Each mobile network generation is faster and more powerful than the one before it. 1G let us talk to each other. 2G let us send messages. 3G gave us data and the Internet. 4G made all of these things faster. What’s special about 5G?
5G has a very short delay between sending and receiving information. Now, 4G takes about 100 to 200 milliseconds (毫秒) to send and receive data. But 5G will get it down to 1 millisecond or less. This big change will deeply change our lives. Read on to find out how.
5G entertainment (娱乐)
5G networks are about 100 times faster than 4G. This means you can download a movie in seconds using 5G. The short delay of 5G will make the games feel even more real.
5G transportation (交通)
5G will also bring us safer self-driving cars. These cars can send signals to each other. They also talk to traffic lights and road sensors.
5G smart homes
5G also makes the Internet of things possible. Internet of things is a large network that connects everything to the Internet. Smart phones are part of it. For example, your toaster can automatically (自动地) start making breakfast after your alarm rings.

UK’s red phone boxes to be saved from closure
The UK’s first phone boxes started coming up in 1921, with the special red design appearing five years later. At the most of time in 1992, BT（英国电信集团）operated 92,000 of them.
But as mobiles became part of everyday life, many phone boxes were removed or re-used for services like community libraries and coffee shops. There are now just 21,000 left.
OFCOM（英国通信管理局）wants to protect 5,000 phone boxes, specially in poor mobile coverage areas（覆盖地区）. It says they still offer a valuable emergency function, with 150,000 999 calls（999紧急求救电话）made from phone boxes last year.

Technology has influenced the way we communicate. Instead of sending letters or cards, we’re writing e-mails. Besides, we can send greeting cards to our friends on the Internet. No postage (邮费) is needed.
Sending a note to a friend can be done in a few seconds on the Internet. We may even see a friend if he is there and talk to many people at a time.
Mobile phones become very important in our lives, too. We can use them to give calls no matter where we are. And sending text massages is another effective (有效的) way to communicate.
However, everything has two sides. Great technology has made us feel farther and farther away from the real society. And it’s difficult to tell if the net friends we are talking to are really kind to us. Even worse, many young people have forgotten how to spell and write complete sentences because of the Internet and smart-phones (智能手机).
Some people think that we might miss something more important in our life when only paying attention to technology. It’s time for us to wake up.
1. Is postage needed when we send greeting cards to our friends on the Internet?2. How soon can sending a note be done on the Internet?
3. How can we use mobile phones to communicate?
4. Do you think technology is good for us? Why or why not?
Email helps workers to communicate at any time, from any place. Email is an important tool, but it can also lead to a waste of time. How can workers make sure that email is a tool and not a time-waster? Here are some simple tips to follow. They can help you use email more efficiently (高效地) at work.
First of all, turn off the sound in your computer that tells you that you have a new email message. That “You’ve got mail!” sound is like a telephone or a doorbell. It interrupts your work. When you hear it, you will want to check your messages. And it will take you at least a few minutes to get back to work after that. Can you imagine how much time you waste because of that little sound?
Second, limit how often you check your email. Try checking it only three times a day, for example, at 9:00, 12:00 and 16:00. Also, limit the time you spend reading and answering email each time. Fifteen minutes is usually long enough.
Third, use a separate email account for work and personal life. Do not give your work address to friends or family, and do not give your personal address to people at work. If you are working on several projects at one time, use a separate email account for each one. So you can focus on the most important project.
Fourth, you won’t have to read all the email messages every time you open your email. You can look quickly at the subject lines and then decide which messages to answer right away. You can read the others later.
Finally, do not always use “reply to all” to answer email. Only send the message to people who need to read your answer. That way, you won’t fill your workmates’ inboxes with messages that they don’t need. And they won’t waste time reading them.
If you follow these simple steps, you will be a more efficient worker. Best of all, you will be able to leave the office earlier.

