A report says older adults who test their minds with increasingly difficult projects have better mental ability than those who do less demanding activities.
To keep our brains sharp as we age, we are often told to keep our minds active. As the old saying goes, “Use it or lose it.” But, there is very little scientific evidence to support than.
Denise Park is head of the university’s Center for ? Vital Longevity. She designed a study in which she and her tern placed 221 healthy aging and older adults into one of three groups.
“We asked people to learn new things, like quilting or photography. We asked other people to just do fun things like being in a social group function but were not likely to have a very large effect.”
The subjects took part in their assigned activities for 15 hours a week over three months. At the end of that time, the researchers found that the adults who learned new skills, such as digital photography, showed the greatest improvements on memory tests.
No improvements were seen in the results of those in the social group that did activities together like going on field trips. There were also no improvements among the third group that listened to classical music or did crossword puzzles.
Denise Park believes one reason for improved memory in the active learning group is that its members were being pushed to learn new skills. The other groups took part in what she call receptive activities. Learning new skills may not cure age-related mental decline. But, Ms. Park thinks being mentally active slows down the process.
Denise Park says the latest information shows that the improvements lasted for at least a year. She and her team plan to do longer follow-up studies with all three groups. She also is interested in learning whether taking part in demanding mental activities delays the development of conditions like Alzheimer’s disease.
1.What may the social group be asked to do?
A. Learn to take photos.
B. Listen to music at home.
C. Go hiking together.
D. Do the dishes.
2.What did Denise Park and her team find?
A. Doing more exercise can help slow down our age-related mental decline.
B. Having a relaxing life is beneficial to keeping our minds sharp.
C. Keeping our minds active is associated with our health.
D. Learning new skills may help to keep our minds active.
3.If you want to keep your brain sharp you could_______.
A. go swimming with your friends.
B. play chess with your family.
C. learn how to repair the computer.
D. do crossword puzzles online
4.The text is likely to be selected from a book of______.
A. medicine B. education

Older adults with a better sense of smell may live longer than those who have a poor sense of smell, a new study suggests. The study was a project of researchers in the United States that was ongoing for over 13 years. They asked nearly 2,300 men and women to identify 12 common smells. All the subjects were from 71 to 82 years of age. The researchers gave the adults scores, from 0 to as high as 12, based on how many smells they identified correctly.
During the years of follow-up investigation, over 1,200 of the subjects died. When the study was launched, none of the adults were weak. They could walk a little under half a kilometer, climb 10 steps and independently complete daily activities. In the latest findings, the researchers noted that those with a weak nose were 30 percent more likely to die than people with a good sense of smell. The findings were reported last month in the scientific publication Annals of Internal Medicine.
Honglei Chen, a doctor with Michigan State University in East Lansing, Michigan, was the lead writer of a report on the study. He said the connection between a poor sense of smell and an increased risk of dying was limited to adults who first reported good-to-excellent health. This suggests that a poor sense of smell is an early and sensitive sign for worsening health before it is recognizable in medical tests. With a poor sense of smell, people are more likely to die of brain and heart diseases, but not of cancer or breathing disorders.
The results also suggest that a poor sense of smell may be an early warning for poor health in older age that goes beyond dementia or other neurodegenerative(神经变性的) diseases. These often signal the beginning of a weakening of the mind or body.
1.What do you know about the study mentioned?
A.The study involved researchers from the world.
B.All the participants were of different ages.
C.The study began to be performed about 13 years ago.
D.2 ,300 men and women were young and healthy.

A.More than 1,200 of the participants passed away.
B.Many of the subjects were found with health problems.
C.All the subjects were independent of others when walking.
D.One third of the participants had a poor smell sense.
3.What can be inferred from the last two paragraphs?
A.People with a poor sense of smell have heart disease.
B.You should be careful with your health if you smell poorly.
C.People with a poor sense of smell won't suffer from cancer.
D.Most of the elder people may have the dementia disease.
4.Which is the best title for the passage?
A.Strong Sense of Smell May Be Linked to Longer Life
B.Old People Tend to Have a Poor Sense of Smell
C.A Number of Factors Result in Longer Life
D.Being Ill Means Losing the Sense of Smell

