Taiwan police cannot decide whether to treat it as an extremely act of stealing or an even cheat. Either way, it could be the perfect crime, because the criminals are birds—homing pigeons !

The crime begins with a telephone message to the owner of a stolen car: if you want the car back, pay up. Then, the car owner is directed to a park, told where to find a bird cage and how to attach money to the neck of the pigeon inside. Carrying the money in a tiny bag, the pigeon flies off.

There have been at least four such pigeon pick-ups in Changwa. What at first seemed like the work of a clever stay-at-home car thief, however,  may in fact be the work of an even lazier and more inventive criminal mind—one that avoids not only collecting money but also going out to steal the car in the first place. Police officer Chen says that the criminal probably has pulled a double trick: he gets money for things he cannot possibly return. Instead of stealing cars, he lets someone else do it and then waits for the car-owner to place an advertisement in the newspaper asking for help.

The thought is supported by the fact that, so far, none of the stolen cars have been returned. Also, the amount of money demanded-under 3,000 Taiwanese dollars–seems too little for a car worth many times more.

Demands for pigeon-delivered money stopped as soon as the press reported the story. And even if they start again, Chen holds little hope of catching the criminal. “We have more important things to do,” he said.

     Why play games? Because they are fun, and a lot more more besides. following the rules...planning

your next move ...acting as a team member...these are all "game" ideas that you will come across

throughout your life.

     Think about some of the games you played as a young child, such as rope-jumping and

hide-and-seek. Such games are entertaining and fun. But perhaps more importantly, they translate life

into exciting dramas that teach children some of the basic rules they will be expected to follow in the rest

of their lives, such as taking turns and cooperating(合作).

     Many children's games have a practical side. Children around the world play games that prepare them

for work they will do as grown-ups. For instance, sine Saudui Arabian children play a game called bones ,which sharpens the hand-eye coordination(协调)needed in hunting .

     Many sports encourage national or local pride. The most famous games of all, the Olympic Games,

bring athletes from around the word together to take part in friendly competitions, People who watch the

event wave flags, knowing that a gold medal is a win for an entire country, not just the athlete who earns

it. For countries experiencing natural disasters or war, an Olympic win can mean so much.

     Sports are also an event that unites people. Soccer is the most popular sport in the world. People on

all continents play it-some for fun and some for a living. Nicolette Iribarne, a Californian soccer player,

has discovered a way to spread hope through soccer. He created a foundation to provide poor children

with not only soccer balls but also a promising future.
