Paragraph Structure

For to make a paragraph must take into account three aspects, these are; the main idea, supporting sentences and concluding sentences.
The main idea is the principal topic, from there arrise all ideas, and almost always says the topic. Is like trunk of a tree, because the supporting sentences are the branches; these have to than to be united to the main idea, just than with more details.
Finally the concluding sentences they are like the fruit of the tree; are the consecuenses of the paragraph, but always have to than to be related with the topic.
So if you want to make a good paragraph, you have to imagine a tree, this is the paragraph structure.
