what 的意思是 the animal which,在E里面 which are from the animal which appear to be,啰嗦,而且动词不对。
appear应该是appears
what 指代what = the thing that, what沒有一定要往前找指代對象, 如果有be動詞, the thing往後面找應該是the second most massive dinosaur,在E里面 which are from the animal which appear to be,啰嗦 因为appear to be 后面跟的是dinosaur,appear 的形态与后面的名词有关;这情况类似于there be 句型,因此应该是appears to be
what +單數動詞
what 指代后面的dinosaur,用单数appears,appear不符合单复数.
which are可以省略,且appear不符合单复数
非限定關代使其變成介紹用具,huge fossil bones變成專有名詞,而不需要再詳加限定是什麼bones了。
A、B、C与前面从句的逻辑主语不一致,且C中it指代不清 D is the best , what 指代后面的dinosaur,用单数appears E,which are可以省略,且appear不符合单复数 what 的意思是 the animal which
主谓一致 which are 可省
特指一个dinosaur,应用单数,which are可以省略;两个选项选最优
