一、much修饰比较级
修饰比较是副词much的常见用法,“much + 比较级”的意思是“更……”“……得多”。如:
It’s much colder today than it was yesterday. 今天比昨天冷得多。
It was much worse than I thought. 它比我想像的还要糟得多。
We will be a much better football team next year. 明年我们将会成为一支更好的足球队。
二、much修饰最高级
much修饰最高级应置于最高级前的定冠词之前,而不是之后。“much + the + 最高级”的意
思是“最最……”“绝对是最……”。如:
This is much the most difficult. 这是最最难的。
That’s much the best plan. 那绝对是最好的计划。
Of the three boys Nick is much the cleverest. 这三个男孩中,尼克最最聪明。
英语
三、much修饰形容词的原级
much修饰形容词原级的情形主要见于那些由过去分词转化来的形容词。如:
I was much annoyed. 我很不高兴。
She wasn’t much surprised. 她并不太惊讶。
注:有个别非分词转化来的形容词有时也可用much修饰,但这种用法很有限,通常只见于
good, different等少数几个形容词。如:
I don’t think this battery is much good. 我并不认为这种电池非常好。
The new school isn’t much different from the old one. 新学校与老学校区别不太大。
四、much修饰副词too
much too 为习语,其中的much修饰副词too;much too可视为too的加强说法,其语气
比单独用too更强。如:
He spoke much too fast. 他说话说得太快了。
This is much too heavy for you to lift. 这东西太重,你拿不起来。
注意:much too与too much词序不同,用法也不同。从句法功能上看,much too的用法
与too相同,但比too的语气更强;而too much在用法上则与much相同,但比much 语
气更强。比较:
He drives much too fast. 他开车开得太快了。
The shoes are much too small for me. 这鞋子我穿太小了。
There is too much rain. 雨水太多了。
You have given me too much. 你已经给我太多了。
五、much修饰介词短语
英语
much主要用于修饰由like, in, to等少数介词所构成的介词短语。如:
The baby doesn’t look much like you. 这婴儿长得不大像你。
They’re very much in love with each other. 他们彼此在热恋中。
Much to my surprise, she did it by herself. 让我极为惊讶的是,这竟然是她自己做的。
六、much修饰动词
much修饰动词时,通常只用于否定句或疑问句中,一般不能用于肯定句中(除非前面有 very,
too, so 等之类的修饰语)。如:
正:She doesn’t like him much. (用于否定句,故正确)
正:She doesn’t much like him. (用于否定句,故正确)
正:Does she like him much? (用于疑问句,故正确)
正:Does she much like him? (用于疑问句,故正确)
正:She likes him very [too, so] much. (其前有修饰语,故正确)
注意以下误句:
误:She likes him much. / She much likes him. (因为它用于肯定句,且其前没有修饰语,
故不正确)
但是,不带修饰语的much有时也能在肯定句中修饰动词,但这通常只限于admire, affect,
appreciate, dislike, enjoy, look forward to, prefer, regret等少数动词,且much通常只能放
在句中,不放在句末。如:
We much appreciate your invitation. 我们非常感激你的邀请。
We would much prefer to be given money. 我们还是更喜欢有人给我们钱。
英语
These factors have much affected the building of nuclear plants. 这些因素极大地影响了
核电站的建立。
七、much修饰as
much as 可视为习语,其意为“虽然”,用法与though相似。如:
Much as I’d like to help, there isn’t a lot I can do. 尽管我愿意帮忙,却没有很多事我能做。
Much as he admired her looks and her manners,he had no wish to marry her. 虽说他很
欣赏她的外貌和仪态,他却无心和她结婚。
八、much修饰the same
much 修饰the same,从表面上是加强了the same的语气,但实际上是缓和了其语气,其
意为“情况大致相同”“几乎差不多”“没什么变化”。如:
The patient is much the same this morning. 今天早上病人情况几乎没什么变化。
Whichever method you use, the result is much the same. 不论你用哪一种方法,结果都差
不多。
They eat much the same thing for breakfast every day. 他们每天吃的早餐几乎都一样。
1,大家知道,a little 用于修饰比较级的用法比较广泛。如:
The paper should be a little thicker. 这纸应该再厚一点儿。
Can’t you walk a little faster? 你不能走得快一点儿吗?
Do work a little harder. 务必请你工作再努力一点吧。
Couldn’t you come a little earlier? 你是否能提前一些日子来?
