Question

求解答 这个老人已经死了2年了。 The old man has( )( )for two years. ( )two years( )the old man died.

Answer 1

The old man has been dead for two years.
It‘s two years since the old man died.
这个句子涉及到了延续性动词和非延续性动词。
死亡是一个瞬间完成的动作，不能和表示时间段的时间状语连用，要用相应表示状态的词代替。
这里我们用词组be dead 表示这个人已经死亡的状态。
同类的词还有
buy (用have,keep代替)；marry(用be married代替)；leave(用be away from代替)
第二题就是一个固定句型：It's+时间段+since……或It has been +时间段+since……。意为自从某事发生到现在已经有多久了

Answer 2

the old man has been dead for two years. Since two years ago, the old man died.但是这样说有点奇怪，the old man died since two year ago 更舒服一点。

Answer 3

The old man has (been ) (dead )for two years.
(It's ) two years ( that) the old man died.

Answer 4

been away about ,,,ago

Answer 5

The old man has (been) (dead) for two years.
(It's) two year (since) the old man died.
