[听力原文]26-28 Good morning students. This class I brought two books that I had been reading. I want to introduce them to you because I hope you have been able m read the two hooks. They are about speech and hearing problems that I put in the library. (26) Today’s lecture deals with the presence of the unusually large deaf population that had existed on the Massachusetts island of Martha’s Vineyard for about three centuries. From the settlement of the island in the 1640s to the 20th century, the people there, who were descended from only twenty-five or thirty original families, married mainly other residents of the island. They formed a highly inbred group, producing an excellent example of the genetic patterns for the inheritance of deafness. Indeed in the lair: 1800s, one out of every twenty-five people in one village on the island was born deaf and the island as a whole had a deafness rate at least seventeen times greater than that of the rest of the United Status. (27) Even Alexander Graham Bell, the inventor of the telephone and a prominent researcher into hearing loss, visited Martha’s Vineyard to study the population. But because the principles of genetics and inheritance were still unknown, he was not able to explain the patterns of deafness and why a deaf parent did not always have deaf children. (28) In the 20th century, the local population has mixed with people off the island and the rate of deafness has fallen. 26．What is unusual about the island of Martha’s Vineyard [听前猜测] 四个选项都是陈述句，而且都是关于不同的方面，settled，Alexander Graham Bell，its residents，family，各个的侧重点各不相同。 [答案详解] 综合理解题[考频：14]。文章一开始就提出了鲜明的观点，the presence of the unusually large deaf population。问题是关于这个地区人们的特殊之处体现在哪里，故答案为C)。 document.getElementById("warp").style.display="none"; document.getElementById("content").style.display="block"; 查看试题解析出处>>
