手机的利与弊
Nowadays,with the rapid development of IT and information industry, cell phones play a dominant role in towns people's life. But, like everything else, they have both favorable and mffavorahle aspects.
First, it's useful. As a wireless mobile telephone, it's easy and handy to early to wherever one goes and call the callee however far away he is. Therefore, it greatly facilitates people's life. Second, it's convenient. Whenever one meets trouble or something urgent, one can nmke a call immediately. Most important of all, it's a very helpful companion. With a multirfunction cell phone in hand, one can easily get on the Net, browsing the useful information, conducting e-commerce and doing whatever one can do via Internet.
However, just as everything has two sides, the cell phone also has many disadvantages. To begin with, it's expensive to buy and costly to pay the hills, esp. that of global service. To make matters worse, it's also easy to lose and costly to get it repaired. Worst of all,it's not as clear as a family telephone and sometimes the number dialed is often not available. Last but not least, it's alleged the microwaves in it might do harm to people's health.
In my opinion,with its expenses greatly reduced after China's entry into the WTO, it will face an ever brighter future in its development. Someday most of them will be developed into new Intemet-enabled mobile phones, which will be as useful as pocket computers. And I believe its advantages will not only offset its disadvantages, but also far outweigh them.
food safety
People can not live without food every day, so food safety becomes our top concern naturally.
The importance of food safety is undisputed. We absorb nutrition from our diet which has a central role to play in ensuring our health. What’s more, health statistics clearly indicate that our health is closely associated with the quality of food. Nowadays, we purchase food from markets, so the food safety there would be of key importance.
In my opinion, while commercially prepared food is usually safe, rare accidents do occur, however, things often go contrary to our wishes since we are the witnesses of a string of incidents of food safety problems happening in China, ranging from the industrial dye of tofu to the notorious melamine-tainted milk powder. So serious are the accidents that even some victims lost their lives. Rapidly, these series of incidents focused the national spotlight on the food safety in our daily life. Obviously, it is the certain kinds of illegal food additives that pose severe dangers to the general public.
Luckily, our government is very concerned about food safety. In recent years, it has passed laws and regulations on food safety and special offices were established to oversee the food safety problems. Also, as consumers, our efforts will be a good contribution to eliminate these problems, too. Only when food safety isn’t a troublesome thing any more, can we have a bright future.
