Many cultures have different ideas about why people catch colds. For example in the United States, some people think that you can catch a cold if your feet get cold. So, mothers tell small children to wear warm boots in the winter. In other places, including parts of the Middle East, some people believe that strong winds cause colds. So, on trains and buses, people usually don't like to sit next to open windows. In parts of Europe, some people think that wearing wet clothes will give you a cold. They say that after you go swimming, you should quickly put on dry clothes. Today, scientists know that colds are caused by a virus（病毒）. But the old ideas are still very strong, and many people still follow them to avoid（避免）getting ill.

A funny thing happened to my sister Tina last month. She lives in Japan and teaches English. In Japan, people don't usually wear their outdoor shoes in the house or in school, and a lot of buildings have places for shoes. So her school has a special place for shoes. {#blank#}1{#/blank#}
Tina teaches English in the evening. One Friday, she went to school, and she put her shoes in the shoe box as usual. Then she had an interesting spoken English class with her students. {#blank#}2{#/blank#} But to her surprise, her shoes weren't in the box. There was only one pair of those there, and they weren't her shoes! She had to get home in a hurry. {#blank#}3{#/blank#}
On Monday, at her next English class, her shoes were in a shopping bag on her desk! There was a note that said, “I'm so sorry. I took your shoes by mistake!” {#blank#}4{#/blank#} Somebody felt a lot of shame!

                                                        Want to say "hello" from Disneyland? Send a post card!
   Beautiful scenes of paradise (乐园), wild animals, silly pictures — you can find them all in one place. Where? On a post card! Have people always sent post cards? No. Before post cards, people liked sealed letters.
   The idea for the first decorated (装饰) post card came to John P. Charlton in 1861. He thought a simple card with decorations would be a great way to send a note. Then in the late 1800s, post cards with pictures appeared. By law, people had to write their note on the front ——on the picture! The back was only for the address. Several years later, England allowed a divided-back post card. Then people could write their note on the back left side and put the address on the right. During the early 1900s, the golden age of post cards, picture post cards became a craze of the world. In 1908, Americans alone mailed over 677 million post cards. Today, post cards are the third most popular collection in the world after stamps and coins.

"I don't like my school, and I want to go home!" Do you have that idea that? A lot of children do. Now let's talk about it.

If you don't like your school, the first thing is to know why. You may not like your teachers. You may not have many friends at school. You may have problems with your subject s or homework

But what can you do with it? You can make some new friends. Going to school can be very interesting if you have many friends at school. You can make friends after school or when doing sports, then you can talk with them and do the same thing with them. You can also make school easy. If you don't like your teachers, you can talk with them. If you think your subjects are boring and difficult, you can ask others for help.

School is not a prison (监狱). You can learn to make your school life easy and interesting.
