Dear Mrs. Malcolm,
亲爱的马尔科姆夫人，
I want to say how sorry I am about Chris.
对于克里斯的离去我感到很难过。
During the last year I worked with him continually and I am sure I could not have found anywhere another companion so brilliant and yet so charming and unconceited.
去年我一直和他共事，我确信，像他怎么优秀，迷人而又不自负的人今后我不会再遇到了。

I regarded my interest in my work, and in such things as astronomy (to which he introduced me) as something to be shared with him and I think he felt a little the same about me.
我很喜欢和他分享我的工作，还有他介绍我学习的东西，比如天文学。我想他也是这么认为的。
Although that interest is partly gone, I know I must put as much energy if not as much interest into my work as if he were alive, because that is what he would like me to do.
尽管我对工作兴趣已经不大了，但我知道我必须全身心的投入工作，就像他还在世一样，因为如果他还在的话，他会希望我这么做的。
I feel sure that you could not possibly have had a greater loss.
我知道这是你人生中最悲痛的事了 。
yours sincerely,
谨启，
Alan Turing
