Answer 1

分析 本文是關(guān)于健康習(xí)慣的調(diào)查．從一天刷幾次牙，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(guó)老年人的習(xí)慣并給出了專家建議．

解答 25---27 CCB
25．答案C．細(xì)節(jié)理解題．根據(jù)"A full 33% of seniors brush their teeth only once a day．"可知大約三分之一的美國(guó)老年人一天只刷一次牙，故選C．
26．答案C．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C．
27．答案B．細(xì)節(jié)理解題．根據(jù)"Do you know it is not your toilet but your kitchen sponge（海綿）that can carry 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B是正確的．

點(diǎn)評(píng) 閱讀理解解題方法：
1．直接法和排除法．所謂的直接法即為在文章中很容易找到的答案，類似這樣的題目大多設(shè)計(jì)在開頭的小題目中，較為容易；排除法是根據(jù)你所閱讀的印象，可以發(fā)現(xiàn)這是虛假信息，在干擾你的思維，有的干擾項(xiàng)在文章中隱藏得很深，需要你加倍留意．
2．相似法和跳讀法．考生可以根據(jù)題干中所出現(xiàn)的相關(guān)的重要的某幾個(gè)信息詞或句式，在文章的某一處找到其相同或相似的詞及句式，然后根據(jù)此處所提供的信息進(jìn)行加工整合，最終提煉出精華，實(shí)際上這一處理過程就包含了跳讀法，考生不需要逐字逐行地去查找，根據(jù)題干的提示跳讀找到相關(guān)的句子，加以分析推敲，從而找到正確的答案．
3．猜測(cè)法和推敲法．在高考的試題當(dāng)中經(jīng)常會(huì)出現(xiàn)這樣的題目，即讓考生根據(jù)某一段話來猜測(cè)某一生詞或句子的意思，對(duì)此考生只能在某一出處細(xì)細(xì)品味推敲上下文所包含的意思，從而找到答案．
4．概括法和推理法．此種方法主要用來解決一組題目中的最后一二道綜合題目，這類題目難度相對(duì)較大，需要考生具有一定的解題能力，運(yùn)用概括推理法的前提條件是認(rèn)真閱讀文章開頭一段和最后的結(jié)尾，同時(shí)文章中每一段的第一句話．
