for example, 'for another example, for the third example.... or just one 'for example'?
during composition, I give three examples. the first, I begin with ' for example' to introduce my example. then I want to give the second example. In this situation, I should write the second example directly following the first one, or I need to write ' for another example' to remind the readers another example is coming? (I doubt its correctness because I have never met it)
