[填空题]When in August last year Britain’s security services uncovered an alleged plot to smuggle the liquid components of a bomb onto an aircraft at Heathrow, the world’s busiest international airport almost ground to a halt as additional passenger checks were ordered. It was not just flights starting from Heathrow that were delayed or cancelled, but many incoming services too. In the following days British Airways alone cut more than I 200 flights.
Intelligence to prevent attacks is part of what experts call a "layered" security approach. Other layers include checking identities, scanning people and their luggage and searching them at random. Another and increasingly important one is to see how people behave. "There are identifiers of people who have hostile intent that you can pick up," says Kip Hawley, the head of America’s Transportation Security Administration. "Our testing indicates an extraordinary high degree of success."

When Vice President Cheney spoke last year at Westminster College, its president, Fletcher Lamkin, expected a foreign policy address. Winston Churchill delivered his historic "Iron Curtain" speech there, and the school has hosted speeches by other foreign leaders.
To Lamkin’s surprise, Cheney delivered a speech against Sen. John Kerry.
Lamkin, a retired Army brigadier general(准将) and the former dean of academics at West Point, felt he had been misled. He e-mailed the college community to express his disappointment and said that in the interest of balance, he would offer Kerry a chance to speak. Very quickly his email made its way to the national media, and Lamkin found himself in the middle of a coast-to-coast quarrel. Lamkin says he was portrayed as "another college president trying to liberalize his students, and another president who is trying to poison tile minds of students and turn them into flaming liberals."
Lamkin needed
A. In New York.
B. In Chicago.
C. At Oxford University.
D. At Westminster College.

[单项选择]Last year, when President George W. Bush announced that federal funds could be used to support research on human embryonic stem cells, he mandated that only those cell lines that existed at the time would qualify for such support. More than a year later, it’s becoming increasingly :clear that these existing cell lines are inadequate. Unless more are created, the research slowdown may exact a staggering cost in terms of human suffering.
Since this announcement, the US National Institutes of Health has tried to stimulate research on .the existing cell lines with new funding and efforts to streamline the initially cumbersome process of obtaining approved cells. However, whether there are 60 cell lines, as originally stated, or nine, as now appear to be available to NIH-funded investigators, the number is not adequate. Given the genetic diversity within the population, scientists need access to new cell lines if they are to come up with the most effective cell therapies.
The is
A. is in favor of stem-cell research
B. welcomes the research slowdown
C. takes a neutral stand on the research
D. thinks it essential to Speed up the research
