24. as matters stand按目前情况来
说 As matters stand, he does not like to make the plan public.就目前情况而论,他不愿公开那个计划
其基本意思为“与…一样”，其中的第一个as为副词，其后通常接形容词或副词(用原级)，第二个as可用作介词(后接名词或代词)或连词(后接从句)。使用时应注意以下几点。如： (1) 在否定句中，第一个as 也可换成so。如： 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+复数名词+as”。如： You’ve made as many mistakes as I have. 你犯的错误和我犯的一样多。 I haven’t got as much money as I thought. 我不像原来想像的有那么多钱。 其间接形容词时，有时该形容词还可修饰另一名词，但这个名词应带有不定冠词(注意词序)。如： She is as good a teacher as her mother. 她和她妈妈一样是位好老师。 也可说。如：She is a teacher as good as her mother. 但不说。如：She is as a good teacher as her mother. / They are as good teachers as us. (3) 第二个as后接从句时，该as通常为连词，但有时这个as还充当其后从句的主语或宾语，此时该as实为关系代词。如： I gave him as much as he could eat. 他能吃多少，我就给了他多少。 We’ve got food for as many people as want it. 我们的食物，无论多少人吃都够了。 (4) 该结构根据情况可用使用以下修饰语。如：(not) nearly, almost, just, nothing like, exactly, not quite, half, one-ten, twice, three times, 30 per cent等，并且这些修饰语必须置于第一个as之前，而不能置于其后。如： He doesn’t play half as well as his sister. 他演奏的水平不及他姐姐的一半。 This dress is twice as expensive as that. 这件连衣裙比那件贵一倍。 (5) 若第二个as引导一个表示将来意义的从句，则该从句可用现在时表示将来，也可直接使用将来时态。如： We’ll get there as soon as you do [will]. 你一到，我们就到。
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的用法 一）as作副词，表示程度，意为“同样地”。在“as．．．as．．．”，“not as．．．as．．．”结构中的第一个as是副词，作“和／与．．．(不)一样”解。 eg：Jack is as tall as his father．杰克和他的父亲一样高。 e.g. He doesn't speak English as／so fluently as you．他的英语说得不如你流利。注意：as…as可用于表示两个人或物不同性质的比较，表示程度相当或相等，意为“…而…”。 e.g. The prison are as over-crowed as the farmlands are empty. 监狱里人满为患，而土地则无人耕种。 e.g. He was as handsome as his wife was beautiful. 他长得非常英俊，他的妻子长得也非常漂亮。 as…as还可用于表示一个人或物不同性质的比较，表示程度相当或相等，意为“既…又…”。 e.g. She is as kind as honest。她既诚实又善良。 e.g. The problems are as numerous as (they are) trivial。问题又多又繁琐。 二）as作介词 1．作“如，像”解。 eg：They got united as one man．他们团结得像一个人一样。 2．作“充当，作为”解。 eg：As a writer，he was famous．作为作家，他是很有名的。 三）as作连词，常用来连接主句和状语从句。 1．引导时间状语从句，作“当．．．的时候”解，有“随着．．．”之意，与while意义相近，强调两个动作同时发生；或某事一发生，另一事立即发生。 eg：He shouted aloud as her ran along．他一边往前跑，一边高声地呼喊。 e.g. I was startled as he opened the door．他一开门，我吓了一跳。 as作连词，相当于when。 eg；As a little boy (When he was a little boy)he began to learn to play piano．他小时候就开始学弹钢琴。 2．引导原因状语从句，作“因为，由于”解，与because的用法相近。 eg；I must stop writing now，as I have rather a lot of work to do．我必须停笔了，因为我还有许多工作要做。 3．引导方式状语从句或比较状语从句，作“正如，(如)像”解。例 eg：As in your country，we grow wheat in the north and rice in the south．正如(像)你们国家一样，我们在北方种小麦，在南方种大米。(方式状语从句) e.g. When at Rome，do as Romans do．入乡随俗。(方式状语从句) “as…, so…”结构意为“正如…也…，犹如…一样”，表示的是比拟关系。As引导的是含有比拟意义的方式状语从句，so相当于“in the same way, in the same proportion”，引导主句。该结构有以下几个特点： 1）as前可加just，表示强调；2）as从句可以居前，也可以居后，在前时用逗号隔开，在后时不用；3）as从句居前时，主句常用倒装结构；4）“as…, so…”结构可用“what…, that…”
