Dear Mary
I've received your e-mail.Don't worried about me.I'm getting on well with my research work in the lab.But in my surprise,you say you will give up learn English.The reason is because you have not done well in it recently and you have lose interest.I'm afraid I can't agree with you.I know it is not easy to learn English,and it is widely used in the world today and it will be important tool in the future.Beside, it is becoming more and more important in our daily life.I am sure that if you study hardly,you will succeed.I'm looking forward to hearing a good news from you!
Yours,
