[单项选择]In the next century we’ll be able to alter our DNA radically, encoding our visions and vanities while concocting new life-forms. When Dr. Frankenstein made his monster, he wrestled with the moral issue of whether he should allow it to reproduce, "Had I the right, for my own benefit, to inflict the curse upon everlasting generations" Will such questions require us to develop new moral philosophies
Probably not. Instead, we’ll reach again for a time-tested moral concept, one sometimes called the Golden Rule and which Kant, the millennium’s most prudent moralist, conjured up into a categorical imperative: Do unto others as you would have them do unto you; treat each person as an individual rather than as a means to some end.
Under this moral precept we should recoil at human cloning, because it inevitably entails using humans as means to other humans’ ends and valuing them as copies of others we loved or as collections of body parts, not as individuals in their own right. We sho

Scientists can determine someone’ s favorite food from their body shape. They have discovered that the arrangement of taste buds(舌部味蕾) on the tongue varies for different body types. The scientist team examined 1,000 British adults and divided them into three physiologically recognized body types-ectomorphs, endomorphs and mesomorphs. They determined that a person’ s body type indicated where they were likely to have the most taste buds on the sweet, bitter or salty areas of their tongue.
The study showed that ectomorphs, who make up one in three of the population, usually have a small delicate shape, have a sweet tooth but hate bitter foods. Mesomorphs, who make up 20 percent of the population, usually have a muscular shape and prefer salty or bitter foods but dislike sweet foods. Half the British population are endomorphy with soft, rounded bodies, and they like most foods. The findings showed that for two in three people food preference was a physiological r
