必修第一册　Unit 3　Sports and Fitness Ⅰ.阅读理解 Want to learn a new language or get A’s in college exams Previous studies have shown that exercise can help stimulate the areas of the brain that convert(转换) new information into long-term memory.A new study has taken this information one step further and found the best time when exercise can help maximise learning. Building upon past research that found exercise releases biochemicals that improve mental function，scientists at Radboud University and the University of Edinburgh conducted a study to determine when exercise was most beneficial to learning. Participants—72 healthy male and female adults—were first asked to perform a computer test that challenged their visual and spatial learning.After the test，all of the subjects watched nature documentaries，but two-thirds of them also exercised.Half of the exercisers did circuit training on an exercise bike for 35 minutes immediately after the test.The other half did the same exercise but not until four hours after they had been tested. Two days later，all of the participants returned to the lab for a recall test，and they were connected to MRI(磁共振成像) machines to assess their brain activity.The participants who exercised four hours after taking the computer test were able to recall what they had learned most accurately.Their brainwaves also showed more consistent levels of activity，indicating that their brains were less taxed to remember what they had learned. According to this research，the best time to exercise to improve learning is four hours after studying.But why That’s one question the researchers have yet to answer.Another question left unanswered is the level of exercise that might best improve learning.I’ve run enough marathons to prove the fact that my brain is anything but sharp during or after a tough workout.But the researchers noted that light workouts might not give the brain enough of a biochemical boost to improve learning. (　　)1.What did the new study aim to explore A.When exercise is best for learning. B.What biochemicals are good for health. C.How brainwaves should be measured. D.Which area of the brain is the most active. (　　)2.What were all the participants asked to do during the experiment A.Train on bicycles. B.Do mathematics exercises. C.Play computer games.

D.To finish their previous tasks. (　　)4.What might the author’s marathon running prove A.The findings of the study are reliable. B.Long-distance runners are often smart.
