Have you ever experienced such an annoying thing as it took so long to open a web page? You're watching stops every few minutes, which ruined your internet experience. But it could be a thing of the past. On June 3, the Ministry of Industry and Information Technology announced that China would issue licenses for the commercialization of 5G. It means major telecom carriers will start to provide 5G services.
The "G" in "5G" refers to the generation of mobile network technologies. 1G let us talk to each other, 2G let us send messages, 3G gave us mobile data and the internet, and 4G made all of these things faster.
Now 5G promises much faster data download and upload speeds, and more stable connections. This means that you will be able to download an entire HD movie in seconds and only experience a short delay between sending and receiving data. For example, when you have a video chant with your friend, there is generally a 100 to 200 milliseconds (毫秒) delay with 4G, but 5G will reduce the delay to 1 millisecond or less, which is almost real time.
With a 5G network, the short delay in information exchange will allow driverless cars to run more safely, as they will be able to communicate in real time and avoid potential dangers. Meanwhile, 5G enabled wearable devices will keep doctors constantly updated on the health status of their patients and warn them immediately if there’s something wrong. Besides, VR games will become more popular with 5G. The short delay of 5G will make the games feel even more real.
Though 5G will make our lives more convenient, it will not be perfect. For one thing, 5G will not "travel" far. On 4 networks, you can be 10 kilometers away from the nearest transmission (传输) base and barely lose signal. But 5G will only cover about 300 meters, meaning we will need more transmitters so that we can get signals. And in order to use 5G, we will have to buy new specially, designed for 5G that are currently expensive.
1.What is the function of the first paragraph?
A.To provide a background of the topic.
B.Tu offer basic knowledge of the topic.
C.To use an example to support the topic.
D.To draw readers’ attention to the topic.
2.According to the passage, what is likely to happen to our life with 5G?
A.Doctors can treat more patients.
B.No drivers are needed in the near future.
C.Many advanced technologies will be further improved.
D.Children will hate playing VR games in the real world.
3.What can he found when 5G is compared with 4G?
A.4G cover smaller areas. B.4G needs more transmitters.
C.5G signals can travel farther. D.5G costs higher in early stage.
4.What is the text mainly about?
A.The development of 5G.
B.Challenges that 5G will face.
C.Benefits that people will get from 5G.
D.The difference that 5G will make to our lives.

高三英语单项填空简单题查看答案及解析
Begin doing the work you love as soon as possible, even if you don’t get paid for it, or if you can only work at it part-time. Albert Einstein was unable to get a job as a physics professor. He could have said to himself, “Well, I just don’t have the work relative to physics. I should give up on it and settle for something else.” Instead, he wrote the two most famous papers when he was employed as a patent clerk. After their publication, there was not a major university in the world that would not have been glad to have him on their staff.
If you want to work as an artist and you are making a living as a waiter, don’t think of yourself as a waiter who hopes one day to become an artist. That puts the work you love somewhere off in the distant future. Rather, think of yourself as an artist, supporting yourself by waiter tables—and paint, or draw as much as you can. It is possible to earn a living wage as a waiter working 24 hours a week. That leaves plenty of time to devote to training or developing your craft（手艺）in the off hours.
While seeking the work you love, it helps to expand your awareness into the universe of all possibilities. You don’t want to be limited to the ideas of what you should do or what you have done before. Having opened to all possibilities, you can make a final decision and select the work you love as your own.
Doing the work you love requires that you be equally comfortable with the imaginative and the practical. It requires the ability to dream big dreams and the ability to face and master all the little details that make dreams come true.
1.According to the passage, perhaps Einstein once said to himself, “_______.”
A．Well, I just don’t have the work relative to physics. I should give up on it and settle for
something else
B．The job is just what I want, I should work very hard at it
C．I have to support myself by working as a patent clerk now, but I won’t give physics up
D．I must wait until I find my favorite job
2.If a person works 24 hours a week, he can________.
A．have enough spare time for his hobbies
B．have no time left to make his dream come true
C．do nothing else
D．make a good living
3.Which of the following is not implied in the last paragraph?
A．Sometimes the imaginative is different from the practical.
B．We have to take care of a lot of details before we make our dreams come true.
C．We shall do practical things rather than dream.
D．We shall dream big dreams and practice as well.
4.According to the passage, the author encourages us to ________.
A．start work quickly B．select job carefully and patiently
C．dream often D．make up our minds quickly

When I was about to go back home, it was dark. In order to get home as soon as possible, I hired a taxi. The car was along the road, now well-lit, now sank in darkness. I broke the on purpose, that the driver might be too tired to drive. “When do you go back home in the evening?” “9 o’clock. I’ll go after this trip.”
“Then when do you come out in the morning?” I another question.

It seems that they have a grievance (不满意) against everything. But this driver told me, “I find it to be a section chief as I was before. I don’t like management work. I like driving, just for . It’s that I drive without a passenger. So I can earn two or three thousand Yuan a month with ease. Any ? Yes, I never follow an empty taxi. If it goes , I go northward. If it goes along the highway, I turn into a street. In this way I always get customers.
His words showed his satisfaction with his life and the pride he in his job. Such feelings are so among people nowadays as oxygen in high mountains. As an ancient saying , “Neither joy in material gains nor grieve over personal setbacks (挫折).” How many people nowadays can show high ideals by simple living and go far with a calm mind? I couldn’t help feeling curious when I found such a state of mind in a stranger on a cold winter night.

