If you are asked to describe a scene, an object or a person, you could deal with the topic in the following way.
1. Description of a Scene
Introduction
It is a general impression of the scene, i.e., a busy town centre, a stormy seashore, a deserted village.
Body of the composition
This may consist of the description of buildings, traffic, people and their actions, animals, trees, flowers, etc. Included in this part are colors, shapes, sounds and smells. Make your description vivid by using figures of speech, as the river disappearing like a serpent.
Conclusion
Normally, it consists of the impression the scene has made on you. The scene may make you happy, puzzled, indifferent, lonely or sad. Describe any association or memories that the scene has brought about in you.
2. Description of an Object
The description of an object usually consists of:
(a) the class to which the object belongs, e.g., a thermometer is a scientific instrument for measuring temperature;
(b) the general look of the object, i.e., its shape, size, color, material, etc;
(c) particular features which enable the object to be identified.
