[单项选择]Scholars and students have always been great travelers. The official case for "academic mobility" is now often stated in impressive terms as a fundamental necessity for economic and social progress in the world, and debated in the corridors of Europe; but it is certainly nothing new. Serious students were always ready to go abroad in search of the most stimulating teachers and the most famous academies; in search of the purest philosophy, the most effective medicine, the likeliest road to gold.
Mobility of this kind meant also mobility of ideas, their transference across frontiers, and their simultaneous impact upon many groups of people. The point of learning is to share it, whether with students or with colleagues. One presumes that only eccentrics have no interest in being credited with a startling discovery, or a new technique.

The new scans showed the brain’s frontal cortex(皮层) thickening just before puberty(青春期), then slowly shrinking back to normal during the teenage years. Suddenly, the erratic huffiness(发怒) seemed to make sense: the teenage brain was a work in progress, a house in the process of being rewired.
Now comes more evidence of neural turmoil. According to psychologists in California, the speed with which youngsters can read the emotional expressions on people’s faces dips suddenly at around the age of 11 or 12 and takes years to get back on track.
The latest study, like the brain scan research before it, is a welcome and necessary p

B. positive
C. prejudiced
D. neutral
[单项选择]President Bush has once again started speaking out for comprehensive immigration reform, and a draft plan to rally Republican senators on the issue is circulating just as Congressional hearings on the issue approach. Members of Congress recognize that voters are looking for real reform that rests on resolute, effective enforcement of our immigration laws.
The only serious legislative proposal on the table offers such enforcement, because it focuses on making employers accountable for their hiring practices. To that end, the bill incorporates lessons learned from the largest immigration enforcement operation ever undertaken. Last December, Department of Homeland Security agents descended on meat processing plants run by Swirl & Company in six states, arresting more than 1,200 unauthorized workers.
The arrests were astonishing because Swift participates in Basic Pilot, a voluntary Department of Homeland Security program that allows employers to electronically verify the work el
