Some people think that they have an answer to the problems of automobile crowding and pollution in large cities. Their answer is the bicycle, or bike.

In a great many cities, hundreds of people ride bicycles to work every day. In New York City, some bike riders have even formed a group called “Bike for a Better City”. They claim that if more people rode bicycles to work there would be fewer automobiles in the downtown section of the city and therefore less dirty air from car engines.

For several years this group has been trying to get city government to help bicycle riders. For example, they want the city to paint special lanes—for bicycles only—on some of the main streets, because when bicycle riders must use the same lanes as cars, there may be accidents. “Bike for a Better City” feels that if there were special lanes, more people would use bikes.

    But no bicycle lanes have been painted yet. Not everyone thinks it is a good idea. Taxi drivers don't like the idea—they say it will slow traffic. Some store owners on the main streets don't like the idea—they say that if there is less traffic, they will have less business. And most people live too far from downtown to travel by bike.

The city government has not yet decided what to do. It wants to keep everyone happy. On weekends, Central Park—the largest open place in New York—is closed to cars, and the roads may be used by bicycles only. But “Bike for a Better City” says that this is not enough and keeps fighting to get bicycle lanes downtown. Until that happens, the safest place to bicycle may be in the park.

    Kingfishers (琴鸟) are small beautiful birds. They have blue bodies, and look 1 cute. Fish is 2 favorite food. They don't live 3 the trees. They live in holes (洞) in the riverbank. But kingfishers are in great 4 now. People change (改变) many rivers. The rivers have new riverbanks, 5 kingfishers are losing their 6. People also make many rivers very 7, so there 8 no fish in the river. There isn't 9 food for kingfishers. We must 10 kingfishers.

    Nowadays, WeChat is becoming more and more popular in China. No matter where we are, we can sign up and send text or voice messages to our friends. We can also find a stranger to talk to by shaking the 1^. Another funny function is that WeChat can help to search for people  2 live nearby with the programme on. Many people like this function, 3 it can help them to find more people who they may know.

    In my opinion, WeChat is really4 useful chatting tool. It can help people 5 with their friends more easily.6 , it is also bad for people, especially for students .As you see, some people use WeChat 7 too long. It is not healthy to them .So I have some 8 on how to use it in a correct way. First, we should not use it when we are studying. We can't focus on our study if we use it. Second, we must be careful. We should neither show too much personal information9 trust strangers so much.

    We should learn how to use it properly. Remember, WeChat is not everything in your life.10depend too much on it.

    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.

    Saving the environment is actually quite simple, when you come to think about it. It does not have to be a problem. If you and everyone follow these tips, you are helping save the environment easily.

    Switch off the lights when you leave the room. By now you have probably wasted thousands of watts (瓦特) lightening your room 1 you weren't there. If you work on a home office, this habit is not only bad for the environment, but also for your pocket.

    Turn off the computer when possible. If you know that you will be 2 for four hours or more, turning it off could lead to large savings over the long run.

    Print only when necessary. Sure, reading on paper might be more comfortable, but you should avoid printing those two-line e-mails every time. Read it on the screen and print only necessary documents. Remember also to use 3 sides of the sheet.

    Use fluorescent lamps (荧光灯). The fluorescent lamps may 4 more in the stores, but within the time you use one, you should have already recovered the investment. A normal incandescent light bulb (白炽灯泡) lasts 750 hours but a fluorescent bulb will give off the same amount of light yet last for 7,500 to 10, 000 hours with 1/3 of the wattage.

    Use low-flush (冲洗) toilets. In your household, 40% of the pure water is flushed down the toilet. You can 5 this easy way at home; use small plastic bottles, filled with water or stones to displace (置换) the amount of water in toilets. This will make it a "low-flush toilet", or you can use a displacement bag in your tank, which might reduce 1-2 gallons per flush.
