【答案】Dear David，
        Last week，our school did a survey about "Who is your idol？".Here are our answers.In the past，we thought singers and movie stars were our idols.They always have cool hairs and clothes.They are fashionable.Also，they are talented and can put on funny shows.Their performances are so relaxing that they make our life colorful.But now we think scientists and medical workers are our idols.Scientists invent high-tech products to protect national security and improve people's living standard.Doctors and nurses save people's lives and help them get out of pain and back to health.When our country and people are in trouble，they help people with wisdom，courage and hard work.
       In my opinion，those who help us when we are in need deserve our respect and admiration.As students，we should learn from them and study hard to be a useful person to the country and society.
