    The argument over New York's ban on sales of super- sized high- sugar drinks continue to go up. Meanwhile, the Coca- Cola Company recently made a two-minute advertisement showing itself as part of the solution to America's obesity（肥胖）problem. Food writers and doctors eyed it with disapproval. "Oh, please!” wrote famous author Marion Nestle.
    There really isn't anything to say about drinking soda (汽水). A super-sized drink with 123 grams of sugar is short cut to heart disease and obesity. One in three Americans today is obese, compared to one in five in 1990. There's no single cause for this increase, but one is almost certainly the linking for soda drinks.
     Other nations drink soda more responsibly. Japan drinks 34 liters per person, compared to 165 liters per person in the United States. More examples are Russia (30 liters per person), Italy (49 liters per person) and South Korea (27 liters per person). In the United States, soda is the most consumed drink; they drink almost twice as much as they do bottled water.
     Soda outside America isn't necessarily healthier. It's in the way that people drink it. As with most things like food and drink, the Italians do soda better. It has 23 grams of sugar in a standard-sized bottle. They drink it as a mid- afternoon treat in limited quantities, which is how Americans used to drink it. They don't have it like water at every meal.
   The problem is not soda but the people. Yes, the industry targeted children by placing machines in schools. Yes, they spent millions protecting sales of their products. But, with all the evidence, we're the ones who are buying it.

Electricity bills can be highly expensive and the power we consume comes at an even greater cost to the environment when you consider that over 85% of the electricity produced in the United States comes from fuels. Whether you’re concerned about cleaning up the environment or you simply want to reduce your electricity bill，residential wind power generators（发电机）could be a solution.
Producing wind power at home will not work for everyone. If you live in a over-populated residential area，there may be certain laws and zoning requirements that prohibit the use of windmills (风车). If you live on 1 acre of land or more, you probably won’t have any issues but you should investigate carefully to make sure that wind power generators are both legal and practical where you live. Even if there are no laws or regulations prohibiting wind power generators you still need to be in a location that gets enough wind on a regular basis.
Some producers of wind generators recommend that you live in an area with wind speeds that average at least 10 mph. Newer models have been developed recently that can operate with wind speeds as low as 4 mph but maximum efficiency is achieved at higher wind speeds. Before you fix a wind powered system, you will have to determine your power requirements. Will you be using it to charge a small battery for a boat or vehicle or will you need enough power to run your entire household and be completely off the grid (电网)? Once you know what your power requirements are，you can start shopping around for a system that can meet those needs.
Wind power generators are a great solution for a lot of people. They’re an ideal solution for remote locations where it would be impractical or simply too expensive to tap into the grid. They are quiet and totally clean，producing no pollution. They require no fuel and very little maintenance. Residential wind power offers a lot of benefits but it’s not for everyone. You’ll have to have some money up front to pay for the system and equipment; however, you could save quite a bit of money if you’re able to do much of the work yourself. You’ll also need to live in an area that gets enough wind to make the equipment worthwhile. You’ll need to do your homework before you make a purchase, but wind power generators could be a great solution for producing clean, low-cost energy.
