Australia's koalas could die out within 30 years unless immediate action is taken to stop the losing in population, according to researchers. They say development, climate change and bushfires have all combined to reduce the number of wild koalas sharply.

    The Australian Koala Foundation said a recent survey showed the population could have dropped by more than half in the past six years. The number of koalas was once estimated to be more than 100,000, but now is as few as 43,000.

    The foundation collected field data from 1,800 sites and 80,000 trees to calculate the numbers. In one area in northern Queensland estimated to have 20,000 koalas a decade ago, a team of eight people could not find a single animal in four days of searching.

    The foundation said besides problems caused by cutting down forests, hotter and drier conditions because of global warming had reduced the nutritional value of their main food, eucalyptus (桉树) leaves, leading to poor nutrition for them. Koalas, which live in the forests in Australia's east and south, are very picky about what types of the leaves they eat.

    Foundation chief Deborah Tabart said: “The koalas are missing everywhere we look. It's really no tree, no me. If you keep cutting down trees you don't have any koalas.”She is hoping the new figures will persuade the government's Threatened Species Steering Committee (TSSC) to list the koala as threatened. But committee chairman Bob Beeton said a decision was not likely recently and the koala's status as one of the country's favorite animals would not be a factor. “There's a number of species which are attractive and people have special feelings towards them. We don't consider that,” Mr Beeton said.

    One of the most practical parts of my college education (and my entire education)was my student teaching. For six month, I gradually took over until I was completely teaching the class. It wasn't quite the same as a real teaching job. However, it was definitely a good way to get some real world experience. School should prepare students for the job market. Therefore, are our kids receiving enough practical education so they can be successful in the real world?

When teaching kids, it's important to be able to have a purpose for everything we teach. As parents and teachers, we should ask ourselves: what can this be used for when kids enter the job market? I can think about a college class I took where we had to analyze various movies. I honestly can't think of how analyzing "Rambo" benefited me. Perhaps, I would have been better off taking an auto shop class or a carpentry class. After all, I can't change a tire and I'm completely incapable when it comes to using power tools. The Guardian points out that the current generation is one of the most educated but lacks the skills to mend a hole in a shirt or put up a shelf. We have become a society that hires someone else to do these basic tasks. So how can we fix this?

    Perhaps, learning how to think is not enough. Rather than focusing on standardized tests so much, schools need to give students more practical application. Cooking is actually helpful when teaching children about fractions, measuring and multiplication. Students can learn how to double a recipe and see the relationship between 1/4 and 1/3 cup. As kids get into the upper grades, money management should be a focus. Making a budget and learning about interest rates are good ideas. I used to give my students real restaurant menus and a budged. They had to come up with what they could buy, including the tip with a set amount of money. In college, rather than only focus on the craft of writing, I wish I would have learned more about marketing and publishing my writing. Finally, internships in both high school and college should be required.

It appears that some high schools are doing a better job of preparing students for the real world. For instance, according to NBC News, in Michigan, "the Utica Center for Science and Industry uses technology to prepare students for automotive and military industry jobs." The program aims to combine students' skills with employers' needs. Students take optional courses in areas such as "multimedia, engineering or mechatronics" and also take part in activities where there isn't one right answer. For me, giving kids the opportunity to create is the key point. So far, the program is showing success.

According to a Gallup poll, fifty-seven percent of American workers say "the type of work they do generally" does not require "a bachelor's or a more advanced degree." Therefore, if a college degree isn't helping the majority of Americans at their job, then what is required? Many jobs require a skill. Electricians and contractors have specific skill that allow them to complete their jobs. Whether students go to four-year school or not, I think it's important for everyone to have a skill. After all, a Forbes article states that half of college graduates are working at jobs that don't require a degree. Clearly, being smart and qualified isn't always enough to make it in the real world.

    I'm going to encourage my kids to go to college and earn a degree. I'm also going to encourage them to think outside of the box and give them a practical education too. After all, you never know where life will take you.

    It was close to midnight and it was unusual to see vehicles on the road. However, several trucks pulled over and workers silently unloaded camera equipment and cardboard boxes, and then carried them inside the Morgenson family home.

    What took place over the next eight weeks was inspired by a Hollywood movie called The Joneses about a family of marketers who move into a local neighborhood to sell their products secretly to their neighbors. The idea was to test the power of word-of-mouth marketing. By filming a 'rear' family in unscripted (无剧本的) situations, my team and I would document how the Morgensons' circle of friends responded to brands and products the Morgensons bought into their lives.

    With the help of 35 video cameras and 25 microphones hidden inside the furniture, the operation done secretly showed something shocking. The most powerful hidden persuader of all isn't in your TV or on the shelves of your supermarket. It's a far more important influence that's around you almost every waking moment: your very own friends and neighbors. There is nothing quite so persuasive as observing someone we respect or admire using a brand or product.

