分析一下这句话的句子结构 主句的谓语是什么？为什么question用ing不用to do？谢谢大家A few posts are published questioning the rational of groups,which argued that only by obtaining data from annual standardized test can futher the goal of achieving educational equity.为什么question用ing,不是to do？还有分析翻译一下句子，谢谢大家了

Answer 1

A few posts are published questioning the rational of groups,which argued that only by obtaining data from annual standardized tes是主语。 the goal of ach...是谓语。questioning是动名词 是修饰前一词的，又被后面修饰。to do只能接动词。

Answer 2

be动词（are）后，动词要转成非谓语结构，后加ing

追问

published呢？这句话谓语是啥

追答

are，就是这句话的be动词作谓语，在其后的动词也可以做谓语，一句话有两个谓语就重复了，所以要转成非谓语＋动词ing。而publishrd是adv.（副词，不是动词）修饰动词question的，所以不影响question＋ing。
