分析 研究人員發(fā)現(xiàn),灰海豹可以利用一些安裝在魚身上的跟蹤器來捕獲獵物.
解答 28.D 詞義指代題.根據(jù)第一段的Tiny monitoring devices have become an increasingly common way for scientists to study elusive animals可知,the trick指代的是在海洋動物身上安置跟蹤器一事.故選D.
29.C 推理判斷題.根據(jù)第三段的However,after they had been in the pool a few times,they started locating the tagged fish much faster.以及第四段的Sure enough,the seals were all attracted to the one that was sending out signals.可推斷,他們得出的結(jié)論是海豹確實可以通過跟蹤這些跟蹤器來捕獲獵物.故選C.
30.B 推理判斷題.根據(jù)第五段的Sadly,predators like sharks that have been tagged by scientists may be negatively affected,as pings they emit could warn their prey of their presence.可推斷,這些研究人員似乎相信安裝有這種跟蹤器的鯊魚不好捕食.故選B.
31.A.結(jié)構(gòu)題.有全文可知,第一段講述了科學(xué)家們發(fā)現(xiàn)灰海豹可以利用一些安裝在魚身上的跟蹤器來捕獲獵物.二三四段講了實驗過程,最后一段綜述這一發(fā)現(xiàn)的影響,故選A.
