Soccer is played by millions of people all over the world, but there have only been a few players who were really great. How did these players get that way, was it through training and practice, or were great players “born, not made”?

Firstly, these players came from places that have had famous stars in the past—the players that a young boy can look up to and try to imitate. In the history of soccer, only six countries have ever won the World Cup, three from South America and three from Western Europe. There has never been a great national team, or a really great player, from North America or from Asia. Secondly, all these players have had years of practice in this game. Alfredo Di Stefano was the son of a soccer player, as was Pele. Most players begin playing the game at the age of three or four.

Finally, many great players came from the same kind of neighborhood(地方), a poor, crowded area where a boy’s dream is not to become a doctor, lawyer, or businessman, but to become a rich, famous athlete or entertainer(演员). For example, Liverpool, which produced the Beatles, had one of the best English soccer teams in recent years. Pele practiced in the street with a “ball” made of rags(破布). And George Best learned the tricks that made him famous by bouncing(使球跳) the ball off a wall in the slums(贫民窟) of Belfast.

All great players have a lot in common, but that doesn’t explain why they are great. Hundreds of boys played in those Brazilian streets, but only one became Pele. The greatest players are born with unique(独一无二的) quality that sets them apart from all the others.

1. According to the passage, which of the following statements is true?

A. Millions of people all over the world are playing soccer, but only six countries have ever had famous stars.

B. Only six countries have ever had great national teams.

C. Soccer is popular all over the world, but truly great players are rare.

D. Soccer seems least popular in North America or Asia.

2. The underlined word “imitate” is closest in meaning to          .

A. copy              B. respect           C. admire              D. adore

3. Liverpool and Brazilian streets are two geographic terms used to illustrate(例证)         .

A. where soccer players get their way

B. why they can have great soccer teams

C. what a poor, crowded area can provide a future soccer player with

D. how the environment in a poor, crowded area affects a soccer player’s success

4. To become a great soccer player, a series of factors(因素) are directly mentioned, expect          .

A. age and birth                             B. personality(个性) and character

C. training and practice                        D. family and neighborhood

  Today we will talk about expressions with “apple”.“Apple pie order” means very well organized.Nobody is sure when and where this expression began.It is said that the women of New England loved to have everything in its place, especially when they were making apple pie.

  Another expression “apple of discord” describes the opposite condition.The ancient story says that all the gods and goddesses were celebrating a marriage when Discord, one of the gods, threw a golden apple on the table which was to be given as a prize to the most beautiful goddess.How could they choose among Juno, Minerva and Venus? When Paris decided to give the golden apple to Venus, Juno and Minerva were very angry and threatened(威胁)him.This began the long Trojan War.

  Calling a tomato “a love apple” was a mistake.In the sixteenth century, Spain imported the tomato from South America to Morocco, and then Italian businessmen took it to Italy.The Italian name for the tomato was pomo di Moro-apple of the Moors(荒野).When French growers imported it from Italy, they thought di Moro meant d’amour, the French word for love.And so pomo di Moro became the apple of love.

  People believe many things about the apple.One belief is that it has great powers of keeping people healthy.“An apple a day keeps the doctor away.” Another belief is based on fact.“One rotten apple spoils the barrel.” The expression has come to mean that one bad person in a group can cause everyone to act badly.
