Passage Four

John Paul Jones was one of the founders of the United States Navy. During the Revolution, the colonies were desperate. They needed men to lead their small ships against the British fleet. Jones was more than willing to fight.

John Paul Jones had once been a captain of a British merchant ship. In 1773, his crew mutinied. One member of the crew tried to gain control of the ship. Jones shot the man to death. The mutiny took place near the port of Tobago, an island in the Caribbean. Authorities there decided to have a trial. This meant certain death for John Paul Jones, since the whole crew would testify against him. One night during a thunderstorm, he escaped from the jail.

He fled to the United States and lived with a family named Jones. His real name was John Paul. He added the name of Jones to his, in honor of the family. He outwitted the British ships that were sent to hunt him down.

When the American Revolution ended he went to serve in the Russian navy. There, he fought the Turks and achieved one of the few major naval victories in the history of Russia. He died in Paris at the age of forty-five.

John Paul Jones is considered both an American and Russian hero, but the English considered him a fugitive.

48. John Paul Jones won a major victory for the Russian navy against the ______.

A. French

B. British

The Major Currencies in the World

The currencies of the world's major economies have names and backgrounds that are as diverse as the countries themselves.

The dollar is the name for the currency used in many countries including the United States , Canada, and Australia. It gets its name from a silver coin minted during the Middle Ages in a small valley, or "Thal" , in Bohemia called Joachimathal. Just a sausage Frankfurt called "Joachimsthaler" or simply " Thaler" , and came to be called " dollar" in English.

The pound, used in Britain, Egypt, and Lebanon among others, refers to the weight used in determining the value of coins, based on precious metals such as gold or sterling. The penny has the same origin as the word pawn,found in terms such as pawn shop , and originally meant "to pledge". A penny , like any currency , is a " pledge " of value.

In Italy and Turkey , the currency is called lira. The word is based on the Latin lira, meaning "pound" and once again referring to the weight of the original coins.

In Spanish , the word meaning " weight" , peso is used to describe the coins that were based on a certain weight of gold or silver. Originally,there were gold coins called peso de oro and silver ones called peso de plata. In Spain , the currency is called peseta, meaning "small peso". The word peso is used to describe the currency in many Spanish-speaking countries in Latin America.

In Denmark, Norway, and Sweden, the word for crown-krone in Denmark and Norway,krona in Sweden-is used to describe the currency that was originally minted by the king and queen,with royal crowns stamped on the earlier coins. Today,the crown has been replaced by other symbols , but the name remams.

The franc,used in France, Switzerland, and other countries and territories,is based on the early coins used in France, that bore the Latin inscription franconium rex , meaning "king of the Franks". The com, as well as the country, took its name from one of the original tribes that settled in the area, the Franks.

The German mark and Finnish markka derive their name from the small marks that were cut into coins to indicate their precious metal content. The German mark, deutsche mark in German ,is often called by its shortened name , D-mark.

The ancient Chinese word yuan meant "round", or "round thing". The name of the Japanese currency, the yen, and the name of the Chinese currency, the yuan , both derived from the old Chinese word,refer to the round shape of the original coins.

Problem may arise when using the plural forms of these currencies. Most take the English plural "s", for example , pounds , dollars , francs , Deutschmarks , etc. However , some are invariable: yuan, yen, baht, and rand. Others keep the plural form of the language spoken in the country of origin: lira-lire , krone-kroner, krona-kronor , markka-markkaa , etc.

Currencies are said to be convertible or invertible. Semi-convertible currencies can only be bought or sold through a country's central bank for documented commercial transactions. The exchange rates are fixed. Semi-convertible currencies are typical of third world countries.

A hard currency is one which is strong and unlikely to fall in value. A soft currency is one from a country with a week balance of payments and for which there is little demand.

Questions for reading :

tant way of reading a large, big-city newspaper is to put it into different sections. Can you find these separate sections: world news, national and local news, sports, business, entertainment, opinions, ads？ Does your paper have other sections？ News stories give facts, not the reporter's opinions. Some newspaper editorials (社论) come out with the writer's name, but many newspapers only carry editorials without putting the writers' names on. You can be a better reader if you know what to expect in a newspaper. For example, you can expect headlines to leave out unnecessary words. You can expect to find the most important facts in the leading paragraph (the first paragraph) of a news story. You can expect important news items to be on the front page. You can expect less important items to be on the inside pages. Most of all, the more you know about news of the present time, the more you will understand what is in the newspaper; important stories are generally presented one day and followed up on following days. So, an important way to read newspapers is reading one frequently. A good way to read a newspaper is to find separate sections and read according to your needs.A.T
