解答

1、with a knowlege of 是个固定搭配,掌握了,了解……的意思.they有特指的用法,the life是特指前面所提到的 a country's customs and culture
2、philippines和 tropical storms 是被动关系,所以用ed形式,又因为一个句子中只能有一个动词,前面已经出现了hit,所以后面不能再出现动词was
3、过去完成时had done指动作发生在过去的过去
现在完成时have been doing 指一个动作从过去开始一直延续到现在,甚至将来还有可能进行
一般过去时was\were\did一般看标志词,例如yesterday,this year等
