Albert Einstein, whose theories on space time and matter helped unravel (解决) the secrets of the atom and of the universe, was chosen as "Person of the Century" by Time magazine on Sunday.
A man whose very name is synonymous (同义的) with scientific genius, Einstein has come to represent more than any other person the flowering of 20th century scientific though that set the stage for the age of technology. "The world has changed far more in the past 100 years than in any other century in history. The reason is not political or economic, but technological--technologies that flowed directly from advances in basic science," wrote theoretical physicist Stephen Hawking in a Time essay explaining Einstein’s significance. (46) .
Time chose as runner-up President Franklin Roosevelt to represent the triumph of freedom and democracy over fascism, and Mahatma Gandhi as an icon (象征) for a century when civil and human rights became crucial factors in global politics.
"What we saw was Franklin Roosevelt embodying the great theme of freedom’s fight against totalitarianism, Gandhi personifying (象征，体现)the great theme of individuals struggling for their rights, and Einstein being both a great genius and a great symbol of a scientific revolution that brought with it amazing technological advances that helped expand the growth of freedom," said Time Magazine Editor Walter Isaacson.
Einstein was born in Ulm, Germany in 1879. (47) . He was slow to learn to speak and did not do well in elementary school. He could not stomach organized learning and loathed taking exams. In 1905, however, he was to publish a theory which stands as one of the most intricate examples of human imagination in history. (48) . Everything else--mass, weight, space, even time itself--is a variable (变量) . And he offered the world his now-famous equation (公式): energy equals mass times the speed of light squared--E=mc².
(49) . "There was less faith in absolutes, not only of time and space but also of truth and morality." Einstein’s famous equation was also the seed that led to the development of atomic energy and weapons. In 1939, six years after he fled European fascism and settled at Princeton University, Einstein, an avowed pacifist, signed a letter to President Roosevelt urging the United States to develop an atomic bomb before Nazi Germany did. (50) Einstein did not work on the project. Einstein died in Princeton, New Jersey in 1955.

• A. "Indirectly, relativity paved the way for a new relativism in morality, art and politics," Isaacson wrote in an essay explaining Time’s choices.
• B. How he thought of the relativity theory influenced the general public’s view about Albert Einstein.
• C. "Clearly, no scientist better represents those advances than Albert Einstein."
• D. Roosevelt heeded the advice and formed the "Manhattan Project" that secretly developed the first atomic weapon.
• E. In his early years, Einstein did not show the promise of what he was to become.
• F. In his "Special Theory of Relativity," Einstein described how the only constant in the universe is the speed of light.

Science now might be able to explain women’s fascination with Brad Pitt’s face and George Clooney’s eyes. Women seem to (51) potential mate by how masculine (男性的) their features are, new research shows. Men with square jaws and well-defined brow ridges are seen as good short-term partners, (52) those with more feminine (女性的) traits such as a rounder face and fuller lips are perceived as better long-term mates.
In the study by Daniel Kruger at the US’s University of Michigan, 854 subjects viewed a series of (53) head shots that had been digitally changed to exaggerate or minimize masculine traits. They then (54) questions about how they expected the men in the photos to behave.
Most participants said that those with more masculine features were (55) to be risky, competitive, and more apt to fight, challenge bosses, cheat on spouses and put less effort into parenting. Those with more feminine (56) were seen as good parents and husbands, hard workers and emotionally supportive mates.
But, despite all the negative characteristics, when asked who they would choose for a short-term relationship, women selected the more masculine (57) men. Brad and George, both chiseled (轮廓清晰的) jaws and well-defined brows, then would be good for a (58) romance, not for something longer.
The study was published in the December issue of the US journal Personal Relationships.
Kruger said that from an evolutionary perspective, this (59) sense. The key is testosterone (睾丸激素) , the hormone responsible (60) the development of masculine facial features and other sexual characteristics. It has been found to affect the body’s ability to fight disease: men with high levels of the hormone are typically (61) and healthy--traits women want to pass on to their children.
However, increased testosterone has also been linked to (62) and violence in relationships. So, these men (63) produce high quality offspring, but they don’t always make great parents or faithful mates, Kruger says.
The scientific community have (64) skepticism toward physiognomy (观相术) , which links facial characteristics to certain behavioral traits. But Kruger argues that the research is a valuable tool for understanding mating strategies. And, of course, for explaining why Tony Leung and Takeshi Kanesshiro have millions of female (65) . It might have to do with their genes. Or something to do with ours.
