Past GMAT questions have required that any new copy that or those agree in number with the previous version. If you must change number, repeat the noun:
Right:Her COMPANY is outperforming that of her competitor.
Wrong: Her COMPANY is outperforming those of her competitors.
Right: Her COMPANY is outperforming the companies of her competitors.
我主要是不太清楚the meaning of "number in previous version".求解答！谢谢 作者: Juno_Dai 时间: 2020-7-3 13:52
代词有两类绝对错误，一个是无指代，一个是和指代对象的单复数不一致。
that 和 those 本质上还是一个代词。所以在比较当中把它们用来指代的时候它们也必须要优先遵从这两个规则：
Her COMPANY is outperforming that of her competitor. that指代的是前面的COMPANY，有指代且单复数一致，正确。
Her COMPANY is outperforming those of her competitors. Those指代的是前面的COMPANY，有指代但是单复数不一致（COMPANY是单数，those是复数），错误。 作者: 尚舟明 时间: 2020-7-3 14:53
