concern作为动词最常用的两种用法:
1.to make someone feel worried or upset:
例子:The fact that she spends so much time on her own really concerns me。
2.if a story, book, report etc concerns someone or something, it is about them
例子: This article concerns a man who was wrongly imprisoned
以上两种用法均无法直接跟doing(当然除了doing跟的是后置定语除外)
只有一种情况可以跟doing,但必须加with/about。句型为:concern oneself with or about sth/doing sth本回答被提问者采纳
