【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 (遠程醫(yī)療) 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.less fast data download and upload speeds

B.more unstable connections

C.the much faster mobile Internet

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

A.the Internet of ThingsB.transportationC.mobile Internet

【3】The underlined word "react" in Paragraph 3 means __________in Chinese.

A.駕駛B.反應(yīng)C.思考

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

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

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

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

【5】The best title for this passage would be "__________".

A.Future TechnologyB.5G Network Is on the WayC.The Advantages of 5G

【答案】

【1】C

【2】A

【3】B

【4】B

【5】B

【解析】

文章主要是向人們介紹5G的到來，以及給人們的生活會帶來怎樣的變化以及5G的劣勢。

【1】細節(jié)理解題。根據(jù)文中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. 首先，5G承諾更快的數(shù)據(jù)下載和上傳速度，以及更穩(wěn)定的連接。這意味著您將能夠在幾秒鐘內(nèi)下載整個高清電影，并且在發(fā)送和接收數(shù)據(jù)之間僅經(jīng)歷短暫的延遲�？芍且驗�5G是更快的移動互聯(lián)網(wǎng)。故選C。

【2】細節(jié)理解題。根據(jù)文中Smart homes are part of it. For example, your toaster could automatically (自動地) start making breakfast after your alarm rings. 智能家庭是其中的一部分。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@里是說5G在物聯(lián)網(wǎng)方面的事情，故選A。

【3】詞義猜測題。根據(jù)文中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“對話”。5G將顯示汽車的……甚至比人類駕駛員更快�？芍@里的react指的是“反應(yīng)”而非速度快，故選B。

【4】細節(jié)理解題。根據(jù)文中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. 如果說過去幾年是5G技術(shù)的測試和發(fā)展，那么今年是時候展示一些真正的應(yīng)用了�？芍�A選項是錯誤的；根據(jù)文中This big change will not only make our mobile Internet faster. It will also change every industry like health care in telemedicine (遠程醫(yī)療) and self-driving cars. 這個巨大的變化不僅會使我們的移動互聯(lián)網(wǎng)更快。它還將改變每一個行業(yè)，如遠程醫(yī)療保健和自動駕駛汽車�？芍�B選項是有可能的，所以B選項是正確的；根據(jù)文中5G will show cars to react even faster than human drivers. 5G將顯示汽車的反應(yīng)甚至比人類駕駛員更快�？芍皇瞧嚫�，是反應(yīng)更快，所以C選項是錯誤的，故選B。

【5】最佳標題題。根據(jù)文章的理解可知，文章主要是講述5G網(wǎng)絡(luò)的到來，今年會有一些真正的應(yīng)用，并列介紹5G網(wǎng)絡(luò)給人們的生活帶來的變化，以及一些有待解決的弊端，所以B選項是比較符合的，故選B。

【題目】 If you go to a fast food restaurant, you will probably see a lot of teenagers. Today, many teenagers are overweight, and some of this is because of their bad eating habits(習(xí)慣). Most teenagers love food with a lot of fat, oil, salt, and sugar. People often call this kind of food “junk food".

But bad eating habits go beyond fast food. We find many teenagers eat unhealthily. Some don't have breakfast before they go to school. During the day, some don't have a proper meal for lunch. In a recent survey at one school, scientists found that over two-thirds of the students didn't follow a healthy diet（飲食）. They didn't like vegetables, and many of them didn't like to eat fruits. They enjoy eating food with a lot of salt, sugar, or fat. Parents today also worry about their children's diet. Some doctors give the following advice:

★ Teenagers shouldn't eat too much junk food.

★ Teenagers shouldn't eat food with too much salt. Salt can cause high blood pressure（高血壓）in the future.

★ Teenagers should eat food with less fat, oil, and sugar.

★ Teenagers need to eat some fruits and vegetables every day. Fruits and vegetables are rich in vitamins（維生素）and have little fat.

【題目】任務(wù)型閱讀

In our lives, we sometimes say or do something that may hurt others. Then we need to apologize(道歉). Making an apology helps to improve an injured friendship.

We are already familiar with some expressions for apologizing, such as “Excuse me” or “I'm sorry”. There are also other ways to apologize, such as “Pardon” and “I apologize”. When you have missed your friend's party, you might say, “I was really busy that day and just couldn't make it. I sincerely(真誠地) apologize.” When you get angry with someone and realize you are wrong, you may say, “I am sorry. I apologize for my poor attitude.”

When a person apologizes to you, it is necessary to reply politely, “It's all right，” or “Never mind.” If the situation is more serious and the person is really sincere, you might say, “I understand how you feel，” or “We all make mistakes.”

Sometimes people apologize not for having done something wrong, but for the inconvenience(不便)they have caused. On the building under repair you may see signs reading, “We are rebuilding our store to serve you better. Please pardon our dust.” In the supermarket you may hear a salesperson say, “I'm sorry it has been sold out today. Would you please come tomorrow？”

People sometimes are embarrassed to make an apology, because they do not want to lose face. Yet there are ways to make an “indirect apology”. Making an apology on the phone s or direct very personal way of apologizing, but it is sometimes the best choice. If one is not so familiar with the other and they might feel there is a chance of unpleasantness, some “distance” is often safer and understandable.

Learning how to apologize is important in our life. We don't lose face when we apologize. Instead, we'd lose face if we never say sorry for our mistakes.

【1】完成句子________________ helps to improve an injured friendship.

【2】完成句子When you ________________ with someone and realize you are wrong, you may say, “I am sorry. I apologize for my poor attitude.”
