B

How long can a person live without breathing ? Provably for only four to six minutes. The air we breathe in supplies the oxygen that is necessary for keeping every part of the body alive. And the brain, which itself controls breathing, is the first to suffer if oxygen is lacking . If no air enters the lungs, the heart will continue to beat for a little longer, supplying the blood to the brain and other parts of the body., But soon, the supply of oxygen already in the blood is used up. First, the patient loses consciousness, because the brain is no longer getting enough oxygen, the brain can survive undamaged for only about four minutes, The heart may survive for as long as 12 minutes, But within six minutes the person will almost certainly be dead.

Being not far from the sea, London is famous for its fogs(雾). The worst of them happened on December 4, 1952. All movement in the Town came to a stop. It was almost impossible to drive or ride in anything. The streets which led into the

centre were filled with buses that moved two miles an hour. Soon, however, the traffic was stopped. Being left by their drivers, the buses and cars stood empty in the streets, Many who usually traveled by bus took underground(地铁). But there were so many people there that the gates had to be closed. Being caught in the fog, people felt their way along the walls of houses with one hand, while they put out the other in front of them so as not to knock against something or somebody.

　 　At the Opera House (歌剧院) they got through the first act(幕)of La Traviata before so much fog had spread(蔓延)into the building that the singers could not see the conductor.
