指出一下，好象没有specifical这个词，specific的副词形式是specifically但形容词还是specific。这几个词中文意思都差不多，都有特别，特殊的意思，不过英文释义还是有区别的。special强调的是与其它不同，specialized则有专门之意，往往是有技术性的，specific指特定的，有针对性的。有意思的是special和specific在牛津和麦克米伦上的解释相反。专门的应该用special，specialized在这点上意思也相近，dedicated意思差得比较远，是形容人专心，专一的。

n. 特效药，细节; adj. 特殊的; <罕>详细而精确的; 明确的; 特效的;

从特别的、特殊的意思上讲这两个词的用法有什么区别吗？

意思就不一样 specially 专门地 特别地 specifically 特定地,明确地 especially 尤其

新年决心(New Year"s resolution) Today is the first day of 2007(so yesterday was the last day of 2006,haha), it seems that almost everyone is busy making his or her new year"s resolution or sum-up. However I, with a mess-up mind, can"t remember all the things exactly in terms of months, and therefore I just consider the past 2006 as a year when I took two TOEFLs, won a lawsuit in my volunteering career (although it is not a real recovering legally), found the first job during my lifetime, met a particular one whom I mistook as the right person and then knew him well after hurt, decided to give up the dream of going to the United States to further my study......maybe the list should be endless, but right now, my memory is limited. Since past can never equal with future, so just let pass-by be pass-by and that looking forward to a more splendid perspective would be a better choice. Simplification and nature is what I am pursuing after these years and I will do my utmost to keep up this style of life. I will try to be happy everyday and, as I"ve witten in ,my space, smile all the time, no matter what comes and what happens! This is a general idea of my 2007 life. To be more specifical, I made the following plans to do within the whole year: 1.Keep fit! It has been a long time since my last time to do some exercise. Doing sports is not only a way to lose weight, but more important, to stay healthy. Maybe I will do some exercise on weekends with several friends or go to a gym to learn body mechanics or yoga. (keep my weight no more than 48kg is my goal! ) 2.Stick to learing English! Since the dream of becoming a lawyer seems so close to me, why can"t the deam of being an English teacher like Vincent realize? 3.Work harder and harder in my job position. Good beginning is half done! Stepping the first footprint into the society, I don"t just want a job. What I really want is a career. The importance of the first job, what"s more, the choosen field, is evident. I won"t leave any regret to the future Grace when I looking back from my old. 4.Learn to be more tolerant and considerate. Thank you for all my friends" care. You have companied me these days and bear my bad temper. I know that I owe you all the love and help. In the next year, I will try to be mature! 5.Last but of course not least, be happier than the past. Being alone doesn"t certainly mean lonely. I"d like to enjoy this single style in 2007! I just can plan the above things. If there is any modification or supplement, I will add in at any time. 好像有点多，你自己再裁减一部分吧 另外一篇Hello, Hellen! This year is over. To welcome the new year, I make my New Year"s resolutions. Let me tell you about it. First, I want to help my mother do some housework. Because my mother is very tired, I want to do something for her. I can help her wash my own clothes and clean the house, sweep the floor and so on. Second, I want to ski in Beijing. Because skiing can make me strong and healthy. I also want to listening to the music. I like singing. I also like to collect CDs. Listening to popular music makes me relax. Third, I will get on well with all my students in a new year. And I will work hard at all my subject. I hope I can get good marks in the exam. What do you think of my New Year"s Resolutions?

Some persons have been appointred to assume official positions just because they are from some specificaliiy favored families. They have not been properly educated by competent teachers, they have not been examined by the government, so no one knows that whether they have the proper talent for the positions assunmed by them. And in respect to their morals or values, they have not been guaranteed by thier families or senior members in their families. However, with the existance of all of the above-mentioned shortcomings of these people, our central government shill recklessly trust them and appoints them to assume official positions. 白话文翻译就是：一些年轻人被任命为官员，不是因为他们的文化水平或才能，而仅仅是因为他们特殊的家庭背景。他们没有受过什么教育，也没有经过正式的考试考查，他们的家庭长辈也不敢保证他们的文化素养和道德水准。但即使是这样，这些人却依然被朝廷任命为官员。

