Technology has come to the marketplace. In many U. S stores the cash【C1】______has been rep

laced by a computer that quickly and easily calculates the cost of items being bought.

Back in the early 1960s, when the laser【C2】______developed, it was viewed by some as a fascinating research tool; others called it a【C3】______toy. Since that time, the laser has proved to be an【C4】______of many uses. In fact, in many places it's becoming a part of【C5】______life. Take, for example, what's happening at some supermarkets. Food-shopping Americans are coming【C6】______with lasers and computers for the first time. But they're hardly【C7】______it, until they get to the checkout line. With scarcely a glance at the items, the clerk【C8】______them across a hole, where a special marking on each item is scanned by a low-powered laser【C9】______inside the machine, connected to a remote computer. It started a few years ago, when food processors【C10】______the time had come to put code markings on every one of their thousands of food products. This would make them【C11】______identifiable to a computer. The scanning laser beam was an【C12】______device for reading these markings, and so the Universal Product Code was born.

【C13】______every package today, every can and bottle, has these unique symbols.【C14】______is the time-consuming stamping of prices on each item. Prices are shown【C15】______the shelf.

This mew technology promises to【C16】______food products moving smoothly on and off supermarket shelves, which will help keep overhead down and prices【C17】______At the end of each business day, the remotely-located computer gives the store manager a total picture of the day's【C18】______--what the needs to restock,【C19】______, and what he can mark down and put on sale.

It is not, by no means, the worlds oldest company. There are 【M1】______ Japanese hotels d

ated back to the 8th century, German breweries that 【M2】______ hail from the 11th and an Italian bank with roots in the 15th. What is unusual about IBM, which celebrates its 100th birthday this week, is that it has been so successful and so long in the fast-moving field of 【M3】______ technology. How has it done it？ IBMs secret is that it is built around an idea that transcends any special product or technology. Its strategy is to package technology 【M4】______ for use by businesses.

The Sydney Opera House is the mother and father of all modern landmark buildings. Although

its architect was forced to resign and it was never properly finished inside, the opera house has come to define not only a city, but also an entire nation and continent. The Sydney Opera House was meant to look like a giant sailing ship. But you may bring whatever interpretation you would to it.// Since its opening in 1973, the Sydney Opera House has been host to many of the most memorable, world-class artistic performances. However, as time goes by, modifications are required to meet the needs and technology of the day, without, of course, losing its architectural integrity. The New South Whales government has agreed to provide $69. 3 million for several projects to improve the facilities and environment for performing arts companies, patrons and visitors.//

第一篇

The Hammersmith Hospital in West London, home of the Royal Post-graduate Medical School has been the scene(发生地点) of many innovations in medicine. It is now home(中心地,根据地) to the most expensive and ambitious medical technology project ever in Britain, which this year will make the Hammersmith the world's first fully digital hospital. The paper-free office brought about by computerization and modern information technology is familiar to(为……所熟悉) many office workers today. It has taken longer for the same technology to be applied to medical imaging(医学影像学), because of the immense computing power and high cost o the equipment required.

But now the Hammersmith is becoming the first hospital in which all imaging data-- X-rays, ultrasonic ,CT and MRI images--are stored not on cumbersome, inflammable films but as digital data on optical discs. The first consequence of this can be seen in the air-conditioned computer room in the new building, where two compact(坚实的,结实的) cabinets each about as tall as a man and 0.6m wide are ready to store every X-ray and scan made at the Hammersmith in the next 16 years on optical discs(光盘).

Space saving is the most obvious but not the most important advantage of the digital h6spital. A consultant conducting a clinic with a workstation linked by fibre optics(光纤) to the data store has no need of cumbersome trolleys loaded with patients' X-rays. The new technology considerably reduces the exposure to ionizing (电离的) radiation needed to get pictures doctors need, corresponding to reducing the slight but inevitable health risk that come with repeated X-rays.

X-rays record their images on fluorescent(荧光的) plates, lasers read off and store the data and the plates are wiped clean to use again. This requires less radiation than conventional(常规的) imaging. The ability to enhance imaging also reduces the need for extra exposures.

