Unit 5 OmissionOmission is a technique opposite to amplification. True, a translator has no right to subtract any meaning from the original work. But it does not follow that he should refrain from omitting any words at all in translation. In fact, one of the marked differences in syntax between English and Chinese is the disparity in wording. What is regarded as a natural or indispensable element in one language may be regarded as superfluous or even “a stumbling block” in the other.Ⅰ. Omission in English-Chinese TranslationGenerally speaking, omission in English-Chinese translation is used to achieve the effect of succinctness, especially in the cases of English pronouns and functional words such as the article, the preposition, the conjunction, etc.1.Omitting the PronounPronouns are more frequently used in English than in Chinese. Therefore, when translated into Chinese, many English pronouns may be omitted so as to conform the rendering to the accustomed usage of Chinese expression.·He put his hands into his pockets and then shrugged his shoulders.他将双手放进口袋,然后耸了耸肩。

translation动词形式近年来,随着国际交流的日益增多,翻译已经成为了一项非常重要的技能。
在进行翻译的过程中,我们可能需要用到不同的动词形式,因此掌握这些形式非常有必要。
下面就来逐一讲解一下。
1. Translate"Translate" 是最基础的翻译动词,它的意思是“翻译”。
在英文中,它经常用于表示将一种语言转换成另一种语言。
我们可以使用它构成各种时间和时态的形式,比如:- I translate (我翻译)- He translated (他翻译过)- We have translated (我们已经翻译过)- They will translate (他们将要翻译)2. Interpret"Interpret" 这个动词与 "translate" 类似,不过它更专注于口译、翻译上的口头表达。
它的意思是“口译、口头翻译”。
下面是一些例子:- She interpreted for the tour group. (她为旅游团做口译) - The interpreter struggled to translate the complex speech. (口译员努力翻译这篇复杂的演说)3. Render尽管 "render" 这个动词也有很多其他的含义,但在翻译中,它的意思是“翻译、诠释、表达”。
"Render" 更加形象和抽象,往往在诗歌和文学翻译中使用。
一些例子:- The translator rendered the poem into modern English. (翻译家将这首诗歌翻译成了现代英文)- The novel was rendered beautifully into a graphic novel.(这部小说被很好地转化成了一本图像小说)4. Paraphrase"Paraphrase" 的意思是“释义、改写”。

在翻译过程中,由于两种语言在语法和表达习惯上的差异,我们有时必须改变原文某些词语的词类或句子成分才能有效地传达出原文的准确意思。
汉语是一种动词显著的语言,因此英译汉的词类转换最重要的一项就是将英语的各种词类转换成汉语动词。
此外,词类转换也包括各种词类转换成名词、形容词、副词等操作方法技巧。
句子成分的转换包括主语与宾语之间的相互转换;主语转换为谓语、状语等。
由于汉语句式中动词的使用频率大大超过英语,因此,要使译文符合英语的习惯表达法,就得将汉语中的大量动词转换为名词、形容词、介词、副词等。
除动词转换之外,汉译英也涉及其他一些词类的转换。
Practical Translation Training1. English-Chinese TranslationEnchantment of the South Sea IslandsThe mighty Pacific washes the shores of five continents-North America, South America,Asia,Australia,and Antarctica. Its waters mingle in the southeast with the Atlantic Ocean and in the southwest with the Indian Ocean. It is not on the shores of continents,nor in the coastal islands,however, that the soul of the great Pacific is found. It lies far out where the fabled South Sea Islands are scattered over the huge ocean like stars in the sky.Here great disturbances at the heart of the earth caused mountains and volcanoes to rise above the water. For hundreds of years tiny coral creatures have worked and died to make thousands of ring-shaped islands called atolls.The air that sweeps the South Sea Islands is fragrant with flowers and spice. Bright warm days follow clear cool nights, and the rolling swells break in a never-ending roar on the shores. Overhead the slender coconut palms whisper their drowsy song.When white men fast came to the Pacific Islands,they found that the people living there were like happy children. They were tall men and beautiful women who seemed not to have a care in the world. Coconut palms and breadfruit trees grew at the doors of their huts. The ocean was filled with turtles and fish,ready for the net. The islanders had little need for clothing. There was almost no disease.Cruel and bloody wars sometimes broke out between neighboring tribes,and canoe raids were sometimes made on nearby islands. The strong warriors enjoyed fighting. Many of the islanders were cannibals,who cooked and ate the enemies they killed. This was part of their law and religion. These savages,however,were usually friendly,courteous,and hospitable. Some of the early explorers were so fascinated with the Pacific Islands that they never returned to their own countries. They preferred to stay.Notes and Explanations1. the South Sea Islands南太平洋诸岛,South Sea南半球诸海洋的,南太平洋的2. wash v. 波涛冲洗、拍打3. mingle with混合,汇合;注意此句中方位的表达顺序4. fabled a.虚构的,富有神奇色彩的5. atoll n. 环状珊瑚岛,环礁6. worked and died 繁衍、死亡7. rolling swells 滚滚巨浪;注意此句翻译中所采用的词类转换的技巧8. drowsy song催眠曲9. filled with turtles and fish, ready for the net 鱼盆成群,张网可得10. canoe raid 乘独木舟进行攻击;注意此句中将被动语态转为主动的翻译方法11. cannibal n.吃人的人2.

