Every time I see people riding bicycles on the street, I always think of the time I {#blank#}1{#/blank#}(spend) on my grandpa's old bike.

    When I was little, my grandpa looked after me because my parents were both busy {#blank#}2{#/blank#}their work. At that time, only a few people {#blank#}3{#/blank#}(have) cars. Most people usually got around {#blank#}4{#/blank#}bike. And how did I go to the school then? Yes, I went there on Grandpa's bike! {#blank#}5{#/blank#}the bike was moving forward, it made some funny sounds that made me {#blank#}6{#/blank#}(laugh). I always clapped my little hands and sang {#blank#}7{#/blank#}(happy). Grandpa turned back over and over again to make sure my little feet would not get caught in the wheels. Grandpa was so careful {#blank#}8{#/blank#}I never got hurt in his care.

    {#blank#}9{#/blank#}a sweet memory it is[ Now, I am studying in a boarding school and I miss my grandpa a lot. I wish I could relive those old {#blank#}10{#/blank#}(day).

    The topic of this programme is environmental protection. We human beings {#blank#}1{#/blank#}(do) a lot of things at the cost of the environment to develop economy quickly in the past few years. I do think it is time for us to understand the {#blank#}2{#/blank#}(important) of protecting the environment and do something about it. And today I would like {#blank#}3{#/blank#}(introduce) some simple but useful ways that we can follow {#blank#}4{#/blank#}(easy) in our daily life. Firstly, turn {#blank#}5{#/blank#}lights if it is unnecessary. Then, go out in environment﹣friendly ways such as by bus, by subway or by bike. We can even walk to work when possible,{#blank#}6{#/blank#}it is really helpful for both of our budget and health. Thirdly, try best to {#blank#}7{#/blank#}(use)things like books, paper, magazines and so on. And we can also take a cloth bag when we go {#blank#}8{#/blank#}(shop). Please don't use plastic ones. Of course the public should raise environmental awareness and realize it is {#blank#}9{#/blank#}(everyone) duty to protect the environment. Last but not least, the government should make laws to guide people's {#blank#}10{#/blank#}(behave).

    Great inventions change the world. They help people live {#blank#}1{#/blank#}better life. The wheel is perhaps the {#blank#}2{#/blank#}(great) invention in history. After its invention, travelling became faster and {#blank#}3{#/blank#}(comfortable). Without the wheel, we would not have carriages, trains and {#blank#}4{#/blank#}(car). In 1867, the telephone, one of the most {#blank#}5{#/blank#}(practice) inventions, was invented. Alexander Graham Bell was its {#blank#}6{#/blank#}(invent). Since then, people {#blank#}7{#/blank#}(be) able to speak to each other over long distances. Mobile phones allow people to keep in touch {#blank#}8{#/blank#}each other anytime, anywhere. Thomas Edison {#blank#}9{#/blank#}(develop) the practical light bulb in 1879. With light bulbs, people can do as many things in the evenings {#blank#}10{#/blank#}they can in the daytime.
