    Walking for a long time in a strong ,changeable light may cause some kinds of diseases. It {#blank#}4{#/blank#}  people feel terrible and is especially bad for the eyes. With less pollution, our planet will become {#blank#}5{#/blank#} and our health will be better.
Let's be greener people.

    Now more and more people get to know the importance of doing sports. It can {#blank#}1{#/blank#} fun to us and it's good for our health. {#blank#}2{#/blank#} what should we do?

    First, we should choose (选择) our favorite ones from different kinds of sports. The sports should be right for us. Second, we {#blank#}3{#/blank#} warm up (热身) before exercising. Third, as a beginner, you had better have an exercise plan. For example, how long are you going to exercise each time? How many {#blank#}4{#/blank#} a week? If you're a lover of sports, it's important to know this. Last, you had better not exercise if you fall {#blank#}5{#/blank#}, or it will be very dangerous.

    Life in the future will be {#blank#}1{#/blank#} from life today. Between then and now many changes will happen. But what will the changes be?

People will work fewer hours {#blank#}4{#/blank#} they do now and they will have more free time for sports，watching TV and traveling. Traveling will be much cheaper and {#blank#}5{#/blank#}. And many more people will go to other countries for {#blank#}6{#/blank#}.

    There will be changes in our food，too. More land will be used for building new towns and houses for all the people. Then there will be less room for cows and sheep，so {#blank#}7{#/blank#} will be more expensive. Maybe no one will eat it every day. Instead，they will eat more fruits and {#blank#}8{#/blank#}. Maybe people will be healthier. Work in the future will be different，too. {#blank#}9{#/blank#} will do dangerous and hard work. Because of this，many people will not have enough work to do. This will be a {#blank#}10{#/blank#}.
