[Jessy]

A challenging new area in inorganic chemistry is ___ the role of transistion metals in the biochemical catalysts called enzymes.
(a) that of understanding
(b) to have understanding understanding錯
(c) the understanding 名詞型態,造成與後面the role形成 beV+N+N
(d) understanding that that後面應接子句,後面缺動詞

[jcgygy]

能請問一下(A)是為什麼對呢?

[apoptosis]

A答案在這裡的that應該是一般代名詞而非關係代名詞所以在文法上並沒有錯吧

[yongzhou]

可以填
a)that of understanding
to understand
the understanding of

[ustoday]

(B) 選項改成to have understand 對嗎?
另
(A) 中的that 試代名詞的話 是指代誰勒

[nexxt0722]

A--->that代替an area
B--->就文法上,應該改成to have understood, 但就語意上,用完成式並不太適當,所以即使改成to have understood也不正確
