Disney has picked Chinese actor Liu Yifei to play Mulan in an upcoming film, following accusations against Hollywood of ‘whitewashing'.

    Several Hollywood films have faced criticism in recent months for featuring white actors in Asian roles. Recent films accused of whitewashing include the Hollywood remake of Japanese anime Ghost in the Shell, which had Scarlett Johansson in the main role which was originally Japanese, and Chinese epic The Great Wall which starred Matt Damon as its lead character. Earlier this year, British actor Ed Skrein who was cast as an Asian character in the upcoming Hellboy remake pulled out of the film so that the role could be “cast appropriately”. It then went to Korean-American actor Daniel Dae Kim.

    The live-action adaptation of the 1998 cartoon movie will tell the tale of the well-known Chinese heroine Hua Mulan. Mulan pretended to be a man to fight in the army to spare her weak father from being forced into the army.

    The film has been under careful examination since it was announced that Disney intended to remake Mulan. An online campaign calling for an Asian actress in the role attracted more than 100,000 signatures before it was shut on Thursday.

    Liu, nicknamed “Fairy Sister” for her delicate looks and previous roles in fantasy dramas, is well-known as an actress, model and singer in China. The 30-year-old is said to be fluent in English, having grown up partly in New York. The Hollywood Reporter said she was picked out of nearly 1,000 candidates for the film.

Disney's announcement on its blog about Liu's casting was met with delight on Twitter as well as on Sina Weibo, China's microblogging network. Many online celebrated it as a win for diversity in Disney films. Chinese-American actress Ming-Na Wen, who voiced Mulan in the original animated movie, also gave her stamp of approval. Chinese netizens congratulated Liu, with many praising Disney's choice. One commenter said, “Needs to know martial arts, can also speak English, has star quality - it definitely should be Liu Yifei.”

    I always wondered how people would react if I tried to approach a total stranger for help in a busy place like a street corner or in a noisy mall. I have always hurried past a stranger who tried to catch my attention in a busy place or when I am rushing around.

    Yesterday, I was in a busy shopping mall buying a large piece of luggage because I just had the time to do it after many days of planning. After the purchase in one of the large shops, I picked up my phone from my pocket to call my driver waiting in the parking lot but my phone was dead.

    I then requested the shop assistant who had just sold me the luggage to ring the number of my driver for me and she replied that it was the shop policy that they cannot use mobile phones while working in the shop.

    I got out of the shop onto the busy street in front and approached a young mother with her two kids to make a request. As soon as I said “Excuse me, madam”, she grabbed both her kids and ran. I felt like a kidnapper.

    I stood there, wondering how many times I had reacted to strangers like the young mum. I stood there in the busy street with people rushing by, looking at their faces to see if there was a sign of kindness on their faces.

    I saw a man pretty shabbily dressed. He seemed to have noticed me and I just stopped him expecting him to rush past. My request escaped the lips. He immediately called the number of my driver and waited till my car came to be sure I was picked up, and he turned around before I could thank him adequately and was gone. I was surprised by his kindness and hope I will do likewise (同样地) to strangers who try to catch my attention from now on.

    When Chris moved in across the hall from Norma Cook four years ago in a Los Angeles-area apartment complex, the 31-year-old actor waved to his 85-year-old neighbor for a few weeks before finally knocking on her door and introducing himself. “The day I entered her apartment and spoke with her face to face was the day my life was changed forever,” Chris said.

    He learned that Cook had no family living in California and that she suffered from a long list of illnesses, including leukemia (白血病). The pair quickly became close friends, as Chris took her to doctor's appointments, cooked with her and they ran errands (差事) together. He shared their adventures on social media. But recently, Cook's health declined and she was in and out of the hospital several times. She once spent weeks in the hospital fighting pneumonia and breathing issues.  Eventually Cook was told by one of her doctors that she could no longer live at home unless she had 24-hour care. Because Cook had no money saved to pay her health care costs, Chris started a Go Fund Me account to help cover her bills.

    But caretakers are expensive and Cook quickly ran out of the $34,445 they raised. Knowing her days at home were limited, Chris invited Cook to move in with him to save money.“ She loves it! I do most of my work at home so I am here most of the time to care for her. It only made sense to both of us.” Chris wrote. “She is my adopted grandmother after all and I am her grandson she never had.”

    “Cook still has weekly hospice health care visits and regular visits from caregivers, so any funds raised cover those expenses,” he wrote. Though doctors say Cook's days are very limited, the pair are enjoying spending time together drinking champagne and snuggling with her cat, Hermes, who also made a move.

    “She does not want to change,” Chris told Today. “My apartment was the only place she would have moved. She has strong opinions about where she wants to carry out the rest of her days, and she wants to stay here.” Chris says he feels like the relationship was fate. “Moving her in....it feels as though it was meant to be all along, ” he said. “It's really fulfilling to be there for her.”

