动作。这一特定的过去时间除有上下文暗示以外, 一般用时间状语来表示。
2. 结构 was / were ( not ) + 动词-ing 3. 句式 肯定式：
I/He/She/It was working. We/You/They/ were working. 否定式:
I/He/She/It was not working.
We/You/They/ were not working.
疑问式和简略回答:
Was I working? Yes, you were. No, you were not. Were you working? Yes, I was. No, I was not. Was he/she/it working? Yes, he/she/it was. No, he/she/it was not. Were we/you/they working? Yes, you/we/they were. No, you/we/they were not. 注：
