高中英语as用法全归
纳
as的用法灵活，词义繁多，特别是在复合句中更能体现其用法的多样性和灵活性，但如果同学们能正确掌握as的词性和词义，是不难掌握其用法的。
一、as用作关系代词引导定语从句
1. as 引导非限制性定语从句，一般不指代某个具体的名词或代词，而是代表整个主句或主句的一
部分。这种从句可放在主句之前，也可以放在主句之后，有时还可以放在主句的中间。如：
As is reported in the newspapers, talks between the two countries are making progress. 正如在报纸上所报道的，两国间的谈判有所进展。
Grammar is not a set of dead rules, as has been said above. 如上所说，语
法不是一套死条文。
Spiders are not insects, as many people think, nor even nearly related to them. 蜘蛛不是昆虫，尽管许多人都这样认为，它甚至与昆虫几乎没有联系。
2. as 引导限制性定语从句，主要用于the same…as（与……相同），such…as（像……一样），as…as（与……一样）。如：She knew he felt just
the same as she did. 她知道他的感受和她一样。
Such a man with a good temper as Mr. Li is easy to get along with. 像李先生这样好脾气的人是容易相处的。
He smokes as expensive a cigarette as he can afford. 他抽一种他买得起的最贵的烟。
二、as作为从属连词引导时间状语从句
表示“随着……”或
者“当……的时候”或“一边……一边”，强调主句的动作和从句的动作同时发生。如：
I saw him as he was getting off the bus. 当他下公共汽车的时候我看见了他。
The boy was singing a popular song as he was bicycling. 这男孩边骑车边唱歌。
As she grew older, she became less active. 当她长
大一点的时候，就变得不那么活泼了。
As time goes by, I come to realize that it is so important to learn English.
三、as作为从属连词引导原因状语从句
as 引导的原因状语从句常放在主句前，表示“因为，由于”。如：
As she is a model teacher, she sets a good example to others. 因为她
是一名模范教师，她给其他人树立了一个好的典范。
As he wasn’t ready in time, we went to the cinema without him.
由于他没有及时准备好，我们就去看电影了，没有等他。
三、as作为从属连词，引导让步状语从句
as引导让步状语从句比较特别，它要求将表语
和状语或谓语的一部分倒装。如：
Old as he is, he is still full of energy. 尽管年纪大了，但他依然精力充沛。
Try as she may, she never succeeds. 尽管她很努力，但总是不成功。
Much as I admire Mr. Wang as a poet, I don’t like him as a man. 尽管我喜欢王先生的诗歌，但我不喜欢他的为人。
注：当倒装后置于句
首的名词为单数可数名词时，习惯上不带冠词。如：Boy as he was, he was made king. 尽管他还是个孩子，却被立为国王了。
四．as 用作从属连词，引导方式状语从句
例如：
●When you are in Rome, do as the Romans do.
●Tell it as it is.
●Leave things as they are.
●You look good as you
are.
●The house looks ugly as it is now; it needs improving.
●I would like to sell the house as it is.
●The exhibition worked out very well as planned.
●The result of the competition was very bad as expected.
五、与其他词搭配使用构成从属连词引导从句
1. as if / as though。表
示“好像，仿佛”，引导表语从句或方式状语从句。如：
It looks as if / as though it is going to snow. 看起来要下雪啦。
He looks as if / as though he had seen a ghost. 他的脸色看起来好像他看见了鬼。
He talks as if /as though he knew everything about it. 他说话的口气好像他已经全部
都知道了。
2. as /so long as。“只要”，引导条件状语从句。如：
As /So long as you can keep away from them, you will be safe. 只要你能远离他们，你就安全了。
I’m happy as long as you are happy. 只要你幸福，我就感到幸福了。
3. as /so far as。表示“在……的范围内”，引导限制状语从句。多用于下列
结构：as /so far as I know （据我所知），as /so far as I can see, as /so far as I’m concerned（依我看）。如：As /So far as I know, the couple have been abroad for about five years. 据我所知，这对夫妇已经出国约五年了。
There’s only one thing to be done now, as far as I can see. 依我看。现在只有一件事情要做。
4. as soon as。表示
“一……就”，引导时间状语从句。如：

He started as soon as he received the news. 他一得到消息就出发了。
5. as to…=about…= concerning=with respect to…=regarding…关于
例如：Can you give me
some advice as to how to keep a good figure?
