    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 your 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 U. S. top out at an average of 19.42 Mbps. But by comparison 5G promises gigabit (千兆) speeds.

“5G is one of those signs, 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, but also connected infrastructure (基础设施) construction. There’s lots of data behind that task, which is why we need high speed.

Augmented reality glasses and virtual headset haven’t yet broken the mainstream, but tech companies are joyfully betting that these devices will eventually replace our smartphones. With 5G, that could actually happen. This is notable because companies such as Apple are reportedly developing AR glasses to assist — or perhaps even replace — smartphones.

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’s 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 does the author want to stress in Paragraph 1?

A.The lighting-fast speed of 5G.

B.The expectation of 5G world.

C.The difference between 4G and 5G.

D.The internet-connected devices in our life.

2.What does the underlined word “emblem” in Paragraph 2 mean?

A.Exhibition. B.Success.

C.Symbol. D.Explanation.

3.We can infer from the text that ________.

A.5G world won’t come without AR glasses

B.5G helps to create the artificial intelligence vehicle

C.Apple company is developing AR glasses worldwide

D.Tech companies will face the fact that smartphones may be replaced

4.What will the author probably tell us next?

A.How to fully expand 5G coverage.

B.Smart glasses will become faster and lighter.

C.Why 5G isn’t concentrated in big cities.

D.The importance of infrastructure construction.

 

1.A 2.C 3.D 4.A 【解析】 本文是一篇说明文。文章讲述的是随着科技的不断发展,5G时代即将来临。它最大的优势就是上网速度大大加快。 1.推理判断题。​首段先提出5G时代即将来临,接下来介绍5G上网下载的高速度,相比于目前的4G,5G有望达到千兆的上网速度。作者在第一段想强调5G的超级速度。故选A。 2.词义猜测题。划线词后的and that is to say, it is a sign of time(也就是说,这是时间的标志)是对前面的补充说明。由此推知,划线词的意思是“标志,象征”。故选C。 3.推理判断题。根据第三段中This is notable because companies such as Apple are reportedly developing AR glasses to assist — or perhaps even replace — smartphones.(这一点值得注意,因为据报道,苹果(Apple)等公司正在开发增强现实眼镜,以帮助——甚至取代——智能手机)可知,我们可以从文中推断,科技公司将面临智能手机可能被取代的事实。故选D。 4.推理判断题。根据最后一段But don’t get too excited. There’s 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.(但是不要太激动。与此同时,仍有很多工作要做,包括各种试验,以确保收音机能很好地配合硬件和基础设施建设,这样5G就不会只集中在大城市)可知,作者接下来可能会告诉我们“如何全面扩大5G覆盖。”故选A。

    For some people, higher education is not just a goal in life, but also an expectation. In the United States, if your parents attended a college or university, there is a good chance that you will, too. Even if your parents did not go to college, you still have a good chance of completing higher education if your family is wealthy.

But your chances are reduced if you come from a needy family, a community with limited educational resources or you simply have no one to follow as an example.

Helping those in need is one of the main ideas behind a strategy of behavioral science called nudge(轻推)theory or nudging. Nudging is a way of changing people’s behavior through indirect suggestion and by supporting positive actions.

A growing number of U.S. colleges and universities look to nudging as way to support poor, minority and first-generation students. They also are using it to increase overall graduation rates. Two common forms of nudging are emails to students and text messages to their mobile phones. Schools and other educational organizations keep in contact with students this way, offering advice and help when needed.

However, Alejandra Acosta---a higher education policy expert at New America notes that there are several qualities a nudge campaign must possess in order to be successful.

Acosta says messages must be timely, meaning they reach college students well before the date by which a student is required to take action. Additionally, nudges should be written clearly and provide as much information as possible. If students start to struggle in class, school officials should not just message them, saying they should seek academic support. The message should give information about what kinds of support the college or university offers and exactly how the student can make use of them. That is why nudges should possess interactive qualities, Acosta says. For example, students should be able to ask questions of school officials or be directed to a website for more information. In addition, colleges and universities must ensure their support services are in place and working as best they can.

When nudges work, they can do a lot of good. In 2018,a nonprofit group launched a nudging campaign at four U.S. community colleges. They worked with nearly 10,000 first-year students at three such colleges in Ohio and one in Virginia. A recent study found that older and minority students who agreed to receive these nudges were 16 to 20 percent more likely to continue into their second year than those who did not.

1.Who is most likely to receive and complete higher education according to the passage?

A.Tony, whose father is the only bread-winner in the family.

B.Jimmy, whose mother is a worker in a small factory.

C.Betty, whose grandmother is a housemaid of a famous university professor.

D.Cathy, whose parents failed to attend college but succeeded in starting a big company.

2.What can we know about nudging?

A.It is rooted in psychological science.

B.It is a way to improve people’s mind.

C.It offers useful and direct advice in time.

D.It helps students via emails and text messages.

3.What is the passage mainly talking about?

A.The problem with higher education.

B.A way for colleges to support students.

C.The popularity of nudging campaign.

D.A national campaign dealing with poverty.

4.Which of the following messages can be employed by nudging?

A.You are supposed to talk to your consultant about your English literature. If not, you are likely to fail the course. Do it as soon as possible.

B.Your performance in English literature is not good. It will be a good idea if you can share your difficulty with your classmates.

C.Dr. Smith is a professor in English literature. He is available every Thursday afternoon from 3 pm to 6 pm. Call 210-432-67 to make an appointment.

D.Do you need any assistance in English literature? If so, we can make an appointment with Dr. Smith for you. It is free of charge.

I have many hobbies and I think fishing put at the top of the list. It is for fishing that has helped me improve my self-control.

My study was not satisfactory because of my impatience three years ago. When seeing that, my father comes up with a good idea and taught me why to fish to overcome my shortcoming. Telling that fishing was full of funs, I followed him without hesitation. Actually, fishing turned out to be more difficult than I had expected. To grasp a skill, I tried hardly and became a skilled fisher. It is amazed that I can focus on my study now. I'd like to share my experience with those who have the same trouble, encouraging them to study with our full devotion and attention.