Another advantage is that any stored image can be sent to any of the hospital's 138 workstations in four seconds(soon that will come down(降落) to two seconds). Soon it will be possible to send it direct to other hospitals, or to computer screens in GP's(全科医生) clinics.

PACS(图像存档通讯系统) is the most expensive single medical technology project ever funded in UK. Most of the money has come from the Department of Health, which has realized that it will benefit patients at the Hammersmith Hospital and those referred from elsewhere, in terms of(按照) better, quicker and safer diagnosis and treatment.

Another technique uses radio a belled(用放射性同位素示踪的) white blood cells to guide doctors to the sites of hidden abscesses(脓肿) or other trouble spots.

In the most innovative technique of all, interventional(干预的,介入的) radiology, doctors use tiny instruments at the ends of fine catheters(导管), inserted deep into the body under local anaesthetic, to perform. a growing amount of microsurgery, viewed by surgeons—and patients if appropriate—in extremely clear detail. Every scrap(碎片,段) of unwanted image is electronically edited off the screen by the computer.

The Hammersmith Hospital is also pioneering interventional radiography, in which doctor carry out microsurgery at the same time as they image the patients' organs in minute detail. The blocking or unblocking of arteries to prevent damage due to bleeding or thrombosis(血栓形成) is among the conditions now being treated in this way.

The Hammersmith Hospital______.

A. is located in the west of London

B. takes the lead in medical innovations

C. has more advanced and modern medical technology than any other hospital in Britain.

D. all of the above

Technology in Our Modern Lives

Throughout the 20 century, from 1900 onwards, people have dreamt of the technological advances that the advent of the new millennium(千禧年) would bring. (46) The year 2000 has now come and gone and while flying cars are still left to the realm of the imagination, the infusion(注入) of technology into all areas of life has indeed become a reality.

Leading the technological change is the ever-present computer. In the United States, fully one-half of all households are connected to the Internet, and the pace is rapidly increasing, with 700 more households becoming connected every hour. The computer industry has produced over one million new jobs, spurring rapid and unprecedented(前所未有的)growth in economic output and prosperity. (47) In 1999, 27% of companies monitored(监视) their employees' email activities in some form, and by 2000 the number had grown to 38.2%, indicating the growing importance of electronic communication in business. The younger generations are becoming indoctrinated(被灌输) into the computer culture as well: In the United States alone, 424 million educational CD-ROMs were purchased, making computers and other forms of high-technology integral elements in the education system.

(48) By 1988 the figure had grown to 40% of total business investment expenditures, and the figures is only expected to grow in the future. The technological revolution does not end with computers, however. (49) For better or for worse, technology takes part in every aspect of our lives, from the moment we wake up to the time we go to bed. Whether we like it or not, we have come to rely on its convenience, to the point of almost for getting that it's even there. (50) Every second, 2, 700 photos are taken with the latest cameras, and 80% of those snapshots(快照) are taken by people on vacation. No matter where one goes, no matter how far from urban centers, technology has become a basic element of everyday life. Flying cars or no flying cars, the future is here, and technology is the name of the game.

A. The growing effects of computers on business go even deeper, however.

B. They envisioned a world of flying cars, where high-tech gadgets (小巧的装置) were a part of every aspect of life.

C. In 1990, 20% of the average company's business investment expenditures consisted of computers and other high-tech equipment.

D. The full impact and implication of high technology in daily life is yet to be determined.

E. One cannot escape the far-reaching grip of technology even when on vacation.

F. It is estimated that by the year 2005, 1.6 billion mobile phones will be in use, keeping people connected to one another all the time no matter where they are.

This month is expected to see that seminal（有创意的)moment when digital cinema will outstr

