    Directions: Read the following passage. Answer the questions according to the information given in the passage and required words limit. Write your answers on your answer sheet.
    The tasty cream-filled golden sponge(海绵) cakes have been an American favorite for decades. These are just a few of the sugary treats made by the beloved Hostess brand. But after more than 80 years, Americans have to say goodbye to these iconic (标志性的) desserts. Early last week, Hostess announced it is going out of business.
    "Many people have worked unbelievably long and hard to keep this from happening," said Hostess CEO Gregory F. Rayburn. "Hostess Brand has no other alternative than to begin the process of getting down and preparing for the sale of our iconic brands." Along with Twinkles (奶油蛋糕) and Wonder Bread, cupcakes and other sugary treats may disappear from the shelves.
    In the past decade, Hostess has experienced difficulties with its management and high labor costs. The company had money troubles in the past, but this time there was no way to recover. Along with the loss of sugary treats comes the loss of nearly 20,000 jobs. Hostess fans hope that another company will buy out the Hostess.
    The downfall of Hostess is due not just to the company's financial problems, but also to a changing America. Our country's tastes and lifestyles are not the same as they were eighty years ago. Americans have become more health-conscious, and they are demanding more healthful food products. As a manufacturer of high-calorie products, Hostess does not fit into this new way of life.
    To make matters worse for Hostess, Americans do not eat as much bread as they once did. "More and more people are choosing one-dish meals," said Harry Balzar. "The tradition of bread as a side dish is going out." Americans are finding alternatives to their morning toast too. Instead they’re choosing quick snacks like yogurt and energy bars.
    Will Twinkles become an image of a bygone(过去的) America? Hostess fans hope that it will secure its spot on supermarket shelves for years to come. We can only wait. And maybe eat fruit for dessert instead.
    小题1:What caused Hostess to be in trouble in the last 10 years? (no more than 7 words)
    _____________________________________________________________________
    小题2:Can you list three disappearing sugary desserts by Hostess? (no more than 5 words)
    _____________________________________________________________________
    小题3:What makes Hostess's situation more severe? (no more than 9 words)
    _____________________________________________________________________
    小题4:What's the hope of Hostess fans about this spongy snack's future? (no more than 20 words)
    _____________________________________________________________________

    Dos and don’ts on physical activity:
    Heart patients must also know that they can do most of the activities where the heart rate does not go up. Sitting in an office, talking over the phone, discussing, driving car are some of the activities which do not increase the heart’s speed.     小题5:   As a matter of fact, stresses can also lead to other illnesses.
