3G到底是什么意思?
G牌照,此舉標(biāo)志著我國(guó)正式進(jìn)入3G時(shí)代。那么3G能夠在全球范圍內(nèi)更好地實(shí)現(xiàn)無(wú)縫漫游,并處理圖像、音樂(lè)、視頻流等多種媒體形式,提供包括網(wǎng)頁(yè)瀏覽、電話會(huì)議、電子商務(wù)等多種信息服務(wù),同時(shí)也要考慮與已有第二代系統(tǒng)的良好兼容性。為了提供這種服務(wù),無(wú)線網(wǎng)絡(luò)必須能夠支持不同的數(shù)據(jù)傳輸速度,也就是說(shuō)在室內(nèi)、室外和行車的環(huán)境中能夠分別支持至少2Mbps(兆比特/每秒)、384kbps(千比特/每秒)以及144kbps的傳輸速度。(此數(shù)值根據(jù)網(wǎng)絡(luò)環(huán)境會(huì)發(fā)生變化)。 此次下發(fā)的三張牌照,中國(guó)移動(dòng)的TD-SCDMA,全稱為Time Division-Synchronous Code Division Multiple Access(時(shí)分同步的碼分多址技術(shù)); 中國(guó)電信的CDMA2000,全稱Code Division Multiple Access 2000含義為碼分多址系統(tǒng)標(biāo)準(zhǔn)2000;而中國(guó)聯(lián)通的WCDMA是Wideband Code Division Multiple Access的縮寫,意思是寬帶碼分多址。 3G只是一種標(biāo)準(zhǔn),符合這個(gè)標(biāo)準(zhǔn)的技術(shù)做出來(lái)的才是3G手機(jī),所以買手機(jī)的時(shí)候可別被人忽悠了哦。 滬江口語(yǔ)資料“絕密版” 免費(fèi)贈(zèng)送活動(dòng)進(jìn)行中

At the two sessions in 2019, the press center realized the full coverage of 5G signal for the first time, and the "minister channel" carried out the 5G+VR live broadcast for the first time. With the support of brand-new technology, it further enriched the reporting methods and means of financial media and injected new vitality and elements into the two sessions. 以上就是今天的學(xué)習(xí)內(nèi)容啦,大家要利用好考前剩余的時(shí)間認(rèn)真?zhèn)淇?。小編祝各位同學(xué)能順利通過(guò)六級(jí)考試~ ?

【雅思寫作】G類投訴信的常見(jiàn)思路(下)
收到,在信件結(jié)構(gòu)上和投訴質(zhì)量低劣類似: ? (一)表明投訴原因。 ? (二)陳述投訴內(nèi)容,如物品的特征,郵寄的時(shí)間等,并指出由此而產(chǎn)生的后果。 ? (三)提出整改建議或者希望得到對(duì)方的賠償或補(bǔ)償。 ? 讓我們結(jié)合真題來(lái)分析下: ? Your mother sent you a parcel. But two months later you still have not received it. Write a letter to the post office. In your letter, ? 1. tell them when and where the parcel was sent ? 2. describe the contents in the parcel ? 3. say what you would like them to do ? 這類題目的寫作思路首先是詳細(xì)描述該包裹寄出的時(shí)間和地點(diǎn),比如: ? The parcel is a cardboard box sent from Beijing on May 18th to my current address: 33 North Street, Toronto, Canada. ? 其次,需要說(shuō)一下包裹的內(nèi)容,并指出這些物品可能已經(jīng)由于時(shí)間太長(zhǎng)而損壞,比如: ? My mother enclosed some summer clothes and some Chinese specialties for me, including local dates. I doubt those dates must have been spoiled on the way for such a long time. ? 此外,若題目中未提及具體物品,我們除了說(shuō)包裹外,還可以說(shuō)是一封信或者是重要文件。郵寄外,我們還可以說(shuō)是快遞中物品未收到或者遺失,此物品是生日禮物或者公司重要檔案,對(duì)于收件方的意義或者價(jià)值巨大等來(lái)擴(kuò)充寫作思路。

