1 . Scientists have solved a puzzle about modern humans, after research showed that a famous skull of a human ancestor found in South Africa is a million years older than experts thought. This discovery has changed what we know of human history.
The skull, which scientists have named “Mrs Ples”, is from an ape-like human relative from a species called Australopithecus africanus (南方古猿). It was found near Johannesburg in 1947 and, based on evidence from its surroundings, was thought to be between 2. 1 and 2. 6 million years old. This puzzled scientists, because although Mrs Ples looks like a possible early ancestor of early humans, the first true humans had already evolved by the time she apparently lived. For this reason, scientists had decided that Australopithecus afarensis, a similar species from East Africa that lived about 3.5 million years ago, was our most likely ancestor instead.
To get a more accurate age for Mrs Ples, a team led by Professor Darryl Granger of Purdue University in Indiana, US, used a new method to date the sandy rocks where the skull lay. They measured the amount of certain chemicals in rocks, which form at a steady rate when they are exposed to cosmic rays (宇宙射线) on Earth’s surface. Once rocks are buried, these chemicals stop forming and slowly disappear;the surviving amount reveals how much time has passed since the rock (or bones) were on the surface.
The new study shows that Mrs Ples and other australopithecine bones nearby are between 3.4 and 3.7 million years old. This means they lived at the same time as their East African relatives, so that either group could have given rise to modern humans. However, team member Dr Laurent Bruxelles pointed out that over millions of years, at only 2,500 miles away, these groups had plenty of time to travel and to breed with each other. In other words, the groups could quite easily have met, had children together and both been part of the history of modern humans.

4 . A lifetime of active exercise will let you keep the body of a 20-year-old well into your 70s, scientists have found.
The physical decline (衰退) thought to be an unavoidable part of ageing is actually the result of not exercising enough, according to the research, which found that regular cyclists kept the muscles, lungs, and even the immune system (免疫系统) of people years younger. Besides, many serious health problems could be prevented if people became more active, researchers insist.
Janet Lord, a leading researcher, said, “Our findings prove the false belief that ageing automatically(自动地) makes us weaker. We now have strong evidence that encouraging people to do regular exercise throughout their lives can solve the problem that we are living longer but not healthier.”
She looked at 125 cyclists aged 55 to 79 who had been exercising regularly for 25 years and compared them with 75 ordinary people of a similar age and 55 people aged 20 to 36. On a series of physical measures, the cyclists showed no difference from people much younger in their immune systems and making T cells.
Now Professor Lord aims to discover how much exercise people need to do to stay young. “You needn’t work out a lot. It may be intensity (强度) that helps—like going up and down the stairs ten times a day.”
While there is no magic method of staying mentally and physically fit in later life, the benefits of keeping active can never be ignored, whatever your age or state of health.

6 . You may have heard the term self-awareness, but what is it and why does it matter?
Being self-aware can influence how you feel in your job and in your personal life. Daniel Goleman takes that connection much further, saying self-awareness is the key to success. He describes self-awareness as “knowing one’s internal (内在的)states, preference and resources”, and then monitoring that “inner world” information as it comes up. If you can be as aware of your feelings and thoughts, you’ll be better able to deal with new situations. Because you know yourself better, you’ll be more accepting of yourself, your thoughts and your feelings, Goleman says.
But self-awareness doesn’t stop at how you see yourself. It’s also understanding and acknowledging how others see you. Tasha Eurich, an organizational psychologist, explains that self-awareness has two parts — internal and external (外部的). Internal self-awareness means we can clearly see our own values, thoughts, passions and feelings. External self-awareness is clearly seeing how others see us. People who are externally self-aware tend to be better leaders.
So how do you know if you’re self-aware or not? Eurich developed a short online quiz to help. You’re not the only one who has to take it. Someone who knows you well also has to answer questions about you.
In a recent TED Talk, Eurich refers to self-awareness unicorns. This group makes up only a small part of all the people she has studied. These are people who not only believe they are self-aware, but other people who know them would agree. Additionally, these unicorns would say they have improved their self-awareness in their lives and again, those who know them well would agree.
Thankfully, anyone can become more self-aware, as long as they’re willing to devote some time and effort to the cause.

