3 "Exploitation of this vulnerability could have affected the glue that holds the Internet together," said Roger Cumming, director for England’s National Infrastructure Security Coordination Centre.

[单项选择]It was not until modern scholarship uncovered the secret of reading Middle English that we could understand that Chaucer, far from being a rude versifier, was a perfectly accomplished technician, and that his verse is rich in music and elegant to the highest degree. Chaucer’s own urbane personality is a delight to encounter in his books, He is avowedly a bookworm, yet few poets observe nature with more freshness and delight. He is a master of genial satire but can sympathize with true piety and goodness with as much pleasure as he attacks the hypocritical.

But the probe into whether the FBI mishandled information about Major Nidal Malik Hasan, who is charged with killing 13 people and wounding 32 at Fort Hood in Texas, could be Webster’s trickiest assignment yet. The Nov. 5 shootings have raised a host of nettlesome issues regarding Hasan and his contacts with Anwar al-Awlaki, a radical cleric in Yemen, and why the FBI decided not to raise the alarm about Hasan even though it had tracked his suspect communications. In the aftermath of the shootings, critics have raised questions not only about intelligence-sharing, but also ab
