形容词、副词的比较级和最高级
一、形容词、副词的比较级和最高级的构成规则
1.一般单音节词和少数以-er,—ow结尾的双音节词,比较级在后面加-er,最高级在后面加-est;
(1)单音节词
如:small→smaller→smallest short→shorter→shortest
tall→taller→tallest great→greater→greatest
(2)双音节词
如:clever→cleverer→cleverest narrow→narrower→narrowest
2.以不发音e结尾的单音节词,比较在原级后加—r,最高级在原级后加-st;
如:large→larger→largest nice→nicer→nicest able→abler→ablest
3.在重读闭音节(即:辅音+元音+辅音)中,先双写末尾的辅音字母,比较级加—er,最高级加-est;
如: big→bigger→biggest hot→hotter→hottest fat→fatter→fattest
4.以“辅音字母+y”结尾的双音节词,把y改为i,比较级加—er,最高级加-est;
如:easy→easier→easiest heavy→heavier→heaviest

5.其他双音节词和多音节词,比较级在前面加more,最高级在前面加most;

注意:形容词最高级前通常必须用定冠词 the,副词最高级前可不用。
例句: The Sahara is the biggest desert in the world。
6.有少数形容词、副词的比较级和最高级是不规则的,必须熟记。
如:good→better→best well→better→best
bad→worse→worst ill→worse→worst
old→older/elder→oldest/eldest
many/much→more→most
little→less→least
far →further/farther→ furthest/farthest
二、形容词、副词的比较级和最高级用法:
1。 原级的用法:用于两者之间对比,意思为“……和……相同”相当于the same as…
肯定句:A+动词.+as+形容词/副词原级+as B
Tom is as honest as Jack。 Jack runs as fast as Peter。
否定句:A+动词。+not as/so.+形容词/副词原级+as B
This tree is not as/so tall as that one.
2. 比较级的用法:
1)A+动词+形容词/副词比较级+than+ B
Susan is happier than Jane。 Lily run faster than Mary
注:形容词/副词比较级前还可以用much, even, still, a little,far, a lot, a bit来修饰.
2)数字(倍数)+形容词/副词比较级+than
I’m two years older than you。
Our classroom is twice bigger than yours.
3)比较级+and+比较级,表示“越来越……”
The earth is getting warmer and warmer。
4)the +比较级,the +比较级,表示“越……, 就越……”
The more, the better. 越多越好.(多多益善)
3. 最高级用法:
用于三者及以上的人或事物的比较,最高级前加the,最高级前有物主代词,序数词和名词所有格时,不加定冠词,后面跟带in或of表范围的短语。
1)one of the +最高级
Shanghai is one of the most beautiful cities in China.
2)比较级句型表达最高级意义
A+动词+比较级+than+any other+B(单数)
如:The Changjiang River is longer than any other river in China。
A+动词+比较级+than+the other+B(复数)
如:The Changjiang River is longer than the other rivers in China。
以上两句意思相当于:The Changjiang River is the longest river in China。

反意疑问句
1. 反意疑问句又叫附加疑问句,是指当提问的人对前面所儒术的事实不敢肯定,而需要向对方加以证实时所提出的问句。如:
You have been to Beijing, haven’t you? 你去过北京,不是吗?
2. 反意疑问句的两种基本句型
基本句型
例句
肯定陈述句 + 否定简略问句
Lucy is from England, isn’t she?
否定陈述句 + 肯定简略问句
Ann doesn’t like apples, does she?
注意:前一部分是一个陈述句,后一部分是一个简单的问句。完成后一部分简单问句时,要根据前面陈述句的动词时态和人称来选择适当的助动词进行提问,前后两部分的人称和动词时态要保持一致.
1. 反意疑问句用法说明
(1) 简单句式结构中反意疑问句的运用
① 当陈述句部分的主语是名词时,反意疑问句的主语必须用人称代词来代替.如:
Your brother has gone to the library, hasn’t he?
② 当陈述句的主语是指示代词this, that时,反意疑问句的主语用it代替;指示代词是these, those时,反意疑问句的主语用they代替。如:
That isn’t a useful book, is it?
These are important reading materials, aren’t they? 这些都是重要的阅读材料,不是吗?
④ 当陈述部分是everyone / everybody, someone / somebody, no one / nobody, none等表示人的不定代词时,反意疑问句部分的主语多用they (但有时也可用he);当陈述部分的主语是everything, anything, something, nothing等表示物的不定代词时,反意疑问句部分的主语用it。如:
Nobody came when I was out, did they? 我在外时,没人来过,是吗?
Everything has gone wrong, hasn’t it? 今天什么都出问题了,是不是?
⑤ 当陈述部分是“there be + 主语 + 其他”结构时,反意疑问句部分要用“be (not) + there”结构。如:
There are some bananas in the basket, aren’t there?
⑥ 当陈述部分有hardly (几乎不), seldom (很少), few (少,几乎无,修饰可数名词), little (很少,几乎无,修饰不可数名词), no, never (从不), nothing, nobody, nowhere等否定词或半否定词时,反意疑问句部分要用肯定形式.如:
He hardly remembers his old friend’s name, does he?
⑦ 如果陈述句部分有单词带否定前缀或后缀时,反意疑问句部分仍用否定结构。如:
It’s impossible for him to make such a mistake, isn’t it? 他不可能犯这样的错误,不是吗?
(2) 复合句结构中反意疑问句的运用
① 一般情况下,陈述句部分是主从复合句时,反意疑问句部分的代词和助动词应与主
句中的主语和谓语保持一致.如:
This is the second time that he has been to Japan, isn't it? 这是他第二次去日本,不是吗?
② 在宾语从句中,如果陈述句部分是“I think (believe, suppose, imagine, expect等) + 宾
语从句",反意疑问句部分应与宾语从句的主谓保持一致,并要注意否定转移。如:
I don't think you have heard of him before, have you? 我认为你以前没有听说过他,是吗?
注:当think等这些动词的主语不是第一人称,或主语是第一人称,而动词时态不是一般现时或一般过去时,这时,反意疑问句的助动词和人称代词要与主句保持一致。如:
Mary thinks you will come to the party, doesn’t she?
③ 当陈述句部分为主语从句时,反意疑问句的主语用it.如:
That she didn’t pass the entrance exam made his parents very angry, didn’t it? 他没有通过入学考试使得他的父母十分生气,不是吗?
(3) 祈使句结构中反意疑问句的运用
祈使句反意疑问句的构成,必须按其句子结构及讲话人的语气来决定其反意部分,有四
种形式.
① 祈使句的肯定形式,疑问部分用will you或won't you皆可。如:
Be sure to write to us, will you? 一定要给我们写信,好吗?
Come to have dinner with us this evening, won't you? 今晚跟我们一起来吃饭,好吗?
② 祈使的否定形式,其反意疑问句通常只用will you构成。如:
Don’t smoke in the meeting room, will you?
③ Let开关的祈使句,构成反意疑问句时,let’s用shall we构成反意疑问句,其他均用will you.如:
Let’s take a walk after supper, shall we? 晚饭后,我们去散步,好吗? (表建议)
Let the boy go first, will you? 让那男孩先走,好吗?
Let us know your address, will you? 请把你的地址告诉我们,好吗? (表请求)
④ 当陈述部分含有used to (过去常常)时,附加问句部分的谓语可用use(d)n’t或didn’t。