FLEA MARKETS (跳蚤市场)
For the best selection of flea market product, get there as soon as it opens on the first day of the market. If it’s open Saturday and Sunday all year round, go early on Saturday morning. For seasonal or annual flea markets, go early in the season, preferably the first weekend. You’ll have first pick of the goods the vendors (小贩) gathered during the year.
For the biggest discounts, it’s just the opposite. Shop mid to late afternoon during the final day, or days, of the flea market. The vendors are tired and ready to get home –and they might just cut you some fantastic deals if you ask. You may have to haggle a bit, but you’ll probably go home with some bargains, especially if you’re buying large, heavy pieces the tired sellers don’t want to pack and load.
YARD SALES
Yard sale shopping is a lot like flea market shopping. You’ll find the best selections when the sale first starts. Go early on the first day of the sale. If the sale starts at 7 am, be there a few minutes before – but not so early that you’re labeled an early bird. Don’t wait until Saturday to visit a yard sale that starts on Friday.
Like flea market vendors, yard sale sellers aren’t as willing to haggle early in the morning, but the prices are usually pretty low to start. Don’t wait until the afternoon bargain hours to shop at yard sales.
THRIFT STORES (旧货店)
For the best thrift store selections, ask the employees when the new product arrives. It could be a certain day of the week or a certain time each day. Find out, and then plan your visits for those days and times.
Thrift store prices are usually low, so you might want to snatch things up as soon as you find them. If the prices seem unusually high, ask about their sale structure. Thrift stores don’t always state their sales clearly and sometimes the sales are confusing. Find out when they discount the items that interest you. That’s when you’ll find the best deals.
1.As for the biggest discounts in the Flea Markets, you’d better______.
A.get there about 6:50 am on Friday
B.go early on Saturday morning
C.ask the host when the new product arrives
D.buy items late afternoon during the last day
2.The best Thrift Store selections should be taken_______.
A.after the sale starts B.as soon as you find them
C.when new items arrive D.before the afternoon bargain begins
3.The text is most probably intended for ______.
A.antique collectors B.economical shoppers
C.product vendors D.wealthy people

Getting a good education is more important today than ever before. It is the best thing you can do to build a better future for your children and yourself.
Most children in Canada attend public schools. Public schools are completely founded by governments through tax (税收) income. Boys and girls attend the same school and share the same courses and classes. Schooling in Canada is provided in English and in French.
The rest of Canadian children attend private schools，which are supported mainly by fees (费) paid directly by parents. Some private schools enroll (招收) only boys or girls.
By law，children must attend school from age 5 to 16.Children are usually in school between 8：30 or 9：00 a．m.，and 3：00 or 4：00 p．m.Monday through Friday，from September to the middle of June. There are several different levels in the Canadian education system. The first is called Elementary Schools. In most provinces Elementary Schools include Kindergarten through Grade 7 or 8.
From Grade 8 or 9 through 12 or 13，children go to Secondary School or High School. High School students must take certain courses for several years，such as English or French and mathematics. Some courses help students get a job after they graduate from school. Other courses prepare students for college or university. In Canada，teenagers usually make these choices for themselves，with the advice of their teachers，guidance counselor (指导教师) and parents.
Schools usually offer extra activities at the end of the normal school day. These include sports，games，music and clubs.
Most elementary and high schools encourage parents to take part in school activities. Parents' nights are organized from time to time. These are chances for parents to discuss their children's progress with teachers. You may wish to bring a friend with you. After graduating from high school，many young adults continue their studies through postsecondary education.

Even if you really enjoy your job, it’ s still possible to battle boredom as you work. You may not be able to make big changes---or change your job---but you can make small adjustments to your routine that can make every day seem, well, a little less routine.
1.Switch Your Seat
Change your outlook at the office by changing your office. Ask your supervisor to help you find a new desk. Even switching desks with a neighboring coworker can offer a fresh atmosphere.
If it's not possible to change your location, see if you can change your desk’s direction. A new view can be just as refreshing as a new location.
2.______________
Start and end your day in a different way. Consider a new mode of transportation, if it’s possible. Take a subway. Ride a bike on sunny days. Carpool with a coworker. Use a new route to get to your job. You needn't change it for ever---just long enough to help you escape the boredom.
3.Find a New Work Style
Sick of attending that long-standing Monday morning meeting? Try to change it to the afternoon.
If you find yourself feeling most bored in the afternoons, try to arrange to do your favorite tasks then and tackle less desirable projects in the mornings.
If you usually communicate with coworkers via email and instant messaging, start dealing with people face to face. Increased communication with coworkers may help improve your mood.
4.Get and Set a Goal
If your work is short of objectives, it's no wonder that work has become boring. Identify a goal and set an “achieve by” date for it.
Your goal needn’t be too ambitious as long as you have enough enthusiasm for it. Perhaps you want to make a new project. Maybe you’d like to pursue a promotion. Or you may even set a goal of finding a new job altogether. Whatever it is, actively move toward an objective.
1.What is the purpose of the passage? (within 15 words)
