Thousands of taxi drivers in Shenyang, Liaoning province, reportedly blocked streets with their cars on Sunday in protest against unlicensed cars using taxi-hiring apps (打车软件) and apps-based car rental companies providing passenger services, including high-end cars. Although the drivers also complained about the withdrawal of the fuel subsidy(补贴) by the government, their main complaint was the loss of business because of the rising number of Internet-based car services companies.

    On Wednesday, news reports came that Beijing transport authorities will take measures to stop the illegal “taxi business” of private cars through the newly rising Internet apps, following the footsteps of Shenyang and Nanjing.

    It is not yet clear how the Shenyang city government will handle the issue and whether it will declare the services offered by market leaders such as Didi Dache, a taxi-hiring app provider backed by Tencent Holdings, and Kuaidi Dache illegal. But Shanghai transport regulators(交通管理机构) have set a rule, by banning Didi Zhuanche, or car services offered by Didi Dache in December.

    Such regulations (规定) will cause a setback(挫折) to the car-hiring companies and investors that are waiting to cash in on the potentially booming business. Just last month, Didi Dache got $700 million in funding from global investors, including Singapore state investment company Temasek Holdings, Russian investment company DST Global and Tencent. Besides, the market is uncertain that Kuaidi Dache is about to finalize its latest round of funding after getting $800 million from global investors.

    Regulatory uncertainties, however, could cast a shadow on the future of the Internet-based car-hiring services, which have become popular in most of China's big cities. To be fair, these companies' business model is anything but bad. For example, Didi Zhuanche works side by side with established car rental companies to provide high-end car service mainly for business-people through the Internet and mobile phone apps.

    Every link in this business model chain has legal companies and services. Hence, it is hard to define it as illegal and ban it.

    Doing well in high school prepares students for life in college and beyond, so achieving student success is important. High school students learn valuable information from class lectures and homework, and by asking for help when it is needed. Being prepared for tests and engaging in school activities can help a student to achieve success in high school.

    Complete any homework you are assigned on time. Then, if you need help understanding a concept you will have plenty of time to get help.

    Create a study area in your home. This can be a quiet bench outside or a seating area in your room. If you like to listen to music while studying, listen to classical or relaxing music. Be sure to have plenty of lighting in the area to read your textbook or notes.

    Keep a schedule. If you have extra-curricular activities like sports or school meetings, make sure to schedule your homework and study time around them. Keeping a schedule will allow you to get better grades while they are having fun in high school.

    Eat breakfast. Having breakfast each morning before school will give you energy and brain function to pay better attention in class. Eat snacks during study sessions to keep alert and focused on your work.

    Create a study group to help fellow high school students and get help if you need it. Studying with others will help reinforce concepts and information, and if you need help there will always be someone there to help you before you get behind in your studies.

    Set up after-school hours with your teacher if you need extra tutoring. Visiting a teacher for one-on-one time before a test will help you nail down those last few concepts you need help with.

    No one knows how much money Dr. Lyle Tullis gave away to students. I was his colleague for nearly a decade and I never stopped being amazed at his generosity. Our college has a program of providing cross-cultural experiences for students. Lots of students take advantage of summer experience oversea. I discovered that no group left for overseas with some of its members receiving financial help from Dr. Tullis.

    It wasn't that he made a lot of money. For one thing, he taught in a church-run school. There, his salary was half of what those people earned in a tax-supported school.

    Other colleagues occasionally complained about the low pay. Not Lyle Tullis. Occasionally some professors would leave our campus for a better-paid position. They told me they did so because, with better pay, they could provide for their families.

    The size of Lyle Tullis' paycheck never seemed to be the most important thing to him. I realized that one day when I was thanking him for helping a student, his eyes shone as he said to me, “I've got so much money that I don't know what to do with it. So, I just give it away.”

    Most people wouldn't have thought that way. Dr. Tullis drove one of the oldest cars on campus. It was even older than almost any of the students' cars. His home, while comfortable, was not fancy at all. But Lyle Tullis lived with the feeling that he had so much money that he needed to give it away.

