17.We've all seen them:perfectly toned famous people on late-night television telling us that we too can develop rock-hard abdominal muscles(腹。甀t's easy!Just pay﹩149.99 for the Torso Track or﹩149.75 for the Ad-Doer and watch those unwanted inches leave your waist.Americans spend tens of million of dollars on various products to firm up their fat around the waist.
And did they work?Not necessarily.Independent studies have concluded that most of these products-no matter who approved them or how expensive they are-shape your midsection no better than old-fashioned stomach crunches(仰臥起坐).Some can even cause injury-like the﹩518.99 Body Shaper-Q8SP,which left electrical burns on some researchers at the University of Wisconsin,La Crosse.Others,like the popular Ab-Doer,trpically burn less energy than a gentle walk,according to a study to be published in September by the American Council on Exercise.
The fact is that many Americans don't have the biological makeup to develop an obvious abdominal muscles.They are either unable to get the necessary muscle mass or they can't lose enough fat to make a difference.Even if the underlying muscles are well developed,and it takes to hide it is one-sixteenth of tan inch of fat.That's enough to dismiss most healthy women as well as plenty of guys who do crunches every day.
So what works best?In its new study,the exercise experts researched on the results of the popular Ab-Doer.A lengthy TV advertisement promises that just 10minutes a day performing such movements as"Body Boogies"and"Good Mornings"will"help form those muscles the fun and easy way without diets."Steven Loy,professor at California State University,Northridge,tested the promise by measuring the electrical activity produced by the abdominal muscles during three Ab-Doer movements.He and his colleagues then compared the results with those produced during traditional exercises.They determined that the muscles were no more active,and in some cases less so,when exercisers were using the Ab-Doer.
Taking a broader approach,researchers at San Diego State University compared 13abdominal exercises for their ability to develop the central abdominal muscles.They concluded,in a report published in May,that the most effective exercises kept turning the body and worked the muscles the entire time.Among the winners:the bicycle movements-so called because it looks as if you are riding a bike while lying flat on the floor-and exercises performed on the"Captain's Chair",a product typically found in gyms that helps hold the body in the air while you raise your legs up toward your chest.Researchers suggested that a varied routine of the different exercises could deliver the best results.

分析 文章主要通過(guò)一些列研究數(shù)據(jù)證明健身產(chǎn)品作用甚微的結(jié)論,由此建議讀者使用正確的塑肌方法,杜絕錯(cuò)誤的方法.
解答 63-66 CDCB
63:細(xì)節(jié)題.由最后一段第二句"They concluded,in a report published in May,that the most effective exercises…Among the winners:the bicycle movements-so called because…exercises performed on the'Captain's Chair'"可知最有效的鍛煉肌肉方法是 Captain's Chair,故正確答案為C.
64:細(xì)節(jié)題.由第三段第一句"The fact is that many Americans don't have the biological makeup to develop an obvious abdominal muscles."可知,很多美國(guó)人并不具備鍛造明顯腹肌的生理構(gòu)造,D項(xiàng)與原文描述一致,故正確答案為D.
65:文章第二段用 the University of Wisconsin 的研究結(jié)果說(shuō)明健身產(chǎn)品的效果并不好,第四段用研究數(shù)據(jù)說(shuō)明健身產(chǎn)品對(duì)鍛煉肌肉作用甚微,第五段用 San Diego State University 的研究說(shuō)明了最有效的肌肉鍛煉方法.由此總結(jié),作者主要用研究數(shù)據(jù)來(lái)說(shuō)服讀者,故正確答案為C.
66:主旨題.文章主要通過(guò)一些列研究數(shù)據(jù)證明健身產(chǎn)品作用甚微的結(jié)論,由此建議讀者使用正確的塑肌方法,杜絕錯(cuò)誤的方法,B項(xiàng)更符合文意,故正確答案為B.
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(guò)文章后殘留在腦海中的一絲印象來(lái)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(shuō),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(guò)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.
