Many people believe that our climate has changed very markedly.

I have been collecting the pictures with bridges since I graduated from the University. Now I have collected enough to organize an interesting exhibition.

She has been reading a fairy tale to the children since breakfast. They haven't finished yet.

Those people have been waiting for a tram for the last fifteen minutes. I'm afraid, they don't know that the electricity has gone out.

What has happened to Mary? John has been ringing her up the whole evening and nobody has answered.

"You have come out at last," he said. "Well, I have been standing here long, and have been listening to the nightingale."

So, you have arrived. We just were speaking of you.

"How long have you known about it?" - "I have known it all the time."

"Why did you turn off the music?" - "I have been playing the records for hours; I'm tired now."

I definitely have decided to give Pendle up.
