dear xxxx:
Nowadays,an increasing number of students come into senior three life.Now let me give you a short introduction of my last high school life.
At first,it is exciting and meaningful in short.Furthermore,it makes us realise time is limited.We always stay up late to finish those so much homework.Late term,we have a large number of examinations.We make an effort to relax ourselves.For example,searching internet and paly basketball.Last but not least,We believe that our future is very beautiful and wonderful.
That's all my senior three life.All of us will remember this unforgettable period of time.
yours xx
