1.Changes In My Hometown
My home town is a beautiful place. It stands beside a wide river and is rich in fish and rice.
But in the old days it was a poor and backward little town. Many people had no work. They lived a hard life.
In 1949 my hometown was liberated. Since then great changes have taken place there. The streets have been widened. Factories, schools, hospitals, cinemas and theatres have sprung up one after another. The life of the people is greatly improved.
I love my hometown. All the more I love its people. They are working hard so as to make it still richer and more beautiful.
2.POPULATION PROBLEMS
The population problem may be the greatest challenge of the present time. In other words, People are being born faster than they are dying, or they are dying at a slower rate than they are being born. The average life span has doubled in the last 50 years. That people live much longer results in the serious population problem.
People around the world are becoming more concerned about the population explosion. It is hoped that there can be some control over the number of people that are born, but population control is a subject which touches the moral & religious beliefs of many people.

Even if many families have fewer children, there will still be problems of food, water & power supply.

Here Students’ Union calls on everyone to give away your old clothes and pocket money and bring your used books, mp3s or something else to sell in the bring-and-buy sale.
