Thirty-five years after computer scientists at UCLA linked two bulky computers using a 15-foot gray cable, testing a new way for exchanging data over networks, what would ultimately become the Internet remains a work in progress.
University researchers are experimenting with ways to increase its capacity and speed. Programmers are trying to imbue Web pages with intelligence. And work is underway to re-engineer the net-work to reduce spam and security troubles.
(46)
All the while threats loom: critics ware that commercial, legal and political pressures could hinder the types of innovations that made the Internet what it is today.
Stephen Crocker and Vinton Cerf were among the graduate students who joined UCLA professor Len Kleinrock in an engineering lab on Sept. 2, 1969, as bits of meaningless test data flowed silently between the two computers. By January, three other "nodes" joined the fledgling network.
(47)
Then came e-mail a few years later, a core communications agreement called TCP/IP in the late 70s, the domain name system in the 80s and the World Wide Web—now the second most popular application behind e-mail—in 1990.
The Internet expanded beyond its initial military and educational domain into businesses and homes around the world.
Today, Crocker continues work on the Internet, designing better tools for collaboration. (48)
And as security chairman for the Internet’s key oversight body, he is trying to defend the core addressing system from outside threats.
He acknowledges the Internet he helped build is far from finished, and changes are in store to meet growing demands for multimedia. (49)
Network providers now make only "best efforts" at delivering data packets, and Crocker said better guarantees are needed to prevent the skips and unexpected pauses now common with video.
Cerf, now at MCI Inc., said he wished he could have designed the Internet with security built-in. Microsoft Corp., Yahoo Inc. and America Online Inc., among others, are currently trying to retrofit the network so e-mail senders can be authenticated—a way to cut clown on junk messages sent using spoofed addresses.
(50)
Many features being developed today wouldn’t have been possible at birth given the slower computing speeds and narrower Internet pipes, or bandwidth, Cerf said.
选项
答案
瑟夫说,因特网刚出现时,计算机处理速度较慢,带宽较窄,因此我们今天开发出的很多功能在当时根本无法实现。
解析
本句是简单句,句子为主系表结构:Many features wouldn’t have been possible。分词短语being developed today作定语,修饰features;介词短语given the slower computing speeds and narrower Internet pipes,or bandwidth作句子状语;given此处为介词,意为"考虑到",这里按照句子各部分逻辑关系以因果关系译出即可。the slower computing speeds和narrower Internet pipes是名词短语,因为要断句翻译,因此需进行词性转换,译成动宾结构:计算机处理速度较慢,带宽较窄。at birth原意为"在出生时",但按照原意翻出,语句不通顺,句中因为前面提到了因特网刚出现时,因此将at birth译成"当时"既忠实原文,又表达流畅。