I wish you would stay a little longer. 我希望你再待一会儿。
Do the vegetables a little longer. 让蔬菜煮的时间长一点。
英语

A little more slowly. 再慢一点(from )。
You might tune that wireless a little lower, children. 你们还是把那收音机开小一点儿吧,孩子
们。
2,但是,副词little修饰比较级时,其用法比较有限,主要用于修饰better和more:
1. little better:其意为“好不了多少”,相当于not much better。如:
His second suggestion was little better than his first. 他的第二条建议比第一条好不了多少。
His legs were in little better shape than they had been the year before. 他的双腿与前一年相比没
有多少好转。
2. little more (than):其意为“只”“只不过”。如:
He was little more than a child when his father died. 他父亲去世时,他差不多还是个孩子。
Aid to the Third World is at present little more than a drop in the ocean. 目前对第三世界的援助
不过是杯水车薪。
He left school with little more than a basic education. 他只接受了点基础教育就退学了。

5. 形容词最高级用法
the + 最高级 + 比较范围
1)形容词最高级前通常必须用定冠词 the,例如:
The Sahara is the biggest desert in the world. 撒哈拉沙漠是世界上最大的沙漠。
形容词most前面没有the,不表示最高级的含义,只表示"非常"。例如:

=Nothing is easier than this。
=This is the easiest thing。
much和more的用法
much是用来修饰比较级的,much more beautiful
more是用来构成比较级的,more beautiful
有much more than这种用法吗?
不是more than而是much more than
在英语中,这种用法是有的,因为much后边要加形容词的比较级,more than是比较级句式,
所以就能加哦!还有,如果more后边有像beautiful,careful一类很长的词,这个用法也对!
加油!
many , most ,much , more的意思和用法
many+可数复数名词,表“很多……”
most+形容词,表“最……”
much+不可数名词,表“很多……”
more+形容词,名词,表“更,更多……”
more 和 much 的区别和关于这两个词的用法,详细解释,不要太长,要精华就可以,最好
有举例
A more 是much和many的比较级既可以修饰可数名词也可以修饰不可数名词
而much仅仅是修饰不可数名词表示很多,也可以做程度讲解.其实这两个词很简单的
英语
B much和very连用至于句尾当副词用而more不可
C 在more做比较级修饰形容词的时候 much可以用来修饰more 例如
英语中more,much和much more的区别与用法
more是指较多,用于比较级
much是指很多,用于不可数名词
much more是指较多(更进一步),也用于比较级
more--可数不可数都行
much--只修饰不可数或比较级
much more--只修饰形容词或副词,不能修饰名词
关于many more 和 much more
用much修饰more只是一种用法。如果不是一定把它们都当成固定词组,而可以是单词的
组合的话,它们的用法有区别。
many more本身不是一个整体。比如“many more people”就是很多其他的人、更多的人这种
意思。它的后面加上可数名词复数,实际上是这样一种用法:more可以置于数词或者any,
some,no,a few,a little,many,much的后面,表示另外的、附加的、超过的。
much more的意思比较丰富,它后面加的是不可数名词。除了与many more一样也有上述用
法外,它还可以作为比较级。这时,more就是一个简单的比较级的形容词,而much是修饰
比较级的副词,相同用法还有much bigger,much hotter等,语法结构相同。和much一样具
有修饰比较级作用的还有rather,even,a little等等。
同时,more不仅可以单独作为比较级,而且还可以和形容词一起构成比较级,这时的much
就是修饰整个比较级而不是单纯修饰much的了。如much more beautiful。但是不用把它想
的太复杂,它和more直接作比较级时语法相同,只不过much后面的比较级长了一点而已
例1。 Larry, I can't give you an answer ____ I think it over," said joe.
before ?
until?
until如果用在肯定句中,则主句的动词必须是延续性动词。until是终点,指这个动作或状态一直延续到until
的时间为止。
I waited until he came back 我一直等到他回来。
until 用在否定句中,主句动词是非延续性动词(换句话说,如果主句动词是非延续的就要用否定),until
英语
是起点,指这个动作在until的时间才开始
I didn't leave until he came back 直到他回来我才走
楼上I can only give you an answer until I think it over. 这个句子是错误的。
在这道题里其实并不强调“我不给你答案”这个状态的延续,而是强调在考虑之前“不能”给你答案,所以该
用before,说明先想想再告诉你
例2。 I could not finish the homework________.
