【题目】 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 (应用) 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 (远程医疗) and self-driving cars. These cars can send signals to each other. They also "talk" to traffic lights and road sensors (传感器) . 5G will show cars to react even faster than human drivers.
5G also makes the Internet of Things (IoT物联网) possible. IoT is a large network that connects everything to the Internet. Smart homes are part of it. For example, your toaster could automatically (自动地) 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 (传输基地) 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.驾驶B.反应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】
文章主要是向人们介绍5G的到来，以及给人们的生活会带来怎样的变化以及5G的劣势。
【1】细节理解题。根据文中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承诺更快的数据下载和上传速度，以及更稳定的连接。这意味着您将能够在几秒钟内下载整个高清电影，并且在发送和接收数据之间仅经历短暂的延迟。可知是因为5G是更快的移动互联网。故选C。

【3】词义猜测题。根据文中These cars can send signals to each other. They also “talk” to traffic lights and road sensors (传感器) . 5G will show cars to react even faster than human drivers. 这些车可以互相发送信号。他们还与交通灯和道路传感器“对话”。5G将显示汽车的……甚至比人类驾驶员更快。可知这里的react指的是“反应”而非速度快，故选B。
【4】细节理解题。根据文中If the past few years were about testing and developing of 5G technology, it’s time to show some real applications (应用) this year. 如果说过去几年是5G技术的测试和发展，那么今年是时候展示一些真正的应用了。可知A选项是错误的；根据文中This big change will not only make our mobile Internet faster. It will also change every industry like health care in telemedicine (远程医疗) and self-driving cars. 这个巨大的变化不仅会使我们的移动互联网更快。它还将改变每一个行业，如远程医疗保健和自动驾驶汽车。可知B选项是有可能的，所以B选项是正确的；根据文中5G will show cars to react even faster than human drivers. 5G将显示汽车的反应甚至比人类驾驶员更快。可知不是汽车更快，是反应更快，所以C选项是错误的，故选B。
【5】最佳标题题。根据文章的理解可知，文章主要是讲述5G网络的到来，今年会有一些真正的应用，并列介绍5G网络给人们的生活带来的变化，以及一些有待解决的弊端，所以B选项是比较符合的，故选B。

【题目】 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(习惯). 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（饮食）. 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（高血压）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（维生素）and have little fat.

【题目】任务型阅读
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(真诚地) 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.”
