2 . There’s just a 1 in 3, 700, 000 chance that a person will be killed by a shark in their lifetime, but the fear is still enough to have swimmers worrying about being perceived as prey (猎物). Now, new research supports the long-standing theory that when great whites do go in for a bite, it’s a case of “mistaken identity”.

A team of biologists from the UK and Australia compared videos of seals swimming with videos of humans swimming. They then edited the videos to simulate (模拟) a great white’s vision — the sharks are likely colorblind, and they can’t make out fine detail-and found that from the point of view of the ocean creatures, humans do indeed bear a strong resemblance to seals.

“Great white sharks are often regarded as ‘mindless killers’ and ‘fond of human flesh’. However, that's not the case — we just look like their food,” Laura Ryan, lead author of the study, said.

Despite their dissatisfying vision and spatial perception, great white sharks are highly visual creatures, and rely on motion and shadows when on the lookout for prey. To really see through the species’s eyes, the research team had to get creative.

“We attached a camera to an underwater scooter (轻便小车), and set it to travel at a typical speed for predatory sharks,” Ryan said in a statement. The researchers then paired the recordings with computer models to simulate how similar people look from a shark's view below the surface.

“I knew there would be some similarities, but not to the extent we have found,” Ryan said. “Specifically, I thought swimmers might not be as similar as surfers to seals as they typically aren’t involved in as many shark bites. However, the swimmers are also difficult to tell apart from seals.”

Ryan put it in a statement, “Understanding why shark bites occur can help us find ways to prevent them, while keeping both humans and sharks safer.”

3 . People who possess high self-esteem are able to commit better and produce a greater bond in relationships with others. Dr. Douglas feels that most people do not value themselves, but with love and self-respect anyone can be above normality and grasp success with the family, the office, or others.

We have become too reliant on intelligence, beauty, and money for our own self-esteem. The loss of esteem reduces the will and ability to set and reach goals. In a series of readings Douglas teaches how to avoid negative statements, how to change them into self-facing behavior, and how to take charge of your mental attitude. Where other motivational and self-help works stop with the theoretical plan for success, Douglas takes everyday examples and puts them into his books. From raising children who believe in themselves to using self-esteem to help bridge the gap in the workplace, he gives readers concrete solutions to the problems that might ruin their interpersonal relations.

Self-esteem building comes from filling your thoughts with positive affirmations (肯定) and learning to react to failures with motivation instead of self-destruction. These lessons are valuable for anyone who feels that life is even slightly out of control. People who feel they have adequate esteem can learn to use it to make their success grander, faster, and more beneficial for others. Douglas approaches this process of self-development as a means of more than creating good things for the individual but also for setting up keys for influencing good things for others.

For more than thirty years, Dr. Douglas has addressed more than two million people on topics from time management to speaking effectively to raising drug-free children. He is the author of fifteen books, including How to Make a Habit of Succeeding.

The “24 solar terms” are a vital part of the Chinese calendar, which has     1     (it) origin with the ancient Yellow River basin. The Chinese calendar     2     (include) “24 solar terms”provides detailed guidelines and timetable for agricultural     3     (activity).

A complete set of “24 solar terms” first     4     (appear) in an ancient book The Huainanzi in early Han Dynasty. These 24 solar terms were soon absorbed into The Taichu calendar, the first well documented calendar in     5     history of China.

The Chinese Agriculture Calendar is     6     (actual) a combination of the lunar and solar calendar systems. There     7     (be) 365. 2422 days in one “sidereal year” while 12 lunar months add up to 354 days. To make both the lunar calendar     8     the solar calendar agree, a leap lunar month needs to be added every 2 to 3 years. Since the early Han Dynasty, a lunar month without a major solar term     9     (adopt) as a leap month (闰月) .

With more far-reaching cultural exchanges, the “24 solar terms” have been known     10     people in other parts of the world and were added to the “UNESCO World Intangible Cultural Heritage” list in 2016.

5 . Climate breakdown threatens to cause a global food production crisis. The UN forecasts that by 2050, feeding the world will require a 20% expansion in global water use for agriculture. It is hard to see how agriculture can feed the population of the planet, let alone toward the end of the century and beyond. Agriculture is a major cause of climate breakdown, and both river and air pollution. Industrial fishing is similarly driving ecological collapse in seas around the world.

However, at this critical time, farming (a new kind of food technology) is creating astonishing possibilities to save both people and the planet. Farming will enable the return of vast areas of land and sea to nature, greatly reducing carbon emissions (排放物). It means an end to the employment of animals, a stop to overfishing, and a dramatic reduction in cutting down forests and the use of pesticides (杀虫剂). It is the best hope for stopping the destruction of the planet and, if it is done right, it means cheap and abundant food for everyone.

We are about to welcome one of the biggest economic transformations, of any kind, for 200 years. Arguments continue about plants against meat-based diets; however, new technologies will soon make these arguments irrelevant. Before long, most food will come neither from animals nor plants, but from micro-organisms (微生物).

Not only will food be cheaper, it will also be healthier. Due to the fact that farming creates food products built up from simple components rather than broken down from complex ones, hard fats and other unhealthy components can be screened out. Meat will still be meat, but it will be grown in factories rather than in the bodies of animals. Fats will still be fats, but food is likely to be better, cheaper and much less damaging to the living planet.

6 . There are three things you can watch forever: Instagram feeds, YouTube videos and water. Among them, water is definitely something no one argues about, and there are many unusual water attractions that you can find around the world.

Bangkok Floating Markets

There are many floating markets where goods are sold from boats. While modern markets are more popular, floating markets still are a huge attraction for local tourism. Any visitors can purchase local foods and traditional handcrafted (手工的) souvenirs. Bargaining is a part of experience. So, start low and get the price you are ready to pay.

Bregenzer Festspiele

The Bregenz Festival is held every year from July to August in Vorarlberg. It has the world’s largest stage on the water. The performances are different every year but they are usually united by one theme. The decorations are very impressive and are worth seeing.

Marina Bay Stadium

This stadium was built as a temporary solution while Singapore National Stadium was rebuilt. The stadium was used for the opening and closing ceremonies during 2010 Summer Youth Olympics. It was a floating platform where the Formula One Grand Prix event was successfully held.

Archipelago Cinema

Archipelago Cinema is probably one of the world’s most scenic open-air cinemas that floats in the middle of a lake. The cinema was designed by German architect Ole Scheeren, who built it using techniques popular among local people. This cinema stage was built specially for the film festival Film on the Rocks Yao Noi.

10 . The world has spent a long time living with the pandemic. But many people have become lazy about protecting their safety. Are you spending time indoors and unmasked with trusted friends? Or eating in restaurants or making more trips to the grocery store? New types of COVID-19 mean you should try to cut back on exposure. And where you can, double down on basic safety.     1    .     .

Wear masks

The N95 mask is the gold standard. It may cost too much or be hard to find. A cloth mask does a good job of filtering particles that cause infection.     2     — two cloth layers with a filter in the middle. Double masking is the best answer when you find yourself around strangers. The KF94 mask is a good bet.

    3    

If you go to the store two or three times a week, cut back to once a week. If you have been spending 30 to 45 minutes in the grocery store, cut down your time in the store.     4    . If you are waiting in line, be mindful of staying at least six feet apart from the people ahead and behind you. Try using delivery services or curbside pickup.

Spend less time indoors with people who are not from your household. If you must spend time with others, wear your best mask. Be sure any space is well ventilated (通风)(open windows and doors). Keep the visit as short as possible.     5    

The coronavirus vaccine may or may not be the solution. As of now, you are the best answer. Take care. Do not let your guard down!
