[文法] might be or might have been

[graphic (Sonia)]

   It is believed that your last name gives a hint about your ancestors' job.

   For example, if your last name is "cook", then your great grandfather

   ____  a cook.


   (A) might be   (B) shall be  (C)might have been  (D) should have been

  Ans: (C)

  是否請各位高手幫我看一下這一題該如何解釋呢?

  為什麼要用"might have been" 而不是 "might be"

  Thanks !!!

推 Newface:因為have been 應該帶有"曾經是"的意思吧?
→ Newface:而might be 給我的感覺像是"即將會當"的意思!
