A topic sentence: how to do it

Start your paragraph with a sentence that says its main idea: what you want the reader to understand. Not 'This paragraph is about cycling' but 'Cycling to work is the easiest way to stay fit.' Then every other sentence must explain, prove or give an example of that idea. If a sentence is about something else, cut it. After your main idea, ask yourself 'why?' and 'for example?' and write the answers.

Example of a topic sentence

Reading before bed helps many people sleep better. To begin with, a book gives the mind something calm to focus on, so the worries of the day slowly fade. For example, a tired parent who reads a few pages often feels relaxed enough to fall asleep easily. In addition, reading a paper book instead of using a phone avoids bright light, which can keep the brain awake.