6. so as to…(不放句首)=in order to do…为了…
例如：The students are studying hard so as not to fail the exam.
六．as 可以用作介词“作为”
●The boy acts as a guide during the course of this trip.
●As a child, I used to go
hunting with my grandfather.
●My cousin works as a nurse in a hospital.
●As a teacher, I will do whatever I can to help you.
总之，由于as的用法复杂，同学们在学习时一定要注意比较其在不同句子中的作用，判断其连接的是什么样的从句，多做一些关于相关练习，这样便可掌握其用法了。
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.
高中英语语法：It的完整用法精讲 it可用作人称代词、指示代词、先行词及引导词等。 1. 人称代词it，是第三人称单数中性，代表前文已提到过的一件事物。如： 1）That vase is valuable. It's more than 200 years old. 那个花瓶很珍贵，它有200多年的历史。 2）I love swimming. It keeps me fit. 我喜欢游泳，它能使我保持健康。 当说话者不清楚或无必要知道说话对象的性别时，也可用it来表示。如： 3）It's a lovely baby. Is it a boy or a girl? 宝宝真可爱，是男孩还是女孩？ it可用来指代团体。如： 4）The committee has met and it has rejected the proposal. 委员会已开过会，拒绝了这项建议。 it用以代替指示代词this, that.如： 5）--- What's this? --- It's a pen. —这是什么？—是一支钢笔。 6）--- Whose book is that? --- It's Mike's. —那是谁的书？—是迈克的。 2. 指示代词it，常用以指人。如： 7）Go and see who it is. 去看看是谁。 8）--- Who is making such a noise? —是谁发出这样的吵闹声？ --- It must be the children. —一定是孩子们。 3.虚义it无指代性，常用作没有具体意义的主语，出现于表示天气、气候、温度、时间、地点、距离等意义的句子中。如： 9）It is half past three now. 现在是三点半钟。 10）It is six miles to the nearest hospital from here. 这里离最近的医院也有六英里。 11）It was very cold; it snowed and grew dark. 天气很冷；天下着雪，渐渐地变黑了。 it也常用来表示一般的笼统的情况。如： 12）It's awful—I've got so much work I don't know where to start. 糟透了——我有这么多工作要做我不知从何开始。 13）How is it going with you? 你近况如何？ 14）Take it easy. 不要紧张。 it也常用于下列结构： 15）It looks as if the college is very small. 看起来这个学院很小。 16）It seems as though our plan will be perfect. 似乎我们的计划很完善。 17）It's my turn. 该轮到我了。 it也常用于某些习惯用语中作宾语，各该习惯用语有具体意义，但it并无具体意义。如：cab it 乘车catch it 受责，受罚come it 尽自己分内come it strong 做得过分walk it 步行make it 办成take it out of somebody 拿某人出气 4. 先行词it. it充当形式主语或形式宾语，本身无意义，只起一种先行引导的作用，先行词不重读。后面的真正主语或真正宾语通常是不定式结构、-ing分词结构或名词性从句。 （1）用作形式主语
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. (连接两个状语) 中国的天气和加拿大一样随季节的变化而变化。 The teacher as well as the students enjoys listening to English songs.（连接两个主语）老师和学生都爱听英语歌曲。 He grows flowers as well as vegetables. 他既种菜也种花。 She shares (in) my troubles as well as my joys. 她与我同甘共苦。 They have a flat in town as well as in the Country. 他们在城里有一套公寓，在乡村还有一所房子。 We are repairing the roof, as well as painting the walls. 我们既油漆墙壁，又修房顶。 It is important for you as well as for me. 这对我很重要，对你也很重要。 Lily as well as her parents is very fond of classical music. 不但莉莉的父母，而且连

