Secrets of Web Travel Sites

Booking a trip on an online travel siteis convenient, but comes with its own set of problems.

1 They who's on a Mac and who's on a PCand who's going to spend more.

Last year, US travel research companyOrbitz tracked people's online activities to test out whether Mac users spendmore on travel than PC users. On average, Mac users lay out US$20-30 more pernight on hotels and go for more stars. according to the Wall Street Journal. Asa result, online• travel sites show these users more expensive travel optionsfirst. To avoid inadvertently paying more, sort results by price.

 Their software doesn't always hook up to thehotel's system.

A guaranteed reservation is almostimpossible to come by anywhere — but the risk of your flight or hotel beingoverbooked increases with third-party providers. The middle-man's softwareisn't immune to system errors, so always call the hotel or airline to make sureyour booking was processed.

 Don't be fooled by packages: Often, they'relow-end items grouped together.

Ever notice how travel sites recommend ahotel, a rental car, and tour package all in one click? These deals usuallyfeature travel that no one wants, like flights with multiple layovers.

Check the fine print.

 You could miss out on loyalty points.

Third-party providers can get betweenyou and frequent flyer miles or points. Many hotel loyalty programmes don'trecognise external sites, others award only minimum points and exclude specialoffers, like double points on hotel stays.

 Once your trip is purchased, you're on yourown.

An online travel agency can't provideassistance the same way an agent can if a flight is cancelled or a room issubstandard. Basically, when you arrive at the airport or hotel, you're justanother client who booked at the lowest rate.

    A minister was on a long flight from China to London. The first warning of the approaching problems came when the sign on the airplane flashed on: Fasten your seat belts. Then, after a while, a calm voice said, "We shall not be serving the drinks at this time as there is going to be something unexpected. Please be sure seat belt is fastened."

    Soon the storm broke out. One moment the airplane was lifted on terrific currents of air. The plane dropped as if it were about to crash.

    The minister believed that he shared the discomfort and fear of those around him. As he looked around the plane, he could see that nearly all the passengers were upset and alarmed. The future seemed ominous and many were wondering if they would make it through the storm. Then he suddenly saw a little girl. Apparently the storm meant nothing to her. She was reading a book and everything within her small world was calm orderly. Sometimes she closed her eyes and then she would read again. Then she would straighten her legs, worry and fear were not in her world. The minister could hardly believe his eyes.

    It was not surprising therefore that when the plane finally reached its destination and all the passengers hurried to leave, the minister walked up to the girl he had watched for such a long time. Having commented about the storm and the behavior of the plane, he asked why she had not been afraid. The girl replied, "Because my dad is the pilot, and he's taking me home."

    A characteristic of American culture that has become almost a tradition is to respect the self-made man--the man who has risen to the top through his own efforts, usually beginning by working with his hands. While the leader in business or industry or the college professor occupies a higher social position and commands greater respect in the community than the common laborer or even the skilled factory worker, he may take pains to point out that his father started life in America as a farmer or laborer of some sort.

    This attitude toward manual (体力的) labor is now still seen in many aspects of American life. One is invited to dinner at a home that is not only comfortably but even luxuriously (豪华地) furnished and in which there is every evidence of the fact that the family has been able to afford foreign travel, expensive hobbies, and college education for the children; yet the hostess probably will cook the dinner herself, will serve it herself and will wash dishes afterward, furthermore the dinner will not consist merely of something quickly and easily assembled from contents of various cans and a cake or a pie bought at the near- by bakery. On the contrary, the hostess usually takes pride in careful preparation of special dishes. A professional man may talk about washing the car, digging in his flowerbeds, painting the house. His wife may even help with these things, just as he often helps her with the dishwashing. The son who is away at college may wait on table and wash dishes for his living, or during the summer he may work with a construction gang on a highway in order to pay for his education.

    Stained glass (彩色玻璃) artists create different designs by making cuts on the glass to “score” it and then breaking off the pattern that they want to use in the finished product. The most difficult cut in stained glass is called an inside cut. Basically, it's a curved (弯曲的) line where you throw away the part inside of the curve. The problem with inside cuts is that the edges of the curve tend to break off when the pieces of scored glass are broken apart.

