1.How many times did you brush your teeth yesterday?

3.How often do you think about fighting germs?
Finding:Seniors are not fighting germs as well as they should.

分析 本文是關(guān)于健康習(xí)慣的調(diào)查.在一天刷幾次牙,洗手沐浴幾次,以及多久考慮過和細(xì)菌戰(zhàn)斗一次等方面,描述了一些美國老年人的習(xí)慣并給出了專家建議.
解答 21.D.細(xì)節(jié)理解題.根據(jù)"A full 33% ofseniors brush their teeth only once a day."可知大約三分之一的美國老年人一天只刷一次牙,故選D.
22.D.細(xì)節(jié)理解題.根據(jù)"And nearly 30%wash their hands only 4 times a day----half of the number doctors recommend."一天洗4次手是專家建議的一半,可知專家建議每天洗8次手.故答案選D.
23.C.細(xì)節(jié)理解題.根據(jù)"Do you know it isnot your toilet but your kitchen sponge(海綿)that cancarry more germs than anything else?"可知廚房里的海綿比任何其他東西(包括廁所)攜帶的細(xì)菌都多.所以C是正確的.
24.B.推理判斷題.由文章內(nèi)容可知,這是一份調(diào)查報告,是針對美國老年人的健康習(xí)慣所做的調(diào)查.這樣的文章理應(yīng)不會出現(xiàn)在"旅游指南""書評""官方文件"里,故排除 A、C、D.流行雜志做這樣的調(diào)查報告很常見,故選 B.
點評 考察學(xué)生的細(xì)節(jié)理解和推理判斷能力,做細(xì)節(jié)理解題時一定要找到文章中的原句,和題干進(jìn)行比較,再做出正確的選擇.在做推理判斷題不要以個人的主觀想象代替文章的事實,要根據(jù)文章事實進(jìn)行合乎邏輯的推理判斷.
