Question

【題目】Are you preparing for a big test? If so, you may want to go to play some basketball in between hitting the books. Doctors are starting to find more and more information that suggests a connection between exercise and brain development. Judy Cameron, a scientist at Oregon Health and Science University, studies brain development. According to her research, it seems that exercise can make blood vessels, including those in the brain, stronger and more fully developed. Dr. Cameron is sure that this allows people who exercise to think better. As she says, “While we already know that exercise is good for the heart, exercise can actually cause physical changes in the brain.”

The effects of exercise on brain development can even be seen in babies. Babies who do activities that require a lot of movement show greater brain development than babies who are less physically active. Even a little movement can show big results. Margaret Barnes, a scientist, also believes in the importance of exercise. She thinks that many learning disabilities that children have in primary school or high school can result from a lack of movement as babies. Babies need movement that encourages and excites their five senses. They need to set up a connection between motion and memory. In this way, as they get older, children will begin to connect physical activity with higher learning,” says Margaret.

Older people can develop their brains as well. Cornell University studied a group of seniors who have a short-term memory increase of up to 40 percent after exercising just three hours a week. The exercise does not have to be very difficult, but it does have to increase the heart rate. Also, just like the motion for babies, exercise for older people should not be too simple. Learning some new skills or actions, such as with yoga or tai-chi helps to open up memory paths in the brain that may not have been used for a long time. For most people, any type of physical activity that increases the heart rate is helpful. The main aim is to increase the brain’s flow of blood. And your brain can benefit from as little as two to three hours of exercise a week.

根據(jù)事實細節(jié)，推斷合理信息。推理題要求在理解原文表面文字信息的基礎(chǔ)上，作出一定判斷和推論，從而得到文章的隱含意義和深層意義。推理題所涉及的內(nèi)容可能是文中某一句話，也可是某幾句話，但做題的指導(dǎo)思想都是以文字信息為依據(jù)，既不能做出在原文中找不到文字根據(jù)的推理，也不能根據(jù)表面文字信息做多步推理。也就是說，要做到判斷有據(jù), 推論有理, 忠實原文。切忌用自己的觀點代替作者的本意，切忌片面思考，得出片面結(jié)論。

【解析】 考查健康類文章。本文敘述了運動有助于大腦的生長。

【1】C

主旨大意題。根據(jù)第一段As she says, “While we already know that exercise is good for the heart, exercise can actually cause physical changes in the brain.”第二段第一句“.The effects of exercise on brain development can even be seen in babies”和第三段的第一句“Older people can develop their brains as well.”可知，本文從各方面闡述了運動有助于大腦生長，故選C項。

【2】C

推理判斷題。第三段中Learning some new skills or actions, such as with yoga or tai-chi helps to open up memory paths in the brain that may not have been used for a long time.．學(xué)習(xí)一些新的技能或動作，比如瑜伽或太極，有助于打開大腦中可能很長時間沒有使用的記憶路徑。分析句意可知對于老年人來說瑜伽有助于幫助記憶新的東西。分析選項可知，C為正確答案

【3】A

【解題剖析】此題屬于推理判斷題中的（4）根據(jù)事實細節(jié)，推斷合理信息。答案需要從文章的For most people, any type of physical activity that increases the heart rate is helpful….And your brain can benefit from as little as two to three hours of exercise a week 進行推斷。

【答案定位】根據(jù)本文最后一段最后一句“For most people, any type of physical activity that increases the heart rate is helpful….And your brain can benefit from as little as two to three hours of exercise a week”可知，對于大多數(shù)來說，大腦可以從每周兩到三小時的運動中獲益。

【推理關(guān)系】題干For most people, the smallest amount of exercise required to gain any benefit is _____..文章內(nèi)容And your brain can benefit from as little as two to three hours of exercise a week
