Marlene Dietrich is finally to be honored by her home city, Berlin.

    For more than half a century, the famous film star won huge fame in Hollywood, but remained a highly controversial（引起争议的） figure in Germany.

    When the city's new film museum is opened on September 26, three of its 15 rooms will show the star's possessions collected over a lifetime.

    In addition to various collections by Marlene, visitors will be able to see all Marlene Dietrich's movies. There will also be key except for a vast range of Germany-made films.

    Dietrich became a world star after her wonderful performance in a movie. After that, she turned her back on Germany, horrified by the sudden movement of Nazi in her hometown.

    A few years after the war, the star was persuaded to pay a short visit to Berlin. But the trip proved a disaster. At a city hall gathering in West Berlin, crowds turned out to see her, but not all friendly.

    She was attacked at times. She found herself being blamed for wearing an American uniform during the war to please U.S. troops in Europe. She was also scolded for "turning her back on the country".

    Dietrich, deeply hurt, decided she would never return to Berlin again. But she softened her judgment.

    When she died in Paris in 1972, it was at her express wish that her body should be sent back to Berlin for burial alongside her mother in a local cemetery.

    The loneliest chimp(黑猩猩)in the world just got the best surprise—a hug from a new friend．Ponso has been by himself for nearly three years，finding himself alone after his wife and children died on the island where they were abandoned by a medical testing company many years ago．

    For years a nearby villager named Germain has been Ponso's only company，visiting him so often to bring bananas and bread—the chimp's only source of food on the tiny island．It was clear how much Ponso missed companionship when he was recently visited by Chimpanzee Conservation Centre Director Estelle Raballand．The chimp immediately embraced Estelle Raballand in a huge hug and laughed as she reached out for him，with his smile from ear to ear．

    For those who know Ponso's backstory，his immediate ease and trust in humans might be surprising．Ponso was one of 20 chimps，all between the ages of 7 to 11 years old，relocated to an island off the Ivory Coast after being used for testing by the New York Blood Centre．After the tests were completed in 2005，the lab reportedly transferred the chimps to a string of islands，occasionally dropping off food and water because there was none in the chimps' new homes．

    Disease and hunger soon left only Ponso，his mate and their two children standing．But at the end of 2013 they died within days of each other and Ponso was now completely alone．

    A group called SOS PONSO is trying to raise money for the poor lonely chimp，already achieving its goal of $20,000 - all of which will be used for Ponso's care．

    Your next ca might drive itself. After years of trials on city streets, driverless vehicles are now nearing the live phase. Last moth, a driverless bus began carrying passengers through Lyon, France, Most in the automobile industry think self-driving vehicles will be on the road by 2020 or before.

    Driverless cars will at first be huddled with human-driven cars. But the first places where they will become dominant（统治的）are dense urban areas — precisely the spots most damaged by the automobile age. Many advanced cities are already reducing the role of human-driven cargo. Driverless cars will quicken that process and will bring us enormous benefits.

    Driverless cars will reduce accidents by around 90 percent. That's big—the annual death toll on the world's roads is about 1.2 million a year. Pollution and carbon emissions will drop, because urban driverless cars will be electric. The old, otherwise they would stay at home most of the time and the disabled and teenagers will suddenly gain mobility.

    On the other hand, driverless cars will bring catastrophe. The best thing about the automobile age was that it employed tens of millions of people to make, market, insure and drive vehicles. Over the next 20 years, the mostly low-skilled men who now drive trucks, taxis and buses will see their jobs reduced. Carmakers are especially scared. The few cars of the future might be made by tech companies such as Apple, Baidu and Google. Imaging the impact on Germany, where the automotive sector is the largest industry.

    Dramatic change is coming, and driverless cars could arrive by 2020. But governments have barely begun thinking about it. Only 6 percent of the biggest US cities have factored them into their long-term planning.

    A decade ago anyone hardly saw the Smartphone coming. It has bought an epidemic of mass addiction. Let's hope we do a better job of handling the driverless car.

