先做一下下面两道试题,如果感觉吃力,请你认真学习本文,如果你感觉简单,答案又正确的话,请直接跳过,不过可能还会吃亏,因为我今天的知识点非常重要,我的讲义里例句都是经典的,许多地方都是意想不到的考点。最好还是认认真真地看看本文吧,嘿嘿。

1、Mary ____ my letter ;otherwise she would have replied before now.

A has received B ought to have received

C couldn't have received

D shouldn't have received

2、where have you been?

I______in the heavy traffic,otherwise I_______here earlier.

A got stuck; would have come

B got stuck ;was

C have got stuck ;would have come

D had got stuck; would come

1、otherwise可表示含蓄虚拟的条件,主句用陈述语气(该声明时态用声明时态),从句用虚拟语气用would have done形式表达.

如:We didn’t know you were in trouble at that time, otherwise we would have given you a hand.

我们当时不知道你遇到了困难,要不然我们会帮助你的.

除了otherwise(否则,要不然)以外,能够表示这种虚拟条件的词和短语还包括:but that(要不是)、without(没有)or(不然)、under...circumstances(在……的情况下)、in the past(在过去)等等.

Luckily he reminded me. Otherwise I'd have forgotten all about it.

亏他提醒了我,要不我早忘了。

He reminded me of what I should otherwise have forgotten.

他提醒了我, 要不然(如果没有提醒我)我就会把这件事给忘了。

His advice has made the design better than it would otherwise have been.

他的建议使得这个设计要比它本该是(如果未采纳他的建议)的样子要好。

My parents lent me the money. Otherwise, I couldn't have afforded the trip.

我父母借钱给我了。否则,我可付不起这次旅费。

We're committed to the project. We wouldn't be here otherwise.

我们是全心全意投入这项工作的,否则我们就不会到这里来了。

2、注意:otherwise与or的区别

otherwise用于表示否定条件,指如果不做某事,就会发生不好的事,含告诫、威胁之意,语气强于 or。

Shut the window, otherwise it'll get too cold in here.

把窗户关好,不然屋子里就太冷了。

Don't move, otherwise I'll kill you [ you'll be shot dead].

不许动,要不我就崩了你。

现在就做,否则就解雇你。

Hands up, otherwise you will be shot.

举起手来,否则就毙了你。

Put your coat on, otherwise you'll catch a cold.

穿上外套,不然你会感冒的。

or词义同 otherwise,但语气较弱,多用于口语,也可与 else 合用。

〔例证〕

Get away, or (else) I'll call the cops.

滚开,不然我就打电话叫警察了。

Hurry up or (else) we'll be late.

抓紧时间,不然的话我们就要迟到了。
