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(蛀蝕) 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 本文是一篇議論文.很多牙醫(yī)和護(hù)牙組織都認(rèn)為,我們應(yīng)該每六個(gè)月去檢查一次牙.但是經(jīng)過許多研究,并沒有找到可以支持這種觀點(diǎn)的合理性的確切證據(jù).因此作者認(rèn)為,我們長時(shí)間去看一次牙醫(yī)可以取決于個(gè)人的實(shí)際情況.
解答 63.B 64.C 65.B 66.D
63.B 細(xì)節(jié)理解題.根據(jù)文章第一段第四句Today,many organizations still recommend six-monthly check-ups.可知,現(xiàn)在有很多組織偶讀建議人們每六個(gè)月就去做一次牙齒檢查.
64.C 細(xì)節(jié)理解題.根據(jù)第三種第二句 there may be other factors(因素) at work.可知,這項(xiàng)研究可能無法證實(shí)人們每六個(gè)月去做一次牙齒檢查的這種觀點(diǎn)是因?yàn)椋嚎赡苡衅渌恍┮蛩仄鹱饔茫?br />65.B 推理判斷題.根據(jù)最后兩段和第四段中的第二句hat the frequency of dental visits all depends on the individual可知,多長時(shí)間去看一次牙醫(yī)取決于個(gè)人情況,即看牙醫(yī)的頻率因人而異.
66.D 標(biāo)題歸納題.根據(jù)文章內(nèi)容可知,本文主要討論的是人們應(yīng)該多久去做一次牙齒檢查.
點(diǎn)評(píng) 做閱讀時(shí)經(jīng)常犯錯(cuò)的主要原因是,僅憑讀過文章后殘留在腦海中的一絲印象來勾選答案,這樣便很容易掉入出題人故意設(shè)布下的題目陷阱.所謂閱讀理解,對(duì)于題目的理解一定要忠實(shí)于原文,因此,每一道題都應(yīng)該與原文作全面的對(duì)比與核查,再得出答案.也就是說,閱讀理解的每一道題目,在原文都應(yīng)該有明確的出處,我們把這一出處叫做原文相關(guān)句,(1)排除與原文相關(guān)句主題不一致的選項(xiàng)(2)排除與原文相關(guān)句態(tài)度相反的選項(xiàng) (3)排除用于過于極端或負(fù)面的選項(xiàng)(4)注意結(jié)合文章主旨和主題去排除.
