七年級(jí)英語怎樣句型轉(zhuǎn)換

時(shí)間: 桂香1115 分享

  在七年級(jí)的英語中,句型轉(zhuǎn)換也是一個(gè)重要知識(shí),那么七年級(jí)英語怎樣句型轉(zhuǎn)換呢?下面是學(xué)習(xí)啦小編為你整理的七年級(jí)英語句型轉(zhuǎn)換的方法,希望大家喜歡!

  七年級(jí)英語句型轉(zhuǎn)換的方法

  單數(shù)句與復(fù)數(shù)句相互改寫

  將句子改為復(fù)數(shù)句或單數(shù)句的關(guān)鍵是“牽一發(fā)而動(dòng)全身”,要注意人稱代詞和物主代詞的單復(fù)數(shù)的相互轉(zhuǎn)化,動(dòng)詞的原形和第三人稱單數(shù)的相互轉(zhuǎn)化,名詞以及量詞的單復(fù)數(shù)的相互轉(zhuǎn)化。這就要求同學(xué)們對(duì)相關(guān)知識(shí)要熟練掌握。

  例如:She has a tennis racket. 改成復(fù)數(shù)句為:They have some tennis rackets.。由此能夠看出主語變了,其后的動(dòng)詞也變了,一個(gè)網(wǎng)球拍變成了一些網(wǎng)球拍。Those are backpacks.改成單數(shù)句為:That is a backpack.。

  改為一般疑問句

  將陳述句改為一般疑問句分兩種情況。第一種是句子中含有be動(dòng)詞(常見的有am,is,are)。這種情況只需把be動(dòng)詞提到句首,將句號(hào)變?yōu)閱柼?hào)即可。特別注意:如果陳述句中主語是第一人稱的I,那么在變?yōu)橐话阋蓡柧鋾r(shí)將其變?yōu)榈诙朔Q,同時(shí)其所對(duì)應(yīng)的be動(dòng)詞也要跟著改變。例如:I am a teacher.變?yōu)橐话阋蓡柧鋺?yīng)該為Are you a teacher?。

  第二種情況是句子中不含be動(dòng)詞。在這類陳述句中要借助于do 或does,do和does 的選擇是根據(jù)句子主語的人稱和數(shù)來定的:

  (1)當(dāng)主語為第三人稱單數(shù)形式或不可數(shù)名詞的時(shí)候,用does;

  (2)主語為第一人稱、第二人稱,以及表示復(fù)數(shù)意義的詞做主語時(shí),用do。

  (3)另外還可以根據(jù)陳述句中的動(dòng)詞是否為第三人稱單數(shù)形式來判斷。例如:1) Tim has a good watch.變?yōu)橐话阋蓡柧錇镈oes Tim have a good watch? 2) Tom and Jerry like playing football 變?yōu)橐话阋蓡柧錇?Do Tom and Jerry like playing basketball?

  一些題目要求改寫句子之后做相應(yīng)的回答,只要一般疑問句改寫正確之后,相應(yīng)的回答也就迎刃而解了。

  肯定句與否定句相互改寫

  肯定句的改寫和否定句的改寫是一個(gè)互逆的過程。改寫為否定句,要看句子中是否有be動(dòng)詞。有be動(dòng)詞的,在be動(dòng)詞后加not;沒有be動(dòng)詞的,在動(dòng)詞前加don’t 或doesn’t。don’t 和doesn’t的選擇與一般疑問句中do或does 的選擇方法是相同的。切記,如果動(dòng)詞前用了doesn’t,那么這個(gè)動(dòng)詞不能要從三單形式變?yōu)樵?。例如?Mary likes healthy food. 變?yōu)榉穸ň錇?Mary doesn’t like healthy food.。

  改為肯定句的時(shí)候,要注意把doesn’t去掉之后動(dòng)詞要變成第三人稱單數(shù)形式。例如:Tony doesn’t like vegetables.變?yōu)榭隙ň錇?Tony likes vegetables.。

  對(duì)劃線部分進(jìn)行提問

  對(duì)劃線部分提問這類題型最重要的是確定特殊疑問詞,由此我們也就知道對(duì)劃線部分提問其實(shí)就是把所給句子變成特殊疑問句(特殊疑問詞+一般疑問句)。

