The book store sells books that --- children.A.is suitable for B.are suitable for

问题描述:

The book store sells books that --- children.A.is suitable for B.are suitable for
be suitable for 的适当形式填空.本人认为此句型是that引导的定语从句,应该与that 前面的名词复数保持一致,选择B;但that引导(而不是those)是否应该与其保持一致,be 动词也保持单数形式,选择A?如何选择答案A 或B?并说明理由根据,

选择B,保持一致是基本.在这里用that,which都可以,但显然不能用those,这点从根本上考虑错误.
