For decades, Americans have taken for granted the United States’ leadership position in the development of new technologies. The innovations (创新) that resulted from research and development during World War II and afterwards were 36 to the prosperity of the nation in the second half of the 20th century. Those innovations, upon which virtually all aspects of 37 society now depend, were possible because the United States then 38 the world in mathematics and science education. Today, however, despite increasing demand for workers with strong skills in mathematics and science, the 39 of degrees awarded in science, math, and engineering are decreasing.
The decline in degree production in what are called the STEM disciplines (science, technology, engineering, and math) seems to be 40 related to the comparatively weak performance by U.S. schoolchildren on international assessments of math and science. Many students entering college have weak skills in mathematics. According to the 2005 report of the Business-Higher Education Forum, 22 percent of college freshmen must take remedial (补习的) math 41 , and less than half of the students who plan to major in science or engineering 42 complete a major in those fields.
The result has been a decrease in the number of American college graduates who have the skills, 43 in mathematics, to power a workforce that can keep the country at the forefront (前沿) of innovation and maintain its standard of living. With the 44 performance of American students in math and science has come increased competition from students from other countries that have strongly supported education in these areas. Many more students earn 45 in the STEM disciplines in developing countries than in the United States.
A) accelerating
B) actually
C) closely
D) contemporary
E) courses
F) critical
G) declining
H) degrees
I) especially
J) future
K) led
L) met
M) procedures
N) proportions
O) spheres

The telecity is a city whose life, direction, and functioning are largely shaped by telecommunications. In the twenty first century, cities will be based more and more on an economy that is dependent on services and intellectual property. Telecommunications and information networks will define a city's architecture, shape, and character. Proximity in the telecity will be defined by the speed and bandwidth of networks as much as by geographical propinquity. In the age of the telecity, New York and Singapore may be closer than, say, New York and Arkadelphia, Arkansas.
Telecities will supersede megacities for several reasons, including the drive toward clean air, reducing pollution, energy conservation, more jobs based on services, and coping with the high cost of urban property. Now we must add the need to cope with terrorist threats in a high-technology world.
Western mind-sets were clearly jolted in the wake of the terrorist attack on the World Trade Center in New York City and attacks in Indonesia, Saudi Arabia, and else where. But the risks posed by twentieth-century patterns of urbanization and architecture have ye to register fully with political figures and leaders of industry. The Pentagon, for example, has been rebuilt in situation rather than distributed to multiple locations and connected by secure landlines and broadband wireless systems. Likewise, the reconstruction of the World Trade Center complex still represents a massive concentration of humanity and infrastructure. This is a remarkably shortsighted and dangerous vision of the future.
The security risks, economic expenses, and environmental hazards of over-centralization are everywhere, and they do not stop with skyscrapers and large governmental structures. There are risks also at seaports and airports, in food and water supplies, at nuclear power plants and hydroelectric turbines at major dams, in transportation systems, and in information and communications systems.
This vulnerability applies not only to terrorist threats but also to human error, such as system-wide blackouts in North America in August 2003 and in Italy in September 2003, and natural disasters such as typhoons, hurricanes, floods, and earthquakes. Leaders and planners are only slowly becoming aware that overcentralized facilities are the most vulnerable to attack or catastrophic destruction.
There is also growing awareness that new broadband electronic systems now allow governments and corporations to safeguard their key assets and people in new and innovative ways. So far, corporations have been quickest to adjust to these new realities, and some governments have begun to adjust as well.
Which of the following statements is true according to the passage？
A．The telecity is a TV manufacturing city.
B．The telecity is a city of the speed and bandwidth of networks.
C．Singapore is closer to New York than Arkadelphia, Arkansas is in telecity age.
D．Singapore is actually closer to New York than Arkadelphia, Arkansas.

Is language, like food, a basic human need without which a child at a critical period of life can be starved and damaged？ Judging from the drastic experiment of Frederick Ⅱ in the thirteenth century, it may be. Hop hag to discover what language a child would speak if he heard no mother tongue, he told the nurses to keep silent.
All the infants died before the first year. But clearly there was more than lack of language here. What was missing was good mothering. Without good mothering, ill the first year of life especially, the capacity to survive is seriously affected.
Today no such severe lack exists as that ordered by Frederick. Nevertheless, some children are still backward in speaking. Most often the reason for this is that the mother is insensitive to the signals of the in fact, whose brain is programmed to learn language rapidly. If these sensitive periods are neglected, the ideal time for acquiring skills passes and they might never be learned so easily again. A bird learns to sing and to fly rapidly at the right time, but the process is slow and hard once the critical stage has passed.
Experts suggest that speech stages are reached in a fixed sequence and at a constant age, but there are cases where speech tins started late in a child who eventually turns out to be of high IQ. At twelve weeks a baby smiles and makes vowel-like sounds; at twelve months he can speak simple words and understand simple commands; at eighteen months he has a vocabulary of three to fifty words. At three he knows about 1000 words which he can put into sentences, and at four he knows iris language differs from that of his parents in style. rather than grammar.
Recent evidence suggests that an infant is born with the capacity of speaking. What is special about man's brain, compared with that of the monkey, is the complex system which enables a child to connect the sight and feel of, say, a toy-bear with the sound pattern "toy-bear". And even more incredible is the young brain's ability to pick out an order in language from the mixture of sound around him, to analyze, to combine and recombine the parts of a language in new ways.
But speech has to be induced, and this depends on interaction between the mother and the child, where the mother recognizes the signals in the child's babbling, grasping and smiling, and responds to them. Insensitivity of the mother to these signals dulls the interaction because the child gets discouraged and sends out on- ly the obvious signals. Sensitivity to the child's non-verbal signals is essential to the growth and development of language.
The purpose of the Frederick Ⅱ's experiment was ______.
A．to prove that children are bom with the ability to speak
B．to discover what language a child would speak without hearing any human speech
C．to find out what role careful nursing would play in teaching a child to speak
D．to prove that a child would be damaged without learning a language

听力原文： I am honored to be here today, representing Harvard at this celebration of the College Board's half century of working to promote high standards and equal opportunity in higher education.
Before I say anything else, I want to thank everyone in the room for the work you do every day to make college affordable, available and successful for millions of young people across the country.
I want to focus my remarks on a matter of central concern to American families and to the future of the nation -- restoring education to its proper role as a pathway to equal opportunity and excellence in our society.
This has been an enduring theme in higher education, with great and creative efforts made by many institutions. Earlier this year, we announced a new initiative at Harvard aimed at the students from families of low and moderate income. Under our new program, families with incomes of less than $ 40,000 will no longer be expected to contribute to the cost of attending Harvard for their children. Families with incomes of less than $ 60,000 will also see their contributions reduced.
We are proud of this effort at Harvard, but we are aware that the programs of individual institutions with means can never be a substitute for our shared public responsibility to provide adequate funding for Pell grants and other financial aid, and for the state and community college systems that make higher education accessible and affordable for the broad public.
There is something empty about undertaking initiatives that may be right for one institution without attention to their broader impact. Likewise, we fall short if we urge changes in national policy without doing what we can on our own campuses.
In this spirit, I want to address today a problem that is emerging with increasing urgency in this nation.
