| Tests conducted at the University of
Pennsylvania’s Psychological Laboratory showed that anger is one of the most
difficult emotions to detect from facial expression. Professor Dallas E. Buzby
confronted 716 students with pictures of extremely angry persons, and asked them
to identify the emotion from facial expression. Only 2 percent made correct
judgments. Anger was most frequently judged as "pleased." And a typical reaction
of a student with the picture of a man who was hopping mad was to classify his
expression as either "bewildered", "quizzical", or simply "amazed". Other
students showed that it is extremely difficult to tell whether a man is angry or
not just by looking at his face. The investigators found further that women are
better at detecting anger from facial expression than men are. Paradoxically,
they found that psychol A. is difficult to detect by looking at a person’s face B. is frequently confused with other emotions C. is detected by women better than by men D. cannot be detected by a psychologically trained person [填空题]
A growing list of established colleges and universities are extending access to their courses to students all over the world via the Net, creating a new type of education facility called "virtual(虚拟)universities". These days you can get degrees, masters, MBAs, BAs and Doctorates from all over the world through Internet courses. Colleges and Universities in the U. S. A. , Asia, Europe, U. K. , Australia and many other places are racing to set up virtual study centers in the hope of attracting students.

[单项选择] From the beginning, the idea of a finite universe ran into its own obstacle, the apparent need for an edge, a problem that has only recently been grappled with. Aristotle’’s argument, that the universe is finite, and that a boundary was necessary to fix an absolute reference frame, held only until scientists wondered what happened at the far side of the edge. In other words, why do we not redefine the "universe" to include that other side
Riemann ingeniously replied by proposing the hypersphere, the three- dimensional surface of a four-dimensional ball. Previously it was supposed that the ultimate physical reality must be a Euclidean space of some dimension, and thus if space were a hypersphere, it would need to sit in a four-dimensional Euclidean space that allows us to view it from the outside. But according to Riemann, it would be perfectly acceptable for the universe to be a hypersphere and not embedded in any higher-dimensional space; nature need not therefore cling to the a
A. Of the three models of spatial curvature proposed by Einstein, only spherical geometry contradicts the Euclidean model. B. The primary evidence for the notion is that that observers cannot see spatial flexure directly, but perceive it as gravitational attraction. C. Space mapped on the spherical geometrical model may curve in one of three ways, as Einstein proposed. D. Spheres typically contain only three dimensions, whereas most models of the universe attribute it at least four. E. Scientists are skeptical, given that mass and energy quantities seem insufficient, yet ultimately do not know enough to dismiss the notion. 我来回答: 提交
