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.

    People in different countries have different {#blank#}1{#/blank#} （way） of doing things. Something that is polite in one country may be quite{#blank#}2{#/blank#} (polite) in another. In Britain, you mustn't lift your bowl to your mouth when you are{#blank#}3{#/blank#}(have) some soup. But it's different in China. And in Japan you even needn't worry {#blank#}4{#/blank#} making noises when you have it. It shows that you are enjoying it. But it is regarded as bad manners in Britain. If you are a {#blank#}5{#/blank#} (visit) in Mongolia, what manners do they expect you to have? They expect you to have a loud“burp”(打嗝)after you finish {#blank#}6{#/blank#}(eat). Burping shows that you liked the food.

    In Britain, you should try not to put your hands on the table when you're having a meal. In Mexico, however, guests are {#blank#}7{#/blank#} (expect) to keep their hands on the table during a meal. But in Arab countries you must {#blank#}8{#/blank#} (be) very careful with the hands. You mustn't eat with left hand. Arabs consider it very bad manners eating with the left hand. So, what should you do {#blank#}9{#/blank#} you are on a visit in another country? You can ask the native people to help you or just watch {#blank#}10{#/blank#} (careful) and follow them.
