With fuel costs rising and airlines finding more fees to impose on travelers every day, airfare isn't getting any cheaper. Since you can't drive to all your dream destinations, flying is the only way to go sometimes and, undeniably, the fastest. Luckily, there are plenty of ways to find the most affordable fares and also avoid paying as many extra charges as possible when you plan ahead.

    Getting the best fare. Airlines put out their fare sales on Tuesday morning, making this day the best day to book a flight for less.

    Fly during the least popular times. Tuesday, Wednesday and Saturday are the slowest days to fly, which means cheaper deals than the rest of the week. You can also find reduced rates on early morning flights, since many people don't like to get up before the sun to get to the airport. Earlier boarding times can also considerably cut down your chances of getting bumped on an overbooked flight or delayed because of other delayed flights or mechanical issues.

    Choose your seat later. Some airlines charge you to pick your seat when you book online, adding even more to the bottom line of your ticket cost. If you show up early on your travel day, you can still get suitable seats. Some of the best seats get held back until flight day, unless others are willing to pay extra for them ahead of time, so you still have the chance at one of those.

    Fly on holidays. You already know that summer is the most expensive time to fly, and even though most other times are more affordable, the days surrounding holidays can be crazy. Save big if you're willing to travel on major holidays, such as Thanksgiving and Christmas.

    Don't wait until the last-minute to book. Many travelers don't know that there's a sweet spot for booking and getting the best price on your tickets. Book too early or too late and you could end up paying more than you need to. The best time to book is between three months and six weeks from when you want to travel.

    Avoiding extra fees Airlines will charge for just about anything these days. Some have even toyed around with charging customers for using the restroom. All those extra fees can certainly add up, but there's no reason to pay them if you don't have to. Here are some tips to keep money in your wallet once you get to the airport.

    Avoid the upgrade it's not necessary. Sometimes upgrades are free, but mostly you will be charged for seeking a last-minute bump to first class, and the cost can be hefty.

    Fly carry-on only. Baggage fees vary wildly, but almost all airlines charge them and charge big. Why pay for your clothes to fly with you? If everyone in your travel party checks a bag, your bill can be astronomical before you ever even get to your destination. It's easy to reduce the amount of stuff you pack: Make sure all your clothing coordinates, so you can take less and still make more outfit combinations, take only two pair of shoes, plan to do a bit of laundry on your trip and bring only travel-sized toiletries.

    Pack your own snacks. Unless you're flying internationally, it's rare your flight comes with a free meal. Snacks on the plane are not cheap and almost never healthy. Don't rely on what's on the small menu and instead tuck some of your own snacks — granola bars, homemade muffins, fruit and trail mix all make fantastic travel foods — into your bag and eat a lot better, and cheaper, than other passengers.

    While money can't technically buy happiness, it can buy you a mood-lifting, outlook-improving vacation. Haven't made plan yet to skip town this winter? These money-saving travel tips can help you book the destination of your choice and enjoy you time there—without breaking the bank.

    1).FLY THE COOP FAST

    If you're planning to set off for an adventure right away, try the GTFO(Get The Flight Out) app. It lists the cheapest round-trip flights departing from your local airport that day or by the next morning. At press time, airfare was down 12 percent from last August and round-trip tickets for domestic flights averaged $218.

    2).SNAG A DISCOUNTED HOTEL ROOM

    If Airbnb, an online service that provide apartment exchange, isn't your style, reserve marked-down accommodations on Tingo, which lists almost all the rooms in more than 155,000 locations worldwide. After you book a price drop room, the site monitors rates until, typically, 24 to 48 hours before check-in. If the price drops, Tingo refunds you the difference.

    3).LIVE IT UP LOCALLY

    If you're planning a staycation(宅度假) this winter, try an affordable escape close to home. The free app HotelTonight offers lodging(租住) deals in more than 100 U.S. and Canadian cities and regions, and has a location-based feature that gives extea saving on already discounted prices on spots closest to you. Same-day prices fall even lower after 6 P.M.

    Since the first Earth Day in 1970, Americans have gotten a lot “greener” toward the environment. “We didn't know at that time there even was an environment, let alone that there was a problem with it,” says Bruce Anderson, president of Earth Day USA.

    But what began as nothing important in public affairs has grown into a social movement .Business people, political leaders, university professors, and especially millions of grass-roots Americans are taking part in the movement. “The understanding has increased many， many times,” says Gaylord Nelson, the former governor from Wisconsin, who thought up the first. According to US government reports, emissions (排放)from cars and trucks have dropped from 10.3 million tons a year to 5.5 tons .The number of cities producing CO beyond the standard has been reduced from 40 to 9. Although serious problems still remain and need to be dealt with, the world is a safer and healthier place. A kind of “Green thinking” has become part of practices.

