39、the difficult words，expressions and sentence patterns.You may work with your partner.（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 v
40、iolently 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 th

42、ts 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
43、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
44、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 dont we use “ruin” instead of “ruins”？T：“Ru
45、in” 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 le
46、ft after the rest has been destroyed.e.g.the ruins of a bombed-out office blockS6：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

48、aph “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
49、 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.”Whats 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 mea
