Slowly but surely, we're moving closer and closer to 5G world. From smart-home security to self-driving cars, all the internet-connected devices in our life will be able to talk to each other at lightning-fast speeds with reduced delay. Objectively speaking, the fastest 4G download speeds in the US top out at an average of 19. 42 Mbps. But by comparison 5G promises gigabit (千兆)speeds.
“5G is one of those heralds (使者),along with artificial intelligence , of this coming data age.” said Steve Koenig, senior director of market research for the Consumer Technology Association. “The self-driving vehicle is a great emblem of this data age,and that is to say,it is a sign of time, because with one single task, driving, you have massive amounts of data coming from the vehicle itself, and a variety of sensors are collecting a lot of information to model its environment as it moves. It's pulling in data from other vehicles about road conditions down the lane. It could be weather information, and also connected infrastructure (基础设施)construction. There is lots of data behind that task, which is why we need the high speed.
And virtual reality glasses and headsets haven't yet broken the mainstream, but tech companies are joyfully betting that these devices will eventually replace our smart phones. With 5G, that could actually happen. This is notable because companies such as Apple are reportedly developing AR glasses to assist— or even replace — smart phones.
Ericsson stated at February's Mobile World Congress how smart glasses could become faster and lighter with a 5G connection, because instead of being weighed down with components, the glasses could rely on hardware for processing power.
But don't get too excited. There is still a lot of work to be done in the meantime, including various trials to make sure the radios play nicely with hardware and infrastructure construction so 5G isn't concentrated only in big cities.
1.What is the first paragraph mainly about?
A.A right security of 5G. B.The super speed of 5G.
C.A potential dream of 5G. D.The present world of 5G.
2.What do some tech companies expect of virtual reality glasses?
A.They will be heavier than present ones.
B.They will process power on their own.
C.They will serve people instead of smart phones.
D.They will bring a big fortune to tech companies.
3.What will the author tell us in the next paragraph?
A.How to fully expand 5G coverage.
B.How to effectively reduce 5G trials.
C.How to nicely operate 5G hardware.
D.How to widely construct 5G big cities.

Judy Wright and her husband decided to move closer to their son, Chris, who lived in Georgia. About a month after the move, Judy fell ill, suffering from her ongoing battle against Parkinson’s disease.
Judy’s condition worsened rapidly and she required medical care at home. The family hired a nursing aid who canceled at the last minute. Instead, a woman named TunDe Hector showed up in her place.
One day, TunDe shared a story with Judy and her family. She remembered a particularly difficult day in 2014, when a stranger helped her with a kind gesture. She had run out of gas, and with only $5 in her pocket, was walking to a gas station, gas can in hand. A man saw her walking and turned his car around. He paid for her gas and gave her all the cash left in his wallet. Upon hearing the story, Judy’s son, Chris, took off his hat and said, “That was me!” He was the stranger who had helped TunDe on that difficult day.
During the care of Judy, the Wright family learned about TunDe’s family and her own dream. The nursing aid, TunDe hoped that one day she could become an OB-GYN nurse. Her tuition was past due and she had a family to care for, but she was determined to achieve that goal for herself and her family.
Judy died on July 9, 2017. Instead of flowers, her family asked mourners to donate to TunDe’s education, to assist her in paying for her nursing school. In less than a week, they raised more than $8000 and presented her with the surprise check.
1.Why did Judy’s family choose TunDe in the end?
A.To help her with a kind gesture. B.To look after Judy in the hospital.
C.To replace another nursing aid. D.To ask her to return the money.
2.How might Chris feel when hearing TunDe’s story?
A.Surprised. B.Nervous.
C.Content. D.Puzzled.
3.What does the whole story mainly tell us?
A.Constant dropping wears away the stone. B.Actions speak louder than words.
C.The truth never fears investigation. D.Kindness comes full circle.

Distinguish Between Work and Home Modes
When working at home, slowly moving from bed to the sofa five minutes before you start can also be your biggest challenge. 1.. It is necessary that you should set yourself up the right way.
* Be realistic
A wide, open day working from home can feel full of possibilities. 145 things on the to-do list? No problem! 2. Instead, be realistic and then possibly achieve more than you set out to, and feel satisfied, rather than feeling disappointed, if you didn't do everything.
* 3.
In the office your day is broken up by everything from meetings to lunch breaks and even toilet breaks, but when you are at home, it can be easy to just work for long, unbroken periods. In order to be productive, you should impose structure on yourself, for example, 45-minute to 60-minute chunks of focused work followed by a short break. 4.
* Take some breaks
It can be difficult to tear yourself away from your laptop, but that doesn't mean you shouldn't take breaks. Leave your desk for lunch and take advantage of being at home to walk the dog for half an hour in the afternoon. You'll return feeling refreshed and more productive for the rest of the day.
* Be sociable
5. Unless you're self-isolating, working from home shouldn't mean that you don't leave the house at all or don't see anyone for two weeks. Ensure you still keep up social interaction. If you're the kind of person who'll miss your colleagues when you work from home, build opportunities for socializing into your day.
A.Work in short bursts
B.Manage disturbances
C.Don't fall into the trap of being over-ambitious
D.However, don't forget that you are there to work
E.Try to call your friends rather than send messages
F.It's hard to maintain concentration in a new environment
G.This can be effective to break the day up and keep focused

To Friend or Not To Friend
We all love our parents and turn to them when we’re in need, but would you like them to hear the conversations you have with your friends on the school playground or lunch queue? Social networking sites have become extensions of the school hallways, so would you add your parents as “friends” and allow them to view your online activities and conversations with friends?
In the past the generation gap included a technology gap, where children were up to date with latest technology and parents were left behind, content to continue their day to day lives as they always had because they had no need to know more about technology. However, more and more parents are beginning to realize just how important social networks are in their lives. This realization has given many parents the motivation to education themselves about social networking sites.
These days many people are attracted to social networking sites because they can choose who they have around them; there’s also a certain amount of control over privacy that we don’t get in real life. Sometimes we feel that privacy is violated when we must accept a “friend” request from a parent or family member.
It’s a difficult choice whether or not to allow a parent to become a part of our online lives. On the one hand we don’t want to “reject” their request because that might hurt their feelings or make them feel you have something to hide. On the other hand if you do accept, then you could have a sense of being watched and no longer feel free to comment or communicate the way you did before.
A recent survey suggested that parents shouldn’t take it personally if their child ignores their request, “When a teen ignores a parent’s friend request, it doesn’t necessarily mean that they are hiding something, but it could mean that this is one part of their life where they want to be independent.”
Perhaps talking with parents and giving explanations would help soften the blow if you do choose not to add them to your friends list.
1.From Paragraph 2, we learn that _______.
A. parents feel secure about their privacy online
B. social networks successfully fill the generation gap
C. parents have realized the importance of social networks
D. social networks offer a platform for parents to communicate
2.Teenagers may refuse a parent’s friend request because _______.
A. they hide something from their parents
B. they are unwilling to be watched by parents
C. their parents tend to fall behind in technology
D. their parents make negative comments on them
3.The passage is mainly about _______.
A. privacy online B. social networks
C. the generation gap D. parents’ friend requests
4.The passage is written mainly for _______.
A. parents B. teenagers C. teachers D. researchers
