Dear dad and mom，

名师点睛

I would like to convey in this letter my heartfelt thanks to you.Without your support and encouragement，I wouldn’t have won the second prize in the National Mathematical Contest in Modeling.

First of all，you inspired me to participate in the contest and gave me the confidence that I could achieve a good result if I worked hard enough.In addition，you spent large sums of money on prestigious mathematical modeling teachers to help me with methods of mathematical modeling，thesis writing and computer programming，which laid a solid foundation for my outstanding performance in the contest.Finally，it is also worth mentioning that when I was downhearted in the face of difficulties and setbacks during the contest，it was you who raised me up to press forward.

All in all，your support in both spiritual and material terms made it possible for me to win a prize in the contest. So，thanks again for your kind help.I am looking forward to seeing you soon.

Your loving son，

Li Ming
