Answer 1

Once upon a time there were  three Billy Goats Gruff. One day they decided to visit their favorite hill. "I expect you to find something good to eat there," said the elder goat. Before they could get to the hill they had to cross a bridge. They knew that a mean ugly troll lived under the bridge but they had never seen him before. They also (knew)13 that the troll (liked to fight)15. "If we (meet)16 the troll, I (will fight)17 with him," said the younger goat. 

While the three goats (approached)18 the river the troll (was sitting)19 in the water (having)20 a wonderful time. Soon he (heard)21 the goats (come или coming)22 onto the bridge. "Where are you going?" asked the troll. "Who are you 24?" The first goat who (was crossing)25 the river was the younger brother and he (became)26 afraid. He (did not want)27 the troll (to eat)28 him. So he (said)29 that he (was)30 small and thin. He (promised)31 the troll that the latter soon (would see)32 his bigger brothers who  were)33 more dilicious. So the troll (let)34 the small goat (to cross)35 the bridge. The troll (was asked)36 to let the middle brother (to cross)37 the bridge and he (was allowed)38 that as he (thought)39 that the elder goat (was)40 the fattest. "I (have been living)41 under the bridge for many years but I have never had)42 such a delicious meal," said the troll. But the elder goat was big and fat and strong. He (had fought)43 and (won)44 many battles. When he (was asked)45 (not to move)46 he (came)47 closer to the troll and (gave)48 him a big push. "I (won't know)49 if I have never seen)50 you again, Troll, but if I (do)51, (be)52 careful or I (will kill)53 you." The troll (fell)54 into the river and nobody had never (seen)55 him again
