I'll show you a store [in which] you may buy all [that ]you needA where ;which B in which ;that C which ;that D that ;that主句跟从句是什么关系,为什么选B
选B.我是高中英语老师,这个题主要就是考察定语从句.第一空可填in which 或者where,它们都引导一个定语从句,in which 或者where在从句中做地点状语,指代in the store.第二空只能填that,因为先行词是all,that也是引导定语从句,指代all(the things),在从句中做宾语.
主句是 I'll show you a store 第一个从句整个是[in which] you may buy all [that ]you need,修饰store
而其中[that ]you need又是第一个从句中的一个小从句,修饰all.
