The race to 5G is on. All four major US carriers now have some form of 5G wireless, although it’s all limited roll-outs in only a few cities, mostly using expensive phones that won’t support future nationwide 5G networks. We’re tracking the roll-outs monthly on our Race to 5G page.

The early 5G roll-outs are more like a public test than a final product. AT＆T, Verizon, and T-Mobile are all using technologies that only travel about 800 feet from a cell site, which means there isn’t much coverage. All four carriers are waiting for upgrades（升级）to their base stations that will improve coverage, speed, and reliability. Around the end of this year or the beginning of 2020, AT＆T, Verizon, and T-Mobile all intend to launch 5G networks that use the existing 4G spectrum（频谱）, which will have slower speeds but broader coverage.

We’ve tested AT＆T in Dallas and Las Vegas Sprint in Dallas and New York; Verizon in Chicago, New York, and Providence; and T-Mobile in New York. Every month, we’ve been seeing better performance and more new devices. It’s messy. It’s very early days. And if you like new technology, it’s very exciting.

In previous mobile transformations, we’ve seen most of the big changes happening years after the first announcement. Take 4G, for instance. The first 4G phones in the US appeared in 2010. But the sorts of 4G applications that changed our world didn’t appear until later. So following that plan. While we’re getting a little bit of 5G right now, you should expect the big 5G applications to crop up around 2021 or 2022.

5G stands for fifth-generation-cellular（蜂窝状的）wireless, and the initial standards of it were set at the end of 2017. But a set of standards doesn’t mean that all 5G will work the same-or that we even know what applications 5G will enable. There will be slow but responsive 5G, and fast 5G with limited coverage.

1.What is the present state of 5G in the US？

A.Initial exploration. B.Great improvement.

C.Wide application. D.Extensive promotion.

2.Why does the author take 4G for example？

A.To persuade carriers to give up 5G.

B.To remind people of 4G’s importance.

C.To prove 5G takes time to make a greater difference.

D.To show 5G has failed to meet expectations.

3.What’s the author’s attitude to 5G？

A.Cautious. B.Skeptical.

C.Opposed. D.Objective.

4.What’s the best title for the text？

A.Race to 5G B.5G is coming

C.How fast is 5G？ D.What is 5G？

It is obvious that all of our childhood memories are not accidental. When you are a child, every scent, every sound, every move, every toy, the first day of school, the first kiss, the first step. . . Everything together makes what is the personality of a man. All these are pieces of one whole entity.

I was about 6 years old. My mom's best friend left to another town and asked my mom to stay at her place with me for two days in order to look after her two sons. One was a little older than I was. and the second boy appeared to be super grown-up, for he was already fourteen. I always enjoyed staying at their place.

I remember the second day we were supposed to have the come-back party for my mom's friend at her place. I woke up. Mom went to work and reminded me to be nice and clean by the time she came back. I stayed with Tony, the older of the boys and suddenly somebody called him and though he was not permitted to leave me alone-he left. He said it would not be long. But it took him forever. I realized that I was alone. I could not come out of the house, so I opened the window. I was so desperate. So lonely. So betrayed. At that moment I pulled the curtain so strongly that I fell on the floor. And there I was standing-one little criminal-desperate to escape and knowing that I would be punished for destroying the curtain that was not even ours.

But then something changed. I stopped weeping. I looked around and realized that I was in a safe place, and that mom would come back and kiss me no matter what I had done.

This was a moment of pure happiness, not the happiness of getting a new toy or a dog, or going to the party of your best friend. It was the moment of clarity for me-the first time in my life when I realized that I was happy to have my mom and that I was safe. My eyes saw the world in different shades that moment. And by the way-I was not punished for the curtain. I fell asleep on my mom's knees.

1.What is the best title for this passage?

We’ve all heard about the power of our attitude, and it’s our attitude that determines how much we succeed in life.

All the things that you have been through, all the people you have met and interacted with can have an impact on your attitude. If you think that all these factors have molded you into a person with a poor attitude towards life, there is no need to worry. 1.

Identify and understand what you want to change.

The first step towards change is clearly understanding what needs to be changed. 2. When it comes to changing your attitude, you need to do an honest and in-depth self-evaluation so you could point out exactly which of your traits need to be improved or totally changed.

3.

Find someone who has the kind of attitude that you want to have, and let his or her life give you inspiration and encouragement to move beyond your temporary failures in your journey towards becoming a better person.

Choose the right company.

As they say, “Bad company corrupts good character.” You don't expect yourself to be able to change if you go on surrounding yourself with people who possess all the negative traits that you want to change. Consider befriending new people, especially those who are optimistic and have a healthy attitude towards life. 4.

Believe that you are able to change.

5.If you don’t believe in yourself or believe that you or your life can change, it just won't happen—you will either never start, or give up quickly that you won't have even given yourself the opportunity to succeed.

A. Look for a role model.

B. There is always an opportunity for change.

C. Setting clear goals is the key to success in any endeavor.

D. Think about how your attitude change will affect your life.

E. The greatest obstacle is our inability to trust in what we can do.

F. Your effort to change will be easier with these people as friends.

G. Fix your mind on the things that would come as a result of your attitude change.