    According to official government figures, there are more than twice as many kangaroos as people in Australia, and many Australians consider them pests(有害动物). Landholding farmers say that the country's estimated 50 million kangaroos damage their crops and compete with livestock for scarce resources. Australia's insurance industry says that kangaroos are involved in more than 80 percent of the 20,000-plus vehicle-animal collisions reported each year. In the country's underpopulated region, the common belief is that kangaroo numbers have swollen to “plague proportions."

    In the absence of traditional hunters, the thinking goes, killing kangaroos is critical to balancing the ecology and boosting the rural economy. A government-sanctioned(政府认可的) industry, based on the commercial harvest of kangaroo meat and hides, exported $29 million in products in 2017 and supports about 4,000 jobs. Today meat, hides, and leather from kangaroos have been exported to 56 countries. Global brands such as Nike, Puma, and Adidas buy strong, supple “k-leather" to make athletic gear. And kangaroo meat is finding its way into more and more grocery stores.

    Advocates point out that low-fat, high-protein kangaroo meat comes from an animal more environmentally friendly than greenhouse gas-emitting sheep and cattle. John Kelly, former executive director of the Kangaroo Industry Association of Australia, says, “Harvesting our food and fibers from animals adapted to Australia's fragile rangelands is extremely wise and sustainable. Many ecologists will tell you that there is no more humane way of producing red meat."

    Opponents(反对者) of the industry call the killing inhumane, unsustainable, and unnecessary. Population estimates are highly debatable, they say, but “plague proportions" are biologically implausible. Little kangaroos grow slowly, and many die, so kangaroo populations can expand by only 10 to 15 percent a year, and then only under the best of circumstances. Dwayne Bannon-Harrison, a member of the Yuin people of New South Wales, says the idea that kangaroos are destroying the country is laughable. “They've been walking this land a lot longer than people have," he says. “How could something that's been here for thousands of years be 'destroying' the country? I don't understand the logic in that."

    Can Australians' conflicting attitudes toward kangaroos be reconciled(和解)? George Wilson says that if kangaroos were privately owned, then graziers(放牧人)—working independently or through wildlife conservancies—would protect the animals, treating them as possessions. They could feed them, lease them, breed them and charge hunter a fee for access. “If you want to conserve something," Wilson says, “you have to give it a value. Animals that are considered pests don't have value."

    Privatization could also help reduce grazing pressures. If kangaroos were more valuable than cattle or sheep, farmers would keep less live-stock, which could be good for the environment. Under this scheme, landholders would work with the kangaroo industry on branding, marketing and quality control. The government's role would be oversight and regulation.

    "When someone is rude to you, it can put you in a bad mood. It may even lead you to be rude to someone else, creating a chain of rudeness. In fact, this troubling chain may even be caused by simply seeing someone be rude to another person. You don't even have to be the target of the had behavior," stated a researcher.

    The researchers worked with 81 persons, with occupations ranging from security to business to medicine, who were asked to complete online surveys over a 10-day period. Participants recorded their moods when they woke up; and in the evening, they described their experiences over the course of that day.

    Each morning the participants also viewed a short video, describing workplace interaction of some kind. Half of the mornings, the video included some kind of rudeness while the other half had some kind of warm interaction in the workplace. Rudeness was conveyed through various means, including a lack of eye contact or unpleasant language.

    Participants who watched the rudeness videos reported seeing or experiencing rudeness during the day, and they were also more likely to escape from fellow employees to avoid being the victims of rudeness themselves. They reported their overall work suffered that day as a result.

    Not all participants were affected by the rudeness videos, however. A few weeks before the study began, the participants completed an evaluation that measured their self-confidence and emotional stability among other things. The participants who scored higher on this evaluation were significantly less likely to be influenced by the rudeness.

    Consequently, one of the researchers recommended that companies hire managers who can limit exposure to rudeness, provide plenty of positive reinforcement (强化) and build a civil workplace environment. This, in turn, could help employees build their confidence levels and help them better handle workplace rudeness.

Max Mathews has been called the father of computer music.He created electronic tools so that people could use computers as musical instruments.He had a great influence on the development of electronic music and how it is written,recorded and played.

In 1957,Mathews wrote the first computer program that enabled a computer to create sound.At that time,he was working as an engineer at Bell Laboratories in New Jersey.His computer program enabled a large IBM computer to play a 17 seconds piece of music that he had written.The computer was so slow that it would have taken an hour to play the piece of music in 17 seconds.For that reason,Mathews moved the work to a tape player,which could be sped up to play the music at a normal speed.He later said that the sound quality of the musical notes was not great,but the technical importance of the music was huge.

Mathews continued creating other versions of the music program.He became interested in how computers could help musicians outside recording studios.The Groove program he developed was the first computer program made for live performances.

He also developed an electronic device he called the Radio Baton.The device looks like two drum sticks.It enables the user to control the speed and sound levels of orchestral music playing on a computer.The user does this by moving the two sticks on a special electronic surface.

Mathews believed modern musicians are not making full use of the power of computer music.He said a violin always sounds like a violin.But with a computer,the way a violin sounds is unlimited.He said he didn't want computer sounds to replace live music.But he said he hoped laptop computers would one day be considered serious instruments.
