1. 「I have a friend whose father is a teacher」這句相信沒大問題,在形容人的時候以以他有關係的事、物或人解釋可以用whose;但如果形容物件可以如何形容,以下句子是否正確(我知道這個句子不太完美,只是想說出我想問的內容):
This PC which its price is $1000 is powerful.
2. 正確的句子是what product(s)/service will you concern 還是 which product/service(s) will you concern?為什麼?我覺得是後者較正確。有時候覺得在某些句子相當難分別。
3. This file is covering forecast of this current year for your reference還是This file is about AOP of this current year for your reference哪個正確?covering、about在此句型有何分別、如何判斷可怎樣用?
