推理判断题。从文章第一段中的“shewasunemployed,hadneverbeenmarriedand‘neverbeenkissed，actually’”和“fromavillageinScotland”这些信息可推知，SusanBoyle来自社会的底层，所以选A项。17．C 细节理解题。从文章第二段中的“everyone—includingthejudges—seemedlaughingather”可知，人们最初都嘲笑她，看不起她。答案选C项。18．B-14-\n 推理判断题。从文章最后一段的内容可推知，她红遍全球要归功于互联网的传播，答案选B项。19．C 推理判断题。通读文章第四段的内容可推知，该段主要讲述SusanBoyle在美国的影响，据此选C项。B美国洛杉矶的一位数学老师把复杂难懂的数学概念变成了说唱乐，从而让学生们如痴如醉地在数学公式里遨游。20．C 细节理解题。根据文章第二、三段可知LaMarQueen在从教之初并不受学生欢迎，他用说唱的方式授课后才出名的，可排除A项。根据文章第一段Theiralgebrateacher(他们的代数老师)以及后文多次提到的“math”可知答案为C项。21．C 推理判断题。根据全文尤其是第一、二段内容可知LaMarQueen教数学的方式与众不同，正因为他独特的教学方法使他获奖，故选C项。22．A 推理判断题。题干中thelastparagraphbutone是“倒数第二段”的意思，注意审题。从校长调查到学生说的话可知LaMarQueen的教学被校长和学生认可。故选A项。23．B 推理判断题。全文介绍LaMarQueen用说唱的方法教授数学，属于教育类文章。故选B项。Ⅲ.24.on 25.filled 26.bridges 27.convenient 28.furniture29．that
