Section A What happens during a natural disaster
(4a—4d)
Learning Objectives
In this lesson you will:
1. understand the form and function of the past continuous
tense.
2. differentiate the use of “when” and “while” in past
continuous tense.
3. apply the past continuous tense orally and in writing.
Read the sentences. Underline the verbs which show an ongoing action in the past.
4a
What were you doing while it was snowing heavily I was travelling on the train then.
What were your family doing when the typhoon hit My children and I were reading together.
When my neighbour called, my family were having dinner. We were driving home when the strong winds started. While we were driving home, the strong winds started. It was raining hard while we were driving back. Think and Discuss
What are the differences between when and while when used in past continuous tense
What were you doing while it was snowing heavily
What were your family doing when the typhoon hit
When my neighbour called, my family were having dinner.
While we were driving home, the strong winds started.
It was raining hard while we were driving back.
过去进行时的基本用法
过去进行时表示过去某个时刻或某一阶段正在进行的动作。
过去进行时表示在过去某个确定的时间点或某一段时间里正在发生的动作。
因此,原则上常和表示过去的时间状语连用。例如:then, at this/that time, yesterday, last night。
E.g. I was playing volleyball with my friends yesterday
afternoon.
I was doing my homework while my sister was watching TV last night.
有些情况下,句子中没有明确表示时间的状语,但从句
子的上下文中可以得知这是在过去某一时间内正在进行的动作。
E.g. We didn’t go shopping as it was raining heavily.
It was a very cold night and a terrible wind was blowing.
过去进行时中when和while的区别
when可以表示时间点,也可以表示时间段,后面既可以+延续性动词,也可以+非延续性动词,时态既可以是一般过去时,也可以是过去进行时。
E.g. I was sleeping when the doorbell rang.
When I was reading English words, my mother came in.
while仅表示时间段,引导表示过去的时间状语从句时,从句的动词必须是延续性动词,时态用过去进行时。
E.g. He fell asleep while he was watching TV.
The fire alarm went off while we were having a meeting.
主句(瞬间动作)+ while + 从句(持续动作)
当主句和从句都为过去进行时,只能用while引导,不能用when。
E.g. We were playing basketball while it was raining.
I was reading while she was writing.
主句(持续动作) + while + 从句(持续动作)
记忆口诀:
when后“可长可短”(过去进行时、一般现在时都可以)
while后“只能长”(只能用过去进行时)
两个动作都是“长动作”(过去进行时),用while
过去进行时的句型
肯定句
主语+be (was/were)+现在分词+其他
E.g. She was playing the piano when the bell rang.
When I came home, they were cooking in the kitchen.
否定句
主语+be(was/were)+not+现在分词+其他
E.g. He wasn’t reading when I came home.
When he knocked at the door, we weren’t doing our homework.
一般疑问句
Be (Was/Were)+主语+现在分词+其他
E.g. A: Were you cooking at that time
A: Was he singing then
B: Yes, he was. / No, he wasn’t.
B: Yes, I was. / No, I wasn’t.
特殊疑问句
疑问词+be (was/were)+主语+现在分词+其他
E.g. A: What was he doing when I called you
B: He was studying at the library.
A: What were you doing when the teacher came in
B: We were discussing the homework.
过去进行时和一般过去时的区别
一般过去时只表示一个完成的动作,而过去进行时表示过去某时正在进行的动作。也就是说,用一般过去时只是表示有过这件事;用过去进行时则强调了动作的连续性。
E.g. The children watched TV yesterday night.(只说明昨晚孩子们看过电视,但看了多长时间并不知道。)
The children were watching TV yesterday evening.(不仅陈述昨晚孩子们看电视这一事实,更强调他们看电视的时间贯穿昨晚整个时间段。)
4b
Combine each pair of sentences using when or while.
1. I did my homework. The typhoon landed on the coast.
I was doing my homework when the typhoon landed on the coast.
2. The power went out. My father and I made dinner.

3. Kate wrote a letter. Her brother called to warn her of the
storm.
Kate was writing a letter when her brother called to warn her of the storm.
4. My parents packed the supplies. I moved our things off the
floor.
My parents were packing the supplies while I was moving our things off the floor.

Storm Chasing: A Dangerous but Important Job
Are you afraid of big storms Many people are. But did you know some people go out to chase tornadoes Such storms can hit suddenly and move very quickly, so storm chasers always have to be prepared.
When a tornado is about to hit, professional storm chasers try and get close to it to collect important information. Storm chaser Tim Samaras designed and built many different instruments for studying tornadoes.
Throughout his career, the engineer chased down more than 120 tornadoes. Often, he filmed the storms while they were happening just a few kilometres away.
During a storm, storm chasers put special equipment in the way of the tornado. The equipment collects information about things such as wind speed and air pressure.This helps scientists to make better forecasts. It can even help people understand how powerful the winds can be, and as a result, change how we build our houses.
Storm chasing can be exciting, but also very dangerous. The storm chasers' knowledge and experience are not always enough to keep them safe. On 31 May 2013, Samaras and his team were chasing the El Reno tornado in Oklahoma, USA. To their surprise,the tornado behaved in an unexpected way. It grew rapidly and changed its speed and direction.
On that terrible day, the largest tornado ever recorded appeared. It was 4.2 kilometres wide and had winds topping 480 kilometres per hour. While the tornadowas moving towards them, Samaras and his team were driving as fast as they could. Sadly, when the tornado hit their car, it threw their car into the air like a toy. All three men in the car died.
The story of Tim Samaras is very sad, but his work continues to play an important role in weather science. Though storm chasing remains a dangerous job, the goal of storm chasers is to learn more about storms to keep people safe. For people like Samaras, that goal makes it all worth it.
