“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.

Being successful means different things to different people. 【1】 My point is, the specifics involved in finding success can vary greatly, depending on your goal.

There are three basic components necessary for finding success, regardless of the specifics of your pursuit. And, since the desire for ownership is the driving force behind acquisition, I’ll use the word OWN as my simple three-item method for success.

1.O-Opportunity: one of the most important components in finding success is being able to identify opportunity. It is to success what wind is to sailing. 【2】 Identifying opportunity is the first step; awareness sets your sails for success while your motivation provides the wind.

2.W-Wisdom: By definition, wisdom is the accurate application of knowledge. 【3】 It requires clear understanding, great insight and good judgment. Once opportunity is identified, you must use all your inner resources to seize it and make the most of it. 【4】 Finding success when opportunity presents itself often means reaching out for help in areas where you have weakness.

3.N-Never give up: This might possibly be the most important for success. The key is to first break your goal down into workable parts so you don’t feel pressured, and then to work each part at ease with both enthusiasm and purpose. It takes a lot of time, effort and determination to succeed. 【5】

A.Being successful demands doing well.

B.But wisdom involves more than just knowing.

C.You simply can’t have one without the other.

D.Having this attitude keeps you moving in face of trouble and becomes the driving force.

E.Besides, wisdom means knowing your limitations.

F.You’ll finally succeed if you follow these steps.

G.The road to success is being largely determined by what result you want to achieve.

增加：在缺词处加一个漏字符号（Λ），并在其下面写出该加的词。

删除：把多余的词用斜线（\）划掉。

修改：在错的词下划一横线，并在该词下面写出修改后的词。

注意：1. 每处错误及其修改均仅限一词；

2. 只允许修改10处，多者（从第11处起）不计分。

How have you been? I miss everyone. Fortunate, my new classmates are friendly to me. Because it's farther south, all plants here are difference. It doesn't even snow in winter. I suppose I won't need that blue coat any longer. Last night, I asked your mom if you could visit me and stayed for this whole weekend. I said she could show you around this place and we could go swimming in the lake. Your mom said it was fine, what was surprising. She thought it would be wonderful experience for you. I was such excited that I forgot to express my thank to her. Remember to bring your swim suit purchasing in the supermarket before you have come.

【2】It can be something as simple as going to a new restaurant for lunch, cooking something completely new, or visiting a friend in the next town for the weekend. New sensory stimulation can help refresh memory.

Another easy way to improve memory is to use one's non-dominant hand to do simple tasks. For example, if one is right-handed, the left hand could be used to brush teeth or comb hair.【3】But in fact, a part of the brain is being used that is rarely put to work, making the brain stronger.

【4】This might include studying a new language or researching how to do a math problem. And it does not have to be something traditionally thought of as brain stimulating. Learning a new craft or sport may also activate the brain in new ways.

Not only can mind exercises improve memory, but physical exercise can as well. Studies show that exercise can improve memory abilities as it increases blood circulation and therefore more oxygen can reach the brain.【5】

A.This may feel slow and ineffective.

B.Short-term memory is often the first to suffer.

C.Talking with others can also improve one's memory.

D.Even as little as 30 minutes of walking each day can help.

E.Memory exercises can also be accomplished by learning new things.

F.One type of memory exercise involves changing one's regular routine.

G.Being alone can cause stress and depression，which affects memory negatively.

Possible Limitations of Online Learning

If eLearning, however, is not based on solid instructional design theories and models it may lead to the following limitations:

1. It may be a "solo" act.

It is true that, although online learning might be convenient and flexible, it is also a solo act. It will not be easy for all of your learners to feel comfortable when participating in online discussions and engaging more actively with their online instructors or their virtual classmates. Some people absolutely need personal contact with their educators or trainers in order to learn successfully. Furthermore, some types of learning problems may be difficult to be addressed online, and some questions can be lost in a sea of requests and inquiries. 【1】

2. 【2】

However hard we try to fully transfer human communication to online platforms, however natural it seems to form relationships behind computer screens, a virtual environment is just not human. Nothing can replace human contact. Besides, using a computer or a tablet all the time can cause poor vision, strain injuries, and other physical problems. Consider sending guidelines about right sitting posture, desk height, etc. along with your eLearning course; it might be very useful to your audience.

