2 阅读理解。 A newly-wedded couple on a four-month honeymoon were hit by six natural disasters, including the Australian floods, Christchurch earthquake and Japanese tsunami (海啸). Stefan and Erika Svanstrom left Stockholm, Sweden, on December 6 and were immediately stranded (搁浅) in Munich, Germany, due to one of Europe"s worst snowstorms. Travelling with their baby daughter, they flew on to Cairns in Australia which was then struck by one of the most violent cyclones in the nation"s history. From there, the couple, in their 20s, were forced to shelter for 24 hours on the cement (水泥) floor of a shopping centre with 2,500 others. "Trees were being knocked over and big branches were put down across the streets," Mr. Svanstrom told Sweden"s Expressen newspaper. "We escaped by the skin of our teeth." Mr. Svanstrom said they then headed south to Brisbane but the city was experiencing massive flooding, so they crossed the country to Perth where they narrowly escaped burning bush fires. The couple then flew to Christchurch, New Zealand, arriving just after a massive magnitude (震级) 6.3 earthquake attacked the city on February 22. Mrs. Svanstrom said, "When we got there the whole town was a war zone. We could not visit the city since it was completely blocked off, so instead we travelled around before going to Japan." But days after the Svanstroms arrived, Tokyo was rocked by Japan"s largest earthquake since records began. "The trembling was horrible and we saw roof tiles fly off the buildings," Mr. Svanstrom said. "It was like the buildings were swaying back and forth." The family returned to Stockholm on March 29 after a much calmer visit to their last destination China. But Mr. Svanstrom -who also survived the devastating (毁灭性的) Boxing Day tsunami that hit southeast Asia in 2004 -said the marriage was still going strong. He added, "I know marriages have to experience some difficulties, but I think we have been through most of them. We"ve certainly experienced more than our fair share of disasters, but the most important thing is that we"re together and happy." 1.The best title for this passage is _________. A. Meeting Disasters During Honeymoon B. Six Natural Disasters C. Newly-wed Couple Met Australian Floods D. Japanese Tsunami 2. Why were Stefan and Erika Svanstrom stopped in Munich? A. Christchurch earthquake stopped them. B. Because of Europe"s worst snowstorm. C. The plane was damaged. D. The Svanstroms didn"t experience any disaster in China. 4. The Svanstroms thought that Christchurch of New Zealand was ________. A. disordered B. interesting C. beautiful D. shaking 5. In Svanstrom"s opinion, a marriage _______. A. has to go peacefully and happily for all time B. has to experience many disasters at the beginning C. must always allow the couple be together and happy D. should experience difficulties to make it steady

9 阅读理解。 It was the summer of 1965. DeLuca, then 17, visited Peter Buck, a family friend. Buck asked DeLuca about his plans for the future. "I"m going to college, but I need a way to pay for it," DeLuca recalls saying. "Buck said, "You should open a sandwich shop."" That afternoon, they agreed to be partners. And they set a goal: to open 32 stores in ten years. After doing some research, Buck wrote a check for $1000. DeLuca rented a storefront (店面) in Connecticut, and when they couldn"t cover their start-up costs, Buck kicked in another $1000. But business didn"t go smoothly as they expected. DeLuca says, "After six months, we were doing poorly, but we didn"t know how badly, because we didn"t have any financial controls." All he and Buck knew was that their sales were lower than their costs. DeLuca was managing the store and going to the University of Bridgeport at the same time. Buck was working at his day job as a nuclear physicist in New York. They"d meet Monday evenings and brainstorm ideas for keeping the business running. "We convinced ourselves to open a second store. We figured we could tell the public, "We are so successful, we are opening a second store." And they did-in the spring of 1966. Still, it was a lot of learning by trial and error. But the partners" learn-as-you-go approach turned out to be their greatest strength. Every Friday, DeLuca would drive around and hand-deliver the checks to pay their suppliers. "It probably took me two and a half hours and it wasn" t necessary, but as a result, the suppliers got to know me very well, and the personal relationships established really helped out," DeLuca says. And having a goal was also important. "There are so many problems that can get you down. You just have to keep working toward your goal," DeLuca adds. DeLuca ended up founding Subway Sandwich, the multimillion-dollar restaurant chain. 1. DeLuca opened the first sandwich shop in order to ____. A. support his family B. pay for his college education C. help his partner expand business D. do some research 2. Which of the following is true of Buck? A. He put money into the sandwich business. B. He was a professor of business administration. C. He was studying at the University of Bridgeport. D. He rented a storefront for DeLuca. 3. What can we learn about their first shop? A. It stood at an unfavorable place. B. It lowered the prices to promote sales. C. It made no profits due to poor management D. It lacked control over the quality of sandwiches 4. They decided to open a second store because they ___. A. had enough money to do it. B. had succeeded in their business C. wished to meet the increasing demand of customers D. wanted to make people believe that they were successful 5. What contribute most to their success according to the author? A. Learning by trial and error. B. Making friends with suppliers. C. Finding a good partner. D. Opening chain stores.