  我們目前經(jīng)常用到的特殊疑問詞有:what(對(duì)事物提問)、why(對(duì)原因提問)、who(對(duì)人提問)、when(對(duì)時(shí)間提問)、how(對(duì)狀況和方式提問)、how old(對(duì)年齡提問)、how much(對(duì)價(jià)格提問)、where(對(duì)地點(diǎn)提問)。準(zhǔn)確把握劃線部分所對(duì)應(yīng)的特殊疑問詞之后,再加上一般疑問句形式,這種題型就解決了。

  例如:My favorite subject is science.(對(duì)劃線部分提問),science 屬于事物,所以特殊疑問詞確定為what;原句變?yōu)橐话阋蓡柧渲鬄镮s your favorite subject science?,What替代了science放到句子最前面,最終變?yōu)閃hat is your favorite subject?。

  同義句改寫

  同義句的改寫其實(shí)就是同樣的意思用不同的方式來表達(dá)。例如:My favorite subject is math. 它的同義句為I like math best. 注意:Someone’s favorite ….. is ….. 與….like….best 進(jìn)行同義轉(zhuǎn)換的時(shí)候要注意選擇上義詞。例如:He likes ice cream best. 同義替換為 His favorite food is ice cream.

  合并句子

  合并句子的實(shí)質(zhì)就是概括句子。例如:This is my father. This is my mother. 在這兩個(gè)句子中,這個(gè)加這個(gè)就是這些,mother和father就是父母,所以將這兩句話合并到一起就是These are my parents. 另外一個(gè)例子: She is my daughter. He is my son 這兩句話合并到一起就是 They are my children.

  英語句型轉(zhuǎn)換學(xué)習(xí)方法

  肯定句改否定句的方法 :

  1、 在be動(dòng)詞后加not。如:is not , are not , am not, was not, were not;

  2、 在can,should, will等后加not。如:cannot, should not, will not;

  3、 上述都沒有的,在動(dòng)詞前加助動(dòng)詞否定形式don’t/doesn’t/didn’t。

  4、 some 改成any。

  如: I am a girl. → I am not a girl.

  You are a student. →You are not a student.

  →You aren’t a student.

  This is Tom’s bag, → This is not Tom’s bag.

  → This isn’t Tom’s bag.

  答題方法是;否定詞not在be后邊。

  肯定句改一般疑問句的方法:

  1、 把be動(dòng)詞放在句首,剩下的照抄,(some 改成any,I改成you,my改成your,)句點(diǎn)改成問號(hào)。

  2、 把can,shall, will等放到句首,剩下的照抄,(some 改成any,I改成you,my改成your,)句點(diǎn)改成問號(hào)。

  3、 上述都沒有的,在句首請(qǐng)助動(dòng)詞Do/Does/Did幫忙,剩下的照抄,(some 改成any,I改成you,my改成your,)句點(diǎn)改成問號(hào)。

  注意:句首的第一個(gè)字母要大寫,句尾標(biāo)點(diǎn)應(yīng)為“?”。

  如:

  I am in Class 6. →Are you in Class 6?

  You are from America. →Are you from America?

  It is an orange. →Is it an orange?

  答題方法是:要想提問,be提前,句末“?”別忘了。

  4、 就一般疑問句回答

  一般疑問句有兩種回答,即:肯定回答和否定回答。其中,肯定回答用yes,否定回答用no。 語句順序?yàn)椋篩es + 主語 + am /is/ are/was/were.|can.|do/does/did|; No + 主語+ am not/ isn’t/ aren’t/wasn't/weren't.|can't.|don't/doesn't/didn't|.。如:

  —Are you an English teacher?→Yes, I am. /No, I am not.

  —Is that a bird? →Yes, it is./ No, it isn’t.

