更多“The combined total population …”相关的问题
Though the size of the workforce relies greatly on the size of the total population, there are several other aspects which also affect it. The age distribution of the total population has a very marked effect on the available workforce. If the population bas a high proportion of very young people or of those too old to work, then the available workforce would be lower than if there were an evenly spread age distribution. If the population grows rapidly from natural in crease, i. e. the number of births greatly exceeds the number of deaths, then as a total population increases the proportion in the workforce declines.
Sometimes a population is described as aging, which means that the birth rate is either falling or growing very slowly, and as people retire from the workforce there are unadequate numbers of young people entering it to take place of those who are leaving it. The population is top-heavy with older people. So the percentage of the population in the workforce declines when there is either a rapid increase in births or a falling birth rate.
The age distribution of the population has several important influences on the economy. If the population is aging and there is an increase in the number of people retiring without a corresponding increase in the number entering the workforce, this raises the problem of the ability of the economy to provide a reasonable level of social services to the retired group. If the aged are to be cared for in special homes or hotels, finance must be available for that purpose. If the size of the workforce is small relative to the total population, then the government tax receipts are relatively low and either the government has less money available to it or the workforce members have to be taxed more heavily.
Labor force is composed of ______.
A．people who are available to work and earn income
B．self-employed people only
C．only those who are looking for an employment
D．only the employees

Labor force is defined as being the total number of people who are available to work and earn income. This definition includes everyone who is employed or seeking paid employment, so it includes employees and the self-employed. Labor is one of the country's resources which can be combined with other resources to produce the goods and services required by the community.

very complex. Generally speaking, the Accounts Department is __1__ for calculations of pay, while the Personnel Department is interested in discussions with the employees about pay.
If a firm wants to __2__ a new wage and salary structure, it is essential that the firm should decide on a __3__ of job evaluation and ways of measuring the performance of its employees. In order to be __4__, that new pay structure will need agreement between Trade Unions and employers. In job evaluation, all of the requirements of each job are defined in a detailed job description. Each of thsoe requirements is given a value, usually in "points", which are __5__ together to give a total value for the job. For middle and higher management, a special method is used to evaluate managers on their knowledge of the job, their responsibility, and their __6__ to solve problems. Because of the difficulty in measuring management work, however, job grades for managers are often decided without __7__ to an evaluation system based on points.
In attempting to design a pay system, the Personnel Department should __8__ the value of each job with these in the job market. __9__, payment for a job should vary with any differences in the way that the job is performed. Where it is simple to measure the work done, as in the works done with hands, monetary encouragement schemes are often chosen, for __10__ workers, where measurement is difficult, methods of additional payments are employed.

Japanese investment in the region is expected to increase in the future
A．to seventy-five per cent of japan's total investment.
B．by one hundred and fifty percent.
C．to ninety percent of the Thai auto market.
Even more troubling than the increasing number of inhabitants are the projections of where they will be concentrated. The study by Rafael M. Solos, executive director of the U. N. Fund for Population Activities, notes that by the year 2000:
Nearly 80 percent of all people will live in less developed countries, many hard pressed to support their present populations. That compares with 70 percent today.
In many of these Third World lands metropolises (大城市) will become centers of concentrated urban poverty because of a flood of migration from rural areas.
The bulging(膨胀的) centers mainly in Asia and Latin America, will increasingly become fertile fields for social unrest. More young residents of the urban clusters(一群) will be better educated, unemployed and demanding of a better lifestyle.
To slow the rush to urban centers, countries will have to vastly expand opportunities in the country side, the study suggests. Solos says: "The solution to the urban problem lies as much in the rural areas as in the cities themselves."
Worldwide, the numer of large cities ,will multiply. Now 26 cities have 5 million or more residents each and a combined population of 252 million. By the end of the decade, the number will escalate to 60. with an estimated total of almost 650 million people.
In the last paragraph, the word "escalate" means ______.
A．decrease
B．increase
C．go down
D．decline
Ways to Create Colors in a Photograph
There are two ways to create colors in a photograph．One method, called additive,startswith three basic colors and adds them together to produce some other color．Thesecond method, called subtractive, starts with white light (a mixture of all colors in the spectrum(光谱))and, by taking away some or all other colors, leaves the one desired.
In the additive method, separate colored lights combine to produce various other colors．The three additive primary colors are green, red and blue (each providing about one-third of the wavelengths in the total spectrum)． Mixed in varying proportions, they can produce all colors．Green and red light mix to produce yellow； red and blue light mix to produce magenta (a purplish pink) ；green and blue mix to produce cyan (a bluish green).When equal parts of all three of these primary-colored beams of light overlap(重叠), the mixture appears white to the eye.
In the subtractive process colors are produced when dye (染料)absorbs some wavelengths and so passes on only part o{ the spectrum．The subtractive primaries are cyan,magenta and yellow； these primaries or dyes absorb red, green and blue wavelengths respectively, thus subtracting them from white light．These dye colors are the complementary colors to the three additive primaries of red, green and blue．Properly combined, the subtractive primaries can absorb all colors of light, producing black．But, mixed in varying proportions, they too can produce any color in the spectrum.
Whether a particular color is obtained by adding colored lights together or by subtracting some light from the total spectrum, the result looks the same to the eye．The additive process was employed for early color photography．But the subtractive method, while requiring complex chemical techniques, has turned out to be more practical and is the basis of all modern color films.
第 36 题 What does the passage mainly discuss？
A．Recent developments in camera technology.
B．How to make white light.
C．The additive and subtractive methods of producing color.
D．The discovery of the spectrum.

D．The total yearly spending of the EEC on solar energy research amounted to almost 6 million dollars.
Think of FORTUNE's Global 500 as a candid family portrait, a statistical snapshot of the world's largest corporations assembled shoulder to shoulder, frozen in time. So it is that this year, in the waning light of the 20th century, our reunion photo captures an optimistic scene: a rosy business landscape populated by jolly corporate giants--healthy, happy, and fat. After stumbling amidst the economic turmoil of 1998, the companies of the Global 500 recovered gracefully in 1999. Their total revenues increased 10.6% the best top-line growth in four years, and profits surged 26%.
Many of last year's leaders are once again ahead of the pack. General Motors (No. 1) held tight to its position atop the revenue rankings. (2) But Wal-Mart Stores, fourth last year, rose to No. 2, aided by its $10.7 billion purchase of Britain's Asda Group (formerly No. 354). Meanwhile, General Electric (No. 9) can still claim the most profits on the planet--S10.7 billion, a 15% increase. Even GE, however, may need to start looking over its shoulder. In 1999,14 corporations earned more than $6 billion, up from seven a year before.
The rankings make clear that the gulf between denizens of the new economy and those of the old continues to widen. Companies in cutting-edge industries such as telecommunications, computer technology, and pharmaceuticals again trumped those in mature sectors such as steel, chemicals, and autos. "The rapid pace of technological change is forcing a continuous level investment in emerging sectors," says Bruce Steinberg, chief economist at Merrill Lynch. This creates a dilemma for older industries, Steinberg says, because "they don't have a lot of top--line growth potential." In a dramatic illustration of this gap, the two software companies on the list, Microsoft (No. 235), made a combined $8.2 billion last year. During the same period, the ten metal firms in the Global 500 lost a total of $245 million, one of the worst performances of any industry.
According to the passage, which of the following words is most suitable to describe the economic prospect of the Global 500 at the end of the 20th century？
A．Pessimistic.
B．Tense.
C．Sad.
D．Optimistic.
