BDS appears later 2 America's GPS, Russia'sGLONASS and EU's Galileo, but it can match them. As one of the fourth 3 (globe) navigation satellitesystems, BDS involves efforts of over 400 agencies and 300,000 research personnel and technicians.Originally 4 (plan) in the 1980s, the network represents a milestone in China's space effort. BDS iscomparable to GPS in terms of the 5 (accurate) of positioning. It also offers short messagecommunication and thus can provide emergency communications in areas 6 conventionalcommunication signals are poor in an effort 7 (improve) the quality of their positioning services, Appleand Samsung phones, among others, are already using BDS's signals, and so8 (be) every Chinese brand.The construction of complete BDS is a huge technical achievement for China and can 9 (easy) pay10in the near future. Meanwhile, BDS's great contribution to promoting the world's economic and social development as well as the peaceful use of space has attracted the world's attention.【2】閱讀選擇In the distant past, our ancestors relied on stars to guide them on a clear night. Today, we havenavigational(導(dǎo)航的)systems to help us find our way, the latest of which is the Beidou Navigation Satellite System (BDS).The BDS is entirely built by Chinese engineers. With the launch of the last satellite from the Xichang Satellite Launch Center on June 23, the global network of 59 satellites has been completed. On July 31,優(yōu)點(diǎn)英語(yǔ)Beidou started providing services covering our whole planet.Its difficult to imagine the grea t influence those satellites have on our daily lives. When you unlockone of Hellobikes bicycles, you are using the BDS. “The intelligent lock on each bike receives Beidousatellite signals and sends positioning information to the data center which will help collect big data on thebikes and predict users riding needs in advance according to the data,” Chu Yiqun, a manager of Hellobikementioned. Users can also find shared bikes more accurately(精確地) thanks to Beidous global positioning accuracy of 2.34 meters.Beidou adopts a unique two-way communication system, including its ability to receive messages sentby people from areas with poor communication signals. Obviously this function isnt designed for users to chat online. Instead, it plays a role when disasters occur and communications are blocked.After the Wenchuan Earthquake in 2008, all ground-based communication facilities were interrupted.Though the first generation of Beidou could only send 120 characters in a single message at that time,communication between affected areas and rescue(救援) centers was successful. Now, Beidous messagingability has been increased to 1, 200 Chinese characters in a single message. It is widely used in disaster alarms, automatic identification and information release.As Sun Jiadong, former chief designer of the BDS said: “ The application(應(yīng)用) of Beidou is only limited by imagination.”11What can we learn about the BDS from the passage?AIt was developed by Chinese and American engineers.BIt works better on clear nights.CIts last satellite was launched on July 31.DIts able to provide global coverage for navigation.12Why does the author mention Hellobike in Paragraph 3?ATo stress the excellent positioning ability of the BDS.優(yōu)點(diǎn)英語(yǔ)BTo show how the BDS makes peoples daily lives easier.CTo present the advantages and disadvantages of the BDS.DTo explain how the BDS works.13What is Beidous two-way communication system designed for?ATo help people when communication signals are poor.BTo make users daily communication more fun.CTo allow users to chat online more freely.DTo collect data from users for the data center.14What does the underlined sentence in the last paragraph mean?ABeidou may be more helpful than we know.BBeidou inspires users imagination.CBeidou needs to be further improved.DBeidou is limited in application.