The mechanism for facilitating the purchase and sale of goods，services，commodities， and securities abroad is known as the foreign exchange market．The actual purchase and sale of foreign exchange generally is accomplished through the international departments of large commercial banks．

The demand for foreign exchange can be either transaction or speculative based. The transactions demand for foreign exchange comes from those who wish to make payment to a foreign country for the purchase of a good，a service，or a security purchased from a resident of，or a company located in a foreign country．A resident of the United States wishing to make a remittance to a relative in the United Kingdom would also affect the demand for sterling. The same would be true if the resident of one country wished to make a contribution to a charity located in another country．Speculative demand for a currency is generated by the confidence speculators have in that currency vis-à-vis other world currencies．This demand could be based on political and/ or economic factors，as demonstrated during the 1970s．For example，when the mark was strong and the sterling weak，speculators would sell sterling to buy marks．

The supply of foreign exchange is provided by those who are willing to sell a currency they hold．This may include those who will receive payments in a foreign currency for the export of goods and services，the sale of securities to foreign residents，or the receipt of foreign exchange resulting from gifts or contributions made by foreign countries．International speculators arc also sources of supply when they feel the currency they hold is weak relative to other world currencies．

Aphrodite loved Adonis more than she did to heaven, for he was

a brisk, lovely young hunter. She abandoned her residence

at Olympus and took to the woods, where she dressed

herself up like a huntress and kept the youth companion all day 【M1】 __

long. With him she roved through bushy grounds and groves and

over hills and dales, cheering hounds and pursuing game of a

harmless sort. They had a great time together. So, she 【M2】 __

warned him many times to chase wild beasts like lions and 【M3】 __

wolves, but the young man just laughed at the idea.

One day, after warning him thus, she left to Olympus in 【M4】 __

her chariot. Quite by chance Adonis' hounds found a boar, that 【M5】 __

roused Adonis to enthusiasm. He hit the beast with a dart, and 【M6】 __

the boar, turning on him ,buried its white tusk deep into his

tender side and trampled him to death.

When Aphrodite came back to find her lover cold in death,

she burst into a passion of tears: Unable to wrest him back from

the low world, she sprinkled nectar on Adonis' blood and 【M7】 __

turned it into anemone, a delicate purple flower.

Aphrodite was, therefore, still inconsolable. In grief and 【M8】 __

despair she flew to Zeus and implored him to restore Adonis to

her. Though she had Zeus' sympathy, Hades was by no means

prepared to comply with her request. After the much dispute a 【M9】 __

compromise was worked out under which Adonis was to spend

half the year above ground with Aphrodite, but the rest six 【M10】 __

months in the Elysian Fields. Therefore, in spring time Adonis

came back to the loving embrace of Aphrodite, but when winter

came he had to return most reluctantly to Hades.
