[单项选择]Native Americans probably arrived from Asia in successive waves over several millennia, crossing a plain hundreds miles wide that now lies inundated by 160 feet of water released by melting glaciers. For several periods of time, the first beginning around 60,000 B.C. and the last ending around 7,000 B. C. , this land bridge was open. The first people traveled in the dusty trails of the animals they hunted. They brought with them not only their families, weapons, and tools but also a broad metaphysical understanding, sprung from dreams and visions and articulated in myth and song, which complemented their scientific and historical knowledge of the lives of animals and of people.

People from East Asia tend to have more difficulties than those from Europe in distinguishing facial expressions - and a new report published online in Current Biology explains why.
Rachael Jack, University of Glasgow researcher, said that rather than scanning evenly (均匀 的) across a face as Westerners do, Easterners fix their attention on the eyes.
"We show that Easterners and Westerners look at different face features to read facial expressions," Jack said. "Westerners look at the eyes and the mouth in equal measure, whereas Easterners favor the eyes and neglect (忽略) the mouth. "
According to Jack and her colleagues, the discovery shows that human communication of emotion is more complex than previously believed. As a result, facial expressions that had been considered universally recognizable cannot be used to reliably convey emotion in cross cultural situations.

A. The Eye as the Window to the Soul
B. Cultural Differences in Reading Emotions
C. Effective Methods to Develop Social Skills
D. How to Increase Cross-cultural Understanding
