China had decided to take action to stop the use of plastic bags．Supermarkets, shops and outlets(经销店)in China will not be allowed to hand out free plastic carriers and all plastic carriers must be clearly marketed with prices from June 1．
“People use too many plastic bags every year and fail to deal with them properly, wasting valuable oil and littering the country,”China’s government said in a statement．
While providing convenience for consumers(消费者)，the plastic bags have also caused serious pollution and waste of energy and resources．
“We should encourage people to return to carrying cloth bags, and using baskets for their vegetables．”the statement said．
In addition, the production, sale and use of bags less than 0.025 mm thick is banned from the same date．The firms that break the rules will face fines or confiscation(没收)of goods and profits(利润)．
China also said it would consider increasing taxes(税)to discourage the production and sale of plastic bags and encourage the recycling industry．
Rubbish collectors have to separate plastic for reprocessing and cut the number of plastic bags that are burnt or buried(掩埋)．
The move brings China into line with a growing international trend(趋势)to cut back on the use of plastic bags．From Ireland to Uganda and South Africa, governments have experimented with heavy taxes, with the aim of getting rid of plastic bags．

Are you in shape?To find out, ask yourself some questions：Do I exercise regularly?Do I ever walk places instead of driving my car?Do I ever play sports for fun?Do I ever take the stairs instead of the elevator?If you answered no to any or all of the above questions, you are probably out of shape and need to start a fitness program．
Exercise is very important．It improves your strength and blood circulation(循环)．It gives you more energy．It can help you relax and sleep well, and it can help control your weight．In fact, the U．S．Surgeon General says that exercise can help prevent heart disease, diabetes, obesity, and osteoporosis(a disease that weakens the bones)．
The first step is to make a program．A good fitness program should be fun．It should involve(包含)both your arms and your legs, and it should help you to build endurance(the ability to do exercise for a long time)．To make a good program for yourself, first you should think about the types of activities you like to do, what you think you are able to do, and when you will have time to do it．A good exercise program will involve cardiovascular activities, such as running, biking, swimming, roller skating, playing soccer or tennis, or jumping rope．It will also involve weight-bearing exercise, such as weightlifting, and stretching activities．Also, daily, low-intensity activities such as walking, gardening, dancing, and climbing stairs are good for your physical health．
So what are you waiting for?Get off of the sofa and start exercising．Sign up for yoga, tai chi, or pilates．Join a gym or a running club, or just start walking a half an hour every day．Every little bit helps!
