Auxiliary verbs
PEG 106-7
Auxiliaries here are used both alone and as part of various tenses of ordinary verbs.
Read the following (a) in the negative (b) in the interrogative. These sentences, except for nos. I and 13, could also be used for question tag exercises (see Exercise 13).
Note:
1 may for possibility rarely begins a sentence. Instead we use do you think (that) + present/future or is + subject + likely + infinitive:
Tom may know.
