1. lives; friendly
2. playful; swimmers
3. hearing; helps
4. danger; cut
5. save; buy; made

1. 第一空：形容词性物主代词our后接名词，此处指代多人的生活，life表示“生活”时的复数形式为lives；第二空考查固定搭配be friendly to sb.，意为“对某人友好”，要将名词friend变为形容词friendly。
2. 第一空：副词so后接形容词作表语，play的形容词形式playful意为“爱玩耍的、活泼的”；第二空：此处表示“它们是很棒的游泳者”，主语they指代复数的大象，要将动词swim变为名词复数swimmers。
3. 第一空：形容词good后接名词，动词hear的名词形式hearing意为“听力”；第二空：由频度副词always可知时态为一般现在时，主语her dog是第三人称单数，谓语动词要变为第三人称单数形式helps。
4. 第一空考查固定搭配in danger，意为“处于危险之中”，要将形容词dangerous变为名词danger；第二空：情态动词shouldn't后接动词原形，所以填cut。
5. 第一空：情态动词can后接动词原形，所以填save；第二空考查固定结构let's do sth.，意为“让我们做某事”，此处填动词原形buy；第三空：things和make是被动关系，用过去分词made作后置定语，构成固定搭配made of，意为“由……制成”。
