as if 用法归纳 1． as if 从句的作用as if一般可由as though来代替。 引导表语从句，可在look, seem等系动词后。如： He looked as if / though he was ill. 他看起来好像生病了。It seems as if it is going to rain.看来好像要下雨了。 引导方式状语从句。如： I remember the whole thing as if / though it happened yesterday. The child talked to us as if he were a grown-up. 那个小孩跟我们讲话就像个大人一样。 2． as if 从句的语气及时态 ①as if从句用述语气。当说话者认为句子所述的是真实的或极有可能发生或存在的事实时， It sounds as if it is raining. 听起来像在下雨。 He talks as if he is drunk. 从他说话的样子来看他是醉了。 ②as if从句用虚拟语气。当说话人认为句子所述的是不真实的或极少有可能发生或存在的情况时， 表示与现在事实相反，谓语动词用一般过去式。如： You look as if you didn’t care. 你看上去好像并不在乎。When a pencil is partly in a glass of water, it looks as if it were broken． 表示与过去或与谈话时间为止发生的事实相反，谓语动词用
“had +过去分词”。如： He talked about the Great Wall as if he had been there before.说起长城来好像他以前去过那里。 The girl listened as if she had been turned to stone.女孩听着，一动也不动，像已经变成了石头。 表示与将来事实相反，谓语动词用“would / could / might + 动词原形”。如： He opened his mouth as if he would say something. 他开嘴好像要说什么。 It looks as if it might snow. 看来好像要下雪了。 3． as if从句中的省略。如果as if 引导的从句是“主语+系动词”结构，可省略主语和系动词等成份，这样as if 后就只剩下名词、不定式、形容词（短语）或动词-ing形式等。 He acts as if (he was) a fool. 他做事像个傻子。 He paused as if (he was going) to let the sad memory pass. The girl left the room hurriedly as if (she was) angry. 女孩匆忙离开房间，好像生气的样子。 From time to time, Jason turned round as if (he was) searching for someone. 词汇学习 1. A smelly gas came out of the cracks.
As的用法 as...as 的用法比较多，中间除了加形容词、副词，名词也可以的（请看下面第2点）： as...as的结构： as + 形容词或副词原级+ as 1）在否定句或疑问句中可用so… as。 He cannot run so/as fast as you. 2）当as… as 中间有名词时采用以下格式。 as +形容词+ a +单数名词 as + many/much +名词 This is as good an example as the other is. I can carry as much paper as you can.. 3）用表示倍数的词或其他程度副词做修饰语时，放在as的前面。 This room is twice as big as that one. Your room is the same size as mine. 4) 倍数+ as + adj. + as<=> 倍数+ then + of This bridge is three times as long as that one. This bridge is three times the length of that one. Your room is twice as large as mine. Your room is twice the size of mine. the population of our students was _that of theirs. A twice as large as B twice as much as A twice as large as 是对的。 这是倍数/分数表达的词序问题。“A 是B的几倍/几分之一。。。”的正确词序是：A+be 倍数/分数+as +形容词/+as B 此外，与population搭配的形容词是large/great/big，如：a big/large/great population，或者the population is big/large/great,而不能用much或者many。
as well as的用法 曲靖市第二中学 as well as后接动词到底该用什么形式，这是一比较复杂的问题，归纳起来有以下几点值得注意： 一、as well as构成同级比较结构，意为“和…… 一样好”。 第一个as是副词，第二个as是连词，引导一个状语从句，表示同级比较。 在否定句中可用not so well as代替not as well as。 He speaks English as well as a native speaker. 他讲的英语是和英语是母语的人一样好。 He can operate the machine as well as I do. 他操作这台机器和我一样熟练。 He speaks English as well as she. 他说英语说得跟她一样好。 She plays every bit as well as the men. 她打得一点不比男人们差。 He doesn’t play half so well as his sister. 他演奏的水平不及他姐姐的一半。 He sings as well as, if not better than, Mary. 他要是唱歌不比玛丽唱得更好，但至少也是一样好。 She cooks as well as her mother (does). 她烧菜和妈妈一样好。 二、as well as用作连词，连接两个并列的同等成分，其意义为“不但……而且……”，“既……又……”，这时相当于not only ... but also ...。 它所连接的部分既可以是单词、短语，也可以是句子。 在A as well as B的结构里，语意的重点在A，不在B。翻译时要特别注意。The girl is lively as well as healthy.（连接两个表语）这女孩既健康又漂亮。 He can speak Spanish as well as English. (连接两个宾语) 他不但会说英语，而且会讲西班牙语。 In China, as well as in Canada, the weather changes from season to season.

