A 拓展思考（示例） Part 1 You eat too much chocolate and cake. You shouldn’t eat sweets every day because they have lots of sugar. You should eat more fruit and vegetables. They help your body stay fit. You should also drink milk to make your teeth strong. Try to eat an apple instead of a chocolate bar. Part 2 Breakfast: a bowl of oatmeal with milk (bread group + milk group). Lunch: grilled chicken with brown rice and broccoli (meat group + bread group + vegetables). Dinner: fish with steamed carrots and a small potato (fish group + vegetables + bread group). Snack: a banana (fruit group). This meal plan is balanced because it includes all food groups and avoids too much oil or sugar. Part 3 I usually eat rice or noodles for lunch because they give me energy. I always have some vegetables, like tomatoes or carrots. I sometimes eat fish or eggs, but I don’t eat meat every day. I never drink cola because it has too much sugar. I think my diet is healthy, but I should eat more fruit. I should also eat less cake on weekends. 1 学科网（北京）股份有限公司 $
