单选题Opinion polls are now beginning to show an unwilling general agreement that, whoever is to blame and whatever happens from now on, high unemployment is probably here to stay. This means we shall have to find ways of sharing the available employment more widely. But we need to go further. We must ask some fundamental questions about the future of work. Should we continue to treat employment as the norm? Should we not create conditions in which many of us can work for ourselves, rather than for an employer? Should we not aim to revive the household and the neighbourhood, as well as the factory and the office, as centres of production and work? The industrial age has been the only period of human history in which most people's work has taken the form of jobs. The industrial age may now be coming to an end, and some of the changes in work patterns which it brought about may have to be reversed. This seems a discouraging thought. But, in fact, it could offer the prospect of a better future for work. Universal employment, as its history shows, has not meant economic freedom. Employment became widespread when the enclosures of the 17th and 18th centuries made many people dependent on paid work by depriving them of the use of the land, and thus of the means to provide a living for themselves. Then the factory system destroyed the cottage industries and removed work from people's homes. Later, as transport improved, first by rail and then by road, people travelled longer distances to their places of employment until eventually, many people's work lost all connection with their home lives and places in which they lived. Meanwhile, employment put women at a disadvantage. It became customary for the husband to go out to paid employment, leaving the unpaid work of the home and family to his wife. All this may now have to change. The time has certainly come to switch some effort and resources away from the impractical goal of creating jobs for all, to the urgent practical task of helping many people to manage without full-time jobs.

单选题Customer experience is the internal and subjective response customers have to any direct or indirect contact with a company. (71)______Indirect contact most often involves unplanned encounters with representations of a company's products, services, or brands and takes the form of word-of-mouth recommendations or criticisms, advertising, news reports, reviews, and so forth. Such all encounter could occur when Google's whimsical holiday loges pop up on the site's home page at the inception of a search, or it could be the distinctive "potato, potato" sound of a Harley-Davidson motorcycle's exhaust system. (72)______ The secret to a good experience isn't the multiplicity of features on offer. Microsoft Windows, which is rich in features, may provide what a corporate IT director considers a positive experience. (73)______A customer's experience with an Apple device such as the iPod begins well before the purchaser turns it on perhaps because of the dancing silhouettes in the TV advertisements. Furthermore, the origami-like (and recyclable) packaging enfolds the iPod as though it were a Faberge egg made for a czar. A small sticker, "Designed in California, Made in China," communicates the message that Apple is firmly in charge but also interested in keeping costs down. Even Windows users appreciate the device's intuitive, Mac-like feel and find that downloading tracks from iTunes is easier than buying a CD on Amazon. (74)______ A successful brand shapes customers' experiences by embedding the fundamental value proposition in all the product's features. For BMW, "the Ultimate Driving Machine" is much more than a slogan; it informs the company's manufacturing and design choices. (75) ______ BMW would not consider developing such a feature unless it amplified rather than diminished the driving experience. A. Every Apple product is designed with the, overarching purpose of making the time one spends with Apple an enjoyable experience. B. It might just be an e-mail from one customer to another. C. Direct contact generally occurs in the course of purchase, use, and service and is usually initiated by the customer. D. People's expectations are set high in part by their previous experiences with a company's offerings E. In 2000. Mercedes-Benz introduced a system that automatically controls the distance between a Mercedes and the car in front. F.

单选题Several hundred million years ago, plants similar to modern ferns covered vast stretches of the land. Some were as large as trees, with giant fronds bunched at the top of trunks as straight as pillars. Others were the size of bushes and formed thickets of me undergrowth. Still others lived in the shade of giant club mosses and horsetails along the edges of swampy lagoons where giant amphibians swam. A great number of these plants were true ferns, reproducing themselves without fruits or seeds. Others had only the appearance of ferns. Their leaves had organs of sexual reproduction and produced seeds. Although their "flowers" did not have corollas these false ferns(today completely extinct)ushered in the era of flowering plants. Traces of these floras of the earliest times have been preserved in the form of fossils. Such traces are most commonly found in shale and sandstone rocks wedged between coal beds. Today only tropical forests bear living proof of tile ancient greatness of ferns. The species that grow there are no longer those of the Carboniferous period, but their variety and vast numbers, and the great size of some, remind us of the time when ferns ruled the plant kingdom.

单选题There were two widely divergent influences on the early development of statistical methods. Statistics had a mother who was dedicated to keeping orderly records of governmental units (state and statistics come from the same Latin root, status) and a gentlemanly gambling father who relied on mathematics to increase his skill at playing the odds in games of chance. The influence of the mother on the offspring, statistics, is represented by counting, measuring, describing, tabulating, .ordering, and the taking of censuses - all of which led to modern descriptive statistics. From the influence of the father came modern inferential statistics, which is based squarely on theories of probability. Descriptive statistics involves tabulating, depicting, and describing collections of data. These data may be either quantitative, such as measures of height, intelligence, or grade level variables, that are characterized by an underlying continuum or the data may represent qualitative variable, such as sex, college major, or personality type. Large masses of data must generally undergo a process of summarization or reduction before they are comprehensible. Descriptive statistics is tool for describing or summarizing or reducing to comprehensible form the properties of an otherwise unwieldy mass of data. Inferential statistics is a formalized body of methods for solving another class of problems that present great difficulties for the unaided human mind. This general class of problems characteristically involves attempts to make predictions using a sample of observations. For example, a school superintendent wishes to determine the proportion of children in a large school system who come to school without breakfast, have been vaccinated for flu, or whatever. Having a little knowledge of statistics, the superintendent would know that it is unnecessary and inefficient to question each child; the proportion for the entire district could be estimated fairly accurately from a sample of as few as 100 children. Thus, the purpose of inferential statistics is to predict or estimate characteristics of a population from knowledge of the characteristics of only a sample of the population.
