  Question 16

  答案：baleen whales

  關鍵詞：stereoscopic vision

  解題思路：根據定位句信息，可知答案是baleen whales。

  Question 17

  答案：forward downward (IN EITHER ORDER)

  關鍵詞：Dolphins, porpoises

  定位原文：第4段第1句“On the other hand, the position of the eyes in most dolphins and porpoises suggests that they have stereoscopic vision forward and downward.”

  Question 18

  答案：(the) freshwater dolphin(s)

  關鍵詞：forward and upward

  定位原文：第4段第2句“Eye position in freshwater dolphins, which often swim on their side or upside down while feeding, suggests that what vision they have is stereoscopic forward and upward.”

  劍橋雅思4Text1閱讀答案解析Question 19

  答案：(the) water

  關鍵詞：bottlenose dolphin

  定位原文：第4段第3句“By comparison, the bottlenose dolphin has extremely keen vision in water. Judging from the way it watches and tracks airborne flying fish, it can apparently see fairly well through the air-water interface as well.”

  關鍵詞：best/cetaceans

  定位原文：第6段第1句“Although the senses of taste and smell appear to have deteriorated, and vision in water appears to be uncertain, such weaknesses are more than compensated for by cetaceans’ well-developed acoustic sense.”
