英语祈使句问题
Don't let your teacher worry about your studies.
1.这里为什么要用studies?复数?worry 又不用?
2.是不是除了一般现在时在改一般疑问时 把助动词提前 并且谓语动词变原型?其他事态 把助动词提前 然后谓语动词就保持原样?

1、首先,这句话的意思应该是：不要让你们的老师担心你们的学业.所以,study要用复数studies,不是单指一个人的学习.
Let sb.do sth.是固定搭配,worry要用到原形.
2、疑问句中谓语动词的时态,我们举例来说明下：
He goes home.→ Does he go home?
He went home.→ Did he go home?
He will go home.→ Will he go home?
He has gone home.→ Has he gone home?
He had gone home.→ Had he gone home?
He is going home.→ Is he going home?
He has been going home.→ Has he been going home?
疑问句中句子时态不能变.希望你能理解上面的例句.有问题可以继续问哦.

studies是名词，表学习。worry 前有let，所以要用原形。
2、把主语省，保留原动词就成了。
我是从事英语的，不明再问啦。
