Mostly, this explosive growth has occurred democratically. The online penetration and computer ownership increases extend across all the demographic levels-by race, geography, income, and education.
We view these trends as favorable without the slightest question because we clearly see computer technology as empowering. In fact, personal growth and a prosperous U.S. economy are considered to be the long-range rewards of individual and collective technological power.
Now for the not-so-good news. The government's analysis spells out so-called digital divide. That is, the digital explosion is not booming at the same pace for everyone. Yes, it is true that we are all plugged in to a much greater degree than any of us have been in the past. But some of us are more plugged in than others and are getting plugged in far more rapidly. And this gap is widening even as the pace of the information age accelerates through society.
Computer ownership and Internet access are highly classified along lines of wealth, race, education, and geography. The data indicates that computer ownership and online access are growing more rapidly among the most prosperous and well educated: essentially, wealthy white people with high school and college diplomas and who are part of stable, two-parent households.
The highest income bracket households, those earning more than $75,000 annually, are 20 times as likely to have access to the Internet as households at the lowest income levels, under $10, 000 annually. The computer penetration rate at the high-income level is an amazing 76.56 percent, compared with 8 percent at the bottom end of the scale.
Technology access differs widely by educational level. College graduates are 16 times as likely to be Internet surfers at home as are those with only elementary-school education. If you look at the differences between these groups in rural areas, the gap widens to a twenty-six-fold advantage for the college-educated.
From the time of the last study, the information access gap grew by 29 percent between the highest and lowest income groups, and by 25 percent between the highest and lowest education levels.
In the long run, participation in the information age may not be a zero sum game, where if some groups win, others must lose. Eventually, as the technology matures we are likely to see penetration levels approach all groups equally. This was true for telephone access and television ownership, but eventually can be cold comfort in an era when tomorrow is rapidly different from today and unrecognizable compared with yesterday.
How many U. S. households have linked to Internet today？
A．More than 25 percent.
B．By 29 percent.
C．More than 42 percent.
D．More than 50 percent.
appearing on the screen. The rule was the more money you (), the better player you were, given a total of 100 clicks. Every time the students opened a door by () on it, they would use up one click but wouldn't get any money. However, each () click on that door would earn a () sum of money, with one door always () more money than the others. The important part of the rule was each door switch, though having no cash (), would also use up one of the 100 clicks. Therefore, the winning () was to quickly check all the doors and keep clicking on the one with the seemingly highest ().

Hair Co manufactures three types of electrical goods for hair: curlers (C), straightening irons (S) and dryers (D.) The budgeted sales prices and volumes for the next year are as follows:
Each product is made using a different mix of the same materials and labour. Product S also uses new revolutionary technology for which the company obtained a ten-year patent two years ago. The budgeted sales volumes for all the products have been calculated by adding 10% to last year’s sales.
The standard cost card for each product is shown below.
Both skilled and unskilled labour costs are variable.
The general fixed overheads are expected to be $640,000 for the next year.
Required:
(a) Calculate the weighted average contribution to sales ratio for Hair Co.
Note: round all workings to 2 decimal places. (6 marks)
(b) Calculate the total break-even sales revenue for the next year for Hair Co.
Note: round all workings to 2 decimal places. (2 marks)
(c) Using the graph paper provided, draw a multi-product profit-volume (PV) chart showing clearly the profit/loss lines assuming:
(i) you are able to sell the products in order of the ones with the highest ranking contribution to sales ratios first; and
(ii) you sell the products in a constant mix.
Note: only one graph is required. (9 marks)
(d) Briefly comment on your findings in (c). (3 marks)
The Transformation consists of all the changes that are occurring m human life due to advancing technology. For thousands of years such progress occurred slowly. Now, everything is changing so fast that you may find yourself wondering where all this progress is really leading.
Nobody knows what all these changes really will mean in the long run. But this mysterious Transformation is the biggest story of all time. It is the story of the human race itself.
Some people worry about what will happen when the deposits of petroleum are gone, but already researchers are finding all kinds of new ways to obtain energy. Someday, solar power collected by satellites circling the earth of fission power manufactured by mankind may give us all the energy we need for an expanding civilization. Space exploration promises to open up many new territories for human settlement, as well as leading to the harvest of mineral resources like the asteroids.
Scientific research continues to open up previously undreamed-of possibilities. Fifty years ago, few people could even imagine things like computers, lasers, and holography. Today, a host of newly emerging technologies such as artificial intelligence and genetic engineering are opening up all kinds of new paths for technologists.
Like it or not, our advancing technology has made us masters of the earth. We not only dominate all the other animals, but we are reshaping the world's plant life and even its soil and rocks, its waters and surrounding air. Mountains are being dug up to provide minerals and stone for buildings. The very ground under our feet is washing away as we chop down the forests, plow up the fields, and excavate foundations for our buildings.
Human junk is cluttering up not only the land but even the bottom of the sea. And so many chemicals are being released into the air by human activities that scientists worry that the entire globe may warm, causing the polar icecaps to melt and ocean waters to flood vast areas of the land.
During the twentieth century, advancing technology has enabled man to reach thousands of feet into the ocean depths and to climb the highest mountains. Mount Everest, the highest mountain of all, resisted all climbers until the 1950's. Now man is reaching beyond Earth to the moon, Mars, and the stars.
No one knows what the Great Transformation means or where it will ultimately lead. But one thing is sure: Human life 50 years from now will be very different from what it is today.
It's also worth noting that our wondrous technology is posing an increasingly insistent question: When we can do so many things, how can we possibly decide what we really should do？ When humans were relatively powerless, they didn't have to make the choices they have to make today.
Technology gives us the power to build a magnificent new civilization—if we can just agree on what we want it to be. But today, there is little global agreement on goals and how we should achieve them.
So it remains to be seen what will happen as a result of our technology. Pessimists worry that we will use the technology eventually to blow ourselves up. But they have been saying that for decades, and so far we have escaped. Whether we will continue to do so remains unknown—but we can continue to hope.
The Great Transformation is caused by______.
A．artificial intelligence and genetic engineering
B．the shortage of natural resources
C．the development of practical science
D．unknown reasons
