答案解析

细节题。题目问的是：当你患感冒的时候，会怎么样?用题干信息词：When，having a cold回归原文，定位到原文第三段：There are more than 150 different cold viruses，and you never have the same one twice．Being infected by one makes you immune to it—but only it．对比分析原文和题目，原文提到有150多种感冒病毒，而人们绝不会被同一种病毒侵害两次，因为得了一次感冒后对相应的病毒就获得了免疫力，所以只有C项才符合第三段的内容。所以答案为C。

Cigars Instead?

Smoking one or two cigars a day doubles the risk of cancers of the lip, tongue, mouth, and throat,according to a government study"
Daily cigars also increase the risk of lung cancer and cancer of the esophagus, and increase the risk of cancer of the larynx (voice-box) six-fold, say researchers at the National Cancer Institute in Bethesda, Maryland.
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 cancer by four times the risk of nonsmokers.
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 tobacco-specific nitrosamines.
"This article provides clear and invaluable information about the disturbing increase in cigar use and the significant public health consequences for the country," said Dr. Richard Klausner,director of the National Cancer Institute, in a statement.
"The data are clear -- the harmful substances and carcinogens in cigar smoke, like cigarettes,are associated with the increased risks of several kinds of cancers as well as heart and lung diseases," he added. "In other words, cigars are not safe alternatives to cigarettes and may be addictive."
"To those individuals who may be thinking about smoking cigars, our advice is -- don't. To those currently smoking cigars, quitting is the only way to eliminate completely the cancer, heart and lung disease risks," warned Klausner.
According to National Cancer Institute press release, there haven't been any studies on the health effects on nonsmokers at cigar social events, but "...a significant body of evidence clearly demonstrates an increased lung cancer risk from secondhand smoke."
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.
