40、主语为an ambulance，所以谓语动词用单数的was, was之前不是主语，根据among判断应填复数形式，故用vehicles。2to get考查非谓语动词。try to do sth. “努力做某事”， 所以应填不定式形式作宾语，故填to get。3which考查定语从句的引导词。根据句子结构判断，此处应填which引导非限制性定语从句，并在从句中作主语，which指代的是前面句子的内容。故填which。4selfish考查词性转换。此处需要形容词作定语修饰people，结合句意判断应填selfish，表示“自私的”。5losing考查非谓语动词。risk doing sth. “冒
41、做某事的风险”，所以应填动名词形式作宾语。6more考查比较级。根据后面的than判断，此处应用比较级形式，表示“多为别人着想”。7be avoided考查动词的语态。avoid “避免”，与主语mistakes为动宾关系，所以应填被动语态形式。8it考查代词。work wonders “创造奇迹；取得惊人成就”。根据上下文判断，此处指的是“学会表现出善良” 会创造奇迹，所以应填it，代替learn to show our kindness作主语。9but考查固定句型。此处为“not . but .”句型，表示“不是而是”。10strengthen考查词性转换。此处需要动词作谓语，所以应变为strengthen表示“加强；强化”。
