Finding the topic sentence and examples
Paragraphs which explain something usually have a
topic sentence, which tell us what the paragraph is
mostly about. The topic sentences is often the first
sentence in the paragraph. A paragraph also has
details that help explain the topic. One type of detail is
an example. In order to understand what a paragraph
is about, you need to be able to see the difference
between the topic and details (i.e., the examples).
