故事文本分析》1.故事大意:在主人公 Jenny小时候,爸爸死于率祸,妈妈一人无法抚养她和她的妹妹,所以把比她小两岁的妹妹送给他人抚养。几年后,妈妈与收养家庭失去了联系。因病即将离世的妈妈告知Jenny此事,让她找到失散的妹妹,并向她表达妈妈的愧疚之情。妈妈的离世使Jeny十分悲伤,但是想着世上还有一位妹妹,心中有些许安慰。然而Jeny不知如何寻找,朋友向她推荐了一个寻亲网站。2.主题词:亲情。续写悲念:寻亲网站— Google Earth能否找到主人公 Jenny的妹妹呢?写作思路点拨》思路:第一段首句句意为“听到这些话(即有一个寻亲网站),我感到十分高兴。”接下来,主人公则会从网站入手,开始自己的寻亲之路。寻妹妹的信息如同大海捞针,其中必定经历曲折、失落与沮丧。第二段首句句意为“(我)激动地读着(网上的)那条信息。”由此可知,接下来必定会得知有希望的消息,姐妹俩最终得以团聚。点拨:续写时,考生可以借助已知线索,如妈妈的姓名( Maryann)、妹妹的年龄( two years younger)以及收养家庭的信息等作为写作线索。首段可描写Jeny搜寻信息的不易和内心感受。第二段故事出现反转,有关妹妹的信息浮出水面,接下来就是姐妹团聚的情节,考生可以围绕人物的对话或者主人公的内心情感进行描写。【参考范文】After hearing the words, I felt very happy.

17.【解】本题考查正弦定理、余弦定理在解三角形中的应用,三角形面积公式(1)因为(c-b)sin(A+B)= asin a- bsin B所以(c-b)sinC= asin a- bsin b,由正弦定理得(c-b)c=a2-b2,即c2+b2-a2=bc由余弦定理得cosA=c2+b2-a212b0又A∈(0,π),所以A=由正弦定理得mAB36sin60°sinB则sinB=26m60°=2又b
