At those times, his large Norwegian frame shook with laughter while he pretended innocent surprise, exclaiming, “Oh, forevermore！” But on a cold Saturday in downtown Chicago, Grandpa felt that God played a trick on him, and Grandpa wasn't laughing.‎ Grandpa worked as a carpenter. On this particular day, he was building some boxes for the clothes his church was sending to an orphanage abroad. On his way home, he reached into his shirt pocket to find his glasses, but they were gone. He remembered putting them there that morning, so he drove back to the church. His search proved fruitless.‎ Suddenly, he realized what happened. The glasses had slipped out of his pocket unnoticed and fallen into one of the boxes, which he had nailed shut. His brand new glasses were heading for China!‎ The Great Depression was at its height, and Grandpa had six children. He had spent twenty dollars for those glasses that very morning.‎ ‎“It's not fair，” he told God as he drove home in frustration. “I've been very faithful in giving of my time and money to your work, and now this.”‎ Several months later, the director of the orphanage was on vacation in the United States. He wanted to visit all the churches that supported him, so he came to speak on Sunday night at my grandfather's small church in Chicago. Grandpa and his family sat in their usual seats among the small congregation (教堂会众)．‎ ‎“But most of all，” he said, “I must thank you for the glasses you sent last year.”‎ ‎“Even if I had the money, there was simply no way of replacing those glasses. Along with not being able to see well, I experienced headaches every day, so my coworkers and I were much in prayer about this. Then your boxes arrived. When my staff removed the covers, they found a pair of glasses lying on the top.” After a long pause, he continued, “Folks, when I tried on the glasses, it was as though they had been custom—made just for me! I want to thank you for being a part of that！”‎ The people listened, happy for the amazing glasses. But the director surely must have confused their church with another; they thought, there were no glasses on their list of items to be sent overseas.‎ But sitting quietly in the back, with tears streaming down his face, an ordinary carpenter realized the Master Carpenter had used him in an ‎ extraordinary way.‎ ‎1. Which of the following is NOT true about Grandpa Nybakken according to the passage?‎ A. He was an outgoing man and held an active attitude towards life.‎ B. He had a large family to support.‎ C. He was a carpenter working in the church.‎ D. He was a loyal Christian.‎ 答案及解析：‎ ‎1. C。 A选项根据第一段可以判断，B选项根据Grandpa had six children可以判断，D选项根据I've been very faithful in giving of my time and money to your work可以判断。文章第二段只是表明祖父是个木匠，那天只是在教堂帮帮忙，并没有说他在那工作。 ‎ ‎2. Grandpa spent much of his time and money in church mainly to ______.‎ ‎ A. help the priest do some religious work ‎ B. help those people in need C. make some woodwork for the church D. seek some help from God 答案及解析：‎ ‎2. B。根据文章可以知道祖父信仰上帝，而上帝的工作就是福泽人们，所以他会去帮助别人。A在文章中没有提及，C、D不是祖父的目的。‎ ‎3. The people in the church but Grandpa felt confused at what the director said because ______.‎ A. Grandpa didn't tell the director that he was the owner of the glasses B. the director wanted to return the glasses even though he liked it ‎ C. the director could not get such glasses in their own country D. the glasses were not included in the donation list 答案及解析：‎ ‎3. D。根据there were no glasses on their list of items to be sent overseas” 可以判断。