Commas can be used to contrast opposites in a sentence written in phrase form, as in "The tutor was very friendly, not mean and scary the way Peta expected." Commas are also used to separate elements in a list and parts of a sentence introducing direct speech, such as "This is my favourite story, Peta told her tutor." However, commas should not be overused as it makes the writing difficult to read, similar to overusing full stops. The document provides examples of correct comma usage and a warning against overusing commas.
2. Contrasts A comma can show where there are opposites in a sentence, especially when written in phrase form. The tutor was very friendly, not mean and scary the way Peta expected. The students wanted to write a research paper, but the tutor had asked for a short story.
3. Speech A comma is used at the end of sentences when people are speaking as there will be a full stop later on. This is my favourite story, Peta told her tutor. We cant eat till lunchtime, his mother said, but we set the table.
4. Warning! Be careful, not to, overuse, commas, because, it is so, hard to read, just like. Full stops. Revise this PowerPoint and the one from last week to prepare for the punctuation test.
