Saving the Environment: One Home at a Time
Pollution can be seen not only throughout the world, but also in our own homes. It comes from household chemicals, the amount of water people use and the waste people produce and throw away. What can be done to stop this pollution? Surprisingly, a person can help save the environment by doing simple things.
First, we need to recycle, which allows products to be used over and over again. Recycling can also reduce the number of trees cut down to produce paper products. It takes very little effort. It is not hard to place plastic and glass bottles, aluminum cans and paper in a bin. Anyone can do it.
Second, we need to watch the amount of water used at home. It can be conserved by taking short showers instead of baths, repairing leaky faucets, using the dishwasher or washing machine only when fully loaded, or simply turning the faucet off while brushing your teeth.
Third, we need to reduce waste. We need to recycle whenever possible, but shouldalso try to use this waste effectively. For example, grass clippings and food scraps can be made into compost for plants. The average person produces 4.3 pounds of waste every day, but we can reduce that amount by recycling and reusing.
If we do our part in our own homes, we can help keep the planet from becoming more polluted.

RECYCLING
HAVE YOU EVER THOUGHT THE FACT THAT MOST OF WHAT YOU OWN WILL ONE DAY BE THROWN OUT ? THNK ABOUT YOUR CLOTHES, THE TELEVISION , AND THE STOVE. THEY WILL TEAR OR BREAK DOWN. OR YOU MAY JUST WANT TO GET NEW, BETTER THINGS. BUT WHERE DO THINGS GO WHEN YOU THROW THEM OUT ?
THE BAD NEWS IS THAT MOST OF IT GOES TO A LANDFILL. A LANDFILL IS A BIG HOLE IN THE GROUND. IT MAY HAVE A CONCRETE OR PLASTIC LINER. THIS LINER KEEPS CHEMICALS FROM SEEPING INTO THE GROUNDWATER AROUND THE LANDFILL.TRASH TRUCKS FILLED WITH ALL THE THINGS THAT PEOPLE THROW OUT GO TO THE LANDFILL.THEY DUMP THEIR LOADS INTO THE HOLE. BULLDOZERS COVER EVERYTHING WITH SOIL. BUT THERE IS A BETTER WAY. AND SINCE WE ARE RUNNING OUT OF LANDFILL SPACE, MORE PEOPLE ARE DOING IT.
THE BETTER WAY IS RECYCLING . RECYCLING LETS MANY THINGS BE USED AGAIN. GIVE AWAY AN OLD TV OR STOVE. THEY CAN BE FIXED SO THAT SOMEONE ELSE CAN USE THEM . CLOTHES CAN BE SENT TO PEOPLE WHO NEED THEM. MOST GLASS , PAPER, PLASTIC, AND METAL IS RECYCLABE. WHEN PEOPLE RECYCLE THESE THINGS, IT HELPS THE ENVIRMONMENT. IT SAVES SPACE IN LANDFILL.( PEOPLE TAKES UP MORE SPACE IN LANDFILL THAN ANY OTHER THING!)
SOME PEOPLE HAVE RECYCLE BINS. THEY PUT THEIR PAPER,METAL,GLASS, AND PLASTIC INTO THE BIN. A SPECIAL TRUCK TAKES THESE THINGS TO A PROCESSING CENTER. OTHER PEOPLE MUST DRIVE TO A RECYCLING CENTER AND DROP OFF THEIR THINGS.
WHAT HAPPENS AT THE RECYCLING CENTER? PAPER IS SHREDDED AND THEN MIXED WITH WATER AND WOOD PULP TO MAKE A NEW PAPER. GLASS,METAL, AND PLASTIC ARE MELTED DOWN. THEN THEY ARE POURED INTO MOLDS TO FORM NEW THINGS. GLASS JARS ARE MELTED DOWN AND BECOME NEW GLASS JARS. RECYCLING LETS THINGS BE USED OVER AND OVER.

one extra sentence you do not need to use. Write the correct letter in the box.
Choose from the following sentences to fill the spaces in the text. There is ONE extra.
