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?

| B．People's mental abilities begin to get worse at 27. |
| C．People's mental abilities have nothing to do with age. |
| D．Many people don't know what cause mental abilities' falling. |

| A．the difference of males and females |
| B．ways to help the people find better jobs |
| C．better ways to treat dementia of some old people |
| D．age has an effect on performance of mental abilities |
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 |
| D．only the ability of memory |

Attempt a guess at the following question: In the English-speaking world, which country has the least affordable homes? You are wrong if you guessed the US, even with the housing bubble （气泡） and main sadness. Nor is it the UK, where prices have risen because demand is far from supply. According to a recent survey of 227 cities around the globe, you must go south of the equator （赤道） to Australia to find the priciest homes．
The report measured a city’s housing market along the following guidelines. An “affordable” home required three times or less of the average family’s income to purchase. At four times earnings, a home fell into the “unaffordable” category. And a “seriously unaffordable” home needed five times a family’s income. In Australia, homes in the least affordable city cost just about 9.5 times the average income. Sydney, Perth, and Melbourne were only a little under this figure．
Australian officials offered little comment, apart from a general statement on the dismal findings. These prices make the possibility that many Australians will one day own a home largely unbelievable. Land rationing （配给制） and excessive development charges have raised prices, and the problem will only be solved through urgent action by the Rudd government．
Some American cities were also included on the least affordable list, four of which were in California. America is still involved in a mortgage（抵押）crisis, though, affecting the affordability of homes. Yet a number of US cities garnered “affordable” status, namely Dallas and Kansas. Australia had no cities listed in the top fifty places with affordable homes．
The survey suggests that you can find affordable homes in most places, just not if you’re Australian and choose to live down under．To buy an affordable house, you should pay _____．
| A．3 times or less of the average family’s income |
| B．4 times or less of the average family’s income |
| C．5 times or less of the average family’s income |
| D．9.5 times or less of the average family’s income |
What caused the prices of houses to increase in Australia?
| A．The rising family’s income． |
| B．The demand over supply. |
| C．The excessive development charges． |
| D．The decrease of land． |
The underlined word “dismal” in Paragraph 3 may mean _____．
| A．cheerful | B．satisfactory |
| C．difficult | D．sad |
What might be the most suitable title for the passage?
| A．Affordable Houses | B．A House is a Dream First |
| C．Housing Bubble | D．Homes Too Expensive |
Do you know what really troubles me? For some reason, words with silent letters have always bothered me. For example, consider these words: know, design, island, school, wrist, naughty, and salmon. All of these words have at least one letter that is not typically pronounced, and these words are just a very small part of words with silent letters in them.
Some words are even worse, consider this word: colonel. Not only are some letters not pronounced, but letters that are not even there are pronounced.
Even foreign languages, especially French, are guilty of this needless complexity and confusion. I know there must be some main historical reasons why the words are spelled and pronounced the way they are, but that does not mean bad traditions must continue to survive. Especially if they are no longer logical.
Unfortunately, there is very little that anyone can do for it, because there’s no group of people who can change or have the right to change the English language for everyone. However, the only thing we can do is make changes in the way we talk and write in hopes that it catches on. For example, I pronounce the letter “l” in salmon on purpose to make people annoyed and to sound more different or complicated. I even pronounce colonel the correct or French way.
I can only hope these two minor changes to the English language make sense to you, and you will help to keep up these minor changes forever in your everyday life.Which of the following is the main reason for silent letters?
| A．French language. | B．Historical reasons. |
| C．Some linguists | D．Bad traditions. |
The underlined phrase “catches on” probably means “________”.
| A．becomes popular | B．gets across |
| C．follows the fashions | D．doesn’t fall behind |
Which of the following is the best title for this passage?
| A．Troubles in everyday life |
| B．Traps in English words |
| C．Words with silent letters |
| D．Necessary changes of languages |

In 1939 two brothers, Mac and Dick McDonald, started a drive-in restaurant in San Bernadino, California. They carefully chose a busy corner for their location. They had run their own businesses for years, first a theater, then a barbecue(烤肉) restaurant, then another drive-in. But in their new operation, they offered a new, shortened menu: French fries, hamburgers, and sodas. To this small selection they added one new idea: quick service, no waiters or waitresses, and no tips.
Their hamburgers sold for fifteen cents. Cheese was another four cents. Their French fries and hamburgers had a remarkable uniformity(一致性), for the brothers had developed a strict routine(程序) for the preparation of their food, and they insisted on their cooks sticking to their routine. Their new drive-in became surprisingly popular, particularly for lunch. People drove up by the hundreds during the busy noontime. The self-service restaurant was so popular that the brothers had allowed ten copies of their restaurant to be opened. They were content with this modest success until they met Ray Kroc.
Kroc was a salesman who met the McDonald brothers in 1954, when he was selling milkshake-mixing machines. He quickly saw the special attraction of the brothers’ fast-food restaurants and bought the right to franchise(特许经营) other copies of their restaurants. The agreement included the right to duplicate(复制) the menu, the equipment, even their red and white buildings with the golden arches(拱门).

Encouragement and praise can come in many forms, and some ways are better for child development than others. Researchers at the University of Chicago who studied mother-child interactions (互相作用) found that the type of praise children receive affects their attitudes towards challenges later in life.
Specifically, praise that focused on their behavior and the choices that kids made helped them deal with difficult experiences better five years later, compared with praise that focused more on the child himself, like “You’re a good boy.” The study, which appears in the journal Child Development, is the first major study of praise and child development done outside of a lab setting.
“It’s exciting to see it play out in the real world,” said Elizabeth Gunderson who led the study. “Praising the efforts, actions and work of kids is going to be more beneficial in their long-term persistence and desire to be challenged and work hard in the future.”
Such “process praise” includes comments such as “You worked really hard”, which emphasize a child’s actions. “Person praise” includes comments like “You’re so smart”, which focus on a child’s personal qualities. These distinctions (差别) aren’t new in the field of psychology, but exactly how they affect children’s development over the years hasn’t always been clear.
As part of the study, the researchers visited the homes of more than 50 kids between the ages of 1 and 3, and filmed their daily interactions with their parents during 90-minute sessions. Five years later, the researchers followed up with the families, measuring the children’s attitudes towards challenges and problem solving. The children who grew up with more process praise were more open to challenges. Though person praise didn’t seem to have any negative effect on the children, the study suggests that process praise teaches children that their talents and abilities can be developed and improved, while person praise sends the message that their abilities are fixed and therefore not easily changed.What can we learn from the first Paragraph?
| A．Researchers encourage more mother-child interactions. |
| B．Different kinds of praise have different effects on children. |
| C．Encouragement and praise have the same effects on children. |
| D．Researchers have different attitudes to children’s development. |

Which of the following belongs to "progress praise"?
| A．You did a good job! | B．What an adorable boy! |
| C．You're a real gentleman! | D．We are so proud of you! |
Which of the following can be the best title for the text?
| A．Praise is good for children's development. |
| B．Praise is more beneficial than punishment. |
| C．Person praise is better than process praise. |
| D．Process praise is more beneficial in the long run. |
