36．句意：孩子们在后院玩耍时，一只小猫试图穿过他们的院子。
此处作谓语，根据后文是when引导的过去时的时间状语从句，可知此处用过去进行时was/were doing；根据地点状语in their backyard，可知此处选play玩耍，是动词，根据主语kids为复数，可知用were，故答案为were playing。
37．句意：这只猫看起来如此可爱以至于孩子们都求着要养它。
此处缺谓语，根据其后是形容词，可知此处可填系动词，故选look看起来，是系动词，根据后文begged用过去时，可知此处也用过去时，故答案为looked。
38．句意：你认为爸爸会允许我们养它吗？
此处缺谓语，根据固定搭配allow sb. to do意为“允许某人做某事”，可知选allow允许；根据语境，可知要用一般将来时will do，故答案为will allow。
39．句意：去吧，问问你爸爸。
根据语境，可知此处用祈使句表建议或命令，应该填动词原形；根据句意，可知选ask问，是动词，故答案为Ask。
40．句意：我们到目前为止已经喂养五只猫了。
根据时间状语so far，可知要用现在完成时have/has done；根据前文说要养猫，可知此处选feed喂养，是动词，其过去分词为fed，故答案为have fed。
41．句意：你妈妈和我没有时间去照顾更多了。
此处作后置定语修饰其前名词time，可知用动词不定式to do；此处构成动词短语take care of，意为“照顾”，所以选take，故答案为to take。
42．句意：看着孩子们脸上伤心的表情，这个父亲改变了主意。
此处缺谓语，根据后文said用过去时，可知此处也用过去时；根据后文父亲又答应了可以养这只猫，可知此处选change改变，是动词，故答案为changed。
43．句意：既然你们如此喜爱它，你们可以养它。

44．句意：但是，这个父亲补充说，他们必须承诺自己照顾小猫。
此处作宾语从句的谓语，此处构成promise to do承诺做某事，可知此处选promise承诺，是动词；根据语境，此处要加情态动词must表“必须”，情态动词后用动词原形，故答案为must promise。
45．句意：然后，这只猫就被孩子们取名为“Lucky”了。
