The fridge is considered a necessity. It has been so since the 1960s when packaged food first appeared with the label：“store in the refrigerator.”
In my fridgeless Fifties childhood, I was fed well and healthily. The milkman came daily, the grocer, the butcher (肉商)， the baker, and the ice-cream man delivered two or three times a week. The Sunday meat would last until Wednesday and surplus (剩余) 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. A vast way of 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 globe 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 wealthy 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 contrinbution to human happiness has been insignificant. If you don’t believe me, try it yourself, invest in a food cabinet and turn off your fridge next winter. You may miss the hamburgers, but at least you’ ll get rid of that terrible hum.
The statement “In my fridgeless Fifties childhood, I was fed well and healthily.”(Line 1, Para. 2) suggests that______.
In 1870, homes and mules were the prime source of power on U.S. farms. One horse or many decades. At that time, had a national commission been asked to forecast the horse and mule population for 1970, its answer probably would have depended on whether its consultants were of an economic mm of mind. Had they been "economists", they would have recognized that the power of steam had already been harnessed to industry and to land and ocean transport. They would have recognized further that would be only a matter of time before steam would be the prime source of power on the farm. It would have been difficult for them to avoid the conclusion that the horse and mule population would decline rapidly.
Which of the following is NOT mentioned by the author as a consequence of new technological developments？
On a four-day trip to Ethiopia, I had a dream. In my dream, I saw two men, one older and one younger, facing one another against a background of temples and pyramids. The father was speaking as he performed the oil ceremony for his son. I became excited in the possibility of performing a visiting ceremony【31】my son in Africa. For the next six days I privately wondered what【32】to use in such a ceremony. Gradually the words【33】me. By the time we arrived in Cairo, I was ready. I told my son that there was a ceremony I wanted to【34】him in the tombs in Egypt. His eyes shone with【35】. But I wondered if he would still be receptive after my next statement. In the dream I remembered that the son was oiled, as it【36】, with a dry substance. I took this to mean that powder【37】 oil was used. But what powder？ I ruled out ground grass and flowers, and finally settled on sand. Sand represents the Sahara, and sand also【38】the remains of the ancient people of Egypt. That made philosophical【39】to me, but in the real world, young adults or almost anybody for that matter,【40】disinclined to have sand poured on their hair.
