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.

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 is the best time to do them. 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.

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 networks. 5G is also expected to unlock the 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 networks. While most nations will have 5G by updating existing foundations, the study noted that China plans to build part of its 5G networks.
A 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 nation’s 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 will 5G bring?
A.A completely new pattern for daily life.
B.Excellent networks and national safety.
C.Amazing speeds for public transportation.
D.Realizing the potential in many new services.
2.What is the future of 5G in China?
A.It will develop rapidly. B.It may be lack of government support.
C.It will move forward slowly. D.It may fall behind Europe.
3.Which of the following best explains “erect” underlined in paragraph 4?
A.bring up. B.set up.
C.turn up. D.pick up.
4.What can we infer from the last paragraph?
A.Some Chinese will use 5G in 2025.
B.Koreans cannot own 5G in 2025.
C.Only five countries will have 5G in 2025.
D.Europe will pay little attention to 5G in 2025.

My senior high school life started with military training(军训). It consisted in two parts: the theory exam and the physical training, which was lasted about two weeks. The latter was much tough than the former. Dressed in green uniforms and exposing to the sun, we had to follow the soldier daily routine and go through hard training. Each morning, we had to get up and fold quilts rapid. We should finish our meals in limited time, too. Then I think it unbearable. Besides, now looking back, I find it necessary. It is the military training which teaches me how to bear hardship and lead better life.
