Unit 4 Information Technology
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 20 GB/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.
A. Then came computers and smartphones.
B. Take a walk on the beach with a friend.
C. Smartphones have both advantages and disadvantages.