It's not just adults who have a thing or two to discuss with other people, babies too have their own social lives and enjoy group interaction, according to a world-first study.
The breakthrough study conducted by psychologist Professor Ben Bradley, at Charles Sturt University, could completely transform the way child-care centers are set up. In their study, the researchers examined groups of nine-month-old babies in new South Wales and Britain.
And they came across astonishing results—it was found that infants had “social brains” and focused not just on their mothers but on social 1ife in groups as well,
“They communicate with more than one baby at once，and show jealousy and generousness，”said Professor Bradley．
He added，“They develop their own meanings through group interaction，they notice if a group member is behaving differently and they take on roles，such as leaders and followers．”
“A baby who has a depressed mother tends to be withdrawn(内向的)，but put that same baby in a group of its peers(同龄人)and they behave and interact like any other baby．”
It was the first all-baby group study ever to be conducted．“Most studies of babies concentrate on the infant-mother relationship，assuming that is the single foundation for mental health．but babies are constantly involved with groups of people other than their mothers：fathers，siblings，grandparents and those taking care．Therefore。the ‘mother-baby approach’ needs to be combined with a‘ group approach’．”said Bradley．
Phoebe Christison ，a child-care worker at Camperdown Sunshine Bubs in Sydney’s inner west．said she often noticed what appeared．to be emotional attachments developed between toddlers．
She said，“Joel(10 months)and Isabella (11months)always like to hold hands when they sit in their high chairs and eat．And babies definitely show jealousy．They push and touch each other，and copy what the other is doing．”
1.A baby who has a depressed mother ____ ．
A．tends to be a follower
B．also enjoys group interaction
C．has poor social ability
D．pays more attention to its mother
2.What can be inferred from the result of this study?
A．Babies are affected by groups more than by their mothers．
B．There’s no need of child-care centers at a11．
C． Adults should include babies when having social activities．
D．The normal infant-mother bond alone isn’t enough for the good mental health for babies．
3.The underlined word “toddlers” in Para．8 can be replaced by_________
A．adults B．infants C．peers D．groups
4.The example given in the last paragraph proves that a baby________ .
A．is born to be friendly to other babies

A study has found that middle-aged and older adults who live in greener neighborhoods have a decreased risk of developing metabolic syndrome (代谢综合征) such as obesity, hypertension (高血压) and high blood sugar.
The study, published in Environmental Pollution, was conducted by the Barcelona Institute for Global Health (ISGlobal). It differed from previous studies on the health benefits of green spaces in that it examined all of the symptoms of metabolic syndrome together collectively rather than as individual components. Having metabolic syndrome increases a person’s risk for heart disease, stroke and type 2 diabetes, according to the National Heart, Lung, and Blood Institute.
The study from ISGlobal examined data from clinical examinations of over 6,000 British adults who were between 45 and 69 years old when the study began. The data was derived from four examinations participants went through between 1997 and 2013 that included blood analyses, blood pressure and measurements of weight. “These findings suggest that long-term exposure to green spaces can play an important role in preventing metabolic syndrome as a whole,” according to a press release published by ISGlobal.
The correlation between nearness to green spaces and better health could be associated with the expanded opportunities for physical recreation and lower exposure to air pollution, according to Carmen de Keijzer, ISGlobal researcher and principal author of the study.
Female subjects were more likely than males to exhibit the study’s association between living in greener neighborhoods and having fewer metabolic symptoms. “Women tend to spend more time in their residential neighborhood, which could explain this gender difference,” de Keijzer said. “We need greener cities if we want healthier cities.” de Keijzer added.
1.What do we know about the study from the first two paragraphs?
A.Young people were not included in the study.
B.Symptoms were examined one by one.
C.It was a joint effort of several institutes.
D.It was the first of its kind in decades.
2.What does the underlined word “derived” in Paragraph 3 mean?
A.Departed. B.Arrived.
C.Gained. D.Demanded.
3.Why do women have fewer metabolic symptoms?
A.Because they differ in gender.
B.Because they live in greener cities.
C.Because they live in healthier cities.
D.Because they stay more in where they live.
4.What can be a suitable title for the text?
A.Greener Neighborhoods, Fewer Metabolic Symptoms.
B.Women Having Fewer Metabolic Symptoms.
C.Metabolic Syndrome Increasing Heart Disease.
D.Living in Greener and Healthier Cities.

Chinese e-commerce websites fail to pay more attention to older consumers, says a news report.
There’s been a thought that younger consumers have been the driving force of online buying. That may not be the case. According to a statement from Alipay, the average expenditure (支出) of Alipay users born before the 1960s was 31,000 yuan in 2012, much higher than 14,000 yuan of those born after the 1980s. It shows that online shopping has become a key part of people’s daily consumption, for both young and old.
Besides shopping, people pay bills such as water bill, electricity bill, and credit card repayment online. The middle-aged and senior consumers are also participating in that consumption revolution.
Liu Chen, 56, said that his online expenditure in 2014 was over 50,000 yuan, about half of the total annual expenditure. He always pays his telephone bill online. Clothes, electrical appliances and kids’ snacks are the main items he purchases online.
Liu’s shopping strategy is to find something good online first, then go to shops to check it out, and finally buy it online because it is cheaper. As quality concerns him, Liu only buys items that come with a guarantee.
Stories such as those from Liu are representative of millions of middle-aged and older Chinese, which show the great potential of the aged in the Chinese consumption market. Yet, the market seems not to be valued as it should be.
Some Chinese e-commerce websites such as jd. com, dangdang. com and amazon. cn don’t have a category for goods for the elderly on their main pages. Alibaba’s platform does have one, but the goods in it are not as abundant as other categories. Moreover, Taobao’s category is not really designed for elders, but their children.
Despite the seeming lack of commitment to older consumers, the Chinese market for the elderly is clearly huge, and e-commerce websites should take great efforts to develop it.
1.The data in Paragraph 2 is used to prove that ________.
A. young people have learned to save money
B. older people are crazy about online shopping
C. young people are the driving force of online shopping
D. both the young and the old have contributed to online shopping
2.According to the passage, Liu Chen mainly spends money online on _______.
a. buying clothes
b. paying the telephone bill
c. paying the electricity bill
d. buying electrical appliances
A. a, b, c B. a, b, d C. b, c, d D. a, c, d
3. Liu Chen chooses online shopping mainly because of its ________.
A. low price B. convenience
C. great potential D. quality guarantee
4.Which is the best title of the passage?
A. Online shopping
B. Older consumers in e-commerce
C. Chinese e-commerce
D. Huge e-commerce market for the elderly

