3、d voices.Location tracking，and giving directions to and from destinations are some of the more mon 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 four sat

4、ellites 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(三邊測量法) where thr

5、ee 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 satellites.The

6、 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 assiste

9、并列的謂語，一個是work off，一個是have，所以and 后面的句子其實是 phones have database access to their providers system.，即their指代“手機的”。,答案,解析,2.Which of the following is TRUE according to the information in the text?

10、ignal receiver and processor in phone GPS system. C.Each mobile phone is assigned four fixed satellites for their coded messages. D.Mapping capabilities and distance calculations are affected by the speed of radio signals.,答案,解析,解析推理判斷題。根據(jù)最后一段最后兩句可知，手機在GPS系統(tǒng)中的作用為信號的接收者和加工者。故選B。,3.What do we know abo

11、ut the Assistance Server in the Assisted GPS? A.It can speed up calculating process of a regular GPS receiver. B.It is part of the cell network directly connected to the Internet and the phone. C.It has a better functioning performance in processing received radio signals. D.It helps the Assisted GP

12、S to receive different data more accurately in bad conditions.,答案,解析,解析推理判斷題。根據(jù)最后一段前三句可知，GPS設備需要對來自衛(wèi)星和供應商數(shù)據(jù)庫的數(shù)據(jù)進行各種計算，它需要耗費時間，而輔助服務器幫助解決了這個問題，因此可以說它在處理接收到的信號這一功能上表現(xiàn)更好。,名師點津,一、題型解讀 代詞指代題常出現(xiàn)在人物或事物變換多，動作轉換頻繁的語境中，考生應根據(jù)語境判斷人稱代詞、不定代詞和指示代詞。有時也會考查定語從句中關系代詞的指代內容。設問形式常有： 1.What does the underlined word “this/

13、it/them/which.” refer to? 2.The underlined part “it/that/they/which.”in Paragraph.refers to .,二、解題技巧“就近原則”判指代 第一步：明確代詞所指代內容的位置 代詞永遠出現(xiàn)在原詞之后，故代詞所指代的內容在這一句的前面一句中，或者前幾句中。 第二步：熟悉代詞的含義 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等關系代詞指代其所修飾的先行詞，非限制性定語從句中which可指代前面整句話的內容。,第三

14、步：替換核實再比較 1.用所找的指代內容替換畫線代詞，核實句意是否合理，前后內容是否一致。 2.比較所指代部分與選項，確定意思最接近的選項。 例如：【感悟體會】中1題，畫線單詞所在的句子為“Phones equipped with full-featured capabilities work off of Java-based radio signals and have database access to their providers.”可知整個句子的主語是Phones，故their就相當于Phones。,隨堂限時練,A (2018河南新鄉(xiāng)二模) Throughout the past
