1、FOOD SAFETY,Presenter: LI Li 2010-06-10,Nowadays, people are more and more concerned about whether or not the food that they eat is actually safe for their consumption, brought on by the tainted milk powder scandal that started in October. In your opinion, what can be done to get safe food in China?

2、,America is growing older. Fifty years ago, only 4 out of every 100 people in the United States were 65 or older. Today, 10 out of every 00 Americans are over 65. The aging of the population will affect American society in many ways - education, medicine, and business. The graying of America has mad

3、e us a very different society -one in which people have a quite different idea of what kind of behavior is suitable at various ages. A persons age no longer tells you anything about his or her social position, marriage or health. Theres no longer a particular year in which one goes to school or goes

4、 to work or gets married or starts a family. The social clock that kept us on time and told us when to go to school, get a job, or stop working isnt as strong as it used to be. It doesnt surprise us to hear of a 29-year-old university president or a 35-year- old grandmother,or a 70-year-old man who

5、has become a father for the first time. Public ideas are changing. Many people say,l am much younger than my mother or my father was at my age. No one says anymore, Act your age. Weve stopped looking with surprise at older people who act in youthful ways.,Have you got any online shopping experiences

6、? What do you think the advantages and disadvantages of online shopping are? If you have a chance to set up a shop online, what kind of shop will you choose?,In recent years with the development of economics, more and more people have been richer than before, and most of them would like to choose to

7、 travel in their holidays to widen their eyesight, increase their knowledge and relax themselves. Tourism has bring benefits definitely for all of us. However the main disadvantage of tourism is that it also do harm to the environment, more and more attention are paid to this issue. I will explain m

8、y point of view from the two aspects as follows.,First of all the garbage pollution should not be ignored. While the tourist are enjoying the journey, some of them leave about many rubbish such as plastic bags which can not be decayed for many years. The litters made the landscape not beautiful as b

9、efore, and m Secondly the water and the air is not clear than before. For example in jiuzai valley more and more travelers have made the is also polluted in jiuzai valley and the air is not clear as before. the most harm to the environment is the rubbish (pollutant garbage waste) produced by the tou

10、rist such as the plastic bags, which can not be decayed for many years.,With the development of technology, online shopping has become popular in peoples daily life. As many of us might have witnessed, more people are buying products through the Internet. And to facilitate online purchase, stores pr

11、ovide pictures of their products together with other illustrations on the websites. Besides, online products range from small items such as clothes and books to large ones like computers.,Considered as smokeless industry, tourism nowadays becomes the leading industry in the tertiary industry with th

12、e relative abundant of material and the corresponding development of peoples living standard. However, when Fairytale Jiuzhai Valley suffers from the premature decay of its karst lake, when Huangshan Mountain are spread all over by litters, when zhouzhuang becomes the typical negative example of ove

13、r tourism development leading to constructive destruction, we have to think twice about the affect tourism exerting on environment.,First of all, tourism, as an immeasurable model to bring profits, is of significance to the environment. On an island such as Madeira, tourism is, to quote the European

14、 Unions European Employment Service, “the regional economys principal motor and greatest source of revenue”, even beyond its hotels. Without the tourists, Madeiras wine and embroidery industries would suffer, as would the islands 2,000 wicker weavers (it is tourists who mostly buy their work). This

15、in turn would affect the landscape another of the islands attractions for there would be no industry left to steward the willows and eucalyptus, neither of which are indigenous and which would begin to encroach and in time destroy the Laurissilva forest that has been there more than 10,000 years. Th

16、us, we are informed that the money tourism gains are of great help to environment preservation.,Crucial continuing is the point that improper tourism would be the hazard to the environment. Excessive tourism would not only cause the air pollution, water pollution and solid waste which jeopardize loc

17、al residents and tourists, but also result in an inappropriate use of local flora and fauna resources, leading to the ecological structural imbalance. Not to mention the disturbance to the local living environment and the imperilment to the tourism environment including Cultural Relics and Historic

18、Sites recourses. According to the statistics, there are already 44% of our tourism zones are encountered with the garbage pollution, 12% are struggling against water pollution, noise pollution occurs in 11%, air pollution are invading 3%.,Taking all this factors into consideration, tourism can be a

19、good model for nature conservation and economic development if it is managed with the well-being of local ecosystems and human communities in a moderate way. Bring financial sources to local nature conservation, tourism can be a supporter but foe to the environment.,Undoubtedly, online shopping has

20、brought us many conveniences. Yet its potential dangers to the consumer could not be ignored. One possible risk is that consumers might not get the exact product they want because the information provided might not be enoughorreliable. For a simple example, a consumer who wants to buy a pair of shoe

21、s might end up getting a pair with desired style but unfit sizes. After all, people have to try themselves when buying clothesorshoes. Moreover, if consumers do not pay attention to the credibility of online stores, they might get cheated.,Therefore, consumers should firstly be aware of the credibility of an online store. Secondly, people should not jump on the bandwagon because not all online shopping brings about convenience. Instead, they have to make their own judgment as to the kind of products that could be bought online. Thus, they could avoid possibl
