Explain that the students need to use the word provided, unchanged, within a phrase that completes the sentence in a way that it has the same meaning as the first sentence. The phrase they write must have between 3 and 6 words.
1) Think about the voice - can you switch between active and passive voice?
2) Look at the words directly before and after the gap. If a past participle follows the gap, you know you'll need the auxiliary verb 'have/had' in your response.
3) Do not use fewer than three or more than six words.
4) Do not modify the key word in any way.
5) Contractions count as two words.
6) Keep in mind comparative forms, phrasal verbs and colloquial phrases.
