the first sentence is?S1:I know.The Subject is “if/whether he will come.”And “It” is the formal Subject.T:Yes,youre right.(Bb:if/whether he will come.)And you must remember that if the Subject clause is put at the beginning of a sentence,we can only use “whether”.Are you clear?Ss:Yes.T:Good.Now,the second sentence.Who knows?S2:Let me try.“What we need” is the Subject.T:Good.Sit down,please.(Bb:What we need)Pay attention to the verb form in it.We know that if the Subject is a clause,we usually use a singular verb,but if the predicative is plural,we should use a plural verb.e.g.What we need are qualified teachers.Do you understand?Ss:Yes.T:And dont forget that if the Subject clause is introduced by “what” meaning “the thing or things that”,we dont use a formal Subject.OK?Ss:OK.T:Good.Now,lets look at the third sentence.S3:I think the Subject is “Finding somewhere to live in New York”.T:Right.Please sit down.(Bb:Finding somewhere to live in New York)Please pay attention to the verb in it.When the Subject means one action we should use a singular verb.When the Subject means two different actions,we should use a plural verb.Do you know?Ss:Yes.T:OK.Now,look at the fourth sentence.Whod like to have a try?S4:I think the Subject is “waiting here”.In this sentence,there is a formal subject “it”.T:Right.Sit down,please.(Bb:waiting here.)As you know,this is a very important sentence structure.(Bb:Its no use/good+v.-ing.)Are you clear?Ss:Yes.T:OK.And who can make a sentence using this sentence structure?S5:Let me try.“Its no good drinking too much.”T:Very good.Please sit down.(Bb:Its no good drinking too much.)Now,next sentence.Who wants a try?S6:Let me have a try.In this sentence,the Subject is “When to start”.T:Right.(Bb:When to start.)Can you say the Chinese meaning of the sentence?S6:Yes.It means “什么时候出发还没有决定呢”.T:Good.Please sit down.Look at the sixth sentence,please.Whats the Subject of this sentence?S7:The Subject is “To improve the working condition”.T:Right.(Bb:To improve the working condition)Can you say this sentence in another way?S7:Yes.We can say “It needs lots of money to improve the working condition”.T:Good.Sit down,please.And this sentence pattern is more common in modern English.So,youd better use this sentence pattern in your composition.Are you clear?Ss:Yes.T:Now look at the seventh sentence.Whod like to try?S8:Let me have a try.The Subject is “The unemployed”.T:(Bb:The unemployed)Good.In this sentence,you should pay attention to the verb form.If the Subject “the+v.-ed/adj.” referring to people,a plural verb should be used.If the Subject “the+v.-ed/adj.” referring to things,we should use a singular verb.Do you understand?Ss:Yes.T:Now look at the last sentence.Li Hua,you try,please.S9:The Subject is “Two million”.T:Right.(Bb:Two million)We should also pay attention to the verb form.If the numeral is used as the Subject,a singular verb should be used.When we make a sentence,we should pay attention to the agreement of the Subject with the Predicate.Do you understand?Ss:Yes.T:Then do you know the differences between the infinitive and the v.-ing form when they are used as the Subject?Any volunteers?OK.Wang Hua,please.S10:The infinitive used as the Subject expresses one particular occasion,while the v.-ing form used as the Subject expresses an activity in general.T:Quite right.Are you clear?Ss:Yes.Step Practice and ConsolidationT:OK.Weve reviewed some important points about the subject.And now,lets do some exercises to check if
