初一英语上册句型转换方法

在以前的教学中经常碰到孩子学了几年英语，仍旧不会变换一些基本的英语句型转换，下面是小编收集整理的一些初一英语上册句型转换方法，大家一起来看看吧!

含有be动词的陈述句，通常把be提到句首，将第一人称变为第二人称，其余不变。

例：They are in the swimming pool.——Are they in the swimming pool?

I am making supper.——Are you making supper?

在陈述句中没有be，就要借助助动词do/does/did，将动词还原，第一人称变为第二人称，构成“Do/Does/Did+主语+动词原形+其他?”句型

例： I think maths difficult.——Do you think maths difficult?

Amy speaks English.——Does Amy speak English?

I paid two yuan for the pen.——Did you pay two yuan for the pen?

含有情态动词的陈述句，把情态动词提到句首，第一人称变为第二人称，其余不变。

例：He can drive a car.—— Can he drive a car?

含有have/has/had的陈述句，变疑问有两种形式：a.把have/has/had提到句首，第一人称变为第二人称，其余不变;b.加助动词do/does/did，第一人称变为第二人称，构成“Do/Does/Did+主语+have+其他?”句型。

例：Tom has a book.——Has Tom a book?

Tom has a book.——Does Tom have a book?

1，句子中有联系动词be或情态动词can ，may ，must或助动词will， have， had等词的，应在其后加not.

*句中有some , already的，将其变为any, yet

如：There are some people in the garden.

---There are not(或aren’t) any people in the garden.

We have already learned English for three years.

---We have not (或haven’t) learned English for three years yet.

*already变否定用yet，同时一般放句后。

注意have是助动词,还是实义动词。如果是实义动词，要用助动词do的否定式。

例：She has supper at six in the evening.

---She does not have supper at six in the evening.

2，句子中的谓语动词为实义动词时，则在动词前加don’t(doesn’t, didn’t), 原来的动词恢复原形(分词除外)。这类句子经常考的谓语动词是have和do 。

应掌握以下技巧：

如：She does (did) her homework everyday(yesterday).

----She doesn’t( didn’t) do her homework everyday (yesterday).

注意：在上句中，原谓语动词(即，实意动词does)前加否定助动词doesn’t, 原谓语动词does 变为原形 do

She has (had) a meeting today (yesterday).

----She doesn’t (didn’t) have a meeting today (yesterday).

注意：这里的has或 had 要变为原形have

3，had better句型是考试的重点内容之一。它常与主语缩写，如you’d ,这种缩写只要看后面有没有better, 即为had, 切忌误认为would

had better句型意思为“最好-----， 还是----好”，常有告诫、劝告、催促之意，其后接不带to 的不定式，即动词原形。它的否定形式， 一定要把not放在better后面。

*had better +动词原形------(肯定式)

had better not +动词原形-----(否定式)

如：You’d better catch a bus.你最好赶得上车子(赶快啊!)

You’d better not take these seats.你还是不要做这些位置(座位)

此句型的反义疑问句是：You’d better do it now, hadn’t you?

1，复合句改否定句应掌握think、believe和 feel这三个主句谓语动词后接宾语从句时整个句子的否定形式。这类句子改为否定句时，要对上述主句谓语动词进行否定，但否定意思转移到后面的宾语从句。

如：I think he will go there tomorrow.

--- I don’t think he will go there tomorrow.

汉语的意思是“我想他明天不会去那里”，千万不要译“我不想他明天去那里”。更不要把英语句子改成 I think he won’t(*严重错误) go there tomorrow.大错特错。

2，含有both词语的句子改否定句

陈述句含有both+名词或者both of +名词或代词宾格作主语时，改写否定句要用neither 替代both，注意把谓语动词复数形式改写为单数形式。

如：Both of them learn English in that school.

------ Neither of them learns English in that school.

句中含有 both A and B改否定句时，要将其改为 neither A nor B, 其谓语动词根据nor后面的名词的数做相应变化。

both A and B——变否定—— neither A nor B

如：Both Mary and Jim are students.

----- Neither Mary nor Jim is a student.

特殊疑问句由“疑问句 + 一般疑问句”构成，改写这种句子应把握两个关键，一是选准疑问词;二是将疑问词后的句子变成一般疑问句。注意以下技巧：

1. 对于时间划线用

what time ——(具体时间，如at 9:00)

how long ——(一段时间，如since 2000, for two days)

how often——( 频率时间，如once a year)

how soon——( 将来时间，如in a month)。

如：We have lived here since 1986.

-----How long have you lived here?

2, 对于职业划线用what.

如：Henry is an English teacher.

-----What is Henry?

3, 对距离划线用how far，对长度划线用how long，注意二者不能互换。

如：He travelled nearly ten thousand kilometers.

----How far did he travel ?

The Yellow River is 5464 kilometres long.

-----How long is the Yellow River?

4, 对数量划线用how many (后面跟可数名词复数)，how much(后面可跟不可数名词，也可单独作句子成份)

如：There are four persons in our office.

----How many persons are there in your office?

This book is six dollars.

-----How much is this book?
