Comprehension and Precis:
Doctors and nurses were very busy during the civil exercise because there were many people volunteered as "casualties", which looked very realistic. The living helped to carry the dead and wounded to special stations. A six-year-old child, who pretended to be dead of shock, was carried by two adults. Some people were moved by the sight and they began to cry, when suddenly the child sat up. The doctor asked him to comment on his death and the child thought that they were all crazy.

Composition:
Early in the morning, people were informed on the radio that there would be a civil exercise and everyone was expected to participate in. However, the air-raid warning took everyone by surprise because they had never heard such a real and loud noise. People immediately stopped whatever they were doing and ran towards the nearest shelter. The streets were soon full of lines of people rushing to shelter and volunteers to casualties lying on the streets. Only one man was still doing his business at his own shop and objected to take part in the exercise. A policeman tried to argue with him that such kind of exercise was necessary preparation for inhabitants just in case. The man said that it was silly to pretend to ran down the streets and that the end of the world had come. The policeman was impatient to wait for him to practise the exercise and conducted him to the shelter. In a short time, the streets were only left with people pretending to be dead. The city was completely empty and quiet and only the wailing of the siren could be heard.
