"Let's face our life with a smile!" This is the saying that I value most in my life. Life always has ups and downs. When are left in pain, it is vital for us to take a positive attitude. The "positivity" effect leads to better health and a longer life because positive people will be less worried in the face of adversity and more likely to find solutions to problems they have encountered.

Firstly, by taking a positive attitude towards life, especially unfortunate happenings, one will have a better mood and life will be easier and happier. A famous story in China says that an old woman had two daughters, of whom one made a living by selling rain boots and the other by selling fans. When it was raining, the old woman worried that her first daughter could not sell any boots. When it was sunny, the old woman worried that her second daughter could make little money. So she worried all day and finally died of hypochondria. The story has a sad ending. However, if the old woman had been positive and thought in the opposite way, she would not have died that way. Instead, she would have lived a happy life. The story shows that one can be much happier and life can turn out to be much better if one can take a positive attitude. The "positivity" effect leads to emotional health, which is as important as physical health. Moreover, without emotional health, people can hardly gain physical health. They will easily feel worried and stressed. Once people become positive towards life, they are most likely to have better health and thus, a longer life.

Secondly, it is easier for a person with a positive attitude to remain calm and find out ways to solve the problem. In most cases, we can not be truly relaxed unless the problem is solved from root. However, if we always take a negative attitude, we will always feel depressed and stay in a panic. Thus, our mind will never be clear and we will never be able to find a solution to the problem. In addition, the situation can be worse. We may even lose our mind and lose control of ourselves, which may result in greater pain. So, it is significant to be positive in order to solve the problem. Once we have solved the problem, the stress will be taken off our hearts and we will feel much better, which will lead to better health and a longer life.

In conclusion, a positive attitude helps us to be happier and we are also more likely to find good solutions to our problems. Then we can have better health both emotionally and physically and lead to a better life. Life is like a mirror. If we give it a smile, it will give us a smile!

"Green" is often used for a person who cares a lot about our environment. Compared to a person who is not green, a green person is definitely more concerned about consumption. In daily life, a green person will seldom use plastic bags as they can not be easily recycled and reused. However, ungreen people usually prefer plastic bags for convenience. They may even throw away plastic bags that are used only once. When in restaurant, a green person is most likely to order no more than he or she can have. In case some food remains, the remaining food is often taken home. For the ungreen, when much food is left over, they never feel ashamed and instead, think it is OK as long as they have payed for the food. In addition, green people take a more positive attitude towards searching for new ways to save resources and energy. Zero-waste scheme and development of new energy are both good examples of how we can reduce consumption of natural resources. In contrast, an ungreen person never bothers himself with these questions and just leave them to others, or maybe to our future generations. Everybody wants a green and nice world, but if we are not green ourselves, how can we make our world green? We should realize that everybody should take the responsibility to save our world and then, the green world is just around the corner.

Environmental Problem

Air pollution has become one of the most serious problems in China. With higher living standard, an increasing number of people are able to have their own cars. However, the exhaust produced by these cars is a big threat to the environment as it contains not only green house gases but also toxic gases such as sulfur dioxide. In addition, China's economy depends heavily on heavy industry and many factories simply release waste gases that have not been dealt with properly. More often than not, chemicals contained in the gases will do great harm to both human beings and other living things. In the past few years, there have been quite a few cases in which industrial waste leads to diseases and deaths. Moreover, due to deforestation, China's largest "air cleaner" has got into trouble. With much fewer trees, less carbon dioxide is "replaced" with fresh oxygen. All these factors contribute to air pollution. Before the problem becomes too big to handle, measures must be taken to reduce air pollution. For our government, strict laws and policies must carried out against releasing industrial waste directly. Forests must be protected and a certain number of trees must be planted every year. For individuals, using public transport should be encouraged. People should be aware of the present situation of air quality in China and know what they can do to improve the situation. In a word, we must unit together and solve air pollution problem for the benefit of, in fact, ourselves.
