Дорогой друг, 
Любезно напоминаем, Вы всё ещё имеете неоплаченный заказ, китайская почта не будет работать в следующий понедельник, итак, любой неоплаченный заказ, не будет иметь времени, для того, чтобы быть отправленым раньше CNY*, надеемся на Ваше добродушное понимание и огромную
Сэнди.

Возможно и немного по иному:
"Вы всё ещё имеете неоплаченный заказ" - вы все еще имеете заказ, который не получил оплаты.

*CNY - простите, что это за аббревиатуры, я, к сожалению, не знаю.

Текст очень сложен для восприятия.

I think sport is very important in our live. It's popular both among young and old people. People go in for different kinds of sport They are: hockey, football, golf, cycling, basketball etc. Everybody may choose the sport he is interested in. There are PT lessons in every school. Students play basketball and volleyball at the lessons. Some people like to take part in sport competitions and others like to watch them. I think most people like watching more than participating. Many people say that sport takes a lot of time and energy. I think so too. That's why sport is for strong and purposefull people.To have good results in sport you need to train very hard.. Sport teaches people to win and to lose . Also sport keeps your mind healthy. I'd like to try to do figure skating and artistic gymnastics, for artistic gymnastics is my favourite sport.
