助動(dòng)詞have的用法,其豐富性與be不相上下。比如,助動(dòng)詞have+過(guò)去分詞,可以構(gòu)成完成時(shí)態(tài)。如:We've just done the washing-up./I have had this car for three years./By the end of last month, they had finished the work.

助動(dòng)詞have+been+現(xiàn)在分詞,可以構(gòu)成完成進(jìn)行時(shí)。如:I have been studying English for 8 years.(我學(xué)英語(yǔ)已達(dá)八年了。)The children have been having a lot of run.(孩子們一直玩得很開心。)

如果助動(dòng)詞have+been+現(xiàn)在分詞構(gòu)成的完成進(jìn)行時(shí),其動(dòng)作發(fā)生在過(guò)去,那么要記得把have變成had哦。比如:We had been doing business with each other for years before we quarreled.(在吵翻之前,我們多年來(lái)在業(yè)務(wù)上一直來(lái)往。)

想要使用完成式被動(dòng)語(yǔ)態(tài)時(shí),也可以用“have+been+過(guò)去分詞”。如:English has been taught in China for many years.(在中國(guó)英語(yǔ)教學(xué)已經(jīng)多年。)I have been made redundant, so I'm going abroad.(我被定成了超編人員,所以我打算出國(guó)。)

將來(lái)完成時(shí)的構(gòu)成是由“shall/will+have+過(guò)去分詞”構(gòu)成的。比如:By this time next year, we will have been doing business with each other for 20 years.(到明年這時(shí)候,我們的業(yè)務(wù)往來(lái)就滿20年了。)

英文俚語(yǔ)——go by the numbers
“按照順序”來(lái)是什么意思呢?這個(gè)短語(yǔ)其實(shí)是“循規(guī)蹈矩”的意思,它的典故是這樣的:有些商店顧客盈門,柜臺(tái)前排成長(zhǎng)龍,商店為了維持秩序就按照先來(lái)后到的次序,把寫有數(shù)字的票子發(fā)給排隊(duì)的顧客(現(xiàn)在我們稱為取號(hào)),以防止插隊(duì)和混亂。例如:I think you'd better start all over again with your report. Let's go by the numbers this time and follow our standard procedure.(你最好把報(bào)告重寫一遍,這次按照標(biāo)準(zhǔn)格式來(lái)寫。)
