1. I once ( knew) a village teacher who (was) partially blind. He (had been deprived) of one eye as the result of infection. His blind eye (had been taken) out, and a glass one ( inserted) in its socket instead. One day the teacher ( needed) to leave his class of small children alone for half an hour or so. But he (was held) back by one consideration. The children of the class (were) really unruly. He ( knew) that if they (were left) alone for any length of time they (would become) violent and complaints (would be make) by their parents.
Suddenly he (was striken) by an idea. In a moment his glass eye (was taken) out of its socket, and ( placed) on the table.
“Now, children”, he said, “I (am going) out for a few minutes but you (will be observed) all the time by my eye. If anything (is done) which (has not been approved) by me it (will be seen) by my eye, and the child (will be punished) when I (return).
The children (were impressed) very much, and the teacher (went) off.
But when he ( returned) an hour later it ( seemed) that a hurricane (had passed) through the classroom. The teacher (was astounded). “Evidently”, he thought,”I (have been outwited). I wonder how”.
In the classroom the tables (were overturned), the walls ( spattered) with ink from ink-bombs which (had been thrown) during the battle which still (was being fought) out as a manifestation of high spirits. In fact, a good time (had been had) by all.
The teacher ( wondered) why the presence of his glass eye (was not  respected). He ( looked) round for it and ( saw) that it (was covered) by a hat.
