12.1
The population of this town (was) about 20,000 five years ago. Every
year it (is increasing) more than 1,000 a year. By the end of next decade
it (will have doubled).
12.2 They have just (come) back. I think, it (has taken) them a half an hour, not more. Now they (are speaking) to my mother.
12.3 Tornadoes (speed) through the island every year. By the end of
this season they (will have damaged) many buildings and (injured) many
people.
12.4 Her husband (has been watching) football on TV since breakfast. But it
seems, the match (is not going) successfully, you (should not ask) anything
about the game.
12.5 The concert (was) almost over, and the singers (were) tired, but
the spectators were still ( waiting) for new songs. You see, it (will be repeated)
again tomorrow.
