高中英语数词用法小结篇2

数词在高考试卷文言文阅读题中出现的频率比较高, 而高中文言文中一些数词的用法与现代汉语数词的用法有所不同, 因此有必要梳理一下高中语文教材 (人教版必修一至必修五, 人教版选修《中国古代诗歌散文欣赏》《中国文化经典研读》, 下同) 中的文言文数词用法。

高中语文教材文言文中数词共出现大约650次, 它们的用法大致分为如下几类:

一.表示确数

有四种形式:

1、少数文言文数词后有量词。

(1) 一种相思, 两处闲愁。 (《一剪梅》)

(2) 山一程, 水一程……风一更, 雪一更。 (《长相思》)

(3) 会须一饮三百杯。 (《将进酒》)

(4) 如一条大路, 又有一条小路。 (《<朱子语类>三则》)

2、大多数文言文数词后无量词, 数词直接用在名词或动词前面, 直接修饰限制中心语。

(1) 蟹六跪而二螯…… (《劝学》)

(2) 以奉我一人之淫乐。 (《原君》)

(3) 一寒士乡试中式。 (《陶庵梦忆序》)

(4) 轩凡四遭火, 得不焚, 殆有神护者。 (《项脊轩志》)

例 (1) (2) (3) (4) 中数词后就分别省去“只”、“对”、“个”、“次”等量词。

3、将作定语或状语的数词置于被修饰限制的中心语之后。

(1) 吾年十九, 始来京城。 (《祭十二郎文》)

(2) 狱旧有室五, 名曰现监。 (《狱中杂记》)

(3) 铸以为金人十二, 以弱天下之民。 (《过秦论》)

(4) 举所佩玉决以示之者三。 (《鸿门宴》)

例 (1) (2) (3) 中数词“十九”“五”“十二”就是定语后置, 例 (4) 中数词“三”就是状语后置。

4、将作补语的数词置于中心词之前。例如:

(1) 室西连于中闺, 先妣尝一至。 (《项脊轩志》)

(2) 回眸一笑百媚生, 六宫粉黛无颜色。 (《长恨歌》)

例 (1) (2) 中的数词“一”就是补语前置。

二.表示约数

约数是表示与实际数接近的数目。文言文中表示约数的方法有下列几种:

1、用两个邻近的数表示。如:

(1) 未至二三里, 摧藏马悲哀。 (《孔雀东南飞》)

(2) 积五六年。 (《苏武传》)

(3) 用其二三十万为河伯娶妇。 (《西门豹治邺》)

(4) 右胁大铁锤, 重四五十斤。 (《大铁锤传》)

(5) 冠者五六人, 童子六七人。 (《子路、曾皙、冉有、公西华侍坐》)

例 (1) (2) (3) (4) (5) 中的“二三”“五六”“二三十”“四五十”“五六”“六七”表约数。

2、在基数词前加“数”、“且”、“将”、“约”、“盖”等表示。如:

(1) 杀数十百人。 (《项羽之死》)

(2) 将数百之众, 转而攻秦。 (《过秦论》)

(3) 其广数千里。 (《逍遥游》)

(4) 北山愚公者, 年且九十。 (初中《愚公移山》)

(5) 舟首尾长约八分有奇, 高可二黍许。 (初中《核舟记》)

例 (1) (2) (3) (4) (5) 中的“数”“且”“奇”表约数。

3、在基数词后加“许”、“余”、“所”等表示。如

(1) 还家十余日, 县令遣媒来。 (《孔雀东南飞》)

(2) 方宅十余亩, 草屋八九间。 (《归园田居》)

(3) 人马仆地, 杀三十许人。 (《大铁锤传》)

(4) 步行负弓矢从百许人。 (《大铁锤传》)

(5) 寺在蕲水郭门外三十里许。 (《游沙湖》)

例 (1) (2) (3) (4) (5) 中的“余”“许”表约数。

三.表示虚数

虚数, 不是实际数目。数词“三”“九”“百”“千”“万”常常被用来表示虚数, 泛指“多”。

这是因为古人释“三”为“天地人之道也”, 含有广大众多之义;又认为“九”是“数之终, 物之广, 阳之极”, 故用以称“多”。例如:

