10、People do not analyse every problem they meet. Sometimes they try to remember a solution from the last time they had a 1 problem. They often accept the opinion or ideas of other people. Other times they begin to act without 2 ;they try to find a solution by trial and error. 3 ,when all of these methods 4 ,the person with a problem has to start analysing. There are six 5 in analysing a problem.

　　6 the person must recognise that there is a problem. For example,Sam’s bicycle is broken, and he cannot ride it to class as he usually does. Sam must 7 that there is a problem with his bicycle.

　　Next the person must 8 the problem. Before Sam can repair his bicycle, he must know why it does not work. For example, he must 9 the parts that are wrong.

　　Now the person must look for 10 that will make the problem clearer and lead to 11solutions. For example, suppose Sam 12 that his bike does not work because there is something wrong with the brakes. 13 he can look in his bicycle repair book and read about brakes, 14 his friends at the bike shop, or look at his brakes carefully.

　　After 15 the problem, the person should have 16 suggestions for a possible solution. Take Sam as an example 17, his suggestions might be: tighten or loosen the brakes; buy new brakes and change the old ones.

　　In the end, one 18 seems to be the solution 19the problem. Sometimes the 20 idea comes quite 21 because the thinker suddenly sees something in a 22way. Sam ,for example, suddenly sees there is a piece of chewing gum（口香糖） stuck to a brake. He 23 hits on the solution to his problem: he must 24 the brake.

　　Finally the solution is25. Sam does it and finds his bicycle works perfectly. In short he has solved the problem.

9、Every year thousands of tourists visit Pompeii, Italy. They see the sights that Pompeii is famous for -its stadium（運(yùn)動場）and theatres , its shops and restaurants. The tourists do not , however, see Pompeii's people. They do not see them because Pompeii has no people. No one has lived in Pompeii for almost 2000 years.

　　Once ,Pompeii was a busy city of 22000 people. It lay at the foot of Mount Vesuvius, a grass-covered volcano（火山）.Mount Vesuvius had not erupted （噴發(fā)）for centuries ,so the people lf Pompeii felt safe.But they were not.

　　In August of AD 79,Mount Vesuvius erupted. The entire top of the mountain exploded, and a huge black cloud rose into the air. Soon stones and hot ash began to fall on Pompeii. When the eruption ended two days later, Pompeii was buried under 20 feet of stones and ashes. Almost all of its people were dead.

　　For cneturies, Pompeii lay buried under stone and ash. Then, in the year 1861,an Italian scientist named Ginseppe began to uncover Pompeii. Slowly, carefully, Ginseppe and his men dug. The city looked almost the same as it had looked in AD 79. There were streets and fountains, houses and shops. There was a stadium with 20000 seats. Perhaps the most important of all,there were everyday objects , whicn tell us a great deal about the people who lived in Pompeii. Many glasses and jars had some dark blue collue in the bottom, so we know that the people of Pompeii liked wine.They likde bread, too; metal bread pans were in veery bakery.In one bakery there were 81 round, flat loaves of bread- a type of bread that is still sold in Italy today. Tiny boxes filled with a dark , shiny powder tell us that women liked to wear eye-makeup.

　　Ginseppe has died , but his work comtinues. One-fourth has not been uncovered yet. Scientists are still digging, still making discoveries that draw the tourists to Pompeii.
