If you have time, you . . . . . . . . the nature museum.

The director of the school is either deaf or fool, if . . . . . . . .

. . . . . . takes charge of a prison.

At this time on next Sunday, you . . . . . travelling by plane to the moon.

Listen, an announcement . . . . . to cancel all the flights due to heavy ice-fall.

You speak so . . . . . that I can’t understand properly.

. . . . . . goods were carried on the truck.

Last year, when I last met her, she told me she . . . . . . . . a letter every day for the last two months.
