ตารางสอน 819 ๐๐๐๐ ๐๐๑๑๑ า า Let's have a look at what science and technology are preparing for us in the future. Can you imagine spending your holidays in a space hotel, having your home totally 5 computerised? What about new bones, veins and skin grown from your body cells? Homes of the Future If you like comfort, you will find it in the model home designed for the future. This model house will be wired for convenience, literally. Computer systems will link rooms, gadgets and appliances to each other and all this will be connected to the 30 Internet. 25 Space Resorts Some aerospace companies are setting up a Space Travel and Tourism Division as At the entrance, a security TV doorphone will record a picture of each visitor and it will transmit the image to monitors throughout the house. In the kitchen, appliances from the fridge to the 35 microwave oven will be programmed to order from a food delivery service and to cook recipes selected from the Internet. of the Space Transportatioท 10 part Association. One of the latest ideas is that in a few years' time you will be able to spend your vacation in a space hotel built with recycled space shuttle fuel tanks. An 15 onboard oxygen system will let guests breathe easily. The hotel will grow all its food on board hydroponically (in water containing dissolved nutrients). As soon as the guests get there, they will have an Earth- 20 like "gravity Zone" for the "space-sick." How does it sound? Will you be one of the guests to spend your holidays orbiting 322 kilometres above the Earth? Your Body Sooner than you think, scientists will grow new 40 heart valves from your own cells in laboratories. New veins and arteries will grow directly from a patient's own cells to avoid immune-system rejection. Within 10 to 20 years, laboratories will be ready to transplant hearts, livers and kidneys 45 routinely-all grown from hนman tissue in the lab. AFTER READING 5 What do these words refer to?

Read the text carefully. Years ago there wasn't a problem with rubbish because things like plastic and disposable nappies hadn't been invented. There wasn't so much packaging on items you bought either. But now with everything so over packaged wrapped and disposable we are suffering the consequences of far too much waste. The trouble is not everything can be recycled or will rot away. You used to be able to get a refund on glass bottles when you took them back to the shop. Now they are either collected from your house by the council or you can take them to a bottle bank. The fact that paper can be recycled and is easy to dispose is great, but remember paper is made from trees, which are important to the environment. The rainforests have been slowly disappearing for a while now. We need them not just because it helps with the climate. They are important as like all plants they give us oxygen. They are also a home to many animals who rely on them for their survival. The best waste is organic, dead leaves; carrot tops, onion skinร and so on all rot down and make fertile soil. This in turn will help the plants and vegetables giving them much needed food. So if youน are able to have a compost heap in your garden you'll be helping the environment and your garden wil love you for it. Acid rain is another serious problem it is damaging to plants and is caused by pollutants such as sulphur dioxide and nitrogen oxides. These come from the burning of coal, oil and gas. Dropping litter is not just a lazy thing to do it makes work for other people, is bad for the environment and looks ugly. So think before you drop litter either bin it or keep it and then bin it. When rivers and seas are polluted by waste we are not only stealing their beauty but were spoiling it for ourselves too. Our health can also suffer. Sadly accidents do occur; oil slicks sometimes happen and wreck the environment. Aninmals tend to suffer the most from these incidents. We should really have in place something that will prevent so much destruction, rather than just waiting for it to happen, then trying to clean up the damage. Nuclear waste has been the cause of controversy over the years. Radioactive material leaking out would be very serious indeed, it can cause real harm. This is why it is the most worrying. Although we are trying to stop the hole in the ozone layer getting any bigger, nuclear waste is still a serious problem. The 0zone layer protects us from harmful ultra - violet rays. Its hole has been caused by chlorofluorocarbons (cfc's) a chemical that was found in some products. Refrigerators used to contain them. So do we care enough about the earth we have inherited and our passing onto future generations? Or is it now all too late to do anything? Each one of us can make a difference and each and every one of us is responsible to the environment. It takes care of us; we should take care of it.
