Somebody gave me an award! In my entire life, I have only ever received one award: in 2000，I was named Most Helpful by my university drama society.
This time, however, I won an actual award! Admittedly, there was no big awards ceremony. just an email and a social media post. But, nevertheless, it's given me a glow of pride. Somebody acknowledged my achievements!
The problem is that society seems to favor youth. There are a million '30 under 30'lists which I was never on, and yet it was only last year that the magazine Forbes launched its '50 over 50'list. But while I don't want to take those awards away from the kids, I know if someone had declared me an 'up-and-coming'anything at 30，I'd have been as terrified as I was delighted; so much to live up to. Now, however, I am grabbing that award and shouting: "At last, the recognition I deserve!"，because I know how much work I've put in, and I'm not about to let anyone lessen that.
If I was to list the advantages of getting older, then the ability to recognize my accomplishments and to be proud of them would be at the very top. Heard too many times, it's boring to say that we women put ourselves down, but too often we push away praise, rather than taking it up like the cat who got the cream. For most of us, praise is not a daily gift. So, when it comes, we need to allow ourselves to receive it. And if no one else is giving it to us, we need to give it to ourselves.
It works the other way, too. My new favourite hobby is writing emails to the head offices of restaurants and shops, to tell them how lovely their staff are. It makes me feel good, and I hope it does them, too.
A friend once told me about a self-development course she'd been on where participants had to shout 'I apprise of my decision!'，and then high-five themselves. I put this ritual into my daily life. Now, I am done. And, then, I'm writing myself an email of praise. Because, like that award, I deserve it.
Heat is the biggest end use for energy all over the world. It's also eritically important for survival in a country like Finland where the winter is long, cold and dark. And the recent move by Russia to cut off supplies of gas and electricity in response to Finland joining NATO has caused concern.
There is god news, however, that the world's fully first working sand battery has been installed in Finland. It is a device which can store sustainably produced heat for months at a time and can be used to keep homes warm in winter. That's why the new technology was developed by researchers there. Researchers believe it can solve the country's year-round crisis in power supply, which is a significant, issue for green energy.
The sand battery was installed in the Vatajankoski power plant that ruins the heating system for the houses in the area. It works by heating the sand, circulating the heat generated in the sand using a heat exchanger. Researchers used low -grade sand to charge the devices with heat from cheap electricity coming from either solar or wind energy. The sand battery can store energy and heat up to 500 degrees Celsius, which can be used to warm homes during winter when electricity is more expensive.
It is a cost-effective method because when the battery releases the hot air, it warms the water for the district heating system that is pumped around homes, offices, and the local swimming pool. Sand is an ideal material because it is cheap and readily available everywhere. While other inexpensive items like water can store heat, sand can be heated to much higher temperatures. The sand used is of the lowest quality so it cannot be used in construction thus making it a sustainable choice. Besides, sand-based batteries last longer than other batteries. According to a study, researchers obtained silicon using sand to create a battery that lasts three times longer than lithium-ion (锂离子) batteries.
"This innovation is a part of the smart and green energy transition. Heat storage systems can significantly help to increase intermittent (间歇性的) renewables in the electrical network, " said Markku Ylonen, co-founder of Polar Night Energy. "At the same time, we can make full use of the heat waste to keep the city warm.
The environmental practices of big businesses are shaped by a fundamental fact that offends our sense of justice. A business may maximize the amount of money it makes by damaging the environment and hurting people. When government regulation is effective, and the public is environmentally aware, environmentally clean big businesses may out-compete dirty ones, but the reverse is likely to be true if government regulation is ineffective and the public doesn't care.
It is easy to blame a business for helping itself by hurting other people. But blaming alone is unlikely to produce change. It ignores the fact that businesses are not charities but profit-making companies, and they are under obligation to maximize profits for shareholders by legal means.
Our blaming of businesses also ignores the ultimate responsibility of the public for creating the conditions that let a business profit through destructive environmental policies. In the long run, it is the public, either directly or through its politicians, that has the power to make such destructive policies unprofitable and illegal, and to make sustainable environmental policies profitable.
The public can do that by accusing businesses of harming them. The public may also make their opinion felt by choosing to buy sustainably harvested products; by preferring their governments to award valuable contracts to businesses with a good environmental track record; and by pressing their governments to pass and enforce laws and regulations requiring good environmental practices.
In turn, big businesses can exert powerful pressure on any suppliers that might ignore public or government pressure. For instance, after the US public became concerned about the spread of a disease, transmitted to humans through infected meat, the US government introduced rules demanding that the meat industry abandon practices associated with the risk of the disease spreading. But the meat packers refused to follow these, claiming that they would be too expensive to obey. However, when a fast-food company made the same demands after customer purchases of its hamburgers dropped, the meat industry followed immediately. The public's task is therefore to identify which links in the supply chain are sensitive to public pressure.
Some readers may be disappointed or outraged that I place the ultimate responsibility for business practices harming the public on the public itself. I also believe that the public must accept the necessity for higher prices for products to cover the added costs of sound environmental practices. My views may seem to ignore the belief that businesses should act in accordance with moral principles even if this leads to a reduction in their profits. But I think we have to recognize that, throughout human history, government regulation has arisen precisely because it was found that not only did moral principles need to be made explicit, they also needed to be enforced.
My conclusion is not a moralistic one about who is right or wrong, admirable or selfish. I believe that changes in public attitudes are essential for changes in businesses' environmental practices.
Online training is one of the fastest growing parts of the fitness industry. If you're considering joining the online fitness community, consider these benefits and drawbacks.
