Questions 47 to 51 are based on the following passage. When Toyota Motor Corp. moved one of its divisions into an environmentally friendly, or“green”, building in Torrance three years ago, it expected to save on its energy bills. The building offered natural lighting, electricity-generating rooftop solar panels and water recycling. But something else also happened. Employee morale jumped while absenteeism(旷工) fell. The overall energy and worker productivity savings more than offset the added cost of making the facility environmentally friendly. “The lighting is easier on the eyes and on the nerves, ”Toyota employee Mary Jo Moutsios said. “I take a sense of pride in working in this building. It’s pleasant and feels more productive. ” Results like Toyota’s are helping to spark a budding“green revolution”in American workplaces. The movement is starting to change how office buildings are designed and could render thousands of existing offices obsolete. Employers including Goldman, Sachs&Co. , Wal-Mart Stores Inc. and Harley-Davidson Inc. are starting to ask for buildings with more natural light, fresher air and fewer toxic materials in the paint, carpeting and other finishes. Los Angeles, Salt Lake City and Chicago are among many cities requiring new public buildings to be green. Municipalities are offering incentives, such as faster construction approvals and reduced permit fees, to get the private sector to follow suit. Although the green movement is in its infancy, its endorsement(认可) by a growing number of prestigious employers, developers and cities is seen as giving a shot in the arm to the nation’s environmental movement as concern about the effects of global warming and environmental pollution spread. More than $7.7 billion of office buildings nationwide are up for official green certification, versus about $790 million in 2000．Among the more notable new green towers is World Trade Center in New York. a 52-storey skyscraper that replaced a building at the same address that was destroyed in the 2001 terrorist attacks.

Questions 52 to 56 are based on the following passage. Most people think of lions as strictly African beasts, but only because they’ve been killed off almost everywhere else. Ten thousand years ago lions spanned vast sections of the globe. Now lions hold only a small fraction of their former habitat, and Asiatic lions, a subspecies that spit from African lions perhaps 100000 years ago, hang on to an almost impossibly small slice of their former territory. India is the proud steward of these 300 or so lions, which live primarily in a 560-square-mile sanctuary(保护区). It took me a year and a half to get a permit to explore the entire Gir Forest—and no time at all to see why these lions became symbols of royalty and greatness. A tiger will hide in the forest unseen, but a lion stands its ground, curious and unafraid—lionhearted. Though they told me in subtle ways when I got too close, Gir’s lions allowed me unique glimpses into their lives during my three months in the forest. It’s odd to think that they are threatened by extinction；Gir has as many lions as it can hold too many, in fact. With territory in short supply, lions move about near the boundary of the forest and even leave it altogether, often clashing with people. That’s one reason India is creating a second sanctuary. There are other pressing reasons：outbreaks of disease or natural disasters. In 1994 a serious disease killed more than a third of Africa’s Serengeti lions—a thousand animals a fate that could easily happen to Gir’s cats. These lions are especially vulnerable to disease because they descend from as few as a dozen individuals. “If you do a DNA test, Asiatic lions actually look like identical twins, ”says Stephen O’Brien, a geneticist(基因学家) who has studied them. Yet the dangers are hidden, and you wouldn’t suspect them by watching these lords of the forest. The lions display vitality, and no small measure of charm. Though the gentle intimacy of play vanishes when it’s time to eat, meals in Gir are not necessarily frantic affairs. For a mother and her baby lion sharing a deer, or a young male eating an antelope(羚羊), there’s no need to fight for a cut of the kill. The animals they hunt for food are generally smaller in Gir than those in Africa, and hunting groups tend to be smaller as well. The lions in the Gir Forest are especially vulnerable to disease because they______.
Every living thing has what scientists call a biological clock that controls behavior. It tells plants when to 62 flowers and insects when to leave protective cocoon(茧) and fly away. And it tells animals and human beings when to 63 , sleep and seek food. It controls our body temperatures, the 64 of some hormones and even dreams. Events 65 the plant and animal affect its actions. Scientists recently found that a tiny animal called Siberian hamster changes the color of its 66 because of the number of hours of 67 . In shorter days of winter its fur becomes white. The fur becomes gray-brown in longer 68 of daylight in summer. 69 signals control other biological clocks. German scientists found that some internal one seems to order birds to begin their 70 flights two times each year. Birds prevented from flying become 71 when it is time for the trip. 72 they become can again when the time of the flight has ended. A mix of outside and internal events controls some biological clocks；such things as heartbeat and the daily change from sleep to walking take place because of both external and internal signals. Scientists are beginning to learn 73 parts of the brain contain the biologicaI clocks. A researcher at Harvard University. Dr. Martin Moore Ede, said a small group of cells near the front of the brain seemed to control the 74 of some of our actions. Probably there are other cells to control other body activities. He is studying 75 they affect the way we do our work. Most of us have great difficulty if we 76 often change to different work hours. 77 call take many days for a human body to 78 a major change in work hours. Industrial officials should have a better 79 of biological clocks and how they affect workers. He said such an understanding could 80 sickness and accidents at work, and would help increase 81 .
