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 temperature went up by 0.74℃, the temperature in North China has climbed 1.4℃ in only 50 years.

China needs to take quick action to cut carbon dioxide emission, 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 percent and pollution emission by 10 percent.

Can you slow down 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. 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.

Maybe you are an average(一般的) student. You probably think you will never be a top student. This is not necessarily so, however. Anyone can become a better student if he or she wants to. Here's how.

Plan your time carefully. When planning your week, you should make a list of things that you have to do. After making this list, you should make a plan of your time. First, your time for eating, sleeping, dressing, etc. Then decide a good, regular time for studying. Don' t forget to set enough time for entertainment(娱乐). A weekly plan may not work out all your problems, but it will push you to realize what is happening to your time.

Find a good place to study. Look around the house for a good study place. Keep this space, which may be a desk or simply a comer of your room, free of everything but study materials(材料). No game, radio, or television! When you sit down to study, concentrate(集中精力) on your subject.

Make good use of your time. Listen to everything the teacher says. Really listening in class means less work later. Taking notes will help you remember what the teacher says.

Study regularly. When you get home from school, go over your notes. Review the important points that your teacher has mentioned in class. If you know what your teacher is going to discuss the next day, read that material. This will help you understand the next class. If you do these things regularly, the material will become more meaningful, and you will remember it longer.

Develop a good attitude(态度) to tests. The purpose(目的) of a test is to show what you have learned about a subject. They help you remember your new knowledge. The world won't end if you don' t pass a test, so don't be overly worried.

There are other ideas that might help you with your studying. You will probably find many others after you have tried these.
