"must be" and "were" = linking verbs -- neither transitive or intransitive
I thought linking verbs were intransitive
Thanks Ms. Sue
From U of Ottawa's website:
Many linking verbs (with the significant exception of "be") can also be used as transitive or intransitive verbs. In the following pairs of sentences, the first sentence uses the highlighted verb as a linking verb and the second uses the same verb as either a transitive or an intransitive verb:
Griffin insists that the water in Winnipeg tastes terrible.
In this sentence, the adjective "terrible" is a subject complement that describes a quality of the water.
I tasted the soup before adding more salt.
Here the noun phrase "the soup" identifies what "I tasted." "The soup" is the direct object of the verb "tasted."
My neighbour's singing voice sounds very squeaky despite several hours of daily practice.
In this example, the phrase "very squeaky" is a subject complement that describes or identities the nature of the "singing voice."
Upon the approach of the enemy troops, the gate-keeper sounded his horn.
Here the verb "sounded" takes a direct object, the noun phrase "his horn."
Cynthia feels queasy whenever she listens to banjo music.
In this sentence, the adjective "queasy" is a subject complement that describes Cynthia.
The customer carefully feels the fabric of the coat.
Here the noun phrase "the fabric of the coat" is the direct object of the verb "feels" and identifies what the customer feels.
