Unit 3 The Internet
一、阅读理解（本大题共4小题，共8.0分）
A
All networks like 3G and 4G will be things of the past, because people already have access to 5G. So, what's so special about a 5G future First of all, its download speed can be as fast as 20GB/s, which is 100 to 200 times faster than that of 4G. But what's more impressive is 5G's low delay rate. Now, 4G takes an average of 200 milliseconds to send and receive information. But 5G will get it down to 1 millisecond.
5G is a great breakthrough(突破). It's going to change the way equipment connects to the Internet, and more importantly, to each other. And self-driving cars may be one of the biggest breakthroughs to come out of 5G. Human reaction(反应) time is 200 milliseconds, yet we still have accidents every day. The self-driving car under the 5G network could react and communicate its reaction to hundreds of cars around it, all within 1 millisecond. It'll play a great role in preventing car accidents and completely ending traffic jams.
5G can benefit us in many other ways. Operations could be performed by robots controlled by experts from the other side of the world. Therefore, more lives will be saved in time. Factories can be staffed by robots that can communicate their tasks to each other, and they can do more work over the 5G network. As a result, more labour forces will be freed.
However, 5G is not perfect. 5G uses the millimeter waves, while 4G uses the 15- to 40-centimeter-long waves. And shorter waves go fast but not very far. On the 4G network, the signal(信号) can go 10 kilometers. But the 5G signal can go at most 300 meters, and it can't even go through walls or rain. So, what does that mean Having such a short signal distance means we need to build a lot of signal towers in the future.
1. How does the author introduce 5G in paragraph 1
A. By giving examples of the uses of 5G.
B. By reviewing 5G s development from 4G.
C. By providing some basic information of 5G.
D. By making comparisons between 4G and 5G.
2. Why are self-driving cars mentioned in paragraph 2
A. To show the advantage of 5G.
B. To prove the importance of 5G.
C. To explain the role of self-driving cars.
D. To tell the progress of self-driving cars.
3. What does the underlined part "be staffed by robots" mean
A. Be built by robots. B. Have robots as workers.
C. Offer employees robots. D. Produce more robots.
4. What can we know about the 5G signal
A. It uses longer waves. B. It needs fewer signal towers.
C. It travels a shorter distance. D. It won t be affected by weather.
二、阅读七选五（本大题共5小题，共10.0分）
One of my earliest memories was watching my mom talk on our old phone. I was fascinated(被迷住的) to see that she could talk to someone who wasn't actually in the room with her. When she left the room, I slowly walked over to the phone and stared at it for a while. (1)

Remember that we are here to love each other, help each other and make this world a better place. (5) But when it can't, turn it off.
A. Then came computers and smartphones.
B. Take a walk on the beach with a friend.
C. Smartphones have both advantages and disadvantages.

But the 5G signal can go at most 300 meters, and it can't even go through walls or rain.（5G使用毫米波，而4G使用15—40厘米长的波。较短的波走得很快，但不会很远。在4G网络中，信号可以传播10公里。但5G信号最多可以传播300米，甚至无法穿透墙壁或雨。）可知，5G信号的传输距离比4G信号短。故选C。

3. 根据下文中的Few take the time to talk face to face. Instead of looking into the eyes of our loved ones, we stare at our screens. It seems as if the most connected generation are also the loneliest（很少有人会花时间面对面地交谈。我们盯着屏幕，而不是看着我们所爱的人的眼睛。似乎联系最紧密的一代也是最孤独的一代）可知，很少有人面对面交谈，我们只是盯着屏幕，似乎联系最多的一代也是最孤独的一代，因此G项（然而，让我们烦恼的是，如今我们很少彼此联系）符合语境。故选G。
4. 根据下文中的Have a long conversation with the phones off and the hearts on（关上电话，敞开心扉，进行一次长谈）可知，此处是放下手机进行面对面交流的另一种方式，所以B项（和朋友在海滩上散步）符合语境。故选B。

