wouldn't I go?
You would go You wouldn't go Would you go? Wouldn't you go?
He would go He wouldn't go Would he go? Wouldn't he go?
She would go She wouldn't go Would she go? Wouldn't she go?
We would go We wouldn't go Would we go? Wouldn't we go?
They would go They wouldn't go Would they go? Wouldn't they go?
