不是选C吗?
as——先行词用such修饰,则规定用关系代词as作从句引导词,as在从句中做宾语.再说了,即便没有such,而先行词在主句中做表语,仍不能使用which引导定语从句.比如,It is quite a useful dictionary__everyone wants to buy.只能用that,不可用which.
wants——一般情况下,and连接两个单数可数名词做主语时,谓语动词要用复数.
如：The boy and the girl
decide to face the problem together.
男孩和女孩决定一起面对问题.
但若者两个可数名词前加了every或each时,按照英语的习惯,位于动词要用单数形式.
即：each/every+单数名词+and(each/every)+单数名词时,谓语动词用单数.
如：Every boy and every girl has the right to receive
education.
每个男孩和女孩都有接受教育的权利.
