问题 According to Darwin, random changes that enhance (a species’) ability (for surviving) (are) naturally selected and passed on (to succeeding) generations.
选项 A、a species’
B、for surviving
C、are
D、to succeeding
答案B
解析 改for surviving为to survive。本题考查非谓语动词的用法。由于ability一词要求不定式做后置定语来修饰，故只有将for surviving改为to survive。