(1) 自我徂尔, 三岁食贫。 (《氓》)

(2) 三岁为妇, 靡室劳矣。 (《氓》)

(3) 亦余心之所善兮, 虽九死其未悔。 (《离骚》)

(4) 三人行, 则必有我师焉。 (《师说》)

(5) 闻道汉家天子使, 九华帐里梦魂惊。 (《长恨歌》)

(6) 滟滟随波千万里, 何处春江无月明。 (《春江花月夜》)

(7) 千骑拥高牙。 (《望海潮》)

例 (1) (2) 中“三岁”表示多年, 例 (3) 中的“九”表示多次, 例 (4) (5) (6) (7) 中的“三”“九”“千”都表示多。

四.表示加数

一般在整数与零数之间加一“有 (通‘又’) ”字, 表示两数相加。例如:

(1) 旬有五日而后反。 (《逍遥游》)

(2) 吾十有五而志于学。 (《<论语>十则》)

(3) 臣密今年四十有四, 祖母今年九十有六。 (《陈情表》)

(4) 邹忌修八尺有余。 (《邹忌讽齐王纳谏》)

例 (1) (2) 中“旬有五”“十有五”为十五, 例 (3) 中“四十有四”“九十有六”为四十四、九十六, 例 (4) 中“八尺有余”为八尺多。

五.表示分数

其形式有三:一是分母与分子连用, 省略现代汉语的“分之”二字;二是分母与分子之间加入一个动词;三是分母与分子之间加入名词 (也可省略) 和“之”字。例如:

(1) 盖余所至, 比好游者尚不能十一。 (《游褒禅山记》)

(2) 煤炭居十七, 木炭居十三。 (《治铁》)

(3) 勾者十四三, 留者十六七。 (《狱中杂记》)

(4) 染此者十不一二。 (《狱中杂记》)

例 (1) (2) (3) 都属于第一类, “十一”为十分之一, “十七”为十分之七, “十三”为十分之三, “十四三”为十分之四三, “十六七”十分之六七;例 (4) 都属于第二类, 分母分子间分别加入“不”“十不一二”意思是十个里没有一二个。

六.表示倍数

与现代汉语的倍数表示法差不多, 一般在基数词后加“倍”字。若是一倍, 只用一个“倍”字表示;若是几个倍数连用, 一般只留一个“倍”字, 其余直接用数词表示。例如:

(1) 尝以十倍之地, 百万之众, 叩关而攻秦。 (《过秦论》)

(2) 与战胜而得者, 其实百倍———与战败而王者, 其实亦百倍。 (《六国论》)

(3) 夫以千万倍之勤劳, 而几又不享其利。 (《原君》)

(4) 一人倍之, 伤肤, 兼旬愈。 (《狱中杂记》)

(5) 此其人之勤劳, 必千万于天下之人。 (《原君》)

例 (1) (2) (3) 在“十”“百”“千万”后加“倍”字, 例 (4) 表示加倍, 例 (5) “千万”表示千万倍。

七.表示乘数

用相连的两个数相乘, 表示一个数目, 此种用法较少。例如:

(1) 三五之夜, 明月半墙…… (《项脊轩志》)

(2) 正见当垆女, 红装二八年。 (初中《江夏行》)

(3) 六六雁行连八九, 只待金鸡消息。 (初中《水浒》)

例 (1) 中的“三五”都指旧历的每月十五日;例 (2) 中的“二八”指十六岁;例 (3) 中的“六六”“八九”分别指三十六和七十二, 两数相“连” (加在一起) 就是一百零八。

八.数词活用

1、活用为名词。一般位于主语或宾语的位置。例如:

(1) 若但尝一。 (《<百喻经>六则》)

(2) 合从缔交, 相与为一。 (《过秦论》)

(3) 一在天之涯, 一在地之角。 (《祭十二郎文》)

例 (1) 中“一”意思是一个庵婆罗果子, 具有名词性, 作宾语;例 (2) 中的“一”是一个整体, 例具有名词性, 作宾语; (3) 中的“一”意思是一个、一个人, 也具有名词性, 作主语。

