It was a cold, wet day on June 6, 2010, when 14-year-old Wasana arrived at school. Waiting outside his classroom for his classmates to 36 , Wasana stared at the 37 . Then his eyes fell upon the 18-metre-high hill that 38 at the back of the classroom.
He 39 large amounts of rainwater flowing down the hill, and water was also bubbling(冒泡) at the base of a rock on the hill. For a few minutes, Wasana 40 the water, wondering why it looked so 41 . Then it hit him — the 42 was similar to the video he was shown during Disaster Management classes. Fearing a 43 disaster, he shouted 44 at the students waiting outside their classrooms. “Run, run, don’t stay here! The 45 on the hill is going to fall on us!”
Chaos(混乱) broke out as the 46 ran to the open area that had been appointed as an emergency gathering point. When some teachers 47 Wasana, he showed them the water gushing from the hill, and they started leading the students to safer ground.
Just then Principal Gurusinghe drove into the school. Wasana ran over to tell him what was happening. After 48 the site, Gurusinghe knew the school was in 49 . The enormous rock at the top of the hill could come crashing down 50 .
51 a group of teachers and older students, Gurusinghe climbed the hill and tried to make the water flow away from the rock. They were too 52 : ten minutes later, they heard screams as the huge rock rushed down the hill. There was little Gurusinghe and his group could do as they watched the earth 53 their classrooms. Thanks to Wasana’s 54 action and careful observation, 55 was hurt in the incident.

A car that runs on coffee is unveiled(shown to the public for the first time)today but at between 25 and 50 times the cost of running a car on petrol, the invention won’t please any motor industry accountants.
Nicknamed the Car-puccino, it has been created using a 1988 Volkswagen Scirocco bought for £400 and it was chosen because it looked like the time-traveling DeLorean in the movie Back To The Future.The car will be driven the 210 miles between Manchester and London powered only by roasted coffee granules (颗粒).It has been built by a team from the BBC1 science programme Bang Goes The Theory and will go on display at the Big Bang science fair in Manchester to show how fuels other than traditional petrol can power vehicles.
The team calculates the Car-puccino will do three miles per kilo of ground coffee (咖啡粉) — about 56 cups of espressos (浓咖啡) per mile.The journey will use about 70 kilos of ground coffee which, at supermarket prices of between £13 and £26 a kilo depending on brand and quality, will cost between £910 and £1,820, or between 25 and 50 times the £36 cost of petrol for the journey.In total, the trip will cost 11,760 espressos, and the team will have to take ‘coffee breaks’ roughly every 30 to 45 miles to pour in more granules.They will also have to stop about every 60 miles to clean out the ‘coffee filters’ to rid them of the soot and tar which is also generated by the process.So despite a top speed of 60mph, the many stops mean the going will be slow, with the journey taking around ten hours.
Sadly, the inventors will still have to pay duty on their coffee fuel---even though tax collectors at Her Majesty’s Revenue and Custom haven’t yet worked out how much.
Nick Watson, producer of Bang Goes The Theory, said, “Coffee, like wood or coal, has some carbon content so you can use it as a fuel.The coffee needs to be very dry and in granules to allow the air to move through the pile of coffee as it burns.The brand doesn’t matter.” He said the same technology could be used to power a car on other unusual fuels, such as woodchips or nut shells, construction or agricultural waste.
