Easy Ways to Keep Your Brain Sharp

Everyone is forgetful, but as we age, we start to feel like our brains are slowing down a bit — and that can be a very annoying thing. 【1】 Read on for some techniques worth trying.

1. 【2】

People who regularly made plans and looked forward to upcoming events had a 50 percent reduced chance of Alzheimer's disease (早老性癡呆癥), according to a recent study. 【3】 Something as simple as setting a goal to have a weekly coffee date with a friend will do. There’s evidence that people who have a purpose in life or who are working on long or short-term goals appear to do better. In other words, keep your brain looking forward.

2. Go for a walk.

Mildly raised glucose (葡萄糖) levels can harm the area of the brain that helps you form memories and physical activity can help get blood glucose down to normal levels. In fact, exercise produces chemicals that are good for your brain. 【4】

3. Learn something new.

Take a Spanish class online, join a drawing club, or learn to play cards. A study found that mental stimulation (刺激) limits the weakening effects of aging on memory and the mind. But the best thing for your brain is when you learn something new and are physically active at the same time. 【5】 Or go dancing with your friends.

A. Focus on the future.

B. This can be especially harmful to the aged.

C. It should be something like learning gardening.

D. So take span>a few minutes each day to do some reading.

E. But don't worry if your schedule isn't filled with life-changing events.

F. Luckily, research shows there is a lot you can do to avoid those moments.

G. In other words, when you take care of your body, you take care of your brain.

【5】C

【解析】

試題分析：每個(gè)人都可能健忘，但是隨著我們慢慢衰老，我們發(fā)現(xiàn)我們的腦子越來(lái)越遲緩，這非常惱人。但是最近的研究表明我們可以采取一些措施來(lái)避免這一情況。

【1】F 根據(jù)上文“我們的腦子越來(lái)越不好用”和下文“繼續(xù)讀一些可以避免這一現(xiàn)象的措施” 可知腦子遲緩是可以避免的，只有F項(xiàng)有此意。

【2】A 根據(jù)下一句中made plans and looked forward to upcoming events可知是要“著眼未來(lái)”，故選A。

【3】E 與前一句中l(wèi)ooked forward to upcoming events轉(zhuǎn)折，生活中并不是總是充滿 會(huì)改變?nèi)松氖录?/span>

【4】G 根據(jù)上文Mildly raised glucose (葡萄糖) levels can harm the area of the brain that helps you form memories and physical activity can help get blood glucose down to normal levels.可知：鍛煉能產(chǎn)生有益大腦的化學(xué)物質(zhì)，后一句是進(jìn)一步說(shuō)明，故 G 項(xiàng)正確。

【5】C 根據(jù)上句But the best thing for your brain is when you learn something new and are physically active at the same time. 可知對(duì)大腦最好的事情是你學(xué)新東西時(shí)，身體也要?jiǎng)�，即腦力勞動(dòng)和體力勞動(dòng)相結(jié)合的事，就像學(xué)習(xí)園藝以及和朋友跳舞這樣的事情。選C.

【題目】I grew up in a family that ate dinner together every evening. Although my parents enjoyed wine, they rarely drank during the week and always in moderation（節(jié)制）.As for myself,1 wasn't interested in alcoholic drinks and neither were my high school friends.

So when I arrived on campus for my first year of university life, I was a bit shocked. Many different events had been organized for the freshmen, but they all had one thing in common-alcohol, and plenty of .it wanting to be left out, I joined a few of the events. But I always returned home early, feeling disappointed. Your personality, interests and experiences didn't matter at all, only how many alcoholic drinks you could absorb before passing out（喝醉）. It seemed shallow to me. I wanted to get to know my new coursemates, not how fast they. could down a pint of beer.

Gradually, however, I realized that real friends don't judge you by how much you can drink and there were other ways of making friends. I joined a photography society, took a first aid course, and every weekend l went cycling with a coursemate. I found that by engaging in these activities and sharing the fun of learning new skills together in a group ,I formed much stronger bonds with my new friends than even the strongest alcoholic drinks could encourage.

Another valuable lesson I learned is that it's perfectly okay to say "No" if you don't want to drink. However, in many Western societies, especially the UK, binge drinking（狂喝）has become the norm. Many people who drink don't necessarily want to, but they give in to the peer pressure(同伴壓力)-they're afraid to say "No".

【1】What shocked the author when he entered university?

A. The strange campus. B. The popularity of alcohol.

C. The drunken coursemates. D. The limited activities.

【2】Why did the author return home early from the events at first?

A. He wasn't good at drinking.

B. He had no familiar coursemates.

C. He hated the way people got along.

D. He was left out by the organizers.

【3】How did the author finally make real friends at university?

A. By saying "No" to alcoholic drinks.

B. By staying away from group activities.

C. By giving in to the peer pressure.

D. By joining people with common interests.
