Television With the development of technology, our world is awashed with various media. From comics, books, radio to television, film, theatre which is the most effective one in communicating information? I would say it is television and i will discuss this question in my essay. First of all, television have picture as well as sound which can deliver message or information more accuracy than the first three types (comics, books and radio). And because of this, time are saved by using our sense organ maximumly. Although some individuals might consider it is the accuracy television provid that limited the imagination and render readers or audience capable only to spitting back predigested message, they can`t deny that people spend much more less time as well as energy to finish a TV program rather that a book with the same general idea, constantly. Then, compared to film, television don`t have such strict rules on time. If there is good television programs, I would not bother myself to find a film which cannot be interrupted during several hours unless it is a real brilliant one. And as for theatre, which require quite solid knowledge of literatureI, after spenting almost a whole day to digest the famous theatre, <Much to do about nothing>, I suppose it is too polish to understand for us, so theatre maybe good works of art instead of effective media for information communicating. To conclude, television is cannot be beat in information communicating, as it is convenient, available, time-flexible and straightforward.

Many people think it is very important to protect environment but they make no effort to do it Answer: With the development of technology, our world is full of information as well as contamination. Although we all know the importance of environment protection, few people really take actions preserve it. I will analyse this in my essay. In the first palace, people, who hold the view that commercial advantage overweight the damage bringing to environment, might have not awared of the significance of environment, in which they stay everyday, clearly. Hence, they don`t consider environment is as vital as life itself. In the second palace, some people, catching the importance of environment protection, might regard it as entire human being`s responsibility instead of everyone`s, which make the situation worse. In the third palace, individuals may also suppose that human are too tininess to take this duty and whatever we might do wouldn`t make any sounds. However, if we don`t take it seriously and just let it goes this way, the end of Earth is waiting for us. The solution to this problem is varied: To begin with, we should strengthen environmentally-friendly education, raise the public, including children, awareness of the importance of environment. Then, there should be a formal legal defining the responsbility of citizens in environment preservevation with harsh actions. Last but not least, the government should take the pay for the environment to companies who use renewable resources instead of non-renewable resources, spend money on sewage treating, and protect the environment at high price. To conclude, the best way benifiting environment is to encourage with awards and to punish with penalty, far away from just condemning with nothing or even condoning.
