Chinese companies lead in global 5G patent applications with Huawei taking the crown, according to a report by IPlytics, an authorized patent data company. Three companies from China were included in the top 10 list of 5G Standards-Essential Patents (SEPs) family owners, Huawei ranked first. ZTE Corp and China Academy of Telecommunications Technology (CATT) grabbed fifth and ninth places.
Chinese companies topped the list with most 5G SEPs applications in communication systems by the end of April 2019, accounting for 34 percent of the world's total. Chinese tech giant Huawei has taken a leading role by owning 15 percent of SEPs, according to the report "Who Is Leading the 5G Patent Race?"
SG SEPs are patents that any company will have to use when carrying out 5G and no one can avoid them.
Different from 3G and 4G technologies, 5G technology will influence various industries and encourage the appearance of many new products, services and industries.
The automotive sector will most likely be one of the first industries to depend on 5G, which will connect vehicles to other vehicles, roadsides, traffic lights buildings and the Internet according to the report.
"It is 5G that is going to be a huge jump forward for communication systems because only with 5G's higher bandwidth can a number of applications be more advanced and used by most consumers," said Nicole Peng, senior director of the market research company Canalys.
As 5G technology has combined various industries and technologies, the number of 5G SEPs rose to more than 60,000 globally by the end of April 2019, the report said.

Which part of the world has the most nearsighted students? Just look around you– it’s East Asia. Nine in ten school leavers in major East Asian cities are nearsighted, according to the BBC. Experts say books and video games are not to blame (责备). East Asian students, they say, aren’t getting enough sunlight.
People become nearsighted because their eyeballs grow out of shape and light entering their eyes cannot focus correctly. The body can produce a chemical called dopamine (多巴胺) to stop eyeballs from changing shape. And guess what scientists have just discovered? Sunlight can help our bodies produce more dopamine, reported AFP.
According to the study, primary school students in Singapore spend only 30 minutes outdoors every day; in Australia, by contrast (相反), kids spend about three hours a day outside. As a result, fewer children in Australia are nearsighted – only 10 percent, compared with 90 percent in Singapore.
“Children in East Asia just go to school, go home and stay inside. They study and they watch television,” Ian Morgan of the Australian National University told AFP.
But being a bookworm or a couch potato does not directly harm the eyes, added Morgan. “As long as they get outside, it doesn’t seem to matter how much study they do,” he explained. “There are some kids who study hard and get outside and play hard and they are generally fine. The ones who are at major risk are the ones who study hard and don’t get outside. As a result of massive (巨大的) educational pressures and the construction (构成) of a child’s day, the amount of time they spend outside in bright light is minimized.”
Experts suggest children should stay outside for two to three hours every day. This can include time spent in the playground and walking to and from school.What is the main reason for the large number of nearsighted students in East Asia?
| A．Too much reading or gaming. | B．Being short of sunlight. |
| C．Genetic (基因) reasons. | D．Being short of exercise. |
How long do experts suggest children stay outside every week?
| A．Two to three hours. | B．Fourteen to twenty-one hours. |
| C．Two to three days. | D．Over twenty-one hours. |
In the writer’s opinion, why can’t East Asian students get enough bright light?
| A．Because they don’t like sports. |
| B．Because their parents don’t allow them to. |
| C．Because they have great pressures from study. |
| D．Because they spend more time playing video games. |
According to the passage, which of the following statements is TRUE?
| A．Dopamine is a chemical that causes eyeballs to grow out of shape. |
| B．Dopamine can stop light entering the eyes from focusing correctly. |
| C．Spending time in the sun can make the loss of dopamine in the body. |
| D．The more dopamine a person has in their body, the better eyesight he or she has. |
Have you ever been sad because you failed in something? If so, please remember, for often, achieving what you expect is not the most important thing. Here is a story to tell you why.
One day a little boy decided to dig a hole behind his house after watching a science program. As he was working, a couple of boys stopped by to watch. “What are you doing?” asked one of the visitors. “I want to dig a deep hole all the way through the earth!” the boy answered excitedly. The older boys began to laugh, telling him that it was impossible to do it. Then they left.
The little boy kept on digging and digging. Suddenly, a few small colorful stones caught his eyes. He collected them and put them into a glass jar (罐) patiently. Humming (哼唱) a song, he went on digging. The jar was full soon. Then he talked to himself calmly and proudly, “Maybe I can’t finish digging all the way through the earth, but look at what I have found in the process (过程) of digging!”
The boy’s goal (目标) was too difficult, but it did cause him to go on, in other words, to cause us to keep working!
Not every goal will be achieved. Not every job will end up with a success. Not every dream will come true. But when you can’t achieve your goal, maybe you can say, “Yes, but look what I’ve found along the way! There are so many wonderful things that have come into my life because I tried to do something!” It is in the digging that life is lived. It is the unexpected joy on the journey that really has a meaning.What did the boy do after watching a program?

I would like to talk to you about one of the most beautiful places I’ve ever seen. I was born and raised there and now I visit it from time to time. My family moved to the city, so I only go back to see friends or to camp and fish.
I grew up in a small town called Antonito Co. It is surrounded by mountains. So camping is a big source of happiness in the valley. There are so many beautiful places to hike.
The town itself is very small. It is said that if you blink (眨眼) when you’re going through it, you’ll miss it. This has some truth in it considering the size of the town. We have one grocery store (杂货店), a tiny post office , and a tiny bank. There are also a few gas stations, bars, some excellent restaurants, a small hospital and of course several schools. However, for clothing and shoes, you have to drive thirty miles to Alamosa to shop there.
Everyone in the town is nice and we all know each other. The crime rate (率) is zero unless you count some weekend fights that break out because some people drink too much. The classes in school are small, so you get a lot of attention from the teacher.
You’re probably wondering why I don’t live there. Well, I can’t get a job there. A lot of the businesses are family-owned. And they never fire(解雇) their employees. So the employees work there usually until they retire(退休). Most people have to go to other places to get a job. What can you find in the writer’s hometown?
a. bank
b. a post office
c. some gas stations and bars
d. a clothing store
e. a shoe shop
f. some restaurants and a hospital

The aim of students who came to school is to study. But to study requires a right way，or you waste either the time or the money. The following are the ways of studying.
The best time for reading is morning，because in the morning，the air is fresh and the mind is clear. For that reason，we can get good results.
In studying we must have patience. If we have not known a text well，we must read it again. We should not read the next one till we have learned the first one.
When we are studying，we must put our hearts into the book，or we can get nothing from the book while we are reading.
We must always ask “whys”. If it is not well understood，write it down and ask our teachers or our parents，or friends. In any possible way，we must know it completely and what we've learned can be used well and made better.
Though there are many ways for studying，yet the above mentioned (提到的) will be quite enough if we can keep them in heart and do so. What does this passage tell us?
