because his body was cremated (焚化), there was no chance to test for the virus.

[单项选择]Passage 5
Bird wings have a much more complex job to do than wings of an airplane, for in addition to supporting the bird they must act as its engine, rowing it through the air. Even so the wing outline of a bird conforms to the same aerodynamic principles as those eventually discovered by people when designing airplanes, and if you know how different kind of aircraft perform, you can predict the flight capabilities of similarly shaped birds.
Short, stubby wings enable a tanager and other forest-living to swerve and dodge at speed through the undergrowth, just as they helped the fighter planes of the Second Word War to make tight turns and acrobatic maneuvers in a dog-fight. More modern fighters achieve greater speeds by sweeping back their wings while in flight, just as peregrines do when they go into a 130 kph dive, swooping to a kill. Championship gliders have long, thin wings so that, having gained height in a thermal up-current they can soar gently down for hours
A. Bird wings have to support the bird.
B. Bird wings must act as the bird’s engine.
C. Airplane’s wings must act as the airplane’s engine.
D. Similar wing shapes in aircraft and birds produce similar flight capabilities.

BRITAIN’S universities are in an awful
spin. Top universities were overwhelmed by the 24% of A-level applicants with

government. Ministers want to see half of all young people in universities by
2010 (numbers have stalled at 42%), without letting go of the world-class
quality of its top institutions.
Many argue that the two goals
are incompatible without spending a lot more money. Re searchers scrabble for
funds, and students complain of large classes and reduced teaching time. To help
solve the problem, the government agreed in 2
A. A．Top universities offer fewer places than before.
B．Many students are attracted by the incentives.
C．Most universities have to cut the tuition fees.
