英语语法简单学：过去进行时

英语语法简便学：已往举行时

【上期回忆】

英语语法简便学：如今举行时

【本期内容】

一、内容大纲

二、内容简述

（一）构成办法

该时态下，动词的情势是：was/were doing。此中，was/were是助动词，doing是如今分词。

（二）基本用法

1）表已往某个时候或时段正在举行的举措，如：

He was reading in the library this time yesterday.

昨天这个时分他正在图书馆看书。

She was working in the garden the whole after last Friday.

上周五整其中午她都在花圃里干活。

2）表委婉语气，如：

I was wondering if you can help me with my English.

不知你可否帮我向导一下英语。

3）表已往习气，此时常与频率副词连用，如：

He was always changing his mind.

他已往总是变想法。

（三）标志词

1）时候/时段+已往时间，如：

They were playing tennis in the gym from four to six yesterday afternoon.

昨天中午四点到六点，他们在体育馆打网球。

2）用于时间状语从句中，如：

When he came in, I was repairing my computer.

他过来时，我正修葺我的电脑。

3）含有whole或all等的已往时间，如：

Jack was helping his father all morning last Saturday.

上周六整个上午杰克都在帮他父亲。

I was preparing for the English test the whole day yesterday.

昨天一整天我都在准备英语测验。

（四）如今分词的厘革端正

1）直接+ing，如：working, playing

2）去e+ing（该动词以不发音的e开头），如：writing, making

3）双写最初一个辅音字母+ing（该动词以重读闭音节开头），如：stopping, beginning

4）不端正厘革，如：die - dying; panic - panicking

（五）句型厘革

原句：We were shopping at the mall the whole afternoon yesterday.

否定句：We were not shopping at the mall the whole afternoon yesterday.

寻常疑问句及其回复：

- Were you shopping at the mall the whole afternoon yesterday?

- Yes, we were.

- No, we weren't.

划线局部发问：

When were you shopping at the mall?

（六）特别情况

when与while引导时间状语时，其主从句的谓语动词的用法有所区别。when地点句子的主从句中的谓语动词既可以是刹时动词也可以是持续动词，但while地点的从句的谓语动词必需是持续动词或静态动词，但其主句的谓语动词既可以是刹时动词也可以是持续动词。如：

When he was walking into the dining room, he dropped some coins on the floor.

While he was walking into the dining room, he dropped some coins on the floor.

Whe he arrived, we were having dinner.

While we were having dinner, he arrived.
