【答案】Dear Tom，
   You say you want to lose weight but you are not sure how to do it correctly.I am writing to recommand some proper ways.
   First of all，I believe doing regular exercise is a good way to lose weight.You may choose to do some running，play basketball，or any sport you like.But sticking to it is the most important.In addition，going on a appropriate diet is also very helpful.You are supposed to have more fruits and vegetables and at the same time you'd better not eat any junk food，such as hamburgers and potato chips，which contain lots of fat and sugar.There is one more important thing to remember：avoid taking take weight-loss pills，which have side-effects and do harm to your health.
   I am sure you will feel better and look better in a few months if you keep regular exercise and go on a diet long enough.
   Best wishes.
Yours
