A．capabilities
B．responsibilities
C．proficiencies
D．efficiencies
参考答案：A
解析： 空格所在句子是help students acquire a sense of commitment by planning for roles that are within their (110) and their attention ps，其中that引导的定语从句修饰先行词roles，表示通过涉及一些在学生……范围之内和其注意力持续时间之内的角色，帮助学生获得一种责任感。因此考生需要判断这些角色在青少年的什么范围之内。四个选项中首先排除proficiency和efficiency，它们不能和within搭配，且句意不符。选项responsibilities有很大干扰性，因为它是commitment的近义词，但考生需仔细考虑一下，此处responsibilities修饰的是roles，“在责任范围内的角色”不合句意。只有capabilities符合句意的要求，填入空格后意为一些学生能力范围和在其注意力持续时间之内的角色，既表示学生有能力完成，也承接上文，说明学生的注意力还可以集中。
