A study published in Child Development,the top－ranked educational psychology journal,provides some of the strongest evidence yet that gesturing may have a unique effect on learning.Teachers in the United States tend to use gestures less than teachers in other countries.

     "Gesturing can be a very beneficial tool that is completely free and easily employed in classrooms," said Kimberly Fenn,study co－author and assistant professor of psychology at Michigan State University."And I think it can have long－lasting effects."

    Fenn and Ryan Duffy of MSU and Susan Cook of the University of Iowa conducted an experiment with 184 second－,third－ and fourth－graders in Michigan elementary classrooms.

    Half of the students were shown videos of an instructor teaching math problems using only speech.The others were shown videos of the instructor teaching the same problems using both speech and gestures.In the speech－only videos,the instructor simply explains the problem.In the other videos,the instructor uses two hand gestures while speaking,using different hands to refer to the two sides of the equation.Students who learned from the gesture videos performed better on a test given immediately afterward than those who learned from the speech－only video.

    Another test was given 24 hours later,and the gesture students actually showed improvement in their performance while the speech－only students did not.

    While previous research has shown the benefits of gestures in a one－on－one tutoring－style environment,the new study is the first to test the role of gestures in equivalence learning in a regular classroom.

    The study also is the first to show that gestures can help students transfer learning to new contexts—such as transferring the knowledge learned in an addition－based equation to a multiplication－based equation.

    Fenn noted that U.S.students lag behind those in many other Western countries in math and have a particularly hard time mastering equivalence problems in early grades."So if we can help them grasp this foundational knowledge earlier," she said,"it will help them as they learn algebra and higher levels of mathematics."

    This happened when I was ten.

    My girl cousin had decided to be a boy for Halloween, so my aunt called my mom to borrow some of my clothes. The next morning, they came to our house early before school. My cousin told me that she was going to be a boy for Halloween and wear some of my clothes. I told her that I didn't care. Then, with a big grin(咧嘴笑) on her face, she told me that I was going to be a girl. I told her she was crazy but she said that she had overheard my mom's plan and that her mom had brought some of her clothes for me.

    So I went to the living room to see our moms. Then I knew she wasn't lying. There was a wig(假发）on the table and my mom and aunt were both smiling at me. I shook my head and told them “NO WAY!” before they even said a word. My aunt said that it would be really cute. Then Mom told me not to be a stick-in-the-mud. She said that it would be fun and she wanted to see what I'd look like as a little girl. I told them I absolutely would not do it!

    I was still refusing twenty minutes later… when my aunt was putting make-up on me. I was wearing a pink party dress, the blond wig with pigtails(辫子) and earrings. My cousin wore one of my sweatshirts, my jeans and a baseball cap. We were sent to school like that, where I spent a sad day. The kids thought it funny that we were dressed that way and made stupid comments about us. They also played jokes on us and I've never been so uncomfortable.

    I still don't like Halloween to this day!

    Clothes can make phone calls, play music, dial your pal's number, keep you warm during cold weather and operate your computer?

    This is not a fantasy. A British company, called Electrotextiles, has created a wide range of clothes—clothes that have minds of their own! Scientists, working for the company, have invented a kind of cloth that can be mixed with flexible (有弹性的) electronic materials to create intelligent clothing. The results are electronic garments (衣服).

    If you think the wearer has to be wired to different devices, think again. These designer clothes are wire-free, soft to touch and washable! Like any electronic device, these high-tech clothes have to be powered. Currently, a tiny nine-volt battery serves the purpose. But the researchers hope that in the near future the clothes will produce electricity by using body heat. These clothes are 100 percent shock proof, they say.

    The Electrotextiles team has also created the world's first cloth keyboard. This keyboard can be sewn into your trousers or skirt. To use this device, you will have to sit down and tap on your lap! These 'lap-tap' gadgets (器具), are all set to take over laptop computers!

    Another useful garment is the shirt-cum-mobile phone. This handy invention enables drivers to chat comfortably with others at the wheel! Other popular electronic wear include the denim (牛仔布) jacket with flexible earphones sewn into the hood and the electronic ski jacket with a built-in heater. The ski jacket is also programmed to send signals to a satellite. This technology is known as global positioning system and can be used to track lost skiers and wandering kids.

    Having completed the cloth keyboard, scientists have already started to work on a new project—a necktie that can be used as a computer mouse. What is the next? Do you have any idea?

    It seems we're always being told to get more sleep. Studies suggest spending less time on sleep can lead to obesity(肥胖) and even cancer. You might even find yourself with a head full of false memories. But rarely does science explore the dark side of sleeping too much. That's because few of us in today's busy world have the luck of exploring that option.

    In an August 2018 study, published in the Journal of the American Heart Association, researchers researched the sleep patterns of those "fortunate" few and found they may not be so lucky after all. In fact, they found people who get more than eight hours of sleep have greater health risk compared to those who sleep together less than seven hours. What's more, sleep-aholics-those who manage to get 10 hours a night-stand a 30 percent higher chance of dying compared to the seven-hour crowd.

    The wide-ranging global study involved(涉及) more than three million people who self-reported on their sleep habits and came to an eye-opening conclusion: If you tend to sleep a lot, you may want to buy an alarm clock. As with all things in life, sleep is best taken in moderation(适度).

    You may be thinking: What if I only sleep in on Saturday and Sunday, am I still at risk? The answer is yes, according to a 2019 study published in Current Biology.  Researchers discovered that even if a person sleeps more than seven hours on the weekends but still sleeps less than that on weeknights, they are at risk of gaining weight and developing sensitivity to insulin, which controls the level of sugar in blood.

    For the study, 36 participants were divided into three groups that each had a different sleep schedule: nine hours every night, five hours every night, and five hours from Monday to Friday and sleeping much on weekends. People who get too much sleep tend to feel tired and lack energy. Also, both sleep-deprived(睡眠不足的) groups consume more food and gain weight.
