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 your body needs.
Second, drink water and milk as often as possible. When you're really thirsty, cold water is the No. 1 choice. Milk is a great drink that can give you more calcium (钙) your body needs to have strong bones (骨头).
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 won't make you feel comfortable but will make you fat.
Fourth, limit (限制) screen time. Screen time is the time you watch TV, DVDs and videos, or use 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.

In so many ways, cyberspace (网络空间) reflects (反映) the real world. People ask for information, play games, and share hobby tips. Others buy and sell products. Still others look for friendship, or even love.
Unlike the real world, however, your knowledge about a person is limited (限制) to words on a computer screen. Age, identity (身份) and appearance (外表) mean very little in cyberspace. However, a person’s thoughts are what really matter. So even the shyest person can become a chat-room star.
Usually, this “faceless” communication doesn’t create problems. Identity doesn’t really matter when you’re in a chat room discussing your ideas or hobbies. In fact, this stress (压力) on the ideas makes the Internet a great place for exciting conversations. Where else can so many people come together to chat?
But some Internet users want more than just someone to chat with. They’re looking for serious relationships. Is cyberspace a good place to find true friends? That answer depends on whom you ask. Some of these relationships actually succeed. Others fail.
Supporters say that the Internet allows people to get to know each other intellectually (智力地) first. Personal appearance doesn’t get in the way. But others think that no one can truly know another person in cyberspace. Why? Because the Internet gives users a lot of control over how others think of them. Internet users can carefully change their words to fit whatever image (形象) they want to give. In a sense, they’re not really themselves.
All of this may be fine if the relationship stays in cyberspace. But not knowing a person is a big problem in a relationship. With so many unknowns, it’s easy to let people’s imagination “fill in the blanks (空白).” This unavoidably (不可避免地) leads to disappointment (失望) when people meet in person. How someone imagines an online friend is often quite different from the real person.
So, before looking for friends in cyberspace, remember the advice of Clifford Stoll: “Life in the real world is far richer than anything you’ll find on a computer screen.”

Cats have a pair of vomeronasal organs(犁鼻器) on the roof of the mouth. When the cat wants to sniff, she will breathe the air in through her mouth. At this moment, she will often squint(斜视) her eyes and maybe even flatten(使…平坦) her ears. This makes her look like she is making faces. The vomeronasal organs will then analyze(分析)the smell---almost as if the cat is tasting the smell.
When you come home from outside the house, your cat can smell what you had for lunch and for a mid-afternoon snack. She can smell the people you shook hands with and your neighbour you stopped to talk to and hug. She can smell the grass brought under your shoes as you took a shortcut across the lawn. Your cat’s sense of smell is so good that she can smell difference between a gallon of water with a teaspoon of salt in it and plain water. In comparison, we think of salt as completely tasteless.
Cats have scent glands(臭腺) on each side of the forehead, on the chin, the lips and next to the tail. When your cat rubs up against your hand, your leg, the sofa, and your bed, she is leaving her scent in those things. She will then use her sense of smell to recognize “her” things, people and even other pets in the home.
If you want to have fun with your cat’s sense of smell, take some small bits of different things, such as a bit of chicken, some flowers and some fish. Place each different scent under a piece of paper towel(so your cat cannot see any of them) and encourage your cat to investigate and find what kind of food she likes to eat best.
