 opportunity, occasion, chance这组词的一般含义是"时机"或"机会"。不管在口语中或者在文学作品中,这几个都是常用的词。

(1)opportunity表示某时机符合自己想干某事的意愿、目的、雄心甚至野心。常与动词have, get, find, create, take, miss等连用。

  例如:

They are waiting for an opportunity to take action:他们正在伺机而动

to avail oneself of the opportunity to say a few words:借此机会说几句话

I took the opportunity of visiting my aunt while I was in Shanghai.

我利用在上海的机会探望了我的姑姑。

Perhaps there is an element of truth in both these pictures, but few of us have had the opportunity to find out.

或许这两种想象中都有一定的真实成分,但是我们中很少有人有机会去发现它。

(2)occasion含有opportunity所能表达的这样一层意思:某时机能激发或唤起某人的某种行为,

  如:

在"必要时"一语中便包含着激发某行为的时刻,此语可译为When occasion demands...;"这不是哭泣的时候。"这句话可译为It's no occasion for crying。在to have no occasion to do...固定词组中,occasion之所以能够引申为reason或cause的含义,也是与occasion的上述基本词义有关的。

  再如:

This sort of thing is usual on occasions like this. 这类事情在这种场合是常见的。

This is not an occasion for laughter.

这不是笑的时候。(指不适合于笑,或不是笑的场合。)

(3)chance表示幸运或偶然的时机,还可以指可能性的程度。

  例如:

What are your chances of being promoted?你升职的可能性有多大?

N o one discovers a rarity by chance. 侥幸发现一件珍品的人是没有的。

  三、重点句型

1.-What's the matter?

-I've got a pain here.
