assignment:Is the way something seems to be not always the same as it actually is ?

Most people tend to consider what they see as facts or truth. As far as I am concerned, what we see is sometimes conceiving and misleading. Things are not the same as what they appear to be. The truth sometimes hides beneath the surface.
Before the advent of telescope, which enabled Galileo Galilei to prove that the earth resolves around the sun, people believed that the sun went around the earth ,which was the centre of the universe because they believed in what they saw. To them, the sun rose and set every day while the earth remained still. It appeared that the sun went around the earth. However, what they saw was not the truth. The movement of the sun as well as the earth was not the way it seemed to be. It was because people lived on the earth and couldn¡¯t feel the movement of it that they perceived the universe in a wrong way.
My personal experience also demonstrated my view. Before I studied chemistry, I always regarded clean water as the purest thing in the world and didn¡¯t contain other materials because it was transparent and we couldn¡¯t see anything in it. But when I learned chemistry and carried out various experiments, I realized that water was not as pure as it appeared. Though we couldn¡¯t see other chemicals with our eyes in it , it didn¡¯t mean that there didn¡¯t exist other chemicals. Through the experiments, I knew that there were numerous particles which were invisible to naked eyes in the seemingly pure water. Water, as a matter of fact, is not pure at all.
The examples above indicate that there are things different from the way they seem to be. What we see is not always the true. We should try our best to explore the truth that lies beneath the appearance in order not to be deceived by our eyes.
