更多“With rapid change of the world…”相关的问题
Given the inclination toward change, it is not surprising that tradition plays a limited role in the American culture. Those who try to uphold traditional pattern of living or thought may be seen as rigid or "old-fashioned". In a society where change is so rapid, it is not uncommon for every generation to experience a "generation gap". Sometimes parents struggle to understand the values of their children, even religious institutions have had to adapt to contemporary need of their followers. Folk singers in church services, women religious leaders, slang versions of the Bible, all reflect attempts made by traditional institutions to "keep up with the times".
High rates of change, particularly in urban areas, have contributed to a focus on the future rather than the past or present. Some Americans believe that the benefits of the future orientation are achievement and progress which enable them to have a high standard of living. Others believe that high blood pressure and stomach ulcers are the results of such a life style.
As individuals in a culture, we all have an intuitive understanding about how time is regulated, usually we do not think about the concept of time until we interact with others who have a different time orientation. Although individuals from any now cultures may view time similarly, we often sense that in another culture, life seems to proceed at either a slower or faster pace. Knowing how time is regulated, divided, and perceived can provide valuable insights into individuals and their culture.
The American orientation toward the future might be demonstrated by ______.
A．the presence of religious institutions
B．the preference for "old-fashioned" parents
C．the limited role of tradition
D．the presence of folk singers in church services

The Impossibility of Rapid Energy Transitions
[ A ] Politicians are fond of promising rapid energy transitions．Whether it is a transition from imported to domestic oil or from coal-powered electricity production to natural-gas power plants， politicians love to talk big．Unfortunately for them （and often the taxpayers）， our energy systems are a bit like an aircraft carrier: they are unbelievably expensive， they are built to last for a very long time， they have a huge amount of inertia （meaning it takes a lot of energy to set them moving ）， and they have a lot of momentum once they are set in motion．No matter how hard you try， you can"t turn something that large on a dime （10美分硬币 ）， or even a few thousand dimes．
[ B ] In physics， moving objects have two characteristics relevant to understanding the dynamics of energy systems: inertia and momentum．Inertia is the resistance of objects to efforts to change their state of motion．If you try to push a boulder （大圆石 ）， it pushes you back．Once you have started the boulder rolling， it develops momentum， which is defined by its mass and velocity．Momentum is said to be "conserved，" that is， once you build it up， it has to go somewhere．So a heavy object， like a football player moving at a high speed， has a lot of momentum-that is， once he is moving， it is hard to change his state of motion．If you want to change his course， you have only a few choices: you can stop him， transferring （possibly painfully） some of his kinetic energy （动能） to your own body， or you can approach alongside and slowly apply pressure to gradually alter his course．
[ C ] But there are other kinds of momentum as well．After all， we don"t speak only of objects or people as having momentum; we speak of entire systems having momentum．Whether it"s a sports team or a presidential campaign， everybody relishes having the big momentum， because it makes them harder to stop or change direction．
[ D ] One kind of momentum is technological momentum．When a technology is deployed， its impacts reach far beyond itself．Consider the incandescent （白炽灯的） bulb， an object currently hated by many environmentalists and energy-efficiency advocates．The incandescent light bulb， invented by Thomas Edison， which came to be the symbol of inspiration， has been developed into hundreds， if not thousands， of forms．Today， a visit to a lighting store reveals a stunning array of choices．There are standard-shaped bulbs， flame-shaped bulbs， colored globe-shaped bulbs， and more．It is quite easy， with all that choice， to change a light bulb．
[ E ] But the momentum of incandescent lighting does not stop there．All of those specialized bulbs ledto the building of specialized light fixtures， from the desk lamp you study by， to the ugly but beloved hand-painted Chinese lamp you inherited from your grandmother， to the ceiling fixture in your closet， to the light in your oven or refrigerator， and to the light that the dentist points at you．It is easy to change a light bulb， sure， but it is harder to change the bulb and its fixture．
[ F ] And there is more to the story， because not only are the devices that house incandescent bulbs shaped to their underlying characteristics， but rooms and entire buildings have been designed in accordance with how incandescent lighting reflects off walls and windows．
