学生写了一个语法错误的句子,我想请教一下各位老师,关于这题的错误我是否解释正确:
学生给的句子是:it is still cannot be ascertained that...
我对学生说的是:it 作形式主语,你把that后面的真主语放到谓语动词前面就是原本的句子,但现在你告诉我哪一个才是谓语?是 is 还是 cannot be asertained?要么改成 it is still not ascertained,或者 it still cannot be ascertained.
但其实我自己都不明确这属于什么错误,是谓语重叠吗?
it is still cannot be ascertained that...
解答:网友自己造的这个句子,在“主句里”有2个谓语动词,属于严重违背或者违反“英语语法原则”,网友必须要知道,不管是主句还是从句里,都必须只能出现 1套“主语+谓语动词”结构。
(1)It is still can not be ascertained that(主语从句)....(出现了 is , can't be ascertained 2个谓语动词,属于严重语法错误。必须去掉一个谓语动词)
(2)It can not be ascertained if/whether(主语从句) (正确)
It can't be ascertained if the land is still owned by the government. 不能确定这块土地是否仍属于政府所有。
(3)It is ascertained that(主语从句) (正确)
It is ascertained that the land is still owned by the government. 现在确定这块土地是属于政府所有。
