I was asked in an e­mail about learning idioms in a foreign language. Maybe I am different from most people，but I do not bother with them. To me they are kind of dessert of language learning. They come at the end of a meal. Once you have filled up with the key words and phrases that are used in a variety of situations，then you can add a few idioms. And by that time, you will be able to pick them up naturally anyway.

    I find that many learners have trouble with idioms，as if repeating some very colloquial expressions is going to upgrade how they sound in a language. In fact, it is the opposite. Idioms are difficult to use correctly.

    Yes，occasionally you hear idioms and do not understand. But，in my experience，there are always situations where you do not understand. It is best to focus on the most important words，what they mean and how they are used. Certainly，it is best for a non­native speaker to stick to standard speech.

    Some teachers even try to teach the “real language”．Then you hear non­native speakers saying things like “I goanna”, “You wane” etc.

    You will learn all the idioms you need just by exposing yourself to the language. In general，you can save any phrase that you find interesting，and if that includes idioms，go to it. But I would not make any special effort to go after idioms. I，in fact，avoid them. If I come across something in Russian that strikes me as a particularly idiomatic use of words，I just leave it aside; do not even bother trying to learn it. If it keeps on appearing，then I will learn it.

    My students entered the art room with their usual eagerness to see what they would be learning in today's class. Little did they know they were going to be students for a new teaching method that is spreading the nation.

    I often use videos as previews and supplements (补充) to our art lessons providing students with a variety of artists showing their skills in real-life situations outside the classroom. Finding a new painting technique called glue batik(胶水蜡染),  I thought of something new I hadn't tried before!  How awesome would it be to learn a new technique together with artists? The lesson was planned, presented to the students without any introduction or set objectives. I also asked the students to watch and pause the video as often as they needed to.

    They watched as the artist explained and showed her skills, taking notes on her steps and results. After the video, they shared what they felt the artist's objectives were, her end result using art vocabulary as well as the steps they would need to know to present their own examples. Then they began creating their works using the glue batik technique.

    Surfing the Internet a couple of weeks later, I found that the teaching method I used sounded very familiar to a new movement in education called flipped teaching, which was developed by Jonathan Bergmann. He asked his students to watch video lectures at home and do exercises (homework) in class under supervision (监督). He found that grades went up and he also found time for other types of activities, which Bergmann states are more important than the videos.

    Back to my art class, the students were learning to get ideas, make predictions, and explain reasoning to their classmates. Together they compared, asked questions and made discoveries as they presented the technique.

    A few weeks ago, I called an Uber to take me to the Boston airport for a flight home for the holidays. As I slid into the back seat of the car, the warm intonations(语调) of the driver's accent washed over me in a familiar way.

    I learned that he was a recent West African immigrant with a few young children, working hard to provide for his family. I could relate: I am the daughter of two Ethiopian immigrants who made their share of sacrifices to ensure my success. I told him I was on a college break and headed home to visit my parents. That's how he found out I go to Harvard. An approving eye glinted at me in the rearview window, and quickly, we crossed the boundaries of rider and driver. I became his daughter, all grown up — the product of his sacrifice.

    And then came the fateful question: "What do you study?" I answered "history and literature" and the pride in his voice faded, as I knew it might. I didn't even get to add "and African-American studies" before he cut in, his voice thick with disappointment, "All that work to get into Harvard, and you study history?"

    Here I was, his daughter, squandering the biggest opportunity of her life. He went on to deliver the age-old lecture that all immigrant kids know. We are to become doctors (or lawyers, if our parents are being generous) — to make money and send money back home. The unspoken demand, made across generations, which my Uber driver laid out plainly, is simple: Fulfill your role in the narrative(故事) of upward mobility so your children can do the same.

    I used to feel anxious and backed into a corner by the questioning, but now as a junior in college, I'm grateful for their support more than anything. This holiday season, I've promised myself I won't huff and get annoyed at their inquiries. I won't defensively respond with "but I plan to go to law school!" when I get unrequested advice. I'll just smile and nod, and enjoy the warmth of the occasion.

    Claude Monet, Pablo Picasso and Leonardo da Vinci ... the art world has never lacked talent. And now, a new painter is ready to join the list although this one isn't even human.

    Next month, auction house Christie's Prints and Multiples will make history by offering the first piece of art created by artificial intelligence (AI) for sale. The painting is a portrait of a man called Edmond De Bela- my, and is expected to be sold for up to $10,000.

    The work, which features a man with a mysterious look on his face, was created by software developed by the French art group Obvious. Laugero-Lasserre, an art collector, called the work "grotesque and amazing at the same time". This isn't the first example of Al-produced artwork, as AI has already been used to write poems and compose .songs. However, many people doubt whether it should be called art at all.

According to Russian writer Leo Tolstroy (1828 -1910), art is about creating emotion (情感). It's "a means of …joining people together in the same feelings' he once said.

So, if the emotion behind art is what makes it, the ability to create and use tools is what makes human Icings different from other species. And as a tool itself, the AI technology used to create the portrait is the result of a lot of effort made by several designers. Together, they "fed" the AI a huge collection of paintings from the 14th to the 18th centuries, until it was able to work out how to make similar paintings of its own.

    The introduction of AI art could be the beginning of a new artistic movement. However, not everyone is ready to welcome these high-tech artists just yet.

    "The human mind is what's behind the AI technology. And the human mind is not a cold, hard fact," said Oscar Schwartz, a professor of AI. "Rather, it in something that's created with our opinions and something that changes over

    Why visit

    In 1824, the Franklin Institute opened in Independence Hall in memory of Benjamin Franklin and his scientific achievements. In 1934, with the construction of the current building and the nearby Eels Planetarium, it became a hands-on science museum.
