【正确答案】范文 As is symbolically illustrated in the cartoon, wearing a white gown and a stethoscope, a doctor is holding a medical record and speaking to his patient in a ward of a hospital. Apparently, the intended meaning of the drawing is that people are doing less and less exercises now, which is not a piece of good news for their health. There are numerous ways of keeping fit. First and foremost, it is most effective to do physical exercises. We can choose jogging, playing basketball, swimming, skating, climbing or riding as regular exercises, because exercises never fail to make us stronger and more energetic. Moreover, we should put great emphasis on forming good habits. A balanced diet and sufficient sleep are both indispensable to physical fitness. Finally, mental health should also be taken seriously. Especially in adversity, we need to maintain an optimistic mentality to pull through life's pain and sorrow, twists and turns. To sum up, all these practices guarantee a fit health and a happy life.
