题目内容：

关于succeed/ success in doing sth.
Beijing has already succeeded in hosting the 2008 Olympic Games.
It is famous for its success in helping homeless people return to a normal life.
两个句子都是表达成功做某事为什么一个用动词succeed,一个用名词success?乱.

优质解答

看到前面的has没~have+done（动词过去分词）所以要加动词
its翻译一下是它的,所以这里缺少的是名词
succeed动词,success名词,successful形容词