One of the most popular reasons for working out following an online video is that it offers ultimate convenience. No need to roll out of bed at 5 a. m. to attend that 6 a. m. boot camp class, which may end up being full when you arrive. And what if you're on the road? No problem. You can access your workout video through your phone.
Most online fitness programs are much less expensive than similar offline programs—most range in cost from ﹩ 10 to ﹩ 20 per month. Some are even free. For example, the online Les Mills+ program offers a free 30-day trial of its 1，500-plus workouts.
Online training also has broad offerings. When you head online, you have instructors from around the globe, all ready and willing to help you master your favorite moves. Just because there isn't a Krav Maga class in your area doesn't mean you can't go online to find one led by qualified instructors.
All these are undoubtedly positive-online training provides fitness resources to general consumers wherever they are, without requiring access to a gym or fitness studio. Very few online fitness programs enable the instructor to see you, check your form, and offer corrections based on your performance. This is particularly concerning for beginners, as they're more likely to do incorrectly. Besides, if you struggle with self-motivation and prefer a social workout environment, online fitness may not be for you.
A. Another is the price.
B. But it's not without problems.
C. The same goes for different types of exercise.
D. However, online personal training isn't for everyone.
E. Instead, you can turn it on at home at your convenience.
F. That being said, online workouts aren't perfect when it comes to safety.
G. This means you could perform exercises wrongly, or even unsafely, without knowing it.
TikTok, a social media app dedicated to short-form videos, has emerged as a major firer of food trends — from mushroom coffee and pancake cereal to cloud bread and feta pasta. But another trend, the #whatieatinaday trend, is dominating TikTok, which is nearing 9 billion 1.
Even though #whatieatinaday posts may be 2 to serve as healthy inspiration for others, there's a growing feeling that these video diaries of daily eats will likely do more harm than good — especially among young girls or people with a history of disordered eating.
The 3 message these posts send is that if you eat like them, then you can eventually look like them. Yet what someone else eats in a day doesn't mean it's right for you, since these "4" videos are not a completely accurate representation of what someone typically eats.
Often the overly stylized (程式化) meals do not 5 a nutritionally adequate diet. The posts are 6 the illusion (幻想) of an ideal day of eating, along with an ideal body size.
Younger audiences, especially girls and young women, internalize the message that they must eat like these creators to achieve and maintain not only health, but also social 7. The biggest harm with this trend is that it normalizes disordered or 8 eating behaviors. This could prevent someone struggling with an eating disorder from 9 support or treatment.
Even if the #whatieatinaday posts are displaying a 10 day of eating, the subtext message of "eat like me, and you will look like me" is harmful because people will not necessarily achieve the same body size as the 11 even if they copied their day of eating bite for bite.
12, what might be a healthy, adequate day of satisfying meals for one person may be inadequate and unsatisfying to another. Even worse, someone looking at these posts may conclude that they need to be eating half as much to 13.
People making these videos are overwhelmingly thin, young, able-bodied and white. There is a complete lack of body 14. And this encourages harmful comparisons to unrealistic body standards that are 15 to the vast majority of people. Therefore, those of us from marginalized communities are once again unable to see positive representations of our varying bodies, foods and cultural representation in these harmful posts."
With about half of the vast country covered in wilderness, China is the world's third most species-rich country. Therefore, China's (achieve) in biodiversity conservation and wilderness protection are important to the future of global biodiversity conservation.
The vital biodiversity, (combine) with a large population, has led the government to reconsider its protected area system and transform some wilderness areas such as the rainforest in Hainanformal national parks. The new national park system will make it more practicals(preserve) habitats and species. The aim is to preserve biodiversity and ensure a(harmony) relation between humans and nature.
The national parks cross China's vast ecosystems, from the Hainan Tropical Rainforest National Park in the souththe Hainan gibbon —a critically endangered species live, the Giant Panda National Park, the Northeast Tiger and Leopard National Park, the Wuyl Mountain National Park to the Sanjiangyuan National Park on the Qinghai- Tibet Platau —source of the Yellow River, the Yangtze River and the Lancang River. The diversity of species and habitats under protection(reflect) in these parks'names.
The national parks are open to all. Visitors can make reservations online in advancebook on the spot. They should acquire a little local knowledge to getready for the amazing trip and maximize their enjoyment.

Karl walked to the back of the classroom to put his book away. There, lying on the carpet in front of the bookcase, was a golden ticket! He picked it up. His heart beat faster when he saw that the name line was blank.
The boys and girls in Karl's class could earn golden tickets by doing well in their work or by being extra helpful or kind. Once a week his teacher, Miss Evans, drew a ticket out of a jar, and let the winner choose a prize. Karl couldn't believe his luck.
The golden ticket was going to be drawn, and here was another ticket, just for him. He looked around, but no one else was near the ticket. All his classmates were at their desks, laughing and talking with each other.
Karl decided to write his name on the blank line. Then he could put it into the prize jar with the tickets he'd already earned. With so many chances, at least one of his tickets would be picked! Then he could choose the pink pig as his sister's birthday present, just like what he had been hoping for.
He smiled and reached for the pencil in his pocket. Suddenly his fingers stopped. There was a strange feeling in his chest, and it wasn't his heartbeat.
He looked out of the window and tried to figure it out（弄明白）. He did find the ticket, but he hadn't earned it. Maybe whoever lost it was looking for it. But he needed this extra ticket for his great plan!
He remembered what Dad had told him and his sister. "When you make a right choice, you can feel peaceful inside. You never have to feel bad about your choice later. "
Paragraph 1：
He put the pencil back in his pocket.
Paragraph 2：
"Karl, I'd like you to have another ticket, " Miss Evans said.
