Face masks may not protect from super-flu
If a super-flu strikes, face masks may not protect you. Whether widespread use of masks will help, or harm, during the next worldwide flu outbreak is a question that researchers are studying furiously. No results have come from their mask research yet. However, the government says people should consider wearing them in certain situations anyway, just in case.
But it’s a question the public keeps asking while the government are making preparations for the next flu pandemic. So the Centers for Disease Control and Prevention (CDC) came up with preliminary guidelines. “We don’t want people wearing them everywhere, ”said the CDC. “The overall recommendation really is to avoid exposure.” 来源：中国职称英语考试网
When that’s not possible, the guidelines say to consider wearing a simple surgical mask if you are in one of the three following situations. First, you’re healthy and can’t avoid going to a crowded place. Second, you’re sick and think you may have close contract with the healthy, such as a family member checking on you. Third, you live with someone who’s sick and thus might be in the early stages of infection, but still need to go out.
Influenza pandemics can strike when the easy-to-mutate flu virus shifts to a strain that people never have experienced. Scientists cannot predict when the next pandemic will arrive, although concern is rising that the Asian bird flu might trigger one if it starts spreading easily from person to person.来源：中国职称英语考试网
During the flu pandemic, you should protect yourself. Avoid crowds, and avoid close contract with the sick unless you must care for someone. Why can’t mask added to this self-protection list? Because they help trap virus-laden droplets flying through the air with a cough or sneeze. Simple surgical masks only filter the larger droplets. Besides, the CDC is afraid masks may create a false sense of security. Perhaps someone who should have stayed home would don an ill-fitting mask and hop on the subway instead.
Nor does flu only spread through the air. Say someone covers a sneeze with his or her hand, then touches a doorknob or subway pole. If you touch that spot next and then put germy hands on your nose or mouth, you’ve been exposed. It’s harder to rub your nose while wearing a mask and so your face may get pretty sweaty under masks. You reach under to wipe that sweat, and may transfer germs caught on the outside of the mask straight to the nose. These are the problems face masks may create for their users.
Whether people should or should not use face masks still remains a question. The general public has to wait patiently for the results of the mask research scientists are still doing.来源：中国职称英语考试网

标准答案：D,C,A,F 来源：中国职称英语考试网
解 析：1．D．这个段落主要讲述美国疾病控制和预防中心提出的口罩使用指导方针， 不希望公众过度使用口罩（段落第2句和第3句）， 因此D是答案。
2．C． 段落中出现了标志列举信息的词语：first, second, third, 由此判断在这些词汇所出现句子的前面一定会有综述性的话语， 因此关注短首句。 该句概括了在三种情况下可以带面罩， 因此C是答案。
提示：
如果段落中出现了列举性的结构（通常句首会出现first, second, third, finally等词）， 则这些列举性话语的前面应该出现概述性的话语， 而这个概述性话语的内容往往就直接揭示该段的主题。
3．A． mask是该段主题词， 因此A和F可能是答案。 A中的核心结构“self-protection（自我保护） list”直接在该段中出现了， 而F中的核心结构germy（带有病菌的） hands（手） and masks没有在该段出现， 也没有间接地涉及到， 因此F不是答案， 答案是A。来源：中国职称英语考试网
4．F． mask是该段主题词， 因此F可能是答案。F中的细节信息结构germy hands 也在段落中直接出现了， 由此进一步推断F很可能是答案。
1. The scientists are trying to find out if masks may or may not ___.
2. The CDC is afraid that the public may ___.

解 析：5．E. 该题可以直接借助问题句前面内容的提示直接判断答案。也利用问题句中的细节信息词scientists作为答案线索， 在文章中找到答案相关句：
（最后一段）Whether（是否） people should or should not use face masks still（仍然） remains（继续， 留下） a question（问题）. The general public （普通的民众）has to wait patiently（耐心地） for the results of the mask research（研究）scientists are still doing.
从以上的答案相关句的内容可以推断出E是答案。
6．A． 利用问题句中出现的特征词CDC作为答案线索， 在文章中查找答案相关句：
（第2段）But it’s a question the public keeps asking while the government are making preparations for the next flu pandemic. So the Centers for Disease Control and Prevention (CDC) came up with preliminary guidelines. “We don’t want（想要） people wearing them everywhere, ”said the CDC. “The overall recommendation really is to avoid exposure.”
从以上的答案相关句的内容可以推断出A是答案。来源：中国职称英语考试网
7．F．这道题可以借助问题句中语意的提示直接判断答案。该题的答案相关句仍然在最后一段：（最后一段）Whether（是否） people should or
