2、works like a two-way radio when communicating with cell towers，the GPS capability simply extends the radio signal reach to space satellites.Phones equipped with full-featured capabilities work off of Java-based radio signals and have database access to their providers system for other data like mapp

3、ing and voices.Location tracking，and giving directions to and from destinations are some of the more common uses for this technology.GPS navigational systems are supported by a network of 27 satellites.These satellites orbit the Earth in cyclic patterns 24 hours a day.At any given time，a minimum of

4、four satellites signals is accessible to any one point on Earth.Whenever a receiver device is activated，radio waves with coded messages are sent out to it.This is how satellites know to start tracking the device.A receivers exact location is determined through a process called trilateration(三边测量法) w

5、here three satellites work together to narrow down possible location points.A fourth satellite is needed if the receiver isnt on the ground and altitude is wanted as well.Distance calculations are made based on how long it takes the radio signals to travel back and forth between receiver and satelli

6、tes.The mapping capabilities are displayed on the phones screen via the cell providers database.As a GPS device needs to do all kinds of calculations on different data from satellites and providers database，it consumes time.So it can take quite a few seconds for a regular GPS to work out a plan.An a

7、ssisted GPS can help solve the problem.It is an improved technology that uses a cell networks Assistance Server which is connected to a reference network such as the Internet.Through the use of cell towers，a phone relays satellite signal information to the servers.These servers are able to process i

8、ncoming data at much higher rates than GPS receivers，so information is processed quicker，and is typically more accurate.1What does the underlined word “their” refer to?ASatellites. BPhonesCSignals. DCapabilities答案B解析代词指代题。这个句子涉及到长难句的分析，equipped with.作为定语修饰phones，and连接两个并列的谓语，一个是work off，一个是have，所以an

9、d 后面的句子其实是 phones have database access to their providers system.，即their指代“手机的”。2Which of the following is TRUE according to the information in the text?APhone GPS is a new technology unrelated to a cell phones original functions.BA mobile phone works as a signal receiver and processor in phone GPS

10、system.CEach mobile phone is assigned four fixed satellites for their coded messages.DMapping capabilities and distance calculations are affected by the speed of radio signals.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。3What do we know about the Assistance Server in the Assisted GPS?AIt can

11、 speed up calculating process of a regular GPS receiver.BIt is part of the cell network directly connected to the Internet and the phone.CIt has a better functioning performance in processing received radio signals.DIt helps the Assisted GPS to receive different data more accurately in bad condition

12、s.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：1What does the underlined word “this/it/them/which.” refer to?2The underlined part “it/that/they/which.”in Par

14、句子为“Phones equipped with full-featured capabilities work off of Java-based radio signals and have database access to their providers.”可知整个句子的主语是Phones，故their就相当于Phones。A(2018河南新乡二模)Throughout the past few years，I have tried to give myself to others.I have bounced around to find where I truly fit in.
