It¡¯s an alarming phenomenon that with the increasingly serious air pollution, the air quality in cities is becoming worse and worse. The gases from cars and factories keep coming into the air without being absorbed by enough trees, because trees have been cut down in large quantities. People¡¯s health will be harmed once these gases are taken in, which may cause a series of diseases like lung cancer. To improve the situation, I suggest that the number of cars should be controlled and the factories should be prevented from pouring out wastes. And when we go out, we should try to walk or take public transportations rather than drive our own cars.

¡¾ÌâÄ¿¡¿The weather is getting hotter. You are thirsty playing basketball or riding home from school. A cold drink may be just the thing. But be careful what you are drinking. Something that looks cool may not be good for your health.

There are plenty of "energy drinks" on the market. Most of them have beautiful colors and cool names. The lists on them tell you they are helpful to your health. Sounds great!

But after a careful check you may find that most energy drinks have lots of caffeine (¿§·ÈÒò) in them. These drinks are especially aimed at young people, students, busy people and sports players. Makers sometimes say their drinks make you better at sports and can keep you awake. But be careful not to drink too much.

Caffeine makes your heart beat fast. Because of this, the International Olympic Committee has limited( ÏÞÖÆ) its use. Caffeine in most energy drinks is at least as strong as that in a cup of coffee or tea. Possible health dangers have something to do with energy drinks. Just one box of energy drink can make you nervous, have difficulty sleeping and can even cause heart problems. Scientists say that teenagers should be discouraged from taking drinks with a lot of caffeine in them.

¡¾ÌâÄ¿¡¿It¡¯s been seven days since a 7. 0-magnitude strong earthquake hit Ya¡¯an, in Sichuan Province. How the earthquake has affected one of Sichuan Province¡¯s special residents¡ªpandas. How are the animals coping? And do they have enough food to eat?

There are more than 80 pandas living here at the Chengdu Panda Breeding Base. 7 baby pandas have just left their mothers and have begun to learn how to fend for themselves.

The quake was felt strongly in Chengdu. Fortunately, all of the pandas here were out on the grounds when the earthquake hit, so they were very safe. Although no deaths or injuries have been reported among the Baoxing panda population so far, they¡¯ve been badly frightened by the earthquake. Several days has passed and the earthquake seems to have made no discernible(¿É±æ±ðµÄ)negative impact on the pandas. These two baby pandas Chengshuang and Chengdui are play fighting with each other and climbing trees. When they climbed too high, the breeders have to rescue them from the trees.

The visitors are amused by the scenes and think it¡¯s like a fantastic acrobatics show.

The quake zone is not only the home of these pandas, it¡¯s also the source of their food. Fortunately, enough bamboo has been stored away in five bamboo storehouses for the pandas, so there are no worries with regard to food supplies.

Wu Kongju, Breeder, Chengdu Panda Breeding Base, said, ¡°When the Wenchuan earthquake happened in 2008, we were unprepared and had a shortage of bamboo. But we¡¯ve been able to handle this earthquake event more smoothly. There are no problems with the food supply. ¡±Apart from the pandas¡¯ favorite Baijia Bamboo, breeders also give them bamboo shoots, which are very rich in nutrients.

Wu Kongju said, ¡°Bamboo shoots contain more protein than ordinary bamboo, and they¡¯re also very succulent because they contain more water. ¡±
