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。
As与When、While的比较
作“在-------期间，当----的时候”引导时间状语从句.注意与when、while的用法区别。
①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. 如:

③while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。如:Work while you work. Play while you play.

如:They helped the old as much as possible.
I don't speak English so/ as well as she does.
5.引导让步状语从句,表示虽然,尽管等,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。模式为:

尽管这事看上去很奇怪，但却是真的。

五）含as的固定词组的用法

注意：当主语后面跟有as much as引导的从属结构式，随后的动词依主语本身的单复数而定。例：

6．so／as far as I know作“就我所知”解，在句中作插入语。eg：

10.inasmuch as由于；因为
Double session were instituted inasmuch as the school was crowded.
11、as well as 也 ,又和...一样
The father，as well as his sons，is gonging to enroll。
六）其他
1、Because,since,as的比较。
在because，since，as这三个从属连词中，以because语势最强，since次之，as又次之。Because 通常表示“新信息”,”即表示一种未知的原因，而since/as则表示已知原因。所以在回答why-问句时要用because-分句，而不用since-/as分句。在because分句之前可用否定词或其他修饰词，这种分句之前还可以用某些并列连词，而since-/as-分句不可以。例：
I went to the state university chiefly because the tuition was cheaper。
She didn't want to go to Afraic,probably because the weather is too hot。
2、as……as结构
这种模式的基本结构是：as+形容词或副词原级+as-分句。
John is as bright as Bob。
This parcel is as heavy as that one。
这种结构否定形式:John is not as bright as Bob。
在带有as……as结构的句子中，通常是主句主语和as-分句主语不同而比较项目相同，比如John和Bob就是两人进行精明程度比较。此外，带有as……as结构的句子也有可能主语相同，而比较项目不同。例如：
The girl is as brilliant as she was beautiful.这姑娘既漂亮又聪明。
He is not so wise as he is witty。他为人风趣，但有欠明智。
也有可能两个主语和两个比较项目都不相同，即两个不同人或物就不同的方面进行比较。例如：This swimming pool isn’t twice as wide as that one is long。这个游泳池的宽度并没有那个游泳池长度的两倍。
as……as结构还有一种变体形式，as+形容词原级+名词词组+as-分句。例如：
George is as efficient a worker as Jack。
I don’t want as expensive a car as this.
显然这是由as……as结构的基本模式转换而来：
George is a worker as efficient as Jack。
I don’t want a car as expensive as this.
两种形式区别：用变体形式，名词的意义受到强调;用基本形式，形容词的意义受到强调。比较：
I haven’t seen as old a car as this for years.
I haven’t seen a car as old as this for years.
在上述变体形式中，嵌入在as……as结构中的名词词组通常是“不定冠词+单数可数名词”或者“零冠词+不可数名词”。至于“零冠词+复数可数名词”作如此用法则比较罕见。例如：I don’t smoke cigarettes as expensive as these.
?I don’t smoke as expensive cigarettes as these.(罕见)
as as的用法
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用法
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
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
