The article was for an art students' magazine. You will see that it hangs together in a way that the oral version did not. This is done partly through the use of connecting words, known as cohesive devices. You might think I should prefer painting with oils to painting with acrylics. The reason that I like using acrylics rather than oils is that they dry faster.
Oils can take weeks, even months, to dry.
I prefer acrylics because I tend to paint at speed since I like the spontaneity associated with this process. By contrast, artists who paint with oils need a long period of time to work and rework their paintings and while this has its advantages, I am too impatient for that. The activity that follows invites you to reflect on some general characteristics of written English. For example, because is followed by a reason and for example is followed by an example. It is clear to anyone what the words this and that refer to every time they appear.
