      中考英語句型轉(zhuǎn)換技巧

      陸海生供稿

      句型轉(zhuǎn)換是中考英語必考的重點(diǎn)題型之一。在歷年中考中,句型轉(zhuǎn)換題的分值占比一直挺大,而且有愈來愈高之勢。這種題型可以有效地幫助學(xué)生理解并鞏固所學(xué)的句型,掌握各種句型的內(nèi)在含義。學(xué)生如能掌握句型轉(zhuǎn)換的解題技巧,對他們理解并運(yùn)用所學(xué)句型、形成語感,進(jìn)而培養(yǎng)他們的英語綜合運(yùn)用能力有著極其重要的意義。在日常英語教學(xué)中,每位英語教師都十分重視對學(xué)生句型轉(zhuǎn)換解題技巧的培養(yǎng),因?yàn)樗麄兩钪喝绻麑W(xué)生掌握了句型轉(zhuǎn)換的本質(zhì)含義和解題技巧,那不僅能熟練地運(yùn)用各種句式和句型進(jìn)行口頭表達(dá),還能夠熟練地完成句型轉(zhuǎn)換題,把所學(xué)的句型和句式舉一反三、靈活運(yùn)用。這樣就把口頭運(yùn)用轉(zhuǎn)換成了筆頭運(yùn)用,從而培養(yǎng)了學(xué)生的綜合語言運(yùn)用能力。

      筆者在從事一線英語教學(xué)十余年的過程中,摸索出了一些句型轉(zhuǎn)換題的解題技巧,現(xiàn)結(jié)合句型轉(zhuǎn)換的常見題型作出如下歸納。

      一 由★肯★定★句★變★為★一★般★疑★問★句

      由肯定句變?yōu)橐话阋蓡柧涞囊?guī)則是把助動詞置于句子的主語之前。解題時(shí)應(yīng)把握以下幾點(diǎn):

      1/ 句子的謂語動詞如果是be動詞,則把be動詞直接提到主語前面。

      注在肯定句和一般疑問句中,主語的第一、二人稱要互換。

      1) We are in Class 1, Grade 7.

      ? Are you in Class 1, Grade 7?

      2) He’s polite and helpful.

      ? Is he polite and helpful?

      3) There are some birds in the big tall tree.? Are there any birds in the big tall tree?

      4) There are some Americans going to visit our school next week.? Are there any Americans going to visit your school next week? 5) A new modern bridge is being built over the Changjiang River.? Is a new modern bridge being built over the Changjiang River?

      2/ 句子的謂語動詞中如果有情態(tài)動詞,則把情態(tài)動詞直接提到主語前面。

      1) They can park their cars in front of the supermarket.

      ? Can they park their cars in front of the supermarket?

      2) I’d like some more dumplings.

      ? Would you like some more dumplings?

      3) Children must be kept away from fire.

      ? Must children be kept away from fire?

      3/ 句子的謂語動詞如果是現(xiàn)在完成時(shí)或過去完成時(shí),則把時(shí)態(tài)中的助動詞have、has或had提到主語前面。

      1) I have finished reading the interesting book.

      ? Have you finished reading the interesting book?

      2) The old woman had been dead before her daughter arrived.

      ? Had the old woman been dead before her daughter arrived?

      4/ 句子的謂語動詞如果是行為動詞的一般現(xiàn)在時(shí)或一般過去時(shí),那么在改為一般疑問句的時(shí)候,要根據(jù)主語的人稱和單復(fù)數(shù),添加助動詞do、does或did。

      1) We enjoy the football matches very much.

      ? Do you enjoy the football matches very much?

      2) Her mother does some cleaning every morning.

      ? Does her mother do any cleaning every morning?

      3) She went to see her doctor yesterday.

      ? Did she go to see her doctor yesterday?

      注在添加了助動詞的一般疑問句中,行為動詞一律為動詞原形。

      二 由★肯★定★句★變★為★否★定★句

      由肯定句變?yōu)榉穸ň涞囊?guī)則是在句中的助動詞后面添加否定詞not。如果句中謂語動詞的情況和上述的前三點(diǎn)相同,則直接在be動詞、情態(tài)動詞和have、has或had之后添加否定詞not。除了be動詞的am詞形外,否定詞not可以和助動詞縮寫為“助動詞 + n’t”。而如果句中的謂語動詞是行為動詞的一般現(xiàn)在時(shí)或一般過去時(shí),則要先添加助動詞do、does或did,再在其后添加否定詞not,分別可以縮寫為don’t、doesn’t和didn’t。

      注在行為動詞一般現(xiàn)在時(shí)和一般過去時(shí)的否定句中,行為動詞也一律為動詞原形。

      1) He is from England.

