Mr Hu is an English teacher in China. He loves teaching very much. One day when he is giving an English lesson, he finds the headmaster(校长)sitting at the back of the classroom. After class, the headmaster tells him that he comes to his class to find out how much English and how much Chinese he is using. The result is about half English and half Chinese. The headmaster tells him that he should use more English in his class. Mr Hu makes a plan like this: Talk with an Englishman every Sunday for two hours to learn more English expressions(习语);Write some English expressions on cards; Have a five-minute talk in English with students before class; Speak more English in English classes.

    One year later, he finds he can use English freely.

    The "green" car has become popular in recent years. A green car is an environment friendly car. Today, most cars are powered (驱动) by petrol (汽油). They make our life easier. But cars have also made problems for the environment.

    There are a few new types of cars that use no petrol or a little petrol.

    Electric cars：This kind of car uses a battery (电池) for power. When you're not driving it, just plug it in like a mobile phone to power up the battery. They don't make exhaust (排放物). But car makers still can't make a battery that lasts for more than a few hours. That's why electric cars aren't very popular.

    Fuel cell cars (燃料电池车) : Fuel cell cars use hydrogen (氢) and oxygen (氧) to make power. The only exhaust they produce is clean water. But fuel cell cars are still much too expensive to make.

    Solar cars : This kind of car has large panels (板) on the top that take power from the sunshine. The car holds that power in a battery. Solar cars might be the cleanest of all. But no one uses them, because solar panels can't get enough power from the sun to make a car go for a long time. Also, they are very slow.

    Hybrid cars（油电混合车）： This kind of car is the most exciting kind, because it is very clean and not too expensive. The hybrid car is very smart: Half the time, it uses petrol, and half the time it uses a battery. So, when the petrol engine is working, it puts some of its power back into the battery. It uses much less petrol than other cars. It also makes less pollution for the environment.

    Andrew Carnegie was born in 1835 in Scotland. He was from a poor family. When he was twelve, his family moved to the USA. They wanted a better life. There, Andrew started to work right away. He got a job in a factory. He was a good worker, but he didn't like the job. Later, he changed his job. He worked at the Railroad Company where everybody liked him. He did many different jobs. His salary got higher every year.

    In his free time, Andrew loved to read. But in those days, the United States didn't have free public libraries. Luckily, he lived with a rich man with many books, who let young boys use his library for free, so Andrew could read as much as possible. He read throughout his life.

    Andrew learned a lot at the railroad company. He realized that the railroad was very important for big countries. He had a idea to start a business with railroads. He saved all his money and opened a business at the age of thirty years.

    First, his company made bridges for the railroads. Ten years later, it made steel for bridges, machines, and many other things. Soon he was the richest man in the world.

    Andrew liked to make money. But he believed it was very important to help other people. In 1901, he sold his company for $480 million. He started to give away his money to make new libraries and colleges all over the United States. He built 2811 libraries. Andrew also gave a lot of money to people who worked for peace. In 1903, he gave $1.5 million to build a Peace Palace in the Netherlands.

    Andrew Carnegie died in 1919.He was eighty-four years old. During his life, he gave away nearly all of his money. He gave away over $350 million for education and peace. There are colleges, libraries, hospitals, and parks named after Andrew Carnegie.He helped millions of people all over the world to study and learn.

    I had a summer camp with my classmates last year. Early in the morning, we gathered at the bus station. After saying goodbye to our parents, we got on the buses. It took us more than two hours to arrive at the camp ground.

{#blank#}2{#/blank#}

    We got off the buses cheerfully. Laughing and shouting, we jumped and ran all over the place. It was the first time for us to be away from the parents. Some of us started to feel homesick. However, when the night party and dances began, the homesickness（想家）was gone.

    The next day, everybody rushed to the boating class, hoping to be at the head of the others. At first, my friends and I worked hard, but the boat wouldn't listen to us and kept going round and round. Then the teacher taught us how to work together. After many tries, we did much better.

    Swimming class was my favorite. It was about the hottest time of a day and the best time to stay in the cool water. The swimming teacher was a funny man, and during the class he often made us laugh happily.

    During the week I learned a lot of new things and made many new friends. I also learned how to take care of myself.

Homework is a problem for students all over the world. As a student, you have a lot of homework to do every day.

    {#blank#}1{#/blank#}. And it helps you understand important knowledge.

    Luckily, there're several things you can do to make homework less difficult.

    {#blank#}2{#/blank#}. Write your homework down in your notebook if you need to. Don't be afraid to ask questions about it. Understand why you should do your homework.

    {#blank#}3{#/blank#}. Many schools have study halls. The students can study there. It's more interesting to play with your friends. But the more homework you finish at school, the less you'll have to do that night at home.

    {#blank#}4{#/blank#}.It is difficult to hold your attention for too long. So take some breaks while doing your homework. Taking a 15-minute break every hour is a good idea for most people.

    {#blank#}5{#/blank#}. If you don't finish your homework at school, think about how much you have left. It's a good idea to make a homework plan, especially when you want to enjoy sports or other activities.

    Many families make some house rules to make sure that everyone has a safe and happy home environment when they're home alone. Different families have different rules，but here are some rules many families follow：

    {#blank#}1{#/blank#}

    Keep your house keys hidden inside a pocket.

    Don't lend your keys to others.

    Hiding a key under a rock or a flowerpot isn't a good idea.

    {#blank#}2{#/blank#}

    Don't open the door to anyone except a sibling（兄弟姐妹）or parent.

    Keep all doors locked at all times.

    {#blank#}3{#/blank#}

    Most families have a rule that no friends are allowed in the house when someone's at home alone. This may be no fun but in the end，it is safer for everyone.

    {#blank#}4{#/blank#}

    Your parents may want you to stay at home and go nowhere-not even a friend's house，the park，or the store.

    {#blank#}5{#/blank#}

    Many parents ask their kids to wait until a parent is home before going online.

    These may sound pretty strict，but you'll be surprised how they help you feel safe！
