问题描述：
过去式与过去分词
今天要写一篇作文,关于同不同意迟点上学（英文）,那么那些动词是不是都要是过去式
这是我开头的句子some parents are think later school time will let their child have less school time.还有解释一下什么时候用have had has,had是have过去式,i had done my homework,是不是过去完成时?
开头句子搞错了，是some parents are think later school time will let their child have less time for study