7 . One day, I was sitting in a local coffee shop, and staring at this man in a wheelchair. He could move his head and parts of his fingers but nothing else. He had a servant who cut up his food and placed it on a special mechanically powered fork that he would use to eat.
He saw me staring at him and invited me to join him at his table. His name was Stephen. For several hours we sat at that table and we got to know each other on a deeply personal level. I had never known a man who was more radiant (容光焕发), more energizing to talk and get to know than Stephen.
Stephen used to be a very successful businessman in Denver. He was in the natural gas business. Thirteen years before, when he was forty, he was waiting for news of a natural gas discovery to occur any moment.
He said, “I had so much nervous energy. I saw the storm clouds gathering, and I decided to clean out the gutters (檐沟)rather than sitting around waiting for this gas well to come in.”
He climbed up the ladder to clear the piles of pine needles on the roof. As he backed up, he accidentally fell off the roof. He landed on his back. He was paralyzed (瘫痪) for the rest of his life, except for his head and his hand.
I asked him, “How do you do it all? How do you suddenly stop hiking, fishing, and running marathons?”
He said, “There are three things you have to do when something like this happens. The first thing you have to do is adjust. The second thing you do is adjust. And the third thing you do is adjust.”
He said, “By adjusting to your abilities, Bill, you have to change your self-expectations. If you can’t be a physical athlete any longer, then perhaps you can be a spiritual athlete.” He was.

9 . TOKYO - A powerful typhoon is heading northeast to Japan’s main island of Honshu on Sunday after sweeping parts of the country’s southern islands with heavy rains and winds that caused flooding and some light injuries.
Typhoon Tapah was passing near Nagasaki in southern Japan on Sunday afternoon, after hitting other parts of southern Japan, including Okinawa, the two former days. Okinawa government had made an evacuation advisory(疏散警告) to nearly 334,000 people.
Japan’s Meteorological Agency said the storm was moving northeast at a speed of 30 kilometers per hour, with the strongest winds of 162 km/h. It would travel through the sea between Japan and the Korean Peninsula before moving toward northern Japan on Monday, when it is expected to be weak and slow the pace, the agency said.
More than 400 flights were stopped because of the storm, according to NHK. The typhoon hit Okinawa on Friday and Saturday and left 21 people with not serious injuries. The storm upset air and train travel in this area during what is a three-day weekend.
In Nobeoka City in Miyazaki, a strong dangerous wind believed to have been triggered by the typhoon damaged at least one house and injured two people a little, according to the Fire and Disaster Management Agency. The coming typhoon also caused fears in parts of Chiba, near Tokyo, which was hit hard by another typhoon earlier this month. That typhoon damaged many houses and electrical power stations, causing widespread electricity’s being cut off in the area.

10 . This holiday season, it’s expected that more than 45 million people will get on airplanes by the time the year ends. With that many people on the move, delays are not able to be avoided, and with them come upset and unhappy passengers.
That space between happy passengers and unhappy passengers is where Fred Taylor Jr. worked for 15 years in customer relations with Southwest Airlines.
“My job was to say sorry by sending letters to customers whose flights have been put off or stopped,” the 47-year-old said. His daughter Olivia tells her friends he is “the Sorry Man.”
I don’t think I can explain reasonably to you for the delays that happened with your December 1st flight from ...
“For me, I’m used to saying ‘I’m sorry’ ,” Fred told his wife, Julie. “It’s been a way of life.”
Of course, you have to know your audience, he explained.
“You know, there are some travelers who may get upset pretty quick,” he said. “If an engine shuts down because parts of the fan blade(风机叶片) break and you can see plumes of(一缕缕) fire, there will be fears, worries, regrets or other emotions. My job was to calm them down: Hey, this wasn’t as serious as what it may have seemed like.”
And I know whatever I say now cannot change the poor service you were given that tiring day ...
But Fred has other ways to turn sadness into joy.
“When my dad died and you wrote a eulogy(悼词), I can remember hearing the people behind me crying. And then you started with the funny stories, and I could hear the people behind me laughing. It was just perfect. You put people at ease.” Julie said.
“So, you’re more than just ‘the Sorry Man,’ ”she said with a laugh.

B.To tell us that the world is becoming smaller than before. |
C.To show us the wide use of airplane in today’s world. |
D.To show that people are always upset about their flights. |
A.Because she is tired of her father. |
B.Because she wants to make fun of her father. |
C.Because her father’s job is to say sorry by sending letters. |
D.Because her father often makes mistakes. |
A.Julie thinks Fred is a wrong man. |
B.Julie thinks Fred is just “the Sorry Man”. |
C.Julie looks down upon Fred. |
D.Julie praises what Fred has done. |
