2017考研英语长难句分析每日一句（101）
Among the most popular: paternity and kinship testing, which adopted children can use to find their biological relatives and families can use to track down kids put up for adoption. DNA testing is also the latest rage among passionate genealogists-and supports businesses that offer to search for a family's geographic roots.
译文：其中最受欢迎的是父子和血缘关系检测，被收养的孩子可以利用它找到自己的血亲，家庭成员可以用它来追踪到被收养的孩子。DNA检测最近也大受热心的族谱学家的追捧，并且给那些寻找家族地理根源的商业活动提供了支持。
点睛：第一句结构较为复杂，主干部分Among the most popular: paternity and kinship testing省略了谓语动词，该部分在语句功能上相当于Among the most popular is paternity and kinship testing.which引导的两个并列的定语从句adopted children can…和families can…修饰paternity and kinship testing。第二句的主干为：DNA testing is the latest rage…and supports businesses。
rage在句中意为“狂热，风行”，如：
