17．Last Saturday afternoon，I took a walk with some of my friends in the central park．The park was full （93）of freshness and greenness of spring，with the sun shining and birds（94）ssinging．When we were enjoying the fantastic scenery around us，something unpleasant （95）ccaught my eye．A young couple in a boat were eating things，talking and laughing loudly as （96）though/if they were the only people in the world．What's （97）wworse，they threw paper bags and banana skins into the lake，totally （98）ignoring （忽视）the sign"No Littering"nearby．What a shame!
Such behavior left me （99）ddeep in thought．If all visitors to the park do as the couple did，the lake will be severely （100）polluted （污染）and soon turned into a huge dustbin．I think all of us should mind our behavior in （101）public （公共）places and do what we can to protect the environment．（102）Onlyin this way can we live in more comfortable and beautiful surroundings．

The flying carpet travelled so fast that next minute they were in Zimbabwe．Daisy turned around and found that she was being watched （71）by an elephant．"Have you come to take my photo？"it asked．In r （72）elief Daisy burst into laughter．"Don't laugh，"the elephant r （73）eplied immediately，"We used to be an endangered species．Farmers hunted us without m （74）ercy．They said we destroyed their farms，and money from tourists only went to the large tour companies．So the government decided to help．They allowed tourists to hunt only a c （75）ertain number of animals if they paid the farmers．Now the farmers are happy and our numbers are increasing．So good things are being done here to save local wildlife．"

At 3：42 a．m．everything began to shake．It seemed a （76）s if the world was at an e （77）nd!Eleven kilometers directly below the city the greatest earthquake of the 20th century had begun．It was felt in Beijing，which is more than two hundred kilometers away．One-third of the nation felt it．A huge crack that was eight kilometers long and thirty meters wide cut across houses，roads and canals．Steam burst from holes in the ground．Hard hills of rock became rivers of dirt； In fifteen terrible seconds a large city lay i （78）n r （79）uins．The suffering of the people was extreme．Two-thirds of them died or were i （80）njured during the earthquake．Thousands of families were killed and many children were left without parents．The number of people who were killed or seriously
injured reached more than 400，000．