歙 xi安徽的一个地名 歙县歙县[1]，中国黄山市下属的一个县，徽州六县之一，徽州文化的发祥地之一，位于安徽省南部，古代为徽州府治所在地，是徽州文化及国粹京剧的发源地，也是徽商的主要发源地，是文房四宝之徽墨、歙砚的主要产地，于1986年被授予国家历史文化名城称号。歙县历史悠久，素有“东南邹鲁”、“文化之邦”之美誉，是徽文化的重要发祥地和徽商的起源之处。钟灵毓秀的古徽州大地曾孕育了朱熹、毕升、渐江、王茂荫、吴承仕、黄宾虹、陶行知等一代宗师，开创了新安画派、新安医学、徽派建筑、徽派盆景等诸多流派，歙砚、徽墨、徽剧、徽菜等更是蜚声中外。

歙 读she 第一声

18个复韵母有:ai、ei、ui、ao、ou、iu、ie、ve、er、an、en、in、un、vn、ang、eng、ing、ong。复韵母：ai、ei、ui、ao、ou、iu、ie、ue、er。前鼻韵母：an、en、in、un、ün。后鼻韵母：ang、eng、ing、ong。复韵母是由两个或者是三个元音相互结合而产生的韵母，这种韵母就叫做复韵母，复韵母这种复合元音并不是两个或者三个元音相互拼凑而成就可以的，这种算得上是一种分配重组。因为两个或者三个元音在重组后，会得到一个新的固定的音组，而这种音组是可以同时带动嘴巴、舌头与耳朵，它们都与单元韵有同感，而并不是我们简单理解的简单相加即可。18个复音韵母发音方法：1、ai（挨）：发音时，先发a的音，然后滑向i，气流不中断，读音轻短。2、ei（诶）：发音时，先发e的音，然后滑向i，气流不中断，嘴角向两边展开。3、ui（威）：发音时，u的发音轻短，然后滑向ei，嘴形由圆到扁。4、ao（凹）：发音时，先发a的音，然后舌尖后缩，舌根向上抬，嘴形拢成圆形，轻轻的滑向o。5、ou（欧）：发音时，先发o的音，嘴唇渐收拢，舌根抬高，口型由大圆到小圆。6、iu（优）：发音时，先发i，然后向ou滑动，口型由扁到圆。7、ie（也）：发音时，先发i，再发e，气流不中断。8、üe（虐）：发音时，先发ü的音，然后向e滑动，口型由圆到扁。9、er（耳）：发音时，舌位居中发e的音，然后舌尖向硬腭卷起，两个字母同时发音。10、an（安）：发音时，先发a的音，然后舌尖逐渐抬起，顶住上牙床发n的音。前鼻韵母an、ian、uan、üan的发音。11、en（恩）：发音时，先发e的音，然后舌面抬高,舌尖抵住上牙床，气流从鼻腔泄出，发n的音。前鼻韵母en、uen、in、ün的发音12、in（音）：发音时，先发i的音，然后舌尖抵住下门齿背，舌面渐至硬腭，气流从鼻腔泄出，发n的音。13、un（温）：发音时，先发u的音，然后舌尖抵住上牙床，接着发n的音，气流从鼻腔泄出。14、ün（晕）：发音时，先发ü的音，然后舌头上抬，抵住上牙床，气流从鼻腔泄出，发n的音。15、ang（肮）：发音时，先发a的音，然后舌根抵住上软腭，气流从鼻腔泄出，发后鼻音尾ng的音。16、eng（嗯）：发音时，先发e的音，然后舌尖抵住下牙床，舌根后缩抵住软腭发ng音，气流从鼻腔泄出。17、ing（鹰）：发音时，舌尖触下齿龈，舌面隆起至硬腭，鼻腔共鸣成声。18、ong（翁）：发音时，先发o的音，然后舌根后缩抵住软腭，舌面隆起，嘴唇拢圆，鼻腔共鸣成声。

: 歙[xī] [shè] [Shè] [字义]: [xī] 1.收敛,吸进:“将欲～之,必固张之”。2.古同“翕”,和洽。[shè]1.〔～县〕地名,在中国安徽省。...

