    Did you see snow in your hometown last winter? Did you feel it was warmer than before? "There have been

21 warm winters in China since 1986," said scientists. They also said that in the past 100 years, as the global

(全球的) temperatures went up by 0.74 °C, the temperature in North China has climbed 1.4 °C in only 50

years.

    China needs to take quick action to cut carbon dioxide (二氧化碳) emission (排放), because it's the main

reason for global warming. The good news is that China has seen the importance of going green. China set the

goal of cutting energy use by 20 and pollution emission by 10 in the 11th Five-Year Plan.

    Can you slow global warming? Sure! You and your family can take steps to cut the amount of carbon

dioxide that is sent out into the air.

    Here are some pieces of advice to help you save the earth.

    Wear used clothes. Wearing your brother's, sister's or dad's old T-shirt means you save the energy.

    Change your light bulbs (灯泡). Use energy-saving light bulbs. And don't forget to turn off the lights when

you leave a room and turn off your television and computer when they are not in use!

    Ride the bus. Taking a bus saves a lot of oil every year.

    Say no to plastic bags. The next time your parents go to the market, ask them to use baskets

    Open a window. Don't use the air conditioner (空调), and let some fresh air in. When you have to use the

conditioner, set the temperature higher in the summer and lower in the winter to save energy.

    Make small changes in your daily life. Don't use paper cups, bags and boxes. It's time for all of us to do

something to save the earth.
