過去完成進行時
What's on your mind today, Dr. Jill
吉爾博士，你今天想講什么？
Hi John, I was looking back through my diaries again.
嗨，約翰，我又在翻我的日記回顧過去了。
You have some crazy stories in them!
你在日記里記錄了一些瘋狂的故事！
I know! I was just noticing how often I wrote about the duration of past activities.
我知道！我只是注意到我經(jīng)常寫過去活動的持續(xù)時間。
Can you give an example?
你能舉個例子嗎？
Listen to this sentence: I had been dancing for four hours straight before the police arrived.
聽這句話：在警察來之前，我已經(jīng)連續(xù)跳了四個小時的舞了。
Oh wow! Was this one of the crazy rock concerts you used to go to?
哦，哇哦！這是你過去常去的瘋狂搖滾音樂會之一嗎？
I still go to them!
我現(xiàn)在還是會去！
But the one I wrote about in my journal was a long time ago.
但我在日記中寫到的那個是很久以前的事了。
I noticed you used the past perfect continuous--I had been dancing for four hours...
我注意到你用了過去完成進行時——我已經(jīng)跳了四個小時的舞了……
Right! The basic form is "had + been + verb + -ing (present participle)".
沒錯！它的基本形式是“had+been+v.-ing（即現(xiàn)在分詞）”。
The past perfect continuous suggests an action went on for a certain amount of time in the past before another action or event took place.
過去完成進行時表示在另一個動作或事件發(fā)生之前，過去發(fā)生的一個動作持續(xù)進行了一段時間。
Do you have more examples from the diary?
你的日記中還有例子嗎？
Yes, here's another one: I had been sitting in jail for eight hours before my husband came to pay the fine.
是的，還有一個：在我丈夫來交罰款之前，我已經(jīng)坐牢八個小時了。
Wow! So the action in progress was "sitting in jail", and the action ended when your husband arrived to get you out of jail.
哇！因此，正在進行的動作是“坐牢”，當你的丈夫來把你從監(jiān)獄里救出來時，這個動作就結束了。
Yes, and it was the last time!
是的，這是最后一次！
And that's Everyday Grammar.
以上就是今天的《每日語法》。
