NMET完形填空所选文章都堪称,其逻辑必是上下贯通,其脉络也必是自然有序,令人信服。下面就为大家带来了中考英语语法题型大攻略,我们一起来看看吧!

  要是我们那时早点找到他的话,我们可能会把他救活的。(可能性)

  If our documents had been in order we could have left at once.

  要是我们的证明文件都齐备的话,我们那时就能够马上走。(能力或允许)

  2 可以用条件完成进行时:

  At the time of the accident I was sitting in the back of the car,because Tom’s little boy was sitting beside him in front.If Tom’s boy had not been there I would have been sitting in front.

  事故发生的时候,我坐在车子的后座,因为汤姆的小儿子坐在前边他的身旁。要是汤姆的孩子没坐在那里的话,我就会坐在前面了。

  3 可以在if从句中用过去完成进行时:

  I was wearing a seat belt.If I hadn’t been wearing one I’d have been seriously injured.

  我当时系了安全带。要是没有系上的话,我就会受重伤了。

  4 可以把类型2和类型3结合起来:

  The plane I intended to catch crashed and everyone was killed.If I had caught that plane I would be dead now/I would have been killed.

  我原想赶乘的那架飞机坠毁了,所有乘客都遇难身亡。要是我赶上了那架飞机,我也就没命了/我就会摔死了。(类型 3)

  If I had worked harder at school I would be sitting in a comfortable office now;I wouldn’t be sweeping the streets.

  要是在上学时学习再努力一些,我现在就会坐在舒适的办公室里,而

  不会是在扫大街了。(但我上学时不努力,因而我现在在扫大街。)

  5 had可以位于句首并省略if:

  If you had obeyed orders this disaster would not have happened.相当于:

  Had you obeyed orders this disaster would not have happened.

  要是你当时服从了命令,这场灾难就不会发生了。

  托福语法:if,even if,whether,unless,but for

  even if(=even though即便)

  请比较下面两个例句:

  You must go tomorrow if you are ready.

  如果你准备好了,明天你必须走。

  You must go tomorrow even if you aren’t ready.

  哪怕你没有准备好,明天你也得走。

  whether…or(=if…or是否)

  You must go tomorrow whether you are ready or not.

  无论你明天是否准备好了,你都必须走。

  unless+肯定动词(=if+否定动词除非)

  Unless you start at once you’ll be late.相当于:

  If you don’t start at once you’ll be late.

  除非你立即动身,否则你就会迟到。

  Unless you had a permit you couldn’t get a job.相当于:

  If you hadn’t a permit you couldn’t get a job.

  除非你有执照,否则你就找不到工作。

  注意下面两个例句间的区别:

  (a) Don’t call ′me if you need help.

  如果你需要帮助的话,别打电话找我。

  (b) Don’t call me unless you need help.

  除非你需要帮助否则别打电话找我。

  在例句(a)中,即使在对方需要帮助的时候,说话人也不愿意去帮助对方。在例句(b)中,在对方需要帮助的时候,说话人愿意帮助对方,但说话人不愿意对方在不要紧的时候打电话找自己。

  unless+he’d/you’d like/prefer等通常可用来代替 if he/you wouldn’t like等:

  I’ll ask Tom,unless you’d prefer me to ask/unless you’d rather I asked Bill.

  我去问汤姆,除非你宁愿叫我去问比尔。

  but for(=if it were not for/if it hadn’t been for不然)

  My father pays me fees.But for that I wouldn’t be here.

  我父亲给我一笔补贴费。不然我就不会在这里了。

  汽车出毛病了。要不是那个我们会及时赶到的。

  otherwise(=if this doesn’t happen/didn’t happen/hadn’t happened否则)

  We must be back before midnight; otherwise we’ll be locked out.

  我们必须在午夜之前赶回去,否则我们就会被锁在门外。相当于:
