英語共有十六種時(shí)態(tài),其表現(xiàn)形式如下(以study為例)
一般時(shí) 進(jìn)行時(shí) 完成時(shí)完成進(jìn)行時(shí)
現(xiàn)在 study be studyinghave studied have been studying
過去 studied be studyinghad studied had been studying
將來 will study will be studying will have studied will have been studying
過去將來would study would be studying would have studied would have been studying
時(shí)態(tài)(Tense)是表示行為、動(dòng)作和狀態(tài)在各種時(shí)間條件下的動(dòng)詞形式。因此,當(dāng)我們說時(shí)態(tài)結(jié)構(gòu)的時(shí)候,指的是相應(yīng)時(shí)態(tài)下的動(dòng)詞形式。
1. 一般現(xiàn)在時(shí)
英語時(shí)態(tài)分為16種:一般現(xiàn)在、一般過去、一般將來、過去將來時(shí),以及這四者的進(jìn)行時(shí)、完成時(shí)和完成進(jìn)行時(shí)。
用法:A) 表示現(xiàn)在發(fā)生的動(dòng)作、情況、狀態(tài)和特征。
B) 習(xí)慣用語。
C) 經(jīng)常性、習(xí)慣性動(dòng)作。
例:He always helps others. (他總是幫助別人。)
D) 客觀事實(shí)和普遍真理。尤其要注意,如果前后文不是一般現(xiàn)在時(shí),則無法保持主句、從句時(shí)態(tài)一致。
E) 表示一個(gè)按規(guī)定、計(jì)劃或安排要發(fā)生的動(dòng)作,(僅限于某些表示“來、去、動(dòng)、停、開始、結(jié)束、繼續(xù)”等的動(dòng)詞)可以與表示未來時(shí)間的狀語搭配使用。常見的用法是:飛機(jī)、火車、輪船、汽車等定期定點(diǎn)運(yùn)行的交通方式。
例:The next train leaves at 3 oclock this afternoon.
(下一趟火車今天下午3點(diǎn)開車。)
How often does this shuttle bus run(這班車多久一趟?)
F) 在時(shí)間和條件狀語從句里經(jīng)常用一般現(xiàn)在(有時(shí)也用現(xiàn)在完成時(shí))表示將來事情。
例:When you have finished the report, I will have waited for about 3 hours.(等你完成這份報(bào)告的時(shí)候,我就已經(jīng)等了將近3個(gè)小時(shí)了。)
2. 現(xiàn)在進(jìn)行時(shí)(be doing)
用法:現(xiàn)在正在進(jìn)行的動(dòng)作。
3. 現(xiàn)在完成時(shí)(have done)
用法:A) 表示動(dòng)作到現(xiàn)在為止已經(jīng)完成或剛剛完成。
例:I bought a new house, but I _________ my old one yet, so at the moment I have two houses.
A) didnt sellB) soldC) havent soldD) would sell
答案是C) havent sold。
B) 表示從過去某時(shí)刻開始,持續(xù)到現(xiàn)在的動(dòng)作或情況,并且有可能會(huì)繼續(xù)延續(xù)下去。此時(shí)經(jīng)常用延續(xù)性動(dòng)詞。時(shí)間狀語常用since加一個(gè)過去的時(shí)間點(diǎn),或for加一段時(shí)間,或by加一個(gè)現(xiàn)在時(shí)間。
例:Great as Newton was, many of his ideas ___________ today andare being modified by the work of scientists of our time.
A) are to challenge C) have been challenged
B) may be challenged D) are challenging
全句的意思是:“雖然牛頓是個(gè)偉大的人物,但他的許多見解直到今天還在受到挑戰(zhàn),并且被現(xiàn)代科學(xué)家的工作所修正。”challenge是及物動(dòng)詞,在本句中應(yīng)當(dāng)是被動(dòng)語態(tài);其動(dòng)作延續(xù)到今天,所以要用現(xiàn)在完成時(shí)態(tài)。可見答案是C) have been challenged。A) are to challenge和D) are challenging都是主動(dòng)語態(tài),不可能是答案。B) may be challenged雖然是被動(dòng)語態(tài),但意思與全句內(nèi)容不合,所以不對(duì)。
C) 表示發(fā)生在過去,但對(duì)現(xiàn)在仍有影響的動(dòng)作或情況。通常用點(diǎn)動(dòng)詞,如:arrive, begin, find, give, lose等。
例:John has broken his left leg.(約翰摔斷了左腿。)
注意事項(xiàng):A) 現(xiàn)在完成時(shí)是聯(lián)系過去和現(xiàn)在的紐帶。現(xiàn)在完成時(shí)和過去時(shí)的區(qū)別在于:現(xiàn)在完成時(shí)強(qiáng)調(diào)動(dòng)作的動(dòng)態(tài),或受動(dòng)態(tài)的影響,是動(dòng)態(tài)的結(jié)果,對(duì)現(xiàn)在有影響;過去時(shí)只表示過去的某個(gè)具體時(shí)間里發(fā)生的動(dòng)作,與現(xiàn)在沒有聯(lián)系。