      ? He isn’t from England.

      2) They can look for things on the Internet in Computer lessons.

      ? They can’t look for things on the Internet in Computer lessons.

      3) I have seen the interesting film already.

      ? I haven’t seen the interesting film yet.

      4) His brother often plays football after school.

      ? His brother doesn’t often play football after school.

      5) My grandma came for dinner yesterday evening.

      ? My grandma didn’t come for dinner yesterday evening.

      注下面兩種句型在變?yōu)榉穸ň鋾r(shí)情況會特殊一些,做題時(shí)須引起重視:

      1) I think+賓語從句

      該句型在變?yōu)榉穸ň鋾r(shí),否定詞not應(yīng)放在主句上,即I don’t think+賓語從句。

      例I think it will rain tomorrow.

      ? I don’t think it will rain tomorrow.

      2) 祈使句

      祈使句的特征是沒有主語,以動詞原形開頭。在變?yōu)榉穸ň鋾r(shí),應(yīng)在動詞原形之前添加助動詞don’t。

      例Water the flowers.

      ? Don’t water the flowers.

      三 句★子★的★單★復(fù)★數(shù)★互★換

      句子單復(fù)數(shù)轉(zhuǎn)換的規(guī)則是:對應(yīng)句中的名詞、代詞和動詞,能變則變,不能變的,要么保留、要么去掉。要想做到熟練掌握并運(yùn)用這一規(guī)則,必須掌握名詞單復(fù)數(shù)的變化規(guī)則、代詞對應(yīng)的人稱和單復(fù)數(shù),以及動詞第三人稱單數(shù)的變化規(guī)則等。在解題過程中,還必須具體情況具體分析。

      1) The girl is from England.

      ? The girls are from England.

      2) He is a polite and helpful boy.

      ? They are polite and helpful boys.

      注對于“There be”句型,單復(fù)數(shù)轉(zhuǎn)換時(shí)句中的a/an不能去掉,要根據(jù)句式將其與some或any互換。

      1) There is a boat on the lake.

      ? There are some boats on the lake.

      2) There isn’t a tree behind the house.

      ? There aren’t any trees behind the house.

      3) Is there a pet dog in your home?

      ? Are there any pet dogs in your home?

      4) There aren’t any pictures on the wall of our classroom.

      ? There isn’t a picture on the wall of our classroom.

      四 同★義★句★轉(zhuǎn)★換

      同義句轉(zhuǎn)換就是將所給的句子換個(gè)說法。這一題型包含的內(nèi)容較多,且形式較雜,包括詞匯的同義轉(zhuǎn)換和句型的同義轉(zhuǎn)換。掌握該題型的解題技巧,可以很好地幫助學(xué)生理解、掌握所學(xué)的詞匯和句型的含義,并在此基礎(chǔ)上加以活用,對學(xué)生形成語言的綜合運(yùn)用能力有極大的幫助。要掌握該題型正確的解題方法,需要在日常的英語學(xué)習(xí)中不斷練習(xí)、歸納、積累。一般說來,同義句轉(zhuǎn)換主要有以下幾種形式:

      1/ 詞匯的同義轉(zhuǎn)換。詞匯的同義轉(zhuǎn)換主要有同義詞及近義詞的轉(zhuǎn)換、反義詞的轉(zhuǎn)換和同一個(gè)詞在不同句式中不同語序的轉(zhuǎn)換等。

      1) I spent 50 yuan on the coat.

      ?I paid 50 yuan for the coat.(同義詞的轉(zhuǎn)換)

      2) He likes playing football too.

      ?He also likes playing football.(近義詞的轉(zhuǎn)換)

      3) Millie sits behind Daniel.

      ?Daniel sits in front of Millie.(反義詞的轉(zhuǎn)換)

      4) They are all from America.

      ?All of them are from America.(詞序的轉(zhuǎn)換)

      2/ 句型的同義轉(zhuǎn)換。常見的句型同義轉(zhuǎn)換主要有以下幾種形式:簡單句與簡單句的互換、簡單句與祈使句的互換、復(fù)合句與簡單句的互換,以及復(fù)合句與復(fù)合句的互換等。例

      1) My favorite lesson is English.

