were going to 過(guò)去將要干什么...

　　因為 WERE 表明 過(guò)去了.而 BE GOING 又是進(jìn)行或將來(lái)的意思

　　所以是過(guò)去將來(lái)時(shí)

　　比如:they were going to pick apples yesterday

　　他們昨天正準備摘蘋(píng)果的

　　過(guò)去將來(lái)時(shí)

　　過(guò)去將來(lái)時(shí)：聽(tīng)起來(lái)很矛盾，但認真想時(shí)，因為對過(guò)去來(lái)說(shuō)也有將來(lái)。例如：She called me when I was going to do some cleaning after dinner yesterday.

　　昨天晚飯后我要去洗衣服時(shí)她給我打電話(huà)。
