In the past, people lived a poor life in old houses.
The rubbish was everywhere. As a result, there was
serious pollution. People went out mostly on foot or
by bicycle. Few visitors came here.
Now there have been great changes here. People
enjoy blue skies, green mountains and clean water.
There are modern communities with tall buildings
everywhere. Almost each family has a car. Mobile
phones and computers are quite popular. Thousands of
visitors come to visit here every year.
I think, with the development of science and
technology, people will enjoy a more comfortable and
healthier life in the future.