2、活用为动词。可以用来作句子的谓语。例如:

(1) 六王毕, 四海一。 (《阿房宫赋》)

(2) 固知一生死为虚诞, 齐彭殇为妄作。 (《兰亭集序》)

(3) 内外不一, 心手不相应。 (《文与可画筼筜谷偃竹记》)

(4) 人一能之, 己百之;人十能之, 己千之。 (《<中庸>节选》)

(5) 女也不爽, 士贰其行。士也罔极, 二三其德。 (《氓》)

例 (1) (3) 中的“一”意思是统一, 具有动词性, 作谓语; (2) 中的“一”意思是看作一样; (4) 中的“百”“千”就是一百次地做、一千次地做; (5) 中的“贰”“二三”分别是有二心、有时二有时三的意思。

3、活用为形容词。一般用作句子的谓语。例如:

(1) 蚓无爪牙之利, 筋骨之强, 上食埃土, 下饮黄泉, 用心一也。 (《劝学》)

(2) 长粒、尖粒、圆顶、扁面不一。 (《<天工开物>两则》)

例 (1) 中的“一”意思是专一, 例 (2) 中的“一”意思是一样、统一, 二者都具有形容词性, 作谓语。

4、活用为副词。用作句子的状语。例如:

(1) 一号为文人, 无足观矣。 (《<日知录>三则》)

(2) 而或长烟一空, 皓月千里。 (初中《岳阳楼记》)

例 (1) 中的“一”意思是一旦, 作“号”的状语; (2) 中的“一”意思是全都, 作“空”的状语。

英语倒装句用法小结篇3

一般来说，倒装分为全部倒装和部分倒装，有的倒装是因为语法需要而出现的，有的倒装则是因为结构平衡的需要而出现的。

一、完全倒装（主谓倒装）是指把谓语全部提到主语的前面。例：In a lecture hall of a university in England sits a professor.1.以here, there，now, then引导的句子，要完全倒装。这种句子中的谓语动词通常是不及物动词。如：Here comes the train!/ There goes the bell!注意：若代词作主语，只把该副词提前主谓语序不变。Here he comes./ Here it is.2句首是拟声词或 out , in , up ,away , down 等副词，句子要完全倒装。（注意，这时句子的主语也必须是名词。如果是人称代词，也不能使用倒装结构。）如：Up went the rocket./Up it went.3.介词短语作状语在句首，句子要完全倒装。注意，这时句子的谓语动词通常是不及物动词。如：In the front of the lecture hall sat the speaker.4.表语置于句首，且主语较长或结构较复杂的句子要用全部倒装。如：Gone are the days when we ha nothing to eat.5.so/ neither/ nor 表前面所说的情况也适合于后者，其倒装结构为“so/ neither/ nor+助动词/系动词/情态动词”，这里的主语同前一个句子的主语指的是同一人或物。如：She has finished her homework, so has her brother.She hasn’t gone there, neither/ nor has he.二、部分倒装（助动词倒装）是指把谓语的一部分（助动词）提到主语的前面。例： Never in my life have I seen such a thing.1.用于疑问句中。如：How did you do that? Did you see the film yesterday?

2.if 从句中如有 were(had , should), if 省去后，要部分倒装,把were，had，should提到主语前面

如： If you had come yesterday, you would have seen him.---Had you come yesterday, you would have seen him

3.as 引导的让步状语从句，要部分倒装（表语、状语倒装）。有以下几种形式：(1)副词置于句首

Much as I like it(=Although I like it very much), I will not buy it.(2)动词置于句首

Wait as you may(= Although you may wait), he will not see you.(3).形容词或名词置于句首

Proud as the nobles are(=Although the nobles are proud), they are afraid to see me.Child as he is(=Although he is a child), he can tell right from wrong.注意：如果名词前有形容词修饰时，as引导的倒装句中要保留不定冠词。如： A bad-tempered man as he is(=Although he is a bad-tempered man), he loves me deeply.4.句首为否定词或否定意义的词语时，句子要部分倒装

