B 题目应该是这样的吧:
This is one of the books which are sold in that bookstore.
d答案选择B
which引导定语从句,修饰前面的books,这里book是复数名词,因此be动词用are。be+过去分词,表示被动。
A
one of 后接可数名词复数, 表示什么中的一个,动词用单数第三人称。
One of the apples has gone bad.
但是要注意下面的定语从句:
He is one of the boys who enjoy playing basketball.定语从句修饰the boys。
He is the only one of the boys who enjoys playing basketball.one前面有定冠词the的时候,定语从句是修饰one的,所以动词要用单三形式