EXCEL经典用法大全 ='面(地质)'!A18 此处就是面(地质)的那页的A18行 =SUM(D130:K130) 求和 =SUM(C130*L130) 剩积 01、如何在已有的单元格中批量加入一段固定字符？ 例如：在单位的人事资料，在excel中输入后，由于上级要求在原来的职称证书的号码全部再加两位，即要在每个人的证书号码前再添上两位数13，如果一个一个改的话实在太麻烦了，那么我们可以用下面的办法，省时又省力： 1）假设证书号在A列，在A列后点击鼠标右键，插入一列，为B列； 2）在B2单元格写入：="13" & A2 后回车； 3）看到结果为13xxxxxxxxxxxxx 了吗？鼠标放到B2位置，单元格的下方不是有一个小方点吗，按着鼠标左键往下拖动直到结束。当你放开鼠标左键时就全部都改好了。若是在原证书号后面加13 则在B2单元格中写入：=A2 & “13” 后回车。 02、如何设置文件下拉窗口的最下面的最近运行的文件名个数？ 打开“工具”，选“选项”，再选“常规”，在“最近使用的文件清单”下面的文件个数输入框中改变文件数目即可。若不在菜单中显示最近使用的文件名，则将“最近使用的文件清单”前的复选框去掉即可。 03、在EXCEL中输入如“1-1”、“1-2”之类的格式后它即变成1月1日，1月2日等日期形式，怎么办？ 这是由于EXCEL自动识别为日期格式所造成，你只要点击主菜单的“格式”菜单，选“单元格”，再在“数字”菜单标签下把该单元格的格式设成文本格式就行了。 04、在EXCEL中如何使它象WORD一样的自动定时保存文件？ 点击“工具”菜单“自动保存”项，设置自动保存文件夹的间隔时间。如果在“工具”菜单下没有“自动保存”菜单项，那么执行“工具”菜单下“加载宏...”选上“自动保存”，“确定”。然后进行设置即可。 05、用Excel做多页的表格时，怎样像Word的表格那样做一个标题，即每页的第一行（或几行）是一样的。但是不是用页眉来完成？ 在EXCEL的文件菜单－页面设置－工作表－打印标题；可进行顶端或左端标题设置，通过按下折叠对话框按钮后，用鼠标划定范围即可。这样Excel就会自动在各页上加上你划定的部分作为表头。 06、在Excel中如何设置加权平均？ 加权平均在财务核算和统计工作中经常用到，并不是一项很复杂的计算，关键是要理解加权平均值其实就是总量值（如金额）除以总数量得出的单位平均值，而不是简单的将各个单位值（如单价）平均后得到的那个单位值。在Excel中可设置公式解决（其实就是一个除法算式），分母是各个量值之和，分子是相应的各个数量之和，它的结果就是这些量值的加权平均值。 07、如果在一个Excel文件中含有多个工作表，如何将多个工作表一次设置成同样的页眉和页脚？如何才能一次打印多个工作表？ 把鼠标移到工作表的名称处（若你没有特别设置的话，Excel自动设置的名称是“sheet1、sheet2、sheet3.......”），然后点右键，在弹出的菜单中选择“选择全部工作表”的菜单项，这时

which的用法大全 1、在后置的非限制性定语从句中代替上文出现的事物或情况（单数或复数）。 2、在问句中作为疑问代词，在名词从句中作为连接代词用，其含义为“哪个、哪些”。 3、如果非限制性定语从句的先行词不是指主句内容，而是指具体的人、时间、地点，则不用which。 [解题过程] 这里主要讲解一下在定语从句中的用法： 一、关系代词that 和which 在定语从句中作主语和宾语，放在先行词和定语从句之间，起联系作用。指物时，一般情况下可互换。如： Here is the pen that/which you lost yesterday.(that/which 指物作宾语) A plane is a machine that/which can fly.(that/which 指物，作主语) He is the most careful boy that I know.(that 指人,作宾语) The man that works in this room is a chemist.(that 指人,作主语) 二、that,which 在从句中作主语时，不能省略。作宾语时在口语中和非正式问题中经常省略。如上例1 和中的that,which 都可省略。 三、关系代词在主语从句中作主语时，从句的谓语动词的人称和数须和先行词一致。 Wheat is a plant that/which is grown in the north of China. 四、在定语从句中，关系代词that 和which 指物时，一般没有区别，但下列几种情况中不能互换： 只能用that 的情况： a)先行词为 all,everything,nothing,anything,little 等不定代词时（something 后也可用which）：Is there anything (that) I can do for you in town That’s all (that) I know. b) 先行词被序数词所修饰时： The first thing (that) we should do is to work out a plan. c) 先行词被形容词最高级所修饰时： This is one of the most exciting football games (that) I have ever seen.

