At first, it was a shock to my body. I wasn’t feeling great. Let’s read. Look at the sentences. Pay attention to the words in bold. We form the past continuous with was or were + verb-ing. Let's sum up the rules! I/He/She/It was(not) sleeping at eight o’clock last night. You/We/They were(not) Was I/he/she/it sleeping at eight o’clock last night? Were you/we/they No, I/he/she/it was not/wasn’t. you/we/they were not/weren’t. Yes, I/he/she/it was. you/we/they were. Presentation 02 Presentation 02 While we were travelling into space, ground control was following us closely on the screens. We can also use the past continuous with while to talk about two actions happening at the same time in the past. Look! Presentation 02 Presentation 02 Presentation 02 过去进行时 过去进行时主要用于描述过去某个特定时间点货时间段内正在发生的动作,核心是强调动作在过去“进行中”的状态。 过去进行时基本结构和标志词: 基本结构:was/were + V-ing 动词的现在分词 标志词: at that time, at that moment, when, at this time yesterday evening, while Presentation 02 句式 句式 构成 例句 肯定式 主语+was/were+V-ing+其他. He was reading a book at 8 p.m. yesterday. 否定式 主语+was/were not+V-ing+其他. They were not playing football then. 一般疑问句 Was/Were+主语+V-ing+其他? Were you watching TV at that moment? 肯定回答:Yes,主语+was/were. 否定回答:No,主语+was not/were not/wasn’t/weren’t. Yes, I was./we were. No, I wasn’t/was not./we weren’t/were not. 特殊疑问句 (一般情况) 疑问词+was/were+主语+V-ing+其他? What was she doing at that moment? Presentation 02 1、描述过去特定时间点正在进行的动作,常与“at+过去时间点“ ”this time yesterday“等时间状语连用。 At 9 o’clock last Sunday, we were doing experiments in space. She was having breakfast from 7 to 8 yesterday morning. 用法: 2、描述过去某段时间内持续进行的动作,常与“from...to...” “during…”等时间状语搭配。 Presentation 02 用法: when引导的从句常用一般过去时,主句用过去进行时。 3、用于复合句,描述一个动作发生时,另一个动作正在进行,常用when或while引导。 Presentation 02 while引导的从句和主句可都用过去进行时,表示两个动作同时进行。 Presentation 02 常见易混点辨析 过去进行时VS一般过去式: 过去进行时侧重动作“持续进行的过程”; 一般过去时侧重动作“已完成的结果”。 He read a book yesterday. ( 强调“读了”这个完成的动作。) He was reading a book at 3 p.m. yesterday. ( 强调“看书”这个持续的过程。) Practice 03 1 Complete the passage with the correct form of the verbs in brackets.
