John's mother left him when he was a baby. His was brought up by his aunt.
His aunt took care of him as if she _____ his own mother.
(A) Is (B) was (C) were (D) had been
可以解釋一下所該答案的原因嗎?

C 假設語氣

as if(宛如、好像)子句為假設法，與現在事實相反，be動詞一律用were

D吧 這是與“過去”事實相反的假設欸

正確答案是d嗎? 我覺得是d

是不是兒子，真相只有 true or false 哪有過去式。Were 就對了。

were

認為是與過去事實相反的可能是覺得當年抱錯小孩之類的（誤）

were。與事實相反地假設。血緣關係沒有「過於」或「現在」口語上was也是可接受的答案。written English就不行
