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

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

some parents are think later school time will let their child have less time for study
1. 如果用are 后边要的think用ing表示持续动作.
我觉得用parents think就可以了.不用are.
2. later school time这个用法不对..later在这里用做...

some parents are think later school time will let their child have less time for study
1. 如果用are 后边要的think用ing表示持续动作.
我觉得用parents think就可以了.不用are.
2. later school time这个用法不对..later在这里用做形容词...而later的形容词意思是后来的；以后的.所以建议用retarded（延迟的）.
3.let 换成 make会更好.
4.for后边+动词的话要+ing.可以用for studying或者用to study.
eg:Some parents think the retarded school time will make their children have not enough time to study.
你那作文应该用现在时或者将来时.
因为那事情是现在或者以后会发生的..
i had done my homework.这个句子有点问题..
因为一般用过去完成时，都要有个句子代表那发生在过去的过去.
eg:i had done my homework before i went to school.
在我上学之前就把作业做完了.
如果要用一般完成时.
eg:i have had this car for 2 years.
i have had this car since 2008.
指的是从过去的某一时间开始到现在一直都拥有.
一般来说.用现在完成时都会有for 和 since 这2个时间词..
i have ALREADY done my homework.
i haven't done my homework YET.
是指知道现在我都做了/（还没做）。
already 和 yet这些也是标志着是现在完成时的时态的词语..