A. Using a microwave for cooking a large food mass is difficult due to limited penetration of
microwaves.
B. This can be overcome by leaving the food to stand for a few minutes when cooking is
completed.
C. It is advised that the water should be poured slowly into another container that already
contains the powder.
D. In this way, buying a microwave oven with a turntable ensure the food is cooked
throughout.
E. Conversely the microwaves do not heat glass, ceramic and plastic containers.
F. If the microwaves are not absorbed inside the oven, the oven can be damaged by
electrical arcs and overheating of the microwave source.
G. When water in that state is disturbed, it can suddenly and unexpectedly boil violently.
MICROWAVING
Microwaving is a method of cooking where food is bombarded by microwaves, usually
within an appliance called a microwave oven which excite the water, fat and sugar
molecules, thereby heating (cooking) both the outside and center of the food at the same
time. (1)…………………
(A common myth is that a microwave oven cooks from the center of the food outward. This
appears to happen because heat generated at the surface escapes more readily from the
surface of the food into the surrounding air.) One advantage of microwaving is that small
amounts of food can be heated very quickly, making it useful for reheating leftovers.
The disadvantage is that food which is microwaved does not undergo some of the chemical
reactions, such as browning, which makes the food visually attractive. Primitive microwave
ovens often do not cook evenly, leading to a concern that bacteria easily killed by more
traditional cooking methods may survive the quick cooking time in "cold spots", though the
food item as a whole is cooked to a safe average temperature. (2) ……
Some high-end microwave ovens are combined with a convection oven which basically
cook the food using microwave and hot air simultaneously to achieve both the fast cooking
time and browning effect.
(3) …………………
However microwave ovens are used in some fast food chains and special microwave bags
are available for cooking fowl or large joints of meat.
Professional chefs generally recommend using microwaves for a limited set of tasks,
including: melting fats (such as butter) and chocolate, cooking grains like oatmeal and grits,
cooking rice, thawing frozen meats and vegetables before cooking by other methods and
quickly reheating already-cooked foods.
Using a microwave to boil water is potentially dangerous, due to superheating. In a
microwave, water can be raised quickly to a temperature above the boiling point before
major bubbles form, especially if it is purified and in a very clean glass vessel. (4)
…………………
This effect is rare, even for scientists who try to deliberately recreate it, and any seed
whatsoever for boiling is likely to prevent the problem. Boiling water with, for instance, a
teabag already in it will prevent any dangers by providing a seed, as will using a mug that is
not perfectly clean.
The risk greatly increases when water has already been boiled once in the same container.
This situation can occur if the user of the oven boiled the water once, forgot about it, then
came back later to boil it again. The first time the water boils, the seed bubbles
(microscopic bubbles of air around which larger steam bubbles grow) are used up and
largely eliminated from the water as it cools down. When the water is heated again, the lack
of seed bubbles causes superheating, and a risk of a steam explosion when the water's
surface is disturbed.
Placing something in the water before heating can mostly alleviate this risk. If you are
planning to mix something with the water, say tea or hot chocolate, adding it before heating
will insure that the water boils. Otherwise, placing a wood object, for instance a chopstick,
in the water before heating will also work.
Care should be taken when removing heated water from a microwave. Make sure that the
hands are protected from possible liquid boil-over, place the container on a level, heat-
proof surface and stir liquid with a warm spoon. Also, never add powdered substances
(such as instant coffee or cocoa mix) to the container taken from the microwave, due to the
addition of all those seed bubbles and the potential for violent, spontaneous boiling. (5)
…………………
Metal objects, such as metal utensils, in a microwave oven can lead to dangerous situations.
Metals do not absorb microwaves effectively. Instead, metals reflect microwaves, thereby
preventing the latter from reaching the food. (6) …………………
Thin metal layers, such as metal foil and mugs with metal trim can melt or burn due to the
strong electrical currents that are generated in metal objects. However, small solid metal
objects, such as spoons, in combination with a large amount of absorbing food or liquid,
normally do not lead to problems.
