第1题：
People have smoked cigarettes for a long time now. The tobacco which is used to make cigarettes was first grown in what is now part of the United States. Christopher Columbus, who discovered America, saw the Indians smoking. Soon the dried leaves were transported to Europe. In the late 1800s, the Turks made cigarettes popular.
Cigarette smoke contains at least two harmful substances, tar and nicotine. Tar, which forms as the tobacco bums, damages the lungs and therefore affects breathing. Nicotine, which is found in the leaves, causes the heart to beat faster and increases the breathing rate. Nicotine in large can kill a person by stopping a person′s breathing muscles. Smokers usually take in small amounts that the body can quickly break down.
Nicotine can make new smokers feel dizzy (头晕) or sick to their stomachs. The heart rate for young smokers increases 2 to 3 beats per minute. Nicotine also lowers skin temperature and reduces blood flow in the legs and feet. It plays an important role in increasing smokers′ risk of heart disease and stroke.
Smoking cigarettes is dangerous. Cigarette smoking was the cause of lung cancer and several other deadly diseases.
Tobacco first appeared in ___________.A.Asia
B.Africa
C.Europe
D.America答案：D解析：细节题。根据第一段第二句话“The tobacco which is used to make cigarettes was first grown in what is now part of the United States．”可知答案为D。 -

本题为主旨题。全文主要讲述的是长期坐着的坏处，呼吁大家站起来运动，文章第一段说每天坐着的时间不超过三个小时可以多活两年。A项符合题意。文章虽然提到了锻炼的好处以及看电视的坏处，但是中心不是这两个，因此B、C项可以排除。D项“永远不要坐下”太绝对了，作者并没有这种意思，因此可以排除。 -

DIt must still be necessary to restrict smoking after several generations.
正确答案： B解析：
事实细节题。文章末尾一段第五句意思是也许国家或市政府可以尝试将禁令的有效范围扩展到家中，所以B正确。第三、四句意思是，为什么不尝试一些更严厉的禁烟令?有些地区已经限制和孩子在一起的父母在车内抽烟，但是还未看到评估这些措施的报告。这显示出作者希望尝试一些更为严厉的禁烟令，所以A错误。第七句谈到，我们可能会决定在某种程度上抽烟是否仍是个人选择，所以C错误。本段最后一句指出因为没有吸烟者，可能在几代人之后不需要禁烟了，所以D也是错误的。正确答案为B。 -

CChristian Jarrett found the morbid signs on cigarettes play an important role for all smokers.
DThe measure that parents are restricted from smoking in cars with children is useful
正确答案： D解析：
推理判断题。第一段开头提到，市政府在餐馆和酒吧的禁烟令虽然极具争议，但是历史表明它们非常有效。所以A正确。第三段中提到，Scribbler50的贴激发了博客名为PalMD的医师对禁烟的有效性进行调查的灵感。由此可见，B错误，是PalMD进行的调查。第六段中提到不是所有反对吸烟的标语都同等有效，而要看针对谁，有时候可能会适得其反，所以C不准确。最后一段中提到，一些地区已经限制和孩子在一起的父母在车内抽烟，但还没有看见有关评估这些结果的报告，所以D错误。正确答案为A。 -
