The statement is false. The three types of sentence patterns are subject-verb, subject-verb-object, and subject-verb-complement.
Step-by-step explanation:
The statement is false. The three types of sentence patterns are subject-verb, subject-verb-object, and subject-verb-complement. The terms 'air,' 'graze,' and 'mixed' do not represent sentence patterns, but rather they describe different types of verb spottings in the Halliday's Systemic Functional Grammar. The term 'air' spotting refers to a verb without any nominal groups, the term 'graze' spotting refers to a verb with a nominal group but without a complement, and the term 'mixed' spotting refers to a verb with a nominal group and a complement.
