    Four ways to have a good school life

    Your schooldays should be some of the best and happiest days of your life. How can you get the most from them, and be sure you do not waste (浪费) this great chance to learn?

Be active(积极的) at school

    Don't say things are difficult or boring. Take interest in school life and your school subjects. Join lots of activities. Put up your hands quickly in class. Go around the school with a big smile. If you are not working, you are wasting your time at school. Teachers cannot make everything enjoyable（令人愉快的）.

Keep fit

    If you don't eat a good breakfast, you will be thinking about food in class. If you go to bed late and don't have enough sleep, you will be sleepy in class. Play enough sports every day in order to keep your body strong.

Face the problem

    Do not say you will do things tomorrow. If you get behind the class, it is very difficult to get back in front. You cannot finish the race if you rest all the time. Everyone fails some exams, loses some matches and has bad days. Don't make small problems very big and important. Don't forget to ask for help. You are young, and no one thinks you must do everything quite well!

Spend the weekends

    Don't waste time lying in bed on Saturday or Sunday morning. Go and play sports, get together with friends in the park to relax, learn to play the piano, or help someone with problem. If you don't want to go out, there are also a lot of things to do. You may read a book, practice English or help Mum with housework.

    Follow our advice, and have a happy school life!

    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 （干旱） happening around the world make people pay more attention to this fact.

    Great white sharks in the Pacific Ocean. Wildebeest (角马)in Africa. Arctic terns(北极燕鸥) in the Atlantic. At first, these animals seem quite different. One swims, one walks, and the other flies. But they all have one thing in common, They all migrate(迁徙).

    Some migrating animals move to a place with a better temperature. Some go to find food or water. The groups travel as one, but during the trip, they face many different challenges.

    One challenge is distance. Some migrating animals take very long trips. For example, one great white shark swam from Australia to South Africa and back. In nine months, it swam about 20, 000 kilometers!

    Another challenge is finding enough food and water during the journey. For example, each Mali elephant needs over 200 liters of water each day. To get this, they need to go from one waterhole to another.

    Besides, migrating animals have to keep away from other animals that want to eat them. The zebra (斑马) has to avoid lions. Traveling as a group helps keep them safe. When one zebra is in trouble, the other members make a circle around it.

    By working as a group, migrating animals travel to live better lives.

    Mr Brown was at the theatre. He had got his ticket at the moment, so he had not been able to choose tis seat. He now found that he was in the middle of a group of American ladies, some of them middle-aged and some of them quite old. They clearly all knew each other well, as before the curtain went up on the play they bad come to see, they all talked and joked a lot together.

    The lady sitting on Mr Brown's left, who was about sixty years old, seemed to be the happiest and the most amusing of the American group, and after the first act(幕)of the play, she apologized to him for the noisiness of her friends. He answered that he was very glad to see American ladies so obviously enjoying their visit to England, and so they had a friendly talk. Mr Brown's neighbour explained what they were doing there.

    "You know, I have known these ladies all my life, "she said. " We all grew up together back in our hometown in the United States. They have all lost their husbands, and call themselves the Merry Widows(寡妇). It is a sort of club, you know. They go abroad every summer for a month or two and have a lot of fun. They always go everywhere together. I have wanted to join their club for a long time, but I didn't qualify(具备……的资格)for membership until the spring of this year. "
