Researchers have found that people's mental abilities hit the highest point at 22 before beginning to get worse just five years later.
Professor Timothy Salthouse said the results told us that treatment which was planned to prevent or make overage-connected conditions better may need to start earlier, long before people become retired (退休).
"Almost half of those over 50 is not clear about the main cause of the fall of mental abilities. Results show that the age-connected cognitive decline (认知衰退) begin in healthy, educated adults when they are in their 20s and 30s, " he said. Tests like those are often used to show mental disabilities and the falling, including dementia (痴呆症).
The research by the University of Virginia found that in nine out of 12 tests the common age at which the top performance appeared was 22.
The first age at which performance was much lower than the highest scores was 27—for three tests about reasoning, speed of thought and space imagination.
Memory was shown to fall from the average age of 37. In the other tests, poorer results were shown by the age of 42.
However, the report published in the magazine "Neurobiology Of Ageing", found that abilities that are based on collected knowledge, such as performance on tests of getting vocabulary (词汇) or general information, increased until at the age of 60.
The study of 2, 000 men and women lasted over seven years. The people attending the study, aged between 18—60, were asked to do picture puzzles, remember words and stories and mark patterns in letters and signs.
Twenty-seven has long had unhelpful connotations (隐含意义), as it is the age at which many popular musicians died, including Jimi Hendrix, Jim Morrison, Brian Jones, Janis Joplin and Kurt Cobain. Which of the following is NOT true?

People at the age of 27 perform worse mainly at __________.
A.reasoning, speed of thought and space imagination |
B.getting vocabulary or general information |
C.all of the mental abilities |

Meeting people from another culture can be difficult. From the beginning, people may send the wrong signal(信号). Or they may pay no attention to signals from another person who is trying to develop a relationship.
Different cultures emphasize(强调)the importance of relationship building to a greater or lesser degree. For example, business in some countries is not possible until there is a relationship of trust. Even with people at work, it is necessary to spend a lot of time in "small talk", usually over a glass of tea, before they do any job.In many European countries -- like the UK or France -- people find it easier to build up a lasting working relationship at restaurants or cafes rather than at the office.
Talk and silence may also be different in some cultures. I once made a speech in Thailand.I had expected my speech to be a success and start a lively discussion; instead there was an uncomfortable silence. The people present just stared at me and smiled.After getting to know their ways better, I realized that they thought I was talking too much. In my own culture, we express meaning mainly through words, but people there sometimes feel too many words are unnecessary.
Even within Northern Europe, cultural differences can cause serious problems. Certainly, English and German cultures share similar values; however, Germans prefer to get down to business more quickly. We think that they are rude. In fact, this is just because one culture starts discussions and makes decisions more quickly.
People from different parts of the world have different values, and sometimes these values are quite against each other. However, if we can understand them better, a multicultural environment will offer a wonderful chance for us to learn from each other.In some countries, eating together at restaurants may make it easier for people to _______.
A.develop closer relations | B.share the same culture |
C.get to know each other | D.keep each other company |
The author mentions his experience in Thailand to show that _______.
A.the English prefer to make long speeches |
B.too many words are of no use |
C.people from Thailand are quiet and shy by nature |
D.even talk and silence can be culturally different |
According to the text, how can people from different cultures understand each other better?
A.By sharing different ways of life. |
B.By accepting different habits. |
C.By recognizing different values. |
D.By speaking each other' s languages. |
What would be the best title for the text?
A.Multicultural Environment. |
B.Cross-Cultural Differences. |
C.How to Understand Each Other. |
D.How to Build Up a Relationship. |
A good first impression is important. So, how do you, when you’re meeting someone for the first time, make certain he or she doesn’t get the wrong image of you?
A study concluded that the first 30 seconds make or break the connection between two people when they meet for the first time. Another study conducted by UCLA found that “people evaluate one another by using the three V’s: visual (appearance), vocal (voice) and verbal (what you say).”
Before you head out on your next date to meet someone new, let’s concentrate on these areas:
●How others will see you. (Visual) Are you dressed well? Do you look like this date is important to you? Did you take some time with your appearance? Watch your manners: people don’t like bad manners.
●How others will hear you. (Vocal) Is your voice too soft? You might come across as insecure. If you speak softly, make an effort to speak clearly — don’t make your date have to work to hear you.
●What others will hear you say. (Verbal) People have a natural desire to connect — let them know you’re interested in what they have to say by repeating it back to them. Don’t say the same thing everyone else is saying.What would be the best title for the text?
A.How to make friends with others |
B.How to enjoy yourself in your life |
C.The importance of a good first impression |

Some people think that all wild animals are very dangerous. Actually, very few of them will attack a man if he leaves them alone. If you met a lion or an elephant, suppose, you would run away, but even a lion will keep away from a man unless it is very hungry. Lions and tigers only kill and eat men when they have grown too old and too weak to catch their usual food, such as deer and other small animals. If you saw a wild elephant, perhaps you would be frightened. Elephants usually run away at once unless you attack them. Some animals get very frightened if they only smell a man; some take no notice at all but quietly walk in another direction. Wild animals only attack hunters when they are afraid that the hunters mean to harm their young ones, or then the hunters shoot at them and make them angry.The word “attack ’’ is closest in meaning to _____________ .

Some people bring out the best in you in a way that you might never have fully realized on your own. My mother was one of those people.
My father died when I was one-year-old. While I was growing up, we led a very hard life, but my mom gave me a lot of love. Each night, she seated me on her lap and spoke the words that would change my life, "Kemmons, you are sure to be a great man and you can do anything in life if you work hard enough to get it. "
At fourteen, I was hit by a car and the doctors said that I would never walk again. Every night my mother spoke to me in her gentle, loving voice, telling me whatever those doctors said, I could walk again if I wanted to. She drove that message so deep into my heart that I finally believed her. A year later, I walked on my own to school!
When the Great Depression broke out, my mother lost her job. Then I left school to support the two of us. At that moment I decided never to be poor again.
Over the years, I experienced a lot of business success. But the real turning point happened on a vacation I took with my wife and five kids in 1951. I was dissatisfied with the second-class hotels available for families and was very angry that they charged an extra $2 for each child. That was too expensive for an ordinary American family. I told my wife that I was going to open a motel (汽车旅馆)for families that would never charge extra money for children. Many people did not believe me at that time.
Not surprisingly, mom was my strongest supporter. As in any business, I experienced a lot of difficulties. But with my mom's words in my heart, I never doubted I would succeed. Fifteen years later, I had the largest hotel system in the world—Holiday Inn. In 1979 my company had 1,759 inns in more than fifty countries with an income of $l billion a year.
You may not have started out life in the best situations. But if you find a task in life worth working for and believe in yourself, nothing can stop you.What Kemmon's mother often told him during his childhood was____.
