七年級英語怎樣句型轉(zhuǎn)換
在七年級的英語中,句型轉(zhuǎn)換也是一個重要知識,那么七年級英語怎樣句型轉(zhuǎn)換呢?下面是學(xué)習(xí)啦小編為你整理的七年級英語句型轉(zhuǎn)換的方法,希望大家喜歡!
七年級英語句型轉(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)們對相關(guān)知識要熟練掌握。
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,其后的動詞也變了,一個網(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動詞(常見的有am,is,are)。這種情況只需把be動詞提到句首,將句號變?yōu)閱柼柤纯?。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將其變?yōu)榈诙朔Q,同時其所對應(yīng)的be動詞也要跟著改變。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,用do。
(3)另外還可以根據(jù)陳述句中的動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互逆的過程。改寫為否定句,要看句子中是否有be動詞。有be動詞的,在be動詞后加not;沒有be動詞的,在動詞前加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,如果動詞前用了doesn’t,那么這個動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.。
改為肯定句的時候,要注意把doesn’t去掉之后動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.。
對劃線部分進(jìn)行提問
對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劃線部分提問其實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(對事物提問)、why(對原因提問)、who(對人提問)、when(對時間提問)、how(對狀況和方式提問)、how old(對年齡提問)、how much(對價格提問)、where(對地點提問)。準(zhǔn)確把握劃線部分所對應(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
合并句子的實質(zhì)就是概括句子。例如:This is my father. This is my mother. 在這兩個句子中,這個加這個就是這些,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.

肯定句改否定句的方法 :
1、 在be動詞后加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,在動詞前加助動詞否定形式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動詞放在句首,剩下的照抄,(some 改成any,I改成you,my改成your,)句點改成問號。
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,)句點改成問號。
3、 上述都沒有的,在句首請助動詞Do/Does/Did幫忙,剩下的照抄,(some 改成any,I改成you,my改成your,)句點改成問號。
注意:句首的第一個字母要大寫,句尾標(biāo)點應(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。 語句順序為:Yes + 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,但是一旦掌握了規(guī)律,就變得容易多了。 小學(xué)英語對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,但對主語或其定語提問時除外(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”,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動詞+主語+…?
答:Yes, 主語+be動詞。/No, 主語+be動詞+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:助動詞+主語+do動詞的原形+…?
答:Yes, 主語+助動詞。/No, 主語+助動詞+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.
