b. Some verbs have a stative meaning and a different active meaning.
Typical examples are:
be, depend, feel, have, hear, measure, see, taste, think, weigh
Compare these uses:
Event
Jill's being noisy.
We're having an interesting conversation!
David's thinking about getting a new job.
I'm just tasting the soup.
I'm feeling terrible.
We're weighing the baby.
Bill, I'm depending on you to win this contract for us.
State
Jack is noisy.
Deirdre has a Porsche.
I think I like you!
This fish tastes awful!
I feel that you are wrong.
This bag weighs a ton!
It depends what you mean.
c. We can use the present continuous with some state verbs when we want to emphasise that a situation is temporary, for a period of time around the present. Compare:
The children love having Jean stay with us. (They love it when Jean stays) and
The children are loving having Jean stay with us. (Jean is staying with us now)
d. With some verbs used to describe a temporary state (e.g. ache, feel, hurt, look (= seem)), there is little difference in meaning when we use the present simple and present continuous:
What's the matter with Bill? He looks / is looking awful.
e. We can also use the present simple and present continuous like this in commentaries (for example, on sports events):
King serves to the left hand court and Adams makes a wonderful return. She's playing magnificent tennis in this match...
f. Making declarations: verbs describing opinions and feelings tend to be state verbs.
I hope you'll come to my party.
I bet you don't know the answer!
I hereby declare this hospital open!
Performative verbs.
a. We use performative verbs in the first person actually to perform an action, i.e. saying I apologise performs the action of apologising:
On behalf of the company, I apologise for any inconvenience caused
When these verbs 'perform' the function they express, they do not usually take the continuous.
Railtrack apologises for the disruption to services over the last three months. By saying this, the function of apologising is performed.
However, if we use the verb to describe the action rather than to do it, we can use the continuous.
The Railtrack chief executive was apologising profusely for the inconvenience.
