success既是可數(shù)名詞也是不可數(shù)名詞。success的基本意思是“成功，成就，勝利”，是抽象名詞，不可數(shù)，也不可加不定冠詞a修飾。success還可作“成功的事或人”“一次成敗”解，這時為可數(shù)名詞，不能與冠詞連用。

succeed的用法

他的計劃成功了。

誤：His plan was succeeded.

正：His plan succeeded.

析：succeed 表示“成功”，是不及物動詞，因此不能用于被動語態(tài)。

他終于把那個問題解決了。

誤：At last he succeeded to solve the problem.

正：At last he succeeded in solving the problem.

析：表示做某事做成功了，succeed 后通常不接不定式，而接 in doing sth。

又如：He succeeded in getting the job.（他謀到了那份工作），She succeeded in (passing) the exam.（她考試及格了）

失敗是成功之母。

誤：Failure is the mother of successes.

正：Failure is the mother of success.

析：success 表示抽象意義的“成功”，是不可數(shù)的；表示具體意義的“成功的人或事”, 則是可數(shù)的。比較：Success does not usually occur early.（大器晚成），His new book was a great success.（他新出版的書獲得了巨大成功）。再比較：He has had great success in business.（他事業(yè)上很成功），He was a great success in business.（他事業(yè)上很成功）。

你說服她改變主意了嗎?

誤：Did you have any success to persuade her to change her mind?

正：Did you have any success in persuading her to change her mind?

析：have success in doing sth＝做某事有結果或效果。又如：What success did you have in finding a new job?（你想找份新工作結果如何?）
