【題目】 Have you heard of 5G? It is the fifth generation of mobile network technology. If the past few years were about testing and developing of 5G technology, it’s time to show some real applications ( 應(yīng)用) this year. What changes will 5G bring to us?

First, 5G promises much faster data download and upload speeds, and more stable connections. This means that you will be able to download an entire HD movie in seconds and only experience a short delay between sending and receiving data. Also, VR games will become more popular with 5G. The short delay of 5G will make the games more real.

This big change will not only make our mobile Internet faster. It will also change every industry like health care in telemedicine and self-driving cars. These cars can send signals to each other. They also “talk” to traffic lights and road sensors (傳感器). 5G will show cars to react even faster than human drivers.

5G also makes the Internet of Things (IoT 物聯(lián)網(wǎng)) possible. IoT is a large network that connects everything to the Internet. Smart homes are part of it. For example, your toaster could automatically ( 自 動 地 ) start making breakfast after your alarm rings.

Though 5G makes our lives more convenient, it will not be perfect. For one thing, 5G will not “travel” far. On 4G networks, we can be 10 kilometers away from the nearest transmission base (傳輸基地) and barely lost signal. But 5G will only cover about 300 meters, meaning that we will need more transmitters so that we can get signals. And in order to use 5G, we will have to buy new products specifically designed for 5G that are presently expensive.

【1】You will be able to download an entire HD movie in seconds because 5G promises .

A.slower mobile InternetB.more unstable connections

C.much faster data download and upload speedsD.a long delay between sending and receiving data

【2】The examples of the toaster is used to explain the usage of 5G in the area of .

A.communicationB.transportationC.mobile InternetD.the Internet of Things

【3】The underlined word “react” in Paragraph 3 means in Chinese.

A.駕駛B.反應(yīng)C.思考D.行動

【4】Which of the following is TRUE according to the passage?

A.5G technology is in the period of testing this year.

B.Special designed phones for 5G are not expensive at present.

C.Self-driving cars are faster than human drivers with the help of 5G.

D.With the help of 5G, patients can see the doctor through the Internet.

【5】The best title for this passage would be “ ”.

A.Future TechnologyB.The Fastest Generation

C.The advantages of 5GD.5G Network is on the Way

【答案】

【1】C

【2】D

【3】B

【4】D

【5】D

【解析】

本文是一篇說明文，主要說明和介紹了5G作為第五代移動網(wǎng)絡(luò)技術(shù)，給我們的生活各個領(lǐng)域帶來的變化。

【1】細(xì)節(jié)理解題。根據(jù)“First, 5G promises much faster data download and upload speeds, and more stable connections.” 首先，5G保證了更快的數(shù)據(jù)下載和上傳速度，以及更穩(wěn)定的連接�？芍绻隳茉趲酌腌妰�(nèi)下載一部完整的高清數(shù)字電影，是因為5G保證了更快的數(shù)據(jù)下載和上傳的速度。故選C。

【2】細(xì)節(jié)理解題。根據(jù)“5G also makes the Internet of Things (IoT 物聯(lián)網(wǎng)) possible. …For example, your toaster could automatically start making breakfast after your alarm rings.”5G還使物聯(lián)網(wǎng) 成為可能。……例如，你的烤面包機可以在你的鬧鐘響后自動開始做早餐�？芍每久姘鼨C的例子說明了5G技術(shù)在物聯(lián)網(wǎng)領(lǐng)域里的使用。故選D。

【3】詞句猜測題。根據(jù)“These cars can send signals to each other. They also “talk” to traffic lights and road sensors (傳感器). 5G will show cars to react even faster than human drivers.”這些車可以互相發(fā)送信號。他們還與交通燈和道路傳感器“交談”。5G將顯示汽車反應(yīng)比人類司機更快。可知本句說明通過5G技術(shù)的使用，汽車和汽車之間，汽車和交通燈及道路傳感器相互連接，從而使得汽車比人類司機駕駛反應(yīng)更快。故推測react表示“反應(yīng)”的含義。故選B。

【4】推理判斷題。根據(jù)“If the past few years were about testing and developing of 5G technology, it’s time to show some real applications ( 應(yīng)用) this year.” 如果過去幾年是關(guān)于5G技術(shù)的測試和開發(fā)，那么今年是展示一些實際應(yīng)用的時候了，可知5G技術(shù)已經(jīng)通過測試，進(jìn)入實際運用了。故A項錯誤。根據(jù)“And in order to use 5G, we will have to buy new products specifically designed for 5G that are presently expensive.”為了使用5G，我們將不得不購買專門為5G設(shè)計的新產(chǎn)品，這些產(chǎn)品目前價格昂貴�？芍厥庠O(shè)計的5G手機目前不貴是不正確的，故B項錯誤。根據(jù)“These cars can send signals to each other. They also “talk” to traffic lights and road sensors (傳感器). 5G will show cars to react even faster than human drivers.” 這些車可以互相發(fā)送信號。他們還與交通燈和道路傳感器“交談”。5G將顯得汽車反應(yīng)比人類司機更快。此處只是提及5G技術(shù)的汽車反應(yīng)更快，而不是速度更快。故C項錯誤。根據(jù)“It will also change every industry like health care in telemedicine and self-driving cars.”它也將改變每一個行業(yè)，如醫(yī)療保健和自動駕駛汽車。推斷可知在5G的幫助下，病人能夠通過網(wǎng)絡(luò)看病。故D項正確。故選D。

【5】最佳題目題。Future Technology未來技術(shù)；The Fastest Generation最快速的一代；The advantages of 5G 5G的優(yōu)點；5G Network is on the Way 5G網(wǎng)絡(luò)正在路上。根據(jù)本文文意，主要介紹了5G技術(shù)將會在我們的生活各個領(lǐng)域帶來的變化。 故“5G網(wǎng)絡(luò)正在路上”符合題意。故選D。

Criticism (批評) is everywhere in life, so you need to learn how to deal with it.

Ask yourself how the criticism will influence you. Will you lose something important because you are criticized? Surely not! So, don’t worry about it. Instead, remember that some criticism actually helps you improve.

You cannot stop what people say. What you can do, however, is to change the way you deal with criticism. You have the right to decide what to do with the criticism you receive.

Don’t be afraid to accept criticism. No one likes to be told that he is wrong. Yet, every person has ever been criticized for something. Realize that it’s normal. You may have received some strong criticism, but it doesn’t mean that you are foolish, or that you don’t have the ability to do something properly. Try not to think of it in that way and don’t take it seriously. If you can learn to be optimistic, you will reduce some stress and nervousness about what people think.

Consider where the criticism comes from. It may help you find out what causes the criticism. Is the person just trying to offer useful criticism? This type of criticism is known as valid criticism. On the other hand, there are persons that offer their advice just to be useless. This is known as invalid criticism because it is often not of any use at all.

Do your best. And if someone doesn’t like what you’ve done, so what? It’s either valid criticism or invalid criticism. But you have the power to decide how you will allow it to influence you.

Title: How to deal with criticism
