We eat food with the help of hands every day. It is possible for some germs(细菌) to get into our bodies. So it is important to know how to wash hands in the right way.

    A piece of news from CCTV says that students from Guangzhou have a good way of learning how to wash hands. They learn it through doing hands-washing exercises during the ①break. The teachers there say most students wouldn't like to listen but they like to act. So now the students are interested in the interesting exercises. They are learning carefully. ②They want to be teachers for their parents and friends after they learn them well.

    "Never set foot in this house again!" should father." BANK!" the door closed behind me. With tears in my eyes, I rushed out of the flat and ran along the street.

    The street lights were shining, causing rather sad-feeling. {#blank#}1{#/blank#} I don't know whether it is because I have grown up or because dad is getting old. We differ in our ways of thinking. He always put his opinions on me. We are just like two people coming from two different worlds. {#blank#}2{#/blank#} I wandered the streets, without any aim in my mind. As I walked on there were fewer and fewer people on the streets. When I finally reached the apartment where I lived, I saw that the light was still on.

    I thought to myself: Is father waiting for me, or is he still angry with me?

    In fact, it was nothing. Perhaps, dad was throwing away some of his old stamps. Perhaps he thought they were useless. {#blank#}3{#/blank#} All the lights were off except father's.

    Dad was always like this. He had got used to arguing with me. {#blank#}4{#/blank#} After shouting at me, he never said sorry to me. But after an argument he always came into my room secretly and made sure whether I was asleep.

    The light was still on." Am I wrong?" I whispered, maybe… With the key in hand, I was as nervous as I had ever been. At last, I decided to open the door. As soon as I opened the door, tears ran down my cheeks. {#blank#}5{#/blank#} Love is second to none.

A. It feels like there is an iron door between us that can never be opened.

B.I wandered aimlessly.

C.I suddenly realized that the iron door that I had imagined between us did not exist at all.

D. Maybe he didn't know how to express himself.

E.I never had the courage to tell him that I liked collecting stamps.

    March 20th is World Water Day every year. According to a report from the United Nations, more than half of the world's major rivers have serious water loss and are polluted.

    The Yellow River, the world's fifth longest river, watered some of the oldest farms on earth. {#blank#}1{#/blank#}Its source（源头）on Qinghai-Tibet Plateau is drying up. In most of the past 35 years, it didn't reach the sea.

The Nile in Egypt, running 6, 650 km, is the longest river in the world. {#blank#}2{#/blank#}Now it is down to 2 billion m³ or so. Australia's Murray River reaches the sea only every other year. One fifth of America's Rio Grande has no water, either.

    {#blank#}3{#/blank#}

    Mostly it's damming（筑坝）and global warming that make rivers dry. {#blank#}4{#/blank#}Now about 45, 000 of them lie across the world's rivers. They hold back around 15% of the world's fresh water from running to the sea.

{#blank#}5{#/blank#} Warmer weather takes water away. The glacier（冰川）are becoming smaller. The source of the Yellow River is drying up because of it. Global warming has had certain effects on water sources. Droughts happening around the world make people pay more attention to this fact.

    Language is always changing and developing. This isn't a bad thing. If English hadn't changed for a long time, we won't have words to describe telephones, washing machines, computers or some other new things.

    Language changes for several reasons. First, it changes because the needs of its speaker change. New technologies, new products, and new experiences need new words to express them clearly. Another reason for change is that different people have different language experiences. People use different sets of words and expressions, because they have different ages, jobs, education levels(水平) and so on.

    How does language develop then? On the one hand, many of the languages changes begin with young people. When young people communicate with others of their own age, their language grows in grammar, words and expressions that are different from the older people's. Some have a short lifetime but others can influence the language for long. On the other hand, we get new words in many different ways. We borrow them from other languages, we create them by making words shorter or combining words and we make them out of proper names.

    Languages that don't change over time are considered dead languages. The fact that English changes so much shows that it is alive and well.

    Nobody likes to do chores, especially kids. How can you make your kids get into a good habit of doing their chores? Try making chores fun for them.

    Play some music: Music makes everything seem like a party, doesn't it? ③Play your kid's favorite music that they can dance to while they are doing their chores.

    Make it a treasure hunt(寻宝): It's a good way when you would like your kids to clean the house. Let them know that you hide(隐藏) a ＄5 bill someplace. If they find it, they can keep it.

    Change often: If your kids keep doing the   ①     chores for months, they may feel    ②   (无聊的，厌烦的). Teaching them a new task(任务) is fun for both you and the kids. They will feel more grown-up when they get a new task.

    Do it together: It's never fun to be the only one working and watch everyone else relaxing. ④If everyone takes part in(参加) doing chores, your kids will finish them faster and have more fun.
