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
答
这种作文,如果是讨论这样的经常发生的,不应该采用过去时态,而要用现在时态,你的例子也是现在时态的,而且错误太多了
Some parents think that later school hours will mean that their kids have less time studying at school.
我完成了作业.
I finished my homework.这个用过去时态是对的
你可以把你的大意写出来,大家可以帮你修改一下
