Passage 1 DJH,#re>
As the horizons of science have expanded, two main groups of scientists have emerged. One is the pure scientist; the other, the applied scientist. Olq`mlsK
The pure or theoretical scientist does original research in order to understand the basic laws of nature that govern our world. The applied scientist adapts this knowledge to practical problems. Neither is more important than the other, however, for the two groups are very much related. Sometimes, however, the applied scientist finds the "problem" for the theoretical scientist to work on. Let's take a particular problem of the aircraft industry: heat-resistant metals. Many of the metals and alloys which perform satisfactorily in a car cannot be used in a jet-propelled plane. New alloys must be used, because the jet engine operates at a much higher temperature than an automobile engine. The turbine wheel in a turbojet must withstand temperatures as high as 1,600 degrees Fahrenheit, so aircraft designers had to turn to the research metallurgist for the development of metals and alloys that would do the job in jet-propelled planes. WQY\R!+
Dividing scientists into two groups is only one broad way of classifying them, however. When scientific knowledge was very limited, there was no need for men to specialize. Today, with the great body of scientific knowledge, scientists ? [i]%PVGW
specialize in many different fields. Within each field, there is even further subdivision. And, with finer and finer subdivisions, the various sciences have become more and more interrelated until no one branch is entirely independent of the' others. Many new specialties --geophysics and biochemistry, for example -- have resulted from combining the knowledge of two or more sciences. mp0!S

In The Disuniting of America: Reflections on a Multicultural Society, Revised and Enlarged Edition (W. W. Norton) Schlesinger provides deep insights into the crises of nationhood in America. A new chapter assesses the impact both of radical multiculturalism and radical monoculturalism on the Bill of rights. Written with his usual clarity and force, the book brings a noted historian's wisdom and perspective to bear on America's "culture wars". R{Qvpd$y
Schlesinger addresses the questions: What holds a nation together? And what does it mean to be an American? Describing the emerging cult of ethnicity, Schlesinger praises its healthy effect on a nation long shamed by a history of prejudice and narrow-mindedness. But he warns against the campaign of multicultural advocates to divide the nation into separate ethnic and racial communities. From the start, he observes, the United States has been a multicultural nation, rich in its diversity but held together by a shared commitment to the democratic process and by the freedom of intermarriage. It was this national talent for assimilation that impressed foreign visitors like Alexis de Tocqueville and James Bryce, and it is this historic goal that Schlesinger champions as the best hope for the future. Schlesinger analyzes what sh8(+hg
he sees as grim consequences of identity politics: the widening of differences. Attacks on the First Amendment, he argues, threaten intellectual freedom and, ultimately, the future of the ethnic groups. His criticisms are not limited to the left. As a former target of McCarthyism, he understands that the radical right is even more willing than the radical left to restrict and weaken the Bill of Rights. ),+u>Os&
The author does not minimize the injustices concealed by the "melting pot" dream. The Disuniting of America is both academic and personal, forceful in argument, balanced in judgment. It is a book that will no doubt anger some readers, but it will surely make all of them think again. The winner of Pulitzer Prizes for history and for biography, an authoritative voice of American liberalism, Schlesinger is uniquely positioned to bring bold answers and healing wisdom to this passionate debate over who we are and what we should become.

Passage 3 (g@e=m7Q
The El Nino ("little boy" in Spanish) that pounded the globe between the summers of1997 and 1998 was in some measure the most destructive in this century. Worldwide damage estimates exceed ~20 billion --not to mention the human death toll caused by resulting droughts, floods and bushfires. El Nino and La Nina ("little girl") are part of a seesawing of winds and currents in the equatorial Pacific called ENSO (El Nino Southern Oscillation) that appears every two to eight years. Normally, westward-blowing trade winds caused by the rotation of the earth and conditions in the Tropics push surface water across the Pacific towards Asia. The warm water piles up along the coasts of Indonesia, Australia and the Philippines, raising sea levels more than a foot above those on the South American side of the Pacific. As El Nino builds the normal east-to-west trade winds wane. Like water splashing in a giant bathtub, the elevated pool of warm water washes from Asian shores back towards South America. b]h]h1~hHH
In last season's cycle, surface temperatures off the west coast of South America soared from a normal high of 23°C degrees to 28°C degrees. This area of warm water, twice the size of the continental US, interacted with the atmosphere, creating storms and displacing high-altitude winds. El Nino brought rain that flooded normally dry coastal areas of Ecuador, Chile and Peru, while droughts struck Australia and Indonesia. Fires destroyed some five million acres of Indonesian forest. The drought, along with the economic crisis, left about five million people desperate for food and water. These conditions helped set the stage for riots that led to the downfall of President Suharto. El Nino also took the blame for extreme temperatures in Texas last summer over 38°C degrees for a record 30 days in a row. In Florida, lush vegetation turned to tinder and bushfires raged. Even Britain has been sweltering with our hottest year on record in 1997. o=
