    Every year animals all around the world take part in some wonderful journeys．Here are the stories of two amazing animal travelers．

    Humpback whales （ 座 头 鲸 ） prefer a slow journey．The humpbacks，

    which travel over 10，000kilometers on their journey from Alaska to Hawaii，swim at a relaxing speed of about 1.6kilometers an hour．Although they don't swim fast，humpback whales travel farther than any other kinds of whale．

    Every August a fantastic sight can be seen in the skies above Ontario and Montreal﹣millions of amazing Monarch butterflies （ 帝 王 蝶） beginning their 4，000﹣kilometer journey from Canada to Central Mexico．In fact，the journey，which takes about 3months，is longer than the average （ 平 均 的 ） life of the butterfly．Finally many of the butterflies reaching their final place are the great grandchildren or even the great great grandchildren of the butterflies who began the journey in Mexico the year before．

Doing "Clean "Exercise

    When you go for a run outside, chances are that you'll find litter all around you. Do you just go past it, or do you stop and pick it up? If you choose the second, you're part of the latest popular sport in the West: plogging.

    The word "plogging" is the Swedish phrase" plocka upp"（ pick up） and the English word "Jogging"(running slowly)put together.

    What a plogger needs is a rubbish bag and a pair of gloves to protect your hands. While collecting rubbish, ploggers learn to classify (分类)and deal with it correctly, too.

    Plogging seems simple but it does a lot of good to both the environment and your health. It can not only make the world greener, but also get you full body exercise, For example, a 30-minute logging burns around 288 calories（卡路里）， compared to 235 calories burned from just jogging.

    So next time you go out jogging, why not carry a rubbish bag and collect some litter along the way? Your body and the environment will thank you.

    Mr. Reynolds, my teacher, handed us a list of thoughts, and asked us to write a paper on one of those thoughts. I chose the topic" I wonder why things are the way they are."

    I wrote down all the questions that puzzled(困扰)me about life. I realized that many of them were hard to answer，and perhaps others could not be answered at all. When I handed in my paper，I was afraid that I might fail because I did not answer the questions.

    The next day, Mr. Reynolds handed me the paper and asked me to read it for the class. The other students became quiet as I began to read my story：

    Mum, why are the roses red? Why is the grass green and the sky blue? Why do I have to graduate(毕业)？Why do I have to grow up? Why do I have to be called "Grandma" one day？

    Dad, why can't I stay out until 12: 00? Why do I miss my old friends? Why do I miss being at home? Why do you love me so much？

Mum, Dad, why did you have to leave me? I need you.

    At the end of my story, I looked at Mr. Reynolds, and I saw a tear slowly coming down his face. Then I realized that life is not built on the answers we receive, but on the questions we ask.

    If you dropped a piece of fruit on your computer keyboard, would you think about eating it again? What if you dropped it in the toilet? Bacteria can live everywhere, even in some unexpected places.

    If you eat at your computer, sneeze on your keyboard, or sit down to surf the Internet without first washing your hands, your computer keyboard could be bad for your health. According to the US National Research Centre, the average computer carries 400 times more bacteria than a toilet bowl does.

    Could one of the dirtiest things in your home be right in your hand? Yes: the TV remote control. It gets dropped on the floor, put on the sofa and everyone in the house holds it. Scientists found that about half of the tested remote controls carry the cold virus.

    Don't forget your toothbrush. Do you put it in the bathroom? Studies show that flushing the toilet releases bacteria in the air. Bacteria can remain in the air for at least two hours. They may pollute your toothbrush. You can find ways to solve this problem. Try to keep your toothbrush far from the toilet. Make sure that it is in an upright position after each use. It's also important to change your toothbrush every three months.

    Here are some other places to watch out for:

    At home

    The kitchen is one of the places with the most bacteria—more than the bathroom. Dishcloths and kitchen sponges are great places for bacteria since they are always wet after being used. Try to make them dry.

    At school

    When you put your schoolbags on the floor or in the bus, many bacteria can live on the bottom of it. Try to clean your schoolbag often.

    In public places

    Escalator handrails, shopping cart handles, public books and magazines are top bacteria carriers. That's why the first thing to do when getting home is to wash your hands.

    Yes, bacteria are everywhere. But don't be too afraid to touch those things. Most of bacteria are harmless. Just remember to wash your hands regularly. It is the most useful way to protect yourself from bacteria and viruses.