Most people, when they travel to space, would like to stay in orbit for a few days of more. And this stands to reason, if you're paying $20,000 for your trip to orbit! Strain order for tourism to reach its full potential there's going to be a need for orbital accommodation—or space hotels. What would a space hotel actually be like to visit? Hotels in orbit will offer the services you expect from a hotel—private rooms, meals, bars. But they'll also offer two unique experiences: impressive views—of Earth and space—and the endless entertainment of living in zero gravity—including sports and other activities that make use of this.

The hotels themselves will vary greatly—from being quite simple in the early days to huge luxury structure at a later date. It's actually surprising that as later as 1997; very few designs for space hotels were published. This is mainly because those who might be expected to design them haven't expected launch costs to come down far enough to make them possible.

    Lots of people who've been to space have described vividly what it's like to live in zero gravity. There are obviously all sort of possibilities for dancing, gymnastics, and zero-G sports. Luckily, you don't need to sleep much living in zero gravity, so you'll have plenty of time for relaxing by hanging out in a bar with a window looking down at the turning Earth below.

Of course all good things have come to an end. Unfortunately, and so after a few days you'll find yourself heading back enough you'll be much more expert at exercising in zero gravity than you were when you arrived. You'll be thinking how soon you can save up enough to get back up again—or maybe you should change jobs to get to work in an orbiting hotel.

    Attention from strangers is nothing new to me. Questions about my height is the center of almost every public interaction. My friends say my height is just a physical quality and not a personality aspect. However, when I reflect on my life, I realize that my height has shaped my character in many ways and has helped to make me who I am.

    I learned how to be kind. When I was younger, some parents in my neighborhood regarded me kind of dangerous because I was so much larger than other children of my age. I had to be extra welcoming and gentle simply to play with other children. Of course, now my coaches wish I weren't quite so kind on the basketball court.

    I learned the quality of not being too proud about myself. At 7 feet tall, everyone expects me to be an amazing basketball player. They come expecting to see Dirk Nowitzki, and instead they might see a performance more like Will Ferrell (successfully starred a professional basketball player). I have learned to be modest and to work even harder than my fellows to meet their (and my) expectations.

    I developed a sense of lightheartedness. When people playfully make fun of my height, I laugh at myself too. On my first day of high school, a girl dropped her books in a busy hallway. I got down to her level and gathered some of her notebooks. As we both stood up, her eyes widened as I kept rising over her. Astonished, she dropped her books again. Embarrassed, we both laughed and picked up the books a second time.

    All of these lessons have defined me. Looking back, I realize that through years of such experiences, I have become a confident, expressive person. Being a 7-footer is both a blessing and a curse (诅咒), but in the end, accepting who you are is the first step to happiness.

    Language learning apps are very popular now and offer opportunities to learn vocabulary and practice grammar. But there has been a discussion about just how effective such apps can be.

    Among the most popular apps are Duolingo and Busuu. A previous research found positive results on the use of them. But it mainly concentrated on studies with learners who had signed up to language courses and these apps worked as an after-class support, so the results were not always reliable. A recent study of 4,095 Busuu users has been carried out aimed to find out if users can actually learn a language with an app.

    Busuu provides learning materials for 12 different languages. It offers special model where some content is available for free while some content is not. We find that its users are an even mix of men and women. More than half consider themselves to be at the beginner level as there is a decrease in users as their language levels go up. Most people use the app because of personal interest, or because they want to study or live abroad. Female users tend to use it less often but for longer periods of time than male users.

    Getting any feedback on Busuu depends on whether your answer is correct or not. While it is helpful, this is not the sort of feedback language teachers prefer, as it does not explain why the answer is right or wrong. In spite of this, feedback in the app is very highly rated.

    More than 92% of respondents state that the app has met their expectations and 86% rate the app as very good or good. In fact, more than 80% of the users surveyed strongly agree that using the app has helped them improve their knowledge of the language they are learning.

    Besides, language learning apps also create an environment where mistakes are only known to the users, and this can address the performance anxiety that many learners suffer from when asked to speak a foreign language. So language teachers should encourage their students to use them to do the grammar work, leaving precious class time for more language communication.
