list 的过去式是什么 listed
write过去式wrote过去分词written Kitty has written a list. 为什么用written. 一般过去时用过去式，如：He wrote an email to his friend in Japan.现在完成时的结构：have/has+过去分词，如你的原句另被动语态也是用过去分词：be+过去分词，如：The classroom is cleaned by the students every day.
关于分词做状语的问题Worried about the time available，Zhang Pingyu had made a list of the sites she wanted to see in London .由于担心时间不够，张萍玉早就把她想在伦敦参观的地点列了一张单子.可不可以用worrying about.那个 有没有什么时候 过去分词做状语可以换成现在分词 （即互换）
