■ success

是个不可数的抽象名词。

• We all strive for success in everything we do.我们无论做什么，都力求成功。
• Sometimes it is difficult to achieve success.有时候取得成功是有点困难的。

但是，也可以代表具体一件办成功了的事，此时就变成为可数名词，可以按需要加上定冠词 the 或不定冠词 a，或是加上 many, few 之类的不定数词。

• Mr. Dolling has had many successes in his long career as a violinist.多林先生在他漫长的小提琴家生涯中多次获得成功。
• The event was a success.这次活动办成功了。
