2013年小升初语法复习(八):肯定句、否定句

一、be动词:am, is, are

二、肯定句、否定句、一般疑问句和特殊疑问句定义

1.肯定句:表示肯定的意思, 即不含有否定词“不”。

比如:我是一个学生 I am a student.

他去上学 He goes to school.

2.否定句:表示否定的意思。

比如:我不是一个男孩。 I am not a boy

他不去上学 He does not go to school.

3. 一般疑问句:回答为“是yes”或者“否no”的问句。

比如:你是一个学生吗? Are you a student?

你喜欢英语吗? Do you like English?

4. 特殊疑问句:回答不是“是yes”或者“否no”的问句,根据提问内容具体回答。 比如:现在几点了? What’s the time?

哪一支笔是你的? Which is your pen?

三、肯定句、否定句、一般疑问句和特殊疑问句的相互转换

有am, is, are的句子,

am, is, are后面加上not,其余按顺序照抄。

肯定句变一般疑问句:把am, is, are提前放到句首并大写Am, Is, Are,其余照抄。 肯定句变特殊疑问句(就划线部分提问):分3步骤

第一步:先变一般疑问句

第二步:找合适的特殊疑问词代替划线部分

第三步:特殊疑问词提前放到句首,并大写,其余按顺序照抄,省略划线部分。

注意:1.一定先变一般疑问句。但是,如果问的是主语或主语的定语时,语序不变, 为"特殊疑问词(+主语)+陈述句"。

如:Li ming 's not here today. Who's not here today? 今天谁没来?

2.划线部分不能在特殊疑问句中出现。

例如:

肯定句、否定句和一般疑问句的互换

肯定句:This is a book.

否定句:This is not a book.

一般疑问句:Is this a book?

肯定回答:Yes, it is.

否定回答:No, it isn’t.

就划线部分提问(变特殊疑问句)

This is a book. 第一步:变一般疑问句 Is this a book?

第二步:找合适的特殊疑问词 Is this what ?

第三步:特殊疑问词提前放到句首,并大写,其余按顺序照抄,省略划线部分。What is this?

没有am, is, are的句子,

肯定句变否定句:在主语后面加上do not或者does not,其余按顺序照抄动词用原形 肯定句变一般疑问句:在句首加do或者does并大写,其余照抄。注意:动词用原形 3步骤

第一步:先变一般疑问句

第二步:找合适的特殊疑问词代替划线部分

第三步:特殊疑问词提前放到句首,并大写,其余按顺序照抄,省略划线部分。

注意:1.一定先变一般疑问句。但是,如果问的是主语或主语的定语时,语序不变,为 2

"特殊疑问词(+主语)+陈述句"。

2.划线部分不能在特殊疑问句中出现。

非单三时用do, 单三时用does

非单三 I like English.

Do you like English?

否定句:I do not like English.

单三 He likes English.

一般疑问句:Does he like English?

否定句:He does not like English.

就划线部分提问:I like English.

第一步:先变一般疑问句 Do you like English?

第二步:找合适的特殊疑问词代替划线部分Do you like what?

第三步:特殊疑问词提前放到句首,并大写,其余按顺序照抄,省略划线部分。 What do you like?

特殊:

1.some变为any。如:

There are some birds in the tree.→There aren't any birds in the tree.

但是,若在表示请邀请、请求的句子中,some可以不变。如: Would you like some orange juice?

与此相关的一些不定代词如something, somebody等也要进行相应变化。

2.and变为or。如:

I have a knife and a ruler.→I don't have a knife or a ruler.

3.a lot of (=lots of)变为many或much。如:

They have a lot of friends.(可数名词)→They don't have many friends. There is lots of orange in the bottle.(不可数名词)

→There isn't much orange in the bottle.

4.already变为yet。如:

I have been there already.→I haven't been there yet.