第7章本章阅读前提在阅读本章内容之前,大家最好先熟悉下面这些章节的内容:第1章“通用网络概览”,第3章“以太网”,第4章“令牌环网和FDDI”和第6章“LAN交换技术”。
此外,大家也应该对十六进制与二进制,十六进制与十进制,十进制与二进制数的相互转换很熟悉,这并不仅阅读本章的前提条件,而且还是CCIE考试的一个要求。
别的一些桥路转发技术本章导读1. 4种主要的不可路由协议是什么?2. CRB与IRB的区别是什么?3. BVI的功能是什么?4. 在SRB环境中,终端工作站之间的数据通讯路径是由什么设备决定的?5. 浏览器的功能是什么?6. RIF的功能是什么?7. 令牌环号需要多少位来指定?8. SRB环境中的最大跃距数是多少?9. RSRB和SRB的区别是什么?10. 在SRT环境中,一个数据帧能否进入SRB域是由什么决定的?实践部分请参考附录F。
和路由转发工作在网络层不同,桥路转发是在OSI/RM模型的数据链路层上工作着的。
第6章“LAN交换技术”讨论的是透明桥路的概念,这一章将要讲述的是通过网络传输不可路由协议的一些技术,具体地说包括桥路转发的类型,如何将路由器配置为桥路,以及更为常用的如何与大型机交换SNA数据等。
从以前的情况来看,桥路转发部分在CCIE笔试中占有很大的比重,因此,这一章的内容需要全面深入的理解以通过CCIE的考查。
不可路由的协议尽管绝大多数的桥路应用场合应用的都是SNA,但是这并不是桥路的唯一用途。
别的一些不可路由协议只能工作在OSI/RM模型的数据链路层上。
下面列出的就是一些不可路由的协议的情况:♉ DEC LAT (DEC的局域传输协议)♉ DEC MOP (DEC的维护操作协议)♉ NetBIOS (网络输入输出系统)♉ SNA (系统网络架构)NetBIOS在网络中传输的时候,最常用的是封装成TCP/IP的形式,此外还有就是封装成IPX的形式。
如果NetBIOS没有封装成网络层协议的形式,而是在LLC2子层上运行,那它就需要通过桥路进行传输。
NetBIOS也称为NetBEUI (NetBIOS扩展用户接口)。
关键概念不可路由协议主要包括SNA,NetBIOS,DEC LAT和DEC MOP。
并发性路由与桥路转发Cisco的CCIE考试规划将并发性路由与桥路转发(CRB)也列为了考试内容之一。
CRB 采用单台路由器在一组接口上通过桥路转发一个可路由的协议,同时在另一组接口上对该协议通过路由进行转发。
CRB和集成路由与桥路(本章后面将要讨论的IRB)不同,在CRB中,路由和桥路是在不同的接口上进行的。
CRB的工作情况图7.1以IP为可路由协议对此进行了解释。
图中左边部分是路由转发接口,而右边则是透明桥路转发接口。
CRB不会对不可路由的协议造成影响,这些协议是通过桥路组命令来转发的。
图7.1CRB环境中的路由和桥路转发过程两组接口之间的数据只有满足了下面的这两个条件之一才能够在相互之间进行交换:♉ 桥路接口做了相应的网络层配置(也就是用IP进行了配置)。
♉ 路由接口也作为桥路接口加入到了桥路组中去。
在CRB工作环境中,如果接口e0和e1同时也在bridge-group 1 组中(比方说,允许NetBEUI 进行桥路转发),路由器就也能通过桥路转发IP数据。
为了达到此目的,还需要配置一条外部桥路路由命令。
关键概念CRB是并发性的在通过一组接口进行路由转发的同时又在另一组接口上进行桥路的转发。
其中一组接口的数据是禁止进入另一组接口中去的。
CRB的配置下面就是对图7.1中的路由器进行配置的情况:interface Ethernet0ip address 10.1.0.1 255.255.255.0interface Ethernet1ip address 10.1.1.1 255.255.255.0interface Ethernet2no ip addressbridge-group 1 (assigns the interface to transparent bridge group 1)interface Ethernet3no ip addressbridge-group 1 (assigns the interface to transparent bridge group 1)bridge crb (enables CRB functionality)bridge 1 protocol ieee (bridge 1 will use the spanning tree protocol)bridge 1 route ip (specifies that IP traffic on bridge 1 will be routed)下面这条命令则可以用来下是CRB接口的统计情况:rtr# show interfaces crb集成路由与桥路转发(IRB)CRB并没有将路由和桥路两个转发过程合并在一起,而集成路由与桥路转发(IRB)则利用一台路由器将路由和桥路的转发过程集成在同样的接口上完成。
这一过程是通过对桥路虚拟接口(BVI)的配置来是实现的,BVI就是桥路接口到路由接口这个过程的体现。
要成功的进行IRB的配置,BVI的数目必须要和桥路组的数目相匹配(也就是bridgegroup 1 和bvi1需要匹配)。
