70.the→a　这里第一次提到balloon,不特指,因此应该用a。

71.discover→discovered　本文讲的是过去发生的事情,应该用过去式discovered。

72.keep→keeping　keeping the balloon up,现在分词作定语修饰The air,was escaping是谓语。

73.√

74.up→down　从句意来看,“维持气球上升的气体释放得很快,气球正在下降”。因此应将up改成down。

75.light→lighter　从句意来看,“两个人把他们所有的装备扔进水里,使气球更轻”,因此应改成lighter。

76.So→But　前一句话讲了“气球又开始升高了一些”,

后面说“气球仍然离水太近”,因此两句话是转折关系,应该将So改成But。

77.his→their　主语the men是复数,因此后面也应该相应地用复数their。

78.去掉waiting后的for　wait for应该接宾语,wait后面加to接动词原形,因此for不需要。

79.在see前加to　be surprised to do sth.,意思是“很惊奇地做某事”,因此应在see前加to。
