night into day ever since. But today, many want to turn the light off.
The European Union (欧盟) recently decided that by 2009, people should stop using the Edison-style light
bulb. Instead, they should use compact fluorescent lamps (小型荧光灯, CFLs节能灯).
"CFLs save energy and last longer. They can save money in the long run," said a British official. CFLs use
67 percent (67%) less electricity than the older bulbs. They last up to 10 times (倍) longer. Scientists say that
if everyone used CFLs, electricity use would be cut by 18 percent. There would also be much smaller amounts
of greenhouse gases (温室气体) given off.
But it"s difficult to make people change their lighting habits. First the CFLs are more expensive. They cost
eight times the price of the older bulbs. Many people don"t like the CFL bulb. They find it too bright. You
cannot change the light of a CFL, either.
CFLs have been around for several years. However, the older lights still make up about two-thirds (2/3) of
total (全部的) light bulb sales.
( )2. Countries in the European Union will not use Edison-style bulbs by 2009.
( )3. Using CFLs helps protect the environment.
( )4. If you get an older bulb for l Euro (欧元), the CFL bulb will cost you 8 Euros.
( )5. CFLs have been widely used instead of the older bulbs for several years.

long and weigh up to 160kg. People think the giant panda is very lovely. ①So it is not surprising that the World Wide Fund for Nature chose the giant panda as its symbol. The WWF tells people about animals that they are
in danger and raises money to save them.
The giant panda only lives in the wild in China. In the early 1980s, were only 1,000 left in the wild. The
main reason why pandas are endangered is that the area where pandas can live has become smaller.
The WWF works to help giant pandas in the wild in many ways. One of the ways that helps them is to
increase the size of panda reserves (自然保护区). Some reserves need to be joined together by planting
bamboo between them to make "corridors". These are paths that lead from one reserve to another. No one may
harm the pandas in these areas. The corridors let pandas move from one habitat (栖息地) to another to look
for food. ②People are working very hard to make sure the giant panda does not die out.

and so is the traffic in around the cities. Something will have to be done to change it. What will the cars of
tomorrow be like? Little cars may some day take the place of today"s big cars. If everyone drives little cars in
the future (将来) there will be less pollution (污染) in the air. There will also be more space for parking cars in
cities, and the streets will be less crowded. Three little cars can fit (适合) in the space now needed for one car
of the usual size.
The little cars will cost much less to own and to drive. Driving will be safer, too. What is more, these little
cars can go about 65 kilometers per (每) hour.
Little cars of the future will be fine for getting around a city, but they will not be useful for long trips. If big
cars are still used along with the small ones, two sets of roads will be needed in the future. Some roads will be
used for the big, fast cars, and other roads will be needed for the slower small ones.

| Healthy Eating Healthy eating is important to us. What and how should we eat to be healthy? First, we must have enough food, never too much or too little. The food must be clean and we should cook it properly. Second, it"s very important for us to keep a balanced diet. Different kinds of foods are necessary, such as rice, bread, meat, fish, eggs, milk and vegetables. Rice and bread give us energy. Meat, fish, eggs and milk help our bones grow. Fruit and vegetables make us healthy. Third, we should eat regularly. It"s said that half of the students don"t have a regular breakfast or don"t eat anything at all in the morning. It is bad for their health. In fact, a good breakfast keeps us strong. In short, we should not only eat enough food, healthy food but also eat regularly. | |||

| We all need a healthy environment, but we produce waste every day and it does harm to our environment. Though we are young, we can still do something to help. In fact, even the simplest everyday activities can make a real difference to the environment. Here are some ideas for you to live green life. Remember these three words: reduce, reuse and recycle. Reduce means"use less". Don"t waste things. This saves money and reduces pollution and waste going into the environment. Before we buy something new, think if it is really necessary or maybe the old one will be just as good! When we do buy things, choose local products if possible, and try not to buy too many things from abroad. Reuse means"use again". Use things for as long as possible. When we buy things, make sure that they last a long time. We should take care of them so that they will last, and we should repair them if we can instead of throwing them away and buying new ones. Don"t use a paper cup or a paper bag. It"s better to use a china cup and a lunch box because you can use them again. Recycle means"change things into something else". Although it takes energy to change something into something else, it"s better than throwing things away or burning them. Find out what can be recycled in your neighborhood and take part in recycling programmes. We should also buy products made from recycled materials, such as recycled paper, to help save trees. | |||