  對(duì)劃線部分提問

  “就劃線部分提問”是小學(xué)階段英語學(xué)習(xí)的難點(diǎn),但是一旦掌握了規(guī)律,就變得容易多了。 小學(xué)英語對(duì)劃線部分提問之答題口訣 :

  一代:用正確的疑問詞代替劃線部分。

  二移:把疑問詞移至句首

  三倒:顛倒主謂語,但對(duì)主語或其定語提問時(shí)除外(some 改成any,I改成you,my改成your),

  四抄:照抄句子剩余部分。

  ☆總結(jié)關(guān)鍵就是:“特殊疑問詞+一般疑問句”(即: 先根據(jù)劃線部分找到特殊疑問詞; 再把沒劃線的部分變成一般疑問句的語序。)

  ★特殊疑問詞的確定要根據(jù)劃線內(nèi)容而定,在小學(xué)階段常出現(xiàn)的有以下幾種:

  1.劃線部分是“事或物”,特殊疑問詞用what

  如: This is a book.

  ---What is this?

  I often play football on Saturdays .

  ---What do you often do on Saturdays ?

  2.劃線部分是“人”,特殊疑問詞用who

  如:He is my brother. ---Who is he ?

  3、劃線部分是“地點(diǎn)”,特殊疑問詞用where

  如:The box is on the desk.---Where is the box ?

  4、劃線部分是“時(shí)間”,特殊疑問詞用what time或when

  如:It's seven twenty . ---What time is it ?

  I usually get up at six . --- When do you usually get up?

  5、劃線部分是“年齡”,特殊疑問詞用how old

  如:I am twelve . ---How old are you?

  My father is thirty-three . ---How old is your father ?

  6、劃線部分是“職業(yè)”,特殊疑問詞用what

  如:Mike is a worker. ---What is Mike ?

  7、劃線部分是“顏色”,特殊疑問詞用what colour

  如: My hat is blue . ---What colour is your hat?

  8. 劃線部分是“數(shù)量”,特殊疑問詞用how many或how much

  如:I can see five kites .---How many kites can you see ?

  There is some milk in the glass. ---How much milk is there in the glass ?

  9、劃線部分是“多少錢”,特殊疑問詞用how much

  如:This pen is nine yuan . ---How much is this pen ?

  10、劃線部分是“形容詞性物主代詞或名詞性物主代詞”,特殊疑問詞用whose

  如:That is my book . ---Whose book is that ?

  The bag is yours. ---Whose is the bag ?

  同義句型轉(zhuǎn)換

  同義句型轉(zhuǎn)換,是把意思相同或相近的句子用不同的詞匯、短語及句型表示出來。如:

  I’m Peter. → My name is Peter.

  Tom is tall. →Tom isn’t short.

  I‘m fine. →I'm all right.

  我們現(xiàn)在學(xué)過的大多數(shù)句型,在一般情況下(就是不排除有特殊情況)都可以用簡單的公式來記憶。

  1.肯定句變否定句

  1) 主語+be動(dòng)詞+….

  *I am a teacher.→ I am not a teacher.

  He is a doctor. → He is not a doctor.

  They are students. →They’re not students.

  2) 主語+do動(dòng)詞的不同形式+….

  I play computer games everyday. →I don’t play computer games everyday.

  He plays computer games everyday. →He doesn’t play computer games everyday

  We played computer games yesterday.→ We didn’t play computer games everyday

  2肯定句變一般疑問句

  1)問:be動(dòng)詞+主語+…?

  答:Yes, 主語+be動(dòng)詞。/No, 主語+be動(dòng)詞+not.

  I am a teacher. →Are you a teacher?

  Yes, I am. No, I am not.

  He is a doctor.→ Is he a doctor?

  Yes, he is. No, he is not.

  They are students. →Are they students?

  Yes, they are. No, they are not.

  2) 問:助動(dòng)詞+主語+do動(dòng)詞的原形+…?

  答:Yes, 主語+助動(dòng)詞。/No, 主語+助動(dòng)詞+not.

  I play computer games everyday.

  →Do you play computer games everyday? Yes, I do. No, I don’t.

  He plays computer games everyday.

  →Does he play computer games everyday? Yes, he does. No, he doesn’t.

  We played computer games yesterday.

  →Did you play computer games yesterday? Yes, we did. No, we didn’t.
