A survey has shown that what you do on a plane can be determined by which nationality is listed on your passport.

    According to the results of an international passenger survey, Australians are the biggest drinkers on board with 36 percent choosing to down the hatch, compared to 35 percent of Americans and 33 percent of Brits.

    The Airline Passenger Experience Association(APEX) spoke to around 1,500 people, aged 18 and older, who have traveled by plane at least once during the last three months and were living in the United States, United Kingdom, Germany, Japan, China, Singapore, Australia and Brazil.

The results found Chinese travelers are most likely to nod off once the seat-belt sign switches off. They are also the first to take out their credit card for some in-flight shopping and the biggest fans of gaming. Americans on the other hand like to use their time in the air more productively—- when not drinking—- choosing to work while flying at 35,000 feet.

Meanwhile, Brits and Germans are the best at making chat with random strangers—-spending 50 percent more time than any other nationality. Comparatively, Brazilians conduct their conversations online via email, messaging apps or social media.

    Despite plane food having a bad reputation, seven out of ten interviewees said they were happy to eat up on the selection of in-flight snacks and meals. In-flight magazines were also popular with four out of five passengers.

    The international flyers did however express their desire for better in-flight entertainment. “The industry has greatly improved the comfort, entertainment and onboard service, and passengers are accepting those improvements” said Russell Lemieux, APEX executive director. “At the same time, passengers are demanding more from their air travel experiences which will drive more improvements touching all aspects of the journey.” he added.

    Work started this week on next season's flu vaccine (疫苗), with experts working off forecasts about which types of the flu virus will be making the rounds. But don't expect any improvements. Flu experts are already admitting that most vaccines will give at best basic protection, because they're based on old-fashioned technology. It's not a new problem, but one that the slow-moving world of drug and vaccine production seems helpless to improve upon.

    Every flu vaccine is a cocktail, aimed at either three or four of the most common flu types. Flu vaccines must be recreated every year because flu viruses develop constantly in a process called antigenic drift. In February, global flu experts gather to trade notes on what viruses are circulating in different countries and to come to an agreement on which types the next vaccines should be made to target.

    In recent years, flu vaccines have been based on H1N1, H3N2 and either one or two types of influenza B virus. Each of these has a "reference" type, which is used to make seed virus. Producers add the seed types to eggs and incubate (孵) them as the virus grows. Then they purify the virus, and either weaken it or kill it to make a vaccine.

    Using eggs is a tricky (=difficult) and unpredictable process. Sometimes the virus doesn't grow well in eggs, which can mean less vaccine than expected. The result is a flu vaccine that doesn't offer much protection. "As long as we have eggs we are going to have this problem," said Scott Hensley, a flu virus expert, "The only solution is not to depend on eggs."

    Flu is a major killer. The 2017-2018 season has been a severe one, hitting the entire U. S. with widespread influenza infection (感染) at once for weeks on end, and killing 97 children so far. Against this threat, even a less satisfying flu vaccine will definitely help. "Even when you have these mismatches it will not prevent infection but likely prevent disease severity," said Hensley.

    Bill Bowerman was a track coach. He wanted to help athletes run faster. So he had learned how to make running shoes. He had also started a shoe company with a friend. It was 1971. Running shoes at the time were heavy. They had spikes (鞋钉) on the sole (鞋底). The spikes tore up the track and slowed down runners.

    To make a lighter shoe, Bill tried the skins of fish. To make a better sole, he wanted to replace the spikes. Bill dug through his wife Barbara's jewelry box. He hoped to find a piece of jewelry with an interesting pattern. He would then copy the pattern onto the new soles. Nothing worked. Bill was defeated.

    Then, one Sunday morning, Barbara made Bill waffles (华夫饼) for breakfast. Bill watched her cook.

    He studied the criss-cross pattern on a waffle iron.

    Inspiration struck. The pattern on the waffle iron was just what Bill was looking for. The squares were flatter and wider than sharp spikes. The pattern would help the shoes hold any surface without tearing into it.

When Barbara left the house, Bill ran to his lab. He took the liquid chemicals that, when mixed, would harden into the sole of a shoe. He poured the mixture into the waffle iron—and the Waffle Trainer was born.

Bill's company put the Waffle Trainer on market in 1974. It was a huge hit. Maybe you've heard of that company—it's called Nike. And today it's worth around $100 billion.

It was the waffle iron that had changed the course of Bill's life—and helped turn Nike into a well-known name. Today, the waffle iron is kept at Nike headquarters. It serves as a reminder that if we keep trying, we can find a solution to even the most difficult problems. And those solutions can come from unlikely places, even the breakfast table.