【雅思寫作】G類投訴信的常見(jiàn)思路(上)
?投訴信一直是移民類小作文常考的話題,根據(jù)筆者多年的教學(xué),發(fā)現(xiàn)投訴信一般可以從以下四個(gè)思路去發(fā)展。 一、投訴理由1:服務(wù)不周 ? 投訴信中投訴服務(wù)是經(jīng)常會(huì)考到的話題,一般主要集中在對(duì)于飯店,賓館,餐廳,旅行社等服務(wù)性行業(yè)的投訴,此類書信一般在結(jié)構(gòu)上可分為以下幾個(gè)部分: ? (一) 自我介紹,表明投訴內(nèi)容以及與收信人的相關(guān)性。 ? (二) 陳述投訴內(nèi)容,如時(shí)間、地點(diǎn)、人物、事件等,并指出對(duì)方服務(wù)問(wèn)題所在以及由此而產(chǎn)生的對(duì)自己或者家人的影響。 ? (三) 提出整改建議或者希望得到對(duì)方的賠償或補(bǔ)償。 ? 讓我們結(jié)合真題來(lái)分析一下: ? You just returned from a tour. However, you were dissatisfied with the service you received from the travel agency. Write a letter to the manager of the agency. In your letter,? ? 1. give the details of your tour ? 2. explain why you were unhappy with the service ? 3. say what you want the company do for you ? 題目并無(wú)指明具體投訴內(nèi)容,因此考生選擇余地較大,一般來(lái)說(shuō),建議考生可以考慮旅行社安排的住所不好,比如房間臟等。具體寫法如下: ? The room was not cleaned on a daily basis and that my bed was made up only every three days.? ? 還可以說(shuō)房間沒(méi)有熱水,比如: ? The hot water was only supplied from 6:00 am to 10:00 pm, which means if I arrived back at the hotel late, it was impossible for me to take a shower with hot water. ? 此外,還可以圍繞吃飯問(wèn)題進(jìn)行投訴,如: ? The food in the restaurant was disappointing. Not only was it extremely overpriced, but the quality was very poor.? ? 上述所提到的關(guān)于服務(wù)質(zhì)量的投訴,大家不難發(fā)現(xiàn)里面說(shuō)的房間,熱水,吃飯問(wèn)題其實(shí)換一個(gè)服務(wù)性行業(yè)的考題我們也可以套用。因此我們要熟記這些基本的投訴點(diǎn)。 ? 二、投訴理由2:質(zhì)量低劣 ? 投訴信中反映產(chǎn)品質(zhì)量低劣是經(jīng)常會(huì)考到的話題,一般分為2種:一種是在題目中指明具體產(chǎn)品,如服裝、CD-player等;另一種是不具體指明買的產(chǎn)品是什么,讓考生自己去虛構(gòu)一樣物品,此類書信在結(jié)構(gòu)上一般由三部分組成: ? (一)表明投訴原因以及與收信人的相關(guān)性。 ? (二)陳述投訴內(nèi)容,如購(gòu)買的時(shí)間、地點(diǎn)、人物等,并指出產(chǎn)品具體問(wèn)題所在以及由此而產(chǎn)生的后果。 ? (三)希望得到對(duì)方的賠償或補(bǔ)償。 ? 讓我們結(jié)合真題來(lái)分析一下: ? You have recently made a purchase from a department store in another town but found some problems with it after you returned home. Write a letter to the manager. In your letter, ? 1. say what product you have bought ? 2. explain the problems ? 3. say what you would like them to do ? 題目并無(wú)指明具體產(chǎn)品,因此考生選擇余地較大,一般來(lái)說(shuō),考生可以考慮服裝。關(guān)于服裝的投訴點(diǎn),一般可以說(shuō)新買的衣服褪色問(wèn)題嚴(yán)重,品質(zhì)有問(wèn)題。具體寫法如下: ? The color of the sweater faded heavily and even dyed other clothes. ? 還可以說(shuō)標(biāo)簽和配件丟失,比如: ? I put on the shirt that day when I returned home and found the buttons on the left sleeve were missing. Also, I couldn’t find the label of the shirt, so I was unable to know the proper way of washing or hanging it. ? 此外,圍繞服裝的投訴點(diǎn)還可以是材質(zhì)和描述不符,尺寸大小不合身等,如: ? The garment was stretched out of shape and therefore no longer fits. ? 考生可以從中選擇一兩項(xiàng)進(jìn)行描述,還可以從對(duì)方店員服務(wù)態(tài)度方面入手,如: ? I phoned your store last Wednesday and spoke to the store manager, a Mr. Wang, who was rather unprofessional and inconsiderate on the phone and informed me that I was unable to get a replacement shirt as it was not their fault. ? 上述所四提到的投訴產(chǎn)品的思路,可以作為考生在準(zhǔn)備投訴信件時(shí)的基本切入點(diǎn)。上面所提到的關(guān)于服務(wù)態(tài)度的投訴幾乎可以“百搭”各類質(zhì)量投訴話題的信件。因此建議考生不妨從記憶“經(jīng)典”套路為本,根據(jù)具體考試題目再做調(diào)整,起到以不變應(yīng)萬(wàn)變的效果。 (未完待續(xù))

走近4G:手機(jī)上網(wǎng)迎來(lái)百兆時(shí)代(視頻)
Fourth generation wireless services are on the way. Licences to operate the 4G wireless system have still not been issued in China, but the government says that could happen by the end of the year. How is it coming along? A [w]fantastic[/w] mobile experience. This is one of China Mobile’s 4G service centers in Zhengzhou, the provincial capital of Henan. Every day customers in the city can come to try out the 4G service in advance. The fourth-generation wireless service is designed to deliver speed... four to ten times faster than today's 3G system, which is currently the most widespread, high-speed wireless service. Shen Zhiwei, engineer of China Mobile, said, “The max download speed at peak rate can reach to 112 mega bits per second. And the average speed can also reach to 100 mega bits per second as well. It means if we download a movie of 1 gigabyte, it will take only 1 minute to complete in a 4G [w]connection[/w]. That’s ten time faster than 3G.” China's biggest telecom carrier, China Mobile, is promoting a homegrown 4G standard and hopes to start commercial rollout as soon as possible. The core technologies have been developed and the company has been ramping up its base station installations. Li Xiaobang, , engineer of China Mobile, said, “The 4G wireless network shares the same base stations with the 3G network. So the first step for us is to examine all the base stations and report the data to the [w]technological[/w] centers. And then we place the wires. It will take a while, but we hope we can finish the work as soon as we can so that people can use the new service once the 4G license is issued. ” There are 1.2 billion mobile phones in China, more than any other country in the world. The government says it will press ahead with building [w]infrastructure[/w] and hopes to issue 4G licenses by the end of this year. That’s good news for people looking forward to a brand-new mobile life. 聲明:音視頻均來(lái)自互聯(lián)網(wǎng)鏈接,僅供學(xué)習(xí)使用。本網(wǎng)站自身不存儲(chǔ)、控制、修改被鏈接的內(nèi)容。"滬江英語(yǔ)"高度重視知識(shí)產(chǎn)權(quán)保護(hù)。當(dāng)如發(fā)現(xiàn)本網(wǎng)站發(fā)布的信息包含有侵犯其著作權(quán)的鏈接內(nèi)容時(shí),請(qǐng)聯(lián)系我們,我們將依法采取措施移除相關(guān)內(nèi)容或屏蔽相關(guān)鏈接。
