    Water is a liquid (液体) ; but it can also be a solid when it is very cold and turns to ice. It can also be a gas, when it evaporates (蒸发) and become water vapour (水蒸气) .

The water cycle

    Water is very important, and without it life on Earth would be impossible. The oceans that cover three quarters of the Earth's surface can be thought of as our great water reservoirs. All the time, water is being evaporated from the ocean's surface by the warmth of the sun. High in the sky this water vapour, turns into clouds which drift (漂浮) over the land, often creating rainfall. As the rain falls,it seeps (渗漏) into the soil and then into rivers that flow back into the oceans, where it is ready to begin all over again!

    No Car Day was first started by 34 cities in France on September 22, 1998. It was started to protect the environment. By now, more than 1,000 cities around the world have had a No Car Day.

    The first No Car Day in China was in Chengdu in 2001. Other cities including Taipei, Shanghai and Wuhan, also support the day.

    In Beijing, more and more people are taking part in the activity. It asks drivers to leave their cars at home for one day each month and walk or ride a bike to work. It also calls on Beijingers not to use cars on June 5th (World Environment Day). The slogan for the day is, "If we drive for one less day, we can have one more nice day."

    So far, more than 200,000 drivers have shown their support. "We can't control the weather, but we can choose not to drive," said Wu Zhonghua, a car club chairman. Beijing is trying to have 238 blue sky days this year. In the first quarter of 2007, Beijing only had 52 blue sky days. This was 11 days less than the number for the same period last year. Much of the dust comes from the desert, but cars cause most of the air pollution. We must do more for No Car Day.

    In many high schools, there are strict rules about using mobile phones. If your phone rings in class, for example, the teacher will be very angry.

    Every mobile phone has a ringtone (铃声). It tells you that someone is calling you. Now, there is a ringtone called “mosquitotone (蚊子铃声)”.

    Mosquitotone has a special sound. Only children and teenagers can hear it. As we get older, we are unable to hear some sounds with high frequencies (频率). As a result, a child or teenager can hear the mosquitotone ringtone, but someone of 20 or older can't.

    But sometimes, people over 20 can hear the ringtone. One British student's phone uses mosquitotone. In class, the student's phone rang. The 22-year-old teacher looked at the student and became unhappy. “I heard that. You know the rule：no mobile phone in class. ”

    Not all the students are interested in mosquitotone. Jerry Jones, a high school student of 17, says, “Using mosquitotone too often is bad for our hearing. I may use it for pleasure, but not in class. It's unfair(不公平的) to the teachers！”

    What do parents think of mosquitotone？“I think it is perfect for places like movie theaters,” says Connie Neeson, 44. “Think about it. You're watching a film and someone's mobile phone rings. Mosquitotone is good because many people don't hear it. However, it also has a bad influence（影响） on their study if students use it in class. ”

    I used to shower with soap every day, but my skin(皮肤)always felt dry and itchy(发痒的). Then two months ago, I heard of the no-soap movement. Since then, I've given up using soap in the shower. I still shower every day. I just don't use soap because it's filled with chemicals.

    So, what's so bad about using soap? Well, the chemicals in soaps can be harmful to our health. So, if we use soap, our skin will take in the chemicals, which will then end up in our bodies. According to the scientists, some of the chemicals used in a soap are quite dangerous. During my research, I also learnt that soap removes moisture(水分)from the body. This is actually why my skin was so dry and itchy.

    Getting used to washing my body without soap was a huge change. For the first week, I felt a bit dirty and I didn't smell great, either. However, during the second week, my skin felt clean without strange smell. Best of all, my skin problems disappeared, and now I have softer and healthier skin.

    On the whole, going soap-free has not only saved me time and money, but has also improved my skin. What's more, this experience has made me take a look at some of the other products I use in the shower, such as shampoo. More about that in my next blog!