    Japanese researchers made a botanical announcement on Monday that quickly circled the world. They had developed a banana with an eatable peel (皮)—the Mongee banana.

    The technique used by scientists at D&T Farm is called "freeze thaw awakening". The process involves starling banana trees out in an environment that's nearly minus-80 degrees Fahrenheit, then moving the trees with their still-ripening bananas to a climate of around 80 degrees - an environment banana trees typically grow in the entire time. The extreme temperature change puts the banana's growth into a superfast-speed mode. In this case, the fruit ripens before the skin can catch up. The result is soft and thin skin that hasn't fully developed.

    The banana has been produced only in small amount so far, so customers face a steep bill to save themselves the bother of peeling their banana: it is currently priced at 648 yen ($6) a piece. There's also the question of whether a banana peel is actually worth eating and whether regular banana peels had, rather suddenly, become too big a problem for people who slip on them to bear anymore.

    And what about shipping? For most of the fruit's history, the peel has provided protection, allowing it to travel long distances from where it's grown to nearly every country on Earth. A softer banana would be a step back from regular banana varieties that travel thousands of miles.

    But the banana in the news is arguably good, particularly for a fruit that rarely receives its share of attention. Bananas are the most  consumed fruit in Japan, and also in the U.S. So even if eatable-peel bananas don't ensure plentiful bananas, or even necessarily nutritious bananas, they still look great on Instagram, which probably ensures them a future in Japan's famous luxury (奢侈) fruit markets.

    The weather affects many aspects of people's daily life. Knowing and understanding what the weather is doing is useful.

    However, the weather is also one of the most unpredictable elements in the world. Although many people watch the morning news and gather the information about the weather, this is often wrong. Whole days can be ruined by believing that the weather will be one thing, when it turns out to be another. However, owning wireless weather stations allows the owners to monitor the weather for themselves.

    Not only will these weather stations allow the owners to see what the weather is doing, but it is personalized(个性化)to them and their area. Wireless weather, stations are specifically prepared for the immediate neighborhood. Plans will be able to be made, and important decisions will no longer be ruined by bad weather.

    Although these weather stations are typically seen in homes, they can also be used very easily on farms and fishing boats. Both farmers and fishermen rely on the weather for their business and using up-to-date weather information is quite indispensable. By using the wireless weather stations, it can determine for them when to harvest crops and head back to the shore. Because of the size of the weather station, they can be moved very easily and used wherever necessary for people.

    The wireless weather stations are great for all homes, especially for areas that suffer from extreme weather conditions. The up-to-date, instant weather reports will allow a person to monitor what the weather is doing and if the bad weather is heading in their direction. Extreme weather tends to come very quickly; therefore, any information that is received is helpful.

    The weather stations are very simple to set up and are run by solar panels(太阳能板), ensuring they will work even if there is a power-cut. They are far smaller than those in previous years and give a couple of very simple read-outs for the owner. They are easy to use and fascinating to understand.

There are two types of people in the world. Although they have equal degree of health and wealth and other comforts of life, one becomes happy and the other becomes unhappy. This arises from the different ways in which they consider things, people, events and the resulting effects.

    People who are to be happy fix their attention on the convenience of things: the pleasant parts of conversation, the well-prepared dishes, the goodness of the wine and the fine weather. They enjoy all the cheerful things. Those who are to be unhappy think and speak only of the opposite things. Therefore, they are continually dissatisfied. By their remarks, they sour the pleasure of society, hurt many people, and make themselves disagreeable everywhere. If this turn of mind was founded in nature, such unhappy people would be more pitiful. The intention of criticising and being disliked is perhaps taken up by imitation. It grows into a habit, unknown to its possessors. The habit may be strong, but it may be cured when those who have it realise its bad effects on their interests and tastes. I hope this little warning may be of service to them, and help them change this habit.

    Although in fact it is chiefly an act of imagination, it has serious results in life since it brings on deep sorrow and bad luck. Those people hurt many others; nobody loves them, and no one treats them with more than the most common politeness and respect. This frequently puts them in a bad temper and draws them into arguments. If they aim at getting some advantages in social position or fortune, nobody wishes them success. Nor will anyone start a step or speak a word to favour their hopes. If they bring public objections to themselves, no one will defend or excuse them, and many will join in to criticise their wrongdoings. They should change this bad habit and be pleased with what is pleasing, without worrying needlessly about themselves and others. If they do not, it will be good for others to avoid any contact with them. Otherwise, it can be disagreeable and sometimes very inconvenient, especially when one becomes mixed up in their quarrels.
