二、阅读理解
A
If you look at the top of your phone, you’ll usually see a little symbol that says 3G or 4G. The “G” stands for the “generation(代)” of your mobile network. But the symbols will become things of the past after 5G networks fully arrive.
On March 30, Shanghai Vice-mayor(副市长) Wu Qing made the first 5G video call on a HUAWEI Mate X Smartphone. Shanghai has also become the first city in China to start testing 5G networks.
About 100 times faster than 4G networks, 5G will let people download and upload data faster than ever before. But 5G won’t just bring faster mobile Internet. People can use it for many other things as well.
For example, 5G will help to make self-driving cars safer. Today’s self-driving test cars have one problem-lag(延迟). When the car “sees” an obstacle(障碍物), it sends this information to a data center and receives instructions. However, it will be some time before it sends and receives this information. With this kind of lag, the cars might crash because they don’t receive instructions in time. With 5G, this lag will be greatly lowered, making the cars safer.
5G could also be used to power the Internet of things(IoT), that is a large online network that connects all things and people. Fast Internet speeds will be the key to developing this technology. The IoT could be used in a lot of ways. For example, with IoT, your refrigerator could automatically(自动地) place an order online for eggs when it finds that there are no eggs left inside.
17.Which city was 5G tested in for the first time in China
A.Beijing. B.Shanghai. C.Shenzhen. D.Qingdao.
18.What can we infer according to the passage
A.5G is widely used in China now.
B.5G networks will make our life more convenient.
C.There are no symbols at the top of our phones.
D.5G networks won’t help to make self-driving cars safer.
19.The writer used self-driving cars as an example to ________.
A.explain how 5G’s fast speed can be helpful
B.warn about the possible dangers of self-driving cars
C.explain how self-driving cars work
D.let people make sure that self-driving cars will be used at once
20.What is IoT according to the passage
A.A robot that can do housework.
B.An online store where you can buy anything.
C.A large online network that connects things and people.
D.Instruction of things.
21.Which sentence is right according to the passage
A.5G will help us buy eggs quickly.
B.Robots can help us buy eggs online.
C.With IoT, our refrigerator can order eggs online for us.
D.Our refrigerator can make eggs for us.
【答案】17.B 18.B 19.A 20.C 21.C
【导语】本文主要讲述了未来5G在各行各业的运用。
17.细节理解题。根据“Shanghai has also become the first city in China to start testing 5G networks.”可知,上海成为中国第一个开始测试5G网络的城市,故选B。
18.推理判断题。根据“About 100 times faster than 4G networks, 5G will let people download and upload data faster than ever before”及“People can use it for many other things as well”可知,5G能让网络比4G快100倍,人们在许多其他的地方也使用5G,说明5G让人们的生活更便利,故选B。
19.推理判断题。根据“People can use it for many other things as well.”和第三段内容可知,举这个例子是为了解释5G的高速是如何有帮助的,故选A。
20.细节理解题。根据“5G could also be used to power the Internet of things(IoT), that is a large online network that connects all things and people”可知,IoT指的是一个连接所有事物和人的大型在线网络,故选C。
21.细节理解题。根据“For example, with IoT, your refrigerator could automatically(自动地) place an order online for eggs when it finds that there are no eggs left inside.”可知,当你的冰箱发现里面没有鸡蛋时,它可以自动在网上订购鸡蛋,故选C。
B
On March 30th, 2019, Shanghai vice-mayor(副市长) Wu Qing made the first 5G video call on a Huawei Mate X smartphone. Shanghai has also become the first city in China to start testing 5G networks.
Now, 4G takes about 100 to 200 milliseconds to send and receive data(数据). But 5G will get it down to 1 millisecond or less. This big change will not only make our mobile Internet faster, but also deeply change our lives. For example, 5G will help to make self-driving cars safer. Today’s self-driving test cars have one problem — lag. When the car “sees” an obstacle(障碍物), it sends this information to a data center and receives instructions(指示). However, it takes time to send and receive this information. With this kind of lag, the cars might crash(撞击) because they don’t receive instructions in time. With 5G, this lag will be greatly lowered, making the cars safer.
5G could also be used to power the Internet of Things IOT(物联网). This refers to a large online network that connects(连接) all things and people. Fast Internet speeds will be the key to developing this technology. For example, with IOT under 5G, your refrigerator(冰箱) could place an order online for eggs by itself when it finds that there are no eggs left inside.
All in all, 5G will shape every type of technology that it touches. And you won’t have to wait too long for that to happen.

