    Breathe, wave and smile. Along with more than 300 other seniors, I marched into the stadium on the afternoon of May 10. The audience burst into deafening cheers. The huge stadium shook with all the whistling and clapping.

    It was as if a Hollywood superstar had walked on stage. And indeed, every single senior that day was a star of the moment. Each deserved it. The seniors had been preparing for four years for this once-in-a-lifetime moment—the commencement (graduation ceremony).

    Seated, I waited anxiously for the opening address. As a foreign exchange student, I was not able to receive a diploma. However, I still had the wonderful feeling of being part of things. Like the other graduates, I was dressed in marron cap and gown.

    Our principal, Mr. Glover, delivered a short, warm greeting. The US national anthem followed and then, hands on chests, a solemn Pledge of Allegiance(美国的爱国誓言).

    Students who had excelled academically gave farewell speeches. The tears in some eyes convinced me that many had deep feelings about the occasion. It was as the class motto says, “Life brings us tears, smiles and memories. The tears dry; the smiles fade; but the memories last forever.”

    Then came the core (the most important part) of the commencement. Hundreds of names were announced. Each graduate walked across the stage to receive his or her diploma from the principal. From the different cheers each graduate got, we had the funny sense that it was a kind of competition of who could cheer the loudest.

    To be honest, the presentation of diplomas got boring. A girl sitting next to me even started yawning. But it wasn't boring for those receiving the diploma: they would treasure the moment the principal placed the sacred brown document in their hands for the rest of their lives.

    A new page in the book of that person's life had turned. They were glimpsing their futures: futures of challenge, hardship, perhaps loneliness too, which would take all of their courage.

    Are some people born clever, and others born stupid? Or is intelligence developed by our environment and our experiences? Strangely enough, the answer to both these questions is yes. To some extent our intelligence is given to us at birth, and no amount of special education can make a genius out of a child born with low intelligence. On the other hand, a child who lives in a boring environment will develop his intelligence less than one who lives in rich and varied surroundings. Thus the limits of a person's intelligence are fixed at birth, but whether or not he reaches those limits will depend on his environment. This view, now held by most experts, can be supported in a number of ways.

    It is easy to show that intelligence is to some extent something we are born with. The closer the blood relationship between two people, the closer they are likely to be in intelligence. Thus if we take two unrelated people at random (随机地) from the population, it is likely that their degrees of intelligence will be completely different. I f on the other hand we take two identical (完全相同的) twins they will very likely be as intelligent as each other. Relations like brothers and sisters, parents and children, usually have similar intelligence, and this clearly suggests that intelligence depends on birth.

    Imagine now that we take two identical twins and put them in different environments. We might send one, for example, to a university and the other to a factory where the work is boring. We would soon find differences in intelligence developing, and this indicates that environment as well as birth plays a part. This conclusion is also suggested by the fact that people who live in close contact with each other, but who are not related at all, are likely to have similar degrees of intelligence.

The history of Australian Rules Football

    Australian Rules Football is called by many nicknames. Lovers of the game just call it "football" or "footy." When contrasted with other forms of football, it is called "Aussie Rules" or "AFL". AFL stands for Australian Football League, which is the most prestigious league in Australia.

    Australia Rules Football was created by Tom Wills in 1858. He wanted to create a sport that would keep cricket players fit through the winter. He began by writing a letter that explained his purpose to a sports magazine. It also called for the creation of a football club. In 1858, Wills and others played an experimental match that was the first game of Australian football. But few details about this match have survived.

    On August 7, 1858, two important events for the game occurred. The Melbourne Football Club was founded. It was one of the world's first football clubs in any code. Also, a famous match between Melbourne Grammar School and Scotch College was played. It was umpired(仲裁)by Tom Wills. A second day of play took place on August 21, and then there was a third and final day on September4. The two schools have competed every year since.

    The game is played between two teams of 18 players on an oval that can also be used for cricket. These playing fields can be up to 185m long. This is almost four times the size of fields used in other forms of football.

    A point called "a behind" is scored when the ball goes across the line and between a goal post and a behind post. A behind point is also scored if the ball is touched by any body part of either team's member as it passes between the goal posts. A goal is worth six points, and a behind is worth one point.
