Question

【題目】 Your brain isn’t a muscle, but you can treat it like one

Many people focus on physical fitness, but few know that brain fitness is also something you can work on. In fact, you can exercise your brain as often as you do to your arms or legs-and the results can be positive and empowering.

To improve your brain, you can’t simply repeat the same exercises over and over. Just as lifting a two-pound weight will stop challenging you, so will repetitive exercises such as crosswords or Sudoku. Once you master easy exercises, you must move on to harder ones in order to push your brain-like your muscles-to a new level.

The science behind brain training

Scientists once believed that your mental abilities were fixed in adulthood. Since studies have shown just the opposite, millions of people around the world have adopted the new practice of brain training. The most popular of these brain training products is made by the San Francisco-based Lumosity. Lumosity’s scientists with an experienced team of game designers have developed a fun，effective online brain training program that measures, tracks, and adapts to your progress, so you’ll always be challenged.

Promising studies on the effects of brain training

In a 2013 Stanford study, a treatment group of 21 breast cancer survivors used 12 weeks of Lumosity training to work on processing speed, mental flexibility, and working memory tasks. On average, those who trained improved on tests of these abilities, compared to a group that did not train with Lumosity.

There is even some evidence suggesting that Lumosity may be beneficial to normal, healthy adults. In a 2011 study by Lumosity and San Francisco State University researchers. 13 people who trained over 5 weeks improved working memory scores by 10％and attention scores by 20％.

Brain training is designed to meet real-life needs

The design of brain train ing is targeted at real-life benefits instead of improving game scores. Better attention, for example, can mean greater focus in the classroom or at an important business meeting. With improved processing speed, you might react and adapt faster to the demands of a busy life. And a better memory could mean stronger, longer relationships with the people closest to you.

Answer 1

【答案】

【1】D

【2】C

【3】B

【4】A

【解析】

試題分析：文章講述了大腦是可以經(jīng)過訓(xùn)練而提高的，甚至注意力，處理速度，記憶力都可以被訓(xùn)練。

【1】D。細(xì)節(jié)理解題。由文中effective online brain training program that measures, tracks, and adapts to your progress, so you’ll always be challenged. 可知有效的在線大腦訓(xùn)練程序，措施，跟蹤，和適應(yīng)你的進(jìn)步，所以你總是被質(zhì)疑。所以可知D符合題意。

【2】C細(xì)節(jié)理解題。由最后一段可知大腦訓(xùn)練的設(shè)計是針對現(xiàn)實生活中的利益而不是提高比賽成績。例如，可能意味著更好的注意，在課堂上或在一個重要的商務(wù)會議更大的關(guān)注。具有改進(jìn)的處理速度，你的反應(yīng)和更快地適應(yīng)繁忙的生活需求。和一個更好的記憶可能意味著更強(qiáng)，與你最親近的人的長期的關(guān)系可知文中沒有寫作能力，故選C。

【3】B推理判斷題。由第三段科學(xué)家們對大腦的研究可知B選項科學(xué)家們已經(jīng)證實大腦可以提高，故選B。

【4】A主旨理解題。由整篇文章都是寫大腦不是像我們想象的一樣，可知大腦可以訓(xùn)練，并且很獨特，可以推理出A符合題意。
