he has been ill for 3 days 为什么不用sick

因为sick是短暂性动词,表示的是突发性的动作,例如：He got sick 3 days ago.而ill是持续性动词,可以表示一种状态的持续,一般会在后面跟上一个时间.还有记住,ill只能做表语,即放在be动词之后,不能做定语,例如,那个生病的男孩是我的弟弟,正确翻译为：The sick boy is my little brother,这里不能用ill.希望可以帮到你.
再问：俩个词好像都是形容词吧！！
再答：哦，是啊，我确实写错了。ill与sick是形容词，我无意中写错。
再问：形容词也分短暂性和延续性？
再答：当然啦，ill表示的是一种生病的状态，是持续性的状态，而sick是表示生病，并没有表示持续的意思，偏于表示一种突发的状态。同时，ill只作表语，不做定语。an ill boy是错误的，a sick boy 才对，而ill和sick都可以做表语。

he has been ill for 3 days 为什么不用sick she has been ill for 3 days,这里为什么要用been,直接she has ill 不行吗 It has been snowy for two days为什么不用snowing 这两个句子中的be动词是助动词吗?He has been ill for 3 days.you'll be ok. --You know mike has been ill for days.--yes,I wonder if he i She has been ill for over two days .(改为同义句） she has been ill He has been ___ （ill) for a week.答案是ill.been 后面不是要接done吗?为什么 he has been married for six years.为什么用has been married 而不用ha 求英文翻译啊 He has been sick for three It -- that he has been ill for a long time 为什么选择A呢 Aseems B 请问she sick for five days.空的地方应该是has already 还是has been her husband is ill,he has been ()for 7 years.
