The fight is on to get rid of air pollution in our cities. While the best solution in the long-term would be to ban fossil-fueled cars, that won’t help the millions who are dying in the meantime, and so some high-tech solutions are now on the cards.

London’s air pollution problem has been getting worse for years. In March 2016, ten London pigeons became famous. These pigeons took to the sky, wearing backpacks monitoring air pollution. Once in the air, the backpacks sent live air-quality updates to the smartphones of the Londoners below.

Another promising approach can be found in Beijing. A seven-metre-high “Smog Free Tower”, designed by a Dutch scientist, Daan Roosegaarde, opened in Beijing’s 751 D Park in September 2016. It is a huge, outdoor air purifier. Airborne particles (颗粒) are sucked into the tower and caught by a dust-removal plate. Finally, clean air is blown out of the other end. “Changing smog particles does not take much power.” Roosegaarde said.

As for what to do with the collected PM waste, he has currently set up a business making jewellery out of the waste. Prince Charles owns a set of “smog free” cufflinks (袖扣). If collected on at a big scale, Roosegaarde believes it could even be used as a building material.

Mexico City has an alternative solution. Looking to Nature to maximize the surface area of a building, Allison Dring, a Berlin-based architect, managed to catch light and wind from all sides. She is now making a building material by burning agricultural crop by-products in the absence of oxygen. “It means that you are actually taking carbon (碳) out of the sky, transforming it into a material, and then using it to build,” says Dring.

The fight against outdoor air pollution is really just starting. Even if none of the ideas take off, at least Prince Charles’ cufflinks, the special building surface and pigeons wearing back-packs will have brought the issue more to the public’s attention.

    When the Bayside campus of Shekou International School (SIS) are still kept shut because of the COVID-19 pandemic, teaching activities at the school have been resumed online since Feb. 3rd, 2020.

The school is using popular apps and software for online learning. Video conferencing and office automation are used to help teachers keep track of students’ conditions and communicate with their workmates across the world. Teaching online also offers a new experience to the teachers to update their teaching methods and to step out of their comfort zones.

Staying in Phuket, Thailand, science teacher Riley Laird records videos on a 10-year-old green sea turtle named Marlin and the local turtle sanctuary as part of the online classes on ecosystems for Grade 7 students. “I want to connect our learning with the reality. The sanctuary sends us updates on the turtles’ health and progress. They say that Marlin is likely to be released into the sea in mid-June,” says Laird.

Rebecca Wallace is a Grade 4 teacher at the school, staying in her mother’s home in New York. From 8 p.m. to midnight every day, she starts teaching mathematics and arts to her students living in different time zones. Though teaching nearly around the clock, Wallace says that she is getting to know the students better in terms of their homes, family and even pets.

Greg Smith, head of SIS, names the online teaching period a “new normal” at the school. “Students are now more skillful at using technology than before. They see that communication is the most powerful part of being an effective learner and can use the tools to shrink distance and time. The “new normal” will offer more choices for connection to the world and more focus on creating real solutions,” he says.

According to the school, 68% of its students are staying in Shenzhen while 27% of them are staying abroad for the epidemic.

Last Monday, we were having our Chinese class while the teacher suddenly slipped and fall. We were all worried about her. One of the boy carried her on the back, under the help of some others, to the clinic immediately. It turned out that her right leg was breaking and she had to stay in hospital. The following day, we went to visit her with flowers. Seeing her lying in bed with leg wrapped in bandages, we felt sorry for her and hoped that she would recover soon. Lucky, this Thursday she returned back to the class in a wheelchair to give us lessons. We were both deeply moved and proud of have such a responsible teacher.

    Leading health experts from the CDC and the WHO have made it clear that reducing the effects of coronavirus（新冠病毒）means staying hone as long as possible.1.They give some ideas as follows：

Don’t let the news control your rest.

The coronavirns situation seems to change by the hour, resulting in a number of people feeling necessary to constantly check their phones for news. That can not only be stressful at any time, but also it can affect your ability to relax if you surf news before going to sleep. Dr. Rosmarin says, “It’ s not a good time to watch the news.”2.

Don’t argue with people who seem unconcerned about the crisis.

You might face pressure from friends or family to attend gatherings when you aren’t comfortable being in groups. You may be upset because they aren't following the instructions: staying at home. 3.So you’d better avoid the meaningless argument.

4.

Do laundry on Sundays? Keep doing it on Sunday. Not going to work? Get dressed anyway. Maintaining a regular routine will go a long way toward helping you avoid feelings of disorganization.

Don’t hesitate to seek help if you need it.

5.For people already struggling with anxiety, obsessive compulsive disorder, or depression, fears over coronavirus can be especially disruptive. Always seek professional help if depression, you feel overwhelmed.

A.Arguing about it isn’t productive.

B.Don’t ignore your regular routine.

C.You cannot solve the mental problems all by yourself.

D.Don’t forget to remind your family to respect your boundary.

