The percentage of women working in technology has decreased since the 1990s.Women make up only a quarter of all jobs in computer and math professions.I think all girls should learn how to code（编码）.Here is why.

    If we want to be part of one of the fastest growing job markets out there,we need to jump on board!Over the last ten years the growth in STEM jobs has been three times faster than that in non-STEM fields.Women will never be able to keep up with men in the professional workplace if we don't join the fastest growing fields.

    Just like hundreds of years ago,people who could read and write controlled the future,and now those who are at home with technology will shape the world we live in.You can use coding in every aspect of your life,even if you don't enter a field that involves coding.You cant use coding to create your own website or to program games.You can animate your YouTube videos,or make graphic designs.Programming is now being used in every profession, including medicine and airplane design.

    You can have fun creating your own website,programming a robot to get the remote for you when you're lying on the couch,photoshop pictures to change the color scheme to something better than the Instagram filters,and so much more.Coding allows you to realize your wildest dream,and create anything you can imagine.Coding allows you to rule the world.

    It's not very hard to learn to code.You could learn to code on YouTube,in the Girls Who Code club;you could take a free course online on Code Academy;you could even just Google how to code.

You learned to read,you learned to drive-now learn to code.

    As the new semester begins, millions of college students across the country are trying hard to remember how best to write a paper or, more likely, how best to delay that paper.

    Procrastination is the thief of time and a lot of students suffer form it. They can spend whole days in the library doing nothing but staring into space, eating snacks, surfing the Internet, watching videos and looking at other students sitting around them, who, most likely are doing nothing either.

    Paralyzed (使失去活力) by their habit to procrastinate, they write micro blogs about their fears, asking their online friends if they sometimes have the same issue. But this does nothing to break the spell (魔咒).

    According to a recent report, 95 percent of us procrastinate at some point and 20 percent of the world's population are always procrastinating. The figures are disappointing. Procrastinators are less wealthy, less healthy and less happy than those who don't delay. Procrastinators like to find excuses to justify their behavior, but BBC columnist Rowan Pelling says they are all wrong.

    Many procrastinators tell themselves they are perfectionists who work best under pressure. Pelling says this is non sense, as work done at the last minute is more likely to have mistakes than work done on time. The behavior of procrastinators often makes them feel ashamed, inconveniences others and annoys loved ones.

    Pelling also points out that procrastination feels particularly delinquent（过失的） in a society that thinks of speedy action as admirable, and, at times, even as a moral good.

    Fortunately, social scientists have thrown their weight behind efforts to understand this behavioral mistake and offer strategies to control it. Piers Steel, a Canadian social scientist and author of The Procrastination Equation, believes human is “designed” to procrastinate. Nevertheless, he suggests a couple of good ways to get through the task at hand.

    Mark and his brother Jason both were looking at the shining new computer enviously. Jason was determined not to go against their father's wishes but Mark was more adventurous than his brother. He loves experimenting and his aim was to become a scientist like his father.

     “Dad will be really mad if he finds out you've been playing with his new computer” Jason said, “He told us not  to touch it.”

     “He won't find out,” Mark said, “I'll just have a quick look and shut it down.”

    Mark had been scolded before for touching his father's equipment. But his curiosity was difficult to control and this new computer really puzzled him.

It was a strange-looking machine — one his dad had brought home from the laboratory where he worked. “It's an experimental model,” his father had explained, so don't touch it under any circumstances.” But his father's warning only served to make Mark more curious. Without any further thought, Mark turned on the power switch. The computer burst into life and seconds later, the screen turned into colours, shifting and changing, and then two big white words appeared in the centre of the screen: “SPACE TRANSPORTER.”

     “Yes!” Mark cried excitedly, “It's a computer game. I knew it! Dad's only been pretending to work. He's really been playing games instead!” A new message appeared on the screen:

“ENTER NAMES

VOYAGE 1

VOYAGE 2

    Mark's finger flew across the keyboard as he typed in both of their names.

“INPUT ACCEPTED.

START TRANSPORT PROGRAM.

AUTO-RETRIEVE INITIATED( 自动回收程序已启动).”

    The screen turn even brighter and a noise suddenly rose in volume.

     “I think we'd better shut it off, Mark,” Jason yelled out in terror, reaching for the power switch. A beam(光束) of dazzling white light burst out of the computer screen, wrapping the boys in its glow(光芒)，until they themselves seemed to be glowing. Then it died down just as suddenly as it had burst into life. And the boys were no longer there. On the screen, the letters changed：

“TRANSPORT SUCCESSFUL．

DESTINATION:  MARS.

RETRIEVE DATE:  2025

    While famous foreign architects are invited to lead the designs of landmark buildings in China such as the new CCTV tower and the National Center for the Performing Arts, many excellent Chinese architects are making great efforts to take the center stage.

