      2015年職稱(chēng)英語(yǔ)考試知識(shí)解析:動(dòng)詞時(shí)態(tài)(3)

　　Ⅴ、現(xiàn)在進(jìn)行時(shí)(The Present Continuous Tense)

　　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(chēng)單數(shù)用am，第三人稱(chēng)單數(shù)用is，其他人稱(chēng)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

　　4) 用在此刻正在進(jìn)行的動(dòng)作。

　　e.g. What are you doing here?

　　5) 表示現(xiàn)階段正在進(jìn)行的動(dòng)作，而此刻并不一定在進(jìn)行。

　　e.g. We are doing an experiment this month..我們這個(gè)月在做一個(gè)實(shí)驗(yàn)(說(shuō)話(huà)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(wèn)句結(jié)構(gòu):

　　e.g. We are doing an experiment this month. ? Are you doing…

　　練習(xí)與體會(huì)：

　　(綜合A/B級(jí)：Importance of services)

　　These people argue that manufacturing jobs, which have been the economic foundation of America’s middle class, are vanishing. They claim that factory workers are being replaced with a host of low-wage earners.

　?、?、過(guò)去將來(lái)時(shí)

　　由“shall或will的過(guò)去式should或would+動(dòng)詞原形”構(gòu)成。

　　表示在過(guò)去某一時(shí)刻之后將要發(fā)生的動(dòng)作或情況。過(guò)去將來(lái)時(shí)態(tài)如果出現(xiàn)在從句中， 則主句謂語(yǔ)動(dòng)詞通常是是一般過(guò)去時(shí)。如：

　　e.g. We wanted to know when the English class would begin.

　　過(guò)去將來(lái)時(shí)的否定和疑問(wèn)結(jié)構(gòu)：

　　e.g. We would like to have some hamburgers.

　　e.g. We would not like to have some hamburgers.

　　e.g. Would you like to have some hamburgers?

　　(綜合A/B級(jí)：Plants and Mankind)

　　From then on humans would increasingly make their living from the controlled production of a few plants….

　　earn [get, make] one's living 謀生

　　Ⅶ、過(guò)去進(jìn)行時(shí)(the past continuous tense)

　　過(guò)去進(jìn)行時(shí)由“was (were)+現(xiàn)在分詞”構(gòu)成。

　　表示過(guò)去某一時(shí)刻或某階段正在進(jìn)行的動(dòng)作，通常帶有一個(gè)表示過(guò)去時(shí)間的狀語(yǔ)或時(shí)間狀語(yǔ)從句結(jié)構(gòu)

　　e.g. We were having a meeting at two thirty yesterday afternoon.

　　練習(xí)與體會(huì)：

　　(衛(wèi)生2002年C級(jí)閱讀理解考題：On the Train)

　　As he turned out his pocket to find enough money he saw the gentleman was watching him with amusement.. Donald realized that he was in quite an awkward situation, but the man was smiling.

　?、?、過(guò)去完成時(shí)(The Past Perfect Tense)

　　由"had+過(guò)去分詞"構(gòu)成該時(shí)態(tài)的謂語(yǔ),各人稱(chēng)都一樣。

　　表示在過(guò)去某一時(shí)刻或動(dòng)作之前已經(jīng)完成的動(dòng)作,這個(gè)到過(guò)去某一時(shí)刻為止的時(shí)間常用by, before等介詞或連詞引導(dǎo)的短語(yǔ)或從句以狀語(yǔ)形式來(lái)表示。

　　e.g. By the end of July last year, I had worked for forty years.

　　注意：

　　含有after, as soon as, before等連詞引導(dǎo)的狀語(yǔ)從句的復(fù)合句中，由于連詞本身已明確動(dòng)作發(fā)生的次序,所以,這個(gè)從句也可以用一般過(guò)去時(shí)表示，不用過(guò)去完成時(shí)。如：

　　e.g. Students went out after the bell rang. 鈴響后同學(xué)們出去了

　　e.g. I informed him of the progress of the work as soon as I arrived here

　　我一到這里就把工作進(jìn)程告訴了他。

　　The Cherokees refused to go. They had lived on their lands for centuries.

　　When the last group arrived in their new home in March 1839, more than 4,000 had died.

　　以下還有兩種時(shí)態(tài)偶爾我們也可能會(huì)在職稱(chēng)英語(yǔ)的文章中遇到：

　?、?、將來(lái)完成時(shí)(The Future Perfect Tense)

　　第一人稱(chēng):shall (will)+have+過(guò)去分詞

　　第二、三人稱(chēng):will + have+過(guò)去分詞

　　表示在將來(lái)某一時(shí)刻之前完成的動(dòng)作。如:

　　e.g. By this time next year they will have built a hotel here.

　　e.g. Hurry up! Or the train will have left before we get to the station.

　?、?、現(xiàn)在完成進(jìn)行時(shí)(The Present Perfect Continuous Tense)

　　第三人稱(chēng)單數(shù):has + been+ 現(xiàn)在分詞

　　其余人稱(chēng):have + been+ 現(xiàn)在分詞

　　表示從過(guò)去某一時(shí)間開(kāi)始,一直延續(xù)到現(xiàn)在的動(dòng)作,可能會(huì)繼續(xù)進(jìn)行下去或是到說(shuō)話(huà)時(shí)結(jié)束,但強(qiáng)調(diào)到說(shuō)話(huà)時(shí)為止一直在進(jìn)行的動(dòng)作。常與表示一段時(shí)間的狀語(yǔ)連用。如:for years, since early morning等。

　　e.g. They have been studying English for years.

　　e.g. He has been done English since early morning.

　　do: 處理;修理;收拾(房間等);洗;整(容);預(yù)備(功課);解答(問(wèn)題)
