　　The days of elderly women doing nothing but cooking huge meals on holidays are gone. Enter the Red Hat Society--a group holding the belief that old ladies should have fun.
"My grandmothers didn't do anything but keep house and serve everybody. They were programmed to do that," said Emily Cornette, head of a chapter of the 7-year-old Red Hat Society.
　　While men have long spent their time fishing and playing golf, women have sometimes seemed to become unnoticed as they age. But the generation now turning 50 is the baby boomers( 生育高峰期出生的人) , and the same people who refused their parents' way of being young are now trying a new way of growing old.
　　If you take into consideration feminism( 女权主义), a bit of spare money, and better health for most elderly, the Red Hat Society looks almost inevitable (必然的). In this society, women over 50wear red hats and purple(紫色的) clothes, while the women under 50 wear pink hats and light purple clothing.
　　"The organization took the idea from a poem by Jenny Joseph that begins: When I am an old woman, I shall wear purple. With a red hat which doesn't go," said Ellen Cooper, who founded the Red Hat Society in 1998. When the ladies started to wear the red hats, they attracted lots of attention."The point of this is that we need a rest from always doing 　　something for someone else," Cooper said, "Women feel so ashamed and sorry when they do something for themselves. " This is why chapters are discouraged from raising money or doing anything useful. "We're a ladies' play group .It couldn't be more simple," added Cooper's assistant Joe Heywood.

The underlined word "chapter" in Paragraph 2 means

A．one branch of an organization
B．a written agreement of a club
C．one part of a collection of poems
D．a period in a society's history

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. The researchers studied cultural differences in the recognition of facial expressions by recording the eye movements of 13 Western Caucasian and 13 East Asian people while they observed pictures of expressive faces and put them into categories: happy, sad, surprised, fearful, disgusted, angry, or neutral,They compared how accurately participants read those facial expressions using their particular eye movement strategies.
It turned out that Easterners focused much greater attention on the eyes and made significantly more errors than did Westerners. "The cultural difference in eye movements that they show is probably a reflection of cultural difference in facial expressions," Jack said." Our data suggest that whereas Westerners use the whole face to convey emotion, Easterners use the eyes more and mouthless. "
In short, the data show that facial expressions are not universal signals of human emotion. From here on, examining how cultural factors have persified these basic social skills will help our under-standing of human emotion. Otherwise, when it comes to communicating emotions across cultures ,Easterners and Westerners will find themselves lost in translation.

The discovery shows that Westerners

A．pay equal attention to eyes and mouth
B．consider facial expressions universally reliable
C．observe eyes and mouth in different ways
D．have more difficulties in recognizing facial expressions