(not , not only , never , little , seldom , not until, hardly(scarcely), no sooner, not once, at no time,...)Little do we know about him.No sooner had he closed his eyes than he fell asleep.Seldom does he come back on Sundays.Not until he came back did I know about it.5.only 在句首引导状语，或not until 引导的状语在句首，主句要部分倒装。如： Only then did I realize the important of English./ Only when a child grows up does he understand his parents’ intentions.但若only 修饰的是句子的其它成分，则无须倒装

Only socialism can save China.(only修饰句子的主语，仍用正常语序)

6.not only...but also...引导两个并列句，前倒后不倒。如：

Not only does he do well in his lessons, but also he often helps others with their lesso--ns.7.在以often, well, many a time, now and again等方式或频度副词(短语)开头的句子中，要用部分倒装结构

Many a time has John given me good advice./ Often have we made that test.8.用于某些表示祝愿的句子里。May you succeed!

9.so或so引导的短语放在句首,要部分倒装。

So loudly did he speak that even people in the next room could hear him.so„that结构中的倒装。有时要强调so 所修饰的形容词或副词，常将so连同它所修饰的形容词或副词一起提到句首。这时，主句要用倒装结构。如： He runs so fast that he is far ahead of others.---So fast does he run that he is far ahead of others.He is so clever that he can work out all the difficult problems in the book.So clever is he that he can work out all the difficult problems in the book.（全部倒装）

10.状语位于句首表示强调或使句子平衡，或使上下文紧密衔接，句子要部分倒装。

倒装句的用法.在以 here , there , in , out , up , down , away , back , now , then 等副词开头的句子里，如果主语是名词，常用全部倒装。

Out rushed the boys./Then followed three days of heavy rain.若代词作主语，只把该副词提前主谓语序不变。Here he comes./ Here it is..当句首状语是表示地点的介词词组时，也常常引起全部倒装。South of the city lies a big steel factory..以带有否定意义而且修饰全句的词开头的句子，要用“部分倒装”语序(倒装的方法跟变一般疑问句的方法相似，这类常见词有

never , hardly , seldom , not , not only , not until(引导从句时，主句“部分倒装”)，little , rarely , no sooner...than , hardly...when , scarcely...when。例:Never shall I do this again.其中 no sooner...than , hardly...when , scarcely...when 表示“一„„就„„”的意思。no sooner , hardly , scarcely 引出的主句要用“部分倒装”形式的过去完成时，than,when引出的从句用过去时

高中英语数词用法小结篇4

宾补的定义：有些及物动词带了宾语后还需要有一个补足成分才能使句子完整，这个补足成分就叫做宾语补足语。用来说明宾语的行为、特征、状态、身份等。宾语和宾补一起构成复合宾语。主要有下面几种类型：

1.名词（或代词）+名词

She found him a very clever boy.2.名词（或代词）+形容词

He had a strange way of making his class lively and interesting.3.名词（或代词）+副词或介词短语

Last Sunday I saw you out with your sister.To her surprise, she found herself in a different world.4.名词（或代词）+分词（分词短语）

I saw him doing his homework when I passed his window.I was absent-minded when I heard my name called.注意：

在用现在分词或不定式作宾语补足语的动词中，有些只能用现在分词作宾语补足语；有些只能用不定式作宾语补足语；还有的动词既能用现在分词又可用不定式作宾语补足语：

1）、只能用现在分词作宾语补足语的动词有：catch, keep, mind, prevent, stop(阻止)等。She caught her son smoking a cigarette.His words started me thinking.2）、只能用不定式作宾语补足语的动词有：wish, desire, expect, love, prefer, trust, encourage, let, allow, permit, mean, lead, bring, put, hurry, cause, remind, ask, invite, beg, request, worry, advise, persuade, call on, tell, order, command, require, make, force, drive, forbid, warn, help, teach, show, assist, report, bear, wait for, think, take, know, judge, consider, suppose, believe, allow, prove, declare等。

