There is a growing feeling that science, especially what is known as the new physics, can provide answers where religion remains vague and faltering. Many people in search of a meaning to their lives are finding enlightenment in the revolutionary developments at the frontiers of science. Much to the bewilderment of professional scientists, quasi-religious cults are being formed around such unlikely topics as quantum physics, space-time relativity, black holes and the big hang.
How can physics, with its reputation for cold precision and objective materialism, pro- vide such fertile soil for the mystical？ The truth is that the spirit of scientific inquiry has undergone a remarkable transformation over the past 50 years. The twin revolutions of the theory of relativity, with its space-warps and timewarps, and the quantum theory, which reveals the shadowy and unsubstantial nature of atoms, have demolished the classical image of a clockwork universe slavishly unfolding along a predetermined pathway. Replacing this sterile mechanism is a world full of shifting indeterminism and subtle interactions which have no counterpart in daily experience.
To study the new physics is to embark on a journey of wonderment and paradox, to glimpse the universe in a novel perspective, in which subject and object, mind and matter, force and field, become intertwined. Even the creation of the universe itself has fallen within the province of scientific inquiry.
The new cosmology provides, for the first time, a consistent picture of how all physical structures, including space and time, came to exist out of nothing. We are moving towards an understanding in which matter, force, order and creation are unified into a single descriptive theme.
Many of us who work in fundamental physics are deeply impressed by the harmony and order which pervades the physical world. To me the laws of the universe, from quarks to quasars, dovetail together so felicitously that the impression there is something behind it all seems overwhelming. The laws of physics are so remarkably clever they can surely only be a manifestation of genius.
Scientists find the new cults bewildering because they are______.
A．too reactionary
B．based on false evidence
C．derived from inappropriate sources
D．too subjective

The author says people nowadays find that traditional religion is ______.
A．a form. of reassurance
B．inadequate to their needs
C．responding to scientific progress
D．developing in strange ways
Moreover, an outcry for a fresher, more practical, and more advanced kind of instruction arose among the alumni and friends of nearly all of the old colleges and grew into a movement that overrode all conservative opposition. The aggressive "Young Yale" movement appeared, demanding partial alumni control, a more liberal spirit, and a broader course of study. The graduates of Harvard College simultaneously rallied to relieve the college's poverty and demand new enterprise. Education was pushing toward higher standards in the East by throwing off church leadership everywhere, and in the West by finding a wider range of studies and a new sense of public duty.
The old-style. classical education received its most crushing blow in the citadel of Harvard College, where Dr. Charles Eliot, a young captain of thirty-five, son of a former treasure of Harvard, led the progressive forces. Five revolutionary advances were made during the first years of Dr. Eliot's administration. They were the elevation and amplification of entrance requirements, the enlargement of the curriculum and the development of the elective system, the recognition of graduate study in the liberal arts, the raising of professional training in law, medicine, and the fostering of greater maturity in student life. Standards of admission were sharply advanced in 1872 - 1873 and 1876 ~ 1877. By the appointment of a dean to take charge of student affairs, and a wise handling of discipline, the undergraduates were led to regard themselves more as young gentlemen and less as young animals. One new course of study after another was opened up: science, music, the history of the fine arts, advanced Spanish, political economy, physics, classical philology, and international law.
Which of the following is the author's main purpose in writing the passage？
A．To present the history of Harvard College and compare it with that of Yale University.
B．To criticize the conditions of the U. S. universities in the 19th century.
C．To describe innovations in the U. S. higher education in the late 180Os.
D．To introduce what was happening in major U. S. universities before the turn of the century.

To produce the upheaval in the United States that changed and modernized the domain of higher education from the mid-1860's to the mid-1880's, three primary causes interacted. The emergence of a half-dozen leaders in education provided tile personal force that was needed. Moreover, an outcry for a fresher, more practical, and more advanced kind of instruction arose among tile alumni(校友) and friends of nearly all of the old colleges and grew into a movement that overrode all conservative opposition. The aggressive "Young Yale" movement appeared, demanding partial alumni control, a more liberal spirit, and a broader course of study. Tile graduates of Harvard College simultaneously rallied to relieve the college's poverty and demand new enterprise.

Five revolutionary advances were made during the first years of Dr. Eliot's administration. They were the elevation(提高) and amplification(增加) of entrance requirement, the enlargement of the curriculum and the development of the elective system, the recognition of graduate study in the liberal arts, the raising of professional training in law, medicine, and engineering to a postgraduate level, and the fostering of greater maturity in student life.

It can be inferred from the passage that if the educational revolution had not taken place during the period between the mid-160's and the mid-10's, Harvard College ______.
A．would have been one of the colleges which enjoy the greatest fame in the United States
B．would have been a model of the old-style. classical colleges in the United States
C．would not have been so famous and enjoyed the fame it now has today
D．would have been emerged with the Yale University to become a larger one
One might expect that the vacuum would always be the state of the lowest possible energy for a given region of space. If an area is initially empty and a real panicle is put into it, the total energy, it seems, should be raised by at least the energy equivalent of the mass of the added panicle. A surprising result of some recent theoretical investigations is that this assumption is not invariably true. There are conditions under which the introduction of a real particle of finite mass into an empty region of space can reduce the total energy, If the reduction in energy is great enough, an electron and a positron will be instantly created. Under these conditions the electron and positron are not a result of vacuum fluctuations but are real particles, which exist indefinitely and can be detected. In other words, under these conditions the vacuum is an unstable state and can decay(衰减) into a state of lower energy; that is one in which real particles are created.
The necessary condition for the decay of the vacuum is the presence of an intense electric field. As a result of the decay of the vacuum, the space permeated by such a field can be said to obtain an electric charge, and it can be called a charged vacuum. The particles that materialize in space make the charged vacuum likely to be found in only one place: in the immediate vicinity of a super heavy atomic nucleus(原子核), one with about twice as many pro tons as the heaviest natural nuclei known. A nucleus that large cannot be stable, but it might be possible to assemble one next to a vacuum for long enough to observe the decay of the vacuum. Experiments attempting to achieve this are now under way.
Which of the following titles best describes the passage as a whole？
A．The Vacuum: Its Fluctuations and Decay.
B．The Vacuum: Its Creation and Instability.
C．The Vacuum: a State of Absence.
D．Particles that Materialize in the Vacuum.
