Americans are used to ordering things ranging from French fries to popcorn in small, medium or supersize. Now those same decision-making skills may become rueful in the bathroom, thanks to an innovative plumbing technology: dual-flush toilets. The new invention is the industry’s latest attempt to help reduce water usage, a movement that hasn’t always gone smoothly. The last big toilet makeover came more than a decade ago, when the U.S. government decreed that new toilets should use just 1.6 gallons of water per flush, down from the 3.5-gallon standard. But consumers complained that it often took two or more flushes to clear the bowl; so many people preferred the old toilets that some plumbers imported them illegally from Canada.

【With the 4G telecommunications systems now starting to be deployed,people are looking towards the development of 5th generation or 5G technology services.Although the deployment of any wireless or cellular system take years,development of the 5G technology systems is being investigated.The new 5G technologies will need to be chosen developed and perfected to enable timely and reliable deployment. The new 5th generation,5G technology for cellular systems will probably start to come to fruition around 2020. The current status of the 5G technology for cellular systems is very much in the early development stages.Many companies are looking into the technologies that could be used to become part of the system.In addition to this,a number of universities have set up 5G research units focused on developing the technologies for 5G. In addition, the standards bodies,particularly 3GPP are aware of the development but are not actively planing the 5G systems yet.Many of the technologies to be used for 5G will start to appear in the systems used for 4G and then as the new 5G cellular system starts to formulate in a more concrete manner,they will be incorporated into the new 5G cellular system. The major issue with 5G technology is that there is such an enormously wide variation in the requirements:super fast downloads to small data requirements for IoT than any one system will not be able to meet these needs.Accordingly a layer approach is likely to be adopted.As one commentator stated:5G is not just a mobile technology.It is ubiquitous access to high low data rate services.】 Based on the paragraph above,at present,5G technology for cellular systems （ ）, many of the technologies to be used for 5G （ ） in the systems used for 4G,the major issue facing with 5G technology is （ ）.A．has matured B．has setup its standards C．is very much in the early development stages D．is in use A．is being developed B．already appeared C．will not appear D．will start to appear A．super fast downloads B．small data requirements for IoT C．4G system has already satisfied these needs D．an enormously wide variation in the requirements

Can animals be made to work for us?Some scientists think that one day animals may be trained to do a number of simple jobs that are now done by human beings.
They point out that at a circus,for example,we may see elephants,monkeys,dogs and other animals doing quite skillful things．Perhaps you have seen them on the television or in a film．If you watch closely,you may notice that the trainer always gives the animal a piece of candy or a piece of fruit as a reward．The scientists say that many different animals may be trained to do a number of simple jobs if they know they will get a reward for doing them.
Of course,as we know,dogs can be used to guard a house,and soldiers in both old and modem times have used geese to give warning by making a lot of noise when a stranger or an enemy comes near．But it may be possible to train animals to work in factories．In Russia,for example,pigeons which are birds with good eyesight,are being used to watch out for faults in small steel balls that are being made in one factory．When the pigeon sees a ball which looks different from others,it touches a steel plate with its beak．This turns on a light to warn people in the factory．At the same time a few seeds are given as a reward．It takes three to five weeks to train a pigeon to do this and one pigeon can inspect 3 000 to 4 000 balls an hour.

