Smoking is Harmful It has been estimated that smokers have made up half of the population in China.And the smokers are becoming younger and younger,even ineluding some middle school students.
Nowadays more and more people have realized smoking can do harm to people'shealth.However,some people still enjoy smoking.Why?Because some of them think it is a kind of fashion,some think it is of GREat fun and others,think that smoking can refresh themselves.
In fact,smoking is a bad habit.It can cause a lot of diseases.Meanwhile smoking is a waste of money.Besides,careless smokers may cause dangerous fires.Smoking is harmful and it is not only bad for smokers themselves,but also bad for non-smokers.Therefore,I hope all the smokers can give up smoking for themselves and also for the people around them.

明白?

两个相互接触的物体彼此进入对方的现象叫扩散，一个人吸烟，其余人闻到烟味就是因为烟分子扩散到空气中；
声音在固体中传声快，在气体中传声慢；
物体保持原来运动状态不变的性质叫惯性，乘务人员要求乘客系好安全带就是为了防止急刹车时人由于惯性要保持原来向前的运动状态而向前摔倒；
车外空气流速大，压强小，小于车内的气体压强，所以烟会向外飘．
故答案为：扩散；小于；惯性；车外空气流速较大，气体压强比较小．

1，为了您和他人的健康请不要在场内吸烟。2，方便大家再次阅读，请保持书面整洁。3，为了你我他，安全靠大家。

please don't litter around,don't smoke,don't trample grass,don't feed animals,don't climb trees!please keep quiet and abide the guide.

解题思路：根据分子的基本特征：分子质量和体积都很小；分子之间有间隔；分子是在不断运动的；同种物质的分子性质相同，不同物质的分子性质不同，结合事实进行分析判断即可．

非吸烟者往往会因吸烟者吸烟而造成被动吸烟，是因为烟气中含有的烟气分子是在不断的运动的，烟气分子向四周扩散，造成人们被动吸烟．
故选D．

点评：
本题考点： 利用分子与原子的性质分析和解决问题．

考点点评： 本题难度不大，掌握分子的基本性质及利用分子的基本性质分析和解决问题的方法是解答此类题的关键．

无烟区必须用东西完全隔开，哪怕是一堵玻璃墙。如果单纯的在一个大厅里建立一个无烟区，那等于没建立，而且加大了限制顾客的难度

烟头是火源,被子是可燃物
燃烧条件可进一步叙述为：
（1） 具备一定数量的可燃物；
（2） 有足够数量的氧化剂
（3） 具备一定数量的点火源.
这三个条件要同时具备,相互作用,燃烧才会发生.

翻译如下：
We are not supposed to smoke in the classroom
It is the golden rule that to maintain the freshness of friendship is to trust each other.

Dear friend,
How are you?
Are you still
smoking? If so, I would like to suggest you to quit smoking. Here are some
reasons supporting my suggestion.
1. For your health! According to the Surgeon General,
quitting smoking is the single most important step a smoker can take to improve
the length and quality of her or her life. As soon as you quit, your body
begins to repair the damage caused by smoking. Of course it's best to quit
early in life but even someone who quits later in life will improve their health.
2. To save money! It's getting more expensive to smoke
cigarettes. A pack of cigarettes can averagely cost ￥10.00 to ￥20. Even if
a pack costs "only" ￥5.00 where you live, smoking one pack per day adds up to $1,825.00
each year.
3. To save the aggravation! It's getting less convenient to
smoke. More and more states and cities are passing clean indoor air laws
that make it illegal to smoke in bars, restaurants, and other public places.
Are you tired of having to go outside many times a day to have a cigarette? Is
standing in the cold and the rain really worth having that cigarette? Wouldn't
it be easier if you had the choice to go outside only when you want to and not
when you need to?
4. It's good for the people around you! Cigarette smoke is
harmful to everyone who inhales it, not just the smoker. Whether you're young
or old and in good health or bad, secondhand smoke is dangerous and
can make you sick. Children who live with smokers get more chest colds and ear
infections while babies born to mothers who smoke have an increased risk of
premature delivery, low birth weight and sudden infant death syndrome (SIDS).
Hope you quit smoke as soon as possible.
Best wishes
Sincerely yours,
Mike

A、烟草在燃烧过程中，产生了许多有害物质，如尼古丁、一氧化碳、烟焦油等，吸烟有害健康，故选项说法错误．
B、葡萄糖是含碳的化合物，是一种有机物，是人体内重要的提供能量的物质，故选项说法正确．

D、甲醛有毒，能破坏人体蛋白质的结构，使蛋白质变性，食用甲醛浸泡的食物对人体有害，故选项说法正确．
故选A．

解题思路：此题考查的知识点是吸烟的危害．解答时可以从吸烟对呼吸系统、对他人的危害、长期吸烟的危害方面来分析．

吸烟时产生烟雾里有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．这些有毒物质严重危害人的呼吸系统和其它系统，更为严重的是，吸烟者还严重妨碍他人健康．研究结果表明，吸烟者吸烟时对旁人的危害比对他自己还大．长期吸烟或被动吸烟，易导致肺炎、气管炎、肺癌等疾病．
由上可知，小倩的爸爸吸烟，小倩和妈妈虽然不吸烟，但是被动吸烟者，烟雾中的尼古丁等有毒物质，抑制了气管、支气管内表面纤毛的摆动，使痰不能及时排出，使呼吸道易受到病菌的侵袭．因此小倩经常咳嗽、患气管炎等疾病．
故答案为：被动；纤毛；痰

点评：
本题考点： 吸烟对人体健康的危害．

考点点评： 解答此类题目的关键是理解吸烟和被动吸烟的危害，并了解痰的排出受纤毛的影响．

吸烟首先危害呼吸系统，易患哮喘等慢性呼吸系统疾病，有关医学研究表明，吸烟是心脑血管疾病、癌症、慢性阻塞性肺病等多种疾患的行为危害因素，吸烟已成为继高血压之后的第二号全球杀手．更为严重的是，吸烟造成的烟雾会造成严重的环境污染，严重妨碍他人健康，吸烟者吸烟时对旁人的危害比对他自己还大．有关医学研究表明，吸烟是高血压、冠心病等心脑血管疾病、癌症、慢性阻塞性肺病等多种疾患的重要危害因素，吸烟已成为继高血压之后的第二号全球杀手．长期吸烟者的肺癌发病率比不吸烟者高10倍至20倍，喉癌发病率高6至10倍，冠心病发病率高2至3倍，循环系统发病率高3倍，气管类发病率高2至8倍．被动吸烟的危害更大，每天平均1小时的被动吸烟就足以破坏动脉血管．一些与吸烟者共同生活的女性，患肺癌和子宫癌的几率比常人多出6倍．可见D符合题意．
故选：D

首先,求样本总人数B样本一共126人,占42%,所以样本总人数就是126÷42%=300人
然后,持无所谓态度的,占样本总人数的百分比12÷300=4%
最后估算无所谓态度的人数 140000×4%=5600人
建议,加强宣传力度,让他们明确吸烟有害健康,经常吸烟害人害己,提倡他们戒烟
