The traditional telephone system relied on circuits to transmit communications — that is, a dedicated connection from each party on a call to the other. There were advantages to that model, especially because having a dedicated circuit meant that telephone calls were very reliable, but it was not a terribly flexible system. The Internet, by contrast, was designed for flexibility. Bandwidth permitting, every member of a household can use it simultaneously, with multiple different devices, in dozens of ways, for many purposes, all at once.

思考题：

The telephone system is mentioned to show that___.

A.oral communication is outdated

B.it is a strong and reliable model

C.flexibility makes Internet desirable

D.circuits can serve multiple purposes

词汇突破：

circuits 电路

transmit 传输

— that is, 也就是说

a dedicated connection 专用的链接

a dedicated circuit 专线

terribly(非常)

this dish is terribly delicious. (这道菜太好吃了!)

这就类似于汤神说的：清晰地一塌糊涂、

flexible 灵活的

by contrast, 相比较而言(找出不同点)、

by comparison (找出共同点)

flexibility 灵活性

Bandwidth 带宽

simultaneously 同时

句子解析：

句：

The traditional telephone system relied on circuits to transmit communications — that is, a dedicated connection from each party on a call to the other.(同位语解释前面的句子)

参考译文：传统的电话系统依靠电路来传输通信，即从每个呼叫方和另一方之间有专用的连接。

第二句：

There were advantages(主干) to that model, especially because having a dedicated circuit meant that telephone calls were very reliable, 状语 but it was not a terribly flexible system.(并列主干二)

参考译文：这种模式有其优点，尤其是专用电路意味着电话呼叫非常可靠，但它并不是一个非常灵活的系统。

第三句：

The Internet,by contrast, was designed for flexibility.

参考译文：相比之下，互联网为灵活性而设计。

第四句：

Bandwidth permitting,(状语) every member of a household can use it simultaneously, with multiple different devices, in dozens of ways, for many purposes, all at once.(状语)

参考译文：带宽允许的情况下，每个家庭成员都可以同时使用，接入多个不同设备，为了许多目的，以数十种方式，全都同时进行。

思考题解析：

The telephone system is mentioned to show that___.

这是一个例证题!

电话系统被提及来展示_____

(首先，电话系统就是为了引入，后面的互联网，所以直接锁定答案：

C. flexibility makes Internet desirable

(灵活性让互联网受欢迎)

当然如果你们这个意识，那就来排除其他三个：

A. oral communication is outdated

(口头交流已经过时)

没有提及!排除!

B. it is a strong and reliable model

(这是一种坚固且可靠的模式)

这就是例证题常见的错误!例子说明的不是例子本身，而是对应的结论。

举例：

何凯文老师是英语老师，都四十了还在勤奋地写公号。相比较而言，马云老师四十的时候就已经辞职了，人和人的区别还是很大的。

何凯文老师被提及来说明______

(A) 何凯文老师很勤奋。

(B) 人和人是有区别的。

答案只能选B吧!

例证题的答案：来自例子前后的结论。

D. circuits can serve multiple purposes

(电路可以有多种用途)

应该是互联网能完成多用途，而不是电路，

D选项错误。

背景：本文的作者是一位网络安全专家。他常年研究互联网的黑暗面，但在疫情的阴影之下却忍不住要为它高唱一曲赞歌。无疑，网络上存在许多可怕、黑暗，具有破坏性的东西。即使现在，我们也看到有人利用疫情进行新的网络攻击，以健康快讯和疫情地图为幌子传播恶意软件，进行网络欺诈。但在人类如此难以置信的脆弱时刻，我们却仍能一边禁足在家，一边利用网络学习、工作、锻炼、冥想、约会，感觉就像一个奇迹。互联网有时可能被滥用，但想想人类在数十年的时间就建立了一整个能同时能联结如此多人、拥有如此全面功能的系统，仍不禁觉得自豪。比起现代医药或公共卫生，互联网更点燃了我们对未来的希望，相信我们会创造更多伟大的事物，虽然现在我们还不知其貌不知其如何伟大，但它们会以想象不到的方式帮助我们渡过至暗时刻。
