一、语法填空

1.distance

2.Inspired

3.accessible

4.rudeness

二、完形填空

1.Doaccepted接受;noticed注意;heard听说；听见;met遇见。根

据第一句可知很多人只是通过电话了解你，你们也许从来都没有见

过面，只是通过电话交流。故选D。

2.Bothus因此；yet然而；then然后；indeed实际上，确实。虽

然你们之间的距离很远，但是他们只要通过你的声音，就可以了解

你。上下文之间是转折关系，所以使用副词yet。故选B。

3.Aotelephone电话；voice声音；connection连接；impression

印象。根据故事第一段及第二段中onlybyphone可知是作者在谈

电话的作用，人们可以通过电话了解你。这说明了电话功能的强大,

故选Ao

4.Dodirect直接的juseful有用的;easy容易的;accurate准确的。

上文提到电话功能强大，but说明上下文之间是转折关系，电话虽然

很强大，但是也并不是很准确。故选D。

5.Aoinperson本人，亲自；bymyself独自地，单独地；inpublic

公开地，当众;onpurpose故意地。与空前的faceless形成呼应，

Rani是我的代理人，但是我们从来没有碰过面。故选A。

6.Aoannoyed生气的,烦恼的；interested感兴趣的;discouraged

灰心的，泄气的；confused困惑的。由空前的coldvoice可知Rani

在电话里的声音很冷漠，这让我很不高兴，甚至想过要另外找一个

代理人。说明我对她的声音很反感。故选A。

7.Doarrange安排；postpone推迟；confirm确认；book预订。因为家

中的紧急事情我要立刻预订回家的航班。动词book与flight相搭配。

故选Do

8.Bo考查动词辨析。expecting期待，预料；seeing看见；testing

检测；avoiding避免。看到我那么着急，Rani非常同情我。动词see

与上下文搭配一致。故选B。

9.Boshy害羞的;comforting安慰的；familiar熟悉的；forced被迫

的。她看到我很着急，笑着安慰我。故选B。

10.Cohopefully充满希望地；disappointedly失望地；gratefully

感激地;regretfully遗憾地。Rani如此迅速地帮我把机票打印出来，

而且一直面带微笑，这让我心存感激。故选C。

11.Docareful细心的；serious严肃的，认真的；nervous紧张

的;pleasant令人愉快的。现实生活中的Rani富有同情心，待人热

情大方，是一个可以愉快相处的人。所以当我转身时，看见的是与电

话中完全不一样的Rani。故选D。

12.Doamused愉快的；worried担心的；helpless无助的；

speechless无语的。我之前认为她很冷漠，甚至有了要另找代理的

想法，而现实生活中的她是如此的体贴大方，这让我真是无言以对。

故选Do

13.Bocalm平静的；nice和蔼的，友善的；proud自豪的；clever

聪明的。前句提到WhyhadIthoughtshewascold?可知之前我认

为Rani很冷漠，但却没有想到实际生活中的Rani是如此和蔼。故选

Bo

14.Coforgiveness谅解;eagerness渴望;friendliness友

好;skillfulness熟练。从上文可知R