    As the artist talked about inside cuts, he said, “The glass will break into pieces if you try to cut too much off at once. The best way to do an inside cut is to slice off smaller curves piece-by-piece. In fact, it's not just the best way to do it, but it's the only way to do it.”

    How many times do you try to make a big change and cut the entire piece at once? We convince ourselves that we can do this all the time. We'll commit to transforming our diet overnight or we get inspired to launch a business in a weekend or we finally get motivated to work out and push ourselves to the edge of burning out.

    Why not approach your goals and dreams like a stained glass artist? Starting by slicing a shallow curve and breaking a small piece off, you cut a slightly deeper curve and break that off until you have your full inside cut. By slowly cutting deeper and deeper curves, you prevent the glass from breaking as it changes shape.

    Of course, change isn't easy — no matter how you do it. Slow gains are boring, but if we keep making small improvements, then pretty soon we will end up with a beautiful masterpiece on our hands instead of a bunch of broken pieces.

    The world's insects are going down the path of extinction, threatening a "catastrophic collapse of nature's ecosystems", according to the first global scientific review. More than 40％of insect species are declining and third are endangered, the analysis found. The rate of extinction is eight times faster than that of mammals, birds and reptiles.

    "It should be of huge concern to all of us, for insects are at the heart of every food web. They pollinate (授粉) the large majority of plant species, keep the soil healthy, recycle nutrients, control pests, and much more. Love them or 1oathe them, we humans cannot survive without insects, "said Prof Dave Goulson at the University of Sussex in the UK.

    The analysis, published in the journal Biological Conservation, says intensive (集约型) agriculture is the main driver of the declines, particularly the heavy use of pesticides. Urbanisation and climate change are also significant factors.

    "If insect species losses cannot be stopped, this will have catastrophic consequences for both the planet's ecosystems and for the survival of mankind. It is very rapid. In 10 years you will have a quarter less, in 50 years only half left and in 100 years you will have none," said review author Francisco Sánchez-Bayo, at the University of Sydney, Australia.

    One of the biggest impacts of insect loss is on many birds, reptiles, amphibians and fish that eat insects. "If this food source is taken away, all these animals starve to death," he said. Such effects have already been seen in Puerto Rico, where a recent study revealed a 98％fall in ground insects over 35 years.

    Matt Shardlow, at the conservation charity Buglife, said: "It is thoughtful to see this evidence that shows the pitiful state of the world's insect populations. It is increasingly obvious that the planet's ecology is breaking and there is a need for a strong and global effort to prevent and change these terrible trends."

A new study estimates more than 1 billion people worldwide are currently living with obesity. People with obesity are considered medically overweight. The study, published in the medical publication The Lancet, said that one in eight people are obese. Researchers said around 43 percent of adults were overweight in 2022. Obesity among adults has more than doubled since 1990. Among young people aged 5 to 19, the obesity rate increased by four times during the same period.

"A staggering number of people are living with obesity, and severe obesity is strongly linked to a long list of health problems and an early death." declared the lead writer of the study, Majid Ezzati, a professor at Imperial College London.

The WHO noted that at the World Health Assembly in 2022, member states agreed to an agency plan to fight obesity. So far, 31 governments "are now leading the way" to reduce obesity by carrying out goals of the plan.

These include government measures to enact new rules on "harmful" marketing of unhealthy food and drinks to children. In addition, governments are aiming to improve school and nutrition policies. They are also seeking price reductions for healthy foods, to increase public awareness about healthy diets and exercise and to strengthen requirements for physical activity in schools.

Imperial College's Ezzati said that obesity rates are not rising in many wealthier nations. But they are quickly increasing in other countries. He noted that some countries have many underweight people, meaning the nations are facing what he called a "double burden" of nutrition problems.

Branca is head of nutrition at the WHO. He told reporters, "In the past, we have been thinking of obesity as a problem of the rich, but obesity is a problem of the world. Although new obesity drugs — such as Ozempic and Wegovy — could be helpful tools in reducing obesity, they noted that the cost and availability of the drugs might increase inequality."
