题目内容
7．The only system I know ____ will help you remember what you have heard at a lecture is the system of keeping notes．（ ）| A． | what | B． | that | C． | where | D． | one |
分析 我知道的唯一的能帮助你记住所听报告中内容的体系是记笔记的体系．
解答 答案为B．本题考查定语从句中关系词的选择．题干中空格后面是修饰和限制名词system的定语从句，把先行词system带入到定语从句，完整的定语从句是"the system will help you remember what you have heard at a lecture"；可见the system 在从句中充当主语．
在定语从句中，that可以指代人和物，在从句中往往做主语和宾语．所以答案选择B．A项中what不引导定语从句，所以排除．C项中关系副词where可指代地点在从句中做地点状语，所以排除．D项one不可以引导定语从句．关注：system后的I know也是sysyem的定语从句．
点评 选择定语从句中的关系词，首先要理解各关系词的用法；然后找准先行词，将先行词带入到定语从句；最后根据先行词在定语从句中的作用判断关系词．
