第37题: [多项选择]Is environment protection important Why
参考答案:Suggested answers:
a.I think environment protection is very important. Corporations, and especially manufactures, are in business to provide products and services that enrich people’s lives, making them happier and more convenient. At the same time, these products must be environmentally conscious, both in terms of manufacturing and marketing, to ensure that the environmental burden is reduced and the products contribute tribute to the goal of establishing an environmentally and economically sustainable society. Without environment protection, there will be no sustainable development.
b.As we all know, environment protection is necessary. The air, water, and the land on Earth are being harmed by man’s activities. We believe that just as advances in technology and the establishment of social systems helped resolve local pollution problems, technology can also answer these global environmental threats. However, it is imperative for the government of the countries around world to legislate on the environment protection.
c.Environment protection is important. Many companies have started to respond the universal call of conversation by developing and applying various environmentally friendly technologies in the production since AII0. The pollution includes carbon dioxide and heat emissions, discharges of hazardous chemical substances into the atmosphere or waterways and other waster produced.
d.Environment protection is necessary. In terms of energy conversation, many companies are able to ensure that A00 per cent of its new products consumed less energy during operation than the previous models. In particular, the on-demand energy-efficient technologies incorporated into its copying machines and laser beam printers have resulted in a cumulative reduction in carbon dioxide emissions. At production sites, in terms of energy conservation, the basic unit of carbon dioxide from production declined CH per cent compared with AII0.
e.Environment protection is important. Many companies are now spending lots of resources in developing new environmental technologies and ecological components such as lead-free lenses, excellent chromium-free screws, solar cells, plastic recycling and high-performance Eco-Polymer, to name just a few. All these technologies not only help protect the environment but also help increase users’ work and cost efficiency.
f.We should pay great attention to environment protection. Products and technologies can become outmoded as quickly as they once appeared. Rather like a mayfly, the life span of most products is disturbingly brief and a good number of the current products featured in this book will, by the time of it is published, already be redundant or replaced by newer, brighter versions, with even more potential to perform and please.
g.Recycling is important to help protect our environment. Little can be bought without the disposal of something else; this is the reality of modem consumption. The new and shinny arrives while the old is rejected both physically and psychologically. Years of ignoring the environmental problem of the disposal of goods have led to an acute situation in China as elsewhere. Re-use can be a way of delaying the burial or cremation of a ’dead’ product and there is a thriving industry in developed countries of exporting used cars and of the repair, re-sale and export of used telephones, video players and televisions to developing nations. The main difficulty associated with this type of re-use economy is that it really only defers the ultimate disposal of the product, and to a country that may be without regulated disposal system.
h.Environment protection is important. Some people vigorously protested lack of control over automobile exhaust fumes, industrial smoke, unhealthy open dumps, untreated sewage, and chemical wastes that were being thrown into lakes and rivers. The agency was created to control and abate pollution in the basic areas of air, water, solid waste, pesticides, noise, and radiation. The government offers incentives to encourage cleanup efforts, and law enforcement when necessary to curb pollution.
i.The Chinese government pays great attention to environment protection. The environment protection agency conducts extensive research, provides technical assistance to provinces and cities, determines tolerable limits of pollution, and establishes timetables to bring polluters into line with standards. Since most of the requirements are of recent origin, industries are given reasonable time, often several years, to conform to standards. Monitoring data show a nationwide decline in at least two air pollutants—carbon monoxide and sulphur oxides. Current auto emission controls resulted in a reduction of carbon monoxide and hydrocarbons of nearly HE percent over cars made before B00H. The agency of environment protection also enforces noise standards for trucks and airplanes.
j.People here demand everything to be quick and convenient—to change their lifestyle and fast-food culture is difficult. That’s why I think we should start with education so that the next generation can develop an environment-friendly lifestyle. Youngsters need to learn about sustainable development. Environment protection is a must in education.
