Passage 4Plant adaptation can be remarkably complex. Certain species of orchids, for instance, imitate female bees, other plants look and smell like animals, and still others have the appearance of stone. These strange adaptations to life represent just a few of the sophisticated means by which plants enhance their chances of survival.Mimicry in plants or animals is a three-part system. There is a model; the animal, plant, or substrate being imitated. There is a mimic; the organism that imitates the model. And there is a signal receiver or dupe; the animal that cannot effectively distinguish between the model and the mimic. Mimetic traits may include morphological structures, color patterns, behaviors, or other attributes of the mimic that promote its resemblance to a model. That model may be either an unrelated species or an inanimate objects such as the background against which an organism spends most of its time.Mimicry is not an active strategy on the part of an individual plant; flowers do no deliberately trick or deceive animals into visiting them. Mimicry arises as the result of evolution through natural selection and the occurrence of random generic mutations that lead over many generations to the appearance of favorable characteristics. If such traits help to camouflage a plant, for example, the plant is likely to have survival advantage over other plants that are less well camouflaged. The plant will leave more descendants, thereby passing the advantage to the next generation. For natural selection to favor the evolution of mimicry, the mimic must derive a reproductive advantage from modeling itself after another organism or object; its fitness, measured as the number of offspring produced that survive into the next generation must be increased as the result of deception. The word "camouflage" (in line 4, para. 3) most probably means （）
Passage 3The period of adolescence, i.e, the period between childhood and adulthood, maybe long or short, depending on social expectations and on society’s definition as to what constitutes maturity and adulthood. In primitive societies adolescence is frequently a relatively short period of time, while in industrial societies with pattems of prolonged education coupled with laws against child labor, the period of adolescence is much longer and may include most of the second decade of one’s life. Furthermore, the length of the adolescent period and the definition of adulthood status may change in a given society as social and economic conditions change. Examples of this type of change are the disappearance of the frontier in the latter part of the nineteenth century in the United States, and more universally, the industrialization of an agricultural society.In modern society, ceremonies of adolescence have lost their formal recognition and symbolic significance and there no longer is agreement as to what constitutes initiation ceremonies. Social ones have been replaced by a sequence of steps that lead to increased recognition and social status. For example, grade school graduation, high school graduation and college graduation constitute such a sequence, and while each step implies certain behavioral changes and social recognition. The significance of each depends on the social-economic status and the educational ambition of the individual. Ceremonies for adolescence have also been replaced by legal definitions of status roles, rights, privileges and responsibilities. It is during the nine years from the twelfth birthday to the twenty-first that the protective and restrictive aspects of childhood and minor status are removed and adult privileges and responsibilities are granted. The twelve-year-old is no longer considered a child and has to pay full fare for train, airplane, theater and movie tickets. Basically, the individual at this age loses childhood privileges without gaining significant adult rights. At the age of sixteen the adolescent is granted certain adult rights which increase his social status by providing him with more freedom and choices. He now can obtain a driver’s license; he can leave public schools; and he can work without the restrictions of child labor laws. At the age of eighteen the law provides adult responsibilities as well as rights. The young man can now be a soldier, he also can marry without parental permission. At the age of twenty-one the individual obtains his full legal rights as an adult. He now can vote, he can buy liquor, he can enter into financial contracts, and he is entitled to run for public office. No additional basic rights are acquired as a function of age after majority status has been attained. None of these legal provisions determine at what point adulthood has been reached but they do point to the prolonged period of adolescence. According to the passage, it is true that().

These 40 leading industrialized countries emitted 2.3 percent more greenhouse gases (GHG) from 2000 to 2006. Massive floods deep below Antarctica’s ice cover are accelerating the flow of glaciers into the sea. These two pieces of news came a couple of weeks before the Dec. 1 UN Climate Change Conference in Poznan, Poland. But unfortunately they went almost unnoticed in the media busy as they were grappling with the global financial crises. Call it quirk of the modem world’s fate, or our incapability to look beyond the immediate. We are so ensconced in the comforts of our times that nothing beyond the immediate can break our stupor. R’s true, global warming made a few headlines before the financial crisis spread its wings from the US and cast a shadow of gloom over the rest of the world. But our response has always been knee-jerk.