    He was one of the favorite on campus. Cynics(愤世嫉俗者) might say he bought fame. But they would misunderstand. Lyle wanted to devote his life, all of it, to helping others.

    Parents often believe that they have a good relationship with their teenagers. But last summer, Joanna and Henry noticed a change in their older son: suddenly he seemed to be talking far more to his friends than to his parents. “The door to his room is always shut”, Joanna noted.

    Tina and Mark noticed the same changes in their 14-year-old daughter. “She used to cuddle up (依偎) with me on the sofa and talk,” said Mark, “Now we joke that she does this only when she wants something. Sometimes she wants to be treated like a little girl and sometimes like a young lady. The problem is figuring out which time is which.”

    Before age 11, children like to tell their parents what's on their minds. “In fact, parents are first on the list,” said Michael Riera, writer of Uncommon Sense for Parents with Teenagers. “This completely changes during the teen years.” Riera explained. “They talk to their friends first, then maybe their teachers, and their parents last.”

    Parents who know what's going on in their teenagers' lives are in the best position (位置) to help them. To break down the wall of silence, parents should produce chances to understand what their children want to say, and try to find ways to talk and write to them. And they must give their children a mental (精神上的) break, for children also need freedom, though young. Another thing parents should remember is that to be a friend, not a manager, with their children is a better way to know them.

    At first, muffled (听不太清的)conversations made researchers at a San Diego aquarium puzzled, but when a diver thought he was being told to get “out” of the water they realized the conversations were coming from a white whale.

    Noc was about one year old when he was caught off the Pacific coast of Canada. He was kept in an open-ocean pen (围栏) at the US National Marine Mammal Foundation in San Diego, California. After seven years at the Foundation, he began, automatically, to make unusual sounds, a report in the latest issue of the journal, Current Biology, said.

    “We thought of the whale' s vocalizations(发出的声音) as an attempt to imitate humans. Whale vocalizations often sounded as if two people were talking just out of the range of our understanding,” the authors said. “ 'These conversations' were heard several times before we finally realized the whale was the source.” The researchers realized it was Noc when a diver surfaced and asked, “Who told me to get out?” It was then that they realized the word “out”, which was repeated several times, had come from Noc. Later, his speech-like sounds were recorded in the air and underwater.

    Noc started making the sounds after seven years in the open-ocean pen, and continued making them for another four years. He died five years ago. Researchers have now analyzed the sound recordings. It was the first time that sound recordings had shown how such sounds imitated speech and were different from the usual calls of the species.

    The speech-like sounds were lower than normal whale sounds and much closer to those of the human voice. Also, whales talk to each other by blowing air through their noses, rather than using a larynx(喉), as people do.

    “We don't claim that our whale was a good imitator compared to such well-known imitators as parrots,” the researchers said. “However, the behavior we observed is an example of vocal learning by the white whale. It seems that Noc's close association with humans played a role in how often and how well he employed his human voice.”

    Unbelievable Stories of Animals Acting Just Like Humans

    Horses are picky eaters

    Horses have an even better sense of smell than humans do. When horses raise their noses and open their nostrils (鼻孔) , their nervous system allows them to sense smells we can't sense. This might explain why they refuse dirty water and carefully move around meadows, eating only the tastiest grasses, experts say.

    Whale says thanks

    In 2011, a whale expert spotted a humpback whale trapped in a fishing net and spent an hour freeing it. Afterward, in an hour-long display of thanks, the whale swam near their boat and leaped into the air about 40 times.

    Pandas like to be naughty

    Is there anything more lovely than a baby panda, except maybe a human baby? In fact, baby pandas sometimes behave like human babies. They sleep in the same positions and value their thumbs. Pandas are shy by nature for its shy behaviors such as covering its face with a paw of ducking its head when confronted by a stranger.

    A cat honors its owner

    Paper towels, and a plastic cup are just a few of the gifts that Toldo, a devoted three-year-old gray-and-white cat, has placed on his former owner Iozzelli Renzo's grave every day since the man died in September 2011. Renzo adopted Toldo from a shelter when the cat was three months old, and the two formed an inseparable bond. After Renzo passed away, Toldo followed the coffin to the cemetery, and now "stands guard" at the grave for hours at a time.
