China will have the most 5G connections of any nation by 2025, according to a new study, while Europe will fall behind Korea, the United States and Japan in terms of 5G penetration (渗透) by that year.
5G is the fifth generation of network technology. It is expected to bring unbelievable speeds to Internet users, with some operations running 10 times faster than on 4G network. 5G is also expected to unlock potential in a lot of new services, including artificial intelligence, science of robots, self-driving cars, and the Internet of things.
The GSMA said that China’s three major mobile operators—China Unicom, China Mobile, and China Telecom—are already moving ahead with 5G works. While most nations will have 5G by updating existing foundations, the study noted that China plans to build part of its 5G networks.
One of the major distinguishing factors between Chinese mobile operators and those in the rest of the world is the intention to erect the new and independent 5G networks. That is, China is determined to build a completely advanced 5G. The high cost underlines China’s seriousness about paying whatever it takes.
Korea will lead the world in terms of 5G penetration in 2025, when 66 percent of the nations’ total connections will be 5G, according to GSMA. This compares to 50 percent in the US, 49 percent in Japan, 36 percent in China, 30 percent in Europe, and a global average of 18 percent. Out of the five economies leading on 5G, Europe will have the lowest participation in 2025, as the area is moving more slowly in having its 5G networks.
1.What is the future of 5G in China?
A.It will develop rapidly. B.It may be lack of financial support.
C.It will move forward slowly. D.It may fall behind Europe.
2.Which of the following best explains “erect” underlined in paragraph 4?
A.Bring up. B.Set up.
C.Turn up. D.Pick up.
3.What can we infer from the last paragraph?
A.Some Chinese will use 5G in 2025.
B.Koreans cannot possess 5G in 2025.
C.Only five countries will have 5G in 2025.
D.Europe will pay little attention to 5G in 2025.

Parents can begin good organization (条理) habits with preschool-age kids, Experts recommend asking them to do small, simple actions on a regular basis with the help of parents. Maybe they open their bags and bring their lunch bag to the kitchen, or take their shoes off at the door and put them in a nearby closet. These won’t save parents much time but they will help develop good habits.
When kids enter primary school, they should be ready for more responsibility. This is the time to teach them about daily routines, and help them take control over theirs. Parents and children might sit down together and make a list of everything that needs to be done to get out of the house in the morning, or get ready for bed at night. Together, parents should figure out how long each activity takes, and when the best time to do them is. Some of the kids might want to get their bags ready and pick out their clothes the night before.
It’s also wise to create a firm schedule for homework. When do kids do their homework? How long do they need? Where do they do it? Where will the homework go once it is done? Figure them out and stick to the schedule as much as possible.
Parents should print up these task lists and help kids finish them step by step. Kids might even check them off each morning or evening. Also, make sure there are clocks in the rooms in which these tasks will take place. Time management is an important part of learning organization, but it can’t be done if kids don’t know what time it is.
Organization gives kids the chance to make it possible to focus on a task and complete it. Kids tend to be more motivated to learn organization skills if they see organization as a challenge to overcome, rather than a fault to repair.
1.Why are kids advised to do small and simple actions?
A.To save parents time.
B.To join a school organization.
C.To help kids form good habits.
D.To form a good relationship with others.
2.What should parents do to help kids develop organization skills?
A.Offer some suggestions only.
B.Finish the daily tasks for kids.
C.Assist kids in finishing the daily tasks.
D.Let the kid finish the daily tasks alone.
3.What does the author think of organization for kids?
A.It is a fault to repair. B.It is nothing special.
C.It is easy to achieve. D.It is a helpful skill.

Global warming is the increase of the earth’s average surface temperature due to the effect of greenhouse gases, for example, carbon dioxide, which trap heat that would otherwise escape from the earth. After the trees are cut down and more greenhouse gases are released, the “blanket” around the earth called the ozone layer (臭氧层), will get thicker. This catches more heat and makes the earth hotter. Luckily, there are many things that every citizen of the earth can do to help reduce the effects of global warming, and it’s never too late or too early for children to take action.
The children should learn what a carbon footprint is. A carbon footprint is the amount of carbon and greenhouse gases people make as they lead the daily life and go about the normal activities. In other words, the carbon footprint is a measure of the environmental impact (冲击) the life has. To live an environmentally friendly life that doesn’t contribute to global warming, people want to have the smallest carbon footprint possible.
Almost everything people do contributes to global warming and is related to fossil fuel consumption. These can be direct uses of fossil fuels, like riding in a gasoline-powered car, or indicrect contributions to greenhouse gases, such as eating fruits or vegetables that had to be shipped from far way to reach their tables.
If a child wants to make a contribution to reducing global warming, he should ride a bicycle to the near park, school, his friend’s house, or anywhere else instead of taking the car. Or he may try to walk or jog, which is also helpful. In addition, although trains and buses often run on fossil fuels, on average, each person uses less energy and produces less pollution to run. Next time if children with their parents have to get around town or it’s too far to walk or bike, take the bus or other public transportation instead of asking for a ride.
1.What is the first paragraph mainly about?
A.A brief description of carbon footprint
B.The serious water pollution.
C.The protection of ozone layer.
D.The causes of global warming
2.Which of the following can describe the carbon footprint?
A.Useless. B.Expensive.
C.Helpful. D.Attractive.
3.What can kids do if they want to help reduce global warming?
A.Go to the near park by bus.
B.Walk or cycle as much as possible.
C.Keep staying at home or school.
D.Go around the town with parents by car.
4.What can be a suitable title for the text?
A.What Can People Do to Use Less Energy?
B.How Can Kids Help Reduce Global Warming?
C.How Does Carbon Footprints Measure Pollution?
D.Why Global Warming Affects Humans’ Life?

Esmee Russell, head of the Stroke Association, said, “A stroke can happen to anyone, at any age, at any time.