as的用法 as这个词看似简单，但用法却是很多的，对它的正确理解关系到英语应用能力的提高，因此我们有必要对其用法和搭配进行详细阐述。 一、as作介词 1. 区别as和like as作为介词时，可以表示“像……”，这时它可以和like互用；as还可以表示“以……身份”或“作为……”，“当作……”，但like不能。 e.g. I) They lived and fought among the people as “fish in water”. (as相当于like) II) As a scientist, he was dedicated to (致力于) the truth. (这里不可以用like) II) They talked as old friends. (他们确乎是老朋友。) They talked like old friends. (他们像老朋友一样。) 2. as引导的介词短语在句中可以充当： a) 宾语补足语 e.g. I) She spoke of me as her dearest friend. II) The plan struck me as very much worthwhile. III) Y ou mustn’t think of me as (being) unhappy. b) 主语补足语 e.g. I) She is well-known as being very cheerful. II) He is sometimes portrayed as belonging to another century. III) That picture is looked upon as very valuable. 常用于这类结构的动词有：accept, consider, describe, elect, interpret (理解), look upon, perceive, recognize, refer to, regard, see, strike, take, think of, treat, view等等。 二、as作连词 1. 作“当……的时候”,引导时间状语从句。注意与when、while的用法区别。 A. when作"当……的时候"解,可以指较短的(一点)时间,也可指一段时间。 e.g. I)When he was at college, he could speak several foreign languages. II) When the clock struck twelve, all the lights in the street went out. B. while常表示一段较长的时间或一个过程,强调主句谓语动词与从句谓语动词同时发生。 e.g. Work while you work. Play while you play. C. 但属下列情形时,只用as, 而不用when或while。 1) 用于表示同一个人的两种动作交替进行,指“一边……,一边……”。 e.g.I)The girl dances as she sings on the stage. II) He looked behind from time to time as he went forward. 2)表示两个同步发展的动作或行为,译为“随着……”。 e.g. I) As time went on / by, she became more and more worried. II) As children get older, they become more and more interested in the things around them. 3)表示两个短促行为或事件几乎同时发生。 e.g. I) I thought of it just as you opened your mouth.
As的用法归纳 as的用法很多，又比较复杂，本文就此作一归纳： 一、作副词，意为“相同地”，“同样地”。例如： They don’t have as many airplanes. 他们没有同样多的飞机。 二、作连词， 1. 引导时间状语从句 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: (1). when作“当……的时候”解，可以指较短的(一点)时间,也可指一段时间。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。例如: John was having his dinner when I saw him. 当我看到约翰的时候，他正在吃饭。 She can write only when the baby is asleep. 只有婴儿睡着的时候，她才能写作。 (2). while常表示一段较长的时间或一个过程，强调主句谓语动词与从句谓语动词同时发生或在从句动作过程中发生。例如: W e must strike while the iron is hot. 要趁热打铁。 While we were reading, the teacher came in. 我们正在读书的时候，老师走了进来。 (3). 但属下列情形时，只用as, 而不用when或while。 ①用于表示同一个人的两种动作交替进行,指“一边……,一边……”。例如: The girl dances as she sings on the stage.那个女孩在舞台边唱歌边跳舞。 He looked behind from time to time as he went forward. 当他朝前走时，不时地向后看。 ②表示两个同步发展的动作或行为,译为“随着……”。例如: As time went on / by, she became more and more worried. 随着时间的流逝，她变得越来越焦虑。 As he grew older, he became more intelligent. 随着他年龄的增长，他变得更有才智了。 ③表示两个短促行为或事件几乎同时发生。例如: I thought of it just as you opened your mouth. 恰好在你开口时，我想到了它。 Just as the flying worm hit her face, she gave a loud cry. 恰巧在飞虫撞到她脸上时，她大哭起来。 2. 引导原因状语从句 as，because，since都可以表示因果关系，连接原因状语从句，含义是“因为，由于”，但它们有区别：because表示的语气最强；as一般放在句首，语气较弱，较口语化；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： I do it because I like it. 我做这件事是因为我喜欢。 Since many of the customers work during the day, Billy has to collect the money at night. 因为许多顾客白天上班,所以毕利只好晚上去收钱。
as的用法总结 as是英语考试中用得比较多的一个词，也是很多学生反映较难掌握的一个词。as的词性较多，用法也较复杂，因此掌握该词会对英语学习很有帮助。下面笔者就对as的用法作一个简单的归纳。 一、as作为从属连词，可以引导下列从句： 1、as引导时间状语从句，意为“正当……的时候”、“一面……一面……”、“随着……”，从句可放主句之前或主句之后。 As I was coming here, I met your brother. As he walked on, he felt himself getting more and more tired. 【知识拓展】：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：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；用while时，从句的动作为一过程，主句动作与从句动作同时进行或在从句动作过程中发生；用as时，主句和从句的动作同时发生，具有延续的含义。例如： It was snowing when he arrived at the construction site.他到达工地时，天正在下雪。 He was watching TV while his mother was cooking.他母亲做饭时他在看电视。 You will grow wiser as you grow older.你会随着年龄的增长而越来越聪明。 2、as引导原因状语从句，意为“由于”大多位于主句之前，偶尔在前或后。 As this question is of great importance, we will discuss it once again. Water, as it occurs in nature, is never very pure. We couldn‘t send the children to school as life was very hard in those days.【知识拓展】：as, because, since都可以表示因果关系，连接原因状语从句，含义是“因为，由于”，但它们有区别：because表示的语气最强；as 一般放在句首，语气较弱，较口语化；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： He will succeed because he is in earnest.他一定会成功，因为他很认真。 Since you are so sure of it he’ll believe you.既然你对此如此有把握，他会相信你的。 As rain has fallen, the air is cooler.因为下过雨，空气比较清爽。 3、方式状语从句，意为“如同”、“按照……的方式、样子、办法”。As 从句总跟在主句之后。 You must try to hold the tool as I do. 象我那样拿住工具。 Leave things as they are. 让那些东西保持原样。 3、as引导让步状语从句，意为“虽然”，多在主句之前，且多用倒装。（应将从句主要成分的形容词、副词、原形动词、不加冠词的单数名词
