对时态的理解
口诀：不同时间发生的事，对应不同的时态，时态不同意不同，动词形变来完成。
解读：不同的时间对应不同的时态，不同的时态是通过谓语动词的不同形式来表现。
和其他时态相比较，变化的只是动词谓语部分，其他成分没有发生变化。
新知讲解
过去进行时的时间：
⑴表示过去的具体时刻,如：at this time yesterday, at that time , this time last week, at seven the day before yesterday morning, at that moment, then;
(2)过去的一段时间：from 1 to four yesterday afternoon
(3)以when（当…的时候)连接的一般过去时的从句，
(4)when（在这时)连接的过去进行时的从句
(5)while（与…同时）连接的从句
现在进行时的概念：
口诀：过去时刻在进行，过去进行时行。
解读：过去进行时表示在过去某一时刻正在进行的动作。
新知讲解
现在进行时动词谓语的构成：
口诀：动词谓语最重要，be加ing别忘掉，
一是不要忘了be，二不忘记ing。
ing变化须仔细，直加双写去哑e。
be用was或者were，根据主语来选做，
I was，you用were，单数was复数were，
was / were 提前变疑问，was / were 后not变否定
解读：过去进行时的谓语构成，要写成 be +动词ing形式。
be 是原型，在进去进行时的句子中，用be的过去时的
两个儿子was 、 were。具体用法是I was，you用were，
单数was复数were， was / were 提前变疑问，
was / were 后not变否定
新知讲解
动词ing形式（现在分词）的构成：
口诀：ing变化需仔细，直加双写去哑e
解读：1、直加：一般在词尾直接加ing。
read---reading watch---watching draw---drawing
rain---raining snow---snowing speak---speaking
jump---jumping call---calling work---working
play---playing sing---singing
2、双写：一元，一辅 结尾，重（读音节）
swim---swimming skate---skating put---putting
sit---sitting run---running cut---cutting
3、去哑e（以不发音的字母e结尾的去e，加ing）
make---making take---taking write---writing have---having
come---coming skate---skating dance---dancing

四种情况特殊记，用好过去进行时要注意。
1、口诀：从过去到过去，动作一指在继续；
解读：过去一段时间内持续进行的动作，不涉及动作是不是完成。

新知讲解
典型示例
四种情况特殊记，用好过去进行时要注意
2、口诀：when连过去时从句，主句动作在继续，when的意思是当---时；
解读： when连接的从句意思是“当---时”，表示动作发生的时刻点，在这个时刻点主句动作正在进行。
例如：
①I was cooking when he knocked at the door.当他敲门的时候（表示一个时刻点）我在做饭。
②The students were reading when the teacher came into the classroom.当老师走进教室的时候（表示一个时刻点）同学们正在读书。
③He was washing clothes when I saw him.当我看到他的时候（表示一个时刻点）他正在洗衣服。
新知讲解
典型示例
四种情况特殊记，用好过去进行时要注意
3、口诀：主句一般过去时，when连过去进行时，when的意思是在这时；
解读：主句连接一般过去时的句子，是瞬间发生的动作，这时主句动作正在进行， when的意思是在这时。
例如：
①He knocked at the door when I was cooking when. 他敲门了，这时我在做饭。
②The teacher came into the classroom when the students were reading when. 老师走进了教室，这时同学们正在读书。
③I saw him when he was washing clothes when. 我看到他了，这时他正在洗衣服。
新知讲解
典型示例
四种情况特殊记，用好过去进行时要注意
4、口诀：while两动作都进行，过去进行时做行，while意思是与---同时。
解读：while连接的从句动作发生的同时，主句动作也正在进行。
例如：
(1)My mother was cooking while my father was reading.我的妈妈正在做饭与此同时我的爸爸在读书。
(2)Tom is singing while Jim is dancing.Tom在唱歌，与此同时Jim在跳舞
(3)While he was waiting for the bus, he was reading a newspaper.他边等车边看报。 (两个动作都是延续的)
(4)He was cleaning his car while I was cooking. 他擦车时我在做饭。(两个动作同时进行)
。
新知讲解
过去进行时句子的句式变换：
口诀： be若提前变疑问，be后not变否定 。
解读：在变成否定句时was / were的后
面加not，变疑问句时把was / were提前。
注意：把I was---. 要变成were you ----
把my变成your
新知讲解

对on the hill提问:Where were you planting trees at ten yesterday
对at ten划线提问：What time were you planting trees yesterday
对at ten yesterday划线提问：What time were you planting trees
典型示例
新知讲解
一般过去时与过去进行时的区别
一般过去时与过去进行时都可以和表示过去的时间状语如last night 等连用，但两者意思差别很大,这时一般过去时表示动作已经完成，而过去进行时表示在过去的某段时间里动作正在进行，动作不运一定完成。
例句：
①I wrote a letter last night.（昨天晚上我写了一封信——信已经写完）
I was writing a letter last night. (昨天晚上我在写了一封信——信不一定写完）
②We built a school last year (去年我们建了一所学校—— 学校已经建立起来了).
We were building a school last year.(去年我们在建学校——学校不一定建起来)
