Many people believe that yellowing and wetness are the greatest enemy of stamps. In fact, stamps are afraid of not only wetness, but also light and dirty things. People protect their stamps in several different ways.

 To protect stamps,we should never touch the stamps with our hands.This avoids moving dirty things onto them. Stamp tweezers (镊子) should be used in all conditions.

 Stamps are printed things. The colour will slowly disappear if the stamps are put in the light for a long time. So we should not put stamps in the light for long. Direct sunlight must be avoided as well.

 Wetness is an important  problem for stamps. Some  collectors  will put stamps  in separate plastic (塑料) bags. However, it is possible that some stamps have taken in some water from the air before they are put into the plastic bags.Stamps yellow easily and rapidly after they take in wet air.To protect the stamps, some people also put the stamps into a special room which has a machine to  keep the air cool and dry. However, not many people can afford that.

 To keep stamps, stamp collectors usually put them under plastic covers. It is a common and simple way. This helps because the plastic cover keeps the stamps off the wet air. It also stops the fingersfrom touching te stamps.

 Some  collectors  prefer  to  store  stamps  inside  a  plastic  box  with  desiccants  (干燥剂).However, we should take care not to let the stamps. touch the desiccants. On top of that, don't  take your stamps out on a wet day.

    When you sleep somewhere else, like at a summer camp or a friend's house, you know you're there for a fun time. But for some kids, when they are away from home they feel sad. They start to miss- their own beds, their own parents, and all the things at home. It's called being homesick (想家的). Do you want to feel less homesick? Here's how.

    Spend more time doing fun things. The more fun things you do, the less time you'll have to feel homesick. So try to take part in activities and soon you might start to have a good time.

    You can make a plan to call your mum or dad. For a one-night visit, maybe you can call once that night, and again in the morning. In the camp, you might set a regular day and time for a phone call home.  You can also send emails or short messages to keep in touch with family members and friends. If you're going to be away for a while, you might even write a letter! When you get in touch with someone, make sure to tell them about the fun things you're doing!

    Sometimes, just tell someone that you're feeling homesick. This will help you feel better. Maybe you can tell a friend that you feel homesick. And both of you can do something fun, such as telling jokes. If you're at a camp, a camp counselor (顾问) would be a good person to talk to. He or she might have some ideas to help you feel better.

    Now many people like to keep dogs as their pets. But how did dogs become humans' close friends?

    In some places of Europe (欧洲), about 10,000 years ago, some wild (野生的) dogs often came to human's houses to find food. The wild dogs looked different from the ones today. They looked like wolves (狼). At first, they felt ① frightened. They always stood and looked for a short time. Then they got the food and ran away. Sometimes the young dogs couldn't run fast and people caught them. People trained them and the young dogs grew up with the help of people. Slowly, the wild dogs became home dogs. They could make home safe when people were away. They helped people hunt (狩猎). They helped people keep warm on cold nights. ② Sometimes, they could smell and hear danger before people could. In some cold places, they helped people pull (拉) things people need.

    Now there are more than 400 different kinds of dogs in the world. And they look different from each other. The number and kind are growing all the time. Today, some people mainly (主要地) regard dogs as pets. In fact, dogs are really our close friends. We should protect them from being killed.

    Most Americans don't like to get advice from members of their family. When they need advice, they don't usually ask people they know. Instead, many Americans write letters to newspapers and magazines which give advice on many subjects, including family problems, the use of language, health, cooking, child care, clothes, how to buy a house or a car, and so on.

    Most newspapers regularly print letters from readers with problems. Along with the letter are answers written by people who are supposed to solve (解决) such problems. Some of these writers are doctors; others are lawyers(律师) or educations. But two of the most famous writer of advice are women without special training for this kind of work. One of them answers letters addressed to “Dear Abby”, the other is addressed(致函) as “Dear Ann Landers” experience their preparation for giving advice.

    There is one writer who has not lived long enough to have much experience. She is a girl named Angel Caveliere, who started writing advice for newspaper readers at the age of ten. Her advice to young readers, now appears regularly(正常的) in the Philadephia Bulletin in a column called DEAR ANGEL.

    Patrick doesn't like school. He thinks doing homework is too boring. He likes to play baseball and basketball after class.

    One day his cat is playing with a little elf (精灵). The elf says, "Help me! Don't give me back to that cat. If you help me, I can grant（承认you a wish." So Patrick says, "Help me do all my homework for 35 days."

    The elf doesn't always know what to do and he needs help. "Help me! Help me!" he says. And Patrick has to help. "I don't know this word," the elf asks. "Get me a dictionary. Look up the word." When it comes to math, the elf says," I know nothing about math. Here, sit down beside me and help me." The elf doesn't know anything about history, he says, "Go to the library. I need books. And you can help me read them, too."

    Patrick works hard every day. Patrick gets A at each subject. But I tell you a secret. In fact Patrick does the homework by himself.
