People do not analyse every problem they meet. Sometimes they try to remember a solution from the last time they had a__26problem. They often accept the opinion or ideas of other people. Other times they begin to act without__27 ; they try to find a solution by trial and error. __28_, when all of these methods__29 , the person with a problem has to start analysing. There are six__30 in analysing a problem.

__31 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__32 that there is a problem with his bicycle.

Next the person must__33 the problem. Before Sam can repair his bicycle, he must know why it does not work. For example, he must__34 the parts that are wrong.Now the person must look for__35 that will make the problem clearer and lead to__36 solutions.For example, suppose Sam__37 that his bike does not work because there is something wrong with the brakes. __38 , he can look in his bicycle repair book and read about brakes, __39 his friends at the bike shop, or look at his brakes carefully.

After__40 the problem, the person should have__41__suggestions for a possible solution. Take Sam as an example__42 ,his suggestions might be:tighten or loosen the brakes; buy new brakes and change the old ones.

In the end, one__43 seems to be the solution__44 the problem. Sometimes the__45 idea comes quite__46 _because the thinker suddenly sees something new or sees something in a__47 way. Sam, for example, suddenly sees there is a piece of chewing gum(口香糖)stuck to a brake. He__48 hits on the solution to his problem:he must__49 the brake.

Finally the solution is__50 . Sam does it and finds his bicycle works perfectly.In short he has solved the problem.

When I was in medical college, I went camping with some of my friends. The season was summer; therefore, we chose to go to the seaside. After arriving there, we rent a room and left our luggage there. We finished lunch and then decided to rent a boat because the sea and the weather were beautiful.
We started to row, but about one mile out, the weather suddenly changed. Although the weather was not good, we didn't want to give up, but finally my friends and I agreed that we should go back. We tried to change the boat's direction, but as soon as we changed it, the oarlock (桨架)broke. Therefore, we were unable to turn back. We had to wait for help because we couldn't do anything.
After seeing the change of weather, we shouldn't have continued to row, but it was too late. We regretted(后悔) it. The sea changed a lot, the waves got very high, and the boat began to shake like a cradle(摇篮). One of my friends started to cry; another started to vomit(呕吐). Three hours passed, and nobody came to help us. We were just praying.
Fortunately, after five long hours of waiting, two big boats came to rescue us and we escaped. If they hadn't come to get us, we would have crossed the border between Turkey and Greece because the border was very close.
This story is the most exciting story of my life because we could have died, but luck was with us and we escaped.

Many of the most damaging types of weather begin quickly, strike suddenly, and disappear rapidly, destroying small areas while leaving neighboring areas untouched．Such event as a tornado struck the northeastern part of Edmonton, Alberta, in July 1987．Total damages from the tornado went beyond $250 million, the highest ever for any Canadian storm．
Traditional computer models of the atmosphere have limited value in predicting short-lived local storms like the Edmonton tornado, because the available weather data are generally not detailed enough to allow computers to study carefully the slight atmospheric changes that come before these storms．In most nations, for example, weather-balloon observations are taken just once every twelve hours at places separated by hundreds of miles．With such limited data, traditional forecasting models do a much better job predicting general weather conditions over large areas than they do forecasting specific local events．
Until recently, the observation intensive method needed for exact, very short-range forecasts, or “Nowcasts,” was not possible．The cost of equipping and operating many thousands of conventional weather stations was extremely high, and the difficulties concerned in rapidly collecting and processing the weather data from such a network were hard to overcome．
Fortunately, scientific and technological advances have overcome most of these problems．Radar systems and satellites are all able to make detailed, nearly continuous observation over large areas at a lower cost．Communications satellites can send out data around the world cheaply and immediately, and modern computers can quickly collect and analyze this large amount of weather information．
Meteorologists（气象学者）and computer scientists now work together to design computer programs and video equipment able to change weather data into words and graphic displays that forecasters can understand easily and quickly．As meteorologists have begun using these new technologies in weather forecasting offices, Nowcasting is becoming a reality．
1．Why can’t traditional computer models predict short-lived local storms?
A．The weather data people collect are often wrong．
B．Detailed weather data in some small areas are not available．
C．The computers are not advanced enough to predict them．D．The computers are not used to forecast specific local events．
2．The word “Nowcast” in Paragraph 3 means ________．
A．a network to collect storm data?
B．a way of collecting weather data
C．a more advanced system of weather observation
D．a forecast which can predict weather in the small area
3．What can make “Nowcasts” a reality according to the passage?
A．Scientific and technological advances． B．Advanced computer programs．
C．Computer scientists．?              D．Meteorologists．
4．What does the passage mainly talk about?
A．The advantages of “Nowcasts”．        B．A tornado in Edmonton, Alberta．
C．The difficulty in predicting tornado． D．A great development in weather forecast．

Sydney—A shark savaged a schoolboy's leg while he was surfing with his father at a beach in Sydney on February 23.It was the third shark attack along the coast of Australia's largest city in a month.
The 15-year-old boy and his father were in the water off Avalon，on Sydney's northern beaches，around dawn when he was attacked.The city's beaches are packed with locals and tourists during the summer months.
“The father heard a scream and turned to see his son thrashing(激烈扭动)about in the water，”the police said.“Fortunately，the shark swam away and the boy was helped to the shore by his father.”
Lifesaving Club spokesman Nick Miller said，“It got him around the top of his left leg and the father came and dragged him out of water.”He said the boy was bleeding heavily when he was brought to the shore.“There was a lot of pain，as you can imagine.”The teenager was airlifted to hospital for treatment for leg injuries.
Police said the bites “cut through to the bone”，but the boy did not appear to have sustained any fractures (骨折)．He was in a stable condition now.
Several beaches were closed after the attack.Water police and lifeguards were searching for the shark，while the police hoped to identify its species by the shape of the bite marks.But they said it was too early to say what type of shark attacked the boy.“I don't even know if he saw it，”Miller said.
Many shark species live in the waters off Sydney's beaches，but attacks on humans are still relatively rare.However，there were two attacks on successive days earlier this month，one on a navy diver in Sydney harbor，not far from the famous Opera House，and the other on a surfer at the city's world-famous Bondi beach.
Fishermen say shark numbers are on the rise.There is a ban on commercial fishing in the harbor，which has increased fish stocks.Marine experts also claim environmental protection has created a cleaner environment，attracting sharks closer to the shore as they chase fish.Many shark species，including the Great White—the man-eaters made famous in Steven Spielberg's Jaws—are protected in Australian waters.
【小题1】The report mainly tells us ________.

A．shark attacks on humans are on the rise

B．sharks attacked humans three times in one month

C．a boy was attacked by a shark at a Sydney beach

D．shark numbers are increasing in the waters off Sydney's beaches

【小题2】The underlined word “savaged” in the first paragraph probably means “________”．

【小题3】What do we know about the city of Sydney from the passage?
B．Sydney harbor is not far from the famous Opera House.
C．There are many locals and tourists on its coast all the year round.
D．There are few shark species in the waters off Sydney's beaches.
【小题4】About the injury of the boy we know that ________.

A．he was losing much blood when he was dragged out

B．he was very nervous when he was sent to hospital

C．he may be in danger of losing his leg

D．he was injured in the right leg

【小题5】All the following are the causes of Australia's sharks' increasing EXCEPT that ________.

A．environmental protection has created a cleaner environment

B．a ban on commercial fishing has increased fish numbers

C．many shark species are protected in Australian waters

D．the film Jaws has made the Great White famous
