These buildings are ready for whatever Mother Nature might throw at them - even 10-foot floodwaters. Let，s take a look at just two of them.The UKs First Amphibious HouseThe UKs first amphibious house is located on the Thames River. And the first amphibious building in Britain will be completed soon. Baca Architects designed this home for a couple who wanted to live on a flood-prone island, an island easy to be attacked by floods, in the Thames River. This building is equipped with a terraced landscape. And this terraced landscape acts as an early warning system when the waters are rising. The terraces will be filled with water before the wet dock under the house does, and then the home itself will slowly rise to stay above the water.Solar Powered Floating School in NigeriaResidents of Makoko in Nigeria have been building houses on stilts for generations. People there go from one house to another by canoe. As sea levels are rising, officials threaten to tear down the entire community. If these houses are tore down, 250,000 people will be homeless and have to look for a new place to live. Architects found a solution in floating structures with improved sanitation conditions. The first completed example is a three-storey solar-powered school.This amazing floating school addresses social, physical and ecological needs. Built on top of 256 recycled blue barrels, the school buildings are made of triangular bamboo and wood. Makokos residents made full use of their skills when building these structures. With three levels, the solar-powered high school has room for 100 local kids and recycles rainwater to flush the toilets. And the cost for the whole school structures was under $7,000.1.

The milkman came every day, the grocer, the butcher （肉商），the baker, and the ice-cream man delivered two or three times each week. The Sunday meat would last until Wednesday and surplus（剩余的）bread and milk became all kinds of cakes. Nothing was wasted, and we were never troubled by rotten food. Thirty years on food deliveries have ceased, fresh vegetables are almost unobtainable in the country.The invention of the fridge contributed comparatively little to the art of food preservation. Many well-tried techniques already existed - natural cooling, drying, smoking, salting, sugaring, bottling.What refrigeration did promote was marketing marketing hardware and electricity,marketing soft drinks, marketing dead bodies of animals around the world in search of a good price.Consequently, most of the world，s fridges are to be found, not in the tropics where they might prove useful, but in the rich countries with mild temperatures where they are climatically almost unnecessary. Every winter, millions of fridges hum away continuously, and at vast expense, busily maintaining an artificially-cooled space inside an artificially-heated house 一- while outside, nature provides the desired temperature free of charge.The fridge，s effect upon the environment has been evident, while its contribution to human happiness has been not important.1.

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 online, 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.1.
