2. 解题:
1. According to the report, smoking three or four cigars a day
A. increases the risk of oral cancer for non-smokers
B. greatly increases the risk of oral cancer for smokers
C. increases the risk of more than one cancer for non-smokers
D. greatly increases the risk of more than one cancer for smokers
1. D。分析:利用题干中的核心结构(smoking three or four cigars)作为答案线索,这样在文章中找到答案相关句:
In addition, the report revealed that smoking three or four cigars a day increased the risk of oral cancer to 8.5 times the risk for nonsmokers and the risk of esophageal(食道的) cancer by four times the risk of nonsmokers.
被选项中出现的结构具有干扰性:A和C中的for non-smokers的含义是“对于不吸烟者”, 而B和D进行比较,D更合适。
2. In the passage how many cancers are mentioned in relation to smoking cigars daily?
A. six
B. seven
C. eight
D. nine
2. B。分析:注意备选项的特点(都是数字),在文章中查找cancers,发现在文章开头提到:
Smoking one or two cigars a day double the risk of cancers of the lip, tongue, mouth, and throat(小于最小的6种) ,于是继续找:
Daily cigars also increase the risk of lung cancer and cancer of the esophagus(食道的), and increase the risk of cancer of the larynx (喉) sixfold, say researchers at..
-fold suf.[置于数词后]表示“倍, 重”,
如:fivefold, manifold, hundredfold
并注意判断第3段中的
In addition, the report revealed that smoking three or four cigars a day increased the risk of oral cancer(“口腔癌症”是统称) to 8.5 times the risk for nonsmokers and the risk of esophageal(食道的) cancer
所以判断答案为:B。

3. 分析:利用题干中所问的文章名称作为答案线索,发现直接答案相关句:
The health effects of smoking cigars is one of eight sections of the article Cigars: health effects and trends . The researchers report that, compared with a cigarette, a large cigar emits up to 90 times as much carcinogenic (致癌物(质)的)tobacco-specific nitrosamines(亚硝胺)(揭示C错误).

.he added. “In other words, cigars are not safe alternatives to cigarettes and may be addictive” 该句揭示A是正确的。B中所提到的“香烟不容易上瘾”在原文中没有出现相关的内容。
4. What is the doctor’s advice to those cigar-smokers?
A. to give it up completely
B. to give up part of it
C. not to think about it any more

4. A. 分析:注意文章中涉及到“医生建议”的句子:

To those currently smoking cigars, quitting is the only way to eliminating completely the cancer, heart and lung disease risks, warned Klausner. (上文中提到:Dr. Richard Klauser, director of the National Cancer Institute)

5. In the context of this passage, secondhand smoke means
A. smoking bad-quality cigars
B. smoking very cheap cigars
C. being near cigar smokers when they are not smoking
D. being near cigar smokers when they are smoking
5. D。分析: 利用题干中引语的内容secondhand smoke作为答案线索(因为:该短语是新组合的短语),这样在文章中找到相关的语句:

借助该句有关结构判断D是答案。
