Step Ⅲ Word Study

T:In the last period,we learnt some new words.Now,let’s 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.

上海龙凤1314T:OK.Let’s 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 you’ve written them down,make a short sentence using every word.After a while,I’ll ask some of you to read out your sentences.(A few minutes later)Have you finished?

Ss:Yes.

T:OK.Who’d like to make a sentence using the first word “collision”?

上海龙凤1314S1: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.

上海龙凤1314S3:Next month,he is going to go on a voyage across the English Channel.

Step Ⅳ Word Formation

T: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.

上海龙凤1314(Teacher shows the following on the screen.)

上海龙凤1314rewrite,unhappy,disappear,impossible,invisible,non-smoker,supermarket,worker,illness,movement,useful,action,cooperate,cloudy,musical

T:What do the words mean?Explain how you guess them.Who’d 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 don’t smoke”.Because the prefixes “un-” “dis-” “im-” “in-” and “non-” all mean “not” and form the negative meanings of them.

上海龙凤1314T:A good job!Let’s 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:You’re 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”?

上海龙凤1314S11:“Cooperate” is to say “work together”.Because “co-” means “together” or “with”.

上海龙凤1314T:Do you agree with him/her?

Ss:Yes.

上海龙凤1314T:That’s 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.

上海龙凤1314S12:These words have something in common.Their basic meanings don’t 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,we’ll go on with some rules of word formation.

上海龙凤1314(Teacher uses the multimedia to show the following.)

mis-=wrong

extra-=outside

上海龙凤1314inter-=between

sub-=under

under-=below

over-=too much

dis-=not

-marine=sea

T:Please look at the screen.Study the meanings of these stems and affixes in pairs and then try to give some examples with the stems and affixes.(A few minutes later)Are you ready?(Ss:Yes.)Now,I’ll ask some students to read out the words they’ve written.Any volunteer?

上海龙凤1314S13:Misconduct, extraordinary, international, subsoil,underground, overcharge, disagree, submarine.

(Teacher writes these words on the blackboard.)

T:Terrific!Do you understand the meaning of each word on the blackboard?

上海龙凤1314(Not all the students understand them.)

T:S13,can you explain them?

上海龙凤1314S13:“Misconduct” means “improper behaviour”.“Extraordinary” means “beyond what is usual or ordinary”.“International” is to say “between nations”.“Subsoil” is to say “layer of soil that lies beneath the surface layer”.“Underground” means “under the surface of the ground”.“Overcharge” means “charge(sb.) too high a price”.“Disagree” means “not agree”.“Submarine” means “a ship that can travel below the surface of the sea”.

T:Is that clear?(Ss:Yes.)Now,let’s do an exercise.Open your books and turn to Page 12.Look at Word Study,Exercise 1.Match the words and the correct definitions.I’ll give you two minutes to do it,and then I’ll check your answers.
