In the years, I will be 24 years old. Our city will be a1living place then. There will be many tall buildings and trees. Many people will visit our2. Almost every family will have one or two solar(太阳能的)cars.

    People will3their cars to work every day. The libraries will have more computers, and people can 4books on them. The restaurants will have robot waiters to bring you 5. Schools will have more teachers from England to6you English. With the7of new transportation(交通方式), travel will be fast. You can only need two8to get to Africa! Machines and robots will do heavy and difficult jobs9we will have more time. What do you think? Do you think this idea about life10will come true?

    Researcher Robert Engelman from Population Action International says by the year 2025 about 3000 million people may lack water. At least 18 more countries are expected to have serious water problems. The need for water keeps increasing.

    Mr Engelman says the population in these countries that lack water is growing faster than in other parts of the world. The report says lack of water in the future may result in(导致)several problems. It may even increase1problems. Lack of water often means drinking water isn't safe. Mr Engelman says there are problems all over the world because of diseases, Lack of water may also2more international con flint(冲突), Countries may have to compete for water in the future. Some countries, such as Egypt, the Netherlands, Cambodia, now get sixty percent of their fresh water from other countries. And the report says lack of water would affect(影响)the ability of developing to improve their economies. This is3new industries(工业)offer need a large amount of water when they are beginning.

    The Population Action International study gives several solutions4the water problem. One way, it says, is to find ways to use water for more than one purpose.5way is to teach people to be careful and not to waste water. A third way is to use less water of agriculture, The6also says long-term(长期的)ways of dealing with the water problem must include controls on population growth.

    Some people say they have an answer to the problems of cars crowding and pollution. In many cities, hundreds of people ride bikes to work every day. In New York city, some bike riders have even1a group：Bike for a Better City. They say it more people rode bikes to work, there would be fewer cars and less dirty air.

    For several years this group had tried to get help for bike riders. They want to have special roads for bikes only, because when bike riders must use the same roads2cars, there may be an accident. Some people from Bike for a Better City feel if there were bike roads, more people would use bikes.

    But3bike roads have been ready yet.

    Not everyone thinks it is a good idea. Drivers don't like it, and some shop owners don't either. And most people live quite far from the city and have to travel by car. Still 4has been done about it. On Saturdays and Sundays, the largest open park in New York is5to cars and the roads may be used by bikes only, but the group still says this is not enough and goes on fighting6bike roads.

    When you're closing your eyes and hitting your pillow, you're probably not giving much thought about the sleeping position throughout the night. Most people don't change their sleeping positions throughout their lives. The following is why you might want to pay more attention: Your sleeping position can actually say a bit about who you are and what your personality is like.

    There are many sleeping positions. The fetal (胎儿的) sleeping position is generally the most common sleeping position. Fetal sleepers sleep on their side, they move into a position in which their body makes a rounded shape. People who sleep in the fetal position are often quite sensitive and generally shy. They are often worried or nervous and don't focus their attention on the main problem, but get into trouble on very small pieces of information.

    The log (木头) sleeper rests on the side with a straight body when hands and legs are kept at the sides. These sleepers are often relaxed, but also can easily believe lie-tellers. If you're a log sleeper, you might want to keep in mind that it's good to be easy-going and have less stress, but don't be so quick to go with the flow (流) at all times.

    The third one is the soldier position. Soldier sleepers typically lie on their backs with both arms close to their sides. In general, they are the strong and silent type. However, they can also put the pressure on. "They can be quite strict with themselves as well as others," a scientist added.

    It's hard to make friends if you stay at home all the time, so get out of the house and do things that will put you in touch with(接触)other people. It's easier to make friends with them when you find you like the same things as other people.

Don't be afraid to show people what you're really good at. You can talk about the things you like and do best. People will be interested in you if they, hear something interesting about you.

    Look at people in your eyes when you talk to them. That way, they'll find it easier to talk to you, or people may think you're not interested in them and may stop being interested in you.

    Be a good listener. Let people talk about themselves before talking about "me, me, me” You can ask people lots of questions and show that you are interested in their answers.

    Try to make friends with the kind of people you really like, respect(尊敬)and admire(羡慕). You shouldn't just make friends with those people you will meet them easily. Try to be friendly with all kinds of people. That way, you'll have a bigger group of people to choose from. Then you'll be easier to make friends with other people.
