Unit 6 Seasons
Verbs can be transitive or intransitive. Transitive verbs (vt.) need an object. They don’t make sense without one. But intransitive verbs (vi.) don’t need an object to make sense. Many verbs can be used both ways.
David loves the summer. (love, vt. )
The girls are swimming. (swim, vi. )
The boys are playing football. (play, vt. )
The boys are playing in the park. (play, vi. )
The basic parts of a sentence are the subject (S), the verb (V) and the object (O). There are two basic sentence structures.
S+V+O → Millie flies a kite.
S+V → The temperature drops.
S V O
S V
A linking verb (linking v. ) links a subject to an adjective/noun or an adjective/noun phrase that describes it. This word or phrase is called the predicative(P) and the sentence structure is subject(S)+linking verb (V)+predicative(P).
