Question

【题目】 As individuals age, many will experience decreased memory abilities.【1】Some signs include forgetting phone numbers, misplacing car keys, and struggling with name recall. This decline is associated with a routine that leaves parts of the brain unused. Memory exercises can help keep typically unused parts of the brain active and improve memory abilities.

【2】It can be something as simple as going to a new restaurant for lunch, cooking something completely new, or visiting a friend in the next town for the weekend. New sensory stimulation can help refresh memory.

Another easy way to improve memory is to use one's non-dominant hand to do simple tasks. For example, if one is right-handed, the left hand could be used to brush teeth or comb hair.【3】But in fact, a part of the brain is being used that is rarely put to work, making the brain stronger.

【4】This might include studying a new language or researching how to do a math problem. And it does not have to be something traditionally thought of as brain stimulating. Learning a new craft or sport may also activate the brain in new ways.

Not only can mind exercises improve memory, but physical exercise can as well. Studies show that exercise can improve memory abilities as it increases blood circulation and therefore more oxygen can reach the brain.【5】

A.This may feel slow and ineffective.

B.Short-term memory is often the first to suffer.

C.Talking with others can also improve one's memory.

D.Even as little as 30 minutes of walking each day can help.

E.Memory exercises can also be accomplished by learning new things.

F.One type of memory exercise involves changing one's regular routine.

G.Being alone can cause stress and depression，which affects memory negatively.

【解析】

这是一篇选句填空。随着年龄的增长，许多人的记忆能力会下降。文章介绍了几种提高记忆力的方法。

【1】根据上文As individuals age, many will experience decreased memory abilities.可知随着年龄的增长，许多人的记忆力会下降。由此可知，本句应当承接上文说明人哪方面的记忆最先受到损害。故B选项“短期记忆往往最先受到损害的”符合上下文语境，故选B。

【2】根据后文It can be something as simple as going to a new restaurant for lunch, cooking something completely new, or visiting a friend in the next town for the weekend. New sensory stimulation can help refresh memory.可知它可以是一些简单的事情，比如去一家新餐馆吃午饭，烹饪一些全新的东西，或者周末去拜访另一个城市的朋友。新的感官刺激可以帮助刷新记忆。由此可知，本段说明的记忆训练是指改变一个人的日常规律来进行的。故F选项“一种记忆训练包括改变一个人的日常规律”符合上下文语境，为短文标题。故选F。

【3】根据上文For example, if one is right-handed, the left hand could be used to brush teeth or comb hair.可知例如，如果一个人是右撇子，左手可以用来刷牙或梳头。以及后文But in fact, a part of the brain is being used that is rarely put to work, making the brain stronger.可知但是事实上，大脑的一部分很少被使用，这使得大脑更强壮。由此可知，本句应当承接上文说明上文这种做法给人的 感受是：可能会让人觉得缓慢和无效，但是实际上可以让大脑更强壮。故A选项“这可能会让人感到缓慢和无效”符合上下文语境，故选A。

【4】根据后文This might include studying a new language or researching how to do a math problem. And it does not have to be something traditionally thought of as brain stimulating. Learning a new craft or sport may also activate the brain in new ways.可知这可能包括学习一门新语言或研究如何做一道数学题。它并不一定是传统意义上的大脑刺激。学习一门新手艺或运动也可能以新的方式激活大脑。由此可知，本段说明的是通过学习新事物来进行记忆练习。故E选项“记忆练习也可以通过学习新事物来完成”符合上下文语境，为短文的标题。故选E。

【5】根据上文Studies show that exercise can improve memory abilities as it increases blood circulation and therefore more oxygen can reach the brain.可知研究表明，锻炼可以提高记忆能力，因为它可以增加血液循环，因此更多的氧气可以到达大脑。由此可知，本句为本段最后一句，有承接上文的作用，上文提到了锻炼可以提高记忆能力，可知本句应当是举出实际锻炼的时间来说明上述观点。故D选项“即使每天步行30分钟也会有所帮助”符合上下文语境，故选D。
