Historians may well look back on the 1980s in the United States as a time of rising affluence side by side with rising poverty. The growth in affluence is attributable to an increase in professional and technical jobs, along with more two career couples whose combined incomes provide a" comfortable living". Yet simultaneously, the nation’ s poverty rate rose between 1973 and 1983 from 11.1 percent of the population to 15.2, or by well over a third. Although the poverty rate declined somewhat after 1983, it was still held at 13.5 percent in 1987, comprising a population of 32:5 million Americans.
The definition of poverty is a matter of debate. In 1795, a group of English magistrates decided that a minimum in come should be "the cost of a gallon loaf of bread, multiplied by three, plus an allowance for each dependent". Today the Census Bureau defines the threshold of poverty in the United States as the minimum amount of money that families need to purchase a nutritionally adequate diet, assuming they use one third of their income for food. Using this definition, roughly half the American population was poor in the aftermath of the Great Depression of the 1930s. By 1950, the proportion of the poor had fallen to 30 percent and by 1964, to 20 percent. With the adoption of the Johnson administration ’ s antipoverty programs, the poverty rate dropped to 12 percent in 1969. But since then, it has stopped falling. Liberals contend that the poverty line is too low because it fails to take into account changes in the standard of living.
Conservatives say that it is too high because the poor receive other forms of public assistance, including food stamps, public housing subsidies, and health care.

How many people are there in the United States in 1987（）

A:259 million. B:117 million. C:175 million. D:240 million.

The United States is the United Nations’ biggest deadbeat. Conservatives in Congress, led by Senator Jessie Helms, stopped Washington from paying its dues until the UN reduced its assessment and made other changes. Now, thanks to the hard work of Richard Holbrooke, America’s UN representative, and his staff, the UN has agreed to trim the U. S. share of financial burdens for the UN general budget and for peacekeeping. Mr. Helms, who has praised the deal, should release the dues he has been holding hostage— $582 million of the $1.3 billion the UN says it is owed.
The new formula would reduce the U. S. contribution to the general UN budget to 22% from the current level of 25%—a symbolic difference of only $34 million a year. Washington, which has been paying just over 30% of the peacekeeping budget, would now pay 27%—a difference of $80 million to $120 million a year—and that percentage will drop further. While poor countries would not pay more, the dues of other wealthy nations would rise under the new system.
The agreement would probably not have been reached without the intervention of the media magnate Ted Turner, who is already contributing $1 billion to UN programs over 10 years. Mr. Turner gave $34 million to cover the one-year gap during which other nations prepare to raise their contributions. His offer should embarrass Congress, which forced diplomats to waste their influence at the UN in months of negotiations to save a sum that is modest by federal budget standards.
U. S. debts reduced the UN’s ability to reimburse nations that contributed peacekeepers to UN missions worldwide. Pakistan, Bangladesh, Jordan and other poor countries essentially made up for the absence of U. S. financial support. Since Washington benefits from peacekeepers, who damp down conflicts without U. S. troops, it should not be discouraging nations from sending them.
Washington’s natural allies at the UN were concerned that the U. S. wanted influence without meeting its treaty obligations. Some of them withheld support for U. S. proposals. Mr. Helms should also end his hold on an additional $244 million in back dues, whose release he has conditioned on a reduction in U. S. dues for specialized UN agencies such as Unicef and the UN refugee organization. These agencies need full support. A switch by Mr. Helms would help the incoming Bush administration, which would reap the benefits of the restoration of America’s full influence at the United Nations.
The new formula has adjusted the assessment and will save the U. S. government at least ______ a year.

