People speak for different purposes, for example to describe something or to tell a story. Depending on the rhetorical purpose, the speech is presented quite differently. Stories are different from lectures.
You can choose passages with different purposes. These are:
These describe something.
These tell a story.
These give information about something, or explain something.
These are formal lectures on an academic topic.
These are talks in which the speaker presents a point of view.
These either describe a place or situation so the listeners could imagine it, or it describes a process so that the listener could do it.
These describe a series of related events; a story.
These provide information about something or explain something. The information is presented as a matter of fact, rather than opinion.
At the lower difficulty levels, this just relate facts, often personal facts, but at the higher level these include reasons, explanations, definitions, classifications, analysis, and cause and effect relationships.
A short lecture on an academic topic, that is presented in a formal authoritative manner. These are shorter than actual university lectures, but are otherwise similar in style and content.
These are talks on a specific topic; some are talks given to a group of people such as in a seminar or a business meeting, while others are arguments for a set of ideas or opinions with conclusions based on reasons, examples, and evidence.
