過去分詞作狀語_導學案

1、Unit3 Life in the future（導學案）Grammar 學習內容：過去分詞作狀語學習目標：掌握過去分詞作狀語的用法，并靈活運用學習重點：過去分詞作狀語的幾種情況學習難點：過去分詞與現在分詞及不定式作狀語的區(qū)別過去分詞短語作狀語，其邏輯主語通常是句子的主語，與主語關系是動賓關系，即被動關系。 過去分詞作狀語時的具體用法： 1過去分詞作時間狀語相當于一個時間狀語從句。例如： Asked (When he was asked) what had happened, he lowered his head. 當他被問問題的時候,他低下了頭。 2過去分詞作原因狀語相當于一個原因狀語從句

2、。例如： Frightened (=Because / As she was frightened) by the tiger, the girl didn't dare to sleep alone. 因為害怕老虎, 這個女孩不敢單獨睡覺。 3過去分詞作條件狀語相當于一個條件狀語從句。例如： Grown (If these seeds are grown) in rich soil, these seeds can grow fast. 如果種在肥沃的土壤里， 這些種子能長得很快。 Given (If we were given) more time, we could do it

3、better. 如果給我們更多時間的話，我們可以做得更好。 4過去分詞作讓步狀語相當于一個讓步狀語從句。例如： Left (Although he was left) at home, John didn't feel afraid at all. 雖然John被單獨留在房間里, 他一點都不害怕。 5 過去分詞作狀語表示伴隨動作或狀態(tài)。例如： The teacher entered the classroom, (and he was) followed by a group of students. 老師進入教室，后面跟著一幫學生。 1. 現在分詞與過去分詞作狀語的區(qū)別。現在分詞做狀

4、語與過去分詞做狀語的最主要區(qū)別在于兩者與所修飾的主語的主動與被動關系的區(qū)別。a.現在分詞作狀語時，現在分詞的動作就是句子主語的動作，它們之間的關系是主動關系。He went out shutting the door behind him.他出去后將門隨手關上。Not knowing what to do, he went to his parents for help.由于不知如何辦是好，他去找父母幫忙。b.過去分詞作狀語時，過去分詞表示的動作是句子主語承受的動作，它們之間的關系是被動關系。Given more attention, the trees could have grown be

5、tter.如果對這些樹多關心一些，它們本來會長得更好。Faced with difficulties, we must try to overcome them.在遇到困難的時候，我們必須設法克服。2. 動詞不定式和分詞作狀語的區(qū)別a.分詞作狀語一般表示伴隨，而不定式常常表示目的。They stood by the roadside talking about the plan他們站在路邊談論著這個計劃。(伴隨)They stood by the roadside to talk about the plan他們站在路邊為的是談論這個計劃。(目的)b.分詞作狀語放在句子開頭，除表示原因之外有時

6、表示時間或條件。動詞不定式作狀語時，除了表示目的以外，還表示結果或原因。Reading attentively，he forgot the time for lunch由于在專心讀書，他忘了吃午飯的時間。(原因)Reading carefully，he found something he had not known before他仔細讀書時，發(fā)現了一些從前不知道的東西。(時間)Reading carefully，you'll learn something new只要你仔細閱讀，你會學到一些新的東西。(條件)His family was too poor to support him

7、他的家庭太窮，不能維持他的生活。(結果)The boy is not tall enough to reach the book shelf這男孩個子不夠高，手伸不到書架。(結果)We are glad to hear the news我們很高興聽到這消息。(原因)高考練習：(   )1. _ more attention, the tree could have grown better. (90全國)     A

26、 a leader, an active person who enjoys life, people and excitement. Do you prefer grays(灰色)and blues? Then you are probably quiet, shy and you would rather follow than lead. If you love green, you are strong-minded and determined(意志堅定的). You wish to succeed and want other people to see you are succe

27、ssful. At least this is what psychologists(心理學家)tell us, and they should know, because they have been seriously studying the meaning of color preference(愛好), and the effect(影響)that colors have on human beings.

On the other hand, black is depressing(

29、壓抑). Light and bright colors make people not only happier but more active.

