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 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 maximize 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 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.
题目：
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. Watch films about nature.
3. Why did the participants return to the lab two days later?
A. To do a medical examination.
B. To have their memory tested.
C. To get their workouts recorded.
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.
C. Studies on the marathon are not enough.
D. Hard exercise may not sharpen the brain.

As we age, even if we're healthy, the heart just isn't as efficient in processing oxygen as it used to be. In most people the first signs show up in their 50s or early 60s. And among people who don't exercise, the changes can start even sooner. "Think of a rubber band. In the beginning, it is flexible, but put it in a drawer for 20 years and it will become dry and easily broken," says Dr. Ben Levine, a heart specialist at the University of Texas. That's what happens to the heart. Fortunately for those in midlife, Levine is finding that even if you haven't been an enthusiastic exerciser, getting in shape now may help improve your aging heart. Levine and his research team selected volunteers aged between 45 and 64 who did not exercise much but were otherwise healthy. Participants were randomly divided into two groups. The first group participated in a program of nonaerobic exercise—balance training and weight training—three times a week. The second group did high-intensity aerobic exercise under the guidance of a trainer for four or more days a week. After two years, the second group saw remarkable improvements in heart health. "We took these 50-year-old hearts and turned the clock back to 30-or 35-year-old hearts," says Levine. "And the reason they got so much stronger and fitter was that their hearts could now fill a lot better and pump a lot more blood during exercise." But the hearts of those who participated in less intense exercise didn't change, he says. "The sweet spot in life to start exercising, if you haven't already, is in late middle age when the heart still has flexibility," Levine says. "We put healthy 70-year-olds through a yearlong exercise training program, and nothing happened to them at all." Dr. Nieca Goldberg, a spokeswoman for the American Heart Association, says Levine's findings are a great start. But the study was small and needs to be repeated with far larger groups of people to determine exactly which aspects of an exercise routine make the biggest difference.
题目：
1. What does Levine want to explain by mentioning the rubber band?
A. The right way of exercising.
B. The causes of a heart attack.
C. The difficulty of keeping fit.
D. The aging process of the heart.
2. In which aspect were the two groups different in terms of research design?
A. Diet plan.
B. Professional background.
C. Exercise type.
D. Previous physical condition.
3. What does Levine's research find?
A. Middle-aged hearts get younger with aerobic exercise.
B. High-intensity exercise is more suitable for the young.
C. It is never too late for people to start taking exercise.
D. The more exercise we do, the stronger our hearts get.
4. What does Dr. Nieca Goldberg suggest?
A. Making use of the findings.
B. Interviewing the study participants.
C. Conducting further research.
D. Clarifying the purpose of the study.
答案：1.D 2.C 3.A 4.C
解析：
1. Levine说橡皮筋刚开始有弹性，放20年变干易断，“That's what happens to the heart.”他以此类比心脏随着老化而失去弹性，因此他想解释心脏的老化过程，选D。
2.根据第三段“The first group participated in a program of nonaerobic exercise... The second group did high-intensity aerobic exercise”可知，两组的区别在于运动类型不同，选C。
3.第三段提到第二组（有氧运动）两年后心脏健康显著改善，第四段Levine说“We took these 50-year-old hearts and turned the clock back to 30-or 35-year-old hearts”，说明有氧运动使中年心脏年轻化，选A。
4.最后一段Goldberg说“But the study was small and needs to be repeated with far larger groups of people”，因此她建议进行进一步的研究，选C。

Some parents will buy any high-tech toy if they think it will help their child, but researchers said puzzles help children with math-related skills. Psychologist Susan Levine, an expert on mathematics development in young children at the University of Chicago, found children who play with puzzles between ages 2 and 4 later develop better spatial skills. Puzzle play was found to be a significant predictor of cognition after controlling for differences in parents' income, education and the amount of parent talk, Levine said. The researchers analyzed video recordings of 53 child-parent pairs during everyday activities at home and found children who play with puzzles between 26 and 46 months of age have better spatial skills when assessed at 54 months of age. "The children who played with puzzles performed better than those who did not, on tasks that assessed their ability to rotate and translate shapes," Levine said in a statement. The parents were asked to interact with their children as they normally would, and about half of children in the study played with puzzles at one time. Higher-income parents tended to have children play with puzzles more frequently, and both boys and girls who played with puzzles had better spatial skills. However, boys tended to play with more complex puzzles than girls, and the parents of boys provided more spatial language and were more active during puzzle play than parents of girls. The findings were published in the journal Developmental Science.
