他已经死了五年了：He has been dead for 5 years.has done是现在完成时,为什么有个 b 为什么是he has been dead for 10 years而不是he has dead for 10 years He has been dead for three years Her grandmother has been dead for two years 为什么是 He 【has been dead】谓语【 for 3 years】状语 He has died for three years.He has been dead for three years she has been dead for three years.解释下been的作用.我知道是现在完成时,但不明白为 It has been 3 years since he smoked.为什么这句话的意思是他不吸烟已经三年了? 英语翻译已经知道的三种是1.He has been in the army for 5 years.2.He has b 他死了英语怎么说?he has been dead 还是he is dead jack has been dead for three years She___ for more than 2 years.A.has been died B.has been dead
