[填空题]How Ice Cream Works

[单项选择]In the last third of the nineteenth century a new housing form was quietly being developed. In 1869 the Stuyvesant, considered New York’s first apartment house, was built on East Eighteenth Street. The building was financed by the developer Rutherfurd Stuyvesant and designed by Richard Morris Hunt, the first American architect to graduate from the cole des Beaux Arts in Paris. Each man had lived in Paris, and each understood the economic and social potential of this Parisian housing form. But the Stuyvesant was at best a limited success. In spite of Hunt’s inviting facade, the living space was awkwardly arranged. Those who could afford them were quite content to remain in the more sumptuous, single-family homes, leaving the Stuyvesant to young married couple and bachelors.
The fundamental problem with the Stuyvesant and the other early apartment building that quickly followed, in the late 1870’s and early 1880’s, was that they were confined to the typical New York building lot. Th

[单项选择]
Mass production, the defining characteristic of the Second Wave economy, becomes increasingly obsolete as firms install information intensive, often robotized manufacturing systems capable of endless cheap variation, even customization. The revolutionary result is, in effect, the demassification of mass production.
The shift toward smart flex techs promotes diversity and feeds consumer choice to the point that a Wal-Mart store can offer the buyer nearly 110,000 products in various types, sizes, models and colors to choose among. But Wal-Mart is a mass merchandiser. Increasingly, the mass market itself is breaking up into differentiated niches as customer needs diverge and better information makes it possible for businesses to identify and serve micro markets.
Specialty stores, boutiques, superstores, TV home-shopping systems, computer based buying, direct mail and other systems provide a growing diversity of channels through which producers can distribute their wa
A. It promotes further development in manufacturing systems

[单项选择]At first, I thought it was just useless e-mails. It was the end of the weekend and I hadn’t checked my e-mails since late Friday afternoon. There was a long list of messages. Some I removed without reading. Others were from friends — I saved those to read later when I had more time.
One stood out from the rest for two reasons. The first was the name, Maher Nawaf, which I didn’t recognize. The second was the subject line: "pleas papers". Clearly, the e-mail was from someone who did not have a complete mastery of the English language. The message was from an Iraqi, a university research scientist in Mosul who wanted permission to reprint a research paper I had written As a scientist, I’m used to getting these kinds of requests; it’s part of the give and take among researchers that I especially like. I wrote back the next day, asking for more information about the type of work he was doing. I also wished him and his family best for their safety and well-being during this dangerous ti
