              To protect the environment，China has put a ban（禁令） on thin plastic bag （plastic bag thinner than 0.025mm）．From June 1，2008，China stopped the production，sale and use of these plastic bags to the public．
              Plastic bags can cause"white pollution"，because they can take 400-1，000years to break down．They pollute the soil（土壤） and water．Plastic bags also cause a serious danger to animals．Animals often mistake plastic bags for food．Thousands of them die each year after eating plastic bags．
              So what kind of bags will be the best to use when we are shopping？Recently some students made their own shopping bags．Most students used old clothes to make their bags．They painted pictures like the Olympic rings on them．But Li Mei had a more traditional way to make her hag．She weaved（编织） a bamboo basket．It was not an easy job．With her grandfather's help，Li Mei spent the whole afternoon making it．
              What can we do？Refuse plastic bags and persuade（说服） people to use environmentally-friendly （对环境无害的） shopping bags instead of plastic ones．Try to recycle the ones we have．
              61．Did Li Mei make her shopping bag by herself？
              ______
              62．Why do plastic bags cause a serious danger to animals？
              ______
              63．What kind of material did most students use to make their shopping bags？

            • 2． Do you think getting cold can give you a cold？Is it bad to drink milk when you have a cold？
              Ranit Mishori，a family medicine doctor in Washington，says colds are more common in winter，but not because of low temperatures．The cold weather just means people stay inside more．People like staying together and may get the common cold virus if they shake hands，sneeze（打喷嚏） or cough near one another．
              Adults generally get two to three colds a year．Children are likely to catch four or five．Dr Mishori says some people wrongly believe they can become protected from colds for the rest of their life once they get the virus one time．
              There is still no cure for the common cold．But Dr Mishori says there are ways to feel better sooner．
              If you get a cold，you start taking about two grams of Vitamin C a day．There is evidence（证据） that it might shorten the number of days that you will be having the cold．Dr Mishori says honey，bears'favourite food，can also help．She says honey seems especially effective（有效的） in children with colds．
              Have you ever heard the old saying"feed a cold，starve（挨饿 a fever"？Dr Mishori says this is not necessarily a good rule to follow．She says if you have a cold but do not feel hungry，then don't eat．
              According to Dr Mishori，you have to drink a lot．You can drink water or youcan drink tea-anything that gets into your body．That's very important．
              But what about drinking milk during a cold？Mishori says，"Drinking milk during a cold possibly does make you uncomfortable．But clearly if you have a baby and that's all it drinks，you should not stop giving the baby milk．"

              Where does your food come from？How is it made？These days，many people worry about food safety．But food safety is not a new worry．In 1906，Upton Sinclair wrote the Jungle．The book is the story of a poor family in Chicago．It is also about the dangerous ways that food was prepared．People were so worried that the U．S．started testing food．
              These days，most food in the world is safe．Laws control where food comes from．They also control how food is managed and prepared．Laws are important． But it’s more important to make sure the rules are followed．A good food safety system（系统）keeps people safe．It also helps them eat healthy food．Labels（标签）on food give people important information．Then they can make good choices about their food．
              Although food safety systems usually work，there can be problems．Sometimes mistakes are made．For example，a truck might carry eggs and then ice cream．The ice cream could make people sick when the truck isn’t cleaned before carrying it．Other problems are not mistakes．Sometimes companies break rules to make more money．When this happens，people don’t know if their food is safe．
              As we all know，food is closely related to our daily life．We should take actions to make food safer！
