分析 一些学生是如此的年幼以至于不能分清好坏.
一些学生不够年长去分清好坏.
解答 答案:old enough.上文是so…that表示如此…以至于做某事,表示一些学生是如此的年幼以至于不能分清好坏,也就是还不能年长去分清好坏,表示不够怎样去做某事用adj/adv+enough+to do sth,这里是年长的用形容词old.故答案是old enough.
点评 too…to(太.而不能)
so…that(如此.以至于)
adj enough to…( 足够…去做某事)三者之间可以互换she is too young to go to school=she is not old enough to go to school=she is so young young that she can not go to school
