- aExcuse me. Have you got any books on genetic engineering? I've looked for them everywhere,but I can't find any.
- bI'm not sure if we've got any now. Books of that kind are on this shelf. Well, I'm afraid we've sold out.
- aWhat a pity! I should have come earlier.
- bCome some time next week if you like. I think we'll have got some by then.
- aOk, I will.