參考答案1have been sent2than3global4planned優(yōu)點(diǎn)英語(yǔ)5accuracy6where7to improve8is9easily10off【分析】本文是一篇新聞報(bào)道。文章主要介紹了中國(guó)自主研發(fā)的北斗導(dǎo)航衛(wèi)星系統(tǒng)。1考查現(xiàn)在完成時(shí)的被動(dòng)語(yǔ)態(tài)。句意：直到2020 年 6 月 23 日，已經(jīng)發(fā)射了 55 顆北斗衛(wèi)星，意味著中國(guó)自主研發(fā)的北斗導(dǎo)航衛(wèi)星系統(tǒng)已經(jīng)完成。本句描述過(guò)去發(fā)生的事情對(duì)現(xiàn)在的影響用現(xiàn)在完成時(shí)， 55 BeiDou satellites 與 send 是被動(dòng)關(guān)系，用被動(dòng)語(yǔ)態(tài)，故填 have been sent。2考查介詞。句意：北斗導(dǎo)航衛(wèi)星系統(tǒng)比美國(guó)的 “ 全球定位系統(tǒng) ”、俄羅斯的 “GLONASS”和歐洲的“ 伽 利略”出現(xiàn)的晚一些。根據(jù)形容詞比較級(jí) later 可知，此處應(yīng)填“比”，故填 than。.3考查形容詞。句意：作為全球第四大導(dǎo)航衛(wèi)星系統(tǒng)，北斗導(dǎo)航衛(wèi)星系統(tǒng)中包含超過(guò) 400 家機(jī)構(gòu)、300000個(gè)研究者和技術(shù)人員的努力。根據(jù)句子結(jié)構(gòu)可知，此處應(yīng)填形容詞，修飾名詞短語(yǔ) navigation satellite systems，故填 global。4考查過(guò)去分詞。句意：這個(gè)網(wǎng)絡(luò)的計(jì)劃起始于 20 世紀(jì) 80 年代，它代表著中國(guó)空間站努力的里程碑。根據(jù)句子結(jié)構(gòu)可知，空格處是句子的狀語(yǔ)，the network 與 plan 是動(dòng)賓關(guān)系，表示被動(dòng)，所以用過(guò)去 分詞作狀語(yǔ)。故填 planned。優(yōu)點(diǎn)英語(yǔ)5考查名詞。句意：在定位的精確性方面，北斗導(dǎo)航衛(wèi)星系統(tǒng)可以與全球定位系統(tǒng)相比。作in terms of 的賓語(yǔ)用名詞，根據(jù)句意故填“精確”，不可數(shù)名詞，故填 accuracy。6考查定語(yǔ)從句。句意：它也能提供短信通訊。這樣就可以為通訊信號(hào)差的地方提供緊急通訊。根據(jù)句意及句子結(jié)構(gòu)可知，此處引導(dǎo)定語(yǔ)從句，先行詞是 areas，在從句中作地點(diǎn)狀語(yǔ)，故填 where。7考查非謂語(yǔ)動(dòng)詞。句意：為了改善定位服務(wù)的質(zhì)量，蘋(píng)果手機(jī)、三星手機(jī)準(zhǔn)備使用北斗導(dǎo)航衛(wèi)星系 統(tǒng)的信號(hào)。in an effort to do sth.意為“努力做某事，為了做某事”，故填 to improve。8考查時(shí)態(tài)和主謂一致。句意：每個(gè)中國(guó)的品牌也是如此。陳述的是客觀事實(shí)，用一般現(xiàn)在時(shí)，此處使用的是倒裝句式“so+be+主語(yǔ)”，表示：也是，主語(yǔ) every Chinese brand 是單數(shù)名詞，故填 is。.9考查副詞。句意：建設(shè)完北斗導(dǎo)航衛(wèi)星系統(tǒng)對(duì)中國(guó)來(lái)說(shuō)，是技術(shù)上的巨大成就，它在不遠(yuǎn)的將來(lái)可 以容易地實(shí)現(xiàn)。修飾謂語(yǔ)動(dòng)詞用副詞，故填 easily。 ，10考查介詞。句意：建設(shè)完北斗導(dǎo)航衛(wèi)星系統(tǒng)對(duì)中國(guó)來(lái)說(shuō)，是技術(shù)上的巨大成就，它在不遠(yuǎn)的將來(lái)可 以容易地實(shí)現(xiàn)。pay off 是一個(gè)固定短語(yǔ)，意為：付清，取得成功。故填 off。11D12B13A優(yōu)點(diǎn)英語(yǔ)14A【分析】本文是說(shuō)明文。文章介紹了北斗導(dǎo)航衛(wèi)星系統(tǒng)在我們生活中的應(yīng)用。11細(xì)節(jié)理解題。文章第二段中提到“the global network of 59 satellites has been completed. On July 31,Beidou started providing services covering our whole planet. ”北斗系統(tǒng)的全球 59 顆衛(wèi)星網(wǎng)絡(luò)已經(jīng)完成，北斗系統(tǒng)開(kāi)始提供覆蓋全球的服務(wù)。由此可知，北斗系統(tǒng)能夠提供全球范圍的導(dǎo)航服務(wù)。故選D。12推理判斷題。文章第三段中提到“Its difficult to imagine the great influence those satellites have onour daily lives.（很難想象這些衛(wèi)星對(duì)我們?nèi)粘Ｉ畹木薮笥绊懀?；下文舉出 Hellobike 的例子，“Whenyou unlock one of Hellobikes bicycles, you are u sing the BDS. （當(dāng)你解鎖一輛 Hellobike 自行車(chē)時(shí)，你就使用了北斗系統(tǒng)）”和“Users can also find shared bikes more accurately(精確地) thanks to Beidousglobal positioning accuracy of 2.34 meters.（由于北斗全球衛(wèi)星定位精度可達(dá)到 2.34 米，用戶還可以更準(zhǔn)確地找到共享自行車(chē)）”。由此可知，作者是以 Hellobike 為例說(shuō)明北斗系統(tǒng)對(duì)人們?nèi)粘Ｉ畹挠?響，以及如何讓人們的日常生活更輕松。故選 B。13細(xì)節(jié)理解題。根據(jù)第四段中“Beidou adopts a unique two-way communication system, including its abilityto receive messages sent by people from areas with poor communication signals.（北斗系統(tǒng)采用獨(dú)特的雙向通信系統(tǒng)，能夠接收來(lái)自通信信號(hào)較差地區(qū)的人們發(fā)送的信息）”和“it plays a role when disastersoccur and communications are blocked. （當(dāng)災(zāi)難發(fā)生、通訊中斷時(shí)，它就會(huì)發(fā)揮作用）”可知，北斗 雙向通信系統(tǒng)是為了在通訊信號(hào)不好或者信號(hào)中斷時(shí)幫助人們。故選 A。14詞句猜測(cè)題。最后一段中前首席設(shè)計(jì)師孫家棟說(shuō) “The application of Beidou is only limited byimagination.（北斗的應(yīng)用只受到想象力的限制）”，意即北斗系統(tǒng)還有更多的其他的應(yīng)用，是人們還 沒(méi)有想象到的。北斗系統(tǒng)對(duì)我們的幫助可能比我們能想到的更多。故選 A。
