9．The world moves so quickly nowadays．With so many daily responsibilities，some of us can hardly keep our heads above water．Should we make time for studying  or appreciating the arts？Many people would say the arts are nice，but not necessary．In school，students should focus on languages，math and science．Painting，drama and music are frills． After graduation，listening to Mozart won't lead you to a better-paying job．
     In truth，spending time learning to appreciate the arts may be more worthwhile than you think．A recent British study examined the salaries and jobs of people who spent time enjoying the arts when growing up．The researchers found those who enjoyed the arts from an early age had better jobs and higher salaries than those who didn't．What's the link？How could visiting a museum，enjoying a symphony，or honing painting skills lead to career success？It turns out that the arts help us develop many useful skills．
      Other students have found students studying the arts exercise their reasoning ability．The skill helps with problem-solving．Creative and critical-thinking abilities are also developed through art study．Moreover，those who enjoy the arts have more motivation（动机）to achieve．Students who practice an art experience the rewards that come from persistence and goal-setting．These benefits also extend to those who make time to appreciate the arts beyond their school years．The best kind of art stirs our imagination and makes us think．Paintings aren't just pretty pictures．They tell stories about the lives of the subjects or about the experience of the painter．See Michelangelo's art and you'll taste the power of his faith in God．Look at the world from Picasso's point of view，and you see everyday life in new ways．Those who appreciate the arts also gain a broader perspective on the world．The arts reveal and explain the world beyond our own personal knowledge which can help us better communicate and cooperate with other people．
      If you want to better yourself，go and enjoy the arts．Check out an art gallery or a museum．Take in a play．You won't regret it and it will do you more good than you can imagine．

8．As the population of the planet increases，so does the number of homes，business，parking lots，schools，airports and roadways．All these structures use electricity and need to be lighted．Humans demand light．They want their homes more comfortable and they want their streets safe．The problem is that researchers are finding that all the light is having a negative effect on humans and wildlife as well．
Less than 10years ago I drove to a thinly populated section of my own，lay down in the middle of the road and watched an attractive meteor shower（流星雨）．If I did that today，I wouldn't be able to see the meteor shower．
Nowadays scientists are finding light pollution can be almost as bad as carbon dioxide （二氧化碳）pollution．One of the saddest parts of light pollution is that most of it is unnecessary and most of the outdoor light that we use is wasted．One only needs to look at a row of street lights to see how much of the lights shines upwards and lights the sky：a total waste of electricity．
Additionally，the production of electricity creates pollution by releasing greenhouse gases．This affects the air we breathe and our quality of life．
Scientists are also studying the effects of light pollution on wildlife．Thousands of birds die each year when they crash into highly lighted buildings，as they become puzzled by the light．It has been long known that tiny baby sea turtles become lost and follow the light on the shore instead of heading towards the sea．
Fortunately，light pollution is one of the easiest sources of pollution that can be corrected without a negative effect．Following some guidelines and a little searching on Google can give you many ideas on how to reduce your contribution to light pollution．
