My Topic: In today's world of advanced science and technology, we still greatly value our artists such as musicians, painters and writers. What can arts tell us about life that science and technology cannot?

Here is my essay:

There is no doubt that arts bring a wide range of benefits for people, which sience and technology cannot bring for human being.

Science formulates and demonstrates a scientific hyphothesis by using evidences. It works based on reality; therefore, it cannot work relied on imagination and preception. As a result, science restricts individuals' ability in the form of creation. In contrast, art do not rely on evidence, then it releases the human sense of imagination. Hence, people can accelerate their inovation. Moreover, art satisfies citizens' feeling, which cannot approach by science. Scientific films of the Marvel producer can help residents enjoy great satisfaction of travelling to faranoy galaxies, for instance.

In terms of technology, it is created and developed to serve people's demands. It just only pay attention to practicality rather than abstract aspects, that leads to lack of emotion in life. Steadily, humans will lose happiness in their life. Art, by contrast, aims at touching heart rather than bringing practical applications. Therefore, it motivates individuals and creates pleasure for the life. For example, music which is ubiquious art not only reduces stress of labor after working day but also helps workers learn about harmony. According a research, art especially music can stimulate the young's brain develop. Thanks to listening to music regularly, children will be smarter than others who do not listen to music in daily routine. Art not only creates happiness for people but also strengthens the growth of young generation.

In conclusion, although science and technology are greatly developed but there are various things which just art can teach us that these sectors can not show.