      ?I like English best.(簡單句和簡單句的互換)

      2) It’s lunchtime.

      ?It’s time for lunch. / It’s time to have lunch.(同上)

      3) Let’s go boating.

      ?Shall we go boating??Why not go boating?

      ?What about going boating?(同上)

      4) I spend about half an hour reading English in the morning.

      ?It takes me about half an hour to read English in the morning.(同上)

      5) He is too young to go to school.

      ?He isn’t old enough to go to school.(同上)

      ?He is so young that he can’t go to school.(簡單句和復(fù)合句的互換)

      6) You can’t play basketball in the street.

      ?Don’t play basketball in the street.(簡單句和祈使句的互換)

      7) I went to bed after my mother came back last night.

      ?I didn’t go to bed until my mother came back last night.(復(fù)合句和復(fù)合句的互換)

      五 對★句★中★的★劃★線★部★分★提★問

      對句中的劃線部分提問是句型轉(zhuǎn)換題的重要組成部分。該題型的主旨是確定劃線部分在句中是什么成分,并將合適的疑問詞放在句首代替該部分而構(gòu)成特殊疑問句。解答該題型可使用“三步提問法”。具體步驟如下:

      1/ 先選擇一個(gè)合適的疑問詞。

      英語中主要的疑問詞有:what、who、whose、when、where、which、why、how、how old、how many、how much、how long、how often、how soon和how far等。疑問詞的確定要根據(jù)句中劃線部分所作的成分。上述疑問詞的用法主要為:

      what:用來詢問事物、人的姓名和職業(yè)。另外,和不同的詞在一起使用還可詢問具體的方面,如what time詢問時(shí)間,what color詢問顏色等;

      who:用來詢問人,尤其指人與人之間的關(guān)系;

      whose:用來詢問歸屬,即和人之間的所有關(guān)系;

      when:用來詢問時(shí)間,一般指較大的時(shí)間范圍(小范圍的時(shí)間可用what time);where:用來詢問地點(diǎn);

      which:用來詢問哪一個(gè),主要針對名詞的定語提問;

      why:用來詢問原因,標(biāo)志是because;

      how:用來詢問方式、程度;

      how old:用來詢問年齡;

      how many:用來詢問可數(shù)名詞的數(shù)量,其后要接名詞的復(fù)數(shù)形式;

      how much:用來詢問不可數(shù)名詞的數(shù)量,其后要接不可數(shù)名詞。如單獨(dú)使用則表示詢問多少錢或?qū)κ挛锏南矏鄢潭龋?/p>

      how long:用來詢問事物的長度,也可詢問時(shí)間的長度;

      how often:用來詢問某件事或某個(gè)動作在一定的時(shí)間范圍內(nèi)重復(fù)發(fā)生的次數(shù),即頻率;

      how soon:用來詢問某件事或某個(gè)動作從說話時(shí)起要過多久才會發(fā)生,即詢問將來的情況,一般與將來時(shí)態(tài)連用;

      how far:用來詢問空間距離。

      2/ 把原句變?yōu)橐话阋蓡柧洹?/p>

      3/ 把確定的疑問詞放在句首,其后跟上一般疑問句的語序,最后把劃線部分省略即可。

      注如果句中的劃線部分是主語或主語的定語,則可用疑問詞直接替換而不用一般疑問句的語序。

      例1) Her mother often gives her nice presents.

      本句中的Her mother在句中作主語,因而在確定了疑問詞who之后,不用將原句改為一般疑問句,直接替換即可。改寫后的句子為:“Who often gives her nice presents?”。

      2) The boy on the yellow bike is Lucy’s brother.

      本句中的on the yellow bike在句中作主語The boy的定語,限定是哪一個(gè)男孩,因而確定的疑問詞是which,直接替換后的句子為:“Which boy is Lucy’s brother?”。

      3) I spend about half an hour a day reading English.

      本句中的劃線部分既不是作主語,也不是作主語的定語,因而適用“三步提問法”。

      先確定疑問詞:about half an hour表示一個(gè)時(shí)間長度,因而疑問詞為how long;

      把原句改為一般疑問句:“Do you spend about half an hour a day reading English?”;

      把疑問詞how long放在句首,其后跟上一般疑問句,再把劃線部分去掉,最終的句子為:“How long do you spend a day reading English?”。
