14、谓语动词include，且spend和谓语动词之间没有连接词，所以spend使用非谓语形式，spend和time之间构成被动关系，且表示已花在工作和娱乐上的时间，所以用过去分词作定语，故填spent。【2题详解】考查冠词。句意：锻炼是缓解压力的最有效的方法之一。形容词最高级前，用定冠词，故填the。【3题详解】考查定语从句。句意：跑步、散步或做运动会带来让你感觉更好的身体变化。causes和make都是谓语动词，所以空格处用连接词，“_ make you feel better.”修饰physical changes，是定语从句，定语从句中缺少主语，先行词为物，故填that/which。【4题