Their efforts have been proven fruitful. Wang Shu, a 49-year-old Chinese architect, won the 2012 Pritzker Architecture Prize — which is often referred to as the Nobel Prize in architecture —on February 28. He is the first Chinese citizen to win this award.

    Wang serves as head of the Architecture Department at the China Academy of Art (CAA). His office is located at the Xiangshan campus of the university in Hangzhou, Zhejiang Province. Many buildings on the campus are his original creations.

    The style of the campus is quite different from that of most Chinese universities. Many visitors were amazed by the complex architectural space and abundant building types. The curves (曲线) of the buildings perfectly match the rise and fall of hills, forming a unique view.

    Wang collected more than 7 million abandoned bricks of different ages. He asked the workers to use traditional techniques to make the bricks into walls, roofs and corridors. This creation attracted a lot of attention thanks to its mixture of modern and traditional Chinese elements.

    Wang's works show a deep understanding of modern architecture and traditions. Through such a balance, he had created a new type of Chinese architecture, said Tadao Ando, the winner of the 1995 Pritzker Prize.

    Wang believes traditions should not be sealed in glass boxes at museums. "That is only evidence that traditions once existed," he said.

    "Many Chinese people have a misunderstanding of traditions. They think tradition means old things from the past. In fact, tradition also refers to the things that have been developing and that are still being created, "he said.

    "Today, many Chinese people are learning Western styles and theories rather than focusing on Chinese traditions. Many people tend to talk about traditions without knowing what they really are," said Wang.

    The study of traditions should be combined, with practice. Otherwise, the recreation of traditions would be artificial and empty, he said.

    My college experience included this life-skill lesson: Drink alcohol on a full stomach. Or you will get inebriated too quickly. Of course, most college students shouldn't be drinking at all, but we know from the National Institute on Alcohol Abuse and Alcoholism that close to 60 percent of college students aged 18 to 22 do consume alcohol, which makes harm-reducing approaches important.

    Unfortunately, campus authorities and researchers are reporting a practice that turns the full-stomach drinking strategy on its head: rather than filling up before a night of partying, significant numbers of students refuse to eat all day before consuming alcohol.

    This is a high-risk behavior called "drunkorexia," which is one part eating disorder, one part alcoholism—a very dangerous combination for college-age students. The term drunkorexia, which can also include excessive exercise or purging before consuming alcohol, was coined about 10 years ago, and it started showing up in medical research around 2012. Drunkorexia addresses the need to be the life of the party while staying extremely thin, pointing to a flawed mind-set about body image and alcoholism among college students, mostly women.

    Imagine this scenario: A female college freshman doesn't eat anything all day, exercises on an empty stomach, then downs five shots of tequila in less than two hours. Because there's no food in her system to help slow the absorption of alcohol, those shots affect her rapidly, leading to inebriation and possibly passing out, vomiting or suffering alcohol poisoning. That's drunkorexia.

    Tavis Glassman, professor of health education and public health at the University of Toledo in Ohio, researches drunkorexia and worries about scenarios such as the one described above: "With nothing in her system, alcohol hits quickly, and that brings up the same issues as with any high-risk drinking: getting home safely, sexual assault, unintentional injury, fights, hangovers that affect class attendance and grades, and possibly ending up in emergency because the alcohol hits so hard," he says.

    "Alcohol can negatively affect the liver or gastrointestinal system, it can interfere with sleep, lower the immune system and is linked to several types of cancers," Hultin says.

Video calls are a common occurrence, but have you imagined being able to touch the person on the other end of the line? Scientists are making this a reality.

Researchers at the University of New South Wales, Australia, have invented a soft skin stretch device (SSD), a haptic device that can recreate the sense of touch. Haptic technology can mimic the experience of touch by stimulating localized areas of the skin in ways that are similar to what is felt in the real world, through force, vibration or motion.

Vibration is the most common haptic technology today and has been built into many electronic devices, such as one attached to the back of a trackpad in laptops. However, haptic feedback with vibration becomes less sensitive when used continuously. The existing technology also has great difficulty recreating the sense of touch with objects in virtual environments or located remotely.

The new technology overcomes issues with existing haptic devices. The research team introduced a novel method to recreate the sense of touch through soft, artificial "muscles".

It works like this: imagine you call a friend in Australia. You wear a haptic glove with the SSDs and your friend also wears a glove with 3D force sensors. If your friend picks up an object, it will physically press against your friend's fingers. And the glove with 3D force sensors will measure these interactions. The force signals can be sent to your glove so your device will generate the same 3D forces, making you experience the same sense of touch as your friend.

The haptic devices could be used in various fields, allowing users to feel objects inside a virtual world or at a distance. This could be especially beneficial during such times like the COVID-19 pandemic when people rely on video calls to stay connected with loved ones. Or it could be used in medical practices. Doctors can feel a patient's organ tissues without touching them.
