A new research has discovered that meditation(冥想)and oxygen sport together reduce depression(抑郁). The Rutgers University study found that this mind and body combination, done twice a week for only two months, reduced the symptoms of a group of students by 40 percent.

“We are excited by the findings because we saw such a meaningful improvement in both clinically depressed and non-depressed students, ”said lead author Dr. Brandon Alderman.“It is the first time that both of these two behavioral ways have been looked at together for dealing with depression.”

Researchers believe the two activities have an interactive(交互的)effect in combating depression. Alderman and Dr. Tracey Shors discovered that a combination of mental and physical training( MAP) enabled students with major depressive disorder not to let problems or negative thoughts defeat them.

Rutgers researchers say those who participated in the study began with 30 minutes of focused attention meditation followed by 30 minutes of oxygen sport. They were told that if their thoughts drifted to the past or the future they should refocus on their breathing, which enabled those with depression to accept moment-to-moment changes in attention.

Shors, who studies the production of new brain cells in the hippocampus-part of the brain involved in memory and learning-says scientists have shown in animal models that oxygen sport exercise keeps a large number of certain cells alive.

The idea for the human intervention(干预)came from her laboratory studies, she says, with the main goal of helping individuals acquire new skills so that they can learn to recover from stressful life events.

By learning to focus their attention and exercise, people who are fighting depression can acquire new learning skills that can help them process information and reduce the overwhelming recollection of memories from the past, Shors says.

“We know these treatments can be practiced over a lifetime and that they will be affective in improving mental health, ”said Alderman.“The good news is that this intervention can be practiced by anyone at any time and at no cost.”

【小题1】What made the research so different?
A.Adopting a way of meaningful talk.B.Treating depression with special medicine.
C.Combining the two ways to reduce depression.D.Comparing the depressed with the non-depressed.
【小题2】The underlined word "combasting" in Paragraph 3 probably means __________.
A.fightingB.developingC.improvingD.examining
【小题3】What can we know about what the participants did in the research?
A.They did oxygen sport half an hour before thinking.B.They thought quietly and then took exercise.
C.They took exercise longer than they thought.D.They took exercise while thinking quietly.
【小题4】What is Shors' main purpose of her studies?
A.To find out certain brain cells of humans.B.To study the production of new brain cells.
C.To offer people a new method to reduce stress.D.To decide the links between stress and exercise.
