第三篇
The World Cup
This summer's World Cup competition will see teams competing to play the world's best
football.But the football they play will not all be of the same kind.The fans expect different
styles of play from Brazil,Germany, or Italy.
What makes Brazilian football Brazilian?Our style of playing football contrasts with the
Europeans because of a combination of qualities of surprise,accuracy and good judgment.
This style has won Brazil five world cups.Yet many Brazilian fans only count four of these
victories.In 1994,the team abandoned this style for modern,scientific training and tactics.
The team won the cup,but in a boring way.
The Italians think differently."To many Italians,the score 0-0 has a glorious quality,
suggesting perfection,"says the British football writer Simon Kuper.In the Italian culture,
the idea of face is very important.This is why Italian teams are traditionally built around
strong defences.The Dutch footballer Johan Cruyff once said that Italian teams never
exactly beat you.It's just that you often lose to them.
In Holland,there is a tradition of decision making through argument and discussion.It is
a society where everybody is expected to have a point of view."Every Dutch player wants
to control the game,"says Arnold Muhren."You play football with your brains and not your
feet."
"A Dutch player argues,"says Simon Kuper."An English player obeys his superior.
He is a soldier."The qualities valued in English football are military-strength,aggression
and courage.This can make for exciting football.But it also means that the English find it
difficult to use skillful players.David Beckham is usually criticized for his failure to defend一
despite the fact that he is an attacker.
If the English like to fight,the Germans like to win.In recent years,Germany has tried
to change its image as a country of ruthless efficiency and a desire for victory at all costs.
But Germans are quite happy for these qualities to remain in their national football team.
"Football is a simple game,"Gary Lineker once said."You kick a ball about for ninety
minutes and in the end the Germans win."
It's difficult to predict who will win this year's World Cup.There is no strong favorite.But
a look at the track record of previous winners shows that it is the nations with the strongest
national characteristics in the football that perform best.It seems that you need to know
where you come from if you want to get to the top.
What is one expected to do in Holland?
A.To play football.
B.To express his or her opinion freely.
C.To make a fuss about nothing.
D.To beat his or her opponents ruthlessly.

Passage Two
Analysts have had their go at humor,
and I have read some of this interpretative literature, but without being
greatly instructed. Humor can be dissected, as a frog can, but the thing dies in
the process and the innards (内在部分) are discouraging to any but the pure
scientific mind. In a newsreel theatre the other day I saw a
picture of a man who had developed the soap bubble to a higher point than it had
ever before reached. He had become the ace soap bubble blower of America, had
perfected the business of blowing bubbles, refined it, doubled it, squared it,
and had even worked himself up into a convenient lather. The effect was not
pretty. Some of the bubbles were too big to be beautiful, and the blower was
always jumping into them or out of them, or playing some sort of unattractive
trick with them. It was, if anything, a rather A. they give vent to their sorrows in a laughable way B. they have much trouble in their life and they are melancholy C. they are more sensible of the sadness of life and they endure and express the pain cheerfully D. they are mostly clowns with a breaking heart
