Disney World is a very popular attraction. But going there can be costly. Here are some suggestions that can help you save money.

    Instead of eating at the park, get premade food from a nearby grocery store or even make your own lunch. Also, make sure to take your own water with you because spending $3 on water will make your stomach hurt. Another idea is to pack snacks or quick and cheap pick-me-ups as you make your way around the park.

    Of course you're going to want to take some Disney souvenirs home with you, but you'll quickly realize that it comes with a price. Before buying anything, make sure you have a plan. Some suggestions for keeping costs down include picking your own pearl at the Japan store at Epcot, which is all about the experience and only $15.95 plus tax, or even getting special tradable collection pin that you can trade with Disney cast members or other guests.

    When you go to Disney World on rainy days, you may catch a lot of showers. But you don't have to. Go to a local Dollar Tree and buy disposable ponchos（一次性雨披）for $1. The ponchos at Disney are probably more durable（耐用的）, but they cost $9. For a family of five, the Disney ponchos would cost $45 versus spending $5 at the dollar store.

    It costs $17 to park in Disney for a day. Luckily, most non-Disney resorts offer free shuttles（来往的班车）to and from the park and all Disney resorts offer free transportation for guests as well. If you like to be on your own schedule without worrying about when the shuttle comes, then parking is your only choice. But waiting for the shuttle and going by a schedule isn't really difficult, either.

    Experts say moods are feelings that tend to become fixed, influencing one's outlook for hours, days or even weeks. That's great if your mood is a pleasant one, but a problem if you are sad, anxious, angry or simply lonely.

    Perhaps the best way to deal with such moods is to talk them out; sometimes, though, there is no one to listen. Modern pharmacology（药理学）offers a lot of tranquilizers（镇静剂）. What many people don't realize, however, is that scientists have discovered the effectiveness of several non – drug methods to set you loose from an unwanted mood. These can be just as useful as drugs, and have the added benefit of being nonpoisonous. So next time you feel out of sorts, don't head for the drug – store but try the following methods.

    Of all the mood – altering self – help techniques, aerobic exercise（有氧运动）seems to be the most efficient cure for a bad mood. "If you could keep up the exercise you'd be in high spirits," says Kathryn Lance, author of Running for Health and Beauty.

    Researchers have explained biochemical and various other changes that make exercise compare favorable to drugs as a mood raiser. Physical work such as housework, however, does little. The key is aerobic exercise —running, cycling, walking, swimming or other repetitive and sustained activities that increase the heart rate, increase blood circulation and improve the body's use of oxygen. Do some of the activities for at least 20 minutes a session three to five times a week.

    Envelope Budget

    From McDonald's to Sonic, fast food had a bad effect on my waistline and my budget. It was nothing to run to a drive-through to pick up a cold drink or a quick bite to eat. It was so easy to use my card for a small purchase. For me, I got a lot of satisfaction from fast food.

    One day I sat down and calculated that I was spending a surprising $40 a week on fast food. This was a lot of iced coffee and hamburgers! Instead of reducing my guilty pleasures, I decided to give myself a strong budget to reduce my consumption. Every Monday I placed an envelope with $20 in my purse. That was my fast food budget for the entire week. If there was anything left over at the end of the week, it was mine to save or spend. If I spent all of the money during the week, there were no more fast food stops that week.

    The budget made me more mindful of my purchases. Instead of purchasing a large drink from Sonic, I would purchase a small. It was sill satisfying but not nearly as pricey. Instead of eating a whole meal, I would pick the part that I actually wanted. Many days, the thought of hanging onto the money for a special purpose meant more to me than the instant satisfaction of fast food. I never really felt unhappy because it was a conscious choice to spend or save with each purchase.

    Envelope budget kept me honest. I had a clear idea how much money was spent each week on fast food purchases. I started to bring my lunches more often to save more money for the week. It was a fun challenge to see how much I could save every week.

    Changing the way I spent on fast food not only helped my budget, but improved my weight. In the first month I was able to get rid of 5 pounds by simply changing the way I approached spending on fast food. Now I am more likely to bring my lunch than to buy it. I am not upset, but empowered to make positive choices to improve my life.

    America is the world's largest food exporter. But the worst drought in half a century is hitting corn and wheat harvests. The drought across the central United States adds to concerns about world food supplies and prices in the coming years.

    Experts say by 2050, the world will have to produce at least sixty percent more food to feed a population growing bigger and bigger. China, a major food importer, is looking for producers around the world to guarantee future food supplies.

    China has invested in food production in Australia and New Zealand. A new source of supply is Ukraine. Ukraine was known as the breadbasket of Europe because of rich corn and wheat harvests a century ago.

    Galyna Kovtok is chief executive of Ukraine's largest agricultural business, ULF. She predicts that within a few months her company will be approved to export corn to China. That will make Ukraine the first country outside the Americas to do so.

    ULF will soon have almost two million tons of elevator storage capacity as it prepares for the Chinese market. Chinese money is financing the building of six grain elevators. But the company's equipment is largely American, including half-million-dollar John Deere combines to harvest wheat.

    ULF'S grain production per hectare (公顷) is now halfway between Ukrainian averages and the high yields of the American Midwest. But farming depends on the weather. Across the Black Sea region—in Ukraine, Russia and Kazakhstan--drought this year is pushing harvests down by fifteen to twenty percent.

    Traditionally, the Black Sea region is the main source of wheat for North Africa and the Middle East. But this year, on the supply side, Russia may have to stop exports. And, on the demand side, Africa and the Middle East are now competing with China.

    At the same time, a new report says large parts of Asia may face long periods of severe drought within ten years. It says northern China, India, Afghanistan, Mongolia and Pakistan will be especially hard hit. It says other parts of Asia are likely to face longer and wetter monsoon seasons (雨季) because of climate change.

    On a sunny, spring day, a group of children, four to seven years old, sit on their bicycles. They wear helmets to protect their heads and gloves to protect their hands. Their mothers, standing nearby, watch them closely. The children are ready to learn how to ride. Rachel Varn still remembers how she felt riding a bicycle for the first time. She says, "It is probably the biggest confidence booster (提升). It gives kids such a sense of independence and self-guidance." Now, her job is helping children experience that moment.

    Rachel Varn left her job of selling bicycles to become a trainer for bicycle riding last year. She founded Pedal Power Kids to teach bicycle education. Before starting a ride she teaches the children how to make sure the bicycles are in good condition for safe use. She calls it " the ABC quick check." "A" is for air. she explains, "We have to check out tires before we ride. "B" is for brakes. We want to make sure our brakes work before we find ourselves at the top of a hill about to go down. And "C" is for chain." She says the chain must be clean.

    The rest of the training is more fun. The children learn riding skills, from balance and pedaling to turning, starting and stopping. And they learn to keep their eyes up and look ahead while riding. Varn says many children struggle to do this. They look down at the pedals instead. She adds, " Obviously that doesn't allow them to see what's going on around them, and it doesn't allow them to turn properly either." Varn says watching where you are going helps you turn easier.

    Learning to ride a bicycle can open a whole new world to children. It gives them a sense of accomplishment and freedom. They become more sensitive to their surroundings and better able to make safe, smart decisions going from one place to another. Varn's goal is to get more children on two wheels. She says," That's really a great way for kids to be active and develop healthy habits. It helps reduce pollution and just keep families and communities connected."
