画线提问一般是一个特殊疑问句 用特殊疑问词开头,结合生活实际,再会背单词就会了。
否定句一般是先看文中的单词 有行为动词（就是除了助动词和be动词外的单词）,就加do或does
肯定句就是对事物作出肯定判断的句子,否定句就是对事物作出否定判断的句子. 这两种句式在表达相同意思时,在语意上往往有轻重强弱的差别. 一般地说,同一句话,用否定句要比用肯定句语意要轻些,弱些.
例如：
1．这个道理容易明白.
2．这个道理不难明白.
这两句的意思差不多.
例1是肯定的说法,语气强些；例2是否定的说法,语气弱些.
否定句有两种类型：
一、一般否定句.
一般否定句只用一个否定词,常见的有“不”、“没”、“没有”等.
例如：
1．·激光不是一种普通的光.
2．··他没有来.
二、双重否定句.
双重否定句表示肯定的意思,它比肯定句语意要重些、强些.
例如：
···我不得不把这件事告诉了他.
例句用双重否定“不得不”表示没有任何理由隐瞒,比“我把这件事告诉了他”语意要强,语气也更加肯定.
下面看看肯定句与否定句的互换：
一、肯定句与一般否定句互换.
肯定句变换成一般否定句,只需用否定形式的同义短语去换原句的谓语中心词；否定句变换成肯定句,只需将原句中的否定形式短语用同义词换掉.

[思路分析]改否定句：方法一：找出句中的BE动词，在BE动词的后面加not(或缩写为isn’t, aren’t，但am not不能缩写)。如果句中有some,改为否定句时要变成any。方法二：找出句中的can，在can的后面加not(或缩写为can’t)。如果句中有some,改为否定句时要变成any。方法三：如果句中没有的BE动词和can,改否定句时要添加don’t或doesn’t。当句子的主语为第三人称单数时，就在主语后面加doesn’t，原句中的动词改为原形。除此之外都加don’t。如果句中有some,改为否定句时要变成any。[解题过程]（1）Green and jack don't read Lesson Five。（2）Those boys don't repeat Lesson Five。（3）Those girls don't open the door。（4）It is not time to begin the class。 否定句 开放分类： 英语、语法、名词、古代、汉语表示否定的句子。必须有否定词，古代汉语中否定词可以是副词“不”、“弗”、“毋”、“勿”、“未”、“否”、“非”，可以是动词如“无”，可以是代词如“莫”。 英语语法中否定句分为九种：1）一般否定句 I don't know this. No news is good news. There is no person (smoke)/not a person/not any person (smoke) in the house. 2)特指否定 He went to his office, not to see him. I am sorry for not coming on time. I don't think/believe/suppose/feel/imagine you are right. 3)部分否定 All the answers are not right All is not gold that glitters I don't know all of them. I can't see everybody/everything. Both of them are not right. 4)全体否定 None of my friends smoke. I can see nothing/nobody. Neither of them is right. Nothing can be so simple as this. 5) 延续否定 You didn't see him, neither/nor did I. You don't know, I don't know either. He doesn't know English, let alone/to say nothing of/not to speak of (更不用说） French. 6) 半否定句 We seldom/hardly/scarcely/barely hear such fine singing. I know little English. I saw few people. 7) 双重否定 You can't make something out of nothing. What's done cannot be undone. There is no sweet without sweat. No gain without pains. I can't help /keep/ laughing whenever I hear it. No man is so old but (that) he can learn. 8)排除否定 Everyone is ready except you. He did nothing but play. But for your help, I couldn't do it. 9)加强否定 I won't do it at all. I can't see it any more. He is no longer a boy.