37、考答案：1-5 ADDC A6-10DCAB D11-15AAADA閱讀：BADCD改錯：1. Choose 改為 Choosing 。動名詞作主語2. have 改為has 。倒裝句中助動詞取決于后面的主語3.Tradition 改為Traditional 4.much 改為many 。calories 是calorie （卡路里）的復數5.better 后面的to去掉。 had better do sth 最好做某事6.choose 后面加from7.正確8.keep 改為keeping 。keeping 和前面的buying構成介詞in的賓語9.little

38、改為 less 。 less 和后面的more構成對應關系10.a去掉 。 health 是不可數， keep good health 保持身體健康過去分詞在英語學習中是較難掌握的語法知識，同時又是高考中的熱點之一。 過去分詞兼有動詞副詞和形容詞的特征。 過去分詞作狀語時，表示被動的或已完成的動作，在句中可作時間原因條件讓步方式伴隨狀語等。掌握過去分詞作狀語可從以下幾個方面考慮。 一理清過去分詞作狀語時與句子的主語的關系 1)過去分詞作狀語時，過去分詞與主句中的主語形成邏輯上的被動關系，有時也表示動作已完成。 例如： Seen in the dark night， lights on top

39、of tall buildings look like stars in the sky.(seen表示被動，分詞的動作與謂語動詞的動作同時發(fā)生) Scolded by the teacher， the girl began to cry. 被老師責怪，女孩哭了起來。(scolded表示被動且動作已完成) 【考例1】_ into use in April 2000， the hotline was meant for residents reporting water and heating supply breakdowns.(2005年上海卷) A. Put B. Putting C. H

40、aving put D. Being put 【解析】選A。主句主語the hotline與put into use邏輯上是被動關系，排除BC；D項表示正在進行的被動與句子意思不符。所以用過去分詞put短語作狀語。 2)有些過去分詞已經形成了系表結構，因此他們作狀語時與主句的主語之間是邏輯上的主動關系，但仍然用過去分詞形式。例如： Lost in thought， she nearly ran into a tree. 陷入沉思，她差點撞到樹上。 (lost意為“迷失的”，與邏輯主語連接起來相當于Because she was lost，作原因狀語)與lost類似的過去分詞還有disappoi

41、nted， dressed， determined， devoted， tired， exhausted， prepared， seated， caught等。 【考例2】After his journey from abroad， Richard Jones returned home， _. A. exhausted B. exhausting C. being exhausted D. having exhausted 【解析】選A。exhausted意為“筋疲力盡的”，由過去分詞演變成形容詞作伴隨狀語。 二注意過去分詞作狀語時在句中的位置 作狀語的過去分詞或短語可置于句子的前后或中間，

42、但是必須用逗號隔開以便與主句分開。 The PE teacher stood in the middle of the playground， surrounded by a group of students. 那位體育老師站在操場中間，被一群學生圍著。(過去分詞作伴隨狀語) 【考例1】 _ by the beauty of nature， the girl from London decided to spend another two days on the farm. (2004年遼寧卷) A. Attracting B. Attracted C. To be attracted D.

43、 Having attracted 【解析】選B。句子的主語the girl與attract是動賓關系或說是被動關系，所以要用過去分詞短語作狀語。 三掌握過去分詞作狀語與狀語從句的變換 過去分詞作狀語在功能上相當于狀語從句，在句中表示時間原因條件方式伴隨讓步等。所以經常會遇到過去分詞前帶有once， when， while， if， as if， even if， though， unless等連詞，我們將這種結構看成在連詞與過去分詞之間省略了與主句相同的主語和系動詞be。例如： Once published， this book will be popular with the studen

44、ts.=Once it is published， this book will be popular with the students.這本書一旦出版，它將會受到學生們的歡迎。(過去分詞作時間狀語。注：分詞前once可省略) 【考例1】_ with the size of the whole earth， the biggest ocean does not seem big at all. A. Compare B. When compared C. Comparing D. When comparing 【解析】選B。主句中的 the biggest ocean與compare形成邏輯

45、上的被動關系，因此要用過去分詞。 【考例2】No matter how frequently _， the works of Beethoven still attract people all over the world. (2006廣東卷) A. performed B. performing C. to be performed D. being performed 【解析】選A。動詞perform與句子的主語the works是動賓關系，故要選過去分詞performed，實際上相當于讓步狀語從句No matter how they are frequently performed，

46、。 四獨立主格結構 如果句中過去分詞的邏輯主語不是句子的主語，這時必須在過去分詞前加上主格的邏輯主語。這就叫作獨立主格結構。例如： The town seen from the hill， we can see it more clearly.=If the town is seen from the hill， we can see it more clearly. 如果從山上看這座城市，我們能看得更清楚。 Everything taken into consideration， the party was a success. 將所有的事情考慮在內，晚會算是成功的。 (taken的邏輯主語

47、不是the party， 所以添加其真正的主語everything) 【考例1】He sat silently， _. A. eyes are closed B. his eyes closing C. eyes closed D. eyes to close 【解析】選C。眼睛閉著表示伴隨狀態(tài)，如果只用過去分詞closed，則前后邏輯主語不一致，所以在其前面加上eyes作邏輯主語，eyes closed還可用介詞with引導，eyes closed=with his eyes closed。 1. Though _ of the danger， he still went skating on the thin ice. A. warning B. to warn C. warn D. warned2. _ from this point of view， the question will be of great importance. A. Considering B. Considered C. Being c
