Who have been helped by the new computer?誰已經(jīng)得到這種新計算機的幫助? Where has the car been repaired?這輛小汽車已經(jīng)在哪里修理好了? 現(xiàn) 在 完 成 時 被 動 語 態(tài) 的 主 要 用 法 1．表示被動的動作發(fā)生在說話之前（即現(xiàn)在的過去），強調(diào)對現(xiàn)在造成的影響和結(jié)果。 The door has been locked．門被鎖上了。（結(jié)果是現(xiàn)在沒有人能進去） Many of the world's greatest cities have been built on the banks of a river.世界上許多偉大的城市都是依河而建的。 St Petersburg has also been the center of many important events in history.圣彼得堡也是歷史上許多重大事件的中心。 2．表示一個被動的動作或狀態(tài)開始于過去，持續(xù)到現(xiàn)在，并可能將持續(xù)下去，常與for或since引導的時間狀語連用，或用于How long．．．？句型中。 They have been told about it for many times．有人告訴他們這事很多次了。（可能還會有人告訴他們） How long has the machine been used？這機器使用有多久了？ She hasn't been heard from since then.從那時候起，她就沒來過信。 使用現(xiàn)在完成時的被動語態(tài)需要注意的問題 1．現(xiàn)在完成時的被動語態(tài)有兩個助動詞，即 have ／has和been，兩者缺一不可。 This work has been finished, you may have a rest.這項工作已被完成，你可以休息一會兒。 This film has been put on for half an hour.這場電影已放映了半個小時。 2．注意與一般過去時被動語態(tài)的區(qū)別。 一般過去時的被動語態(tài)表示一個被動的動作發(fā)生在過去某個時候，其結(jié)果對現(xiàn)在沒有影響；而現(xiàn)在完成時被動語態(tài)的動作或狀態(tài)盡管發(fā)生在過去，但側(cè)重說明該動作或狀態(tài)對現(xiàn)在造成的影響和結(jié)果。例如： The house was built last year．這房子是去年建造的。 The house has been built．這房子已經(jīng)建好了。 3．由finish，buy，start，begin，post，return，borrow， join，marry，open等詞構(gòu)成的現(xiàn)在完成時的被動語態(tài)不能與表示一段時間的狀語如for four days，how long等連用，而要改換動詞或時態(tài)。 但這類動詞的否定式可表示動作的持續(xù)過程，具有延續(xù)性，因而可與since或for引導的時間段連用。例如： No books have been bought since last week．自上周以來，沒有人來買過書。 4．短語動詞是一個不可分割的整體，在被動結(jié)構(gòu)中要保持完整性，不可省略短語動詞中的介詞或副詞。 The orphan has been well looked after．這位孤兒一直受到很好的照顧。 【考題印證】 1.（2011天津卷,3）In the last few years thousands of films all over the world. have produced B. have been produced C. are producing D. are being produced 【解析】B考查動詞的時態(tài)和語態(tài)。句意為“在過去的幾年時間里，全世界制作了成千上萬部電影。”in the last few years在過去的幾年時間里，其實是從過去算到現(xiàn)在，是現(xiàn)在完成時的標志。選B。 2.（2010福建28）Every year a flood of farmers arrive in Shenzhen for the money-making jobs they before leaving their hometowns. A. promised B. were promised C. have promised D. have been promised 【解析】D現(xiàn)在完成時的被動語態(tài) 【真題體驗】 1.（2009福建，22） -Why does the Lake smell terrible? -Because large quantities of water .

At the time the accident happened, I'd done just 30 jumps. The airfield was quiet when I 1 . On board were Chris, who was taking a tourist, and Ants, the cameraman. Chris indicated I should exit first and the other three would 2 . Later I knew it was this 3 that saved my life. At 12,000 feet Chris rolled up the door and nodded that it was time for my exit. I put my foot on a step just beside the door, and in a(n) 4 the propeller blast (螺旋槳氣流) threw me against the 5 of the plane, half in, half out. I pushed and got my other leg out of the door, but in doing so I found myself 6 down the body of the plane towards the tail. My parachute (降落傘) got caught and my 7 and legs were pushed backwards, powerless, in the strong wind. I was strangely 8 . To a skydiver, being at 12,000 feet is a good thing. Altitude is your friend；being close to the ground is deadly and will kill you. Ants appeared and 9 slowly towards me, his legs held by Chris in the door. Ants reached out and got hold of my foot. With the weight partly off, I found myself falling away from the plane, 10 freed. I waved and smiled to indicate I was fine. It was actually very 11 . If any one of a number of factors had been different, I would have 12 . I could have hit the plane with my head. If I had been the last to exit, the pilot alone would have been unable to free me, and even if he had been aware that I was 13 underneath the plane, he would still have had to land at some point. Blue Skies, Black Death is the skydivers' mantra (咒語)．On the one hand, there's the freedom and 14 of the open sky. But in order to 15 this joy, you must accept that there is usually only one result if something goes wrong. 1． A. jumped B. arrived C. woke D. dove 2． A. follow B. escape C. leave D. fly 3.