3. It requires self-discipline.

If your eLearning audience lacks self-discipline, it is unlikely that they will be motivated to self study. Traditional learning and training have the benefit of easily tracking both progress and falling behind. 【3】

4. Possible lack of control.

However carefully you design your eLearning course, there is no guarantee that your messages will get across. You offer your learners control over their eLearning experience, but are they going to use it effectively? There is always the risk of your learners just going through the material without paying any attention. 【4】 Unless you know exactly what you’re doing with new technologies, it is very likely that you overwhelm or distract your audience.

Creating effective online learning courses requires knowledge, time, experience, commitment, great communication skills, and a true passion for learning. If you’ve got all that, then be sure that the advantages of your online training outweigh its limitations.

A.It may be impersonal.

B.If your eLearning content is not built to make the most of the medium it will easily become disengaging.

C.This sometimes makes learners feel they lack support and reassurance.

D.It may harm your mental health.

E.Online learning requires some IT literacy, yet not every one of your learners has much experience of computers.

F.This works for many learners as well, as some people prefer their progress to be closely monitored in order to perform.

Standing desks have been praised for their positive effects on physical health, reducing sitting time and lowering certain health risks linked to a sedentary( 久坐的) lifestyle. But could standing desks have positive mental effects?

New research suggests that students may think best when they are on their feet. It offers some of the first evidence of mental benefits of standing desks in classrooms.

Testing was done on high school freshmen who used standing desks, evaluating them at the beginning and end of the school year. Dr. Ranjana Mehta, an assistant professor at the Texas A&M School of Public Health, led the experiments aiming to assess standing desks’ mental benefits.

Through computerized tests, students’ executive functions were evaluated. Executive functions are the cognitive skills used to analyze tasks and break them into steps, and are directly related to academic needs like time management, memorizing facts and solving multi-step problems. These functions are largely controlled by frontal(前额的) brain regions, so researchers used a portable brain-imaging device to examine any related changes.

“Test results indicated that continued use of standing desks was associated with significant improvements in executive functions and working memory abilities,” Mehta said. “Changes in corresponding brain activation patterns were also observed.”

“Interestingly, our research showed the use of standing desks improved mental function, which is consistent with results from previous studies on school-based exercise programs,” Mehta noted.

Policymakers, public health professionals and school administrators should consider the positive effects of standing desks and make some simple changes in classrooms that will have the potential to increase energy expenditure and develop cognitive skills. That would be a valuable contribution to the educational world.

Even today, it is still possible for people to achieve financial success without much education, but the number of situations in which this is possible is decreasing. In today's more complex world, the opportunities for financial success is closely related to the need for education, especially higher education.

Our society is rapidly becoming one whose chief product is information, and dealing with this information requires more and more specialized education. In other words, we grow up learning more and more about fewer and fewer subjects.

In the future, this trend is likely to continue. Tomorrow's world will be even more complex than today's world, and, to manage this complexity, even more specialized education will be needed.

Recognize what skills you are good at. Everybody wants money. But many fail to realize that money is the extension ( 延伸) of your skills, so the most important aspect of learning to make money starts by knowing what skills you have. Make a list of your skills and you should see where your strengths lie. The goal with this exercise is to recognize what skills you are good at naturally. Make good use of them until you finally change more of your skills into usable abilities for your business.

Make use of your confidence to create belief. Confidence is a result of repeating one thing. The more you practice doing something, the more confident you become in the process needed to see it to the end. Starting a business requires confidence, so most people who have zero confidence in the process fail to get started because it is an unknown area. You have to believe in the idea, the process and the ability within yourself to bring your business project to life. Without confidence, belief doesn't exist; without belief, the chances of giving up are high.

Allow your love to become enthusiasm. The last ingredient outside of your skills and confidence is the ability to focus on ideas that you feel enthusiastic about. Having passion will push you to struggle for something you love and turn that longing into action. The goal is to identify topics of interest so that you can start showing some aspects of passion as you start your project. The closer a project is to your heart, the less pessimistic you will become when results don't go your way.

【1】What can we learn from Paragraph 2?

A.It is very difficult for us to know our skills.

B.Knowing your skills is the first step to learn to make money.

C.To recognize your skills will surely make your business successful.

D.To recognize your skills is more important than making money.

【2】What's the importance of enthusiasm for us?

A.It can help us find out what we love.

B.It can make us never feel pessimistic.

C.It can push us to work hard on our goals.

D.It will make us succeed in whatever we are doing.

【3】What does this passage mainly talk about?

A.The advantages of confidence.

B.The ability to focus on ideas.

C.Why people want to be an entrepreneur.

D.How you can go from ideas to an entrepreneur.
