答案： 56. animals 考查名词复数。animal是可数名词，根据空前的some可知，应用名词复数。故填animals。
57. to eat 考查非谓语动词。enough to do为固定用法，故空处用动词不定式作定语修饰enough。
58. it 考查代词。it is + adj. + for sb. to do sth. 意为"做某事对某人来说是……的"。it为形式主语，真正的主语为动词不定式。故填it。
59. for 考查介词。wait for sb. to do sth. 意为"等待某人做某事"，为固定搭配。
60. easily 考查副词。空处修饰动词get且意为"轻易地"，故用easily。
61. healthy 考查形容词。系动词stay后应接形容词形式。
62. that/which 考查定语从句。空处引导定语从句，先行词是the body fat，空处在定语从句中作主语，应用which或that。
63. is reported 考查动词的时态和语态。根据空后的now可知，主句应用一般现在时；It与report之间是动宾关系，故用被动语态。
64. predicted 考查动词的时态。根据时间状语"Two years ago"可知，主句应用一般过去时。
65. disappearing 考查非谓语动词。keep doing sth. 意为"继续做某事"，为固定搭配。
