一、現(xiàn)在分詞概說
1. 含義：現(xiàn)在分詞（Present Participle，又稱v-ing形式、現(xiàn)在進(jìn)行式) ，是分詞的一種。 它在句子里面不能單獨(dú)充當(dāng)謂語。但它具備v/n/adj./adv.的特征，因此能充當(dāng)其它 的一些成分（主語、賓語、表語、補(bǔ)語、定語和狀語）。
2. 特點(diǎn)：現(xiàn)在分詞表示主動(dòng)和進(jìn)行。
3. 現(xiàn)在分詞的形式：
V-ing有一般式和完成式。及物動(dòng)詞的-ing有主動(dòng)語態(tài)和被動(dòng)語態(tài)，而不及物動(dòng)詞的V-ing則沒有被動(dòng)語態(tài)?，F(xiàn)在以及物動(dòng)詞make 和不及物動(dòng)詞go為例，將其v-ing各種形式列表如下：
|
動(dòng)詞 語態(tài) 形式 |
及物動(dòng)詞make |
不及物動(dòng)詞go |
|
|
主動(dòng)語態(tài) |
被動(dòng)語態(tài) |
主動(dòng)語態(tài) |
|
|
一般式 |
making |
being made |
going |
|
完成式 |
having made |
having been made |
having gone |
注意： V-ing的否定形式是由not加V-ing構(gòu)成。如：
Not having heard the news. I wrote to him again.
Not knowing how to work out the math problem, I went to the teacher for help.
二、現(xiàn)在分詞的功能
1. 現(xiàn)在分詞作定語
1） 定語：修飾名詞或代詞
2） 定語從句：用一個(gè)句子來修飾名詞或代詞
3） 現(xiàn)在分詞作定語：用現(xiàn)在分詞來修飾名詞或代詞，分前置定語(位于所修飾詞的前面) 和后置定語（位于所修飾詞的后面）
4） 現(xiàn)在分詞短語作定語：用現(xiàn)在分詞短語修飾名詞或代詞，在意義上相當(dāng)于定語從句
練一練：（找出v-ing, 及所修飾的詞）
eg. She recognized the Tony’s smiling face.
