三、阅读单选
（一）
I am the engine that keeps you working well all day long, and I am here to share some of the secrets you might not know.
I have 1000 billion nerve cells(神经细胞). So you need to consider before you blame(责备) me for not being so quick enough, or forgetting your friend’s birthday. It is not really my fault. Information travels through me too fast and sometimes l can’t keep all of it.
The Internet is making me weak. A study found that you have been relying(依赖) more on the Internet. That means I am going to forget more over time. Scientists have been worried that our ability to think is losing.
In general, I am about ten percent larger in men than women. It doesn’t make men smarter. It just lets me control their different bodies. Actually, it’s more common for women to get angry, but men can’t concentrate on a thing well. They usually have language difficulties.
Your mobile phone scares me. A new research showed that more than one hour of mobile phone use can get me in trouble. Mobile phone radiation(辐射) might cause me to be in a worse situation, like sleep problems.
Some parts of me never sleep. It’s important for you to get a good night’s sleep. Sleep helps to improve memories. It may also help me process them. In fact, when you are asleep, some parts of me are still working hard on my duty.
Besides, laughter is really the best medicine for me. When I hear laughter, I produce something useful that makes me work better. So remember to laugh more for my better situation.

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” of your mobile network. But these symbols will become things of the past after 5G networks fully arrive.
On March 30th, 2019, Shanghai vice-mayor（副市长）Wu Qing made the first 5G video call on a Huawei Mate X smart phone, CGTN reported. 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. When the car “sees” an obstacle(障碍物), it sends the information to a data center and receives instructions. However, it takes time to send and receive information. With this kind of lag, the cars might crash because they don’t receive instructions in time. With 5G, this lag will be great lowered, making the cars safer, according to CNN.
5G could also be used to power the Internet of Things（IOT). This refers to a large online network that connects all things and people. Fast Internet speeds will be the key to develop this technology. The IOT could be used in a lot of ways. For example, with IOT, your refrigerator could automatically place an order online for eggs when it finds that there are no eggs left inside.
China is working on test runs of 5G systems in 17 cities across the country. And it is true that China is becoming the world’s largest 5G market, with 450 million users by 2025, China Daily reported.
41．What is the main difference between the 5G and 4G
A．The price B．The speed C．The color D．The users
42．The writer uses self-driving cars as an example to ________.
A．explain how 5G’s fast speed can be helpful
B．warn about dangers of self-driving cars
C．explain how self-driving cars work
D．tell us the reason why Shanghai people like to use self-driving by 5G
43．What does the underlined word “lag” mean in Chinese
A．延迟 B．暂停 C．耗电 D．迷路
44．Which of the following is TRUE according to the passage
A．Shanghai is the only city in China to start testing 5G networks.
B．IOT is an online store where you can buy anything.
C．17 cities in China have started testing 5G.
D．There are 450 million 5G users in China.
