Older adults who sleep six hours or fewer a night may have elevated risk for dementia(痴呆症) and other cognitive (认知的) issues, a new study finds.
Researchers at Stanford University measured seniors' (ages 65 to 85) dementia risk and cognitive abilities, finding higher risk in those patients who regularly slept six or fewer hours compared to those who slept seven or eight hours. Those seniors who slept nine or more hours also had lower cognitive functions and other health issues, but the researchers didn't find the same high dementia risk in this group.
The findings demonstrate how important it is for adults to maintain a healthy sleep cycle, especially as they get older.
As adults age, it's common for their sleep patterns to change or becomedisrupted— leading to longer, shorter, or more irregular sleep. This disruption may be linked to Alzheimer's and other forms of dementia, impacting seniors' ability to remember information, problem-solve, and go through everyday behaviors. Sleep disruption can also be caused by or heighten depression, cardiovascular disease（冠心病）, and other conditions.
A recommended sleep time for seniors is seven to eight hours, the researchers said. Six or fewer hours corresponded to short sleep, while nine or more hours corresponded to long sleep.
The Stanford researchers measured levels of beta amyloid, a protein in the brain that is typically found in high levels when a patient develops Alzheimer's. In addition, the researchers used several tests for memory, attention, spatial skills, and executive function to identify patients' cognitive abilities. Those patients sleeping for six hours or fewer a night were more likely to develop dementia, the researchers found. The low-sleep patients had higher levels of beta amyloid.
The Stanford researchers found that patients with lower sleep also performed worse on memory tests, while those with higher sleep (more hours) performed worse on executive function tests，which measure the brain's ability to switch between different tasks.
―The main takeaway is that it is important to maintain healthy sleep late in life, Winer told CNN.

A Chinese space mining company has designed a robot that can capture waste material left behind by spacecraft in outer space with a big net.
The state-run Xinhua news agency recently reported that the robot launched on the government's Long March 6 rocket along with several satellites. The robot will also investigate deep space to observe small objects in the universe. The 30-kilogram robot, called NEO-01 , was developed by Origin Space. Pounded in 2019 and based in the southern Chinese tech hub(技术中心)Shenzhen, Origin Space has been devoted to exploring and using space resources, according to the company. The company says the robot will lead the way for future technologies capable of mining on asteroids(小行星).
The world's first asteroid mining company, Planetary Resources, was established in 2009. Since then, more than 12 businesses around the world have entered the industry, including 3D Systems of the United States and Japan's Astroscale. Astroscale's technology uses magnets (磁铁)to gather up space waste. But a report on the Origin Space website says NEO-01 will use a net to capture waste and then bum it. Thousands of satellites have been launched worldwide. As they are used too long, many end up as waste and put other operating satellites at risk.
Su Meng is the founder of Origin Space. He said the company plans to launch many space telescopes and more spacecraft to begin the first for-profit mining of asteroids by 2045. Su added that NEO-01 will serve as a prototype (雏形)of future space mining robots, which can use rich mineral resources on asteroids to support the development of the space industry.
The Xinhua news agency reported that China was increasing efforts to land a spacecraft on a near-Earth asteroid to collectmaterials. China is also speeding up a plan to build a defense system against near-Earth asteroids. The country aims to follow Russia and the United States in becoming a major space power by 2030.
4. Which of the following can correctly describe NEO-01?
A. It weighs 60 kilograms.
B. It was created by Planetary Resources.
C. It will be burnt after finishing its mission.
D. It is mainly used to catch space waste.
5. What can be inferred from the text?
A. China will be the most powerful in space by 2030.
B. Origin Space will open more mines on asteroids.
C. It is those useless satellites that make space waste.
D. The robot will look into deep space for more waste.
6. What does Su Meng think of NEO-01 ?
A. It is promising and rewarding.
B. It has benefited the space industry.
C. It's a long way to produce it.
D. It'll help make money for the company.
7. What can be the best title for the text?
A. NEO-01 , A Smart Robot Used in Space
B. A Chinese Robot Can Catch Space Waste
C. A New Robot Makes China a SpacePower
D. NEO-01 , the Pioneer of Future Space Robots

In 1990, Hal Donaldson was 23 years old, fresh out of college and found himself in Calcutta, India, where he was asked to interview Mother Teresa.
Donaldson says about the great woman famed for feeding the hungry, “She wasn't wearing shoes and her ankles were swollen. She sat down with me and was very polite.” After the interview, Mother Teresa asked him, “What are you doing to help the poor?” Donaldson admitted that he was young and wasn't focused on helping others. With a smile on her face, Mother Teresa said, “Everyone can do something.”
Those words deeply struck Donaldson and forced him to face some hard truths about himself.
Hal Donaldson grew up in the San Francisco Bay area. When he was 12 years old, his parents were hit by a
drunk driver; his father died, and his mother was seriously injured. To make ends meet, they went on welfare. Donaldson says, “I had holes in my shoes and clothes. When you're teased at school for that, you just want to escape.”
He managed to do just that. Donaldson got into college and turned his focus to making money for himself He says, “I was just trying to find my way out of insignificance. However, it's easy to overlook others along the way. I was the guy that would see a homeless person and cross the street, so I didn'thave to confront (面对) him. My focus was on climbing to the top instead of helping those trying to climb with me.”
Donaldson returned home from India with a different thought. He traveled to eight cities in America and stayed on the streets and listened tostories of the homeless. “My heart broke,” he says. “I knew I could no longer just live for myself.”
Inspired by Mother Teresa's words and the stories he'd heard across America. Donaldson loaded a pick-up truck with $300 worth of groceries and handed them out to anyone who needed help. In 1994, Donaldson created the nonprofit organization, Convoy for Hope, which works with communities across America and around the world. Their work focuses on feeding children, women's empowerment, helping farmers and disaster services.

Older adults with a better sense of smell may live longer than thosewho have a poor sense of smell, a new study suggests. The study was a project of researchers in theUnited Statesthat 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 withMichiganStateUniversityinEast 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 goesbeyond dementia or other neurodegenerative(神经变性的) diseases. These often signal the beginning of a weakening of the mind or body.
12. 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.
13. What was the situation like at the beginning of the study?
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.
14. 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.
15. 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

Patience is of great importance in our daily life. Once I waited a bus to come at a stop. 30 minutes past, but no bus came. Both upset and annoyed, I decided to walk on feet. But no sooner had I left when the bus arrived. I thought if I had waited for one more minute, I would have caught it. If I chose to take a next bus, I would have to wait for other 30 minutes. Only then do I realize my problem. Being impatient will possible waste all the effort that we have put it in. Now whenever I am close to lose my patience, I’ll think of this experience.
