四、阅读理解
36．阅读理解
All
networks like 3G and 4G will be things of the past, because 5G will be
reachable in the near future. 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
that of 4G. But what's more impressive is 5G's low delay rate. Now, 4G takes an
average of 200 milliseconds(毫秒) to send and receive information.
But 5G will get it down to 1 millisecond.
5G is a
great breakthrough. 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 time is 200
milliseconds, yet we still have accidents every day. The self-driving car under
a 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 ending traffic jams completely.
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 efficiently
over a 5G network. Imagine a group of drones(无人机) flying over a field of crops, using sensors(传感器) on the ground to sort, pick, feed, and water plants all on their
own. Then farmers won't have to work so hard anymore.
However,
5G is not perfect. One major disadvantage has to do with why it's so fast. 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 4G networks, the signal 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 transmitters(信号发射塔) in the future.
（1）How does the author show us 5G's advantages in Paragraph 1
A．By giving examples of the uses of 5G.
B．By making comparisons between 4G and 5G.
C．By explaining the scientific principles of 5G.
D．By analyzing 5G's development from 4G.
（2）According to the author, the self-driving cars will ________.
A．cause more car accidents
B．slow down 5G's development
C．run without being connected to the Internet
D．have a much faster reaction speed than humans
（3）What does the underlined part "be staffed by robots" in Paragraph 3 mean
A．Be built by robots. B．Have robots as workers.
C．Offer employees home robots. D．Produce more medical robots.
（4）What does the last paragraph mainly talk about
A．The main weakness of 5G networks.
B．How to make 4G networks more perfect.
C．The types of long waves and short waves.
D．How to improve the signal of mobile phones.
【答案】（1）B
（2）D
（3）B
（4）A
【解析】【分析】本文是一篇说明文，介绍了3G和4G等所有网络都将成为过去，因为5G将在不久的将来实现。那么，5G有何特别之处呢？5G给我们工作、生活带来改变，但是5G也有它的缺点。
（1）考查推理判断。第一段说明所有网络，比如3G和4G都将是过去的事情，因为5G将在不远的将来实现。那么，5G有什么特别？首先，其下载速度可以高达20GB/秒，是4G的100至200倍。但更令人印象深刻的是5G的低延迟率。现在，4G发送和接收信息平均需要200毫秒，但5G却将把它降低到1毫秒。可以看出说明5G的优点是通过把5G和4G进行对比，所以论证方式是对比，故选B。
（2）考查细节理解。根据第二段中的 “Human reaction time is 200 milliseconds, yet we still have accidents every day. The self-driving car under a 5G network could react and communicate its reaction to hundreds of cars around it, all within 1 millisecond.” 可知人类反应时间是200毫秒，但我们每天仍有交通事故。5G网络下的自动驾驶汽车可以在1毫秒内对周围数百辆汽车做出反应。所以自动驾驶汽车比人类有更快的反应速度。故选D。
（3）考查词义猜测。根据第三段中的 “Operations could be performed by robots controlled by experts from the other side of the world.”可知操作可以由来自世界另一端的专家控制的机器人执行。这句话在画线短语所在句子之前，因此画线句句意：工厂可以配备可以相互传达任务的机器人，并且可以通过5G网络高效地完成更多工作。故选B。
（4）考查主旨大意。根据最后一段中的 “However, 5G is not perfect. One major disadvantage has to do with why it's so fast.” 可知5G并不完美。一个主要缺点与为什么它如此之快有关。这句是这一段的主题句，所以这一段介绍的是5G的缺点。故选A。
【点评】本题考点涉及细节理解，词义猜测，推理判断和主旨大意四个题型的考查，是一篇科技类阅读，要求考生在捕捉细节信息的基础上，进一步根据上下文的逻辑关系，进行分析，推理，概括和归纳，从而选出正确答案。
37．阅读理解
As
Internet users become more dependent on the Internet to store information, are
people remembering less If you know your computer will save information, why
store it in your own personal memory, your brain Experts are wondering if the
Internet is changing what we remember and how.
In a
recent study, Professor Betsy Sparrow conducted some experiments. She and her
research team wanted to know if the Internet is changing memory. In the first
experiment, they gave people 40 unimportant facts to type into a computer. The
first group of people understood that the computer would save the information.
The second group understood that the computer would not save it. Later, the
second group remembered the information better. People in the first group knew
they could find the information again, so they did not try to remember it.
In
another experiment, the researchers gave people facts to remember, and told
them where to find the information on the Internet. The information was in a
specific computer folder(文件夹). Surprisingly, people later
remember the folder location(位置) better than the facts.
When people use the Internet, they do not remember the information. Rather,
they remember how to find it. This is called "transactive memory(交互记忆)".
According
to Sparrow, we are not becoming people with poor memories as a result of the
Internet. Instead, computer users are developing stronger transactive memories;
that is, people are learning how to organize huge quantities of information so
that they are able to access it at a later date. This doesn't mean we are
becoming either more or less intelligent, but there is no doubt that the way we
use memory is changing.
（1）The passage begins with two questions to ________.
A．introduce the main topic B．show the author's attitude
C．describe how to use the Internet D．explain how to store information
（2）What can we learn about the first experiment
A．Sparrow's team typed the information into a computer.
B．The two groups remembered the information equally well.
C．The first group did not try to remember the information.
D．The second group did not understand the information.
（3）In transactive memory, people ________.
A．keep the information in mind
B．change the quantity of information
C．organize information like a computer
D．remember how to find the information
（4）What is the effect of the Internet according to Sparrow's research
A．We are using memory differently.
B．We are becoming more intelligent.
C．We have poorer memories than before.
D．We need a better way to access information.
【答案】（1）A
（2）C
（3）D
（4）A
【解析】【分析】本文是一篇议论文，介绍了互联网给人类的记忆带来的影响。互联网使用者越来越依赖互联网来储存信息，这样做是否会丧失记忆事物的能力呢？专家怀疑互联网可能正在改变人们的记忆内容和方式。
（1）考查推理判断。根据第一段中的 “Experts are wondering if the Internet is changing what we remember and how.” 专家们想知道，互联网是否正在改变我们的记忆，以及如何改变我们的记忆。这是本文的中心话题。因此推断，作者使用两个问句是为了引出要讨论的话题。故选A。
（2）考查细节理解。根据第二段 “People in the first group knew they could find the information again, so they did not try to remember it.” 可知第一组没有记信息。故选C。
（3）考查细节理解。根据倒数第二段 中的“Rather, they remember how to find it. This is called “transactive memory”. 可知，交互记忆引导人们记住怎样找到信息。故选D。
（4）考查细节理解。根据最后一段中的“ but there is no doubt that the way we use memory is changing ”可知，互联网对人们的记忆产生的影响是它改变了我们使用记忆力的方式。故选A。
【点评】本题考点涉及细节理解和推理判断两个题型的考查，是一篇社会类阅读，考生需要准确捕捉细节信息，并根据上下文进行逻辑推理，从而选出正确答案。
