New findings suggest that brainy card games such as contract bridge may temporarily(临时地) raise production of a key blood cell including in fighting off illness. After 90 minutes of play, bridge players had increased levels of immune(免疫) cells, according to the research reported last week.
A researcher, Diamond, studied bridge players from a women’s bridge club. She chose bridge players because the game includes skills stimulating(刺激) a part of the brain called the dorsolateral cortex. Earlier animal research suggests that this part of the brain may play a role in the immune system.
The findings are based on blood samples drawn from 12 women players. Their blood samples showed a rise in levels of white blood cells called T cells after they played bridge for 90 minutes. T cells are produced by the thymus gland(胸腺) and used by the immune system against diseases.
The T cell count jumped significantly in eight of the bridge players, and slightly in the other four. The findings contribute to the field of neuroimmunology(神经免疫学), whose name reflects the fact that the nervous system and the immune system are not considered separate and isolated(独立的) systems. What isn’t clear is whether the help to the immune system from an activity like contract bridge is lasting or temporary. It is also not clear whether the increase in T cells could finally be targeted against special illnesses.

D.The new findings are impossible. |
I have been using the Internet since I was five years old, when my dad first sat me down in front of a computer and connected me the World Wide Web.
I’ve always felt like a master of the Internet world. AOL Instant Messaging, MSN, Gmail, Facebook, Myspace -- I’ve got it all under control. I thought there was nothing more to it besides checking my e-mail and wasting my time, until I was introduced to electronic commerce(e-commerce): business on the Internet.
Some online businesses are run from one-room home offices. Others have hundreds of employees (雇员) across the world. Have you ever heard of Amazon.com, Yahoo.com?
My friends often said they got cheap textbooks off Amazon.com, or had a good deal (交易) on Steve Madden shoes that were on sale at SteveMaden.com. Unfortunately for me, I continued my “e-commerceless” Web-surfing, not knowing about all the deals I was missing out on.
That is, of course, until my sister finally sold the idea to me.
“Why are all these packages arriving in the mail for you, Katy?” I asked her one day. Strange envelopes (信封) had been put on our doorstep for weeks now, each one always addressed to my sister; and we all know little sisters should never be getting more mail than their elders!
“Oh, it’s the things I ordered online!” she answered. I watched speechlessly as she opened them. There was no way our parents were letting her spend that much money- online or off!
“How much did all of this coat?”
“Oh, only about $15 in all!” She said excitedly. “Everything on eBay is on sale! It’s a way better than going to the mall.”
I felt as if there had been a store right in my backyard that I had never walked into! That week, I ordered a used Spanish textbook for my summer course online for 10 percent of the publishing price. A few days later, I bought an iPod protector and a book or two via the wonderful eBay.com.
【小题1】From the first two paragraph we can conclude that the author
A.had no experience using computers |
B.had no idea of what e-commerce is |
C.only used the Internet to check e-mail |
D.thought surfing the Internet was a waste of time |
A.he stopped web-surfing |
B.he visited a store in his backyard |
C.his sister explained the packages she got by mail |
D.his friends told him about the online deals they made |
A.never enjoyed shopping that much |
B.loves the big store in her backyard |
C.feels she is a true master of the Internet |
D.has begun to enjoy online shopping |
A.To tell the readers how he begins online shopping. |
B.To do business on the Internet. |
C.To make an online shopping ad. |
D.To advise people not to do online shopping |
Rae Armantrout, who has been a poetry professor at the University of California San Diego(UCSD) for two decades, has won the 2010 Pulitzer Prize in the poetry category for her most recent book, “Versed”.
“I’m delighted and amazed at how much media recognition that the Pulitzer brings, as compared to even the National Book Critics Award, which I was also surprised and delighted to win,” said Armantrout.
“For a long time, my writing has been just below the media radar, and to have this kind of attention, suddenly, with my 10th book, is really surprising.”
Armantrout, a native Californian, received her bachelor’s degree at UC Berkeley, where she studied with noted poet Denise Levertov, and her master’s in creative writing from San Francisco State University. She is a founding member of Language Poets, a group in American poetry that analyzes the way language is used and raises questions to make the reader think.
