Excerpt number one is a expository text. Expository texts are used to explain or describe certain things or events. In this first excerpt, the writer is explaining and giving details about fossils and what they are and how they are formed. In expository texts, readers can often find definitions and explanations about specific themes.
The second excerpt is a persuasive text. Persuasive texts are usually texts whose main goal is to persuade you: the reader; in other words, these texts make you believe or think in a particular way. In this particular excerpt, the writer uses phrases like “Join with them and help preserve the beauty of the world” or “Enjoy a new creative program that allows you to experience a working vacation in the Grampians National Park of Australia” (in these examples, the writer uses specific words to make you believe that you will have some benefits if you do what they say).
The last excerpt is a narrative. Narrative texts are usually stories that are characterized for having connected events, real or imaginary, presented in a sequence of words, like in this specific excerpt. In this excerpt, the writer is connecting events so that the reader can feel that he or she is part of a particular situation within the story. In this particular excerpt, the writer is neither explaining nor persuading the reader, but telling or sharing a story to them.
