问答题Smoking bans in public places are becoming more and more common in China. Whether the right of the non-smoker to breathe in fresh air outweighs that of the smoker to smoke freely is a matter of opinion, manifesting itself in a heated smoking ban debate. The following are opinions from both sides on this issue. Read the excerpts carefully and write your response in about 300 words, in which you should: 1. summarize briefly the opinions from both sides, and then 2. give your comment. Marks will be awarded for content relevance, content sufficiency, organization and language quality. Failure to follow the above instructions may result in a loss of marks. A smoking ban is a public policy that includes criminal laws and health regulations that prohibit smoking in certain public places and workspaces. There are many reasons why smoking bans originated, but most of these have medical origins. Research has shown secondhand smoke is almost as harmful as smoking in and of itself. The effects of secondhand smoke are relatively the same as smoking. Lung disease, heart disease, bronchitis and asthma are common. Those who live in homes with smokers have a 20-30 percent higher risk of developing lung cancer than those who do not live with a smoker. Smoking bans are also imposed because they improve air quality in restaurants and other establishments. In Beijing, it is now illegal to smoke in all hospitality venues. Studies have also shown employees are exposed to far fewer toxins in areas where smoking is banned in the workplace. Despite the positive effects on health and air quality, many people are still opposed to smoking bans in China. Critics oppose smoking bans and see these laws as an example of the government interfering in people’s lives. They look at the effects on smokers, not those on non-smokers who are subjected to second-hand smoke. Other critics emphasize the rights of the property owner and draw distinctions between public places, such as government building and privately owned businesses, such as stores and restaurants. Some critics of smoking bans believe that outlawing smoking in the workplace may cause smokers to simply move their smoking elsewhere. Instead of smoking indoors, workers may begin smoking in public parks and exposing a new set of people to their secondhand smoke.
