These days our government is aiming to build an "economized(节省) society".{#blank#}1{#/blank#}(作为) students, you can do something that you can.

 First, save things. You'd better walk to school or {#blank#}2{#/blank#} a bike instead of taking a car. Turn off the{#blank#}3{#/blank#}as soon as you leave the classroom. Remember to turn off the tap right after washing your hands. When you go out to eat in a {#blank#}4{#/blank#} (餐馆), ask for smaller dishes and take leftovers（剩菜）h{#blank#}5{#/blank#}_.Before you buy something new, think {#blank#}6{#/blank#}  it is necessary or not.

 Second, use things for as long as p{#blank#}7{#/blank#} .When you buy things, make sure that they can {#blank#}8{#/blank#} a long time. Don't use a paper cup or a paper bag. It's better to use a china cup because you can use it again.

  Finally, collect what can be{#blank#}9{#/blank#} （回收利用) in your classroom, such as waste paper and soft drink cans. It can save money and protect the environment.

  In general, I think one thing we should keep in mind is that {#blank#}10{#/blank#} matter what a small effort we make, it will make a difference.

You may think there is nothing but sand in the desert of the world, but it is not true. In the desert we can{#blank#}1{#/blank#} stones. We can see hills, too. There is a little rain in the {#blank#}2{#/blank#} , but it is not  {#blank#}3{#/blank#}  for most plants.
　　The animals are{#blank#}4{#/blank#} to the desert people in many ways. The desert people eat the meat and drink the milk of the animals. They use their skins to  {#blank#}5{#/blank#}  shoes, water bags and even tents(帐篷). They use the camels(骆驼) for {#blank#}6{#/blank#} things.
The people of the desert have to keep {#blank#}7{#/blank#}  from places to place. They must always look for grass or desert plants for their animals. They usually live in the tents. When there is mo more food for their animals, they take down their tents, put them on the camels and move to {#blank#}8{#/blank#} place. The desert people are very  {#blank#}9{#/blank#} . No man in the desert would ever refuse to help the people in {#blank#}10{#/blank#} and give them food and water

    There were three old teachers at the railway s{#blank#}1{#/blank#}. They were talking happily. The train arrived, but they didn't notice. Then the conductor(列车长) shouted, “G{#blank#}2{#/blank#}  on the train and take the seats, please”

    The teachers heard the conductor and rushed for the train. T{#blank#}3{#/blank#} of them got on the train b{#blank#}4{#/blank#} it moved. The third one didn't get on the t{#blank#}5{#/blank#}. It was Mr. Green. He looked worried.  One of his students was at the station. He t{#blank#}6{#/blank#} to comfort(安慰) the teacher. It wasn't really b{#blank#}7{#/blank#}, sir,” said the student. “Two out of three c{#blank#}8{#/blank#} the train. That's quite good, you know.”   “I know, “the teacher said, “But it was m{#blank#}9{#/blank#} train. My friends only came to s{#blank#}10{#/blank#} goodbye to me”

    Mrs. Jones is over 80, but she still drives her old car {#blank#}1{#/blank#} a young woman. She loves driving very fast, and she says that she has never broken the traffic rules.

    One day,{#blank#}2{#/blank#}, she nearly broke her record. A police car followed her, and the policeman in it saw her pass a red light without {#blank#}3{#/blank#}(stop).

    When Mrs. Jones came before the policeman, he looked at her seriously and said that she was too old {#blank#}4{#/blank#} (drive) a car, and that her eyes had probably become weak with old age,{#blank#}5{#/blank#}she had not stopped at the red light.

    After the policeman finished his words, Mrs. Jones quietly opened the big handbag she was carrying and took out her sewing (针线活) kit. She {#blank#}6{#/blank#}(choose) a needle (针) with a very small eye, and threaded (穿线) it at her first try.

    When she had successfully done this, she took the thread {#blank#}7{#/blank#} of the needle again and handed both the needle {#blank#}8{#/blank#} the thread to the policeman, saying, “Now it is your turn. You drive a car and you must see clearly.”

    The policeman took the needle and tried to thread it. After trying six {#blank#}9{#/blank#}(time), he still didn't succeed. So Mrs. Jones {#blank#}10{#/blank#} (not punish) and her record remained unbroken.

    An old saying goes, “When in Rome(罗马),do as the Romans do.” I learned the {#blank#}1{#/blank#} of this when I studied in Russia.

    One day I invited some of my Chinese friends to a famous local restaurant in Moscow. My guests and I were {#blank#}2{#/blank#}  from visiting Red Square and happy about our meeting. We had a warm  chat  until  the  waiter  told  me  that  we  were  being  too  loud.  We  turned  our  voices {#blank#}3{#/blank#} .But this didn't last long. The waiter came over to us two more {#blank#}4{#/blank#}  with the same message.

    How bad an impression(印象) we must have left on the local people! In China, it's {#blank#}5{#/blank#}  and important for a host to make a {#blank#}6{#/blank#}  atmosphere(气氛).However, in Russia and {#blank#}7{#/blank#}  countries, having a meal in a public place means you must keep your voice low. You need to be polite to others.

    I felt bad about this. Even though we tried our {#blank#}8{#/blank#} , it's very difficult to develop a new habit.

    Russians have their own special habits. My Russia friend, Andrey always looks around and thinks for a while before leaving home. I asked him why he did this. “Aha,” Andrey said, “in Russia, people always take about a minute {#blank#}9{#/blank#}  over things and plans in their minds before leaving. So they won't leave anything necessary behind.”

    Finding the {#blank#}10{#/blank#}  between cultures is much fun. I'd like to keep my eyes and mind open.

    We all need a healthy environment, but we produce waste every day and it does harm to our environment. {#blank#}1{#/blank#} we are young, we can still do something to help. In fact, even the simplest everyday activities can make {#blank#}2{#/blank#} real difference to the environment. Here are some ideas for you to live a green and healthy {#blank#}3{#/blank#}.

    Remember these three words: reduce, reuse and {#blank#}4{#/blank#}.

    Reduce means "use less". If we stop wasting, we can not only {#blank#}5{#/blank#} money but also reduce pollution and waste. Before we buy something new, think whether it is really necessary or maybe the old one will be just as good! If {#blank#}6{#/blank#}, choose local products and try not to buy too many things from abroad when we do need something.

    Reuse means "use again". Use things for as long as possible. When we buy things, {#blank#}7{#/blank#} sure that they can last a long time. We should take care of them so that they will last long 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(瓷器) cup and lunch box because you can use them {#blank#}8{#/blank#}.

   Recycle means "change things {#blank#}9{#/blank#} something else". Although it takes energy to do this, it's better than throwing things away or burning them. We can do this in many ways. For example, we can find out {#blank#}10{#/blank#} can be recycled in our neighborhood and take part in the recycling programs and we can also buy products made from recycled materials, such as recycled paper to help save trees.
