听力原文: In the old days, fresh food had to be eaten in the city no more than one or two days after it left the farm. If kept longer, it would spoil. One of the reasons behind it is that the air contains many living things that can harm our food. Some things, such as insects, can be seen by us. Others, like bacteria, can be seen only with a microscope.
All living things need water and man discovered that if this water is removed, the activity of the bacteria which causes food to go bad is prevented. In other words, we can protect some of our food by drying it. Besides, living things can only grow at certain temperatures, so we can also protect our food by heating or cooling it.
A New York man had an idea. He filled a wooden railroad car with tons of butter. The car was hooked to a train and pulled from New York to Boston. How could this be done? The butter was packed in ice, and twice during the trip more ice was added. This was the first refrigerator ear. As a matter of fact, People also used wooden boxes filled with ice to keep their food. Now we have mechanical refrigerator cars and mechanical refrigerators at home and stores and other places that need them.

C.Food must be delivered from the farm within one or two days.
D.Food must be kept in the places near the farm.

Using Your Tumble-Drier(滚筒烘干式洗衣机)
Controls Timer(计时器)Control
To operate the drier, close the door and turn the timer control to the required. The timer can be set to any time up to 120 minutes and can be reset at any time as required to increased or reduced the time to dry, but in doing so the timer knob (旋钮) must only be turned clockwise. Turning the timer backwards will cause damage and it must therefore be turned forwards even to reach the "off" position. The timer is electrically driven and will therefore only advance when there is power supplied to the drier and the drier door is closed. The time indicated on the timer includes approximately 10 minutes of tumble of tumble with the heat off. Note that the driver (主动轮) should never be turned off leaving the clothes in the drum without first completing the heat-off cool-down period.
Heat Control
There are two levels of heat which may be selected by setting the control to (low) or(high). Many materials may be dried using high but pay particular attention to setting the control to low heat for the materials mentioned under "Drying Times" below.
Automatic Door Switch
The drier will stop when the door is opened and will restart when the door is closed, allowing items to be added or taken from the drier without the need to reset the controls.
Before Tumbling
Never over spin easy-care fabrics in your automatic washing machine or spin-drier, and always follow the washing instructions given on the Care Label attached to the garment. Easy-care and synthetic fabrics dry quickly in a tumble-drier and many of them will not need ironing if they are dried in small loads. It is important to remove them from the tumble-drier as soon as the drier stops after the cool down period to avoid causing unnecessary creasing(皱褶).
Fabric Conditioner
Conditioner added to the final rinse(漂洗)in your washing machine will give even more softness to all fabrics and is invaluable for reducing the static electricity which causes fabrics containing synthetic fibers to cling and attract dirt.
After Tumbling
All clothes lose lint(碎线头)as they wear. When clothes are hung on a washing line the lint is blown away by wind. In a tumble-drier it is collected in the lint filter. The door incorporates a mesh (网眼) lint filter which is removed by lifting out vertically. It is essential to remove the lint from the filter every time the drier is used. Failure to do this will result in poor drying performance and may lead to mechanical or electrical breakdown.
Making up Loads
Maximum loads
Cottons and linens 3kg (6.5 lb) dry weight
Synthetic fabrics 1kg (2 lb) for minimum creasing or
Cotton and viscose(黏胶织物)with 2 kg if creasing is unimportant
Special finishes
Clothes should be sorted into loads of similar fabrics before drying. Towels and other cotton items which do not need ironing can be fully dried and these will be ready to store or wear as soon as they are taken from the drier. Cotton which needs ironing can be dried to a suitable dampness by reducing times suggested by approximately one quarter. Heavy fabrics should be dried separately from lightweight fabrics as a general role. Very bulky large items which do not tumble should not be dried in a tumble-drier.
Drying Times
These will depend on the size of the load, the type of fabric and the wetness of the load. It is not therefore possible to give exact drying times to cover all the variables, but experience will enable you to set the time for fully drying or damp drying as required.

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.()
3.Consumers benefited the most from fridges according to the author?()
4.What refrigeration did promote was food-preserving.()
5.The author is critical to fridges.()