She was seen running away from the scene of the crime.有人看见她从犯罪现场跑开。I saw you put the key in your pocket.我见你把钥匙放进了口袋。5.名词（或代词）+不定式 1).to do The villagers did not allow them to build a factory there.（ask tell beg

force wish

want expect advise permit order persuade）2)省略 to 的不定式

使用不定式作宾语补足语时，不定式符号 to 的取舍问题： 1）、在hear, listen to, let, have, make, see, watch, notice, observe 等动词后的不定式需省去 to。

2）、feel 一词，跟 to be 型不定式带 to；跟 to do 型不定式不带 to。3）、help 一词后的不定式，可带 to，也可以不带 to。6.名词（或代词）+从句

We will make our hometown what your hometown is now.7.常见with+复合宾语有下列几种形式： 1）with＋名词／代词＋形容词

China is a great country, with its capital Beijing.中国是一个伟大的国家，首都是北京。8.结构：主+谓语+ it +宾补+真正宾语 I found it pleasant to be with your family.We think it out duty that we should help the poor.在复合宾语中，宾语通常为名词或代词，但有时也可以用不定式（短语）、动名词（短语）或that从句来充当。这时，应使用先行it代替宾语，而将真正的宾语移到句子的后部，如：

I felt it necessary to speak about our shortcomings.Do you consider it any good trying again? We all thought it a pity that you couldn’t join us.注意：在这种结构中，宾语补足语通常为名词或形容词；常用于这种结构的动词有： feel, find, think, make, take, judge, consider 等。

as用法小结篇5

as是英语中意义广泛、用法灵活且复现率极高的词, 每年高考命题和其他各级命题都会从不同角度对其进行考查。它在词性上有介词、连词和代词等，主要有以下用法。

一、作介词

表示“作为，当作；以„„身份”，其后常接名词。

例如：Johnson works as a doctor.约翰逊（的职业）是个医生。

I like him as a person, but I don’t think much of him as s writer.作为一个普通人，我是喜欢他的，但是作为一名作家，我对他的评价并不高。

Wang Baoqiang’s talents as a film actor were soon recognized.作为电影演员，王宝强的天才很快得到了赏识。

【注意】as和like都可以作介词，但意义不同。as表示“以实际的身份或地位”，like则表示“与„„相似，以与„„相类似的方式”。

例如：He has been playing tennis as a professional for five years.(= he is a professional)他作为一名职业选手已经打了五年网球了。

He plays tennis like a professional.(= he is not a professional but he plays as well as a professional)他打网球就像职业选手一样。

二、作连词

as作连词时，用法比较多，可以引导时间状语从句、原因状语从句、方式状语从句、让步状语从句等。

（一）as引导时间状语从句

表示主句和从句的动作同时发生，并具有延续的含义，意思是“正当„„的时候；随着„„”。

例如：Tom caught sight of Jenny as he was getting off the train.正当汤姆下火车的时候，他看见珍妮了。

As the election approaches, the situation in Libya is getting worse and worse.随着大选的临近，利比亚局势越来越糟糕。

【注意】as与when，while都是引导时间状语从句的从属连词，含义都是“当„„的时候”。但它们有区别：as和when引导的从句可以表示一个短暂性的动作，也可以表示一个持续性的动作；用when时，从句的动作可以与主句的动作同时发生，也可以先于主句的动作发生；但若要表示两个正在发展变化的情况时，一般用as，表示“随着……”。用while时，主句动作与从句动作同时进行或在从句动作过程中发生，从句动词必须是延续性的。

（二）as引导原因状语从句

as一般放在句首，语气较弱，较口语化。

例如：As she has no car, she can’t get the station easily.因为她没有车，去车站不容易。As it is raining, we shall not go the park.由于天在下雨，我们不去公园了。

【注意】as和because，since都可以表示因果关系，但它们有区别：because表示的语气最强，当用于由why提问的句子回答时，必须用because作答；since常常用在书面语中，表示多为对方已知的、或稍加分析便可得知的原因，有时可译作“既然”。

例如：Tom was absent from the opening ceremony because he was ill.因为他生病了，汤姆没有参加开幕式。

--Why can’t I go skiing? 为什么我不能去？--Because you’re too young.因为你太年轻了。

He must have shut the door since he was the last one to leave.他肯定关门了，因为他是最后一个离开的。Since you can’t answer the question, perhaps we’d better ask someone else.既然你不能回答这个问题，我们也许该问问别人。

