(Para.3)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.
26. In Paragraphs 1 and 2, the text shows PTK's ______.
27. PTK is used to ______.
[A] locate one's birth place
[B] promote genetic research
[C] identify parent-child kinship
[D] choose children for adoption
这道题当中26题题目中说是根据第一和第二自然段，我们可以知道PTK怎么样，根据题文同序原则那么27题应该是从第三段找答案。那我们来观察一下27题，当中说PTK is used to，这里面提到了两个信息PTK 和一个动词短语 is used to。先根据PTK去找的话，不容易在第三自然段中找到这个缩略词，但是除此之外，我们会发现根据动词词组却很容易找到相关的定位句：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.这句话中出现了Use，除此之外paternity and kinship testing就是PTK的全称，而且我们通过大量的历年试题发现，在一些特殊的标点符号处常常是一个命题点，那么在这个句子当中，我们会发现有一个冒号，那就更加肯定此句就是我们需要定位的句子。这句话的理解为“其中最受欢迎的是亲子关系和亲属关系测试，被收养的孩子可以用它来找到自己的亲属，而家庭可以用它来追踪被收养的孩子。”有此不难得出正确选项为C。
