79 ．句意：普雷斯利和黛布是两只雄性海豚，它们待在水族馆里一个有镜子墙的游泳池里。此处是泛指一 个游泳池，pool 以辅音音素开头，应用 a 修饰，故填 a。
80 ．句意：研究人员注意到，当它们在镜子里看到自己时，似乎并不认为自己在看另一只海豚。look“看”， 动词。根据“when they saw themselves in the mirror.”可知，本句是含有 when 的过去进行时态，表示“它们正 在镜子里看自己”，主语是复数，be 动词用 were，故填 were looking。
81 ．句意：也许海豚认出了自己的形象。they 是人称代词主格，空后是名词，所以应用形容词性物主代词 their 修饰名词，故填 their。
82 ．句意：所以他们决定找出原因。decide to do sth“决定做某事”，为固定短语。故填 to find。
83．句意：他们用黑色墨水在海豚身体的不同部位做记号，每周换一个地方。part“部位”，可数名词，different 修饰可数名词复数，故填 parts。
84 ．句意：那个标记是从哪里来的？根据“Where did that mark come...”可知此处是固定短语 come from“来 自”，故填 from。
85 ．句意：但直到现在，只有海豚和类人猿才能认出镜子中的自己，就像你我一样！根据前后句可知，此 处应用 but“但是”表示转折，故填 But。
