30、Hi, dear boys and girls! Do you know how to be a healthy kid? Here are some rules you should follow.
First, eat different foods, especially fruit and vegetables. You may have a favourite food, but you'd better eat something different, if you eat different foods, you will probably get more nutrients (营养物质) your body needs.
Second, drink water and milk as often as possible. When you're really thirsty, cold water is the No. l choice. Milk is a great drink that can give you more calcium (钙) your body needs to grow strong bones.
Third, listen to your body. How do you feel when you are full? When you are eating, notice how your body feels and when your stomach feels comfortably full. Eating too much will not make you feel comfortable and make you fat.
Fourth, limit screen time. Screen time is the time you watch TV, DVDs and videos, or using computers. It is good to take more exercise such as basketball, bike riding and swimming. You can't watch TV for more than two hours a day.
Fifth, be active. One thing you'd like to do as a kid is to find out which activity you like best. Find ways to be active every day.
Follow these rules and you can be a healthy kid.统考英语阅读理解 The elephant is _ _ _ _ _ _ largest animal on the land. 大学英语（2） 8.学生的认知方式的差异有哪些？教育心理学 保护装置采用VFC为微机保护带来的优点描述准确的是（ ）。A、 稳定，线性好，精度高，电路十分简单B、 抗干扰能力强（电联系、磁联系频繁）C、同 CPU接口简单，VFC的工作可不需CPU控制 D、 很方便地实现多CPU共享一套VFC变换E、 保护装置采用VFC型的A/D变换，建立了一种新的变换方式电力系统继电保护 发包人擅自使用未经验收的建设工程，发现质量问题的，应当（ ) 合同法原理与实务 学校工作的中心环节是（）。(A) 教学 (B) 管理 (C) 课外活动 (D) 后勤活动小学教育学
