用等巴士做例子︰

present perfect continuous:

i have been waiting for 20 minutes (等到而家仲未有車)

past perfect continuous:

i had been waiting for 20 minutes (等到三點先至有車,而家上咗車)

perfect continuous tense無論present / past 在結尾都需要一個時間副詞/動態來說明當時/某某還在做緊些什麼.


分別1 : present = 說的時候是[ 不超越出 ] 說緊話的期間內.
例 : today , 說的時候今天還未過.


分別2 : past = 說的時候是 [已超越出 ] 說緊話的期間內.
例 : last night , 說的時候是今天.


以說話的時候爲基礎.
