还记得“女英烈传”里的那首诗吗？

这个坛子里的人应当知道英国电影“女英烈传”(原名“Carve Her Name with Pride)吧？里面的那首诗还记得吗？
当年学英文，有幸通过熟人从外文书店的内参室搞到电影原版录音，听了无数遍，
把那首诗背了下来，写在一张漂亮的卡片上，作为定情物，给了他。
这许多年，一直想找它的出处和作者。今天在新闻的头版头条看到了。

A Poem by Leo Marks titled "The Life That I Have,"

The life that I have is all that I have
And the life that I have is yours
The love that I have of the life that I have
Is yours and yours and yours.
A sleep I shall have, a rest I shall have
Yet death will be but a pause
For the peace of my years in the long green grass
Will be yours and yours and yours.
