This useful exercise gives examples and then lessons on how to use the word 'but' when expressing divided ideas.
(For example: I like tea BUT I don't like coffee!)
It also gives the students a chance to come up with the ideas themselves in the second exercise, including hints to help them along.)
This is a simple Word document and can easily be edited to suit your own students.
As with all my worksheets, they are neatly laid out with plenty of 'white space', and contain no unnecessary images and borders.
Also, the English is plain and simple, the names are very commonly used names and the situations are real world!
