Step 2 Revision
T：In the last period，we learned something about the terrible Tangshan Earthquake in 1976，which is the deadliest earthquake in China’s history.Now I am going to ask you some questions based on the Reading passage.
T：What did people in Tangshan see in the sky before the earthquake？
S1：They saw bright lights in the sky.
T：What did people hear？
S2：They heard the sound of planes outside Tangshan even when no planes were in the sky.
T：What did people notice in the wells？
S3：People noticed the well walls had deep cracks，and a smelly gas came out of the cracks.
T：Did people pay any attention to these abnormal phenomena？
S4：No.They went to bed as usual that night.
T：When did the earthquake begin？
S5：At 3：42 in the morning of July 28.
T：How many people were killed or injured in the quake？
S6：More than 400000 people.
T：Could the injured people go to hospital？
S7：No，they couldn’t because all of the city’s hospitals were gone in the quake.
T：Were there any aftershocks？
S8：Yes.Later that afternoon，another big quake shook Tangshan.Many rescue workers and doctors were trapped under the ruins.
T：Did the survivors deny the city and go to live in other places？
S9：No.They did the rescue work with the help of 150000 soldiers sent by the army.Slowly the city of Tangshan began to breathe again.
T：I am very satisfied with your work.
Step 3 Learning about Numbers
T：Maybe you have already noticed that there are a lot of numbers in the Reading passage.To read them correctly is very important.Sometimes there is a test on numbers in Listening.
T：Now turn to Page 28 and look at Part 3.Match each word to the number that has the same meaning.
（Allow Ss several minutes to finish the task.）
T：Now let’s check your answers.
S：A.90% ninety percent
B.10000 ten thousand
C.1000000 one million
D.150000 one hundred and fifty thousand
E.75% seventy-five percent
F.1/3 one-third
G.500 000 half a million
H.2/3 two-thirds
Step 4 Important points
T：In the Reading passage of this unit，there are some important words and expressions.I will first give you five minutes to pick out the difficult words，expressions and sentence patterns.You may work with your partner.

www.ff70.com （After five minutes.）
S1：In the first paragraph，“... the water pipes in some buildings cracked and burst.” How can we understand “burst”？
T：If something bursts or if you bursts it，it breaks open or apart suddenly and violently so that its contents come out.
e.g.You are going to burst the balloon，if you are not careful.
S2：In the first paragraph，“Farmers’ wives noticed that the well walls had deep cracks in them.” and in the second paragraph “A huge crack that was eight kilometers long and thirty meters wide.” Do the two “cracks” have the same meaning？
T：You are very careful.Yes，they have the same meaning.Both of them are nouns.“Crack” means a very narrow space between two things or two parts of something.“Crack” can also be a verb，meaning to break or make something break so that it gets one or more lines on its surface，as in the sentence “In the city，the water pipes in some buildings cracked and burst.”
e.g.She fell off her bike and cracked a bone in her leg.
S3：How can we understand this sentence in the second paragraph “It seemed that the world was at an end.”？
T：In order to understand this sentence，you have to know the meaning of the phrase “be at an end”.It refers to a situation in which something is finished or no longer existed.
e.g.The long hot summer was at last at an end.
Other examples are “come to an end”，“put an end to sth.”.
T：So now who can explain the sentence in our text？
S4：Let me have a try.The earthquake was so terrible that nearly everything was destroyed.So people thought it was the end of the world.
T：Excellent.And this sentence uses exaggeration.
S5：In the second paragraph，“In fifteen terrible seconds a large city lay in ruins.” Why don’t we use “ruin” instead of “ruins”？
T：“Ruin” can be an uncountable noun，which means a situation in which you have lost all your money，your social position，or the good opinion that people had about you.
e.g.With the collapse of grain prices，small farmers are on the brink of financial ruin.
While “ruins” means the part of a building that is left after the rest has been destroyed.
e.g.the ruins of a bombed-out office block
S6：In the second paragraph “Two-thirds of the people died or were injured during the earthquake.” Can we use “wound” to take the place of “injure”？
T：No.To injure someone means causing physical harm to someone，for example in an accident or an attack.To wound someone means injuring someone，especially by making a cut or hole in their skin using a knife，gun，etc.
e.g.（1）One of the players injured his knee and had to be carried off.
（2）Gunmen killed two people and wounded six others in an attack today.
S7：In the third paragraph “Everywhere they looked nearly everything was destroyed.” Can we use the word “ruin” to take the place of “destroy”？
T：No.“Destroy” means to damage something so badly that it no longer exists or cannot be repaired.If you “ruin” something good or useful，it then usually exists，but no longer has its good qualities or features.
e.g.（1）The school was completely destroyed in the big fire last night.
（2）Too much sugar can ruin your teeth.
S8：In the third paragraph，“People were shocked.”What’s the meaning of the sentence？
T：“Shock” here means to make someone feel very surprised and upset and unable to believe what has happened.
e.g.The murder of such a young child deeply shocked the whole community.
S9：So the sentence in our text means people were surprised.
T：Yes.But there is a slight difference between “shock” and “surprise”.If something is，comes as，or gives you a shock it is unexpected and often very bad.
e.g.It came as a great shock to hear she was leaving home.
But a surprise is something that is unexpected，but is not necessarily bad.
e.g.What a nice surprise! I didn’t even think you were in the country!
S10：In the third paragraph，“People began to wonder how long the disaster would last.” What does the word “last” mean in this sentence？Is it an adjective？
T：No，it is not an adjective but a verb.“Last” here means to continue for a particular length of time.
e.g.The hot weather lasted for the whole month of July.
As a verb，“last” could also mean to manage to remain in the same situation，even when this is difficult.
e.g.They won’t be able to last much longer without fresh supplies.
The word “last” can also be used as a linking verb.It means being enough for someone to use.

www.ff70.com e.g.We only had $50 to last us the rest of the month.
S11：In the last paragraph，“All hope was not lost.” What is the meaning of this sentence？
T：This sentence is a partial negative.It has the same meaning with “Not all hope was lost.”
e.g.（1）All the students do not agree to the plan.
（2）Not all the students agree to the plan.
These two sentences mean some of the students agree to the plan，but some don’t.
Step 5 Consolidation
T：Now after the explanations of the words，expressions and sentence patterns，let’s do some exercises.Please turn to Page 28 and look at Part 2 in Learning about Language.Complete the passage with some of the words in the text.
（After several minutes teacher asks one of the students to read the short passage.Correct any mistakes if there are any.）
Step 6 Homework
T：In order to master the usage of these words and expressions，please do some related exercises.Finish off the two parts in Using Words and Expressions on Page 63.