A.until he has come B.before he came
C.when he comes D.by he had come
until he has come 强调直到....才, 是一种临界状态
直到他回来我才完成作业
before he came 强调再他回来之前 我没法完成作业
例3。 But it may still be many years ( )this problem could finally be solved.
这道题选before。给的简析是“到这个问题最终解决仍然还要许多年”,
例4。 ___can i go out paly with.....,mum?
__No, you can't ____your home work is being done.
before ?
until?
ago是指从这时算的,before指从过去的某一时刻向前推
after是指在......之后until与TILL差不多until和till两者都可作介词、连词,一般情况下可以互换使用。用
于肯定句时,主句的动词只用延续性的,它所表示的动作一直延续到till或until表示的时间为止,意为“直
到……为止”;用于否定句时,主句的动词一般是非延续性的,也可以是延续性的,它所表示的动作直到till
或until所表示的时间才发生,意为“直到……(才)”。如:
She watched TV until / till her mother came back.
她看电视直到她母亲回来。(看电视的动作延续到母亲回来才结束)
She didn”t watch TV until / till her mother came back.
直到她母亲回来她才(开始)看电视。(看电视的动作直到她母亲回来才发生)实际上,只要我们把握
住两者使用时本身的含义及主句动词是终止性的,还是延续性的,肯定式,还是否定式两大
点,就能容易地解决这类问题。现详细阐明如下:
一、在下列情况下,两者可互换用,但含义略有不同。before表示“在……之前”的意思,强
调时间先后关系;而until表示“直到……才”的意思,主句是肯定句则表示主句动作的终止
时间;主句是否定句则强调主句动作的起始时间。
1.主句为否定式终止性谓语动词。常见的动词是open,start,leave,arrive,finish,
stop等。例如:
(1)The noise of the street didn't stop until/before it was midnight.
(2)The children won't come back until/before it is dark.
(3)I didn't leave the lovely boy until/before his mother came home.
2.主句为肯定式、延续性谓语词,这类动词用stand,stay,talk,be,wait等。例如:
(1)He lived with his parents until/before he graduated from school.
(2)I will wait until/before he comes to my help.
(3)I shall stay heer until/before you come back.
二、在下列情况下,用before不用until。
1.主句这肯定式、终止性谓语动词,只用before。例:
英语
(1)He fell asleep before I could take off his clothes.
(2)We arrived there before it atarted to rain.
(3)The holiday came to the end befor I knew it.
(4)He almost knocked me down before he saw me.
2.主句谓语动词强调动词的迟缓性,只用before,常伴有时间段状语或时间段暗示。例:
(1)It was quite some time before he found the elephant at all.
(2)We had walked a long way before we found some water.
(3)We had sailed for two days before we saw the land.
(4)The fire lasted about four hours before the firefighters could
countrol it.
(5)It was midnight before my brother came home.
(6)It was three months before they met 3.如果强调从句谓语动作未发生,就发生主句谓语动作,只用before。常译为“未及”,
“不”或“不等 就”。例:
(1)We can leave early in the morning before it gets too hot.
(2)I must write it down before I forget it.
(3)We do want to buy something now before prices go up.
4.表“与其说 倒不如”,“与其 毋宁 ”只用before。例:
(1)I would give up my job before I'd agree to be dismissed.
(2)He will die of hunger before he will steal.
5.在某些特定句型中用before。例如:
(1)It was not long before the whole country rose up.
(2)It will probably not be long before they understand each other.
三、下列情况一般区别用until。
1.主句是持续性谓语动词时,肯定、否定都可以,但意义完全不同。肯定表动作终止,而否
定表动作开始。例如:
(1)We discussed the problem until/before he came back.我们一直讨论到他回来。
(2)We didn't discuss the problem until he came back.我们一直等到他回来后才讨论问
题。
2.not until句型尽管在某些情况下可与before互换用,但在强调句中一般仍用until。
例如:
例如:
(1)It was not until he told me that I knew it.
