Chimps(黑猩猩) will cooperate in certain ways, like gathering in war parties to protect their territory. But beyond the minimum requirements as social beings, they have little instinct (本能) to help one another. Chimps in the wild seek food for themselves. Even chimp mothers regularly decline to share food with their children, who are able from a young age to gather their own food.

In the laboratory, chimps don't naturally share food either. If a chimp is put in a cage where he can pull in one plate of food for himself or, with no great effort, a plate that also provides food for a neighbor to the next cage, he will pull at random —he just doesn't care whether his neighbor gets fed or not. Chimps are truly selfish.

Human children, on the other hand are naturally corporative. From the earliest ages, they decide to help others, to share information and to participate in achieving common goals. The psychologist Michael Tomasello has studied this cooperativeness in a series of experiment with very young children. He finds that if babies aged 18 months see an unrelated adult with hands full trying to open a door, almost all will immediately try to help.

There are several reasons to believe that the urges to help, inform and share are not taught, but naturally possessed in young children. One is that these instincts appear at a very young age before most parents have started to train their children to behave socially. Another is that the helping behaviors are not improved if the children are rewarded. A third reason is that social intelligence develops in children before their general cognitive（认知的）skills, at least when compared with chimps. In tests conducted by Tomasello, the human children did no better than the chimps on the physical world tests but were considerably better at understanding the social world.

The core of what children's minds have and chimps' don't is what Tomasello calls shared intentionality. Part of this ability is that they can infer what others know or are thinking. But beyond that, even very young children want to be part of a shared purpose. They actively seek to be part of a “we”, a group that intends to work toward a shared goal.

    Beijing residents could be rewarded with up to 500,000 yuan if they can provide useful information on spies or related activities, according to a government policy that took effect on Monday.

    Under the policy, informants will be offered rewards ranging, from 10,000 yuan to 500,000 yuan, depending on how useful the information is, according to the policy issued by the National Security Bureau(安全局) of Beijing. Informants can pass information to authorities by calling a hotline, sending letters or visiting the bureau.

    Informants' privacy and information about spy-related messages will not be disclosed, while information providers can ask authorities for protection if they or their relatives are in danger due to the act of informing, according to the policy.

    However, informants will face punishments if they slander (诽谤) others on purpose or invent and spread false information, the policy states clearly.

    The bureau said that China is witnessing rapid increases in international exchanges and the number of people entering or exiting the country each year. "Meanwhile, overseas espionage agencies(间谍机构)and other unfriendly forces have also strengthened their disruptive(破坏的) activities in China, including political, economical and military information." it said.

    Some Chinese individuals have also betrayed the nation to benefit their private interests, which offers overseas espionage agencies opportunities, the bureau said, adding that Beijing is the primary location for such activities. Therefore, it's necessary to take new measures in anti-espionage investigation, and to encourage the participation of the general public.

    One of the most recent cases made public occurred in the eastern province of Jiangsu in January. Two residents in Lianyungang city, surnamed Zhang and Wan, called the national security authorities after they found a device with instructions in foreign languages while fishing in the Yellow Sea. The device was later found to be spying equipment made and used by overseas agencies to collect data, according to an official release.

    China has strengthened legislation(立法) on State security in recent years. Facing a more complex State security situation, in 2014, the Standing Committee of the National People's Congress adopted the Counterespionage Law.

    Jessica Tandy probably is best known for winning an Academy Award in 1989 for the movie Driving Miss Daisy. She was the oldest person to have won the award. But for many years, she had received praise for her great performances.

    Jessica Tandy was born in London in 1909. After her father died, her mother taught and took other jobs at night to make extra money to raise her, three children. Jessica's older brothers showed an interest in the theater and often put on shows at home. Jessica said later that she was terrible in all of them. But she said taking part in those plays as a child created a desire in her to be someone else.

    Jessica loved going to the theater. This love led her to attend an acting school in 1924. She performed in her first play called The Manderson Girls at 18. But few people watched this play. In 1932, she married the famous actor Jack Hawkins. Their wedding pictures were on the front page of many British newspapers. In the same year, critics in London recognized her great acting skill in her performance in the play Children in Uniform.

    In 1940, Jessica ended her first marriage and moved to the USA. In New York, she met actor Hume Cronyn. Two years later, they married and moved to Hollywood.

