[简答题] The most obvious difference between real essays and the things one has to write in school is that real essays are not exclusively about English literature. Certainly schools should teach students how to write. But due to a series of historical accidents the teaching of writing has gotten mixed together with the study of literature. And so all over the country students are writing not about how a baseball team with a small budget might compete with the Yankees, or the role of color in fashion, or what constitutes a good dessert, but about symbolism in Dickens.
How did things get this way To answer that we have to go back almost a thousand years. Around 1100, Europe at last began to catch its breath after centuries of chaos, and once they had the luxury of curiosity they rediscovered what we call "the classics." The effect was rather as if we were visited by beings from another solar system. These earlier civilizations were so much more sophisticated that for the next several c

[填空题]Last year’s economy should have won the Oscar for best picture. Growth in gross domestic product was 4.1 percent; profits soared; exports flourished; and inflation stayed around 3 percent for the third year.
41.________________________________. Jobs insecurity was rampant. Even as they announced higher sales and profits, corporations acted as if they were in a tailspin, cutting 516, 069 jobs in 2003 alone, almost as many as in the recession year of 1991. Yes, unemployment went down.
But over one million workers were so discouraged they left the labor force. More than 6 million who wanted full-time work were only partially employed; and another large group was either overqualified or sheltered behind the euphemism of self-employment. We lost a million good manufacturing jobs between 1998 and 2002, continuing the trend that has reduced the blue-collar work force from about 30 percent in the 1950s to about half of that today. 42.________________________________.

[单项选择]Given the briefest of glances at a picture, most people believe they have not had time to recognize anything in it at all. Ask them whether they saw an animal and they consider themselves to be making a futile guess. Yet those guesses are right much more often than they are wrong. That is because the brain can carry out immediate visual processing even when it does not have time for any cognitive back-chatter. A neuroscientist trying to understand how people recognize objects would thus start with this simplest of systems.
That is the purpose of Dr. Serre’s computer. His project is nothing less than ad attempt to reverseengineer the relevant part of the brain. That part is the ventral visual pathway. Anatomy shows that it is organized into numerous areas. Experiments on monkeys, in which researchers have recorded what excites individual nerve cells in each of these areas, give strong hints about how it works.
The pathway is hierarchical. Signals from the retina flow to the mo
