The Third PeriodTeaching Aims:1.Review the new words appearing in the last periods.2.Learn to use the rules of word formation to guess the meaning of the word.Teaching Important Points:1.Learn to choose proper words according to the contexts of the given passage.2.Learn to guess the meaning of the words by the meaning of some stems and affixes.Teaching Difficult Points:1.Master the meanings of the following stems and affixes:mis-=wrongextra-=outsideinter-=betweensub-=underunder-=belowover-=too muchdis-=not-marine=sea2.How to guess the meanings of the words according to these stems and affixes.Teaching Methods:1.Review method to consolidate what weve learnt.2.Practice to make the students learn and master these stems and affixes,and then guess the meanings of the words using what theyve learnt.3.Individual,pair or group work to make every student work in class.Teaching Aids:1.the multimedia2.the blackboardTeaching Procedures:CStep GreetingsGreet the whole class as usual.CStep RevisionT:In the last period we learnt a passage about a French famous writer Jules Verne.Now,whod like to retell the text?(One student stands up and retells the text in his own words.)T:Very good.It seems that youve read the passage again and again.CStep Word StudyT:In the last period,we learnt some new words.Now,lets review them.Take a piece of paper and write down the words and phrases when I read them in Chinese.Are you ready?Ss:Yes.T:OK.Lets begin.(Teacher says the following words in Chinese and students write them down in English:collision,permanent,voyage,escape,on board,fiction,fantasy)T:If youve written them down,make a short sentence using every word.After a while,Ill ask some of you to read out your sentences.(A few minutes later)Have you finished?Ss:Yes.T:OK.Whod like to make a sentence using the first word “collision”?S1:The plane crashed after a collision with a tall building,killing all the passengers on board.T:Very good.Next word “permanent”.Who will try?S2:Love is a permanent topic for us all.S3:Next month,he is going to go on a voyage across the English Channel.S4:A thief robbed the young lady of her handbag and escaped.S5:All passengers on board are not from the same country.S6:He is fond of science fiction.S7:Not all fantasy can be realized in the future.T:Well done.Your sentences are very good.Now,please turn to Page 14 and finish the exercises in Word Study.First do it by yourself.Then check your answers in pairs.Finally Ill check your answers.Suggested answers:1.fantasy 2.voyage3.collision4.on board5.voyage6.collision7.on board8.escape9.fantasy10.permanentCStep Word FormationT:As we know,learning the rules of word formation is one of the ways to enlarge our vocabulary.We can guess the meanings of the words using them without looking them up in the dictionary.Please look at the screen.(Teacher shows the following on the screen.)rewrite,unhappy,disappear,impossible,invisible,non-smoker,supermarket,worker,illness,movement,useful,action,cooperate,cloudy,musicalT:What do the words mean?Explain how you guess them.Whod like to do the first one?S8:“Rewrite” means “write again”,because the prefix “re-” expresses “again”.Am I right?T:Right.Very good.S9:“Unhappy”“disappear” “impossible” “invisible” and “non-smoker” mean in turn “not happy” “not appear” “not possible” “not visible” and “people who dont smoke”.Because the prefixes “un-” “dis-” “im-” “in-” and “non-” all mean “not” and form the negative meanings of them.T:A good job!Lets go on.S10:“Supermarket” is made up of two parts:“super” and “market”.Market is a place where all kinds of things are sold,and “super” means “more than usual”.So “supermarket” means “超市” in Chinese.T:Youre right.Can you give some other examples?S10:Yes.For example,superman,superstar.T:Very good.Now,who knows the meaning of the word “cooperate”?S11:“Cooperate” is to say “work together”.Because “co-” means “together” or “with”.T:Do you agree with him/her?Ss:Yes.T:Thats right.Do you know the meanings of the rest words?Ss:Yes.(Students begin to say the meanings of them together.Then teacher asks one of them to explain them.)T:Wang Lin,tell me how you guess them.S12:These words have something in common.Their basic meanings dont change,and changes for them are just their parts of speech.For example “worker” is formed by adding “er” after “work”.It means “people who work”.So if we add “er” to a verb,a noun is formed.If we add “-ness” to an adjective,a noun is formed.After a verb,we can add “-tion” to form a noun,while after a noun,we need to add “-ful” “-al” or “-y” to form an adjective.Is that so?T:Quite right.In this class,well go on with some rules of word formation.(Teacher uses the multimedia to show the following.)mis-=wrongextra-=outsideinter-=betweensub-=underunder-=belowover-
