Today, I am very happy to have a meeting with you. At the meeting we will talk about the 1 we have these days. We all know the problems of 2 and the objects falling from windows are getting worse. We have received lots of letters about such problems. So   3 is time for possible ways to work out these problems.

    Some dog owners don't take care of their dogs well enough, and they let their dogs make mess on the roads and in gardens. This makes the environment 4. I would like to tell the dog owners that their behavior is too b ad, and at the same time they are making people 5 unhappy. We should keep the environment 6.

    It is reported that some people 7 rubbish out of the windows. It is dangerous because falling objects 8 hurt others. It is against the law. We should put up a notice to teach people not to do so. If it is found, we will record the names and address of those people who throw objects. Then, a warning will be given and 9 will be punished by law.

    A safe and comfortable living environment is important to us. 10 we try our best to care for our community, it will be a good place to live in. Thank you for your coming.

    Air pollution(污染) is a big problem. It's bad for all 1 things on Earth，and it is not the only one kind of 2.Water pollution makes fishand pollutes our drinking water. Noise pollution makes us get3more easily.

Many countries are making rules(规定) to fight against pollution. They try to stop people 4 burning coal(煤)in the city and releasing(排放) dirty smoke into the5.And if people use 6fewer cars，the air will get 7.

    8earth is our home. We must protect it and not destroy it. That is to say, we should keep the land, water and air 9.At the same time, we had better plant more trees10they can provide a lot of things for us and make our earth beautiful.

    There was a small village near the mountain. There were a lot of trees in the mountain. People in the 1always got something from the mountain, such as animals and trees. When they wanted to 2a house, they cut down the trees. And they also killed the animals for 3. Trees were very 4in their daily life. They made tables, chairs 5beds by cutting down the trees. In addition, when they 6meals, they still used some trees for wood. However, they only cut down trees but 7planted new trees. So the trees were fewer and fewer and the animals were becoming 8as well.

    One summer, it rained 9in the village. The rain lasted for about a week. The soil and the stones on the mountain fell down and soon 10the whole village. They finally realized they couldn't only cut down trees but also needed to protect them.

    Electricity is very useful in our daily lives. It is said to be one of the greatest1 in human history. It lights our world, 2 our homes, cooks our food and gives us lots of happiness. Electricity brings brightness. Today, almost everyone around the world uses electricity in one way or another. It is 3 to imagine our life without it. When the power is off, schools, offices, shops and factories cannot 4 at all. Without electricity, our5 would be very difficult. In large cities, electricity lights the streets and buildings. It warms people and 6. People can heat food in microwaves. Electricity also cools our food in7. Electricity drives underground trains, works traffic lights and lifts the machines in factories. Radios, televisions and computers use electricity to bring entertainment（娱乐）and news to millions of 8 every day. In the countryside, electricity also helps a lot. In villages and on farms, electrical machines milk the cows. They also cool the milk and keep it 9for us to drink. In fact, electricity is used as much in villages as it is used in 10.

    A great way to limit(限制) your impact(影响) on the planet is to follow other animals' way of eating. Squirrels（松鼠）, 1, eat nuts close to their tree houses. Elephants eat trees or plants that 2 around. What these animals are doing is eating in season and locally. We can do the same.

    Most of our favourite fruit and vegetables have their own natural seasons. Modern farming techniques make it 3 for us to eat all kinds of things any time of the year. However, 4 we eat our food in their natural seasons, we will save more energy.

    Eating locally means eating things that are grown close to your home. It will lower the impact that you and your eating 5 have on the environment. An easy way to 6 local produce is to shop at a nearby farmer's market.

    One of the best things you can do is to grow your own food. It may seem like a lot of 7but people and communities all over the country grow some or all of their own food.

    There are many 8 to grow your own food. By doing this, you can 9 where your food comes from. Besides, you can make sure that your food is fresher. It can 10 weeks for the food to get from the farm to the supermarket.

    By growing your own food, those weeks become just days, hours or even seconds. Now that's fresh!

    John comes from England. When he comes to China, his friends tell him something about the traffic 1 in China. People drive on the2 in England, but in China, people should drive on the right. Before you cross street, you must look 3 ways look left, look right and look left again. 4 remember the traffic moves on the right in China, or some cars and some buses may5 you.

    In the morning and the evening. when people go to work and 6 back from work, the streets are very busy(累忙的). 7  it is the most dangerous(危险的)time. When you want to 8 the road, you must 9 for the green "walk" sign.
