Nick is a 14-year-old school boy. His life is full of exams and studies on weekdays. He has little free time. He thinks playing computer games is the best way to make him relax. When he has free time, he sits in front of the computer. Just like that way, he neither eats nor drinks for several hours.

    Last weekend, he played games on the computer again. He was too excited and didn't want to move. He didn't have anything for six hours. When he had to go the bathroom, he found he could not move. He was taken to the hospital. The doctor told him he should do some different kinds of activities.

    After coming back from the hospital, Nick follows the doctor's advice. He often plays soccer with his friends. Sometimes he still plays computer games on weekends, but he never does it for long. Now, he lives a happy and healthy life.

Dear Miss Zhao,

    Thank you for introducing the summer camp program to me. This program is organized by Yueyang Education and Sports Bureau (岳阳市教体局). It has brought over 500 middle school students to the countryside to experience the life here.

    We have been in this small village for six days. Every morning we get up early, breathe the fresh air and hear the birds sing in the woods. 我们一走出房子，就可以看到花、草、树木和动物。 We go for walks through the countryside and watch the villagers do their daily activities.

    Li Guoqing, a sixty-year-old villager says, "Thanks to the government, great changes have taken place in the countryside. People mustn't cut down trees or build houses on the farmland (农田). Anyone is not allowed to make our rivers or lakes dirty. All villagers are supposed to put rubbish in the bin."

    We really enjoy the trip and come to realize the importance of protecting the environment. 每个人都应该参与保护环境。 If the environment is taken good care of, we'll have a cleaner and greener world. The clean water and green mountains are our treasures.

Yours truly,

He Wei

    China and Westen countries may have different ideas about certain animals, but when it comes to pigs, we have somehow reached an agreement﹣that pigs are ugly, lazy, stupid and shameless.

    But the truth is that pigs do have some finer qualities(品质). Science long ago proved that pigs aren′t stupid at all. A research shows pigs are" mentally and socially similar to dogs". They like to play. They have good long﹣term memories. And they know the difference between those who treat them well and those who don't.

    There are lovable pig characters in cartoons too. Peppa Pig(小猪佩奇), for example, a UK television series (连续剧)that began in 2004, has now become one of the most popular cartoons in 180 countries and regions. The four members in the cartoons pig family teach children from all around the world about love, friendship, and the value of family, And in China, McDull, a young pig who works hard toward his dreams even though he keeps failing, have been a popular cartoon character since 2001.

    Perhaps these are the qualities of pigs to keep in mind﹣intelligence, cuteness and patience.

    One day, you open the fridge and find some moldy(发霉的) food. But before you can throw it away, your mother stops you. She doesn't want to waste food. She cuts off the moldy pan and eats the rest. Is it safe to do this?

    Mold(霉菌) can grow on almost all kinds of food. Mold is usually green, white, black or gray.

    Mold makes food ®oft and changes it's color. Moldy food tastes quite bad—and it's not safe to eat.

    If you find mold in soft food, just throw it away. Bread, tomatoes and hot dogs are soft food. This kind of food allows mold to easily grow below its surface.

    But it's easy to remove mold from hard food. The mold can't grow very deeply inside this kind of food. According to the BBC, you should cut about 2.5 cm around and below the mold and remove it.

    It's OK to cut the moldy parts out of hard food and eat the rest. But if the food is completely covered with mold, you should still throw it away.

    Most kinds of mold are bad for us. But some kinds of mold can be used to make food. For example, peniciliium(青霉菌) can be used to make many types of cheeses, such as blue cheese. These cheeses are safe to eat and they're quite delicious as well:
