Question

【題目】根據(jù)短文內容，從短文后的選項中選出能填入空白處的最佳選項。選項中有兩項為多余選項。

A strong memory depends on the health and vitality （活力） of your brain. They say that you can’t teach an old dog new tricks, but when it comes to the brain, scientists have discovered that this old saying simply isn’t true. 【1】

Give your brain a workout. Memory, like muscular strength, requires you to “use it or lose it”. The more you work out your brain, the better you’ll be able to process and remember information. 【2】

Don’t skip the physical exercise. While mental exercise is important for brain health, that doesn’t mean you never need to break a sweat. Physical exercise helps your brain stay sharp. It increases oxygen to your brain and reduces the risk for disorders that lead to memory loss.

Get enough sleep. There is a big difference between the amount of sleep you can get by on and the amount you need to function at your best. 【3】

Keep stress in check. Stress is one of the brain’s worst enemies. Over time, stress destroys brain cells. Studies have also linked stress to memory loss.

Have a laugh. 【4】 That holds true for the brain and the memory, as well as the body. Unlike emotional responses, which are limited to specific areas of the brain, laughter engages multiple regions across the whole brain.

【5】 Just as the body needs fuel, so does the brain. You probably already know that a diet based on fruits, vegetables, whole grains, “healthy” fats and lean protein will provide lots of health benfits, but such a diet can also improve memory. For brain health, though, it’s not just what you eat—it’s also what you don’t eat.

A. Eat a brain-boosting diet.

B. Play games with memory.

C. Laughter is the best medicine.

D. But oversleeping is not good for your brain.

E. Even skipping a few hours makes a difference!

F. You have to shake things up from time to time!

G. The human brain has an astonishing ability to adapt and change.

試題分析:文章給我們介紹了幾種讓腦子靈活的幾種方法。

【1】G根據(jù)該空格前一句說“you can’t teach an old new tricks”意思是說“老年人很難適應新事物”，而后面又說科學家發(fā)現(xiàn)這種說法是不對的，可推斷此處說就是其實人腦會改變的。結合各個選項的意思，可知G正確。

【2】 F根據(jù)前一句說“The more you work out your brain, the better you’ll be able to process and remember information”，結合各個選項的意思，故可選F。

【3】E根據(jù)本段講述的內容是關于睡眠的，結合各選項意思，故E為正確答案。

【4】C根據(jù)該空格后一句中的laugh一詞，結合各個選項的意思，可知C選項中的Laughter is the best medicine，故選C。

【5】A根據(jù)該空格后一句說大腦和身體一樣都需要能量。而A選項就是講這個話題的，故可知A為正確選項。
