Five Tips to Make Your House Look Greener

There are plenty of ways to make your house look greener. It doesn't matter how many people reside in your home. It doesn't even matter what is the size of your home. What matters is how your house looks and how it affects you and others residing in it.

It is very necessary to make your house look greener because it has a direct impact on your health. If you keep your house greener, you will get rid of many dangerous diseases. Here are some ways to keep it greener.

1. Good and reliable Interior

Indoor material, like windows, doors, cupboards, etc. must be of good quality. These things play an important role to clean the house. Doors and cupboards must be of high quality wood. Aluminium windows must be used. You must use high-quality paints for walls, doors, windows and cupboards.

2. Using wider windows and doors for ventilation.

Oxygen is a necessary element to enable you to live alive. For healthy life, windows and doors must be wide and usually be kept open at least for 15 hours a day, as ventilation of air makes you fresh and healthy.

3. Placing plants especially flowers at various places

No one wants an empty house, and plants definitely play a refreshing role. First, the plants provide you with oxygen necessary for survival. Second, plants and especially flowers spread heart-attracting fragrance. All unhealthy odors are eradicated from your home and you feel fresh whenever you are inside it. Flowers also make your home interior look more appealing.

4. Disposing off wastes away from home regularly

It's very important to throw away household wastes far from your house every day. When wastes are kept untouched for many days, they attract bacteria and viruses. Flies and mosquitoes also start gathering and increasing at such places. As a result, diseases are caused.

5. Using anti-bacterial materials for washing floors and contents

Usually unclean fans, floors and walls breed bacteria and viruses, which are then carried by flies and mosquitoes. These carriers then infect the humans by contact through contaminated food or direct attacks on human body. It's always recommended to use anti-bacterial or anti-viral

cleaners for fans, floors, walls, laptops, and TVs.

Amphibious Architecture: Flood-Proof Home Designs

Instead of trying to beat back the rising flood, innovative amphibious buildings can adapt to the rising flood. 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 UK's First Amphibious House

The UK's 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 Nigeria

Residents 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. Makoko's 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.

3.250,000 residents of Makoko in Nigeria will be homeless if officials tear down their houses. T

In capsule hotels, each guest stays in a small sleeping space called capsule. It measures about 2 meters in length and1 meter in both width and height.

It is a type of hotel first developed in Japan intended to provide cheap, basic overnight accommodation for guests who do not require the services offered by traditional hotels. Facilities differ, but most include a television and wireless internet connection. There are many buttons in the capsule. One turns on the light, one turns on the TV, one controls the channels. There is a radio and an alarm clock built in. The open end of the capsule can be closed, for privacy, with a curtain or a fiber glass door. Luggage is stored in a locker. Clothes and shoes are sometimes exchanged for a yukata and slippers on entry. Washrooms are communal. Guests are asked not to smoke or eat in the capsules. Some hotels also provide restaurants (or at least vending machines), pools, and other entertainment facilities. Capsules are used primarily by men. Some capsule hotels offer separate sections for male and female guests.

The benefits of these hotels are convenience and price, usually around ￥2000-4000 (USD 25-50) a night. They provide a place for those who may be too drunk to return home safely.

二、阅读理解：阅读下面的短文，根据文章内容进行判断，正确为“T”，错误为“F”。

The fridge is considered necessary. It has been so since the 1960s when packaged food list appeared with the label: "Store in the refrigerator."

In my fridgeless Fifties childhood, 1 was fed well and healthy. 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 -- 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. The statement "In my fridgeless fifties childhood, I was fed well and healthily." suggests that the author was well-fed and healthy even without a fridge in his fifties.

2. The author says that nothing was wasted before the invention of fridges because people had effective ways to preserve food.
