Smoking
Since 1939, numerous studies have been conducted to determine whether smoking is a health hazard. The trend of the evidence has been consistent and indicates that there is a serious health risk. Research teams have conducted studies that show beyond all reasonable doubt that tobacco smoking is associated with a shortened life expectancy1.
Cigarette smoking is believed by most research workers in this field to be an important factor in the development of cancer of the lungs and cancer of the throat and is believed to be related to cancer of some other organs of the body. Male cigarette smokers have a higher death rate from heart disease than non-smoking males. Female smokers are thought to be less affected because they do not breathe in the smoke so deeply.
Apart from statistics, it might be helpful to look at what smoking tobacco does to the human body. Smoke is a mixture of gases, vaporized chemicals, minute particles of ash and other solids. There is also nicotine, which is powerful poison, and black tar. As smoke is breathed in, all those components form deposits on the membranes of the lungs. One point of concentration is where the air tube and bronchus divides. Most lung cancer begins at this point.
Filters and low tar tobacco2 are claimed to make smoking to some extent safer, but they can only slightly reduce, not eliminate the hazards.

谜底与题解：
1.B 该题说的是：判定吸烟对安康是不是有风险是轻易的。可是，文章的第一句话是这么说的：自1939年以来，停止了很多次研讨，其目标都是为了判定吸烟对安康是不是是一种风险。能够看出判定吸烟对安康是不是是一种风险并不轻易。
2.A 该题说的是：吸烟会延长人们的预期寿命。该题源于第一段最初一个句子中的`子句：tobacco smoking is associated with a shortened life expectancy吸烟会延长人们的预期寿命。
3.A 该题说的是：吸烟有能够引发肺癌。文章的第二段和第三段都讲到了吸烟与肺癌的干系。
4.C 该题说的是：有证据申明乳腺癌是吸烟引发的。文章不说起乳腺癌与吸烟的干系。
5.B 该题说的是：男性烟民死于心脏病的比率小于女性烟民死于心脏病的比率。文章不间接比拟男性烟民和女性烟民死于心脏病的比率，但有这么一句话：Female smokers are thought to be less affected because they do not breathe in the smoke so deeply.据以为女性烟民并不把烟吸得很深，烟对她们的影响小于男性烟民。从中能够揣度出的是：男性烟民死于心脏病的比率高于女性烟民死于心脏病的比率。是以该题的命题是毛病的。
6.A 该题说的是：尼古丁是有毒的。谜底可在第三段找到。
7.B 该题说的是：有了过滤嘴和焦油含量低的烟草，吸烟是宁静的。文章的最初一段(也是最初一句)是这么说的：据称，过滤嘴和焦油含量低的烟草在某种水平上使吸烟变得较为宁静，可是它们只是稍微削减风险而不是消弭风险。是以该题的命题是毛病的。