This month is expected to see that seminal(有创意的)moment when digital cinema will outstrip the 35 mm technology that has been the dominant projection format in movie theatres for over 120 years. In 2009, digital accounted for only 15% of global screens. But the movie Avatar changed all that. 3D movies required digital, and Avatars phenomenal success with 3D pushed cinemas to adopt digital screens. IMS Screen Digest Cinema Intelligence Service estimates that by the end of 2012, digital will account for 63% of screens, and by 2015, 83 %. A majority of those screens will be based on Texas Instruments digital light processing(DLP)technology, a technology that uses millions of tiny mirrors on a tiny chip, each of them capable of moving thousands of times per second to create a digital image. That same technology today is also beginning to be used in cellphones and digital cameras to project images in those devices onto ordinary surfaces. That will be a bigger opportunity, says Kent Novak, Texas Instruments senior VP for DLP products, who was in Bangalore recently. Cinemas are moving rapidly to digital screens. Why？ The first digital movie was premiered(首演)in 1999. Initially it was thought moving to digital would give better picture quality and cost savings, but it took many years for a few systems to get deployed. And then Avatar happened. That was really the tipping point. In 2008, 15 3D movies were released; in 2009, it was close to 50. Theatres were able to get more people and get a higher price for the ticket, so it became a significant invenue generator. We have seen more conversion of film to digital in the last two years than in the previous ten. You are now bringing the technology to smaller devices. We are moving to put these chips into cellphones, digital still cameras, camcorders, laptop accessories, tablets, docking stations, media players. Weve been hearing of pico(handheld)projectors for some time now. But we dont really see products in the market. The technology has only recently reached a tipping point in terms of lighting efficiency and total brightness. Three years ago, 1 watt of power could get the brightness measurement of about 5 lumens. Today that 1 watt can give 20 lumens(making the projected image brighter). We designed the chip to be more efficient. Also, the industry driver for efficiency is LED. The amount of investment going into LED is enormous. As technology has improved, volumes have gone up, and cost has come down. Micromax and Spice in India have put projection even in some of their feature phones; Samsung has put projection on some of their phones. Nikon has DLP embedded in some of their digital still cameras, Sony has them in camcorders. What are the use cases that you see？ You can use your phone to show video clips, pictures, power point presentations, and make it a shared experience. India has been more progressive in adopting the technology because feature phones are a phone during the day and become the primary entertainment source in the evenings. India also has mobile TV phones with pre loaded Bollywood movies that can be projected out of the phone.

The word "outstrip" in the first paragraph most possibly mean "______. "

A．take off

B．outlive

C．surround

D．surpass

Police in the popular resort city Virginia Beach recently began operating video surveillan

ce cameras with controversial face recognition technology. Virginia Beach and Tampa in Florida two cities in the United States acquired the technology, which cost them $ 197, 000.” “Before we switched it on, we went through an extensive public education process with hearings and the involvement of citizen groups and minority groups, who helped write the policies we are using, " said deputy police chief Greg Mullen. A citizens' auditing committee has the right to perform. unannounced spot checks on police headquarters to make sure the technology is not being misused.

Three of the city's 13 cameras are linked full time to the face recognition system, though the others can be activited as needed. The database of wanted people is updated every day. So far, the system has failed to produce a single arrest, though it has generated a few false alarms. It works by analyzing faces based on a series of measurements, such as the distance from the tip of the nose to the chin or the space between the eyes. Critics say it is highly inaccurate and can be easily fooled. Mullen, who sees the system eventually being linked to the databases of other city, state and federal law enforcement agencies to track criticals and suspected terrorists, said, "The system doesn't look at skin color or your hair or your gender. It takes human prejudices out of the equation. "

"This technology has little or no effect on the crime rate but it does have an effect on people's behavior. People feel cowed, " said Bruce Steinhardt, who directs the technology. Despite the fact that tests have shown faces recognition only works in around 30% cases, the ACLU is alarmed that the technology may soon spread to airports. The organization also fears it could potentially be used to monitor individual's political activities to harass law-abiding citizens.

" This kind of surveillance should be subject to the same procedures as wiretaps. Law enforcement agencies should justify why they need it and it should be tightly limited, otherwise it will soon become a tool of social control, " said Mihir Kshisagar of the Electronic Information Privacy Center. Nor does such criticism come exclusively from the political left. Lawyer John Whitehead, founder of the conservative Rutherford Institute, wrote in an editorial that the technology threatened the right of each U. S. citizen to participate in society. "After all, that is exactly what constant surveillance is—the ultimate implied threat of coercion, " he wrote.

What does Mullen's statement in Paragraph 1 indicate？

A．Police is confident in using the technology.

B．Police has made preparation for the use of the technology.

C．Citizens have rights over managing the technology.

D．Police has gone through public education process.
