Think about the different ways that people use the wind. You can use it to fly a kite or to sail a boat. Wind is one of our cleanest and richest power sources, as well as one of the oldest. Evidence shows that windmills(风车) began to be used in ancient Iran back in the 7th century BC. They were first introduced to Europe during the 1100s, when armies returned from the Middle East with knowledge of using wind power.

For many centuries, people used windmills to grind(磨碎) wheat into flour or pump water from deep underground. When electricity was discovered in the late 1800s, people living in remote(偏远的) areas began to use them to produce electricity. This allowed them to have electric lights and radio. However, by the 1940s when electricity was available(可利用的) to people in almost all areas of the United States, windmills were seldom used.

During the 1970s, people started becoming concerned about the pollution that is created when coal and gas are burned to produce electricity. People also realized that the supply of coal and gas would not last forever. Then, wind was rediscovered, though it means higher costs. Today, there is a global movement to supply more and more of our electricity through the use of wind.

This day marks the rising of a new food startup, the first company to be financed entirely by the crowd, and of it every business thus relies on thousands of customers to grow. Lisa, 25, its main founder and CEO, believes it will be a path that will become increasingly popular, and ultimately will produce more thriving(繁荣的)businesses from the scratch.

“In the food industry, no venture capital (VC, 风险投资) will even look at you until you’ve hit a million in sales. As a fresh hand in business, unless you’re independently wealthy, you will likely need to raise some money before then,” Lisa complained. So few businesses approached VC firms at the beginning. It was no exception with her. Thus, she turned to a new financing tool at hand, crowdfunding, to raise money from the crowd who’d like to take a bet on her company.

But for a company, it didn’t make sense to seek investments when all they had was an idea and a few months of consumer testing data. The food market is extremely competitive. No investor would put money behind a totally unproven new super food product founded by a bunch of twenty-somethings. “But we had a story. And crowds love stories.” Lisa said delightedly. So she put together an online crowdfunding campaign, explaining how she began working with this amazingly nutritious plant in the Peace Corps and then started selling it in the U.S. to support the poor in the West Africa.

On the online platform where they were to raise the money, a friend convinced them to change their goal from $20,000 to $50,000. Lisa stayed up all night worrying they wouldn’t hit it. But they reached $24,000 in 24 hours and ended their funding with $53,000. Seeing the number, Lisa said, “Thank you! To my crowd and for your belief!”

“Old wives’ tales” are beliefs passed down from one generation to another. For example,most of us remember our parents’ telling us to eat more of certain foods or not to do certain things. Is there any truth in these teachings? Some of them agree with present medical thinking,but others have not passed the test of time.

Did your mother ever tell you to eat your carrots because they are good for your eyes? Scientists now report that eating carrots can help prevent a serious eye disease called macular degeneration. Eating just one carrot a day can reduce the possibility of getting this disease by 40%. Garlic is good for you,too. It can kill the type of virus that causes colds.

Unfortunately, not all of Mom’s advice passed the test of medical studies. For example, generations of children have been told not to go swimming within an hour after eating. But research suggests that there is no danger in doing so. Do sweets cause tooth problems?Well, yes and no. Sticky sweets made with grains(谷物) tend to cause more problems than sweets made with simple sugars.
