句子解析,he has experienced the ups and downs of life
这里为什么用has而不用had?

have +分词表示现在完成时,表示这些事情对他还有影响.
had +分词表示过去完成时,在这个句子里如果他去世了就用had,这里是he,所以用has,用has表示他还没有去世,只是说明很多事情经历过.

他已经经历了生活的大起大落。
“他“还没有死，从过去的某一点到现在，用现在完成时。

这是现在完成时
have+过去分词即 have experienced
但是he 是第三人称所以把have改成 has
即 has experienced
翻译他经历了人生的大起大落

要记得,如果想用HAD 必须有个修饰的词(表示过去时态的词)或者有从句限制

他已经经历了生活的大起大落

正如楼上各位解释的，had done是过去完成时态，是相对于过去之前的时态。注意这是一个"相对"的概念。
这个句子里没有出现一般过去时态，所以没必要用had.

用had 的话须要加个时间从句来表示过去某一时间这样此句可理解为他在这个“过去某一时间之前”就已经历了生活中的起起伏伏用has 表明说话人在说此话时只是单纯地阐述他已经历了很多（言下之意就是他是个老手或历经磨难看破红尘等)
