1).A: I hear you've just had a trip by air. What was it like?
B: At least 6 hours and I should have arrived tired and dirty. From
now on I'd rather fly every time 1 have to travel on business.
A: I'm surprised to hear that. I thought you would be thrilled by it.
B: The best thing about it was that it took me only two hours to get to
the place. And I felt quite fresh and ready for work.
A: How long would it have taken you by train?
B: Oh, quite good. It could have been more exciting though.
2). Mary: You ought to have let me know you were going to be so late.
Cliff: Yes, of course. That must have been the trouble. At the station.
I had to line up for the ticket because my season-ticket had run
out and I had no change for the slot machine.
Mary: Why was that? Whatever could have happened?
Cliff: I didn't know that myself. When I got on the bus, it crawled
along at 10 miles an hour and I was afraid I'd miss my train.
Mary: It must have been the rush hour.
Cliff: It must have been cancelled due to some dispute on the
railway. So I had to wait for the next train.
Mary: You should have bought a return ticket in the morning.
Cliff: Of course I could have. And then I found the train I'd meant to
catch wasn't running.
Mary: You ought to have got a taxi.