A:$114 million B:$154 million C:$200 million D:$234 million

At current online-ed rates, it is almost impossible for web publishers that create their own content to make money—just ask any of the two dozen, from Z.com to eCountries that have gone bust in the past month alone. The mason for the bloodbath is simple: advertisers are not willing m pay enough for web ads to support the cost of displaying them.
To see why, consider a credit-card firm that wants to find customers online. Say it runs a campaign to display its banner ad to 2 million viewers. Using industry averages, one out of every 200 viewers can be expected to click on the ad: one out of every 100 of those will actually sign up for a credit card. Thus, the campaign would yield 100 new customers. Offline. the firm pays about $150 for each customer it acquires, through anything from direct mail to television ads. Using the same rate, it would therefore be willing to pay $15.000 for those 2 million online-ad views, or a cost-per-thousand- views (CPM) rate of $7.50.
Now consider the economics of the website that is running those ads. It probably does not have its own ad sales team, so it is getting those credit-card ads from an advertising network such as DoubleClick. The network takes half the revenues, leaving the site with a CPM of $3.75. Imagine that the site is very successful, say among the top few hundred on the web. If so, it may be able to generate 10m page views ’a month. At $3.75 per thousand views, that means revenue of $37,500 a month. Take out hardware, software and bandwidth costs, and enough might be left to support two employees or so.
This grim picture can be improved by selling more than one ad per page. but such clutter often comes at the cost of a lower rate of "click-throughs" and, eventually, even lower CPMs. The site can try to charge higher CPMs by providing more information about viewer demographics, to help advertisers target their ads, or by claiming that it has a sign that may justify a fee for brand-building advertisers. But advertisers are skeptical.
The biggest web portals get their content almost for free—a mixture of material from other-sites and content created by viewers—and attract so much traffic that they can support huge organizations on low CPMs. But for most smaller websites, there is no way out. Those that cannot find revenue sources beyond advertising will either go bust or be forced to admit that their site is a non-profit enterprise. If truth-in-advertising rules were enforced, most dotcoms would be dotorgs.
Using industry averages, if 400 viewers can be expected to sign up a credit ,card, how much viewers will actually see the ad

A:2 million B:4 million C:16 million D:8 million

It is estimated that some seven hundred million people—about half the world’s adult population—are unable to read or write, and there are probably two hundred and fifty mil lion more whose level of achievement in reading is so small that it can hardly be thought of as literacy.
Recently the attack on illiteracy has been speeded up. A world plan has been made by a committee of UNESCO experts in Paris as part of the United Nations Development Decade, and an international conference on the subject has also been held. UNESCO says that functional literacy is the aim. People must have the ability to read notices, newspapers, timetables, letters, price-lists；to keep simple records and accounts and to fill in forms.
The major areas of illiteracy are in Asia, Africa, and Central and South America. In Africa there are at least one hundred million illiterates, comprising eighty to eighty-five percent of the total population. In Europe the figure is about twenty-four million, most of whom are in Southern Europe. Britain has about seven hundred thousand.

From the Passage, we learn that the total population of Africa is approximately （）

A:seven hundred million B:one hundred and twenty-five million C:eight or eight point five thousand million D:one hundred million

Paris is the capital of the European nation of France. It is also one of the most beautiful and most famous cities in the world.
Paris is called the City of Light. It is also an international fashion center. What stylish women are wearing in Paris will be worn by women all over the world. Paris is also a famous world center of education. For instance, it is the headquarters of UNESCO, the United Nations Educational, Scientific, and Cultural Organization.
The Seine River divides the city into two parts. Thirty-two bridges cross this scenic river. The oldest and perhaps most well known is the Pont Neuf, which was built in the sixteenth century. The Sorbonne, a famous university, is located on the Left Bank(south side) of the river. The beautiful white church Sacre Coeur lies on top of the hill called Montmartre on the Right Bank(north side) of the Seine.
There are many other famous places in Paris, such as the famous museum the Louvre as well as the Cathedral of Notre Dame. However, the most famous landmark in this city must be the Eiffel Tower.
Paris is named after a group of people called the Parisii. They built a small village on an island in the middle of the Seine River about two thousand years ago. This island, called the Ile de la Cite, is where Notre Dame is located. Today around eight million people live in the Paris area.
The population in the Paris area is around ______.

A:two million B:eight million C:sixteen million D:eighteen million

Many of the world’s pollution problems have been caused by the crowding of large groups of people into the cities. Supply for the needs of the people leads to further pollution by industry. If the rapid increase in human population continues at the present rate, there may be much greater harm. Some scientists speak of the increase in numbers of people as "population pollution".
About 2,000 years ago, the world population was probably 250 million. It reached a billion in 1850. By 1930, the population was two billion. It was three and a half billion in 1988. It is expected to double by the year 2000. If the population continues to grow at the same rate, there would be 25 billion people in the world a hundred years from now!
Man has been using the earth’s resources more and more rapidly over the years. Some of them are almost gone. Now many people believe that man’s greatest problem is how to control population, in time to come, if the present rate of increase continues. Already there is overcrowding in the cities and hunger in some countries. Can man’s rate of increase continue Many people believe that human survival in the future depends on the answer to this question.
In the year 2000, it is expected that world population will be ______.

A:350 million B:25,000 million C:4,000 million D:7,000 million
