We all need a healthy environment, but we produce waste every day and it{#blank#}1{#/blank#} our environment. Though we are young, we can still do something to help. In fact, even the simplest {#blank#}2{#/blank#}activities can make a real difference to the environment. Here are some ideas for you.
Reduce means "use less". Don't waste things. This {#blank#}3{#/blank#} money and reduces pollution and waste going into the environment. Before we buy something new, think {#blank#}4{#/blank#}it is really necessary—or maybe the old one will be just as good! When we do buy things, choose local products if {#blank#}5{#/blank#} and try not to buy too many things from abroad.
Reuse means "use again". Use things for as long as possible. When we buy things, make sure that they {#blank#}6{#/blank#}a long time. We should look after them{#blank#}7{#/blank#} they will last and we should repair them if we can instead of throwing them away and buying new ones. Don't use a paper cup or a paper bag. It's better to use a china cup and a lunch box because you can use them {#blank#}8{#/blank#}.
Recycle means "change things into something else". Although it takes {#blank#}9{#/blank#} to change something into something else, it's better than throwing things away or burning them. Find out what can be recycled in your{#blank#}10{#/blank#} and take part in recycling programmes. We should also buy products made from recycled materials, such as recycled paper, to help save trees.

    In my {#blank#}1{#/blank#} (看法)，helping others is helping ourselves. This story tellsus the truth.

    One day, a {#blank#}2{#/blank#} （口渴的）bee went to a river to drink. As he was drinking, suddenly the beewas carried away by the running water in the {#blank#}3{#/blank#} （小溪）. He tried his best to swim towards the bank of the river, but {#blank#}4{#/blank#} （失败）. His life hung by a single thread. Just at that time, a kind birdflew over. Seeing that the bee was in great {#blank#}5{#/blank#} （困境）, the bird picked a leaf off the tree and threw it into the river.The bee climbed onto the leaf and it was {#blank#}6{#/blank#} （带来）safely to the land. He was so thankful to the bird for saving hislife.

Not long after that, the bird was sitting onthe branch of a tree. He didn't know that not far from him, a man raised hisgun and was about to shoot at {#blank#}7{#/blank#} （他）. However, it happened that the bee saw that. He {#blank#}8{#/blank#} （意识到） what the situation was like . As quickly as he could, he flewinto the man's {#blank#}9{#/blank#} （眼睛）and stung him. The pain in his eyes was so great that the man hadto give up shooting at the bird.

    In this way, the bee, whose life had been saved by the bird, was {#blank#}10{#/blank#} （能） to save the life of the bird.

    Joe and Jack are {#blank#}1{#/blank#} (谈论) about the year 2020. "What will our world be like in the year 2020?" "I don't know," says Jack. "What do you think?" "Well, no one {#blank#}2{#/blank#} (知道), but it's interesting to guess." "In the year 2020, {#blank#}3{#/blank#} (千) of people will buy a pocket computer. The computer will {#blank#}4{#/blank#} （改变） people's life. They will give people the answers to all their questions. We shall all have {#blank#}5{#/blank#} (电话) in our pockets, too.

    And we'll be {#blank#}6{#/blank#} （能够） to talk to our friends all over the world. {#blank#}7{#/blank#} (也许) we can see them at the same time." "A lot of people will live and work under the sea. Perhaps there will be big towns, factories and farms under the sea, too." "{#blank#}8{#/blank#} (机器) will do most of the work, so people will have more {#blank#}9{#/blank#} (空闲的) time, perhaps they'll work only two or three days a week. They can fly to the moon by spaceship." "I'm looking forward to {#blank#}10{#/blank#} (参观) the moon!" "And I hope I can live under the sea." says Jack " Won't that be interesting? Just like a fish!"

    Who designed (设计) the first helicopter (直升机)? Who{#blank#}1{#/blank#} one of the most famous pictures in the world? Who knew more about the human body than most {#blank#}2{#/blank#}? There is an answer to all these questions——Leonardo da Vinci. You might {#blank#}3{#/blank#}what I said, but it is true.

    Leonardo was a great genius (天才). He didn't study at a(n){#blank#}4{#/blank#}. About 1,500 years ago, he lived in Italy. He had lots of {#blank#}5{#/blank#}. One of them was inventing (发明) things. One of his notebooks had drawings of a helicopter. Of course, he wasn't {#blank#}6{#/blank#}to build a helicopter with the things he had. But{#blank#}7{#/blank#}said his idea worked.

    Leonardo wasn't just an inventor. He enjoyed painting. He was one of the greatest {#blank#}8{#/blank#}of his day. When he was young, he was an excellent painter. As he {#blank#}9{#/blank#}he became more famous. Many of Leonardo's wonderful{#blank#}10{#/blank#}are still with us today, for example, the smiling woman the Mona Lisa.