一、阅读理解（本大题共4小题，共8.0分）
A
All networks like 3G and 4G will be things of the past, because people already have access to 5G. So, what's so special about a 5G future First of all, its download speed can be as fast as 20GB/s, which is 100 to 200 times faster than that of 4G. But what's more impressive is 5G's low delay rate. Now, 4G takes an average of 200 milliseconds to send and receive information. But 5G will get it down to 1 millisecond.
5G is a great breakthrough(突破). It's going to change the way equipment connects to the Internet, and more importantly, to each other. And self-driving cars may be one of the biggest breakthroughs to come out of 5G. Human reaction(反应) time is 200 milliseconds, yet we still have accidents every day. The self-driving car under the 5G network could react and communicate its reaction to hundreds of cars around it, all within 1 millisecond. It'll play a great role in preventing car accidents and completely ending traffic jams.
5G can benefit us in many other ways. Operations could be performed by robots controlled by experts from the other side of the world. Therefore, more lives will be saved in time. Factories can be staffed by robots that can communicate their tasks to each other, and they can do more work over the 5G network. As a result, more labour forces will be freed.
However, 5G is not perfect. 5G uses the millimeter waves, while 4G uses the 15- to 40-centimeter-long waves. And shorter waves go fast but not very far. On the 4G network, the signal(信号) can go 10 kilometers. But the 5G signal can go at most 300 meters, and it can't even go through walls or rain. So, what does that mean Having such a short signal distance means we need to build a lot of signal towers in the future.
1. How does the author introduce 5G in paragraph 1
A. By giving examples of the uses of 5G.
B. By reviewing 5G s development from 4G.
C. By providing some basic information of 5G.
D. By making comparisons between 4G and 5G.
2. Why are self-driving cars mentioned in paragraph 2
A. To show the advantage of 5G.
B. To prove the importance of 5G.
C. To explain the role of self-driving cars.
D. To tell the progress of self-driving cars.
3. What does the underlined part "be staffed by robots" mean
A. Be built by robots. B. Have robots as workers.
C. Offer employees robots. D. Produce more robots.
4. What can we know about the 5G signal
A. It uses longer waves. B. It needs fewer signal towers.
C. It travels a shorter distance. D. It won t be affected by weather.

Remember that we are here to love each other, help each other and make this world a better place. (5) But when it can't, turn it off.

2. 根据第二段中的5G is a great breakthrough(突破). It's going to change the way equipment connects to the Internet, and more importantly, to each other. And self-driving cars may be one of the biggest breakthroughs to come out of 5G（5G是一个伟大的突破。它将改变设备连接互联网的方式，更重要的是，改变设备之间的连接方式。自动驾驶汽车可能是5G技术带来的最大突破之一）可知，第二段提到无人驾驶汽车是为了展示5G带来的益处。选A。
3. 根据第三段的内容，尤其是Factories..more labour forces will be freed（工厂里可以配备机器人，这些机器人可以相互传递任务，利用5G网络做更多工作，这样能解放更多的劳动力。）故B项（让机器人当工人。）与画线短语意思最接近。故选B。
4. 根据最后一段中的5G uses the millimeter waves, while 4G uses the 15-to 40-centimeter-long waves. And shorter waves go fast but not very far. On the 4G network, the signal(信号) can go 10 kilometers. But the 5G signal can go at most 300 meters, and it can't even go through walls or rain.（5G使用毫米波，而4G使用15—40厘米长的波。较短的波走得很快，但不会很远。在4G网络中，信号可以传播10公里。但5G信号最多可以传播300米，甚至无法穿透墙壁或雨。）可知，5G信号的传输距离比4G信号短。故选C。
5~9.【答案】F、A、G、B、D
【解析】1. 【文章大意】随着新科技的出现，人们只是盯着屏幕，很少有人面对面交谈，彼此之间很少联系。在文章中作者告诉我们当科技可以让世界变得更好的时候，就使用它，反之，就关掉它。

2. 根据上文中的Later, we had mobile phones that could be carried around the room（后来，我们有了可以在房间里随身携带的手机）和下文中的send an e-mail（用智能手机发送电子邮件）可知，后来，我们有了可以到处携带的移动手机，然后电脑和智能手机出现了。所以A项（然后是电脑和智能手机。）符合语境，起承上启下的作用。故选A。
3. 根据下文中的Few take the time to talk face to face. Instead of looking into the eyes of our loved ones, we stare at our screens. It seems as if the most connected generation are also the loneliest（很少有人会花时间面对面地交谈。我们盯着屏幕，而不是看着我们所爱的人的眼睛。似乎联系最紧密的一代也是最孤独的一代）可知，很少有人面对面交谈，我们只是盯着屏幕，似乎联系最多的一代也是最孤独的一代，因此G项（然而，让我们烦恼的是，如今我们很少彼此联系）符合语境。故选G。
4. 根据下文中的Have a long conversation with the phones off and the hearts on（关上电话，敞开心扉，进行一次长谈）可知，此处是放下手机进行面对面交流的另一种方式，所以B项（和朋友在海滩上散步）符合语境。故选B。
5. 根据上文中的Remember that we are here to love each other, help each other and make this world a better place（记住，我们在这里是为了互相爱，互相帮助，让这个世界变得更美好）和下文But when it can't, turn it off（但当它不能，关掉它）可知，记住我们要彼此相爱，互相帮助，让世界成为更美好的地方。D项（当科技可以帮助做这些事情的时候，就使用它）符合语境。故选D。
