Let a student take you and your family，school，or organization on an engaging，hour-long free historical tour of the Harvard campus．The tours leave from the Events & Information Center. Not only will you discover the location of fascinating exhibitions and programmes on campus，you will also see Harvard’s rich sampling of American history and architecture from the Colonial period to the present.
Schedule of Tours
Tours leave the Events ＆ Information Center at 10 am and 2 pm Monday through Friday, and at 2 pm on Saturday through the academic year（February 4 through May 2；September 23 through December 16）. Summer tours（June 24 through August 15）are offered at 10 am，11:15 am，2 pm，and 3：15 pm Monday through Saturday．Reservations for special tours of 20 or more people may be made by calling the Events & Information Center at（617）495—1573 or emailing icenter@camail. Harvard. edu. Tours are stopped March 23 through April 2 for Spring break，May 3 through June 23 for Spring intercession（祷告）, and August 16 through September 22 for Summer intercession．

Rising levels of carbon dioxide in the atmosphere are a major cause of climate change, and now a new study has confirmed that atmospheric CO2 is also affecting the ocean chemistry and potentially harming sea life.
Montana State University scientist Robert Dore has been researching the water in the Pacific Ocean for almost two decades.
"We've been going to the same spot in the Pacific Ocean, and we try and characterize long-term change in the open ocean environment. And one of the key things that we measure is CO2 levels. And we've been able to record this increasing quantity of atmospheric CO2 into the ocean."
Scientists expected that as atmospheric CO2 increased, more and more of the carbon dioxide would be absorbed into the ocean, affecting the chemical balance of the sea water, with a potentially harmful impact on shellfish and coral in particular.
"As carbon dioxide dissolves（溶解） in the water, or seawater in this case, it forms a weak acid, carbonic acid," Dore explains. "And therefore, as the concentration of CO2 in the atmosphere goes up and that exchanges with the surface seawater, it drives the pH down, and makes it more acidic."
The seawater Dore and his colleagues have analyzed confirms what the theory predicts.
The effect was particular striking at about 250 meters down, and again at 500 meters. Dore and his colleagues came up with two possible explanations. It could be that surface water picked up CO2 and then moved to those depths. Or there could be a biological explanation.
"It's important to realize that the oceans are really becoming acidic. And it can have negative impacts on a whole variety of sea life from fish to coral. It's potentially catastrophic."
1.What can be the best title of the passage?
A．Sea Life Facing Danger B．Climate Change Affecting Seawater
C．Oceans Becoming More Acidic D．Scientist Researching Seawater
2.Which of the following shows the process of the impact of atmospheric CO2 on sea life?
a．Sea life is endangered．
b．CO2 goes into the surface water．
c．The ocean chemistry is affected．
d．CO2decreases the PH and makes the seawater more acidic．
e．CO2 levels in the atmosphere go up．
A. a → b → c → d → e
B. e → b --→ c → d → a
C. a → e -→ b → c → d
D. e → d -→ c → b → a
3.Scientist Robert Dore came to the conclusion based on .
A．his research and analysis
B．a major cause of climate change
C．some former theory
D．the expectation of other scientists
4.What does the passage want to tell us most?
A．It takes time to make a scientific study．
B．Atmospheric CO2 is doing harm to sea life．
C．Robert Dore is a committed and serious scientist．
D．Measures should be taken to prevent the potential catastrophe．
People with less education suffer fewer stressful days, according to a report in the current issue of the Journal of Health and Social Behavior.
However, the study also found that when less-educated people did suffer stress it was more severe and had a stronger effect on their health.
From this, researchers have concluded that the day-to-day factors that cause stress are regular. Where you are in society determines the kinds of problems that you have each day, and how well you will cope with them.
The research team interviewed a national sample of 1, 031 adults daily for eight days about their stress level and health. People without a high school diploma reported stress on 30 percent of the study days, people with a high school degree reported stress 38 percent of the time, and people with college degrees reported stress 44 percent of the time.
“Less advantaged people are less healthy on a daily basis and are more likely to have downward turns in their health.” leading researcher, Dr. Joseph Grzywacz of Wake Forest University Baptist Medical Center, said in a prepared statement. “The downward turns in health were connected with daily stressors (紧张刺激物), and the effect of daily stressors on their health is much more damaging for the less advantaged. ”
“If something happens every day, maybe it’s not seen as a stressor.” Grzywacz says. “Maybe it is just life.”
1.Stress level is closely related to ___ .
A. family size B. work experience
C. body weight D. social position
2.Which group reported the biggest number of stressful days?
A. People without any education. B. People without high school degrees.
C. People with high school degrees. D. People with college degrees.
3.The less advantaged people are, the greater .
A. the effect of stress on their health is B. the degree of their health concern is
C. the level of their education is D. the effect of education on their health is
4.Less-educated people report fewer days of stress possibly because .
A. they don’t want to tell truth B. they don’t want to face the truth
C. stress is too common a factor in their life D. their stress is much greater