[ G ] As lighting expert Howard Brandston points out， “ Generally， there are no bad light sources， only bad applications．" There are some very commendable characteristics of the CFL [ compact fluorescent （荧光的） light bulb ]， yet the selection of any light source remains inseparable from the luminaire （照明装置 ） that houses it， along with the space in which both are installed， and lighting requirements that need to be satisfied．The lamp， the fixture， and the room， all three must work in concert for the true benefits of end-users．If the CFL should be used for lighting a particular space， or an object within that space， the fixture must be designed to work with that lamp， and that fixture with the room．It is a symbiotic （共生的 ） relationship．A CFL cannot be simply installed in an incandescent fixture and then expected to produce a visual appearance that is more than washed out， foggy， and dim．The whole fixture must be replaced-light source and luminaire-and this is never an inexpensive proposition．
[ H ] And Brandston knows a thing or two about lighting， being the man who illuminated the Statue of Liberty．
[ I ]Another type of momentum we have to think about when planning for changes in our energy systems is labor-pool momentum．It is one thing to say that we are going to shift 30 percent of our electricity supply from， say， coal to nuclear power in 20 years．But it is another thing to have a supply of trained talent that could let you carry out this promise．That is because the engineers，designers， regulators， operators， and all of the other skilled people needed for the new energy industry are specialists who have to be trained first （or retrained， if they are the ones being laid off in some related industry）， and education， like any other complicated endeavor， takes time．And not only do our prospective new energy workers have to be trained， they have to be trained in the right sequence．One needs the designers， and perhaps the regulators， before the builders and operators， and each group of workers in training has to know there is work waiting beyond graduation．In some cases， colleges and universities might have to change their training programs，
adding another layer of difficulty．
[ J ] By far the biggest type of momentum that comes into play when it comes to changing our energy systems is economic momentum．The major components of our energy systems， such as fuel production， refining， electrical generation and distribution， are costly installations that have lengthy life spans．They have to operate for long periods of time before the costs of development have been recovered．When investors put up money to build， say， a nuclear power plant， they expect to earn that money back over the planned life of the plant， which is typically between 40and 60 years．Some coal power plants in the United States have operated for more than 70 years!
The oldest continuously operated commercial hydro-electric plant in the United States is on New York"s Hudson River， and it went into commercial service in 1898．
[ K ] As Vaclav Smil points out， "All the forecasts， plans， and anticipations cited above have failed so miserably because their authors and promoters thought the transitions they hoped to implement would proceed unlike all previous energy transitions， and that their progress could be accelerated in an unprecedented manner．"
[ L ] When you hear people speaking of making a rapid transition toward any type of energy， whether it is a switch from coal to nuclear power， or a switch from gasoline-powered cars to electric cars， or even a switch．from an incandescent to a fluorescent light， understanding energy system inertia and momentum can help you decide whether their plans are feasible．
Not only moving objects and people but all systems have momentum．

The word "television" can literally be interpreted as sight from a distance. Very simply put, it works in this way: through a complete system of electronics, television provides the capability of converting an image into electronic impulses, which can be sent through a wire or cable. These impulses, when fed into a receiver (television set), can then be electronically reconstructed into that same image.
Television is more than just an electronics system, however. It is a means of expression, as well as a vehicle for communication, and as such becomes a powerful tool for reaching other human beings.
The field of television can be divided into two types. First, there is broadcast television, which reaches the masses through broad-based airwave transmission of television signals. Second, there is non-broadcast television, which provides for the needs of individuals or specific interest groups through controlled transmission techniques.
Traditionally, television has been a medium of the masses. It has been with us for about thirty- seven years in a form. similar to what exists today. During those years, it has been controlled mostly by the broadcast networks, ABC, NBC and CBS, who have been the major suppliers of news, information, and entertainment. These giants of broadcasting have actually not only shaped television as a source of entertainment, but placed our role in this active medium as the passive viewer.
