[简答题]Four months before election day, five men gathered in a small conference room at the Reagan-Bush headquarters and reviewed an oversize calendar that marked the remaining days of the 1984 presidential campaign. It was the last Saturday in June and at ten o’clock in the morning the rest of the office was practically deserted. Even so, the men kept the door shut and the drapes carefully drawn.

Clever genetic detective work may have found out the reason why a near-starvation diet prolongs the life of many animals.
Ronald Kahn at Harvard Medical School in Boston, U.S., and his colleagues have been able to extend the lifespan (寿命) of mice by 18 per cent by blocking the rodent’s (啮齿动物) increase of fat in specific cells. This suggests that thinness--and not necessarily diet--promotes long life in "calorie (热量卡) restricted" animals.
"It’s very cool work," says aging researcher Cynthia Kenyon of the University of California, San Francisco. "These mice eat all they want, lose weight and live longer. It’s like heaven."
Calorie restriction dramatically extends the lifespan of organisms as different as worms and rodents. Whether this works in humans is still unknown partly because few people are willing to submit to such a strict diet.

[填空题]A Microcomputer
A microcomputer is a desktop or notebook size computing device that uses a microprocessor as its Central Processing Unit, or CPU. Microcomputers are also called Personal Computers (PCs), home computers, small business computers, and micros. The smallest, most compact are called laptops. When they first appeared, they were considered single user devices, and they were capable of handling only four, eight, or 16 bits of information at one time. More recently the distinction between microcomputers and large, mainframe computers (as well as the smaller mainframe type systems called minicomputers) has become blurred, as newer microcomputer models have increased the speed and data handling capabilities of their CPUs into the 256 bit. or even much more bit multi-user range.