(2)It was not until he finished his homework that he went home.
before 的用法归纳
before 可以和过去完成时连接。
一。 过去完成时主要有以下几点用法:
1. 表示过去某一时间或动作之前已经发生或完成的动作或存在的状态。句中常用by,
before, when, until等词引导的时间状语。它是以过去某一时间为起点,所以过去完成时
是一个相对的时态,表示的是“过去的过去”。只有和过去某时间或某动作相比较时才能用到
它。例如:
Most of the guests had left when he arrived at the party. 当他到达晚会时,他发现大多数客人已
经离开了。
英语
2.过去完成时还可表示过去某一时刻之前发生的动作或状态持续到过去某个时间或持续下
去,常与for, since等词连用。例如:
When Jack arrived, he learned Mary had been away for almost an hour. 当杰克到时,他得知玛丽
已经离开快一个小时了。
3. 用于并列句:一个并列句用的是过去式,如果另一个并列句表示的动作早于过去式这一
动作,这时需用过去完成时。例如:
Tom flew home, but his father had already died.汤姆乘飞机回家,他的父亲却已经去世了。
4. 某些动词的过去完成时表示过去未实现的希望、计划或打算。常用的动词有hope, expect,
suppose, think, want, wish等。例如:
They had hoped to be able to arrive before ten. 他们本来打算能在10点之前到达。
5. 在before, after, as soon as等引导的从句中,由于这些连词本身已经表示出时间先后,
所以可以用过去时来代替过去完成时。例如:
二。 一般过去时和过去完成时用法有哪些不同?
1. 在主从复合句中的用法不同
(1) 用在宾语从句中
在主句谓语为一般过去时的宾语从句中,既可用一般过去时,也可用过去完成时。但两种时
态的意义明显不同。试比较下列两组句子:
She said she was a doctor. 她说她是位医生。(说话时仍为医生)
She said she had been a doctor.她说她曾当过医生。(说话时已不是)
She said she had been a doctor for twenty years.她说她当过20年的医生。(主要强调
说话时已当过20年医生,此状态可能已经结束,也可能还没有)
但是,如果从句中有表示具体时间的状语,则常用一般过去时。例如:
He said he was born in 1986. 他说他是 1986年出生的。
(2) 用在含有after的主从复合句中
在含有after的主从复合句中,一般在从句中使用过去完成时,主句中使用一般过去时。例
如:
After he had done his homework, he went out to play football.
因连词after本身能明确表示时间的先后关系,因而多数的主句和从句均使用一般过去时。
例如:
After he arrived in England, Marx worked hard to improve his English.
(3) 用在含有before的主从复合句中
用在含有before的主从复合句中,一般在从句中使用一般过去时,主句中使用过去完成时。
例如:
Lily had written some letters before she went out shopping.
有时,也可以在从句中用过去完成时,主句中用一般过去时,这样就可使描述更为生动。试
比较:
We got to the station before the train had left. 火车尚未开动之前,我们就到了车
站。
We had got to the station before the train left. 火车开出之前,我们就已经到了车
站。
英语
像after一样, before本身就能明确地表示时间的先后关系,故多数主从句均使用一般过
去时,而无需使用过去完成时。例如:
Many people left for home before the film ended.电影尚未放完,许多人就起身回家了。
(4) 用在含有when的主从复合句中
由于when本身不能明确表示时间的先后关系,故先发生的动作应用过去完成时,后发生的
动作只需用一般过去时。这样用过去完成时的可能是主句,也可能是从句。例如:
When all his money had been used up, Peter had to turn to a friend for help. 当
他的钱全都用光时,彼得只好转而求助于一个朋友。
有时,主句和从句的谓语动词的先后关系十分明确,两个动作紧接着 发生,前一动作导致
后一动作,这时两者均用一般过去时即可。例如:
When the meeting was over, we left the hall. 散会后,我们就离开了大厅。
2. 叙述几个连续的动作用法不同
在叙述两个或两个以上接连发生的动作用and, but, so或then等连接并按时间发生的先
后顺序叙述时,只需用一般过去时。例如:
She entered the room, turned on the light and found everything stolen.
I lost my pen but soon found it.
She lost her pen, so I lent her mine.
但是,如果两个先后发生的动作不是按时间的顺序排列或叙述时,为明确动作发生的先后顺
序,先发生的动作就得用过去完成时。例如:
The farmers were in high spirits because they had got another good harvest. 农民
们兴高采烈,因为他们又获得了一次好收成。
3. 表示与过去还是现在相反的情况不同
一些表示心理活动的动词,如think, know, expect, mean, hope, want, suppose
等,用一般过去时可表示存在于过去而非现在的心理活动或事与愿违的情况。例如:
I didn't know you were here. 我不知道你在这儿。
而这些词的过去完成时则表示的是过去未曾实现的愿望、打算、想法或意图等。例如:
We had hoped that you would be able to visit us. 我们原本希望你去看我们。
be important to sb 某事对某人重要
Exercise is important to us.
be important for sb 对我们来说......是重要的
It's important for us to learn English well.