    Our analysis also found that the brands the Morgensons used went faster. About one third of the Morgensons' friends began promoting these same brands to their friends. We also found that the brands their friends were most likely to buy at the Morgensons' suggestion were the bigger and better-known ones. This proved my thoughts that traditional marketing and secret marketing work well together. The most persuasive advertising strategies are strengthened by word-of-mouth advertising.

    Whenever I meet with company managers, I tell them that the people who hold the real marketing power are mouse-clicking consumers and their wide circles of real-life friends. In other words, the people who hold the real power are us.

    Driving a car is not just handling controls and judging speed and distance. It requires you to predict what other road users will do and get ready to react to something unexpected. When alcohol is consumed, it enters your bloodstream and acts as a depressant (抑制药),damaging eyesight, judgment and co­ordination(协调),slowing down reaction time and greatly increasing the risk of accidents. Even below the drink driving limit, driving will be affected.

    Alcohol may take a few minutes to be absorbed into the bloodstream and start action on the brain. Absorption rate is increased when drinking on an empty stomach or when consuming drinks mixed with fruit juice. To get rid of alcohol from the body is a very slow process and it is not possible to speed it up with any measures like taking a shower or having a cup of tea or coffee.

    The present Road Traffic Ordinance states clearly that the limit of alcohol concentration is： 50 milligrams of alcohol per 100 ml of blood； or 22 micrograms of alcohol per 100 ml of breath; or 67 milligrams of alcohol per 100 ml of urine (尿液)．

    Drivers who cause traffic accidents, or who commit a moving traffic offence or are being suspected of drink driving will be tested.

    Any driver found drinking beyond the limit will be charged. The driver declared guilty may be fined a maximum of HK $ 25000 and be sentenced to up to 3 years in prison and punished for 10 driving­offence points; or temporarily banned from driving.

    The same punishment applies to failing to provide specimens (样本)for breath, blood or urine tests without good excuse.

    Drink driving is a criminal offence. Be a responsible driver, think before you drink. For the safety of yourself and other road users, never drive after consuming alcohol.

    The audiences of the UK will have an opportunity to enjoy a feast of Chinese culture when the China National Peking Opera Company returns to the country for the fourth time for a series of workshops and performances. Events will be held at the British Library, Oxford's Ashmolean Museum and the world-famous dance theater of Sadler's Wells, featuring artists including Lisa Lu, Yu Kuizhi and Li Shengsu.

    On Thursday at the British Library, Lisa Lu, who also played a role in recent cinema hit Crazy Rich Asians, will lead a group of artists from China, the US and the UK to discuss their experiences of working across a variety of artistic fields in different cultures over many decades.

    The series of activities also include interactive workshops, which explain the intricacies（错综复杂）of the attractive art of Peking Opera. The secrets behind a great opera, from music to instruments, from make-up to martial arts, will be revealed at the British Library workshops on Saturday and Sunday.

    Events end on Oct 19 and 20 at Sadler's Wells in North London, with two performances of The Emperor and the Concubine, one of the most celebrated operas, as well as The Crossroads Inn and The Monkey King and The Leopard.

    Li Shengsu, who led the cast of The Emperor and the Concubine, explained that the show is the beautiful love story championed by Peking Opera Master Mei Lanfang, and it is one of the very few works from the Master Mei's that had been handed down since 1920s.

    The productions are being presented in partnership with London-based Sinolink Productions, a company that promotes Chinese art, culture and performance to British audiences.

    Zhang Kewei, producer and director of Sinolink, said, “It is delightful to see that the China National Peking Opera Company returns to London for the fourth time with another two masterpieces this year. The performances so far have received very positive comments from audiences and the United Kingdom's media and we are looking forward to further expanding our program.”

    Like any new ninth-grader on the first day of school, Joemar Class had ninth-grader- emotion (情绪). He's not used to school in Hartford. He's used to going to school in his home town of Florida, used to seeing his friends, used to having class in Spanish.

    "Nervioso," he said in Spanish.

    We first met Joemar in mid-October in the San Juan Airport. His father, Guillermo Class, had sold his car to buy plane tickets to get his kids and fly them up from Puerto Rico. The island was almost destroyed (毁坏) by the deadly storm—Hurricane Maria.

    Now, they are settling into their new home in Hartford's South End. A week later, and, using his wife's car, Class drove 16-year-old Joemar to his first day at Bulkeley High School. After a short ride, he got out in front of his new school. Inside, he met Gretchen Levitz—the school's program director.

    "I see you have new uniform (校服)," Levitz said. "You look great. Are you ready for a good first day?"

    Then he met couple of teachers.

     "Hello," they each said in Spanish. They asked where he's from, and told him they were happy to see him. Then Levitz took him on a quick tour of the school before classes began—to her office the school store, the library, and the dining hall.

    A total of 19 languages are spoken in Bulkeley High School. "We have so many new students coming here from other countries every single day," Levitz said. "So it's not like he's the only one who has that feeling."

    "You could tell he's little worried," Guillermo said as we left." But, at the same time, he's looking forward to it."
