31.What is a suitable title for the text?A.Amboseli Succeeds in Preserving Iconic Wildlife SpeciesB.Local Communities Make Great Contributions to Wildlife ProtectionC.Leturesh's Model Sets a Good Example for VillagersD.Kenyan Conservationist Wins Award for Wildlife ProtectionDScientists of the University of Antwerp and University of Liege have found how thehuman brain changes and adapts to weightlessness,after being in space for 6 months.A child who learns not to drop a glass on the floor is an example of how the brainfollows the physical laws of gravity to best function on Earth.Astronauts who go to spacestation live in a weightless environment,where the brain's rules about gravity are nolonger applicable.A new study on brain function in astronauts has found how the brain'sorganization is changed after a six-month mission to the International Space Station(ISS).The University of Antwerp has been leading this BRAIN-DTI scientific projectthrough the European Space Agency.Magnetic resonance imaging(MR)(磁共振成像)data were taken from 14 astronauts'brains before and several times after their mission tospace.Using a special MRI technique,the researchers collected the astronauts'braindata in a resting condition.In cooperation with the University of Liege,recent analyses of the brain's activity atrest found how functional connectivity,a marker of how activity in some brain areas isconnected with the activity in others,changes in specific regions."We found thatconnectivity was altered after spaceflight in regions which support the combination ofdifferent types of information,rather than dealing with only one type each time,"saySteven Jillings and Floris Wuyts."Moreover,we found that some of these changedcommunication patterns remained throughout 8 months of being back on Earth.At thesame time,some brain changes returned to the level of how the areas were functioningbefore the space mission."The researchers are excited with the results,though they know it is only the firststep in pursuing our understanding of brain communication changes after space travel.For example,we need to understand whether longer time spent in outer space mightinfluence these observations,and whether brain characteristics may be helpful inselecting future astronauts or monitoring them during and after space travel.高二英试·第7页（共12页）
