Question

    You know that eating healthy, staying active, and solving a few brain games can help keep your memory. But the following lesser-known habits work wonders too.

1. 1.

When we sit with our shoulders bent forward, this defeated position actually causes us to feel anxious or depressed — which makes it harder to think clearly and remember things. Conversely (反过来), straight upright posture apparently improves memory because it boosts blood and oxygen flow to the brain.

2. Exercise — Once

Having trouble remembering faces? 2. In a study, pictures of faces were shown to

older folks after they pedal a stationary (静止的) bike at an intense pace or simply sit on a self-pedaling bike. On average, people remembered the faces better after the intense exercise. What’s more, the memory gains after a single workout were similar to the gains after 3 months of regular exercise.

3. Limit TV

Every parent and grandparent has heard that too much screen time can hurt a child’s

cognitive development. 3. According to a study, people (aged 50 or older) who watched

more than 3.5 hours of TV a day for 6 years experienced a greater drop in verbal memory test scores than those who watched less.

4. Draw aimlessly

A research shows those who drew the words remembered the most when recalling words. That’s because while some parts of the brain about getting memory back become worse as people

grow older, the picture processing regions usually don’t. 4.

5. Walk Backward

5. Walk back! Backward motion — whether real, imagined, or watched — helps people remember the information better than sitting still and, in most cases, better than forward motion. It may be that moving backward in space mentally helps us move back in time to the moment we learned something.

A.Sit Tall.

B.Stand Straight.

C.Start more workouts.

D.Sweat for physical training.

E.Thus sketching can help adults keep their memory sharp.

F.But what about those at the other end of their life span?

G.Next time you’re trying to recall something, don’t just think back.

【解析】

本文是说明文。文章讲述了保持大脑记忆功能的一些方法。

1.考查段落标题。根据段落内容“当我们向前弯曲坐着时，这种姿势实际上会使我们感到焦虑或沮丧，这使得清晰思考和记住事情变得更加困难。相反，坐正的姿势显然可以改善记忆力，因为它可以促进血液和氧气流向大脑”。可知，A项（坐正。）能够概括本段内容。该选项中的sit一词在第二段中出现了，该段中的straight upright指的是坐姿要“端正”。故选A项。

2.考查段中句。根据空前“Having trouble remembering faces?（难以记住面孔吗？）”和空后“In a study, pictures of faces were shown to older folks after they pedal a stationary (静止的) bike at an intense pace or simply sit on a self-pedaling bike. On average, people remembered the faces better after the intense exercise. What’s more, the memory gains after a single workout were similar to the gains after 3 months of regular exercise.（在一项研究中，人脸的照片展示给以剧烈的速度踩踏静止的自行车或只是坐在自动踏板自行车上运动之后的老年人。一般来讲，剧烈运动后人们对面部的记忆更好。 而且，一次剧烈锻炼后对保持记忆力的好处与定期锻炼三个月后的效果是相似的。）”可知，D项（在进行体育锻炼时要出汗。）能够承接上文并且与下文连接通顺。该选项是对前面问题的回答，通过锻炼可以使保持记忆力，空格后是在讲一个具体的锻炼方法及它所带来的好处，D项的physical training与本段的regular exercise是相关表达。故选D项。

3.考查段中句。根据空前“Every parent and grandparent has heard that too much screen time can hurt a child’s cognitive development.（每个家长和祖父母都听说过对着荧幕时间过久会伤害孩子的认知发展。）”和空后“According to a study, people (aged 50 or older) who watched more than 3.5 hours of TV a day for 6 years experienced a greater drop in verbal memory test scores than those who watched less.（根据一项研究，年龄在50岁以上的人每天观看电视超过3.5个小时，如持续6年，其语言记忆力测试成绩的下降幅度要比收看较少的人更高。）”可知，F项（那年龄较大的人呢？）能够承接上文并且与下文连接通顺。该选项中的“those at the other end of their life span”指的是空格后的people (aged 50 or older)。故选F项。

4.考查段尾句。根据空前“A research shows those who drew the words remembered the most when recalling words. That’s because while some parts of the brain about getting memory back become worse as people grow older, the picture processing regions usually don’t.（一项研究表明，那些画字词的人对单词的记忆最深。那是因为随着人们年纪变大，大脑的某些部位的记忆功能变得更糟，而负责图片处理的大脑区域通常不会。）”可知，E项（因此，画字词可以帮助成年人保持清晰的记忆。）能够承接上文。该选项中的sketching与第五段的标题draw及该段中的drew是同义词，即描绘。故选E项。

5.考查段首句。根据空后“Walk back! Backward motion helps people remember the information better than sitting still and, in most cases, better than forward motion.（向后走！向后运动比起静止不动并且在大多数情况下比向前运动更能帮助人们记住信息。）”可知，G项（下次您想回忆某件事时，不要只是通过大脑来回忆。）能够与下文连接通顺。该选项中的back在空格后的句子中出现了。故选G项。