有两种读法xi，第一声1.吸，吸进2.收敛 例句：~动还有一个读音she第三声1.地名。~县，在今安徽省东南

复韵母的全称是复元音韵母，它一共有十三个，这是十三个复韵母分别是：ai 、ei、ao、ou、ia、ie、iao、iou、ua、uo、uai、uei、üe，复韵母是韵母结构中的其中一个分类，另外两个分类是单韵母和鼻韵母。在我们的普通话拼音当中，一共有着39个韵母，其中包括13个复元音韵母(也就是我们所说的复韵母)，10个单元音韵母(也叫做单韵母)，以及十六个鼻韵母。复元音韵母是由2到3个元音合并形成的韵母，而单元音韵母则就是指代由单元音充当的韵母，至于鼻韵母，就是带有鼻辅音的韵母。扩展资料我们汉字的拼音是由声母和韵母结合构成的，只有声母与韵母结合在一起，才能够构成完整、正确的汉语音节。根据发音部位的不同，我们一般将声母分为7个大类，第一类是双唇音，共含有3个声母。第二类是唇齿音，共含有1个声母；第三类是舌尖前音，含有3个声母；第四类是舌尖中音，含有4个声母；第五类是舌尖后音，含有4个声母；第六类是舌面音，共含有3个声母；最后一类是舌根音，共含有3个声母。

这是一个多音字：歙（shè），歙县，地名，在安徽省歙（xī）,吸气

复韵母8个：ai、ei、ui、ao、ou、iu、ie、üe。前鼻音韵母：指拼音中以“n”结尾的，如：an、en、in、un、ün5个；后鼻音韵母：指拼音中以“ng”结尾的，ang、eng、ing、ong4个。韵母是一个中国汉语音韵学术语，汉语字音中声母、字调以外的部分。旧称为韵。韵母由韵头（介音）、韵腹（主要元音）、韵尾三部分组成；按韵母结构可分为单韵母、复韵母、鼻韵母。汉语字音中声母、字调以外的部分。旧称为韵。韵母又可以分成韵头（介音）、韵腹（主要元音）、韵尾三部分。如“娘”niáng的韵母是iang，其中i是韵头，α是韵腹，ng是韵尾。每个韵母一定有韵腹，韵头和韵尾则可有可无。如“大”dà的韵母是α，α是韵腹，没有韵头、韵尾；“瓜”guā的韵母是ua，其中u是韵头，α是韵腹，没有韵尾；“刀”dāo的韵母是ao，其中α是韵腹，o是韵尾，没有韵头。

复韵母有：ai、ei、uo、uai、uei、ie、iao、iou、ao、ou、ia、ua、üe。复韵母的全称是复元音韵母，共十三个。复韵母指的是由两个或三个元音结合而成的韵母，应视为一个完整的语音整体，发音时不能间断。复韵母的分类复韵母可以分为前响复元音韵母、后响复元音韵母、中响复元音韵母。在汉语拼音中有13个复韵母，分为9个二合元音和4个三合元音。9个二合元音分别为：ai、ei、ao、ou、ia、ie、ua、uo、üe，4个三合元音分别为：iao、iou、uai、uei。二合元音分前响复韵母、后响复韵母两类，三合元音是中响复韵母。前响复元音韵母发音时，口腔肌肉放松，韵腹a、o、e发得清晰、响亮、音值稍长，后面的i、u(o)是韵尾，发得轻、短、模糊，只表示舌位滑动的方向。后响复元音韵母发音时，前一个元音i、u、ü是韵头，读得轻、短而紧张，后一个元音是韵腹，读得清晰、响亮、时值较长。两个元音必须读成一个整体。中响复元音韵母发音时，韵头轻、短，韵尾含混、音值不固定，韵腹清晰、响亮、音值较长。在前响二合元音之前，加上i、u的舌位动程，原来的前响元音仍然保持，便构成中响复韵母。

