    Bees and other pollinators(传粉者)  use smells to track down fresh flowers. Air pollutants can weaken those scents(气味).  Scientists had worried this might make it harder for some pollinators to find a meal.

    Many animals help pollinate plants. Species that do this include bees, butterflies, etc. But for many reasons, the pollinators available to help plants in this way are decreasing. Scientists think a loss of habitat(栖息地)can be one factor. Diseases and exposure to poisonous chemicals also count.

    Jose Fuentes points to air pollution as another possible factor. He's an atmospheric scientist at Pennsylvania State University. In an earlier study, he showed some air pollutants could weaken or destroy scents emitted(发出)by flowers.

    Searching for a meal leaves pollinators out in the open and at risk of becoming other animal's lunch. And any time spent hunting food is time away from their duties back home, like protecting a hive(蜂巢)or nest, explains T'ai Roulston. He's an insect biologist at Virginia University. Roulston worked with Fuentes on the new study.

    In the study, the researchers focused on five kinds of representative scent molecules(分子)plants emit. One molecule they looked at, for example, is called beta-myrcene. Many flowers give off this chemical into the air.  Normally, this gas can travel some 800 meters from its flower source. But in polluted air, this same molecule could travel only half as far.

    Worse still, air pollution might do more than just weaken scent plumes(气味烟云).Chemical reactions between air pollutants and plumes may transform the flowers' smells, creating new scents. And these scents may be unrecognizable to pollinators.

    That's certainly Fuentes' concern.  So, he says his next research project will look at how insects handle any new flower scent. "It's possible that some insects will change ways to detect and use these new molecules to find food," he says.

A、They lose their ability to smell flowers. B、Scented plumes travel in a new direction. C、Flower scents spend more time reaching them. D、Air pollution makes flowers emit fewer scents.
(4)、What is Jose Fuentes' attitude towards insects' ability to adjust to new conditions?
A、Positive. B、Worried. C、Unclear. D、Disappointed.

    Recently, a painting of actress Elizabeth Taylor, which was drawn by American artist and filmmaker Andy Warhol, sold for US $63 million. Another simple black-and-white image of a Coca-Cola bottle sold for US $35 million. But the all-time record for a Warhol painting is $100 million for a piece titled “Eight Elvises”. What's amazing is not that the pieces sold for so much, but the fact that they are not what you would call traditional art. They are “pop art”, art based on simple images of things and people from advertising, movies, music and day-to-day life.

    Born in the 1920s, Warhol grew up mostly separated from other children due to (由于) health problems. He spent a lot of his time alone drawing and then went on to study art in college. He began his career as a commercial (商业的) artist, creating pictures for magazine articles and newspaper ads. That inspired him to experiment with pop art and he hosted America's first pop art exhibition in the 1960s. The show met with a lot of discussion with some people saying that what he was doing was not art.

    Warhol followed his first works with a series we are all familiar with — paintings of Coca-Cola bottles, Brillo soap pad boxes, and portraits (肖像) of famous people. Soon after, Warhol stopped creating his own artwork. Instead, he had assistants and other artists create them at his studio called “The Factory”. Warhol wanted to show the world that art doesn't have to be complex or original; it can be created by anyone using ordinary things.

    Today, Warhol's work is unmistakable in its uniqueness. No matter how you may feel about his work, one thing cannot be argued. He introduced the world to a whole new art form, inspiring future generations of artists, and eventually becoming one of the most famous and successful pop art artists in the world.

    Junxi “Emma” Yang played Carnegie Hall before she got to high school. But her piano skills may have to take a back seat to her programming skill.

    According to World Journal, a US-based Chinese media organization, Emma, a 14-year-old student at the Brearley School in Manhattan, New York started coding when she was 6. Four years later, her beloved grandmother began developing Alzheimer's.

    When Emma's family moved to New York from Hong Kong in 2014, she became passionate about programming. By the time she was 10, her grandmother had already developed the disease.

    Emma got right to work. With her coding skills, she had a smartphone app created before long, designed to help people suffering from Alzheimer's.

    “Now, 'Timeless' has moved to the second stage of design,”says Emma.

    Emma hopes her grandmother can benefit from the artificial intelligence technology built into “Timeless,” the app Emma developed, to overcome her memory loss.

    Emma's newly finished app has gained support from Dr. Melissa Kramps, an Alzheimer's specialist, and from Kairo, a developer specializing in artificial intelligence.

    Timeless uses facial recognition to remind someone with Alzheimer's of vital information about the person whose photo they are looking at on their screen. It also signals whether they have just called somebody.

    The app also allows for the photo-talking, then moves to identify the people on the screen.

    The Timeless project is featured on the website Indiegogo for fundraising. Emma is hoping to raise $50,000 and work alongside professional programmers to have Timeless launched by the end of 2018.

    Many people have hailed Emma for her efforts. Bill Gates voiced his support, commending her on her bid to help bridge the gap between people with Alzheimer's and the ones they love.

    The digital revolution is both launching us into a no-handwriting future, and also sending us backwards in time to when the spoken words ruled. But that's not necessarily a bad thing.

    "I don't think kids should be assessed on their ability to master cursive(草书). It's not something that they are going to use much in their lives as they grow older. It's not something most of us adults use in our lives today. " Anne Trubek, an author, suggests that schools offer handwriting or cursive as an elective or art class in the future.

    "Focus on how to teach kids to express their ideas, how to organize their thoughts, how to make arguments" she says. "The forming of the letters are less important. And there are certainly many ways to individualize what you write beyond the way you've circled the 'I' or crossed your 'T'."

    "This myth that handwriting is just a motor skill (运动技能) is just plain wrong," Virginia Berninger said. "We use motor parts of our brain, motor planning, motor control, but what's very critical is a region of our brain where the visual and language come together and actually become letters and written words."

    "A lot of people are very stubborn about the importance of handwriting, but at the same time will admit they never write themselves," Trubek says.

    Trubek suggests, however, that handwriting keeps some value – for now. " For us today, in the 21st century America, handwriting represents something individual and unique about a person. It doesn't always mean that in previous times in history, and it won't always mean that in the future, but right now for us we relate our sense of self to our handwriting."