A. observe B. experience C. imagine D. discover A The secret of carrier pigeons’ unbelievable ability to find their way home has been discovered by scientists; the feathered navigators follow the roads just like we do. Scientists now believe the phrase “as the crow flies” no longer means the shortest most direct route between two points. They say it is likely that crows and other birds also choose AA—suggested routes, even though it makes their journeys longer. Scientists at Oxford University spent 10 years studying homing pigeons using global positioning satellite(GPS) and got a surprising result. The birds often don’t use the sun to decide their directions. Instead they fly along motorways, turn at crossing and even go around roundabouts(繞道), adding miles to their journeys. “It really has knocked our research team sideways to find that after a decade-long international study, pigeons appear to ignore their inbuilt directional instincts(本能) and follow the road system,” said Prof Tim Guilford, reader in animal behavior at Oxford University’s Department of Zoology. Guilford said pigeons use their own navigational system(導航系統(tǒng)) when doing long distance trips or when a bird does a journey for the first time. “But once homing pigeons have flown a journey more than once, they can fly home on a habitual route, much as we do when we are driving or walking home from work,” said Guilford. “In short, it looks like it is mentally easier for a bird to fly down a road. They are just making their journey as simple as possible.” 1. What would be the best title of the passage? A. How Pigeons Find Their Ways Home B. Why Pigeons Can Fly Long Distance C. Birds Follow Roads As We Do D. Why Crows Fly the shortest Distance 2. Scientists used to think that homing pigeons often find their directions _______. A. by global positioning satellite B. by the sun C. by the road system D. by following other birds 3. Why do homing pigeons tend to follow the road system during their journey? A. Because they don’t have their inbuilt directional instincts now. B. Because their own navigational system doesn’t work. C. Because it is too hard to use their own navigational system. D. Because it is easier to make journey simple by following road system. B The word “conservation” has a thrifty meaning. To conserve is to save and protect, to leave what we ourselves enjoy in such a good condition that others may also share the enjoyment. Our forefathers had no idea that human population would increase faster than the supplies of raw materials: most of them, even until very recently, had the foolish idea that the treasures were “l(fā)imitless” and could “l(fā)ast forever”. Most of the citizens of earlier generations knew little or nothing about the complicated and delicate system that runs all through nature, and which means that, as in a living body, an unhealthy condition of one part will sooner or later be harmful to all the others. Fifty years ago, nature study was not part of the school work; scientific forestry was a new idea; wood was still cheap because it could be brought in any quantity from distant woodlands; soil destruction and river floods were not national problems; nobody had yet studied long-term climatic cycles in relation to proper land use; even the word “conservation” had nothing of the meaning that it has for us today. For the sake of ourselves and those who will come after us, we must now set about correcting the mistakes of our forefathers. Conservation should be made part of everybody’s daily life. To know about the water table in the ground is just as important to us as a knowledge of the basic math formulas. We need to know why all watersheds(上游集水區(qū)) need the protection of plant life and why the running current of streams and rivers must be made to give their full benefit to the soil before they finally escape to the sea. We need to be taught the duty of planting trees as well as of cutting them. We need to know the importance of big, grown trees, because living space for most of man’s fellow creatures on this planet is figured not only in square measure of surface but also in cubic(立方體的) volume above the earth. In a word, it should be our goal to restore as much of the original beauty of nature as we can. 4. The author’s attitude towards the use of natural resources is _________. A. positive B. uninterested C. optimistic D. critical 5. According to the author, the greatest mistake of our forefathers was that ________. A. they had no idea about scientific forestry B. they had little or no sense of environmental protection C. they were not aware of the importance of nature study D. they had no idea of how to make good use of raw materials 6. To avoid repeating the mistakes of our forefathers, the author suggests that _______. A. we plant more trees B. natural sciences be taught to everybody C. environmental education be directed toward everyone D. we return to nature 7. How can you understand the underlined sentence in the last paragraph? A. Our living space on the earth is getting smaller and smaller. B. Our living space should be measured in cubic volume. C. We need to take some measures to protect space. D. We must preserve good living conditions for both birds and animals. 單元自測答案： 第一節(jié) 1-5CDDAB6-10BAABA11-15BADBA 第二節(jié) 1-5: BADCD 6-10: ABDBD 11-15: DAACB 第三節(jié) 1-7ABDDBCD 111