E.What can you do to make your staying home beer than before?

F.But how to deal with the mental tension, such as being upset and nervous?

G.Sleep is important to a healthy system, and giving yourself an opportunity to relax is important.

    Dog owners walked about 23minues longer each day than non-dog owners In a new study, dog owners took 2,760 additional seps—compared to people who didn’t have a dog at home. Bu here’s the real good news: That extra exercise was done at a moderate（适度的）pace, which means it could help adults meet their recommended weekly totals for physical activity.

The research, published in BMC Public Health, focused on adults 65 and older, who tend to be less active than younger people. The study included 43 dog owners and 43 non-dog owners, all of whom were monitored continuously for three week-long periods. When they compared the two groups, the researchers found that dog ownership was associated with a large, potentially health-improving effect.

Dog owners walked about 23 minutes longer each day than non-dog owners, 119 minutes versus 96 minutes on average. They also took an additional 2,760 steps, and had eight fewer continuous periods of sitting down. Most of that extra walking was done at moderate pace, defined as 100 or more steps a minute. Dog owners walked at this pace for 32 minutes a day, versus just 11 minutes a day for non-dog owners.

The World Health Organization（WHO）recommends that adults get at least 150 minutes of physical activity a week. This increased walking time alone could just about satisfy that requirement, say the researchers—so it makes total sense that 87 percent of dog owners in the study met these guidelines, versus just 47 percent of non-dog owners.

Co-author Nancy Gee says that pet ownership may help older adults get more activity or maintain their current activity level for a longer period of time. “This could improve their chances of a better quality of life, improved or maintained cognition（认知）, and perhaps, even overall longevity（寿命）,”she said.

Here at Health, we’ ll add that caring for pets has been shown to have plenty of other physical and mental health benefits, as well. As animal lovers ourselves, we’ re happy to add one more to the list.

1.What can we learn about the research？

A.It was targeted on old people.

B.It was sponsored by the WHO.

C.It had an undesirable effect on dog owners.

D.It took the mental health of dog owners into consideration.

2.What does the author intend to do in Paragraph 3？

A.To present the results of the research.

B.To show the guidelines of the research.

C.To describe the process of doing the research.

D.To explain the reasons for conducting the research.

3.What does Nancy Gee think of owning a dog?

A.It is too expensive.

B.It is time-consuming.

C.It enables older adults to live a healthy life.

D.It helps young adults to keep a healthy routine.

4.What is the best title for the text?

A.Non-pet owners enjoy more pleasure

B.Animal lovers are more generous

C.Young people walk less today

D.Dog owners walk way more

    Travelers to the Arctic islands of Svalbard would find a rough, ice-hardened land, sheltering polar bears in its frozen landscapes. This group of Norwegian islands is the land of the “midnight sun” with almost 24 hours of sunlight during the winter months. It is also home to one of the most important storage facilities in world farming — the Svalbard Global Seed Vault.

The seed vault was opened in 2008 in an effort to safeguard the world’s food supply for future generations. Svalbard is the perfect frozen environment to house seed samples, set inside an Arctic mountain at 130 meters above sea level, so it is unlikely to be flooded. Low humidity , geological stability, and the surrounding permafrost can keep seed-keeping places cool, dry, and usable for centuries.

Seed gene banks from around the world have sent food crops seeds for safety in case a natural disaster or environmental damage destroys existing supplies. Worldwide there are more than 1.700 seed gene banks that store seeds locally and many choose to send back-up samples to facilities like the Svalbard’s vault.

There is space in the global vault for 4.5 million different crop varieties with each variety storing on average 500 seeds, meaning it can house 2.5 billon seeds. There are around one million seed samples from 80 institutes in the vault at present so there is a lot of spare capacity for the vegetables, grains, peas and beans that are banked annually. On the top of that, there are rare flowers from the Myanmar rain forests.

The largest numbers of samples in the vault are varieties of rice and wheat. The seed vault has been listed as one of the most influential projects of the past 50 years for its efforts. Seeds themselves are not kept for farmers or gardeners to grow produce. Their true value is as a genetic resource in plant upbringing to create new crop varieties.

1.What makes Svalbard a global seed vault?

A.Its eco-friendly tourism. B.Its rich supplies of food.

C.Its favorable environment. D.Its strong sunlight in winter.

2.Why do many seed gene banks send food crop seeds to the Svalbard’s vault?

A.To protect them from climate changes. B.To exchange them for new crop seeds.

C.To make sure of the safety of food supplies. D.To compare them with new crop varieties.

3.What can be inferred about the Svalbard’s vault from Paragraph 4?

A.It values plant different types of plant. B.It has little space for newcomers.

C.It is costly for most institutes. D.It sees a big increase in seed samples every year.

4.What is the author’s purpose in writing the text?

A.To explain how to store seeds safely. B.To introduce an influential seed vault.

C.To seek sponsors for world seed vaults. D.To call on seed institutes to work together.
