英语中若干否定形式的比较
英语中若干否定形式的比较" 人们用语言表达思想时，总是要涉及到意义的正与反，肯定与否定两个方面。
每种语言都有它自己一套表达否定意义的形式和方法。
对中国学生来说，用not,never等词平铺直叙的否定，不难接受，也不易造成误解。
但是对暗含的否定，双重否定和重复否定等各种否定的变异形式就不那么习惯，常常是读之不解其意，用则容易失误。
为了要正确透彻地理解否定语句的内在含意，有必要了解英语否定意义的各种表达方式及其特点。
为此，本文就英语否定的几种表达方式彼此间的差别，以及某些混合交替，互相转化的现象进行对比和阐述。
一、一般否定与特指否定英语中根据否定对象和否定范围的不同，可以分为一般否定和特指否定。
这两类否定各自的特点是多方面的。
１．否定范围不同一般否定是英语中表达否定意义的最常用的方法，通常用否定词not来否定谓语动词，谓语被否定，全句的意义也就被否定。
例如：It was not (wasn't)so.Don't talk rot.特指否定是对谓语以外的成分加以否定，这种否定只涉及到句子的某个成分。
否定词not必须放在被否定的成分面前。
例如：I am ashamed of not knowing it.Not having heard from him,I wrote again.在否定句中，否定词的位置不同，被否定的成分也就不同，并且关系到该否定句是特指否定，还是一般否定。
比较下列句子：We told him not to go.（特指否定）We didn't tell him to go.（一般否定）not的位置不同可导致意义的差别。
当not用来否定谓语动词时，构成“一般否定”，即否定全句；当not用来否定后面不定式时，则构成“特指否定”，只起到局部否定的作用。
但是，在appear,expect,happen,inten d,plan,seem,tend,want,wish等动词后面跟不定式时，如果要构成否定语句，否定词not既可以置于这些动词之前，也可以置于后面不定式之前，意义完全相同。

C?”。
one of the +形容词最高级+名词复数”表示“最，，之一”特别提示more than 作为固定词组意为“多于”,常用于数词之前。
如果形容词前的 most 相当于very 时，不用定冠词the 。
9.1. 2. 江苏省句容市后白中学中考英语语法复习形容词、副词的比较等级牛津版【要点提示】英语里形容词和副词有三个比较等级，即原级、比较级和最高级，它们是用来表示事物的等级差别的。
构成：单音节词和部分双音节词一般在词尾加 -er 或-est ,多音节词和部分双音节词一般 在词前加more 或most 构成比较级和最高级，但形容词最高级前要加定冠词the,副词最高级前的the 可加可不加。
另外有些不规则的变化要记住。
如 good / well better f best , bad / ill —worse —worst, many / much more^ most, little —less least 等。
形容词、副词比较等级的基本用法：1. 原级常用于“ as +原级+ as ”结构，否定的原级用 not as ... as 或not so ... as 。
2. 比较级常用于“比较级 + than ”结构，否定比较级可用not as （so ）... as ... 结构，也可用less ... than ... 结构。
3. 最高级常用于“the +最高级+比较范围”结构，形容词的否定最高级也可用the least 。
形容词、副词比较等级的其它用法:1. 比较级前可用 much, a lot, a bit, a little, far, still, even等表示程度的词。
2. 比较级前可用“数词 +名词”构成的名词短语表示确定的度量。
3. 表示“越来越,, ，用“比较级+ and + 比较级”结构或“ more and more +原级”。
4. 表示“越,，，就越,，”，常用“ the+比较级，the+比较级”结构。
