英語中的句型轉換屬于較難的題型,對學生的英語綜合能力有一定要求。除了必須掌握基礎的詞匯外,還要對語法知識和句子語序有很好的掌握。
一、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
在can,should,will等后加not。
如:can not,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.
二、肯定句改一般疑問句的方法
1、把be動詞(am,is,are)放在句首,*個字母大寫,剩下的照抄,句末用問號。
(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,*個字母大寫,剩下的照抄,句末用問號。
(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*個字母要大寫,句尾標點應為"?"。
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?
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如:
—Are you an English teacher? → Yes,I am./ No, I am not.
—Is that a bird ? → Yes, it is. / No, it isn’t.
三、對劃線部分提問
"就劃線部分提問"是*階段英語學習的難點,但是一旦掌握了規律,就變得容易多了。*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。
★特殊疑問詞的確定要根據劃線內容而定,在*階段常出現的有以下幾種:
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?
Myfatheristhirty-three.---Howoldisyourfather?
6、劃線部分是"職業",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?
以下口訣要牢記:
1．問"誰"用who;
2．問"誰的",用whose;
3．問"地點哪里",用where;
4．問"原因",用why;
5．問"身體狀況",用how;
