Save Our Environment

    There is no doubt that global warming has become one of the biggest problems we face today. So it's important for us to protect our environment.

    As middle school students, what can we do? First of all, try to take bicycles and public transportation to school instead of cars b{#blank#}1{#/blank#} it will make less CO2( 二氧化碳) . It can not only be good for our health, but also make it possible for us to get closer t{#blank#}2{#/blank#} nature.  Then, it's necessary to p{#blank#}3{#/blank#} up rubbish and put it into dustbin( 垃圾桶) . Planting more trees can also help a lot. However, we should never forget to turn off the lights when we leave the class- room. B{#blank#}4{#/blank#}, why not reuse water and paper to live a low-carbon life?

    I think it's everyone's duty to help our Earth. And even the simplest activities can make a real d{#blank#}5{#/blank#} to our environment. So don't put it off! Let's do what we can to protect our home. I believe we will make our world more and more beautiful.

Dear Dr. Knowledgeable,

    I'm a {#blank#}1{#/blank#} (help) mother. My son Tom is 15 years old. I find that the {#blank#}2{#/blank#}(old) he grows, the less we talk. I feel very sad and I really need your help. My first problem is {#blank#}3{#/blank#}his hobbies. He spends almost all his spare time {#blank#}4{#/blank#}(play) computer games. When he gets home, he always turns {#blank#}5{#/blank#} the computer and closes the door.  I'm getting worried about him, {#blank#}6{#/blank#}(especial) when his English teacher tells me he always gets low marks in the English exams. Second, he likes new technology, but I can't afford all the things he {#blank#}7{#/blank#} (want). Recently, I've found that he is always alone. I've never seen him talking to his friends on the phone {#blank#}8{#/blank#}going out with other kids at weekends. What should I do {#blank#}9{#/blank#}(help) him? Please give me some {#blank#}10{#/blank#} (suggest).

A mother

    Every morning Tom {#blank#}1{#/blank#} (go) to work {#blank#}2{#/blank#} train. He has a long way to go. So he always buys {#blank#}3{#/blank#} piece of newspaper. It helps him {#blank#}4{#/blank#} (spend) time on the train. Tom likes sports news very much. One morning on the train he is reading something about a world football match. The match is very {#blank#}5{#/blank#} (interest). So he forgets {#blank#}6{#/blank#} (get) off the train at his station. He does not know it. When he finishes {#blank#}7{#/blank#} (read), he {#blank#}8{#/blank#} (see) outside. It is far {#blank#}9{#/blank#} his station. He gets off at the next station. He has to go back by train. Of course, he {#blank#}10{#/blank#} (be) late for work.
