Different people have different hobbies. Some like growing flowers, some like singing and others like building model ships. I'm interested in stamps and started to collect them in 2008.

    My father works in a big company. He always goes abroad. Eight years ago, when he was working in America, he sent home a letter with a beautiful stamp on the envelope(信封). I liked the stamp very much. From then on I have always asked my father to send me different stamps from different countries. Later I joined a club and I have made many friends there. They helped me learn more about stamps and always traded(交换) stamps with me. And I got some special stamps from them.

    Now I have more than a thousand stamps. When I look through these beautiful stamps, I feel relaxed and happy. I can enjoy the beautiful designs of stamps.

    I have a cold. I feel very tired. My throat is sore, I have a cough and my head hurts. Last night, {#blank#}1{#/blank#}. The fever made my body feel hot. I really don't like being sick, because I can't go to school. And my friends can't visit me, either. {#blank#}2{#/blank#}.

    There is no cure（治疗）for the common cold. Below are three ways to help stop a cold spreading and to feel better again.

    First, wash your hands. Washing your hands is the most important way to stop the spread of colds. Cold germs(细菌）are spread by touch. {#blank#}3{#/blank#}. So if we wash hands carefully using soap and hot water. We won't get the cold easily.

{#blank#}4{#/blank#} There is a saying that "coughs and sneezes spread illness". Always use a handkerchief(手帕) or napkin to cover your mouth when coughing and your nose when sneezing. That way, the germs won't get onto your hands and spread to things you touch such as doors, cups or plates.

    Finally, clean your house and take care of yourself. We can use a robot cleaner to clean our house on time. Be sure to use only your own toothbrush and cup……

    {#blank#}5{#/blank#}, but if you get worse, you should see a doctor at once. Eat healthy simple foods such as soup or rice. Get enough rest and sleep. Stay in bed, read a book, do your schoolwork or practice your English!

    Remember that a common cold only lasts a few days. You'll feel better soon.

A. Next, cover your nose and mouth

B. The germs(细菌) get on to your hands and from there into your eyes, nose and mouth

C. We should stay away from all kinds of colds

D. I also had a fever so I didn't sleep very well

E. Because if one of you gets a cold, often all of you get it

F. Some cold medicines can help stop fever and aches

The name of the toy is "Goldie Blox". To interest girls, Sterling create the character"（Goldie". {#blank#}3{#/blank#} . Goldie tells stories, solves difficult problems and builds new worlds.

    Mia is a seven-year-old girl who likes science. In her room, she has no fashion dolls. Instead, she received a set of（Goldie Blox from her grandmother. {#blank#}4{#/blank#} Experts say parents should do more than just buy toys to interest their girls in STEM subjects. {#blank#}5{#/blank#}.

They took a lot of photos on the way and then they had a picnic under a big tree. ①Suddenly it began to rain heavily. So they hurried to the hotel. When they got there, they couldn't find their expensive camera. They wanted to go back to look for it, but there wasn't enough time because they had to catch the plane at 20: 30 that night! They didn't have dinner in the hotel because they all felt sorry. To make his family happy. Mr. Green said. "Well. ②让我给你们讲一个有趣的故事吧。 An old man lived in a 200-meter-tall building. One day he fell down from it by accident, but he didn't hurt himself at all."

    "It was a miracle(奇迹)" shouted his children, why?"

    "Because he lived on the first floor!"

    They all began to laugh loudly. Just at that time a policeman with a camera came in. He said a Chinese boy found it under a big tree and the boy asked him to find out the owner.

    "It's really a miracle!" the Greens said happily.