例:He worked in that hospital for 8 years.(他曾經(jīng)在那家醫(yī)院工作了8年。這只是講述一個(gè)過去的事實(shí),他現(xiàn)在已經(jīng)不在那家醫(yī)院了。)
He has worked in that hospital for 8 years.(他已經(jīng)在那家醫(yī)院里工作了8年。表示他從過去開始工作,一直工作到現(xiàn)在,現(xiàn)在仍在那家醫(yī)院工作。)
B) 因?yàn)楹衒or加一段時(shí)間或since加一個(gè)時(shí)間點(diǎn)這樣的時(shí)間狀語的完成時(shí),有動(dòng)態(tài)和延續(xù)性的特點(diǎn),所以不能使用終端動(dòng)詞或瞬間動(dòng)詞。
例:My sister has been married for 5 years.(過去分詞做表語表示狀態(tài),可以延續(xù))
My sister has married. Dont disturb her.(終端動(dòng)詞)
C) 在"this is the first/ second/ third…… time that……"句型里要求用完成時(shí)。
例:This is the second time that the products of our company have been shown in the International Exhibition.(這是我公司產(chǎn)品第二次參加國際展覽會(huì)。)
D) 句型"It is/ has been……since"所使用的兩種時(shí)態(tài)都正確。
例:It is/ has been 10 years since I last saw him.(從我上次見到他以來已經(jīng)10年了。)
E) 在"no sooner than"、"hardly/ scarcely ……when"、"before"、"prior to"等句型中,主句要求完成時(shí)。
例:I havent met that professor prior to today.(以前我從未見過那位教授。)4. 現(xiàn)在完成進(jìn)行時(shí)(have been doing)
用法:表示某一動(dòng)作開始于過去某一時(shí)間,延續(xù)或重復(fù)地出現(xiàn)至今,或?qū)⒗^續(xù)延續(xù)至將來。
例:We have been working on this project for over a month now.(到目前為止,我們一直在處理那個(gè)項(xiàng)目,已經(jīng)花了一個(gè)多月時(shí)間了。)
注意事項(xiàng):與現(xiàn)在完成時(shí)相比,現(xiàn)在完成進(jìn)行時(shí)更強(qiáng)調(diào):在從過去到現(xiàn)在的時(shí)間里,動(dòng)作或狀態(tài)一直持續(xù)或一直反復(fù)出現(xiàn)。
例:It seems oil ___________ from this pipe for some time. Well have to take the machine apart to put it right.
A) had leaked B) is leaking
C) leakedD) has been leaking
從本題上下文看,這兩個(gè)句子的意思是:“看來,這個(gè)管道漏油已有一段時(shí)間了,我們將不得不拆卸機(jī)器排除故障。”第二句表示將要采取的措施。第一句動(dòng)作發(fā)生在第二句之前,并且延續(xù)到現(xiàn)在為止仍在繼續(xù)。因此,空格中需用現(xiàn)在完成時(shí)或現(xiàn)在完成進(jìn)行時(shí)。D) has been leaking是現(xiàn)在完成進(jìn)行時(shí),因此是本題的答案。有11%的考生誤選了B) is leaking。由于本句有時(shí)間狀語for some time,表示謂語動(dòng)作延續(xù),謂語不能用現(xiàn)在進(jìn)行時(shí),必須用和完成時(shí)有關(guān)的時(shí)態(tài)。有些考生誤選了C) leaked或A) had leaked。是因?yàn)樗麄儧]有注意到本題第二句是一般將來時(shí),所以第一句的謂語不能用過去時(shí)或過去完成時(shí)。
5. 一般過去時(shí)
用法:A) 表示過去某個(gè)時(shí)間發(fā)生的動(dòng)作或情況。
B) 表示過去習(xí)慣性動(dòng)作。特別是由would/ used to do表達(dá)的句型,本身表示的就是過去時(shí)。例:The old man would sit on a bench in the quiet park and look at others for hours without doing anything or talking to anybody.(老人過去常常坐在寧靜的公園里的一條長椅上,看著其他的人,一坐就是數(shù)個(gè)小時(shí),什么也不干,也不和任何人交談。)
He used to visit his mother once a week.(他以前總是每周看望一次他的母親。)
C) 有時(shí)可代替一般現(xiàn)在時(shí),表達(dá)一種婉轉(zhuǎn)、客氣、禮貌、商量的語氣。
例:I wanted to ask you if I could borrow your car(我想向您借車用一用,可以嗎?)
Would you mind my sitting here(您介意我坐在這里嗎)
注意事項(xiàng):A) 注意時(shí)間狀語的搭配。一般過去時(shí)的時(shí)間狀語應(yīng)該是表示過去某個(gè)時(shí)間的詞或詞組,如:yesterday, last month, in 1999, two days ago等,絕對(duì)不可與recently, in the past 10 years, this month等連用,因?yàn)檫@樣的時(shí)間狀語都與現(xiàn)在有關(guān)系,應(yīng)該用現(xiàn)在完成時(shí)或一般現(xiàn)在時(shí)。
