【評論主題】Market growth is the rate ------the overall market is growing.(A)in which(B)for that(C)in whether(D)

【評論內容】

補充一下,這題應該是考 「at the rate 」這個片語+搭配關係代名詞

1.原句拆成兩句:

Market growth is the rate.

the overall market is growing at the rate.

2.「at the rate」-->以什麼樣的比率,介系詞用『at』

3.上兩句拼再一起:Market growth is the rate which the overall market is growing at.

(這裡的which 為受格=that可省略,主是要講市場成長比率這件事)

然後在變化一下,把介系詞「at」提到關代which前面(不可省略),就變成:

Market growth is the rate at which the overall market is growing.

大概是這樣,如有錯誤請再糾...

【評論內容】原因在於短期有固定成本,單純由MC積分算出來只會得到TVC,但不知道TFC,再加上題目也沒有給AC,故無從解。
