Unit 3 The Internet（本卷满分100分） 一、阅读理解（每小题2分，共16分）AAll 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 accidentsB. slow down 5G’s developmentC. run without being connected to the InternetD. have a much faster reaction speed than humans3. 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.BThe Consumer Technology Association, formerly called The International Consumer Electronics Show, or CES, believes about 170,000 people will attend the show. About one-third of them are reported to come from countries besides the United States.More than 4,000 businesses will show products used through the Internet such as gaming, self-driving cars, artificial intelligence(人工智能) and robotics. One of the biggest stars at CES this year is the voice-controlled digital(数字的) assistant. While the technology is not new, many companies will show off the latest digital assistants.Equipment controlled by digital assistants, especially those turned on by voice, were already big sellers in 2017. This year, Google, Amazon and Apple are expected to release even more products to keep up with the rising demand.Digital assistants are powered by artificial intelligence and machine learning technology. They are designed to learn users’ preferences over time and then “think” and act on their own. Some of the biggest developments in technology have come in the area of home automation(自动化). Amazon Echo, Google Home, Apple’s Home Pod and Microsoft’s Cortana are a few examples of voice-controlled equipment. All include smart speakers that “talk” to users inside the house and can perform operations.Experts with the Consumer Technology Association say sales of smart speakers are expected to nearly double in 2019.The Internet-linked products can play music or find information when asked questions. They can also control equipment such as lighting, cameras, televisions and temperature controllers. Among new “smart” home products to be released at the CES are voice-controlled washing machines, refrigerators, showers and toilets. There is also much new physical fitness and health-related equipment on show. Some are designed to help people create the best personal fitness plans to reach their goals. Wearable health equipment is used to study and measure body conditions, while others help recognize signs of disease.5. What will be shown at CES?A. Books about robots.    B. International fashion.C. Schools’teaching art.    D. Equipment related with the Internet.6. Why are Google, Amazon and Apple expected to develop more intelligent products?A. To create music.     B. To treat all kinds of diseases.C. To meet the increasing needs.   D. To make experiments in space.7. How do users communicate with the equipment of home automation?A. By fax.       B. By voice.C. By email.      D. By body language.8. In which part of a newspaper may this text appear?A. Art.   B. Health.   C. Education.   D. Technology. 二、七选五（每小题2分，共10分）The Internet has opened up a whole new online world for us to meet, chat and go where we’ve never been before.But just as in face to face communication, there are some rules of behavior that should be followed when online.   9   Imagine how you’d feel if you were in the other person’s shoes.For anything you’re about to send: ask yourself, “Would I say this to the person’s face?” if the answer is no, rewrite and reread.   10  If someone in the chat room is rude to you, your instinct(本能) is to fire back in the same manner. But try not to do so.   11   If it was caused by a disagreement with another member, try to fix the situation by politely discussing it. Remember to respect the beliefs and opinions of others in the chat room.  12   Offer advice when asked by newcomers, as they may not be sure what to do or how to communicate. When someone makes a mistake, whether it’s a stupid question or an unnecessarily long answer, be kind about it. If it’s a small mistake, you may not need to say anything. Even if you feel strongly about it, think twice before saying anything. Having good manners yourself doesn’t give you license to correct everyone else.   13   At the same time, if you find you are wrong, be sure to correct yourself and apologize to those that you have offended.It is not polite to ask others personal questions such as their age, sex and marital status. Unless you know the person very well, and you are both comfortable with sharing personal information, don’t ask such questions.A. It’s natural that there are some people who speak rudely or make mistakes online.B. Repeat the process till you feel sure that you’d feel comfortable saying the words to the person’s face.C. Everyone was new to the network once.D. The basic rule is simple: treat others in the same way you would want to be treated.E. When you send short messages to a person online, you must say something beautiful to hear.F. You should either ignore the person, or use your chat software to block their messages.G. If you do decide to tell someone about a mistake, point it out politely. 三、完形填空（每小题1.5分，共30分）Many people tend to bring electronic products when travelling, including me.
