16、rns.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 violently so that its contents come out.e.g.You are
17、 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 ver
18、y 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 wate
19、r 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 en

23、 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 in an accident or an attack.To wound someone means

25、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

28、e was leaving home.But a surprise is something that is unexpected，but is not necessarily bad.e.g.What a nice surprise! I didnt 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
29、 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 wont be able
30、 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.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 p
31、artial 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 dont.Step 5 ConsolidationT：Now after the explanations of the words，
