Before I studied psychology, I used to think that people would laugh when funny things occurred. While I was right about that, I discovered there are lots of other psychological factors that make people laugh other than the funny part of a joke. When someone laughs at a joke, there will usually bemore than one reason that makes him laugh—and the more reasons there are, the more powerful the joke will be.

    I was attending a stand-up comedy show in Egypt, and when the man started to make fun of pedestrians crossing streets, everyone laughed their hearts out. The main reason those people strongly laughed was that almost allof them felt angry towards pedestrians who crossed streets carelessly. The joke wasn't only funny, it also made the audience feel that they were right about being angry at those pedestrians. That is, people were laughing both because ofthe funny joke and because of the happiness experienced as a result of the psychological support they got.

    The better a joke makes a person feel, and the more it includes other psychological factors, the more the person will like it. For example, if you envy one of your friends, and someone tells a joke that is funny and, at the same time, makes your friend seem stupid, then you will probably laugh atit louder than if you weren't jealous of him.

    In short, we don't laugh only when we hear something funny; we also laugh when we experience some kind of happiness that results from the other psychological factors involved in the joke. I strongly discourage making fun of anyone or belittling someone to make someone else laugh. All Iwant to explain is that if your joke supports a person's emotions, he will certainly like it a lot.

    Two men, Alan and Henry, both seriously ill, shared a hospital room. Alan was allowed to sit up in his bed and his bed was next to the room's only window. Henry had to spend all his time flat on his back.

    The men talked for hours, of their wives, families, their homes and their jobs. And every afternoon when Alan, in the bed next to the window, could sit up, he would pass the time by describing to his roommate all the things he could see. Ducks and swans played on the water while children sailed their model boats. Lovers walked arm in arm among flowers. Trees and skyline could be seen in the distance. As he described all this, Henry, on the other side of the room, would close his eyes and imagine the scene.

    One warm afternoon Alan described a parade (游行) passing by. Although Henry could not hear the band, he could see it in his mind. Unexpectedly, an alien thought entered his head: why should he have all the pleasure of seeing everything while I never got to see anything? It doesn't seem fair. Henry felt ashamed at first. But as the days passed and he missed seeing more sights, his envy grew and soon let him down. He began to find himself unable to sleep. He should be by that window — and that thought now controlled his life.

    Late one night, as he lay staring at the ceiling, Alan began to cough. He was choking. Henry watched in the dim room as the struggling man tried hard to reach for the button to call for help. Listening from across the room, he never moved, never pushed his own button which would have brought the nurse running. In less than five minutes, the coughing and choking stopped, along with the sound of breathing. Now, there was only silence — deathly silence.

    As soon as it seemed appropriate, Henry asked if he could be moved next to the window. The nurse was happy to make the switch and after making sure he was comfortable, she left him alone. Slowly, painfully, he struggled to take his first look. Finally, he would have the joy of seeing it all himself. He looked out, but faced a blank wall.

    Slowly but surely  we're moving closer and closer to 5G world. From smart-home security to self-driving cars, all the internet-connected devices in your life will be able to talk to each other at lightning-fast speeds with reduced delay, Objectively speaking, the fastest 4G download speeds in the U. S. top out at an average of 19.42 Mbps. But by comparison 5G promises gigabit (千兆) speeds.

    “5G is one of those signs, along with artificial intelligence, of this coming data age,” said Steve Koenig, senior director of market research for the Consumer Technology Association. “The self-driving vehicle is a great emblem of this data age, and that is to say, it is a sign of time, because with one single task, driving, you have massive amounts of data coming from the vehicle itself, and a variety of sensors are collecting a lot of information to model its environment as it moves. It's pulling in data from other vehicles about road conditions down the lane. It could be weather information, but also connected infrastructure (基础设施) construction. There's lots of data behind that task, which is why we need high speed.

    Augmented reality glasses and virtual headset haven't yet broken the mainstream, but tech companies are joyfully betting that these devices will eventually replace our smartphones. With 5G, that could actually happen. This is notable because companies such as Apple are reportedly developing AR glasses to assist — or perhaps even replace — smartphones.

    Ericsson stated at February's Mobile World Congress how smart glasses could become faster and lighter with a 5G connection, because instead of being weighed down with components, the glasses could rely on hardware for processing power.

    But don't get too excited. There's still a lot of work to be done in the meantime, including various trials to make sure the radios play nicely with hardware and infrastructure construction so 5G isn't concentrated only in big cities.

A new book called "Battle Hymn of the Tiger Mother" by Amy Chua has caused a debate (争论) about cultural differences in parenting. Amy Chua is a teacher in an American university and both of her parents are Chinese. In the book, Ms. Chua writes about how she taught her daughters. She told NBC television that she had a clear list of what her daughters were not allowed to do, such as having a play date, watching TV or playing computer games and getting any grade less than an A.

Many people are against Amy Chua's parenting style (风格), even her husband, who is American. They say it is rude and unfair to children. But she says her parents raised her and her three sisters in that way.

Ms. Chua says after her younger daughter shouted "I hate my life! I hate you!" she decided to retreat because she was afraid of losing her daughter. But she also says American parents often have low expectations of their children's abilities.

"The debate is about what it means to be a successful parent and what it means to be a successful child," said Stacy DeBroff, who has written four books on parenting. She says Amy Chua's parenting style is not limited to Chinese families. It is a tradi-tional way of parenting among immigrants (移民). They hope to get a better future for their children.

She also sees a risk (风险). When children have no time to be social or to develop their own interests, they might not develop other skills that they need to succeed in life. DeBroff advises parents to develop their own style of parenting and not just repeat the way they were raised.

Elephants might be the most well－known and well－loved animal in African wildlife. But conservation (保护) of the African elephant faces special difficulties. While the elephant population is half of what it was 40 years ago, some areas of Africa have more elephants than populated areas can support. That's why AWF scientists are studying elephant behavior, protecting habitats and finding ways for humans to live peacefully with elephants in Africa.

Years ago, overhunting and the ivory trade were the biggest threats to elephants' survival. Luckily, ivory bans (禁令), hunting rules and protected areas protect elephants from these dangers today.

The 21st century brings a different challenge to elephant conservation—land－use. Elephants walk across borders and outside parks and other protected areas. So they often destroy crops, causing conflicts (冲突) between local farmers and these big animals.

Successful conservation strategies (策略) must allow elephants to walk freely in their natural habitats while reducing conflicts between elephants and local people.

AWF researchers are searching for a way to give both elephants and people the space they need. The AWF is collecting information on elephant habitats and behavior. The information they gather will help to develop the widest possible space for elephants.

The AWF is helping elephants by protecting their habitats. And they also work with local farmers to improve their life in order to encourage them to protect rather than destroy elephants.
