【答案】Dear Bill，
    How are you doing？I'm sorry that you couldn't travel during the summer vacation because of illness.Twenty five percent of the students in my class took part in the summer camp.Forty percent of the students met interesting people.I took part in the English singing competition and won the first prize.My summer life was rich and colorful.
    It is known to all that nowadays more and more people are concerned about their health.So it is of great importance for us to know how to keep healthy.First of all，it's necessary to keep a balanced diet.We should eat less junk food and eat more vegetables and fruits which contain lots of vitamins.Moreover keeping a good state of mood is also good for our health.We should always have an active attitude towards life.Last but not least，make sure we take regular exercise every day.Running or walking，simple as it is，has a positive effect on our health.
    Best wishes!

Yours，
Li Yue
