Evaluation of energy-saving methods
Chrysler Building
Location: New York, New York
Building Type: commercial office tower
Construction System: steel frame, metal cladding
This report describes energy-saving measures taken by the building manager of the Chrysler Building. These measures range from the simple and quick to the expensive and time consuming.
The most significant energy saving measures were achieved by planting a variety of plants with different growth characteristics, both on the roof and on individual office balconies, which added cooling shade in the summer. The use of inexpensive exterior bamboo blinds during summer months produced significant reductions in need for air-conditioning, which saved the Chrysler building a considerable amount of money. Surprisingly, installing double-paned windows was the least cost-effective measure, despite recommendations by environmental organizations.
Future contributions to the Chrysler Building energy-saving initiative will include planting deciduous trees. In the summer, these will provide shade; in the winter, the leafless branches will allow sunlight into the building's interior.
Note: Building design accounted for 30% of energy emissions and the construction materials of the Chrysler Building accounted for another 30%.
What is the main topic of the report？
A．Gardening flowers and plants
B．Choosing and installing windows
C．Redesigning office space
D．Reducing energy costs
听力原文： Not until somewhat recently(that is, in terms of human history) did people find a need for knowing the time of day. As best we know, 5,000 to 6,000 years ago great civilizations in the Middle East and North Africa initiated clock-making. With their bureaucracies and formal religions, these cultures found a need to organize their time mom efficiently.
The Egyptians were the next to formally divide their day into parts something like our hours. Obelisks(slender, tapering, four-sided monuments) were built as early as 3500 B.C. Their moving shadows formed a kind of sundial, enabling citizens to partition the day into two parts by indicating noon. They also showed the year's longest and shortest days when the shadow at noon was the shortest or longest of the year. Later, markers added around the base of the monument would indicate further time subdivisions.
Another Egyptian shadow clock or sundial, possibly the first portable timepiece, came into use around 1500 B.C. to measure the passage of "hours". This device divided a sunlit day into 10 parts plus two "twilight hours" in the morning and evening. When the long stem with 5 variably spaced marks was oriented east and west in the morning, an elevated crossbar on the east end east a moving shadow over the marks. At noon, the device was turned in the opposite direction to measure the afternoon "hours".
In the quest for more year-round accuracy, sundials evolved from flat horizontal or vertical plates to more elaborate forms. One version was the hemispherical dial, a bowl-shaped depression cut into a block of stone, carrying a central vertical gnomon(pointer) and scribed with sets of hour lines for different seasons. The hemicycle, said to have been invented about 300 B.C., removed the useless haft of the hemisphere to give an appearance of a half-bowl cut into the edge of a squared block.

根据下面内容，回答题：
Gold used in jewelry is mixed with harder metals to add strength and durability. The metals added can also be used to change gold" s color， giving it a fashionable rose or white tint， or to lighten or darken the natural yellow， tone of pure gold.Mixtures like these， of less costly metals with more valuable ones， are called alloys. Copper and silver are the most common metals mixed with gold to make yellow gold jewelry. White gold is usually made with an alloy of gold and nickel.
The measure of gold" s purity is called a karat. The higher the karat rating，the higher the amount of pure gold: 24 karat is pure gold，18 karat is 75% pure gold，14 karat is 58.5% pure gold， and 9 karat is 37.5% pure gold. All other things being equal ，the higher the percentage of pure gold used in the alloy，the more valuable and expensive the jewelry wll be.
Gold jewelry pieces are usually stamped with a marking to identify the karat amount. While gold that is 24K is too soft for jewelry，18K，14K and 9K gold are all appropriate for jewelry， and they all make pieces that look great and wear beautifully.
Which of the following statements best.captures the main idea of this passage？ 查看材料
A.Although gold is very valuable，it is also very expensive.
B.Gold jewelry is stamped with its karat ，weight.
C.Gold jewelry is made using alloys.
D.Colored gold is more valuable than white gold.
As is known to all, the organization and management of wages and salaries are very complicated. Generally speaking, the Account Department is responsible for calculations of pay, while the Personnel Department is interested in discussions with the employees about pay.
If a firm wants to adopt a new wage and salary structure, it is essential that the firm should decide on a method of job evaluation and ways of measuring the performance of its employees. In order to be successful, 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 those requirements is given a value, generally in "points", which are added 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 ability to solve problems. Because of the difficulty in measuring management work, however, job grades for managers are often decided without reference to an evaluation system based on points.
In attempting to design a pay system, the Personnel Department should compare the value of each job with those in the job market. It should also consider economic factors such as the cost of living and the labor supply.
It is necessary that payment for a job should vary with any distinctions in the way that job is performed. Where it is simple to measure the work done, as in the work done with the hands, monetary encouragement schemes are often chosen, for indirect workers, where measurement is difficult, methods of additional payments are employed.
If a company wants its new pay structure to be successful, it is necessary to______.
A．give the workers extra pay to encourage them
B．share the same opinion between the Trade Union and the employers
C．consult some problems associated with pay
D．adopt a special way to evaluate the performance of its employees
But while momentum is building for several measures, including a bill that would allow the Organization of the Petroleum Exporting Countries to be sued in American courts under antitrust laws, there is little sign that any of the proposals would do much, if anything, to lower prices quickly. And the oil executives warned that government intervention might only make things worse. Instead, they called on Congress to allow more drilling and exploration for domestic oil.
The increasing urgency to seem aggressive about gasoline prices was apparent on Tuesday when the House voted by an overwhelming 324 to 84 to approve the bill, commonly referred to as NOPEC, which classifies OPEC as a monopoly in violation of the Sherman Antitrust Act. Senate Democrats have included that measure as part of a package of legislation intended to address the high price of gasoline, along with the tax on windfall profits and a measure to tamp down speculation in the oil futures market that many lawmakers think is contributing to the run-up in prices.
At the Judiciary Committee hearing, Democratic senators struggled to have the executives explain how oil prices had risen so high. The senators expressed doubt that basic laws of supply and demand were at work and suggested instead a more sinister combination of monopolistic behavior. by oil-producing countries, speculation in the futures markets and sheer corporate greed.
On Monday, President Bush signed a bill temporarily suspending the purchase of crude oil for the nation's Strategic Petroleum Reserve. Mr. Bush had initially opposed such action but relented after the House and Senate approved the bill by wide margins. Senator Richard J. Durbin, Democrat of Illinois and a strong supporter of Senator Baraek Obama's presidential bid, made a particularly pointed attack, in which he seemed to warn the oil executives that they would soon no longer have such a good friend in the White House. He also suggested that Mr. Bush should be doing more to press the oil companies to help lower prices at the pump, while acknowledging that it would be difficult to pass a windfall profits tax while Mr. Bush was still in office.
Senate Democrats were angry with the oilmen because______.
A．they get tax-free pay packages
B．Congress took on actions but in vain
C．the showdowns were merely a routine
D．oil prices had risen so high
