In this exercise, students practise using adverbs of frequency in the right order. We recommend remembering these two rules:
Adverbs of frequency should be placed after the verb 'to be' e.g. She is never late.
Adverbs of frequency should be placed before other main verbs e.g. They rarely listen to classical music
Two sets of sentences can be selected. The first set contains only Present Simple sentences. The second set is more difficult as it contains sentences in Past Simple and Future Simple. If students do not know the meaning of given adverbs of frequency, we recommend doing exercise 514 first.