‎ ‎4. Who does “the Master Carpenter” in the last paragraph probably refer to?‎ A. Grandpa's master. ‎ B. One of Grandpa's friends. ‎ C. God.‎ D. Grandpa's coworker.‎ 答案及解析：‎ ‎4. C。答案与文章第一段中的Grandpa felt that Godplayed a trick on him相照应，最后一段中的an ordinary carpe ‎ nter指的就是祖父，the Master Carpenter指的是God，耶稣也曾是木匠。‎ ‎5. Which can be the best title of the passage?‎ A. Grandfather's Life ‎ B. The Helpful Donation C. The Perfect Mistake D. An Impressive Speech 答案及解析：‎ ‎5. C。根据文章的描述，祖父因为不小心把眼镜掉进了运送募捐物品的箱子中，然而这副眼镜却给了受捐赠者极大的帮助。所以这是一次“美丽的失误”。‎ B ‎ The largest earthquake (magnitude里氏 9.5) of the 20th century happened on May 22, 1960 off the coast of South Central Chile. ‎ ‎ It generated(生成) one of the most destructive Pacificwide tsunamis(海啸). Near the generating area, both the earthquake and the tsunami were very much destructive, particularly in the coastal area from Concepcion to the south end of Isla Chiloe. ‎ The largest tsunami damage occurred at Isla Chiloe－the coastal area closest to the epicenter(震中). Huge tsunami waves measuring as high as 25 meters arrived within 10 to 15 minutes after the earthquake, killing at least two hundred people, sinking all the boats, and flooding half a kilometer inland. ‎ There was large damage and loss of life at Concepcion, Chile's top ‎ industrial city. Near the city of Valdivia, the earthquake and following aftershocks generated landslides which killed 18 people. At the port city of Valparaiso, a city of 200 000, many buildings collapsed. A total of 130 000 houses were destroyed－one in every three in the earthquake zone and nearly 2 000 000 people were left homeless. ‎ Total damage losses, including to agriculture and to industry, were estimated(估计) to be over a half billion dollars. The total number of death related with both the tsunami and the earthquake was never found accurately for the region. Estimates of deaths reached between 490 to 57 002 with no distinction(差别) as to how many deaths were caused by the earthquake and how many were caused by the tsunami. However, it is believed that most of the deaths in Chile were caused by the tsunami.‎ ‎6. Where did the largest tsunami damage occurred?‎ A. Concepcion. ‎ B. Isla Chiloe.‎ C. Valdivia. ‎ D. Valparaiso. ‎ 答案及解析：‎ ‎6．B。细节题。从文章第二段第三句“The largest tsunami damage occurred at Isla Chiloe－the coastal area closest to the epicenter(震中)．”可以得到答案。‎ ‎7. What can we learn about the tsunami waves generated by the earthquake?‎ ‎ A. The tsunami waves as high as 25 meters arrived immediately after the earthquake.‎ ‎ B. The tsunami waves killed 200 people and sank all boats.‎ ‎ C. The tsunami waves were very destructive.‎ ‎ D. The tsunami waves flooded half of the inland.‎ 答案及解析：‎ ‎7．C。本题为细节题，考查文章第二段的最后几句。海啸不是arrived immediately而是10～15分钟以后到来，至少200人死于海啸，海啸淹没了half a kilometer inland，故A、B、D3个选项均有误。‎ ‎8. What is generally thought the main cause of deaths in Chile? ‎ A. Landslides.‎ B. The tsunami.‎ C. Aftershocks.‎ D. The magnitude 9.5 earthquake.‎ 答案及解析：‎ ‎8．B。最后一段的最后一句However, it is believed that most of the deaths in Chile were caused by the tsunami.说明本题答案。‎ ‎9. What is the total number of deaths in the earthquake?‎ A. 2 000 000. ‎ B. Between 490 and 57 002.‎ C. 200 000. ‎ D. It was hard to know.‎ 答案及解析：‎ ‎9．D。细节题。2 000 000为无家可归人的数目；200 000为the city of Valparaiso的人口数；490 to 57 002为地震和海啸共同导致的死亡数。‎ ‎10. What does the underlined word “collapsed” probably mean?‎ A. Was destroyed. ‎ B. Caught fire. ‎ C. Was flooded. ‎ D. Sank. ‎ 答案及解析：‎ ‎10．A。由本段的下一句“A total of 130 000 houses were destroyed...”可以推测出答案。‎
