8.A lot of us think that we should visit the dentist every six months.Whether those check-ups are really necessary is,however,a matter of debate.In 2000,three-quarters of dentists surveyed in New York were recommending six-monthly check-ups,despite the absence of evidence.Today,many organizations still recommend six-monthly check-ups.But for several decades some have been arguing that the choice of six months as the ideal space between visits is rather questionable.For example,Aubrey Sheiham,a professor of dental public health,published a paper complaining about the lack of evidence for six-monthly check-ups.Almost 40years,he's still making the same point.Last year the Cochrane Collaboration performed a review of the research that had been done and they were disappointed with what they found.The quality and quantity of the research was simply too poor to back up the idea of six-monthly check-ups.
There's something else we have to bear in mind.Even when a study finds,for example,that children who go to the dentist frequently have fewer fillings,there may be other factors(因素) at work.Those same children may have other advantages; they may eat more healthily and have better quality dental equipment.
How often should you visit the dentist,then?Bodies like Nice,which provides guidance for the National Health Service in England and Wales,say that the frequency of dental visits all depends on the individual.They recommend that children go at least once a year because their teeth can decay(蛀蚀) faster,while adults without problems can wait as long as two years.They even go as far as to say that longer than two years is OK for people who have shown commitment to caring for their teeth.
Where does this leave the rest of us the next time we receive a card in the mail reminding us our next dental visit is due?We'd all like an excuse to go less often,and the good news is that if you don't have any problems you can probably wait a little longer than six months between visits.But exactly how long you can wait before your appointment with the dentist's chair will depend on the assessment you and your dentist make of your own risk.

分析 本文是一篇议论文.很多牙医和护牙组织都认为,我们应该每六个月去检查一次牙.但是经过许多研究,并没有找到可以支持这种观点的合理性的确切证据.因此作者认为,我们长时间去看一次牙医可以取决于个人的实际情况.
解答 63.B 64.C 65.B 66.D
63.B 细节理解题.根据文章第一段第四句Today,many organizations still recommend six-monthly check-ups.可知,现在有很多组织偶读建议人们每六个月就去做一次牙齿检查.
64.C 细节理解题.根据第三种第二句 there may be other factors(因素) at work.可知,这项研究可能无法证实人们每六个月去做一次牙齿检查的这种观点是因为:可能有其他一些因素起作用.
65.B 推理判断题.根据最后两段和第四段中的第二句hat the frequency of dental visits all depends on the individual可知,多长时间去看一次牙医取决于个人情况,即看牙医的频率因人而异.
66.D 标题归纳题.根据文章内容可知,本文主要讨论的是人们应该多久去做一次牙齿检查.
点评 做阅读时经常犯错的主要原因是,仅凭读过文章后残留在脑海中的一丝印象来勾选答案,这样便很容易掉入出题人故意设布下的题目陷阱.所谓阅读理解,对于题目的理解一定要忠实于原文,因此,每一道题都应该与原文作全面的对比与核查,再得出答案.也就是说,阅读理解的每一道题目,在原文都应该有明确的出处,我们把这一出处叫做原文相关句,(1)排除与原文相关句主题不一致的选项(2)排除与原文相关句态度相反的选项 (3)排除用于过于极端或负面的选项(4)注意结合文章主旨和主题去排除.
