Before leaving, he bought a Rolex watch with the 19 made through years of work after school and the scholarships. At the airport he had to accept the 20 customs check. The watch on his wrist was also demanded to be taken down for 21 . Glen knew that carrying the specific goods out had to pay the tax, and he worried about paying 22 for his watch. So when he was checked, he told a lie that his watch was a 23 fake (假货). When he was 24 of his “smarts”, immediately, in the presence of Glen, the officers hit the watch, 25 cost nearly 100,000, into pieces 26 hearing Glen’s words. Glen was 27 . Before he understood why, he was taken to the office to be examined 28 . For many times of entry-exit 29 he knew that only those people in the “blacklist” would “enjoy” this special treatment. The officers looked over everything carefully in the box, and 30 him no matter what time of entry and exit he must accept the check and if 31 reusing and carrying fake and shoddy goods, he would be 32 according to law! Suddenly, his face turned red, and he had nothing in mind after boarding the plane for long.After returning to the homeland, he often told the story to his family, and his employees, too. He said that this made a deep 33 on him, because the additional high “school” fee that he had ever paid made him realize the value of 34 , which he would remember as the 35 of his success forever.16. . set up B. took up C. went up D. picked up17. . honors B. mentions C. brings D. owes18. . decided B. refused C. objected D. asked19. . books B. things C. savings D. pounds20. . ordinary B. routine C. regular D. common21. . look B. inspection C. test D. experiment22. . one B. it C. them D. these23. . priceless B. useful C. worthless D. valuable24. . afraid B. proud C. ashamed D. hard25. . that B. what C. as D. which26. . on B. at C. who D. in27. . disappointed B. delighted C. amazed D. satisfied28. . strictly B. quietly C. quickly D. curiously29.

Consumers also worried that the nuclear plumes might spread to China by air and sea, polluting food sources, including salt taken from the sea.The wave of panic buying spread quickly across the country, driving up salt prices by five to ten fold in some cities.Even regions rich in salt production, like Jiangxi Province,faced sudden shortages.The government took measures to guarantee enough supply and to stabilize(稳定)the market. It also dismissed the nuclear rumors, saying the nuclear fallout was unlikely to reach the country, and that salt did not help to prevent radiation poisoning.Local authorities have stepped in to stabilize the market, too. As well, state-owned salt companies have been urged to increase their supply.Facing expanding market demand, distribution centers have taken extra measures to ensure they are well-prepared.Wang Yun, the General Manager of Beijing Salt Industry Corporation, said, "Our storage reserves can guarantee a two-month supply for the Beijing market."36.People made panic purchases of salt for the reasons EXCEPT______________.A. salt might protect them from po tential nuclear radiation. nuclear radiation might pollute food sourcesC. nuclear radiation might pollute salt taken from the seaD. there would be a shortage of salt on the market37.The underlined word “fold” in the third paragraph means _______.A. times . prices C. quantities D. means38.What measures did the government take for the panic buying?A. Enough salt would be offered to each house.. It admitted that salt could stop nuclear radiation.C. Authorities urged state-owned salt companies to increase the supply.D. Those who spread the rumor were all arrested and punished.39.What is the purpose of the writer to give the example of Beijing Salt Industry Corporation?A. To tell readers that there is a salt company in beijing.. To make people believe that the supply of salt is enough.C. To call on panic people to buy enough salt.D. To prove what the government did was right.Once many years ago, I pulled a family out of a burning car somewhere in Wyoming. Last week I received a telephone call from a woman who could not stop crying as she told me that one of my stories had saved her son from committing suicide. In closing she called me a hero.That got me thinking about what a hero is. Was I a hero because I pulled a family from a burning car? If so, how could I be a hero just because I wrote a story that saved someone’s life?Today I looked up the word “hero” in th e dictionary to see exactly what it meant. It read “a person who does something brave” and also “a person who is good and noble”.That statement impressed me more than the part about being brave. So I thought about something very important. And I remembered what happened to me years ago.After my marriage of twenty years ended, I was in such a condition. I was within hours trying to get up enough courage to end the pain and misery. Wh en I returned home, someone had sent me a card in the mail which told me how much they would appreciate me as a friend. That wonderful card probably saved my life. That person, without even knowing it, saved a life and became a hero.The many stories I kept writing in the following years saved the life of a teenage boy. In turn that makes the person who sent me the card a double hero. I suppose that is why I fight so hard to help the children now living in orphanages (孤儿院). Most children come out of these institutions with a very hard and bitter attitude against the world. The gifts we send them let them know that they have not been forgotten. Hopefully, most of them will never hurt anyone because of the kindness shown to them by those of us who cared. If it works, we will also become "heroes".40. The main idea of the passage is _______________.A. why the writer should be a hero . what a hero exactly isC. whether the writer is a heroD. that everyone is a hero41. Why did the woman call the writer a hero at the end of the call?A. ecause his story saved her so n’s life.. ecause he saved a family from a burning car.C. ecause he asked her son not to kill himself.D. ecause he was cute and kind to everybody.42. What does the underlined word “it” in the last sentence of Paragraph 5 refer to?A. The wonderful card the writer received 。