What is the topic of the passage？
A．The role of television in today's society.
B．The marriage of broadcasting giants.
C．Recent changes in modern technology.
D．The content of broadcast television programs.

Text 3
Under certain circumstances, the human body must cope with gases at greater-than-normal atmospheric pressure. For example, gas pressures increase rapidly during a dive made with scuba gear because the breathing equipment allows divers to stay underwater longer and dive deeper.
The pressure exerted on the human body increases by 1 atmosphere for every 10 meters of depth in seawater, so that at 30 meters in seawater a diver is exposed to a pressure of about 4 atmospheres. The pressure of the gases being breathed must equal the external pressure applied to the body, otherwise breathing is very difficult. Therefore all of the gases in the air breathed by a scuba diver at 40 meters are present at five times their usual pressure. Nitrogen, which composes 80 per cent of the air we breathe, usually causes a balmy feeling of well-being at this pressure. At a depth of 5 atmospheres, nitrogen causes symptoms resembling alcohol intoxication, known as nitrogen narcosis. Nitrogen narcosis apparently results from a direct effect on the brain of the large amounts of nitrogen cause under these pressurized helium does not exert a similar narcotic effect.
As a scuba diver descends, the pressure of nitrogen in the lungs increases. Nitrogen then diffuses from the lungs to the blood, and from the blood to body tissues. The reverse occurs when the diver surfaces; the nitrogen pressure in the lungs falls and the nitrogen diffuses from the tissues into the blood, and from the blood into the lungs. If the return to the surface is too rapid, nitrogen in the tissues and blood cannot diffuse out rapidly enough and nitrogen bubbles are formed. They can cause severe pains, particularly around the joints.
Another complication may result if the breath is held during ascent. During ascent from a depth of 10 meters, the volume of air in the lungs will double because the air pressure at the surface is only half of what it was at 10 meters. This change in volume may cause the lungs to distend and even rupture. This condition is called air embolism. To avoid this event, a diver must ascend slowly, never at a rate exceeding the rise of the exhaled air bubbles, and must exhale during as- cent.
31. What does the passage mainly discuss？
A) The equipment divers use.
B) The effects of pressure on gases in the human body.
C) How to prepare for a deep dive.
D) The symptoms of nitrogen bubbles in the bloodstream.
"The social dynamics of care are changing," says John Gomez, vice president of Eclipsys, a medical information technology company. Most patients might not yet be willing to share their latest CT scan images over Facebook, he notes, but many parents post their babies' ultrasound images, and countless patients nowadays use social networking sites to share information about conditions, treatments and doctors.
With greater access to individualized health information-whether that is through a formal electronic medical record, a self-created personal health record or a quick instant-messaging session with a physician—the traditional roles of doctors and patients are undergoing a rapid transition.
"For as long as we've known, health care has been I go to the physician, and they tell me what to do, and I do it,'" says Nitu Kashyap, a physician and research fellow at the Yale Center for Medical Informatics. Soon more patients will be arriving at a hospital or doctor's office,having reviewed their own record, latest test results and recommended articles about their health concerns. And even more individuals will be able to skip that visit altogether, instead sending a text message or e-mail to their care provider or consulting a personal health record or smart phone application to answer their questions.
These changes will be strengthened by the nationwide shift to electronic medical records,which has already began. Although the majority of U.S. hospitals and doctors' offices are still struggling to start the changeover, many patients already have electronic medical records, and some even have partial access to them. The My Chart program, in use at Cleveland Clinic, the University of Texas Southwestern Medical Center at Dallas and other facilities, is a Web portal (门户)through which patients can see basic medical information as well as some test results.
Medical data is getting a new digital life, and it is jump-starting a "fundamental change in how care is provided," Gomez says.
Which of the following is the best title for this passage？
A．The Future of Your Medical Data.
B．Challenges Against Doctors and Hospitals.
C．Benefits of the U. S. Health Care Reform.
D．How to Access and Share Your Health Information.
