吸烟时产生的烟雾里有40多种致癌物质，还有十多种会促进癌发展的物质，其中对人体危害最大的是尼古丁、一氧化碳焦油和多种其它金属化合物．这些有毒物质首先直接进入人体的呼吸系统，引起气管炎、支气管炎、肺炎、肺癌等呼吸系统疾病．为倡导人们珍惜生命，远离烟草．可以写出以下禁烟宣传标语：如树立良好思想，拒绝第一支烟；今天手上的烟，就是明日离歌．为了你和家人的健康请不要吸烟；无烟世界，清新一片；远离烟草，崇尚健康；燃烧的是香烟，消耗的是生命．

Not allowing smoking in public places and office building is a very good rule. I believe this for several reasons .Not only will banning smoking improve people’s health, it will also increase worker productivity and reduce conflicts.
we all know smoking is not healthy. Unfortunately, when smokers are able to smoke in public buildings, they can make other people sick . They may work with people who are allergic to smoking, for examples. In that case , the non-smokers have no choice unless they want to quit their jobs. They can only get sicker , which is unfair .Of course , banning smoking in public buildings and offices will please non-smokers. It will also improve the smokers’ health. They will have fewer opportunities to smoke, so they will smoke fewer cigarettes.
Banning smoking in office buildings can also increase worker productivity. Smokers won’t interrupt their work all the time to smoke. There will also be fewer worker absences. When smokers cut down the number of cigarettes, they will get fewer smoking related illnesses.
Finally, it is a good idea to ban smoking in public places and office buildings because a ban can reduce conflicts. Non-smokers tend to get annoyed and jealous because smokers have an excuse to take frequent breaks .The most significant conflict, however, is over whether smokers have a right to smoke in public . As we have already seen, non-smokers feel they are not always given a choice. If smoking in public is allowed , they will be forced to breathe harmful air. This may violate their rights, and non-smokers are angry with smokers because of it.
It seems clear that banning smoking n public places and office buildings is a good idea. It will reduce conflict and increase productivity. It will also benefit health of smokers and non-smokers alike. I believe that just about anything that improve our health is a good idea!

B、7916.67

纳税年度收入总额=2500×12个月+（95000-50000）=75000（元）
全年应纳税所得额=75000-2000×8个月-3500×4=45000（元）
前8个月应纳税额=（45000×30%-4250）×8/12=6166.67（元）
后4个月应纳税额=（45000×20%-3750）×4/12=1750（元）
全年应纳税额=6166.67+1750=7916.67（元）