Elderly adults who regularly drink green tea may stay more agile (敏捷的) and independent than their peers over time, according to a Japanese study that covered thousands of people.
Green tea contains antioxidant chemicals (抗氧化化学物质) that may help stop the cell damage that can lead to disease.Researchers have been studying green tea’s effect on everything from cholesterol (胆固醇) to the risk of certain cancers，with mixed results so far.
They found those who drank the most green tea were the least likely to develop “functional disability”，or problems with daily activities or basic needs，such as dressing or bathing.
Specifically，almost 13 percent of adults who drank less than a cup of green tea per day became functionally disabled，compared with just over 7 percent of people who drank at least five cups a day.
The study did not prove that green tea alone kept people agile as they grew older.Green tea lovers generally had healthier diets，including more fish，vegetables and fruit，as well as more education，lower smoking rates，fewer heart attacks and strokes，and greater mental sharpness.They also tended to be more socially active and have more friends and family to rely on.But even with those factors accounted for，green tea itself was tied to a tower disability risk，the researchers said.
People who drank at least five cups a day were onethird less likely to develop disabilities than those who had less than a cup per day.Those people who averaged three or four cups a day had a 25 percent lower risk.
Although it’s not clear how green tea might offer a buffer (缓冲) against disabilities，lead researcher Yasutake Tomata did note that one recent study found green tea extracts (提取物) seem to increase leg muscle strength in older women.
While green tea and its extracts are considered safe in small amounts，they do contain caffeine and small amounts of vitamin K，which means it could affect drugs that prevent blood clotting (凝固)．
1.What does the underlined word “peers” mean in the first paragraph?
A．Fathers.
B．Brothers.
C．People of the same age.
D．People living in the same neighborhood.
2.What can be learned from the passage?
A．Antioxidant chemicals can lead to disease.
B．Those who often drink green tea can’t develop “functional disability”．
C．“Functional disability” is related to problems with daily activities or basic needs.
D．People who drink at least five cups a day are not likely to become functionally disabled.
3.What does the fifth paragraph mainly tell us?
A．How the study was proved.
B．Why green tea lovers can keep agile.
C．What healthier diets include.
D．How to lower the disability risk.
4.What has the researcher Yasutake Tomata discovered?

Earthquake rescue robots have experienced their final tests in Beijing. Their designers say that with these robots, rescue workers will be able to have more time to save more lives during an earthquake.
This robot looking like a helicopter（直升机）, is called the detector-bot . It's about 4 meters long, and it took about 4 years to develop the model. Its main functions（作用）are to collect information from the air, and send goods of up to 30kilos, to people stuck in an earthquake.
This robot has a high quality 360 degree panoramic camera. It can work day and night and will also be able to send the latest pictures from the quake area. Dr. Qi Juntong, Chinese Academy of Science, said, "Unlike other automatic machines, the most important feature of this robot is that it doesn't need a distant control. We just set the information of the earthquake-struck area on it, and then it takes off, and lands by itself. It flies as high as 3,000 meters, and as fast as 100 kilometers per hour. "
This robot has a different function --- it can change as the environment changes. Its main job is to search for any signs of life in places where human rescuers are unable to go.
As well as a detector（探测器）that finds victims（遇难者）and detects poisonous gas, a camera is placed in the 40 centimeter long robot, which can work in the dark.
Another use for the rescuers is the supply bot, with its 10-meter-long pipe. People who are caught in the ruins will be able to get supplies including oxygen and liquids.
Experts have said that the robots will enter production, and serve as part of the national earth- quake rescue team as soon as next year.
1.Which of the following statements about the robot is true according to the passage?.
A. It hasn't been put into production so far. B. It is a machine with a length of 10 meters.
C. It is a machine carried by a helicopter. D. It weighs about 30 kilos.
2.Dr. Qi Juntong thinks this robot is different from the others mainly because _____.
A. it has more functions
B. it has a more advanced camera
C. it can change as the environment changes
D. it can work by himself once given the information
3.The underlined word "which" in paragraph 6 refers to_____.
A. a camera B. a detector
C. a rescuer D. a doctor
4.What is the passage mainly about?
A. The appearance of the robot. B. An introduction to the robot.
C. The reason for making the robot. D. Some information about earthquakes.