句中 smiling 修飾 face, 在句中作 前置 定語
1. We were all nervous about the approaching examinations.
句中_____________修飾_____________,在句中作____________定語
2. He rushed into the burning house.
句中_____________修飾_____________,在句中作____________定語
3. The room facing south is our classroom.
句中_____________修飾_____________,在句中作____________定語
4. The factory making toys is run by neighborhood committee.
句中_____________修飾_____________,在句中作____________定語
5. The shaking building showed us that an earthquake was coming.
句中_____________修飾_____________,在句中作____________定語
2. 現(xiàn)在分詞作狀語
1） 狀語的功能：狀語說明地點(diǎn)、時(shí)間、原因、目的、結(jié)果、條件、方向、程度、方式和 伴隨狀況等。
2） 現(xiàn)在分詞短語作狀語：動(dòng)詞-ing形式作狀語可以修飾謂語動(dòng)詞或整個(gè)句子，在意義上 相當(dāng)于狀語從句
練一練：觀察下列句子中v-ing 作狀語的用法
1. Seeing (= When he saw ) a note on the ground, the stranger picked it up.
v-ing形式作 狀語， 相當(dāng)于一個(gè)時(shí)間狀語從句
2. Being late (= As he was late ) , he could not be allowed to join in the activity.
v-ing形式作 狀語， 相當(dāng)于一個(gè)原因狀語從句
3. Mr. Brown was killed in an accident, leaving (=and left) behind a wife and child.
v-ing形式作 狀語，表示一種必然的結(jié)果,常置于句末，可擴(kuò)展成一個(gè)含有并列 謂語的簡單句
4. The stranger was walking through the village, looking ( = and looked) this way and that.
v-ing形式作 狀語，其表示的動(dòng)作伴隨主句謂語動(dòng)作同時(shí)發(fā)生
5. Knowing ( = Although he knew ) all this , guard didn't let me enter the lecture hall.
v-ing形式作 狀語，相當(dāng)于一個(gè)讓步狀語從句
6. Working (= If you work ) harder, you will make great progress.
v-ing形式作 狀語，相當(dāng)于一個(gè)條件狀語從句
【課堂探究案】
使用方法&學(xué)習(xí)建議
探究案是在了解掌握基本概念的基礎(chǔ)上，研究v-ing在句中的用法及應(yīng)注意的問題。找出其中的規(guī)律并練習(xí)解決實(shí)際問題，以提高解題能力。
在課堂探究的過程中，請組成學(xué)習(xí)小組（4~6人/ 組），共同研究學(xué)案中所提出的問題，以預(yù)習(xí)學(xué)案中的概念為基礎(chǔ)，完成題目，找出規(guī)律并歸納總結(jié)。各小組選出發(fā)言人，負(fù)責(zé)在班級展示研究成果。
探究一：現(xiàn)在分詞的時(shí)態(tài)
v-ing在句中也有自己的時(shí)態(tài)變化，分別表達(dá)不同的含義。請觀察下列句子中v–ing 的時(shí)態(tài)變化及其含義。
1. Playing in the park, I met my friend Tom
2. Having finished the letter, he went to post it.
思考：
1. Playing (doing)是現(xiàn)在分詞的___________式；Having finished (having done)是現(xiàn)在分詞 的_____________式。
2. 現(xiàn)在分詞Playing 與 謂語動(dòng)詞met之間是否在時(shí)間上存在先后順序？
3. 現(xiàn)在分詞Having finished 與 謂語動(dòng)詞went 之間是否在時(shí)間上存在先后順序？
總結(jié)：doing 與 having done 之間的區(qū)別
練一練：
1. He got up late and hurried to his office, _________the breakfast untouched.
A.left B.to leave C.leaving D.having left
2. _____________ to reach them on the phone, we sent an email instead.
A. Fail B. Failed C. To fail D. Having failed
3. Last Sunday，my cousin sent me an e-mail ________me to his birthday party.
A. invited B. inviting C. to invite D. having invited
4. __________ his telephone number, we had to call his father first.
A. Not knowing B. Not having known C. Knowing not D. Having not known
探究二：現(xiàn)在分詞的語法性
分詞的特點(diǎn)是可以表達(dá)主動(dòng)和進(jìn)行，但是在一些句子中不但要表達(dá)進(jìn)行還要表達(dá)被動(dòng)。請回想預(yù)習(xí)案中分詞的被動(dòng)形式。
1. 分詞的語法性：指使用現(xiàn)在分詞的主動(dòng)式還是被動(dòng)式，主要取決于現(xiàn)在分詞和句子之間 的關(guān)系，句子的主語就是分詞的邏輯主語。
2. 邏輯主語：從語法上講，只有句子的謂語動(dòng)詞才有資格有自己的語法上的主語，就是我 們平時(shí)所說的主語。如果該動(dòng)詞作的不是謂語動(dòng)詞，那么，它的施動(dòng)者就不 能被稱為主語，只能被稱為邏輯主語。
觀察下列句子中v–ing 形式的用法
① Having been shown around the school, they were very happy.
② Having finished his homework, he went to bed.
思考：
在①句中，由having been shown構(gòu)成的分詞短語，與句子的主語_________存在________關(guān)系；在②句中，由having finished構(gòu)成的分詞短語，與句子的主語_________存在________關(guān)系。
總結(jié)：如何判斷分詞的語法性？
練一練：
1. The decision________, what is to be done now is how to carry it out.
A. is made B. has been made C. having been made D. having made
2. Look around when ________ the street.
A. cross B. crossing C. to cross D. crossed
3. _________many times, he finally understood it.
A. Tell B. Telling C. Having told D. Having been told
4. It rained heavily in the south, ________ serious flooding in several provinces.
A. caused B. having caused C. causing D. to cause
5. While watching television, ______.
A. the doorbell rang B. the doorbell rings
C. we heard the doorbell ring D. we heard the doorbell rings
探究三：現(xiàn)在分詞的解題步驟
在老師的引導(dǎo)下完成下列題目，注意老師的解題思路與步驟
1. The old man, ________abroad for twenty years, is on the way back to his motherland.
