更多“Man has never ceased to search…”相关的问题
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______.
A．the author was well-fed and healthy even without a fridge in his fifties
B．the author was not accustomed to using fridges even in his fifties
C．there was no fridge in the author' s home in the 1950s
D．the fridge was in its early stage of development in the 1950s

NASA is working with Moshier to help develop his flying machine. The first users are likely to be military.

His purpose is settled and decided. He knows what he wants and he just finds it and buys it, but cares little about the price. All men simply walk into a shop and ask the assistant for what they want. If the shop has it, the salesman quickly takes it out, and the business of trying it on follows at once. If all is well, the deal(买卖) can be and is often completed in less than five minutes, with hard any chat and to everyone's satisfaction.
For a man, small problems may begin when the shop does not have what he wants, or does not have exactly what he wants. In that case the salesman tries to sell the customer something else—he offers the nearest he can to the thing asked for. He would say, "I know this jacket is not the style. you want, Sir, but would you like to try it on for size？ It happens to be the color you mentioned." Few men have patience (耐心 ) with this treatment, and the usual answer is, "This is the right color and may be the right size, but I should be wasting my time and yours by trying it on."
Now how docs a woman go about buying clothes？ In almost every respect (方面) she does so quite differently. Her shopping is not often based on need. She has never fully made up her mind about what she wants, and she is only "having a look around". She is always open to what the salesman tells her, even to what her friends tell her. She will try on any number of things. What is most important in her mind is the thought of finding something that everyone thinks suits her. Besides, most women have an excellent sense of value when they boy clothes. The), are always ready for the unexpected bargain (便宜货). Faced with a roomful of dresses, a woman may easily spend an hour going from one counter to another before selecting the dresses she wants to try on. It takes time, but surely it is enjoyable to women shoppers. Most dress shops provide chairs for the waiting husbands.
When a man is buying clothes, ______.
A．he buys cheap things and does not care about the quality
B．he chooses things that others recommend
C．he does not mind how much he has to pay for the right things
D．he buys good quality things, so long as they are not too expensive
For a man, slight problems may begin when the shop does not have what he wants, or does not have exactly what he wants. In that case the salesman, as the name implies, tries to sell the customer something else, he offers the nearest he can to the article required. No good salesman brings out such a substitute bluntly; he does so with skill and polish; "I know this jacket is not the style. you want, sir, but would you like to try it for size. It happens to be the color you mentioned. " Few men have patience with this treatment, and the usual response is :" This is the right color and may be the right size, but I should be wasting my time and yours by trying it on.
Now how does a woman go about buying clothes？ In almost every respect she does so in the opposite way. Her shopping is not often based on need. She has never fully made up her mind what she wants, and she is only" having a look round". She is always open to persuasion; indeed she sets great store by what the saleswoman tells her, even by what companions tell her. She will try on any number of things. Uppermost in her mind is the thought of finding something that everyone thinks suits her. Contrary to a lot of jokes, most women have an excellent sense of value when they buy clothes. They are always on the lookout for the unexpected bargain. Faced with a roomful of dresses a woman may easily spend an hour going from one rail to another, to and fro, often retracing her steps, before selecting the dresses she wants to try on. It is a laborious process, but apparently an enjoyable one. Most dress shops provide chairs for the waiting husbands.
According to the passage, when a man is buying clothes, ______.
A．he buys cheap things, regardless of quality
B．he chooses things that others recommend
C．he does not mind how much he has to pay for the right things
D．he buys good quality things, so long as they are not too dear