In March, she won the National Book Critics Circle Award for “Versed.”
“This book has gotten more attention,” Armantrout said, “but I don’t feel as if it’s better.”
The first half of “Versed” focuses on the dark forces taking hold of the United States as it fought the war against Iraq. The second half looks at the dark forces casting a shadow over her own life after Armantrout was diagnosed with cancer in 2006.
Armantrout was shocked to learn she had won the Pulitzer but many of her colleagues were not. “Rae Armantrout is a unique voice in American poetry,” said Seth Lerer, head of Arts and Humanities at UCSD.
“Versed”, published by the Wesleyan University Press, did appear in a larger printing than her earlier works, which is about 2,700 copies. The new edition is scheduled to appear in May.

When the research on the effect of electric fields on E.coli was begun in 1962, it was essential that a biologist–specifically, a microbiologist–contributed to the project.She does not want her name used because she did not become a scientific researcher for fame, but rather for the challenge of putting pieces of a scientific puzzle together.As a girl, she was inspired by the work of great scientists: she read the story of the cure of malaria in the Panama Canal; she also read a biography of Madame Curie.These accounts inspired her to pursue a career in scientific research.After high school, she worked for the Michigan Department of Health, where she did research in biology and microbiology.There, her colleagues saw her talent and encouraged her to pursue science as a career.She went on to earn a bachelor’s degree from Michigan State University in 1948 in medical technology.
When she began working at Michigan State in the early 1960s,
she was balancing the demands of scientific research with the needs
of her family.At that time both of her children were in school.She
would work in the lab in the morning while they were at school,
go home to see them at lunch, return to the lab for the afternoon, go
home for dinner, and return to the lab in the evening, if necessary.
At that time, there were fewer women scientists working than
there are today, but she encountered several in her career.At the
Michigan Department of Health, many of her colleagues were women and, consequently, she did not feel isolated because of her gender–nor did she feel that she was treated differently because she was a woman.
While working at Michigan State, she also felt that she was treated with respect by her peers.Her colleagues, among them doctors and Ph.D.chemists, all treated her as an equal.On the whole, she believes that there is not a great deal of difference between men and women in science.
56.Why does the woman scientist refuse to let out her name?
A.Because she is a shy lady.
B.Because she doesn’t mind her fame.
C.Because she never takes pride in her research.
D.Because she never works for her fame.
57.What is the noble lady scientist really interested in?
A.The life stories of other women scientists.
B.Biology and microbiology.
C.The secret of the success of the other scientists.
D.The difference between men and women scientists.
58.Who helped and encouraged her to carry on her scientific research?
A.Her family and friends. B.Madame Curie.
C.Her colleagues and other scientists. D.Some of the officials.
59.What is the whole passage mainly about?
A.The life story of a famous woman scientist with great success.
B.A brief introduction about an unknown great woman scientist.
C.The new development of a special woman scientist.
D.The secret of an infamous woman scientist.
Dear editor,
Mary is my friend and she is a very good-hearted girl. She’s always the first to help out others. But her habits make me mad sometimes and she just won’t change her ways. For most situations, that’s just fine with me, as I know it’s what make her who she is. However, sometimes it’s just so hard for me to bear her behavior. She has recently got a cellphone, but she often borrows mine to make calls. My phone has a chain with it. She always tries to open it like her own phone. I usually open it for her, but not always, as sometimes I’m driving my car, so she needs to get it out of my purse and open it herself.
This weekend we were at a party in a faraway village. She borrowed my cellphone. As it was cold outside, I let her take it outside without opening it. Now it’s broken because she didn’t open it properly. I wouldn’t be so mad, but over the weekend she also borrowed my car and never offered to pay for the gas, which made me very angry. She should have offered to pay for the gas. As I have mentioned, she’s the type to help out others when and where she can. Perhaps because of that, she thinks others should also do the same for her. Sometimes I just think she is very childish. I don’t want to hurt her, but I do want to let her know that not everyone can accept that. What should I do to let her know that?
Yours,
Lily
