New Technology Is One Way to Solve Noise Pollution
There have been an increasing number of complaints and lawsuits about noise pollution in some major world cities. The problem with noise is not only that it is unwanted, but also that it negatively affects human health and well-being. In my opinion, the government should attach importance to the research and application of technology in order to reduce noise pollution.
First, the application of sound-absorbing or sound-insulation material shows the quickest sign of the reduction of noise pollution. Noise inside a building can be reduced if both the external and internal walls are made of sound deadening materials. Heavy and dense materials such as masonry or brick walls are better for sound reduction. The application of sound reduction materials is economically and technically feasible in dealing with four main noise sources, namely transportation, industrial production, construction, and social activities. Furthermore, the introduction of hybrid cars has made advances in the reduction of motor vehicle noise. Noise from transportation is one major source of noise pollution. The application of cars with low level noise will be effective in reducing noise emission.
In conclusion, with people exposed to dangerous sound levels on the rise, noise pollution has become a common occupational and environmental hazard. I strongly recommend that the government should spare no efforts in funding and investing in new technologies which will be essential in noise pollution reduction. (227 words)
Everyone may encounter a scene when he or she wonders what the meaning and purpose of life is. Answers to this question vary from person to person. As for me, I agree with the view that the meaning of life is to discover your gift and the purpose of life is to make the best of it.
On one hand, one's gift could be the source of his inner happiness, providing spiritual impetus and correct orientation. Take the world-renowned Chinese pianist Lang Lang as an example. His gift was noticed before he was 3 years old, which laid the foundation of his glorious life. On the other hand, proper use of talent helps people to realize their value in a positive way, thus making contribution to the society as a whole. For instance, Isaac Newton made a universally amazing discovery by digging into his gift and finding the Newton's law of gravitation.
In conclusion, let's search for our true gift and utilize it to the fullest to achieve a happy and valuable life.
It is not too much to say that it is a destructive behavior to allow to be controlled by bad habits while it is constructive to change unwanted habits. If bad habits are allowed to be developed, they will get out of control and become big obstacles to life or career. For example, a delayed-prone person will hardly restrain himself from missing the deadline. Understandably, he will have few chances to be entrusted with important tasks and then will barely be professionally experienced enough to gain promotion. On the contrary, it is beneficial to change unwanted habits and acquire good ones, because good habits can make people more competent and thus widen the door to success.
In summary, bad habits will probably make it impossible for us to achieve our ambitions. Therefore, we should be alert to our bad habits and make persistent efforts to break them.
