Learning objectives
By the end of this section, you will be able to:

3. use context to understand new words during reading and apply them to complete some sentences;
4. grasp the features of a literary journalism, such as narrative structure, language after reading;
5. understand the theme of the text through answering some questions;
6. reflect on the lessons that we can learn from the earthquake.
Lead-in
Discuss what can happen to a city during a big earthquake.
A city can be damaged in an earthquake. The electricity can go down. The water can be unsafe to drink. Fires can start. People can panic or get severely injured.
Pre-reading
Look at the title and photo below and guess what the text is about. Then read and check if you are right.
THE NIGHT THE EARTH DIDN’T SLEEP
Maybe something terrible happened.
Maybe they wanted to rescue somebody under the collapsed buildings.
The earthquake that happened at night caused great damage to the city and people.
While-reading
Read the text carefully and then write down the main idea of each paragraph.
Paragraph 1: __________________________________________________
Paragraph 2: __________________________________________________
Paragraph 3: __________________________________________________
Paragraph 4: __________________________________________________
Paragraph 5: __________________________________________________
Warning signs before the earthquake.
The happening of the big earthquake.
The immediate effects of the earthquake.
The rescue work.
The revival of the city.
Scan the text and find the words below. Guess what they mean from the context.
Use context to understand new words
When you see a word you do not know, do not stop and look it up in a dictionary. If you continue reading, the context will probably help you understand what it means.
ruin brick trap bury
ruin
(noun, Paragraph 2)
This word describes the city straight after the earthquake. In a short time, a lot of damage was done, so it must describe a place that has been badly damaged.
brick
(noun, Paragraph 3)
This word is used to describe the buildings that have fallen. They are red like leaves, but also heavy, because the wind cannot move them. They sound like the red clay blocks commonly used to build buildings.
trap
(verb, Paragraph 4)
This verb is used to describe people who are not dead, but they need help to be dug out, so it must mean they cannot move because they are stuck somewhere.
bury
(verb, Paragraph 4)
This verb is used to describe what happens to the dead bodies. They are often put into the ground and covered, so that could be what this means.
Read paragraph 1 and answer the following questions.
1. What were some of the strange things that were happening before the earthquake
Before the earthquake, the water in the village wells rose and fell. Deep cracks appeared in their walls. Animals were acting strangely.
2. Do you think they were warning signs Why or why not
I think these were warning signs as this doesn’t usually happen and it showed something strange was happening below the ground. Sometimes, animals have more sensitive reactions to some coming dangers.
Read paragraphs 2&3 and answer the following questions.
1. When did the earthquake happen
At 3:42 a.m. on 28 July 1976.
2. What damage did it cause to the city and people
Nearly everything was destroyed and more than 400,000 people were killed or badly injured.
3. What happened later that afternoon
Another big quake shook Tangshan again.
4. How did people feel
They felt shocked and helpless.
Read paragraphs 4&5 and answer the following questions.
1. Who came to the rescue What did they do
150,000 soldiers. They were sent to dig out those who were trapped and bury the dead.
2. What does the writer mean by “Slowly, the city began to breathe again”
The writer means that the city began to function again, because the earthquake had stopped people and supplies moving about, and so it was like the city couldn’t breathe.
More than 10,000 doctors and nurses. They came to provide medical care.
Workers. They built shelters for survivors whose home has been destroyed
Read paragraphs 4&5 and answer the following questions.
3. What kind of help do you think people who have suffered an earthquake need
People in places who have suffered an earthquake need quick access to basic things such as water and food, because they cannot get them easily. They also need medical care, not just for injuries, but to protect against disease and other problems that happen after the earthquake. Last but not least, these people also need psychological care and help.
Read the sentences describing what happened after a huge plete the sentences with the correct forms of the new words and phrases from the text.

electricity
bricks

Work in groups. Discuss the questions.
1. What do you think helped in the revival of Tangshan city
I think the revival of Tangshan was helped by the strong support of the government and the people who all worked in unity to rebuild the city even better than before.
2. What other cities or towns have gone through similar changes What lessons can we learn from these events
Wenchuan county and some other towns near Wenchuan have the similar experiences. These towns were built up from the ruins. As well as developing better ways to detect and prepare for these disasters, we have learnt that acting quickly and in unity is the best way to get over such disasters. The strong support from government and people around are also very important.
Analyze the language features of the text.
1. Many sentences in the text give us a picture of the terrible earthquake in Tangshan. Which sentences impress you most Why
It seemed as if the world were coming to an end.
Bricks covered the ground like red autumn leaves.
Hard hills of rock became rivers of dirt.
The earth didn’t sleep.
The city began to breathe again.
simile

metaphor
personification
personification

Analyze the language features of the text.
2. Numbers are widely used in the text. Why does the writer mention so many numbers
Eleven kilometres directly below the city, one of the most deadly earthquakes of the 20th century had begun, a quake that even caused damage more than 150 kilometres away in Beijing. Nearly one third of the whole nation felt it!
Because numbers will give accurate information and make the description more convincing.

as if意为“似乎，好像”,可以引导表语从句和方式状语从句。其意义和用法与as though相同。
(1) 引导表语从句，常置于系动词look，seem，sound，feel，smell等之后。
Listen to the thunder! It seems as if it is going to rain. 听雷声！看来似乎要下雨了。

(3) as if/as though引导的从句的语气：
① 如果从句所表示的情况有明显的依据或实现的可能性较大，那么从句就用陈述语气；
② 如果从句所表示的情况没有依据，只是表达一种假设、愿望、怀疑或推测，那么就用虚拟语气。下表为表示虚拟的情况：
He talks as if he knew everything about it.
他讲起话来就好像关于此事他什么都知道似的。（与现在事实相反）
He went on working as if nothing had happened.
他继续工作，仿佛什么都没有发生。（与过去事实相反）
It seems as if the meeting would never end. 会议似乎永远也开不完。（与将来事实相反）
