Reading and writing

Pay attention the making stages in a discussion.

So far in these units we have practiced parts of the language that are useful for particular purposes. In Units we shall practice putting together a number of language functions in order to express our ideas. In developing an argument or discussion we need to express our opinion or views, and then we need to conclude. We shall look at introductions and conclusions.

When we discuss or argue in academic writing, we normally need to present a balanced view. We must also ensure that facts and opinions are clearly separated. We often look at what other people have already said on the same subject or we look at other ideas.

When reading, we probably look at the advantages and disadvantages of a particular idea or proposal or action; we look at arguments for (or in favour) and against. Then we try to evaluate the different opinions, comparing and contrasting, and eventually give our own opinions.
