It is amazing to note that the Internet is still such a new device, and yet it is one of the fastest and most powerful media tools. But think about it for a moment. On the Internet, a big online company can be run by only two guys in their garage. So it is only reasonable then, that people shopping online would be a little leery of the security levels.

Internet giants such as Microsoft knew consumer confidence was the key to getting virtual (虚拟的) shopping off the ground, and they work hard to make people feel safe to shop online.

Credit card companies, too, quickly saw the potential For online shopping, and have installed things like online shopping insurance for people. If you ever have a problem with your online credit purchases, many credit card companies will happily refund (退还) your money and then set their claws on the company that wronged you。 Now that’s buying power!

There are other bonuses for online shoppers, of course. No line-ups,for one. No annoying mall shopping carts with broken wheels and kids crying because their parents won’t get them what they want.

When shopping on1ine, consumers can sit down, have a coffee, and wear their slippers, not having to worry about their hair or parking, and just clicking through sale after sale.

Comparison shopping couldn’t be any easier. And thanks to courier companies (快递公司) getting in on the act you never need to wait longer than a day or two to get those all important purchases delivered right to your door.

No wonder so many companies are shaking their heads at traditional retailing and instead looking to the “virtual” world to attract online shoppers.

house, the walls and ceiling burst apart as if a bomb had gone off inside. This explosion is caused by the low air pressure at the center of a tornado.

The pressure at the center of a tornado is usually 13 pounds per square inch. However,inside the house the air pressure is normal, about 15 pounds per square inch.The difference of 2 pounds per square inch between the inside and outside pressure may not seem like much. But suppose a tornado passes over a small building that measures 20 by 10 by feet. On each square inch of the building, there is 2 pounds of pressure from the inside

that is not balanced by air pressure outside the building. On the ceiling, that adds up to an unbalanced pressure of 57600 pounds. The pressure of the four walls adds up to 172800 pounds.

If windows are open in the building, some of the inside air will rush out through them.This will balance the pressure inside and outside the building.But if the windows are shut tightly, the huge inside pressure may cause the building to burst.

Unfortunately, heavy rain often occurs in the storms that later produce tornadoes,so people often shut their windows. This may cause far worse damage later.
