The tourist bus winded its way into a mountainous area. When it was【C1】______to make a turn, two passengers—a【C2】______of young lovers—were so attracted by the beautiful scenery that they【C3】______a stop to get down. They were left behind and the bus went【C4】______. Suddenly they heard a loud boom【C5】______of the road. It was a huge rock rolling down in the landslide that hit the bus and fell with it into a deep valley. The lovers were greatly【C6】______by the news that no passengers on board【C7】______When they calmed down they【C8】______and expressed their feelings in a few words. The above story was told by a guide when we were riding a tourist【C9】______to a scenic mountain. He asked us to guess what the lovers said【C10】______after the disaster that they had narrowly escaped. Often we read reports about traffic accidents,【C11】______which there were lucky ones who missed the bus and【C12】______the disaster. Those people usually said with a sigh of【C13】______. " Fortunately, I was not on board. " On our bus the passengers’【C14】______to the guide were various. But the answer was quite out of our expectation.

" The story passed from person to person as a sort of wit (智慧) test, but I think【C17】______It actually serves as a(n)【C18】______of a person’ s mind. I pay my heart-felt respect to the couple who, instead of feeling lucky,【C19】______themselves for causing the loss of lives. People all have heart for【C20】______, but it is often a flashing thought across one’ s mind that decides whether it is good or evil(邪恶的).【C6】
