今天小编给大家带来了一些考研长难句的详细讲解，一起来看一下吧。
That concept implies educational opportunity for all children— the right of each child to receive help in learning to the limits of his or her capacity, whether that capacity be small or great.
【画龙点睛】
破折号前的内容是本句的主句，破折号后面的是对educational opportunity for all children的进一步说明，其中包含一个由whether引导的让步状语从句，该状语从句中使用了虚拟语气。to the limits of...意为“达到…的极限”。
【卧虎藏龙】
1、capacity

2、在非常正式的语体中，当条件状语从句或让步状语从句是系表结构时，系动词可以用原形，构成特殊形式的虚拟语气，即be型虚拟语气。be型虚拟语气可用于由if、though、whatever、lest、so long as等引导的分句中，表示推测、让步、防备、忧虑等含义。