    Great improvement has been achieved. In 1988 there were only 600 recycling programs; today in 1995 there are about 6,600. Advanced lights, motors, and building designs have helped save a lot of energy and therefore prevented pollution.

    Twenty –five years ago, there were hardly any education programs for environment. Today, it's hard to find a public school, university, or law school that does not have such a kind of program. “Until we do that, nothing else will change!” say Bruce Anderson.

The next time you attend a social function or go to a place where people meet and interact, take note of the number of people who have adopted the same gestures and posture—the way you sit or stand--of the person with whom they are talking. This "carbon copying" is a means by which one person tells the other that he is in agreement with his ideas and attitudes. By this method, one is non-verbally (非语言的) saying to the other, "As you can see, I think the same as you, so I will copy your posture and gesture."

    This unconscious (无意识地) mimicry is quite interesting to observe. Take, for example, the two men standing at the hotel bar. They have mirrored each other's gestures and it is reasonable to assume that they are discussing a topic upon which they have the same thoughts and feelings. If one man uncrosses his arms and legs or stands on the other foot, the other will follow. If one puts his hand in his pocket the other will copy and this mimicry will continue for as long as the two men are in agreement.

    This copying also occurs among good friends or people of the same social position and it is common to see married couples walk, stand, sit and move in very similar ways. People who are strangers, however, try hard to avoid holding mutual(相互的) positions. The significance of carbon copying can be one of the most important non-verbal lessons we can learn, for this is one way that others tell us that they agree with us or like us. It is also a way for us to tell others that we like them, by simply copying their gestures.

    If an employer wishes to develop immediate friendliness and create a relaxing atmosphere with an employee, he needs to copy the employee's posture to achieve the end. Similarly, an up-and-coming employee may be seen copying his boss's gestures in an attempt to show agreement. Using the knowledge, it is possible to influence a face-to-face encounter by copying the positive gestures and postures of the other person. This has the effect of putting the other person in a receptive and relaxed frame of mind and he can "see" that you understand his point of view.

    A new study has found the amount of antibiotics(抗生素)given to farm animals is expected to increase by two-thirds over the next 15 years. Researchers are linking the growing dependence on the drugs to the increasing need for meat, milk and eggs. However, the drugs could quicken the development of antibiotic-resistant infections(感染). Such infections are already a major public, health concern in the United States.

    The World Health Organization notes when people stop living in poverty(贫困), the first thing they want to do is eat better, rather than earn more money. For most people, that means their diet should contain more meat. With the rapid development of Asia, people there are eating nearly four times as much meat, milk and other milk products as they did 50 year ago.

    To meet the need, farmers have put many animals into smaller spaces. As the animals are crowded together, the easiest way to deal with some of the problems of crowding is to give them antibiotics. It's clear that antibiotics help animals stay healthy in a crowded environment and grow faster. But bacteria can develop resistance to the drugs gradually.

    Nowadays, doctors find antibiotics that once worked against the infections no longer work. The bacteria have learned ways to fight against the drugs. The heavy use of antibiotics in animals is responsible for the growth of antibiotic resistance worldwide. In the United States, at least two million people get drug-resistant infections each year and at least 23,000 die from an infection.

    Europe has banned the use of antibiotics to increase animal growth. And the United States is hoping to persuade farmers to stop using antibiotics for that purpose.

    Debby Harris says she would never have started going to the Glastonbury Festival if her friend who runs a food stand hadn't needed a hand a few years ago. "I thought it would just be all noise, and I never liked rock music.^" Now she says she would pay her friend to allow her to work at her stand!^" The tickets sell like hot cakes, so it's the best way of making sure I can get to the five-day festival in June." she points out.

    Nick Hendon likes going to the Cambridge Folk Festival, which takes place over a long weekend in summer at Cherry Hinton Hall. His favourite festival area is the Club Tent where members of the audience, as well as the invited artists, can get up and perform. "My wife usually takes part. She has a beautiful voice," he says proudly.

    Joan Mitchell does her best to get to the International Eisteddfod, a dance and music festival which takes place every year during the second week of July in Wales. The festival is also famous for the final Sunday Evening Gala concert which usually has some of the biggest names in opera as guest performers.

    ^“I've seen Dame Kiri Te Kanawa, James Galway and Montserrat Caballe, but no one could ever match Luciano Pavarotti. He was truly breathtaking!''

    Graham Crosby tries to get to as many concerts as possible during the eight-week summer season of the Proms festival every year. The Proms is the largest classical music festival in the world." The atmosphere (氛围)is much more relaxing than that at other classical concerts. In fact, the audience sometimes behave more like rock fans, jumping up and down to the music, which is really exciting."
