A ‘gap text’ is a text in which some words or sentences have been left out. You have to fill in the missing words or sentences.
To tackle a gap text you …
– don’t read the possible answers yet
– read the text before and after the gap
– determine whether there is a connection between the text before and after the gap
– determine the function of the missing word or sentence
– think of a word or sentence that you believe is fitting and see whether it is one of the possible answers to fill the gap