（三）as引导让步状语从句

as所表示的语气较强，意思是“虽然”，它引导的让步状语从句用倒装语序。倒装语序主要有以下三种形式：

1.形容词或副词+as+主语+（连系动词）be或实义动词。

例如：Rich as he is, he never spends a cent on clothes.虽然他很富有，但他从不花一分钱买衣服。

Much as I admire his courage, I don’t think he acted wisely.我虽然佩服他的勇气，但我认为他这样做是不明智的。

Hard as I studied, I couldn’t catch up with others in class.我虽然努力学习，但赶不上班里其他同学。

2.名词+as+主语+（连系动词）be(注意：句首的名词不带冠词)。

例如：Child as he is, he knows a lot about physics.尽管他是个孩子，但对物理知道不少。3.实义动词+as+主语+助动词，如果没有助动词，则要加上一个do(does或did。例如：Try as he may, he never succeeds.尽管他很努力，但总是不成功。

Search as they would here and there, they could find nothing in the room.尽管到处寻找，但他们在房子里找不到任何东西。

【注意】这种倒装结构中，as可以用though替换，但是不能用although，在运用时要特别注意。

（四）as引导方式状语从句

意思是“如”，“像”，“按照„„的方式”。例如：Remember, you must do everything as I do.记住，你必须按照我做的那样做一切。

（五）as…as…的用法

as...as…意为“和„„一样„„”，表示同级的比较。使用时要注意第一个as为副词，第二个as为连词。其肯定结构为：as+ adj./ adv.+as…；否定结构为：not as/so +adj./ adv.+as…。

例如：This film is as interesting as that one.这部电影和那部电影一样有趣。He can speak English as fluently as a native.他说英语和当地人一样流利。

This dictionary is not as/so useful as you think.这本字典不如你想象的那样有用。【注意】若有修饰成分，如twice, three times, half, a quarter等，则须置于第一个as之前。例如：Your car is twice as expensive as mine.你的汽车比我的贵一倍。

三、作代词

as作代词时，常用于引导定语从句，主要有以下结构： 1.用于the same...as，such...as等结构中

例如：This is the same book as I read last week.这本书和我上周读的那本是一样的。I don’t like such books as he recommends.我不喜欢他推荐的那些书。2.用于“so/as +adj.+ a/an + n.(单数)+ as”结构中

The man is not so/as healthy a man as he was.那个人已经没有从前那么健康了。3.as引导非限制性定语从句时，所指代的内容通常指整个结构；在句子中位置比较灵活，可以在句首、句中或句末。

例如：She is late, as is often the case.她迟到了，这是经常的事。(先行词是整个主句)To shut your eyes to facts, as many of you do, is foolish.视而不见是愚蠢的，好多人都是如此。(先行词是不定式短语)David, as you know, is a famous actor.你是知道的，大卫是著名的演员。【注意】当修饰句子的非限制性定语从句位于句末时，as可以用which来替代。但是，当as从句位于句首或句中时，as就不能用which来替代了。

例如：I live a long way from work, as(which)you know.我住得离工作单位很远，这你是知道的。

As you will find out, I will never let you down.你将会发现，我绝不会使你失望的。Taiwan, as you know, is an inseparable part of China.你们知道，台湾是中国不可分割的一部分。

【注意】as引导非限制性定语从句时，常用于一些固定结构中。如：as we all know/as is known to all大家都知道；as is often the case情况就是这样；as is said/mentioned above/as has been said before如上所述；as can be seen大家看到；as is/was expected/as we expect正如预料；as I can remember我能记住

四、与as相关的固定搭配

as good as差不多，几乎；和„„一样好

as soon as 一„„就„„ as long as只要

as well as同(一样也)；和；还 as far as I’m concerned 据我所知 as if／as though似乎；好像

such…as, such as像„„这样的；比如 as to关于某事物；提到某事物 so as to...为了

as a matter of fact其实；实际上

as a result，as a result of由于„„的结果
