練習(xí)與體會(huì):
(綜合c級(jí)the barbie dolls)
barbie has undergone (經(jīng)歷)a lot of changes(變化) over the years and has managed (設(shè)法)to keep up with(與…保持一致) current (當(dāng)前的)時(shí)下的trends(趨勢) in hairstyles(發(fā)型), makeup(化妝) and clothing(服裝).

ⅴ、現(xiàn)在進(jìn)行時(shí)
1. 形式:
1) 現(xiàn)在進(jìn)行時(shí)由助動(dòng)詞am, is, are+現(xiàn)在分詞構(gòu)成。第一人稱單數(shù)用am,第三人稱單數(shù)用is,其他人稱一律用are。
2) 現(xiàn)在分詞由動(dòng)詞原形+ing構(gòu)成,如learning, making, stopping等。
 
2. 基本用法
1) 用在說話此刻正在進(jìn)行的動(dòng)作。
e.g. what are you doing here?
2) 表示現(xiàn)階段正在進(jìn)行的動(dòng)作,而說話此刻并不一定在進(jìn)行。
e.g. we are doing an experiment(實(shí)驗(yàn)) this month.(說話時(shí)不一定在做實(shí)驗(yàn))。
   
        3. 現(xiàn)在進(jìn)行時(shí)態(tài)的否定結(jié)構(gòu):
        e.g. we are doing an experiment this month. – we are not…
       
        4. 現(xiàn)在進(jìn)行時(shí)態(tài)的疑問句結(jié)構(gòu):
        e.g. we are doing an experiment this month. – are you doing…
 
提示:
能使用現(xiàn)在進(jìn)行時(shí)態(tài)的動(dòng)詞都是可持續(xù)的動(dòng)詞(如:read(讀), write(寫), listen(聽)),不可持續(xù)性的動(dòng)詞一般不能使用進(jìn)行時(shí)態(tài)。
比較:
e.g. he is dying(死).
e.g. the bus is coming(來).
 
考生要注意時(shí)態(tài)使用中的反常現(xiàn)象,如:
e.g. he is always(總是) sitting(坐)there(那里), crying(哭泣).
e.g. he is being nice(友善的).
 
練習(xí)與體會(huì):
(綜合a/b級(jí):importance of services)
these people argue(爭辯說) that manufacturing(制造業(yè)的) jobs, which (經(jīng)濟(jì)的) foundation (基礎(chǔ))of america’s middle class(中產(chǎn)階級(jí)), are vanishing(消失). they claim(聲稱) that factory(工廠) workers are being replaced(替代)with a host of (許多的)low-wage(低收入的) earners(掙錢者). have been the economic

ⅵ、過去將來時(shí)
由“shall或will的過去式should或would+動(dòng)詞原形”構(gòu)成。
表示在過去某一時(shí)刻之后將要發(fā)生的動(dòng)作或情況。 過去將來時(shí)態(tài)如果出現(xiàn)在從句中, 則主句謂語動(dòng)詞通常是是一般過去時(shí)。如:
e.g. we wanted(想要) to know (知道)when the english class would begin(開始).
 
過去將來時(shí)的否定和疑問結(jié)構(gòu):
it would be fine(晴朗的). 天氣會(huì)晴朗起來
it wouldn’t be fine.
would it be fine?