It can connect everyone and everything together. 5G networks will cover many cities in China soon. 5G means super-fast data speed. One can download a two-hour movie for fewer than 10 seconds, and it is making our lives more and more convenient.
5G will make self-driving cars possible. For safety, self-driving cars need super-fast data transmission (传输) to communicate with their nearby environment. 5G is just what makes self-driving cars achieve this. Even airplanes will become “smart” in the near future. Passengers will be able to use 5G networks in the air to connect to the Internet and can order for food and drinks.
5G will be a big help for students who take online classes. Many people live in poor areas in the world where there are no schools. But with 5G, this will change. Students all over the world will be able to see places like the Great Wall without leaving their rooms.
It will be also easier for doctors to treat patients remotely by 5G. It means caring for patients from far away.
The facts listed above are only a part of what 5G will make possible and popular. Just as in the early days of the Internet in the 1990s, few could see how it could change our life and the world. The same will surely be true of 5G. With 5G, many things do not seem like dreams any more. Now let’s get ready to say goodbye to 4G and welcome the coming of 5G.
27.How long may it take to download a two-hour movie with 5G
A.15 seconds. B.8 seconds. C.10 minutes. D.2 hours.
28.The underlined word “remotely” means “________” in Chinese.
A.快速地 B.高效地 C.远程地 D.科学地
29.5G will make the following things more and more popular EXCEPT ________.
A.self-driving cars B.“smart” airplanes
C.online classes D.hospitals without doctors
30.From the last paragraph, we can know that ________.
A.4G is no more used in our daily life now
B.the writer is worried about the coming of 5G
C.with 5G, some of our dreams will come true for sure one day
D.in the 1990s, all the people believed that the Internet would change our life
【答案】27.B 28.C 29.D 30.C
【导语】本文主要介绍了5G给我们带来的好处。
27.细节理解题。根据“One can download a two-hour movie for fewer than 10 seconds”可知可以在不到10秒的时间内下载一部两小时的电影。故选B。
28.词义猜测题。根据“It means caring for patients from far away”可知这意味着从远方照顾病人,故此处划线部分意为“远程地”。故选C。
29.细节理解题。根据“5G will make self-driving cars possible”、“Even airplanes will become ‘smart’ in the near future”以及“5G will be a big help for students who take online classes”可知5G将使自动驾驶汽车成为可能,在不久的将来,甚至飞机都将变得“智能”,5G将对上网课的学生有很大帮助。没有提到“没有医生的医院”。故选D。
30.细节理解题。根据“With 5G, many things do not seem like dreams any more”可知有了5G,很多事情都不再是梦想,即我们的梦想有一天会实现。故选C。
三、阅读还原

About 100 times faster than 4G networks, 5G will let people download and upload data faster than ever before. But 5G won’t just bring faster mobile Internet. People can use it for many other things as well.
For example, 5G will help to make self-driving cars safer. Today’s self-driving test cars have one problem-lag(延迟). When the car “sees” an obstacle(障碍物), it sends this information to a data center and receives instructions. However, it will be some time before it sends and receives this information. With this kind of lag, the cars might crash because they don’t receive instructions in time. With 5G, this lag will be greatly lowered, making the cars safer.
5G could also be used to power the Internet of things(IoT), that is a large online network that connects all things and people. Fast Internet speeds will be the key to developing this technology. The IoT could be used in a lot of ways. For example, with IoT, your refrigerator could automatically(自动地) place an order online for eggs when it finds that there are no eggs left inside.

B
On March 30th, 2019, Shanghai vice-mayor(副市长) Wu Qing made the first 5G video call on a Huawei Mate X smartphone. Shanghai has also become the first city in China to start testing 5G networks.
Now, 4G takes about 100 to 200 milliseconds to send and receive data(数据). But 5G will get it down to 1 millisecond or less. This big change will not only make our mobile Internet faster, but also deeply change our lives. For example, 5G will help to make self-driving cars safer. Today’s self-driving test cars have one problem — lag. When the car “sees” an obstacle(障碍物), it sends this information to a data center and receives instructions(指示). However, it takes time to send and receive this information. With this kind of lag, the cars might crash(撞击) because they don’t receive instructions in time. With 5G, this lag will be greatly lowered, making the cars safer.
5G could also be used to power the Internet of Things IOT(物联网). This refers to a large online network that connects(连接) all things and people. Fast Internet speeds will be the key to developing this technology. For example, with IOT under 5G, your refrigerator(冰箱) could place an order online for eggs by itself when it finds that there are no eggs left inside.
All in all, 5G will shape every type of technology that it touches. And you won’t have to wait too long for that to happen.

Whether from news reports or social media articles, you may know that 5G is coming.
5G is the 5th generation network. It is a new network after 1G, 2G, 3G and 4G. It can connect everyone and everything together. 5G networks will cover many cities in China soon. 5G means super-fast data speed. One can download a two-hour movie for fewer than 10 seconds, and it is making our lives more and more convenient.
5G will make self-driving cars possible. For safety, self-driving cars need super-fast data transmission (传输) to communicate with their nearby environment. 5G is just what makes self-driving cars achieve this. Even airplanes will become “smart” in the near future. Passengers will be able to use 5G networks in the air to connect to the Internet and can order for food and drinks.
5G will be a big help for students who take online classes. Many people live in poor areas in the world where there are no schools. But with 5G, this will change. Students all over the world will be able to see places like the Great Wall without leaving their rooms.
It will be also easier for doctors to treat patients remotely by 5G. It means caring for patients from far away.
The facts listed above are only a part of what 5G will make possible and popular. Just as in the early days of the Internet in the 1990s, few could see how it could change our life and the world. The same will surely be true of 5G. With 5G, many things do not seem like dreams any more. Now let’s get ready to say goodbye to 4G and welcome the coming of 5G.