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从句用陈述语气。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. 他张开嘴好像要说什么。 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 用法归纳和练习题 一、as作副词，表示程度，意为“同样地”。在“as．．．as．．．”，“not as/so．．．as．．．结构中的第一个as是副词，作“和／与．．．(不)一样”解。 Jack is as tall as his father． He doesn't speak English as／so fluently as you． 二、as作介词。 1．作“如，像”解。They got united as one man． 2．作“充当，作为”解。eg：As a writer，he was famous． 三、as作连词，常用来连接主句和状语从句。 1．引导时间状语从句，作“当．．．的时候”解，有“随着．．．”之意，与while意义相近，强调两个动作同时发生；或某事一发生，另一事立即发生。eg： He shouted aloud as her ran along．他一边往前跑，一边高声地呼喊。 I was startled as he opened the door．他一开门，我吓了一跳。 as作连词，相当于when。eg； As a little boy (When he was a little boy)he began to learn to play piano． 2．引导原因状语从句，作“因为，由于”解，与because的用法相近。eg； I must stop writing now，as I have rather a lot of work to do． 3．引导方式状语从句或比较状语从句，作“正如，(如)像”解。例eg： As in your country，we grow wheat in the north and rice in the south．正如(像)你们国家一样，我们在北方种小麦，在南方种大米。(方式状语从句) When at Rome，do as Romans do．入乡随俗。(方式状语从句) Leave it as it is. 保持原状，不要动它。 4．引导让步状语从句，作“虽然，尽管”解。这时从句常用倒装语序，即把从句中的表语、状语或动词原形放在as之前。eg； Strange as it may seem，it is true． 尽管这事看上去很奇怪，但却是真的。 Try as he might，Tom could not get out of the difficulties． 不管怎样努力，汤姆还是摆脱不了困境。 Child as he is, he know s a lot. Much as I like you, I will not marry you. 我虽然很喜欢你，可是不愿与你结婚。 四、as作关系代词。 1．引导限制性定语从句，用在“such．．．as”,“the same．．．as”，“as．．．as” “so… as”等结构中，常译作“像．．．一样的人(或物)”，“凡是．．．的人(或物)”。例eg： He wished to be such a man as Lei Feng was．他曾希望做一个像雷锋那样的人。 My hometown is no longer the same as it was．我的家乡再也不像过去一样了。2．引导非限制性定语从句，用来指代它前面的整个句子(即先行句)。这个分句可以位于句首、句中或句末。 As is well known，oceans cover more than 70％of the earth．
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'thave 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: We 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 dan ces as she si ngs 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, si nee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 she has been ill perhaps she'll need some help. 她由于生病可能需要些帮
as 用法详解 1.用作连词，表示让步 (意为：虽然，尽管)，要用于倒装句，且倒装后位于句首的名词通常不用冠词 (等于though, 但语气稍弱)。如： Child as[though]he was, he did quite well. 他虽是个孩子，但已干得很不错。 2.用作关系代词，主要用法有二。如： (1)用在such, same, as等之后，引导限制性定语从句。如： This is thesame watch as I lost. 这块表跟我丢失的那块一样。 Such men as (=Those men who) heard of him praised him. 听说过他的人都赞扬他。 (2)单独用作关系代词，引导非限制性定语从句，可放在主句之前 (常译为：正如)或之后 (常译为：这一点)，且主从句之间一般要用逗号隔开。如： He was absent, as is often the case. 他缺席了，这是常有的事。 As was expected, he succeeded at last. 正如我们所料，他终于成功了。 3.用来表示目的，下面两种句子结构都可以。如： 仔细写以便把每句话都写清楚。 正：Write carefully so as to make every sentence clear. 正：Write so carefully as to make every sentence clear. 4.在正式文体 (尤其是文学体裁)中，as后可用倒装语序表示“…也一样”这类意思 (现代英语通常so表示这一用法)。如： He travelled agreat deal, as did most of his friends. 他去过许多地方旅游，他的多数朋友也是一样。 He plays the piano, as does his mother. 他会弹钢琴，他母亲也会。 注：用作连词，表示原因 (参见because)，表示时间 (参见when)。 5.用于 as if as though, 意为“仿佛”、“似乎”。两者一般可通用 (但注意不能说 as although)。用法上注意几点：
第一部分a bit和a little的用法区别 相同之处： 1. a bit和a little都表示“稍微”、“有点”之意,都可作程度副词,修饰动词、形容词(包括形容词化的现在分词和过去分词)、副词、比较级。在肯定句中可以互换。例如: Will you please turn down the radio a bit/a little? (修饰动词) She’s a bit/a little afraid of the teacher.(修饰形容词) The patient feels a bit/a little better to-day.(修饰比较级) He did his homework a bit/a little care-lessly.(修饰副词) 2. a bit和a little都有some“一些”之意,后接不可数名词。例如: I’ve got only a little/a bit of money with me today. I’m afraid I can’t help you. 3. for a bit和for a little意思相同,相当于for a while或for a short time,可互换。例如: I’m going to sleep for a bit/a little. Let’s rest for a bit/a little. 不同之处： 1. a little可用作形容词,直接修饰不可数名词;而 a bit不能用作形容词,修饰名词时,其后须加上of,构成“a bit of+n.”结构。例如: Please give me a bit of paper. He knows a bit of French. 但是,当a little修饰的名词前有this,that以及所有格等限定词时,也要用a little of结构。例如: I want to drink a little of that wine. 2. a bit可构成“a bit of+不定冠词+名词”,而a little则不能。例如:
