九、词句猜测——代词指代题

1．Whatdoestheunderlinedword“their”referto?

A．Satellites’.B．Phones’．

C．Signals’.D．Capabilities’．

答案　B

解析　代词指代题。

这个句子涉及到长难句的分析，equippedwith...作为定语修饰phones，and连接两个并列的谓语，一个是workoff，一个是have，所以and后面的句子其实是phoneshavedatabaseaccesstotheirproviders’system...，即their指代“手机的”。

2．WhichofthefollowingisTRUEaccordingtotheinformationinthetext?

A．PhoneGPSisanewtechnologyunrelatedtoacellphone’soriginalfunctions.

B．AmobilephoneworksasasignalreceiverandprocessorinphoneGPSsystem.

C．Eachmobilephoneisassignedfourfixedsatellitesfortheircodedmessages.

D．Mappingcapabilitiesanddistancecalculationsareaffectedbythespeedofradiosignals.

答案　B

解析　推理判断题。

根据最后一段最后两句可知，手机在GPS系统中的作用为信号的接收者和加工者。

故选B。

3．WhatdoweknowabouttheAssistanceServerintheAssistedGPS?

A．ItcanspeedupcalculatingprocessofaregularGPSreceiver.

B．ItispartofthecellnetworkdirectlyconnectedtotheInternetandthephone.

C．Ithasabetterfunctioningperformanceinprocessingreceivedradiosignals.

D．IthelpstheAssistedGPStoreceivedifferentdatamoreaccuratelyinbadconditions.

答案　C

解析　推理判断题。

根据最后一段前三句可知，GPS设备需要对来自卫星和供应商数据库的数据进行各种计算，它需要耗费时间，而辅助服务器帮助解决了这个问题，因此可以说它在处理接收到的信号这一功能上表现更好。

一、题型解读

代词指代题常出现在人物或事物变换多，动作转换频繁的语境中，考生应根据语境判断人称代词、不定代词和指示代词。

有时也会考查定语从句中关系代词的指代内容。

设问形式常有：

1．Whatdoestheunderlinedword“this/it/them/which...”referto?

2．Theunderlinedpart“it/that/they/which...”inParagraph...refersto.

二、解题技巧——“就近原则”判指代

第一步：

明确代词所指代内容的位置

代词永远出现在原词之后，故代词所指代的内容在这一句的前面一句中，或者前几句中。

第二步：

熟悉代词的含义

1．it/this/that可指代一件事。

2．it/he/them/they/one/those指上文提到的人或物。

3．which/that/who等关系代词指代其所修饰的先行词，非限制性定语从句中which可指代前面整句话的内容。

第三步：

替换核实再比较

1．用所找的指代内容替换画线代词，核实句意是否合理，前后内容是否一致。

2．比较所指代部分与选项，确定意思最接近的选项。

例如：

【感悟体会】中1题，画线单词所在的句子为“Phonesequippedwithfull-featuredcapabilitiesworkoffofJava-basedradiosignalsandhavedatabaseaccesstotheirproviders’．..”可知整个句子的主语是Phones，故their就相当于Phones’。