楼主给那么少财富，太抠了！1、10.19.1.123/8，因为网络位是8位，所以子网掩码为：255.0.0.0，所以网络号为：10.0.0.0，广播地址为：10.255.255.255。因为10.19.1.123为该网络的网络地址，且是标准的A类地址（网络位是8位），所以主机范围为：10.19.1.123-10.255.255.255。2、192.168.3.98/24，因为网络位是24位，所以子网掩码为：255.255.255.0，所以网络号为：192.168.3.0，广播地址为：192.168.3.255。因为192.168.3.98为该网络的网络地址，且是标准的C类地址（网络位是24位），所以主机范围为：192.168.3.98-192.168.3.255。3、172.23.76.52/16，因为网络位是16位，所以子网掩码为：255.255.0.0，所以网络号为：172.23.0.0，广播地址为：172.23.255.255。因为172.23.76.52为该网络的网络地址，且是标准的B类地址（网络位是16位），所以主机范围为：172.23.76.52-172.23.255.255。4、202.103.24.68/28，因为网络位是28位，所以子网掩码二进制为：11111111.11111111.11111111.11110000，化为十进制为：255.255.255.240；由子网掩码二进制可以看出：前3段都是1，所以只需计算最后1段即可：68的二进制是：01000100和子网掩码最后1段（11110000）进行逻辑与计算（全1为1，见0为0）后得网络号：01000000，化为十进制是64，所以该网络的网络号为：202.103.24.64。将网络号01000000后4位置为1得：01001111，化为十进制得：79，所以该网络广播地址为：202.103.24.79，所以主机范围为：202.103.24.64-202.103.24.79。28位网络位是C类的变长子网掩码。5、IP190.45.91.5后面没跟有网络位，所以190开头的IP默认是B类地址，子网掩码为：255.255.0.0，所以网络号为：190.45.0.0，广播地址为：190.45.255.255，主机范围为：190.45.91.5-190.45.255.255。

掩码：255.255.255.24011111111 11111111 11111111 00000000C类地址从第四位开始划分子网，也就是从00000000开始划子网。按照每个子网最多9台主机的需求，2的3次幂8<9台机器，2的4次幂=16>9满足要求。所以主机位保留4位。也就是11110000划分16个子网，每个子网掐头去尾，有效地址14个满足需求。各子网地址：子网 , 有效的主机 , 广播地址 199.6.5.0 , 199.6.5.1 到 199.6.5.14 , 199.6.5.15 199.6.5.16 , 199.6.5.17 到 199.6.5.30 , 199.6.5.31 199.6.5.32 , 199.6.5.33 到 199.6.5.46 , 199.6.5.47 199.6.5.48 , 199.6.5.49 到 199.6.5.62 , 199.6.5.63 199.6.5.64 , 199.6.5.65 到 199.6.5.78 , 199.6.5.79 199.6.5.80 , 199.6.5.81 到 199.6.5.94 , 199.6.5.95 199.6.5.96 , 199.6.5.97 到 199.6.5.110 , 199.6.5.111

引入原码反码和补码的目的就是为了解决减法问题，因为计算机cpu的运算器中只有加法器，要把减法转化成加法来计算。举个例子，a表示十进制数“+16”，b表示十进制数“-19”，把这两个数的原码直接相加，得：a＝＋16（a）原＝00010000b＝－19（b）原＝1001001100010000+10010011————10100011其结果符号位为1是负数，其数值位为100011，即等于十进制数“-35”，这显然是错的结果。再比如，十进制数“+16”与“+19”的原码直接相减，得：00010000-00010011————11111101结果为“-125”，这又是错的。但是引入补码后，加减法都可以用加法来实现，如“-16+11”的运算：11110000+-16的补码0000101111的补码————11111011-5的补码如果是“-16-11”，那么就转化为加法运算“-16+（-11）”11110000+-16的补码11110101-11的补码————111100101-27的补码在字长为8位的系统中，最高位所产生的进位被自然丢弃，运算结果的机器数为11100101，是-27的补码形式，结果正确。顺便告诉你一些其它的东西：1.二进制数中，两数的补码之和等于两数和的补码。2.补码＝反码+13.反码＝原码除符号位外其它数值取反（即该数的绝对值取反），即“0”变“1”，“1”变“0”。4.任何正数的原码反码补码的形式完全相同（即都是自身，不变）5.在计算机中，有符号的数都是采用补码来表示的。6.计算的时候，符号位也参与运算。

首先看他的子网掩码 网络位应该是 22位，前18位是一样的故子网可以有 16个 其中的3个子网为 a:192.168.112.0/22 ； b: 192.168.128.0/22 ；c:192.168.134.0/22 很明显 192.123.124.5 属于子网a，192.123.134.5 属于子网c

逻辑没有加，只有逻辑与，首先对位，对应位全为1则结果为1，否则为0，故结果为00000001.如果是二进制数相加，则就是加法，1+1=2时则进位，故结果为11110000.

IP地址范围限定在192.168.10.17-192.168.10.31之间说明共有16个主机地址，而且没有主机地址全0和全1的情况，只要用4位二进制就能表示了。32位的子网掩码中前28位为1，后4位为0，二进制表示为255.255.255.240
