This week, our topic is pollution. What are the answers to all of our pollution problems? We asked two experts to give their views.

    ◇Forest Smith is a member of Green First, an environmental group.

    Our future on the Earth looks very bad. We are dumping waste on our land. We can't breathe the fresh air. The sea is polluted too.

    I visited some relatives recently in a small village. They grow their own food and cycle everywhere. They are not wealthy, but they are happy and healthy.

    We must close the factories producing useless products. That will reduce rubbish and air pollution. We must recycle more, give up all cars, and improve public transport.

    A big problem is overpopulation in big cities. We must give up big cities and factories, and go back to a simple way of life.

    ◇John Green is a scientist at a university.

    Things are not as bad as Forest says. We'll have a bright future. We don't need to give up cars but we need to invent better, cleaner engines.

    This won't stop the problem of traffic jams. So we need better public transport. We should also recycle more.

    But some things are getting better. My sister returned last month after living abroad for five years. She said, “Our old neighbourhood doesn't look the same as before－it is cleaner and greener now.”

    In a word, science has brought many improvements to our life.

    Exercising is a good way to keep fit. However, many people do not know how to exercise well. Here are some tips.

    First, you should warm up. It is important to warm up before you exercise. You need to stretch your legs, arms, back and neck before you do any difficult activities like running.

    Second, you should find good places to exercise. You do not need to spend a lot of money. You can run or do sports in a park or in your school gym. You don't need to buy exercise equipment for your home. Just get your body moving. 

    Third, don't work too hard. Choose a sport that you enjoy and then your exercise will be fun instead of work. Also, you only need to exercise a few times each week. If you exercise 30 minutes each time, you will stay healthy.

    Fourth, drink enough water. It is important to drink water when you exercise. Your body needs the water for energy and for keeping cool.

    Finally, you must be careful! If you hurt yourself while you are exercising, rest until you feel better. Exercising when you are hurt is bad for your health.

    A life coach is somebody who helps you reach all kinds of personal and professional goals(目标). Each of us has the ability to be our own life coach. Here is some advice about how to be your own life coach:

    Pay attention to your relationships with others. Ask yourself the following questions: How do you deal with disagreements? When was the last time you showed your family members that you care for them? Your relationships with friends, family members and teachers show a lot about the kind of person you are.

    Face the fears about the future. Now, imagine that one of your good friends told you that he or she was not strong enough to go back to school. We often give better advice than we are willing to take ourselves. Remember that even the most successful people were probably told that what they wanted to do was impossible. ①但是他们坚持努力工作，永不放弃。

    Develop your talents. ②If you want to achieve your goals, you will have to spend more time developing the talents you already have. And you should also uncover (发现)any hidden talents that you haven't discovered yet. So you can take classes in subjects that you are interested in, even if you have no experience.

    Be thankful. Take some time to be thankful for the things you do have. Remember positive (积极的) things. Think of the best days you have had in the past month or year. Remember special parties, vacations and holidays. Thank for the wonderful people you have in your life.

Ladies and gentlemen,

{#blank#}1{#/blank#}Good morning. I am proud to introduce our “Oriental Moscow” Heilongjiang.

{#blank#}2{#/blank#}First, I want to introduce the geographical location, size of Heilongjiang province. Heilongjiang is the northeast of the country, covers an area of 46 square kilometers, the west is plain(平原) , the northeast for Sanjiang plain, North and southeast for mountain.

{#blank#}3{#/blank#}Long and cold in winter, summer is short and cool, large temperature gap between north and south, so north even have no long winter and no summer. So in summer we can have holiday, in winter we can watch the snow view and lantern Festival(冰灯) .

{#blank#}4{#/blank#}Next to introduce the Heilongjiang's features: First, due to the volcanic(火山的) remains a lot, volcanic activities for Heilongjiang created the tourism resources for Heilongjiang. Second, local literature and art in Heilong —- ice sculpture(冰雕) . Since the 60s, ice sculpture has so far been has wide influence. It has over 200 years history of Er'renzhuan.

It displays the Harbin scenery as a unique architecture. It is welcoming every visitors by using the unique charm and rich content. The central street – Harbin is affected by European culture, reflected in too many European architecture.

    Now let my partner to introduce the other beauty of Heilongjiang. Thank you.

    Have you ever counted the number of digits (数字) in your mobile phone number? Your number has 11 digits. You may sometimes find it hard to remember your number. That's because China has the longest mobile phone numbers in the world. Why is that?

    The 11 digits can be divided into three parts. Each part has a different meaning. The first three numbers tell you which mobile phone service provider (提供者) you are using For example, 135 is for China Mobile Communications Corporation and 188 is for China Unicom. The fourth to the seventh digits tell you where the number is registered (注册). And the last four digits are random (随机的).

    The main reason for using 11 digits is that we have the largest population in the world. We once had 10 numbers. But as our population grew, there were not enough numbers for us to use. So we began to use 11 digits starting from 1999. Eleven digits can be used to make tens of billions of mobile phone numbers. That's enough for each person to have seven or eight phone numbers to use in China.

    And mobile phone numbers can be recycled. Usually, the service provider will reuse a canceled number after three to six months. If you call a number that you haven't contacted (联系) for a long time, you may find that its owner has changed.

    Besides China, Britain and Japan also use 11-digit mobile phone numbers. But their numbers always start with 0. So they cannot create as many numbers as we can. Countries like the United States, Australia and India use phone numbers with 10 digits. Canada's mobile phone numbers are perhaps the shortest in the world: they use seven digits.

    Do you often think of life in the future？Will we study at home？Will we have robots？Will we fly to the moon easily？Everyone may have his or her views about that. Life in the future will be very different from life today. Between then and now many changes will take place, but what will the changes be?

    There will be changes in our food. Maybe no one will eat meat. Instead, people will eat more fruit and vegetables. People will stay away from junk food. Maybe people will be healthier.

    Computers will be small and useful. Maybe we will even put the computer into our pockets(口袋). There will be at least two computers in every home. And computer studies will be one of the most important subjects at school.

    Work in the future will be different, too. Dangerous and hard work can be done by robots. People will work fewer hours than they do now. And they will have more free time for sports, watching TV and traveling.

Life in the future