IRB的工作情况图7.2以IP为路由协议解释了IRB BVI的概念情况。
左边的接口就是路由转发接口,而右边的则是透明桥路接口。
在IRB过程中,不可路由协议是不受影响的,它们是通过桥路组命令进行转发的。
图7.2IRB环境中的路由和桥路转发过程桥路网段e2和e3都是用bvi1中配置的IP网络来代表的。
每个网段中的主机和网络中别的主机进行网络层通讯的时候都是以bvi1作为其默认网关的。
在启动IRB之后,网络层协议默认情况下是通过桥路进行转发的。
因此,该协议的路由转发还需要用一条外部路由命令进行配置(将像上个例子中的bridge 1 route ip)。
关键概念IRB将路由接口和桥路接口结合到了一起。
BVI是桥路组中的一个虚拟接口,它能允许数据从桥路组中通过路由进入路由组中去。
IRB的配置下面就是对图7.2中的路由器进行配置的情况interface Ethernet0ip address 10.1.0.1 255.255.255.0interface Ethernet2no ip addressbridge-group 1 (assigns the interface to transparent bridge group 1)interface Ethernet3no ip addressbridge-group 1 (assigns the interface to transparent bridge group 1)interface BVI1 (creates an interface to represent bridge group 1 to therouting process)ip address 10.1.1.1 255.255.255.0bridge irb (enables IRB functionality)bridge 1 protocol ieee (bridge 1 will use the spanning tree protocol)bridge 1 route ip (specifies that IP traffic on bridge 1 will be routed)下面这条命令则可以用来下是IRB接口的统计情况:rtr# show interfaces irb源路由桥路(SRB)纯源路由桥路(SRB)与透明桥路以及相关的一些衍生物,如LAN交换机,IRB和CRB是完全不同的。
SRB算法是上个世纪80年代中期,IBM为了使多个令牌环LAN网段与IBM大型机之间建立桥路关系而提出的。
和令牌环一样,SRB现在也成为了IEEE 802.5规范的一部分。
SRB在设计的时候是以很大型的网络为基础的。
IBM的规范指出,任何两台设备之间不能有超过8个的令牌环和7个桥路存在(这也就是所谓的7个跃距的限制)。
IEEE 802.5的规范现在则允许在两台设备之间存在14个的令牌环和13个桥路。
Cisco通常情况下采用的是IBM 的规范。
SRB的工作情况SRB是一个很贴切的名称,它说明在通过令牌环与桥路网络与通讯对象主机建立连接的时候,如果要预选出一条最佳的路由,源主机是必需的。
在选出最佳路由之后,SRB就会将这一信息封装到每个令牌环数据帧的报头中去。
这方面的内容请参考图7.3以加深大家的理解。
图7.3SRB网络是由交替配置的令牌环和桥路组成的如果Host A不知道它与目的主机B之间的路由,它会首先假设目的主机是本地的,往它的本地令牌环网段(Ring 1)发出一个测试数据帧。
如果测试数据帧从目的主机返回的话,那通讯就可以开始了。
如果测试数据帧没有返回,源主机就会发送一个浏览器数据帧以确定目的主机是与哪一个远程网段相连的(这个例子中是Ring 4)。
在浏览器数据帧和任何别的发送到远程令牌环去的数据帧中,它们的组/个体(group/individual)位必须要设置成1。
这是MAC地址的第1位,也称作多播位。
每个接收到浏览器数据帧的桥路都会将此数据帧通过它们的端口转发出去,并且还会将它们的路由转发信息添加到浏览器数据帧中去。
在图7.3的例子中,Host B接收到每一个浏览器数据帧的时候,它就能从此数据帧的信息中知道数据帧是通过什么样的路由到达它这个目的主机的,而且也就知道了返回Host A的两条路由是什么。
利用这些信息,Host B会为每个浏览器数据帧向Host A发送一个应答信息。
根据这些应答信息,Host A就获知了两条通往Host B去的路由:♉ Ring 1, Bridge 1, Ring 2, Bridge 2, Ring 4♉ Ring 1, Bridge 4, Ring 3, Bridge 3, Ring 4现在Host A就必须要选择一条它与Host B之间的路由。
由于IEEE 802.5标准并没有提供路由选择的方法,大多数的主机都是以第一个返回的浏览器数据帧中包含的路由作为自己的选择。
Host A现在就将所选的路由放置到其令牌环数据帧的路由信息字段(RIF)中从而开始与Host B的通讯了。
只有数据帧是发往远程LAN(这里是令牌环)的时候RIF 才会出现在令牌环数据帧中。
RIF字段的工作情况能够构造一个RIF字段并不会对SRB的配置有什么帮助,但是这却对CCIE笔试有很大帮助,因为考试中会要求大家能够构造和读懂RIF从而正确的回答相应的问题。
