Some people may think that having some valuable food like abalones and shark fins can show others how wealthy they are. However, they are ignorant to the damages they have made to the marine lives or even the ecosystem. Even some people realize that over-exploitation of marine resources will lead to ecological and environmental problems, they do nothing to pay for the loss of the ecosystem.

  Take shark fins as an example, the problem of over-fishing is extremely serious in the Meditteranean Sea. This region is known as the most dangerous place on Earth for sharks and rays according to the report published by the World Conservation Union (IUCN) on the 15^thNovember, 2007. Some fishermen use improper ways to get the shark fins for retailing. They just simply use baits to attract the sharks. When the sharks come up, they just cut off their fins on their back and throw them back to the sea. However, fins help all fishes to balance and swim faster. Without fins, sharks are likely to sink and they cannot get the food they need to survive. It will be easy for them to die of starvation once their fins are being cut off. This shows that the consumption of shark fins by human beings are actually destroying the marine ecosystem.

  Actually, over-exploitation of different kinds of resources, not only over-fishing, will bring problems to the future. For example, people do not use electrical appliances wisely, they are just wasting the world energy resources. Although there are many different types of renewable energy resources like the hydro-electric power(HEP), Nuclear Power, or even Wind Power, I still think that being environmentally friendly is the most effectively way to protect the Earth.

         Few days ago, our Chief Executive, Mr. Donald Tsang wrongly used the Cultural Revolution in 1966 to describe the development of democracy in Hong Kong. After his utterances, many people criticized him about his ignorance to Chinese history. Mr. Tsang only apologized in writing without coming out to explain the situation. One question was raised from the society, ow much do the government know about Chinese history??

Actually, The Cultural Revolution in the People's Republic of China was a struggle for power within the Communist Party of China that manifested into wide-scale social, political, and economic chaos, which grew to include large sections of Chinese society and eventually brought the entire country to the brink of civil war. This is totally different from the current situation as what Hong Kong people ask for is democracy in form of universal suffrage. We are not aim at overthrowing the existing government and no sanguinary event has happened because of this. How can the government say that we are starting another ultural Revolution? Does it mean that the government think that democracy equals to revoltion or the government knows nothing about our Chinese history?

Being a Chinese, we should learn about our country history. Learning Chinese history can help ue to know about the bittering history of China in the past. They suffered from forgien attacks and many people has contributed to today success. China transformed from a backward, feudalist contry into a modern country with strong army, technology and even astronomy in these days. I believe that many people experienced hardship and paid much effort in the process of modernization in the country. We should not forget what they have done for China. Besides, being a Chinese national, we should learn from the past and respect heroes like Mao Zedong, Deng Xiaoping and Zho Enlai. They paid much effort in leading and transforming the country. We should know what they have done for China. That why, we should learn about Chinese history like some atriotic?students who study Chinese history in our class.

People tend to have babies when they are young, or I should say too young. Some girls even give birth to their children when they are 18 or even smaller. Although the Hong Kong Government encouraged people to have more babies last year, I think this should not happen on youngsters.

According to the research conducted by the government before, there is a sharp increase in child abuse in these years. A couple of days before, a pair of lovers of 16-year-old has had a baby. The girl gave birth to the baby and threw him away to a refuse station. They claimed that they found a baby but the police investigated and found out the truth. This taught us an important lesson that if we are unable to make a suitable choice at the beginning, we should think twice before we act. If we know that we cannot give our children a good and well-planned future, should we do something to avoid this?

Many young lovers only concern about their own needs and wants without considering others. For example, they just have sex whenever they want. They do not consider about problems that may arouse from doing that. What will they do if the girls get pregnant? Just simply kill him or give birth to him?

In my opinion, families and school authorities play two important roles in teaching youngsters. Family members, especially parents, can spend more time on understanding their students. Sometimes, parents claim that they know nothing about their children. However, do they ever think about how much time they have given to their children? Children may want to talk to their parents but most parents are busy with work. They cannot afford to spend much time on their children and this give rises to different kinds of problems. This also suggests the importance of communication between family members.

The school authorities can monitor students?behaviour and organize some talks for them. They are youngsters and they need to be educated by others. Talks can help them to understand how difficult will they be if they did something wrong. However, I think that the most important thing is that teenagers should be responsible for what they have done.
