Text 2 This election year, the debate over cloning technology has become a circus—and hardly anybody has noticed the gorilla hiding in the tent. Even while President Bush has, endorsed throwing scientists in jail to stop "reckless experiments", it’s just possible the First Amendment will protect researchers who want to perform cloning research. Dr. Leon Kass, the chairman of the President’s Council on Bioethics, would like to keep that a secret. "I don’t want to encourage such thinking," he said. But the notion that the First Amendment creates a "right to research" has been around for a long time, and Kass knows it. In 1977, four eminent legal scholars—Thomas Emerson, Jerome Barton, Walter Berns and Harold P. Green—were asked to testify before the House Subcommittee on Science, Technology and Space. At the time, there was alarm in the country over recombinant DNA. Some people feared clones, designer babies,
A. identical.
B. similar.
C. complementary.
D. opposite.

Text 3 In the angry debate over how much of IQ comes from the genes that children inherit from parents and how much comes from experiences, one little fact gets overlooked: no one has identified any genes (other than those in the case of retardation) that affect intelligence. So researchers led by Robert Plomin of London’s Institute of Psychiatry decided to look for some. Plomin’s colleagues drew blood from two groups of 51 children each. They are all White living in six counties around Cleveland. In one group, the average IQ is 136. In the other group, the average IQ is 103. Isolating the blood cells, the researchers then examined each child’s chromosome 6 ( One of 23 human chromosomes along which genes made of DNA). Of the 37 landmarks on chromo- some 6 that the researchers looked for, one jumped out: a form of gene called IGF2R occurred in twice as many children in high-IQ group as in the average group -- 32 percent versus 16 percent. The survey conclu
A. questioningly.
B. willingly.
C. publicly.

Over the last twenty years, scholarly and popular writers have analyzed and celebrated the worlds of leisure and entertainment in the burgeoning cities of mid-nineteenth-century America, greatly expanding the literature on these subjects. They have found an enthusiastic readership by offering glimpses of modes of leisure, performance, and charlatanism that passed from the scene in the early 20th century, indicating how lively they were and how comparatively impoverished our own entertainment choices have become in an era dominated by corporate electronic media.
Many scholars have been lured into a fascination with the extinct demimonde of dime museums, exhibition hails, saloons, and industrial exhibitions. During this period entertainment relied upon artful deception, comparable in importance to such contemporary forms of amusement as minstrelsy and melodrama. The cultural activities were forms of representational play in which spectators are caused
A. melodrama.
B. double consciousness.
C. electronic media,
D. artful deception.

Over the past few decades, there has been a considerable increase in the use of mathematical analysis, both for solving everyday problems and for theoretical developments of many disciplines. For example, economics, biology, geography and medicine have all seen a considerable increase in the use of quantitative techniques. Twenty years ago applied mathematics meant the application of mathematics to problems in mechanics and little else--now, applied mathematics, or as many people prefer to call it, applicable mathematics, could refer to the use of mathematics in many varied areas. The one unifying theme that these applications have is that of mathematical modeling, by which we mean the construction of a mathematical model to describe the situation under study. This process of changing a real life problem into a mathematical one is not at all easy, we hasten to add, although one of the overall aims of this book is to improve your ability as a mathematical mod
