At A1 in the category of MODALITY, there are two points:
- affirmative question form.
- ‘can’ to make a request.
and in the category of QUESTIONS:
a limited range of modal verbs + subject + main verb to form ‘yes/no’
*Because these points clash with higher levels, the main difference to note is that all the examples from the English Grammar Profile for these points have the pronouns can + ‘you’ or ‘we’.
