是What happened 还是what’s happened为什么不能有‘s呢?

是What happened 还是what’s happened there are many people there,___?a.what was happened b.wha happens c.what has happenedd.what happened what happened with you? 还是 what happened to you? 哪个是对的? 是What happened 还是what’s happened为什么不能有‘s呢? 是what has happened to还是what has happened at快,还有后面加什么! what's happened 中的“s”是has吗?还是is?还是was?还是什么?what's happened和what happened有区别吗?如果别人问what's happened应该怎么回答?问what happened又该怎么回答? What is happened?happened是形容词、名词还是动词?学语法乱了乱了 He asked,What has happened to you?变为间接引语该怎么变是He asked what had happened to me.还是He asked what I had happened . “发生什么了”翻译,到底是用What happened?还是What't happened?哪个是对的呢? 发生了什么事?用英语怎么说?是“what's happening?”还是“what happened?” what has happened是什么意思 是固定句子还是?为什么用HAS 英语翻译是 What happened was he on his way home yesterday?还是What happened was he on his way home yesterday?为什么..如果两个都不是 , what happen to you还是what happened to you? what happen to sb 还是 what happened to sb do you know what happened to them还是do you know what they happened为什么？ 发生什么事了?帮我翻译一下what has happened?what happened?请问第二种说法明明是疑问句.为什么要用happened呢?还是第二种表达是错误的? What happened to you?还是 for you还是 at you what引导的名词性从句随便写一句,i want to know what happened to him.what happened to him是主语从句,what作主语,可是如果像这种what will happen ,是疑问句?还是主语从句?what happened to him ,是疑问句还是还是主
