1环境污染From the picture above, we can see that people are coughing in the polluted air. With air pollution worsening than before, pm 2.5 has become a usual word for us. Needless to say, people do not like this word, as the content the word represents does great harm to people's health.As the polluted air does affect our health, we should take some measures to make the air cleaner. On the one hand, we should take mass transit （公共交通）instead of driving a car. According to a recent study, vehicle exhaust （汽车废气）is a main source of air pollution, so if vehicle exhaust reduces, the air will become cleaner. On the other hand, more trees should be planted to absorb the tiny dust in the air, which surely will make the air cleaner.Protection of the environment needs constant efforts by every people on the planete Only in this way can we have cleaner air and more livable environment.2改编名著Adaptation Should Not Go Too Far From the ClassicsIn recent years, many classics, especially the Four Great Classical Novels, have been adapted in improper ways. For examples, in a TV series adapted from Journey to the West, Monkey King ridiculously falls in love with an evil spirit （妖精）. It has gone too far from the original version in which the upright Monkey shows no mercy to ant evil spirit.Various reasons account for this phenomenon. Firstly, readers' or audiences1 preference plays a critical role. In this market economy, where there is demand, there is supply. So many play writers or directors cater for （迎合）these people's need. Secondly, some producers want to attract people and make profit.To curb this phenomenon, I think two measures should be taken. First, it's necessary to change the way people treat classics. An adapted version that goes too far from the original one is not merely disrespect to the author; but also misleads the readers or the audiences. Second, the concerned authority should check and ban TV series, videos or books that spoof （愚弄） classics.3手机控Addiction to SmartphonesDo you check your smartphone frequently? Do you feel distracted if your smartphone is not with you? When there's no wifi or signal for your smartphone, will you get irritated 生气？If you say yes, then you've got addiction to smartphones.Smartphone addiction is a phenomenon that causes a lot of troubles to people.In the first place, it may cause some problems to your health, such as visual fatigue 视觉疲劳,cervical spondylosis 颈椎疾病,and even neurasthenia 神经衰弱.A friend of mine suffers from a serious spine collapse 脊柱损坏due to her addiction to smartphones during pregnancy-Secondly, if you keep playing with your phone when you are with your friends or family, you will spend less time talking to them. In fact, it is they who need and deserve to be cared for.Lastly, an excessive reliance on smartphones may weaken your interpersonal skills. When you cannot find a place, you consult your GPS instead of consulting local people. You spare more time playing mobile games than playing real games with real people. As time passes, it's possible that you may have difficulty in communicating with people.Therefore, isn't it better to get rid of smartphone addiction?4传统文化消失On the Losing of Traditional CultureIt is widely noted that lots of traditional culture is disappearing along with the development of technology Many ancient architectures 古老建筑and traditional ways of living have been deserted.废弃It seems that the traditional culture and craftmanship will be replaced in this modem era.The following reasons can account for the above phenomenon. Firstly, traditional technologies are always considered ineffective while the new sciences are always highly efficient. Secondly/ it is costly to protect the traditional culture.The fund used to protect the ancient culture was instead delivered to the poor, it will be helpful to the improvement of their living standard. Thirdly, modern science and technology facilitate 促进both our daily and academic life a tot. For instance, college students always collect their thesis materials 论文材料by surfing the Internet instead of borrowing books from the library>In my opinion, although traditional culture is an ancient heritage, it couldn't keep pace with the development of society. It is the tide of history that 历史潮流the traditional culture and technology will no doubt be eliminated in the end.5社交网站Social Network SitesIn recent years, social network sites like Renren and Kaixin have rapidly gained popularity among all kinds of people. Many people spend a lot of time on those sites chatting, making friends and playing games- Those sites have become a part of their life.The public hold different views on this phenomenon. Some are in favor of 支those sites for they provide many opportunities to know other people and to know what's happening in the world. Besides, they're very convenient to access. One can use a computer or cell phone to log on 登录注册at home, in a restaurant, or even in the subway. But some people don't approve of 支持the social network sites. They say that people are wasting too much time on the sites. Some even get addicted to them and abandon their real life> After all, they don*t live in the virtual world.In my opinion, the social network sites can be very helpful when we want to keep in touch with friends, but we must remember that the real world is the most important in our life.6低碳生活Nowadays, there are a considerable number of individuals who prefer to lead a low-carbon lifestyle which find expression in 表土见1 the fact that more and more commuters are using public transportation system in their daily life.Low carbon lifestyle can endow 赋予us and our society with numerous 许多的benefits. Firstly, it goes beyond doubt 毫无疑问that low carbon lifestyle contributes a lot to the environmental protection and it is a favorable way to slow down the rate of climate change of our earth, which also means a lot to our health.We are supposed toundertake the responsibility to lead a low-carbon lifestyle, which is of great significance. And there is a diversity 差异of measures we can take so as to lead such an environmental-friendly life. For one thing, we are expected to minimize the use of private cars, which emit a large amount of greenhouse gases. For another, we are supposed to cultivate the public awareness of energy conservation 能源保护for energy in the world today is decreasing rapidly. For instance, we can turn off electrical appliances if not necessary as well as using renewable materials. Furthermore, at our leisure, we can seek opportunities to plant more trees which can absorb carbon-dioxide.In brief, low-carbon lifestyle is nothing but the best choice for us and only in this way can we form a harmonious relationship with the environment.7生活目标Live with a GoalAccording to the French writer Alexander Dumas, living without an aim is like sailing without a compass. It signifies that without a goal, one would live a passive life, just like the dead water in a muddy lake.Frankly speaking, to live with a goal is of tremendous significance to one's life. For one thing, a proper aim helps foster the realization of the visions, as people are better motivated when they want to attain the goal they set for themselves and have a sense of fulfillment when they succeed. For another, by setting goals one could takegood control of his/her life, without wasting time or energy being confused about what to do. With a clear direction and certain plans, one will readily get what he/she wants.Consequently, we could draw the conclusion that we should live with a target, as a goal—oriented life 有方向的生活is an active way of living. Without a clear purpose, we might feel at sea, squandering 挥霍our time and opportunities.8My Opinion on Micro-blogWith the improvement of micro-blog services and the influence of some "star bloggers”, most of whom are celebrities, micro-blog is becoming an important way for people to express themselves and communicate with others. Now, more and more people start to use micro-blog services.However, micro-blog might give rise to 引起some problems as well. Some bloggers would express their thoughts and ideas by writing them down in the micro-blogs rather than communicate with their friends or family members. Day by day, blogs tend to draw people away from real life. What's worse, lack of face-to-face communication with others might isolate bloggers from the society, which would do harm to their mental health.In my view, micro-blog is a good platform for people to show their personal experiences and communicate with others. However, micro-bloggers should adjust the item and avoid spending the whole day on blogging. After all, sitting in front of the cold screen of computer for long does no good to their health, physically and mentally.9Don't Rely Too Much on ComputersDo we rely too much on computers? Yes, we do. Almost everything w。
