IV. Reading comprehension: 24% (每題 2 分)
(A) Do you know that jogging regularly is good for your memory? Scientists at Cambridge University have shown thatrunning makes the brain grow fresh grey matter and it has a big effect on mental ability.According to their research, a few days of running led to the growth of hundreds of thousands of brain cells that improvedthe ability to recall memories without confusing them, a skill that is very important for learning and other cognitive tasks,researchers said. P. 4The new brain cells appeared in an area that is linked to the formation and recall of memory. The work reveals whyjogging and other aerobic exercise can improve memory and learning, and potentially slow down the failure of mental ability inold age.Scientists are unsure why exercise causes the growth of grey matter, but it may be linked to increased blood flow orhigher levels of hormones that are released while exercising. In an experiment, they studied two groups of mice, one of whichhad unlimited access to a running wheel throughout. The other mice, remained sedentary, formed another group.After training sessions, the mice in the exercising group scored almost twice as highly as the other mice in a repeatedmemory test for a sugar reward. On the other hand, the sedentary mice gradually worsened at the test. To sum up, exercisingregularly not only can help us lose some extra fat, but it can also help us build up better memory. So before each exam, besidesstudying at your desk, try going for a run every day, and you may be surprised by how much more you can remember fromyour textbook!