英语
这两者没有冲突,看楼主适用的具体语境:
1.be important to sb./sth.对……是重要的
2.be important for sb to do sth.做某事对某人重要
be important to sb.: ……对sb.而言是很重要的,强调对某人很重要的东西。。
eg.
What is important to you is also important to me.
对你重要的事对我也重要。
Money is important to me.
be important for sb.(to do sth.):某人……是很重要的,强调做某事对某人的重要性。
eg.
It is important for you to get there early.
一、 写出下列形容词的比较级。
1. quiet _______ 2. interesting _________ 3. outgoing _________
英语
4. many _______ 5. ill ______ 6. wet ___________
7. good ________ 8. athletic ______ 9. funny _________ 10.
important __________
二、 Ask and answer in pairs to compare things.
Step 3: Let’s learn and practice the grammar. (语法讲解与操练。)
上节课,我们学习了形容词比较级的基本用法,即用于两个人或事物的比较,其结构形式如
下:
主语+谓语(系动词)+ 形容词比较级+than+ 对比成分。也就是, 含有形容词比较级的主句
+than+从句。注意从句常常省去意义上和主句相同的部分, 而只剩下对比的成分。
It is warmer today than it was yesterday.
今天的天气比昨天暖和。
This picture is more beautiful than that one.
这张照片比那张照片漂亮。
The sun is much bigger than the moon.
太阳比月亮大得多。
Today we’re going to learn some new ways of comparing things.(今天我们来学习进行比较的几
种其他用法。)
1. 同级比较
两个比较对象程度相同时,用“as+形容词原级+as的结构”
例如: Tom is as tall as his brother.
My hair is as long as mine.
在这两种结构中,第一个as是副词,而第二个as是连词;在第二个as的后面接名词、句子
或代词的主格(一般不要接代词的宾格)。例如:
His bedroom is not as big as his sister's.
It is not so hot as yesterday.
[学生两人一组使用as… as… 及 not as(so) … as…练习同级比较。]
2、在比较级 + than的结构前可以加上某些副词类的词,以对其进行修饰,如:far(远),
even(甚至),much(许多),still(更,还),a lot(许多),a little / bit(一点),rather(相
当地),等等。例如:
She’s a little more outgoing than me.
My bike is much newer than his.
3、 比较级中的两个特殊作用的结构是:
a. The + 比较级 + 句子,the + 比较级 + 句子 。它表示的意义是"越(怎么样就)越
(怎么样)",在这个结构中的两个"比较级"不要求一定词性相同,它们各自的词性要依句
子的需要而定。例如: The
harder you work at your study, the better grades you will have. 你学习越努力,你的成绩就越
好。
The more we get together, the happier we’ll be.
英语
朋友越多, 我们就越高兴。
[Ask and answer in groups to make some new sentences.]
b. 比较级+ and + 比较级。它表示的意义是"越来越(怎么样)",在这个结构中的
两个 "比较级"则要求词性相同。例如:
Our country becomes more and more beautiful.
When spring comes, the weather is warmer and warmer.
4、 比较对象中一方不及另一方时,用“not as(so)+形容词原级+as ”或“less+形容词原级+
than”的结构。 He is not as careful as his sister. == He is less careful than his sister.
== His sister is more careful than he.
[Ask and answer in groups to make some new sentences.]
5、 在两者之中选择“较为、、、 ” 的一个, 比较级之前加the.例如:
6、比较级的形式表达最高级的意思。有的人或事相比较。做这种句子时有一点要特别注意--别忘了常在比较状语中用any other ,
else类的字眼,以将比较主体排除在比较对象以外,因为自己不可以与自己相比较。例如:
He is taller than anyone else in our class.
He is taller than the other students in our class.
He is taller than any other student in our class.
He is the tallest in our class.
[以上四句话意思相同]
[出示习题,老师引导学生在理解的基础上做同义句转换。]
Step 4: Take notes about these grammar points.
Step 5: Practice (课堂练习):
a. Choose:
1. Today he is _____ than yesterday.
A. very better B. a little better C. well D. best
2. The white horse is so ____.
A. strong B. stronger C. a little stronger D. strongest
3. Cathy did quite ____ in the English test, I did even ____.
A. better; well B. well; well C. well; better D. better; better
4. Of the two Australian students, Masha is ___ one. I think you can find her
easily.
