18．In Asia，there are special competitions where kites have complex designs and are fitted with instruments that make musical sounds as the wind blows through them．Although all kites have a similar structure （结构），they are widely different in size and shape．Kite-fighting competitions are also held，in which competitions us their kites to attack and bring down their opponents'（对手）kites or cut their strings（线）．
For more than 15years，the Big Wind Kite Factory has been giving kite-making and kite flying classes for the children on an island in Hawaii．In its kite-making lessons，students can make kites in as little as 20minutes!Children as young as four years old can learn how to fly a kite．Jonathan Socher and his wife Daphne started the kite factory in 1980．Their kites are made of nylon（尼龙）．Their designs are Hawaiian themes created by Daphne．The designs are cut out of the nylon with a hot knife that seals the edges and then fastened directly onto the kite．
The kite that is used to give lessons is regular diamond kite with a rainbow pattern．The difference between this kite and the ones they make during the lessons is that it is a two-string controllable kite．Big Wind employees fly the kite and for a few minutes show students how pulling on one line and then on the other controls the direction the kite goes in．Then the controls are given to the students．
Jonathan insists that it is not necessary to make a huge impressive kite to have fun making and flying kites．Even the simplest structure can work，and can give hours of fun．Go on，give it a try!

分析 本文属于记叙文阅读，作者通过这篇文章主要向我们介绍了The Big Wind Kite Factory的相关事情，主要介绍了它的创始人，创办的目的，员工及学生可以做的事情．
解答 4．D，细节理解题．根据第二段最后一句可知，使用加热的刀是切割（cut）尼龙，而不是iron the nylon（熨烫尼龙），故A项错；B项与第三段最后一句"Then the controls are given to the students．"相悖；根据第一段最后一句可知C项错．由第二段倒数第二句"Their designs are Hawaiian themes created by Daphne．"可知D项正确．
5．A，细节理解题．根据第三段第二句"The difference between this kite and the ones they make during the lessons is that it is a twostring controllable kite．"可知，与孩子们在制作课上制作的风筝不同的是飞行课上使用的风筝是双线控制的，故选A项．
6．B，观点判断题．最后一段介绍的是Jonathan的观点．根据"…it is not necessary to make a huge impressive kite…"可知A、D两项不正确；C项与最后一段第二句"Even the simplest structure can work，and can give hours of fun．"相悖．结合最后一段可推知，Jonathan认为任何类型的风筝都可以给你带来快乐，故选B项．
7．A，主旨大意题．本文主要是介绍一家风筝厂15年来一直为夏威夷一座岛屿上的孩子们开设风筝制作和风筝飞行的课程．文章主要聚集于这家工厂，讲述kitemaking and kiteflying lessons是为介绍这家工厂服务的，另外文中涉及两类课程，B项只是"风筝飞行课程"，显然不全面．文章首段提到特殊的比赛，是为了引出风筝比赛，进而引出本文的中心话题，选C项就会本末倒置．D项"风筝制作过程"在文中并未涉及．
点评 考查学生的细节理解和推理判断能力．做细节理解题时一定要找到文章中的原句，和题干进行比较，再做出正确选择．在做推理判断题时不要以个人的主观想象代替文章的事实，要根据文章事实进行合乎逻辑的推理判断．