1.表示不同人或物同一性质的比较，意为“……和……一样……" Michael is as bright as George(is). 迈克尔和乔治一样聪明。 2. 表示同一个人或物不同性质的比较，意为“既……又……” Alice works as happily as(she)plays(happily). 艾丽丝愉快地工作，尽情地玩。 3. 用于表示两个人或物不同性质的比较，表示程度相同或相当，意为“……且/而……”。 He was as handsome as his wife was beautiful. 他长得非常英俊，他的妻子也长得非常漂亮。 He was as experienced as his brother was green. 他经验丰富，而他兄弟却涉世未深。 使用时应注意以下几点： 1. 在否定句中，第一个as 也可换成so： He doesn’t study as [so] hard as his brother. 他学习不如他弟弟努力。 2. 在该结构的两个as之间通常接形容词或副词的原级，但若涉及数量或程度，可用“as much+不可数名词+as”和“as many+可数名词复数+as” ：
高考英语语法知识之It 的用法总结 1．It is + 被强调部分+ that ... 该句型是强调句型。将被强调的部分放在前面，其它部分置于that之后。被强调部分可以是主语，宾语，状语。强调的主语如果是人，that可以由who换用。 如果把这种句型结构划掉后，应该是一个完整无缺的句子。这也是判断强调句型与其它从句的方法。 It was they that (who) cleaned the classroom yesterday. It was in the street that I met her father. 2．It was not until + 被强调部分+ that ... 该句型也是强调句型。主要用于强凋时间状语，译成汉语＂直到．．．才．．．＂，可以说是not ... until ... 的强调形式。 It was not until she took off her dark glasses that I realized she was a famous film star. = Not until she took off her dark glasses did I realize she was a famous film star. = I didn’t realize she was a famous film star until she took off her dark glasses. 3．It is clear ( obvious, true, possible,certain....) that ..... 该句型中it 是形式主语，真正的主语是that 引导的主语从句，常译为＂清楚（显然，真的，肯定．．．）＂是主语从句最常见的一种结构。 It is very clear that he’s round and tall like a tree.= That he’s round and tall like a tree is very clear. 4. It is important ( necessary, right, strange, natural...) that ... 由于主句中的形容词不同，that 后的从句中要用虚拟语气（should + 动词原形），should 可以省去。 It is important that we (should) learn English well. It is necessary that he (should) remember these words. 5. It is said (reported, learned....) that ... 该句型中的it 仍是形式主语，真正主语是that 引导的主语从句。该结构常译为＂据说（据报道，据悉．．．）＂。It is said that he has come to Beijing. 6. It is suggested ( ordered ... ) that ... 主句中的过去分词是表示请求，建议，命令等词时，that后的从句要用虚拟语气（should + 动词原形），should 可以省。常译为＂据建议；有命令．． It is suggested that the meeting ( should ) be put off. It was ordered that we ( should ) arrive there in two hours. 7.

A.一般现在时 1．一般现在时的构成 一般现在时主要用动词原形来表示。主语是第三人称单数时，动词后面要加-s或-es。 “我’为开头做称呼的是第一人称 ‘你’怎么怎么样是第二人称 ‘他她它’是第三人称 第三人称就是第三人称转述。 例：小兰对妈妈说：“我要出去玩了” 第三人称：小兰对妈妈说，她要出去玩了。 第三人称，就是说是叙述性质的，没有人的语言，是旁白在记叙！ 以我的角度说，就是第一人称； 以和你说的角度说，就是第二人称； 站在事情外说事情，他怎么怎么样，那就是第三人称了 They want good jobs. 他们想要好的工作。 The coat matches the dress. 外衣和裙子很相配。 This work does not satisfy me. 这项工作我不满意。 Do you understand? 你懂了吗? 2．一般现在时的用法 ①一般现在时的基本用法 a. 表示现在习惯性的动作或存在状态 He always takes a walk after supper. 晚饭后他总是散散步。 Everyone is in high spirits now. 现在大家都情绪高涨。 b. 表示客观事实或普遍真理 The sun rises in the east and sets in the west.
