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

你需要理解句子意思再来做分析而不是只是看单词

have problems 和 don't know how to be happy 其实是并列的关系，他们所指一样
因此用 and

Have you ever noticed Have you ever ____Australia? Have You Ever --Have you ever traveled on___train? Have you ever seen that movie? HAVE YOU EVER COME ACROSS THIS？ Have you ever been to Niagara-------(fall)? 选择：Have you ever been to city? Have You Ever Seen the Rain 歌词 Have you ever been to Disneyland?
