Grammar
The Present Perfect Passive Voice
现在完成时的被动语态
Dear Jack,
Long time no see! How are you these years?
I hear that Xi’an has changed a lot these years
and is now becoming an international city. As
you know, I went to Xi’an ten years ago. How
time flies! I still remember its beauty and the kind
citizens there. I have a good impression on Xi’an,
but it’s a pity that I have no time to visit it for
myself at present. Could you please tell me some
great changes in Xi’an in the past few years?
Looking forward to your early reply.
Yours,
Peter
