Most earthquakes occur within the upper 15 miles of the earth's surface, but earthquakes can and do occur at all depths to about 460 miles. Their number decreases as the depth increases. At about 460 miles one earthquake occurs only every few years. Near the surface earthquakes may run as high as 100 in a month, but the yearly average does not vary much. The extent of the disaster in an earthquake depends on many factors. If you carefully build a toy house with an erect set , it will still stand no matter how much you shake the table. But if you build a toy house with a pack of cards, a slight shake of the table will make it fall. An earthquake in Agadir was not strong, but it completely destroyed the city. Many stronger earthquakes have done comparatively little damage. If a building is well constructed and built on solid ground, it will resist an earthquake. Most deaths in earthquakes have been due to faulty building construction or poor building sites. A third and very serious factor is panic. When people rush out into narrow streets, more deaths will result. There is one type of earthquake disaster that little can be done about. This is the disaster caused by seismic sea waves, or tsunamis . These are often called tidal waves, but the name is incorrect. They had nothing to do with tides. In certain areas, earthquakes take place beneath the sea. These submarine earthquakes sometimes give rise to seismic sea waves. The waves are not noticeable out at sea because of their long wave length. But when they roll into harbors, they pile up into walls of water 6 to 60 feet high. The Japanese call them "tsunamis" meaning "harbor waves", because they reach a sizable height only in harbors. Tsunamis travel fairly slowly, at speeds up to 500 miles an hour. An earthquake warning system is in use to warn all shores likely to be reached by the waves. But this only enables people to leave the threatened shores for higher ground: There is no way to stop the oncoming wave. According to the passage, the number of factors that may determine the extent of the disaster in an earthquake is _ . A) two B) five C) four D) three

Nails in the Fence There once was a little boy who had a bad temper . His father gave him a bag of nails and told him that every time he lost his temper, he must hammer a nail into the back of the fence. The first day he had driven 37 nails into the fence. Over the next few weeks, as he learned to control his anger, the number of nails hammered daily gradually _ . He discovered it was easier to hold his temper than to drive those nails into fence. Finally the day came when the boy didn't lose his temper at all. He told his father about it and the father suggested that now pull out one nail for each day that he was able to hold his temper. The days passed and the young boy was finally able to tell his father that all the nails were gone. The father took his son by the hand and led him to the fence. He said," You have done well, my son, but look at the holes in the fence. The fence will never be the same. When you say thing in anger, they have a scar just like these holes. You can put a knife in a man and draw it out. It won't matter how many times you say 'I am sorry ', the wound is still there. A verbal wound is as bad as physical one." The little boy then understood how powerful his words were. He looked at his father and said " I hope you can forgive me ,father, for the holes I put in you." "of course I can," said the father. When you say something with anger, they will leave a scar just as you put a nail in and then draw it out. It means _ . A) you shouldn't put a nail in the fence B) if you put a nail into the fence, you shouldn't draw it out C) it will leave a scar when you draw a nail out D) you will hurt somebody when you lose your temper.
