Introduction Some writing is good in sentence structure but either poor in coherence or in cohesion. The problem of coherence is that the sequence of information is not always clear and the problem of cohesion is that the sequence of information is acceptable, while the connection between it is not so good. The question is how to analyze and improve these different weakness in writing. We have two methods. One to focus on coherence, the other to focus on cohesion. In this essay, the method used is based on the principle that coherence and cohesion should work together. I use this approach as a tool to edit and display the analysis of coherence and cohesion in the passage entitled ’ Father & Son". This passage is presented as a guided writing exercise in College English Course, Intensive Reading, Band 3, p271.
