The map illustrates the different layouts of a school in 1985 and now.
In 1985, a car park was constructed in the north end of the school as well as a field was in the south area and they were connected by a road built in the central part. In the east side of this road, there was a two-story classroom block; in the west side, an office, a library and another car park were located.
At present, the school has changed a lot. The most noticeable is that trees are planted in the middle area and surrounded by two more classrooms, with the library replaced by a resource center and a computer room. Moreover, a part of field is cleared to make way for a pool and a fitness center. The car park north of the school remains but its size is smaller, surrounded by a wider road.
Overall, it can be seen that more facilities have been constructed in the school and the population has risen from 1500 to 2300.

In contemporary society, most families are capable to afford home appliances such as television, microwave, oven and so on. It is generally accepted that those technological goods have brought great convenience to our life although they do generate negative effects on environment.
In terms of merits of using domestic appliances, the most obvious is that people’s quality of life has been boosted. Take TV as an example; watching TV is a preferable means of relaxation for people to spend their leisure time and release stress, with amusing programs, entertainment news as well as soap operas shown on the screen. Another case is that the application of microwave, oven and rock cookers in the kitchen saves housewives from heavy housework and even assists them in cooking delicious meals efficiently. Furthermore, consumers’ demands for electric appliances stimulate the development of manufacturing industries, which creates more job opportunities and bring the government increasing tax revenue.
However, it must be admitted that the worldwide use of household appliances inevitably contributes to environmental degradation. To commence with, in an attempt to maintain these devices function, a great amount of electricity has to be consumed, which is largely generated from fossil fuels such as coal and petroleum. In the long run, the scarcity of natural resources will become a tough issue for human beings. In addition, harmful gas emission is another big concern. As a matter of fact, in the use of fridge and air conditions, Freon (a kind of chemical gas) is emitted into air, leading to the destruction of ozone layer.
In conclusion, as far as I am concerned, it is a positive development that people can purchase various electric appliances. However, environment-friendly technology should be adopted in its production to protect environment.
