Question

17．Swimming is one of those activities that can be learned early in life．Little children can learn to swim as soon as they walk．In fact，you need the same skills in walking as in swimming．However，I believe that five is the best age to learn．By five or six，a child knows fear of water，a very important thing to know．It's wise to be afraid，to recognize true danger．Young ones understand that the water can sometimes be very dangerous．
To really benefit from swimming，every swimmer should learn，as soon as possible，these four basic strokes（游泳姿勢(shì)）； butterfly，backstroke，Breaststroke，and crawl．I feel that one of these-the breaststroke-is different from the others，since some young swimmers use this stroke naturally，without any training．
In swimming there are certain rules every swimmer should follow：
1）．Never swim alone!No matter how good you are in the water，don't risk drowning（溺水，淹死） by swimming alone．If you swim by yourself，with no life guards or friends with you，you may get into trouble．
2）．Don't go beyond your abilities．Most swimmers know enough not to swim too far from the bank or the beach，Showing off by doing dangerous tricks is no good．Swim safely and you will continue to swim and alive．
3）．Don't smoke．Swimming depends on a healthy body； good lungs are part of it．
4）．Work at any activity that builds muscles．

Answer 1

分析 文章主要講述了游泳是在早期能夠?qū)W習(xí)的運(yùn)動(dòng)之一，并簡(jiǎn)單介紹了游泳的類(lèi)型，及其在游泳過(guò)程中必須注意的幾點(diǎn)規(guī)則．

解答 21．C細(xì)節(jié)理解題．根據(jù)第一段第二句Little children can learn to swim as soon as they walk．可知小孩子在開(kāi)始走路后，就可以學(xué)習(xí)游泳，說(shuō)明C正確．
22．D．細(xì)節(jié)理解題．根據(jù)第一段后半部分By five or six，a child knows fear of water，a very important thing to know．It's wise to be afraid，to recognize true danger．可知，懼怕水能夠意識(shí)到危險(xiǎn)的存在，從而去尋找解決辦法，這是一種好的現(xiàn)象；故選D．
23．A 細(xì)節(jié)理解題．根據(jù)第二段最后一句I feel that one of these---the breaststroke is different from the others，since some young swimmers use this stroke naturally，without any training．可知，年輕的游泳者最初就是采用的蛙泳的方式，故選A．
24．C 推理判斷題．根據(jù)If you swim by yourself，with no life guards or friends with you，you may get into trouble．這里的get into trouble指淹死．故C正確．
25．A 細(xì)節(jié)理解題．Don't smoke．Swimming depends on a healthy body； good lungs are part of it．由此可知，吸煙對(duì)肺不好，而游泳需要一個(gè)健康的肺．故答案為A

點(diǎn)評(píng) 本文是科教類(lèi)閱讀理解．做這類(lèi)題材閱讀理解時(shí)要求考生對(duì)文章通讀一遍，做題時(shí)結(jié)合原文和題目有針對(duì)性的找出相關(guān)語(yǔ)句進(jìn)行仔細(xì)分析，結(jié)合選項(xiàng)選出正確答案．推理判斷題也是要在抓住關(guān)鍵句子的基礎(chǔ)上合理的分析才能得出正確答案，切忌胡亂猜測(cè)，一定要做到有理有據(jù)．
