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

B. This can be especially harmful to the aged.

C. It should be something like learning gardening.

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

E. Focus on the future.

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

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

【答案】

【1】G

【2】E

【3】A

【4】F

【5】C

【解析】

試題分析：本文介紹了如何使自己的大腦處于一個反應(yīng)敏捷的狀態(tài)，本文從3個維度給大家提供了一些小建議。

【1】G 該空前面介紹的是我們的大腦會隨著年齡的增長，大腦反應(yīng)逐漸會變得遲緩的道理，而該空后面是描述如何使自己的大腦保持一個比較敏捷的狀態(tài)，前后兩句需要一個句子來緩沖，所以G項就提出了專家學(xué)者發(fā)現(xiàn)避免這種的方法。

【2】E 根據(jù)下文的In other words, keep your brain looking forward...可以看出該段的主旨是關(guān)注未來。

【3】A Something as simple as setting a goal to have a weekly coffee date with a friend will do.指的是我們可以像和朋友約著一塊去哈咖啡那樣簡單...所以備選項中的A就是寫出了不必?fù)?dān)心時間被占用。

【4】F 該空所在的段落，大概是講述的walking is good for you healthy,所以多動對你的身體很有好處，要學(xué)會照顧自己的身體。

【5】C 作者在斷尾把learn something new比做成go dancing，而在備選項當(dāng)中這樣的比喻手法只有C項符合。

When Joe left university, he got a good job in a bike’s factory. And after he had worked there for some years, he decided to have a change. So he put a notice several newspapers, says what experience he had and the kind of job he would like to have. One of the answer he received was from a man who was looking for a job either. This man wrote to him, “Dear sir, when you get a new job, to be kind enough to give your name and address to your present boss as I have been trying to find a position like yours for a long time.” After he had finished reading the letter, he suddenly realizes what he had done was real foolish.

【題目】閱讀理解。

閱讀下列四篇短文，從每小題后所給的A、B、C、D四個選項中，選出最佳選項，并在答題卡上將該選項涂黑。

People think being an artist must be a wonderful way to earn one’s living. And of course, there are lots of great things about working for oneself, at home alone, even in a cold studio like mine. What I really like is that nobody tells me what time to start in the morning. I like to paint as soon as I wake up, which is always early, but isn’t the same time every day. And nobody tells me what to wear or whether I can take the afternoon off and go to a football match.

But then, I have no one to chat with when I’m bored, no one to discuss last night’s match with during the office lunch hour. Sure, I can spend the afternoon doing something I enjoy like cycling or gardening if I choose. But the work will still be there when I do finally get back home.

Unfortunately, working at home means that people can always find me, whether I’m bored or not, and once I’ve answered the doorbell, it’s too late — my thoughts have been interrupted. No one would dream of calling in if I worked in an office, but I find myself listening to friends’ troubles. As they talk, my ideas disappear and I feel increasingly stressed thinking of my work waiting to be done.

However, when I hear the traffic news on the radio, and imagine my friends sitting miserably in their cars in a jam, feeling bored, or waiting unhappily for an overcrowded train in the rain, I realize that I really haven’t got much to complain about. I find a CD which will start me thinking, turn it up really loudly and begin another picture.

【1】 In the passage the writer is trying to ________.

A. encourage readers to work at home

B. explain why he decides to be an artist

C. describe his working life

D. show how he begins a picture

【2】What does the writer like about his working life?

A. He has plenty of opportunities for sport.

B. He can do things without being told by others.

C. He needn’t work in the morning.

D. He has a comfortable place to work in.

【3】The writer plays loud music because ________.

A. the traffic outside is noisy

B. it helps him to have ideas

C. it prevents him from feeling bored

D. he doesn’t want to hear the doorbell

【4】Which of these notices would be the most useful for the writer to put on his door?

A. I’m working — please don’t disturb.

B. Please knock before entering.

C. I’m listening to music — join me.

D. Come in and have a chat.

【題目】Sooner or later, most students are to take some form of English examinations. Often the more successful students are better prepared. However, sometimes students who do well have better test taking skills. These abilities really have nothing to do with understanding English better. They are skills that make taking the test easier, and therefore provide better results.

Here are some very important—and often ignored—guidelines to taking a test successfully.

Do not insist on completing each question before going to the next. This is extremely important. Remember one question may only be worth one point! You will become nervous when you fail to find out its answer, making you lose your concentration and leading to worse results.

Go through the test a second time working out the answers to more difficult questions. Sometimes questions asked are answered in later questions asking for different things.

Usually(but not always) a strong first impulse(沖動) means we know the answer and we don’t really have to think about it too much. Going back to think about it usually makes you unsure and often causes a mistake. This is very common, so be very careful!

If you don’t know the answer, write something. If you are answering a 4 possibility multiple choice question you will still have a 25% chance of being correct!

Taking a test is as much for you as is for your teacher, so never cheat. If you cheat, you don’t help yourself in the long run.

【1】In the first paragraph, the writer stresses the importance of ______.

A. better preparations for exams.

B. better understanding of English.

C. better skills at taking exams.

D. better results of taking exams.

【2】When taking an exam, you are advised ______.

A. to first answer the questions which are easier to you.

B. to depend on your first impulse to answer the questions.

C. to search the test paper for all the answers to the questions.

D. to give up the questions whose answers you don’t know.

【3】It is common that many students______.

A. pay much attention to their testing skills.

B. often give up a difficult test halfway.

C. often get higher results by cheating.

D. don’t believe in their first impulse.

【4】What would be the best title of the passage?

A. Effective Studying Methods.

B. Effective Test Taking Skills.

C. Getting Better Exam Results

D. Being Successful Students.
