Supporting Details 1
Now that we know how to state the topic or theme of a paragraph, let us learn how to describe, define, or explain the theme of a paragraph by using supporting details.

Generally, the main idea is supported by details which may draw comparisons, contrast ideas, quote statistical data, draw graphs or give vivid description.

What are supporting details?
Supporting details constitute the body of the paragraph, support the topic sentence and develop and establish the main idea. They give details of the topic sentence and make the topic sentence convincing and connect ideas within a paragraph. These details answer the question raised by the main idea like who, what, when, why, or how.
Thus, a paragraph is organized with a main idea, substantiated by supporting details and summarized by a concluding sentence.
The Human Body

The human body is a wonderful piece of work that nature has created.

It is not beautiful like the body of a butterfly or peacock but it is shaped practically. It can do many types of work which other animals cannot.
It is not strong like the body of a tiger. But in place of physical strength it has a big and sharp brain. By using this brain the human physique has been able to overcome many of its limitations. By sitting in an aeroplane it flies faster than a kite, by riding a motorcycle it travels faster than a leopard, and by firing a machine gun it fights much better than a tiger.
In spite of all this, the human body suffers from many diseases because it has a weakness for habits such as smoking, drinking and overeating. When it is healthy the body can give great pleasure but when it is sick it can cause great pain.
The wise man would always keep his body fit because a healthy mind can work only in a healthy body.
