十万火急！麻烦帮我写封英文信，本来要去City University 念心理学，因为膝盖受伤，想延迟一年。谢谢了！

I planned to study in Cith University majoring in psychology, but because of the current knee injury, I hope to apply for one year delay.

City University was originally meant to study psychology, because of a knee injury to one year delay

这都不会写？还去英国！
