为什么是he has been dead for 10 years而不是he has dead for 10 years?为什么I have studied English for 10 years是对的?
为什么是he has been dead for 10 years而不是he has dead for 10 years?
为什么I have studied English for 10 years是对的?

为什么是he has been dead for 10 years而不是he has dead for 10 years?为什么I have studied English for 10 years是对的?
i have studied english for 10 years.这里的study是动词.而上句中,dead是形容词.
he has dead for 10 years?这句是现在完成时,现在完成时的格式是have/has + 动词过去分词,但是dead是形容词哦~
当然你会想如果改成he has died for 10 years?这里die是动词了总可以了吧.但是答案是不可以.die是一个瞬间动词,不可能死了又死的,还死了10年,对不?又如：i have kept the book for 3 days.keep在这里就代替了borrow,因为borrow是瞬间动词,你可以想象下借书这个动作持续3天会是多么搞笑.
还比如：用be这个延续性动词代替go这个瞬间动词：他去上海已经有10天了.he has gone to shanghai for 10 days.是不可以的,应该改为：He has been to shanghai for 10 days.
所以说,现在完成时中,表示持续一段时间的,要用延续性动词,不可以用瞬间动词.这个只能靠平时积累了.

dead形容词
study是持续性动词

同ls两位。。一个人可以不断的学习十年。但是不能不断的死十年。。比棒子剧还夸张了～

国为study是个可延续性动词，就是你可以一直保持学习这个动做十年，但是死是个非延续性动词，死这个动做一下就结束了，所以它没有完成时。

这是过去完成式与一般过去式的不同。他十年前就去世了，过去完成的动作

1，HE 第三人称单数 所以把have改成has
2，he has been dead for 10 years 这里has been 是现在完成时态，表示死了十年
3，he has dead for 10 years 这句改成He died 10 years ago. 或者He was dead 10 years ago.就对了

因为dead是形容词啊，前面需要一个动词，做句子的谓语；
studied就是句子的谓语；

为什么是has been dead不是has dead 为什么是he has been dead for 10 years而不是he has dead for 10 years?为什么I have studied English for 10 years是对的? Her grandmother has been dead for two years 为什么是Her grandmother has been dead for two years 为什么是用dead形容词,而不是died 不是现在完成时吗? He has dead.这种表达对么?与He has been dead的区别是什么? He 【has been dead】谓语【 for 3 years】状语 The fact that he has been dead is clear. he has been dead for a day 是什么时态的? 他死了英语怎么说?he has been dead 还是he is dead He's dead 和he has been dead的关系..he has been dead是现在完成时.没有语病..那为什么说he's dead也可以?..是不是那个been可以省去?还有he's是不是等于he has.. he has been dead for two year dead 有几种形式?用于什么时态? 为什么是How long has he been there 而不是How long has he gone there 他死了,用英语怎么说?1、He has dead 2、He has been dead 3、He is dead 哪个对?为什么对?其他的错在哪里? now he has ()there for two weeks.填been还是gone?为什么是been My grandfather has been dead for many years.这句话为什么用has been的形式 死亡为什么是被动语态?还有My brother has never been abroad before.这句话为什么也用被动语态? He has been to Beijing for 3 times He has died already He has been dead for 3 years 三句都对吗 He has been （ ） for several years括号中填died 还是dead He has been dead for three years这句话包含了哪些时态 用SICE或FOR填空,1,HIS FATHER HAS BEEN DEAD ----------HE WAS TEN YEARS.
