Dear Mary,
     I receive your E-mail just now. Don't worry about me. I'm getting on well my research
work in the lab. But to my great surprise you say you will give up learning English. The
reason is because you have not done well in it recently and you have lost interests. I'm
afraid I can't agree on you. I know it is difficult to learn English, but English
is wide used in the world today. It will be important tool in our future work. Beside,
it is becoming more and more important in your daily life. If you study hard, you will
succeed. Do remember where there is a will there is a way. I'm looking forward to
hear good news from you.
