A ban on smoking in most public places goes into effect(效果) on Sunday in China - home to a third of the world's smokers. That means around 300 million smokers will no longer be allowed to light their cigarettes in the "enclosed public places." These include hotels, restaurants, theaters and public transport waiting rooms. The ban does not cover offices or factories.
   The campaign is aimed at controlling(控制) the number of deaths from smoking-related illnesses, running at a million a year. According to the World Health Organization, more than 3,000 people die every day in China because of smoking. Health experts also hope it will help Chinese to raise the knowledge of the dangers of smoking.
   But the new rules have been criticized because they do not include punishments(处罚) for those who choose not to obey them.Most people worry that Chinese smoking ban may have little effect.
   Business owners often hate rules that force(强迫) them to ban smoking on their restaurants, bar, cafe..., because many customers(顾客) do not like the rules and complain. Often you find people smoking at the next table while you are eating your meal or having a drink in a bar.
It appears that many Chinese people don't know the dangers of smoking. Research suggests only one in four knows the harm(害处) cigarettes or second-hand smoke can cause.
   At the same time the government makes a lot of money from the sales of cigarettes by the state-owned firms that make and sell all tobacco products throughout the country.

材料二：近年来，随着我国经济体制改革的不断深化，许多国有企业纷纷“转轨改制”。从而使得国有企业集体企业数量越来越少，相反，在大街两旁的广告牌上出现了越来越多的“新面孔”。对此，有人认为我国的公有制经济萎缩了，随着国企数量的减少，公有制的主体地位动摇了。
