Of all the subjects taught in school, I Geography best. It is the only subject which teaches me everything I need to know about the world we live in, for example, vegetation, way of life of people, climate, agriculture and economy.
I learn about the countries around Malaysia and in other parts of the world and, since I cannot visit and see for myself every country in the world, I get at least a good picture of these countries by studying Geography. I am very interested in finding out more about other countries especially those that experience snow when winter comes. I often wonder about the life of the people in these countries. What would it be to be dressed in thick clothes and boots and living in snow-covered houses amidst fir trees? Then, there are the hot desert lands that stretch for miles and miles without a tree in sight. They, too, fascinate me. I marvel at the inhabitants who are able to tolerate the intense heat of the burning sun, traveling along miles of barren, hot land on camels where the only vegetation found would be the few palm trees growing at an oasis. The wide range of food which we enjoy daily such as butter, cheese, fruits, bread that comes from wheat and many others lead me on to find out how they are processed and imported into Malaysia and finally make their appearance in our homes.
As I study more in Geography, I understand better the changes in weather conditions, for example, why there are hot and dry seasons or cool rainy days during the monsoon season and how deserts are caused.

I learn many subjects in school. But the one I enjoy learning is History.
History tells us how people lived ages ago. It also tells us how men had to struggle to make the world a better place to live. Many pupils, however, do not to read History. They say that there are too many names and dates to remember. But they do not understand that if we do not know about the past, we can not understand the present properly. In fact, only a study of History will make us realize that everything we do today is the result of what our grandfathers and others before them did in the past. So, History is the long story, we learn many interesting things.
I love history so much that i have a lot of history books in my house. Some day, i might even write a history book myself.
