Listen to the story again,and fill in tblanks.
Jasper White believes in ancient myths. Car owners always park their cars outside his gate, so he has put up “No Parking” signs but they have not paid any attention to them. Now he has put an ugly stone head over his gate. It is the head of Medusa, the Gorgon. He wants her to turn car owners to stone but she has not done so yet.
Translate these sentences: He has just bought a new house in the city. Ever since he moved in, he has had trouble with motorists. He always finds that someone has parked a car outside his gate. Jasper has put up' No Parking' signs outside his gate, but these have not had any effect. It is one of the ugliest faces I have ever seen. But none of them has been turned to stone yet!
