Have you ever had problems in you life and don't know how to be happy?

问题描述:

Have you ever had problems in you life and don't know how to be happy?
and表并列,但had和don't明显不同啊.这是怎么回事呢?

have 与don't都是动词
股用and
have problems 和 don't know how to be happy 不是并列
Have you ever had problems与don't know how to be happy才是
