New findings suggest that brainy card games such as contract bridge may temporarily(臨時地) 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(神經免疫學), whose name reflects the fact that the nervous system and the immune system are not considered separate and isolated(獨立的) 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.
【小題1】Playing bridge can help one to fight off diseases because it can _______.

A.raise production of a key blood cell B.make people joyful
C.aid digestionD.make break away from the bad habits
【小題2】Diamond chose to study bridge players for the research because _______.
A.the players are good friends of hers
B.she loves playing bridge
C.this game stimulates a part of the brain that has something to do with immune system
D.she is a clever manager, who operates her bridge club well
【小題3】A T cell is _______ cell.
A.a brainB.a white blood
C.a red blood D.a kind of dangerous blood
【小題4】Which of the following is true according to this article?
A.The immune system and the brain system used to be considered separate and isolated systems.
B.The help to the immune system that is brought about by playing bridge can last for a long time.
C.Cortex is a kind of blood cell.
D.The new findings are impossible.

While reading a story on 20-somethings complaining about how the economy was ruiningg their life plans, I couldn’t help but think the 20-somethings sounded like a bunch of spoiled who grew up expecting everything to be easy for them. As a 20-something myself, certainly share their disappointment : my husband and I probably won’t be able to buy a house until we’re in our 40s, and we two are burdened by student loans(貸款). But why should it be any different? Being young persons in America, shouldn’t they take up all of the challenges and opportunities that this country offers?
Consider some of these views shared in the story: Jennifer, 29, owner of a two-bedroom apartment with her husband, worries that she won’t be able to have children for at least a decade because they can’t afford to buy a house yet.
I read that, and I thought what planet she is living on where you need to own a house in order to have kids? Has she ever visited a developing country, or even downtown areas in this one? Home ownership is a luxury(奢華), not a fertility requirement.
A 26-year-old in the story is disappointed that he can’t afford to get a Ph. D in literature. Well, that sounds a bit like expressing disappointment that no one will pay you to write poetry on the beach in Thailand for five years.
Yes, it’s sad that these young people feel so lost. But I think the problem is their extremely high expectations, not economic reality. Beth Kobliner, author of Personal Finance in Your Twenties and Thirties, says that she thinks people’s expectations grew up at a time when everyone’s wealth appeared to be increasing, Their parents probably saw their home values rise along with their investments. “So you have people who have grown up in an environment where people had great expectations of what living well means,” says Kobliner.
This recession(經濟衰退) will certainly play a role in forcing those expectations into more realistic group. In the meantime, it seems a lot better for our mental health to focus on being grateful---for our one-bedroom apartments, for living in modern cities, or perhaps just for being able to eat three meals a day---than on longing for some kind of luxury life.
【小題1】. What makes the author think the 20-somethings sound like a bunch of spoiled children?

A.They expect everything to be easy for them.
B.They complain that the economy is spoiling their life plans.
C.They are unwilling to face all of the challenges.
D.They are burdened by student loans.
【小題2】. The underlined word “fertility” in paragraph 3 probably means“_____”.
A.baby productionB.pleasantC.baby comfortD.comfortable
【小題3】. Which of the following is NOT mentioned about the complaints of the 20-somethings?
A.They can’t have children for at least a decade a decade to buy a house.
B.They have only a one-bedroom apartment to live in.
C.They can’t buy a house until 40 and are burdened by student loans.
D.They despair at not being able to afford a PH. D in literature.
【小題4】. What’s the Kobliner’s attitude towards the 20-somethings with high expectations?
A.UnbearableB.OppositeC.DoubtfulD.Understanding
【小題5】What is the best title for this passage?
A.Young people afford to continue their study
B.Young people can’t afford to buy a house
C.Young people’s high hopes create despair
D.The 20-somethings’ high expectations

A new study says that birds living in big cities sing shorter, faster songs that are higher-pitched (高音調的) than those sung by their brothers in the forests. The researchers think that the birds adjust their songs to allow themselves to be heard over the noises of the city, especially the low traffic noise.
To study how urban birds song, Hans Slabbekoorn and Ardie den Bore, biologists at the University of Leiden in Netherlands, travelled around Europe and recorded bird songs in ten major cities and in nearby forests. The species they focused on, the great tit (大山雀), is widespread across Eurasia and one of the few types of birds that thrives in big cities.
Singing is crucial (重要的) for males, which use their songs to attract mates and mark out their territory. The changing songs could play a role in eventually causing the city birds and the forest dwellers to evolve into separate species.
The findings could also help explain why usually only a few bird species thrive in cities. By contrast, many more bird species tend to be found in forests and other undeveloped habitats.
Studies like this could eventually help researchers predict how urbanization (都市化) will affect birds, using this knowledge could help urban planners design more pleasant city environments, study co-author Slabbe-koorn said. “You can make a city much more livable if you pay attention to where the noise goes and where the people go,” he said. “It would be easy to fit the birds into those models.” Then cities wouldn’t be strictly for the people, but also for the birds.
【小題1】 Which is the best title of the passage?

A.Birds Change Songs to Suit Country Life
B.Birds Change Sex to Suit Urban Life
C.Birds Change Living Habits to Suit Urban Life
D.Birds Change Songs to Suit Urban Life
【小題2】 Males usually sing their songs to ____.
A.evolve into another species
B.attract mates and mark out their living area
C.attract city people’s attention and make them supply food
D.allow themselves to be heard over the noises of the city
【小題3】 The underlined word “thrives” in the second paragraph means “____”.
A.diesB.survivesC.suffers D.travels
【小題4】What is NOT the effect that studies of birds’ songs have?
A. Predicting how course of the city’s expanding will affect birds.
B. Helping the city planners design more pleasant city environments.
C. Making cities more livable for both the birds and people.
D. Driving the urban birds back to the forest.
