一、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(méi)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。

　　二、肯定句改一般疑問(wèn)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(wèn)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(wèn)號(hào)。

　　3、 上述都沒(méi)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(wèn)號(hào)。

　　注意：句首的第一個(gè)字母要大寫(xiě)，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(wèn)，be提前，句末“?”別忘了。

　　4、 就一般疑問(wèn)句回答

　　一般疑問(wèn)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(yǔ)句順序?yàn)椋篩es + 主語(yǔ) + am /is/ are/was/were.|can.|do/does/did|; No + 主語(yǔ)+ 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.

　　三、對(duì)劃線部分提問(wèn)

　　“就劃線部分提問(wèn)”是小學(xué)階段英語(yǔ)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(yǔ)對(duì)劃線部分提問(wèn)之答題口訣 ：

　　一代：用正確的疑問(wèn)詞代替劃線部分。

　　二移：把疑問(wèn)詞移至句首

　　三倒：顛倒主謂語(yǔ)，但對(duì)主語(yǔ)或其定語(yǔ)提問(wèn)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(wèn)詞+一般疑問(wèn)句”(即： 先根據(jù)劃線部分找到特殊疑問(wèn)詞; 再把沒(méi)劃線的部分變成一般疑問(wèn)句的語(yǔ)序。)

　　★特殊疑問(wèn)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(wèn)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(wèn)詞用who

　　如:He is my brother. ---Who is he ?

　　3、劃線部分是“地點(diǎn)”，特殊疑問(wèn)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(wèn)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(wèn)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(wèn)詞用what

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

　　7、劃線部分是“顏色”，特殊疑問(wèn)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(wèn)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(qián)”，特殊疑問(wèn)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(wèn)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(wèn)“誰(shuí)”用who;

　　2.問(wèn)“誰(shuí)的”，用whose;

　　3.問(wèn)“地點(diǎn)哪里”，用where;

　　4.問(wèn)“原因”，用why;

　　5.問(wèn)“身體狀況”，用how;

　　6.問(wèn)“方式”，用how;

　　7.問(wèn)“年齡”，用how old;

　　8.問(wèn)“多少”，用how many;

　　9.問(wèn)"價(jià)錢(qián)”用how much;

　　10.問(wèn)“哪一個(gè)”，用which ;

　　11.問(wèn)“什么”，用what;

　　12.問(wèn)“職業(yè)”，用what;

　　13.問(wèn)“顏色”，用what colour;

　　14.問(wèn)“星期”，用what day;

　　15.問(wèn)什么學(xué)科，用what subject;

　　16.問(wèn)“什么時(shí)候”，用when;

　　17.問(wèn)幾點(diǎn)用What’s the time?或 What time is it?

　　四、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(yǔ)及句型表示出來(lái)。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(guò)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(jiǎn)單的公式來(lái)記憶。

　　1.肯定句變否定句

　　1) 主語(yǔ)+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(yǔ)+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(wèn)句

　　1)問(wèn)：be動(dòng)詞+主語(yǔ)+…?

　　答：Yes, 主語(yǔ)+be動(dòng)詞。/No, 主語(yǔ)+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(wèn)：助動(dòng)詞+主語(yǔ)+do動(dòng)詞的原形+…?

　　答：Yes, 主語(yǔ)+助動(dòng)詞。/No, 主語(yǔ)+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.
