Question

 The president of the World Bank says he has a passion for China, ______ he remembers starting as early as his childhood.

A. where                 B. which               C. what                 D. when

Answer 1

 B。本题考查非限制性定语从句的引导词。The president of the World Bank says he has a passion for China为主句，先行词为a passion，通过还原法可知，a passion在从句中作start的宾语。故选B。

【拓展】考生务必牢记：what不可引导定语从句。

【句意】世界银行的主席说，他热爱中国，这种热爱他记得早在童年时就开始了。
