Physical: The gardener feeds the ducks.
Mental: She likes the migrating birds best.

Burt is the gardener's assistant.
He seems afraid of the swans.
One swan looks angry.
In fact, the swans are hungry.

1. A verb that expresses a state of being often functions as a linking verb. A linking verb links, or connects, the subject with a noun or adjective in the predicate that names or describes the subject.
Peanut is a toad. (Toad tells more about what Peanut is)
Peanut is tiny. (Tiny describes Peanut)
2. Some Verbs can function as either linking verbs or action verbs.
Linking: The lily pond smells stagnant.
The gardener felt tired.
Action: The squirrel smells its food.
She felt the tree's thick leaves.
3. To help you decide whether one of these verbs is a linking verb, try substituting are or is for the verb. If the sentence still makes sense, the verb is probably a linking verb.
The pigeons look comical. The pigeons are comical. The pigeons=comical

Poison ivy has been growing in the woods.
Richard was collecting firewood in that area.
Now his hands and arms are itching.
Because verb phrases like these express action in progress, they are called progressive forms. The progressive is not a separate tense. It is actually an additional form for each of the six tenses. The progressive forms tell about continuing action in the present, the past, or the future.
The progressive forms are made up of a form of be and the present participle. The helping verb shows the tense.
Present progressive: We are studying plants in school now.
Past progressive: We were studying plants when the bell rang.
Future progressive: We will be studying plants again tomorrow.
Present perfect progressive: We have been studying plants for several days.
Past perfect progressive: We had been studying plants for only a day when we had our field trip.
Future perfect progressive: We will have been studying plants for weeks by the time our project is done.
Tell the progressive form of each verb phrase.