    Her turning point came in 1947 when she played the lead part in Tennessee Williams' play A Streetcar Named Desire. Tandy won the first of her four Tony awards for best actress in it. After that Hollywood producers began to choose her to be in the movie.

    Jessica Tandy said she hated seeing herself in the movies. She was surprised when she won the Academy Award for Driving Miss Daisy. She said that the wonderful part she had made up for her lack of experience in movies.

    From now, if all goes well, a high-tech spacecraft will land in the South Pole of the moon. There, it will drill 66 feet down into the surface(表面) and collect samples of the mantle(地幔样本) to bring back to the earth.

    But before it leaves, it will have a two-part time capsule(时光胶囊): a public part, full of the Earth's history, and a private part, full of digital(数码的) memory boxes created by individuals(个人). These memory boxes can hold digital files — records of family trees, videos or actual DNA in the form of human hair. Not everyone can have a digital memory box, though. The boxes are only delivered for the people who donate the money to the project.

    The project, called Lunar Mission One, has already raised more than half of its ￡600,000 goal since its launch(启动) just a few days ago. The founders thought that it would succeed because of the attraction of both exploring the moon surface and leaving a time capsule behind. The mission was a technical action, but it was also an emotional one, bringing the excitement of knowing that something humans built on the Earth reached somewhere else in space.

    Still, it does seem risky(冒险的) for a person to donate￡60 to keep a digital memory box for a project that won't come true until 2024. What if the project never takes off? What if the technology isn't good enough? What if those digital memory boxes break on the moon's surface? And how will anybody ever even know if that happens? Ian Crawford, a professor at Birkbeck College in London and scientific advisor to the mission, says it is not necessary to worry about these. The plan to leave a time capsule on the moon isn't really about physically leaving something on the moon — it's more an opportunity to encourage people's interest in space.

    When Mackenzie Foy got the call from film director Lasse Halls telling her that she'd landed the role of Clara in the newDisney film The Nutcracker and the Fоur Rеаlmѕ, she said "yes immediately. "I was just excited to go on a new adventure," Foy told the Evening Standard. Indeed, when many actors and actresses choose to appear in films simply for the fame and exposure, Foy, the17-year-old US actress, does it for the "adventure".

    It's true that every movie Foy has ever been in is an adventure. In The Twilight Saga: Breaking Dawn for example, the then 11-year-old Foy plays a half-human-half-vampire girl who has a superpower. In Interstellar, then 14, plays the daughter of a scientist who travels across the universe to try to find ways to save human beings from destruction. And now, in The Nutcracker and the Four Realms, which will be released in Chinese cinemas on November 2, Clara is going on yet another exciting journey. This time, she allows a doll that her parents give her as a Christmas gift into a strange world.

    Foy likes excitement in real life, too. In fact, she has a first-degree black belt in tae kwon do( MY y ilÏ)."I am dying to do an action movie," she told VanityFair. "I can do my own stunts." And not happy with simply being in front of the camera, Foy dreams of trying something new one day. I want to be a director once I finish high school," she told the Evening Standard. "I want to make films that will make people end up looking at the world in a different way, so that they will feel inspired and learn something new."

    Car washes are a common sight throughout Nigeria, but Madinat Aliyu's roadside business is very special: she is the only woman car-washer in the north of the country.

    "This job has caused me a lot of problems," said the 27-year-old, checking cars waiting to be cleaned in Gusau, the capital of Zamfara state.

    Aliyu took up her work two years ago, hoping to use the 7, 000 naira (£28) she earned every month to put her younger sisters and brothers through school following the death of their mother, the only one who made money to support the family. But her family begged her to stop doing this job, and she has received "judgment and warnings" from strangers too.

    "My grandmother cried for many days. Some people thought it was a joke to bring more customers (顾客). Others said if she is doing it for money, let's just give her money to stop bringing us shame," she said as she got water from a well by the roadside. "But I hate laziness or depending on somebody else."

    However, Aliyu has admirers. "Some customers only allow her to wash their cars," said her colleague (同事) Shamsudeen Mohammed. "I was trained to wash cars by men, and I can honestly tell you women are better to work under," he added.

    Recently another woman came to Aliyu to ask for advice on starting her own car wash. "Unfortunately her family discouraged her. I told her, if you listen to them, you will find yourself begging or marrying a man who is older than your grandfather," she said.

    Though she is considered a pariah (贱民) by many, Aliyu has no plans to stop her work. "I see men doing something and I think I can do it too."