问答题The percentage of immigrants (including those unlawfully present) in the United States has been creeping upward for years. At 12.6 percent, it is now higher than at any points since the mid 1920s. We are not about to go back to the days when Congress openly worried about inferior races polluting America’s bloodstream. But once again we are wondering whether we have too many of the wrong sort of new comers. Their loudest critics argue that the new wave of immigrants cannot, and indeed do not want to, fit in as previous generations did. We now know that these racist views were wrong. In time, Italians, Romanians and members of other so-called inferior races became exemplary Americans and contributed greatly, in ways too numerous to detail, to the building of this magnificent nation. There is no reason why these new immigrants should not have the same success. Although children of Mexican immigrants do better, in terms of educational and professional attainment, than their parents, UCLA sociologist Edward Telles has found that the gains don’t continue. Indeed, the fourth generation is marginally worse off than the third. James Jackson, of the University of Michigan, has found a similar trend among black Caribbean immigrants. Telles fears that Mexican-Americans may be fated to follow in the footsteps of American blacks that large parts of the community may become mired in a seemingly state of poverty and Underachievement. Like African-Americans, Mexican-Americans are increasingly relegated to segregated, substandard schools, and their dropout rate is the highest for any ethnic group in the country. We have learned much about the foolish idea of excluding people on the presumption of the ethnic/racial inferiority. But what we have not yet learned is how to make the process of Americanization work for all. I am not talking about requiring people to learn English or to adopt American ways; those things happen pretty much on their own, but as arguments about immigration hear up the campaign trail, we also ought to ask some broader question about assimilation, about how to ensure that people, once outsiders, don’t forever remain marginalized within these shores. That is a much larger question than what should happen with undocumented workers, or how best to secure the border, and it is one that affects not only newcomers but groups that have been here for generations. It will have more impact on our future than where we decide to set the admissions bar for the latest wave of would-be Americans. And it would be nice if we finally got the answer right.

单选题Passage2The way people work has changed. The increasing use of technology presents new and continual challenges to small and large businesses，employees and managers，teachers and students.Everyone，it seems，is being affected by the technological revolution. Store clerks，for example，now use increasingly complex computerized cash registers，while university professors must learn to adapt their teaching skills in order to lead distance learning course.In today's world，training and learning do not stop when we finish school；they must now continue throughout our working lives. The Hong Kong government conducted a survey on the employment concerns，and training needs of its workforce. For many managers and other professionals the biggest challenge，as well as change，in the workplace，was the increased use of computers and computerized machinery or equipment. The need for experienced employees who could use this kind of equipment rose drastically. Many of those in the workplace at this time experienced changes in job requirements and had to attend job-related training or re-training courses.The changing work environment is also affecting education and how we learn. In Finland, a report on strategies for education and training in the information age discussed the changing roles of both teacher and student. With the increased use of technology and the growth of distance learning, the teacher has become more of a tutor who guides a student, rather than a lecturer. In turn, the student has to take more responsibility for his or her learning in the absence of direct teacher contact. The report also stressed that high school and university students should learn computer skills in order to cope with the demands of the future workplace.The Finnish report also highlighted the need for teacher training, and re-training, and suggested that the salaries and job descriptions of teachers be reviewed because of future demands expected in their jobs. Previously university professors may have held lectures between the weekday hours of 9:00A.M. and 5:00 P.M. in large halls filled with students. Now, they may spend part of their day lecturing larger groups of students on campus, and then conduct afternoon or evening classes online, with students in five different countries.As technologies grow and develop, ongoing training will continue to be necessary. To be successful in the workplace, people will not stop learning when they leave school-lifelong learning will become a way of life.From the first paragraph of the passage we know that_______.A
everyone has to learn how to use complex computersB
technological revolution has brought changes to people's workC
the use of new technology has got small business into large onesD
even university professors have to learn the new technology in distance courses

问答题Practice 7 In recent years intellectual property has received a lot more attention because ideas and innovations have become the most important resource, replacing land, energy and raw materials. As much as three-quarters of the value of publicly traded companies in America comes from intangible assets, up from around 40% in the early 1980s. “The economic product of the United States”, says Alan Greenspan, the chairman of America’s Federal Reserve, has become “predominantly conceptual”. Intellectual property forms part of those conceptual assets. In information technology and telecoms in particular, the role of intellectual property has changed radically. What used to be the preserve of corporate lawyers and engineers in RD labs has been speedily embraced by the boardroom. “Intellectual-asset management” now figures as a strategic business issue. In America alone, technology licensing revenue accounts for an estimated $45 billion annually; worldwide, the figure is around $100 billion and growing fast. Technology firms are seeking more patents, expanding their scope, licensing more, litigating more and overhauling their business models around intellectual property. Yet paradoxically, as some companies batten down the hatches, other firms have found ways of making money by opening up their treasure-chest of innovation and sharing it with others. The rise of open-source software is just one example. And a new breed of companies has appeared on the periphery of today’s tech firms, acting as intellectual-property intermediaries and creating a market for ideas.
