To learn to think is to learn to question. Those who don't question never truly think for themselves. These are simple rules that have governed the advancement of science and human thought since the beginning of time. Advancements are made when thinkers question theories(理论) and introduce new ones. Unfortunately, it is often the great and respected thinkers who end up slowing the progress of human thought. Aristotle was a brilliant philosopher whose theories explained much of the natural world, often incorrectly. He was so respected by the scientific community that even 1,200 years after his death, scientists were still trying to build upon his mistakes rather than correct them!

Brilliant minds can intimidate up­and­coming thinkers who are not confident of their abilities. They often believe they are not as good as the minds of giants such as Aristotle, leading many to accept current ideas instead of questioning them.

I, like many thinkers of the past, once believed in my mental weakness. I was certain that my parents, my teachers—adults in general—were always right. They were like a textbook to me; I didn't question what was written on those pages. I respected them, and accepted whatever they told me. But that attitude soon changed. My mind's independence was first developed in the classroom.

A stern, 65­year­old elementary­school science teacher once told me that light is a type of wave. I confidently went through years of school believing that light is a wave. One day，however, I heard the German exchange student mention that light could be made up of particles(粒子). As the others laughed at his statement, I started to question my beliefs.

Maybe the teachers and textbooks hadn't given me the whole story. I went to the library, did some research and learned of the light­as­a­wave versus light­as­a­particle debate. I read about Einstein's discovery of the dual nature of light and learned the facts of a paradox(悖论) that puzzles the world's greatest thinkers to this day. Light behaves as both a particle and a wave, it is both at once. I realized I had gone through life accepting only half of the story as the whole truth.

Each new year brought more new facts, and I formulated even more questions. I found myself in the library after school, trying to find my own answers to gain a more complete understanding of what I thought I already knew. I discovered that my parents and teachers are good tools in my quest for knowledge, but they are never the final word. Even textbooks can be challenged. I learned to question my sources, I learned to be a thinker. I once believed that everything I learned at home and at school was certain, but I have now discovered to re­examine when necessary.

Questions are said to be the path to knowledge and truth, and I plan to continue questioning. How many things do we know for sure today that we will question in the future? At this moment, I know that our sun will burn for another five billion years, and I know nothing can escape the gravity of a black hole. This knowledge, however, may change in the next 20 years—maybe even in the next two. The one thing we can control now is our openness to discovery. Questions are the tools of open minds, and open minds are the key to intellectual advancement.

“Did you hear what happened to Adam Last Friday?” Lindsey whispers to Tori.

With her eyes shining, Tori brags, “You bet I did. Sean told me two days ago.”

Who are Lindsey and Tori talking about? It just happened to be yours truly, Adam Freedman. I can tell you that what they are saying is (a) not nice and (b) not even true. Still, Lindsey and Tori aren’t very different from most students here at Linton High School, including me. Many of our conversations are gossip(闲话). I have noticed three effects of gossip: it can hurt people, it can give gossipers a strange kind of satisfaction, and it can cause social pressures in a group.

An important negative effect of gossip is that it can hurt the person being talked about. Usually, gossip spreads information about a topic–breakups, trouble at home, even dropping out-that a person would rather keep secret. The more embarrassing or shameful the secret is, the juicier the gossip it makes. Probably the worst type of gossip is the absolute lie. People often think of gossipers as harmless, but cruel lies can cause pain.

If we know that gossip can be harmful, then why do so many of us do it? The answer lies in another effect of gossip: the satisfaction it gives us. Sharing the latest rumor can make a person feel important because he or she knows something that others don’t. Similarly, hearing the latest rumor can make a person feel like part of the “in group.” In other words, gossip is satisfying because it gives people a sense of   belonging or even superiority(优越感).

Gossip also can have a third effect: it strengthens unwritten, unspoken rules about how people should act. Professor David Wilson explains that gossip is important in policing behaviors in a group. Translated into high school terms, this means that if everybody you hang around with is laughing at what John wore or what Jane said, then you can bet that wearing or saying something similar will get you the same kind of negative attention. The do’s and don’ts conveyed through gossip will never show up in any student handbook.

The effects of gossip vary depending on the situation. The next time you feel the urge to spread the latest news, think about why you want to gossip and what effects your “juicy story” might have.

My family and I belonged to a country club located across the street from the Long Island Sound. Each summer, the big attraction for us was the pool. I learned how to swim and joined the swimming team but was never really a good swimmer. However, swimming in my younger days was a way to keep cool, and swimming on a team gave me identity and a sense of belonging. It also became invaluable many years later.

Fast-forward (快进) to 1973 — I was married, pregnant and had a home. What made our little home even more wonderful was when I discovered that four blocks away was Rath Park Pool! For the next 30 years, most of our summer days were spent around that pool.

Each of my five kids took swimming lessons and learned all the different swimming strokes     (姿势). They later joined the swim team and competed in meets. My daughter even became a lifeguard at the town pool. I sat back and happily took it all in!

As much as I would have liked to have life stand still, it doesn’t. My children outgrew their pool days and moved on. But the pool was still four blocks from my home, so I began to take up swimming again. And it was far better than I ever could have imagined. I got so much out of it that I joined the local pool so I could swim year-round. Whenever I swam, I would always come out feeling physically and mentally refreshed. I often felt that if I looked hard enough, I would be able to see all of the worries and problems I’ve had in life, sitting at the bottom of the pool!

What has swimming taught me? I’ve learned that balance is the key to being a good swimmer. If you are balanced in the water, you have no resistance. Working on staying balanced made me realize the similarities between life in and out of the swim lane (泳道). If you work on keeping yourself balanced, you will be able to swim right through the stress and problems life throws at you!