【推荐2】Some etiquette (礼仪) in modern life
Do you often use a mobile phone? Do you take the underground to school every day? These items make our modern life easier. But do you know how we should behave properly while using them? The following suggestions might be helpful.
For mobile phone users
◆Keep your voice down when you make a phone call in public. Shouting on the phone may make others feel uncomfortable. And you’d better not use it during an appointment (约会).
◆Stop sending messages or playing games with your mobile phone at a dinner or a party. It’s a good time to communicate with your family and friends.
◆Don’t make or answer a call while driving. It is not only very dangerous for both you and your passengers but also against the law.
For underground passengers
◆You are supposed to wait in line while buying tickets and getting on the underground.
◆You can’t eat, drink or smoke on the underground train. The smell and noise may bring others trouble. It’s our duty to keep the train clean and tidy. Besides, smoking is bad for health.
◆You can’t take pets onto the train. As we all know, animals may spread diseases (传播疾病) and make the train dirty.
◆You’d better not lie on the underground seats even if the train isn’t crowded. Offering your seat to someone who needs it is regarded as good manners.

【推荐1】What do you think the schools of the future will be like? Smart campuses（校园）have come into use all over the world.
The University of British Columbia has created Canada’s first 5G-powered smart campus. Its high-tech helps students learn more and faster, as well as makes it easier for teachers to give their classes.
At Staffordshire University in the UK, many students enjoy talking to Beacon and asking it questions. Beacon is an AI chat robot that was developed by the university. It is like a personal assistant（助手）for students at the school. They can ask it questions, such as whether or not one of their classes is canceled.
Some universities in the world use the voice-activated（声控的）smart assistant—Alexa. It can help teachers run their classes better. For example, Alexa can remember the teacher’s classroom preferences, such as how bright the lights should be, and change them accordingly.
Universities often have their own transportation, roads, shops and banks. They are good places to test smart technology because they have control over all of their buildings. “Universities are like a living lab,” said a designer who is working on a smart campus development for the University of Glasgow.

【推荐2】How has technology made your life easier? When you go to a shopping mall, you can enjoy free WiFi there. When you want to take a taxi, you can order one with your phone. In fact, all of these things can be seen as the first step of a smart city.
The idea of a smart city was first suggested by a tech company, IBM in 2010. A smart city is a city that uses digital (电子的) technology, like 5G networks, to save money, resources (资源) and make our lives more convenient.
Cities like Boston and Amsterdam are already using smart technology to improve public services. In Boston, smart trash bins (垃圾箱) can be seen everywhere. When the trash bins are almost full, they can ring loudly to remind cleaners to clean them.
Smart cities will allow us to save resources. Computers and 5G networks help check water, gas pipes. In this way, they could easily remind workers to repair them when there is a leak (泄露) in.
Of course, it will take time to build the smart cities of the future. But since we’ve already seen successful examples, it won’t be long until more cities join in. By 2050, about 60% of people will live in smart cities.
1. What can you do if you want to order taxis according to the passage?We can order taxis

Technology can make our life
Do you know what 5G is? It is the fifth generation of mobile network technology（第五代移动网络技术）. Each mobile network generation is faster and more powerful than the one before it. 1G let us talk to each other. 2G allowed us to send messages. 3G brought us the mobile Internet. And 4G made all of these things work faster. What’s special about 5G then?
5G shortens the time between sending and receiving information. Now, 4G takes about 100 to 200 milliseconds（毫秒）to send and receive information. But 5G will get it down to 1 millisecond or less-this is almost real-time. The big change will not only provide us with better services, but also change our lives in different fields.
5G + entertainment（娱乐）
5G networks are about 100 times faster than 4G. This means you can download（下载）a movie in seconds. Also, VR games will become much more popular because 5G will make the games more real.
5G + transportation（交通）
5G will bring us much safer self-driving cars. These cars can communicate with each other and the traffic lights. With the help of 5G technology, cars can do things even faster than human drivers.
5G + smart homes
With 5G, we can have smart homes which allow us to live in a comfortable way. For example, to make your bread maker make breakfast by itself in the morning, you just need to do a simple thing before going to bed-setting an alarm. The smart watering machine can water your plants if it feels the air becoming dry.
