a cat's ability to survive falls is based on fact 请问to survive falls是一个词组还是什么,
怎么去科学理解,或这是什么语法现象

这句话的主语部分是"A cat's ability to survive falls",其中 ability是主语中心语,所以谓语动词用单数形式(is).
谓语是"be based on “ 以…为基础；建立在…基础上
宾语是"fact"--事实
难点在于对"survive"这个单词的使用和理解上
Survive 既是及物动词又是不及物动词
作及物动词讲时,译为：幸免于,从…逃生；经历…后继续存在；从...坚持过来
例：
(1)to survive the fire
从大火中逃生
(2)to survive the difficulties
渡过艰苦时期
故由此可知 to survive falls 可译为：从跌落中生还.
【fall】在这里的意思是“掉落的动作”,因此,该词要用复数表示“很多次”
整句的意思为：猫从跌落中生还的能力是建立在事实的基础上的.
