    Dr Wiseman started “the laugh lab” project in September 2001. It is the largest study of humour. Participants（This is a subject that has long attracted psychologists and philosophers. Most of the time, people are not completely honest. We do things that society expects us to and say things that help us get what we want. But laughing cannot be controlled. When we laugh, we tell the truth about ourselves. By December 2001 over 10, 000 jokes had been submitted. This gave the scientists enough evidence to make early conclusions. It seems that men and women do have different senses of humour, for instance.

    Dr. Wiseman. “Males use humour to appear superior to others, while women are more skilled in languages and prefer word play. ”

    Researchers also found that there really is such a thing as a national sense of humour. The British enjoy what is usually called “toilet humour”. But the French like their jokes short and sharp: “You're a high priced lawyer. Will you answer two questions for $500?” “Yes. What's the second question?”

    The Germans are famous for not having a sense of humour. But the survey found that German participants were more likely to find submitted jokes funny than any other nationality.

     Perhaps that proves the point. Is this joke funny? I don't know, but let's say yes, just to be safe. Dr Wiseman and his workmates also submitted jokes created by computer. But none of those who took part in the survey found any of them amusing. Perhaps this is relief. Computers already seem like they can do everything. At least they should leave the funny stuff to us.

    Sumeja Tulic had moved from London to New York nine months ago to attend journalism school. Yet her time in New York met with a season of never-ending ugliness in politics and acts of terrorism(恐怖主义) around the world. “One day you laugh, and then you're angry,” said Tulic. As she walked toward the subway station, she thought, “I want to see something nice. Enough of this craziness.”

    At the City Hall station, she saw a man resting against a pillar(柱子), the way anyone might, waiting for the train. The stillness was interrupted(打断) by an announcement that the next train was two stations away. Then Tulic saw the man at the pillar falling forward onto the tracks.

    The man who had fallen was not moving. In what seemed like an instant, three men jumped down to help.

    I don't know where these men got the intelligence and the quickness," Tulic said. "The man who fell was about six feet tall and quite heavy. He was kind of stuck in the tracks. It was terrifying to know that the train was coming. Will it stop? Will they succeed in pulling him out?"

    On the tracks, the unconscious(失去知觉的) man was put into a sitting position by the three men, who then lifted him from below to others who lifted from above and rolled him onto the platform. Then the rescuers were themselves rescued, pulled back to safety by helping hands. As soon as they were all clear, the train pulled in. People getting off the train walked around this unconscious man.

    Two of the men who had jumped onto the platform were holding his hands. “They were saying, ‘You're going to be fine,'” Tulic said. “This was an additional layer of goodness.”

    Doctors arrived, and the man was taken to a local hospital with serious but non-life-threatening injuries.

    “That is the greatest thing,” Tulic said. “The infrastructure(基础) in this city of millions is the people themselves providing, being there for others, without even knowing the person, who he is. It was beautiful to see.”

    While Black Friday and Cyber Monday help start the holiday shopping season, Giving Tuesday, which will be observed on November 28, attempts to inspire the season of giving. Now in its sixth year, the charitable(慈善的)day uses the power of social media to encourage organizations and individuals to donate funds or resources to worthy causes. Its mission is to bring positive change to communities through giving.

    Though devoting just one day to a worthy cause may not seem much, Giving Tuesday makes a surprisingly significant impact. In 2015,ORGANIZE,an online organ donor program asked people to “Give with your Heart”,by becoming registered donors. Thousands of Americans listen to the cry for help, resulting in one of the largest digital donor drives in US history.

    That same year, the Cleveland Library and the Pratt Library in Baltimore competed to see who could encourage more donations. While the Pratt Library won with a $41,000 acquisition, the Cleveland Library was able to raise a fairly large amount for its programs as well. In 2016, the University of Michigan encouraged students and friends to donate to hourly challenges. They raised an amazing $5.5 million! The university hopes to recreate the magic this year, with a virtual celebration to mark the institution's 200th anniversary.

    Giving Tuesday is not just a US phenomenon, but a global movement. In 2016, 98 countries participated in the event, raising $177 million, a 44% increase over 2015, when 71 nations collected $116.7 million. These numbers can only increase as the day gains further recognition.

    Though donating funds is a great way to help, there are numerous other ways to support your local community. You can give back by volunteering at a nearby nonprofit or food bank. Social media experts can do their share by spreading the information and inspiring their colleagues to get involved. Another great way to celebrate Giving Tuesday is by helping those closest to you, whether that's assisting a family member with chores or helping a neighbor with yard work.

    Dolphins, African gray parrots and some other animals understand the idea of “zero,” but researchers were surprised to find that honeybees also comprehend this abstract concept, considering the insects' tiny brains, according to a new study. Honeybees have fewer than one million neurons (神经元), compared with the 86 billion neurons in humans—and yet, they grasp a concept that humans, by some measures, don't start to understand before preschool.

    The researchers set up two cards, each of which had a set of symbols on them, like triangles or circles. Then, they trained a group of the bees to fly to the card with the lower number of symbols. The bees quickly learned what the humans wanted them to do to get their delicious, sweet rewards. The trained bees were then shown a card that was empty and one that had symbols on it. There is no need for the bees to be trained to fly more often to the empty card—thus showing that they understood that “zero” was a number less than the others.

    Although they flew more often to an empty card than to one that had one symbol on it, it became easier for them to distinguish when the symbols on the card increased in number. For example, they more often flew to the zero when the other card had four symbols than when it had one.

    Perhaps these findings will explain the brain mechanism (机制) behind what allows us to understand the concept of “nothing,” Adrian Dyer, a researcher said. This understanding, in turn, could help in the development of artificial intelligence (AI) that also understands this concept. “If bees can understand 'zero' with a brain of less than a million neurons, it suggests there are simple, efficient ways to teach AI new tricks,” Dyer said in the statement.

    One cold morning in winter, I went alone to a hillside to do some hunting. I sat there waiting for about an hour. Suddenly, a big beautiful deer appeared less than 20 feet away from me. There was no cover near him. Surely I could shoot him.

    To my surprise, he came toward me! He was curious, I suppose, or maybe he was stupid. For this was not a young deer, but a fully grown-up one. He must have known about men and their guns. But this deer came closer, and I still waited. His big eyes never moved away from my face. His wonderful head with a set of antlers (鹿角) was clearly in sight.

    I was getting a bit nervous as he walked closer. A big deer can do a lot of damage. Well, he walked right up to where I was sitting. Then he stopped and looked at me.

What happened next was hard to believe. But it all seemed quite natural. I held out my hands and touched his head right between the antlers. And he liked it. The big, wild, beautiful deer bent his head.

    I touched his head and body. His nose touched my shoulder. I fed him with my last sandwich.

    Well, he finally went his way, down the hill. Shoot him? Not me. You wouldn't, either. Not after that. I just watched him go, a strong deer carrying a proud head.

    I picked up my gun, and started walking back. Suddenly, I heard two shots, one after another. If you have hunted much, you will know what two shots mean. They mean a kill. I had forgotten that there were other hunters around.

    You will now understand why I gave up hunting from that day on.
