    Exercise could not only benefit your body, but also imp rove your memory, researchers found recently. In their paper published on Monday, researchers from the University of California, Irvine in the United States and the University of Tsukuba in Japan introduced their experiment and conclusion.

    Scientists invited 36 volunteers who were in their early 20s to do 10 minutes of light exercise before taking a memory test in which they were shown pictures like broccoli(西兰花)or picnic baskets and asked to recall them later. The same experiment was repeated with the same group of volunteers without exercising. "The memory task was really quite challenging ,said Michael Yassa, co-author of the study and a neuroscientist (神经科学家)at the University of California, Irvine. "We used very tricky similar items to see if they would remember whether it was this exact picnic basket versus (对抗)that picnic basket. "

    Researchers also scanned brains of some of the participants during the experiment. They found strengthened communication between regions involved in the storage and recollection of memories in brains of those who had exercised. This suggested that just 10 minutes of light exercise like walking, yoga or Tai Chi might increase memory power.

    As all the volunteers in the experiment were relatively young, researchers are still working to look at the effects of light exercise on older people. " Our future goal is to try to develop an exercise prescription (处方)that can be used by older adults who might have disabilities or mobility impairments, but can still adopt very simple exercise rules of life and be able to, perhaps, delay cognitive decline temporarily," said Yassa.

(1)、What did the researchers find from the experiment mentioned in the text?
A、Regular exercise is of benefit to the memory of all people. B、Just a short period of exercise better young people's memory power. C、Older people can also imp rove their cognitive power by exercising regularly. D、AU the volunteers in the experiment imp roved their memory through exercise.
(2)、Why was the memory task quite challenging?
A、The lime to solve the questions was too limited. B、The questions asked by the scientists were loo comp Heated. C、The items to be distinguished were extremely similar. D、The people in the experiment were disabled.
(3)、What's the purpose of the text?
A、To solve a problem. B、To give practical advice. C、To present a research result. D、To tell an interesting story.
(4)、What can be a suitable title for the text?
A、Advantages of Exercising Regularly B、Exercise Is Beneficial to Both Young and Old C、Exercise Can Imp rove Older People's Cognitive Power D、Ten Minutes of Exercise a Day Might Imp rove Memory

根据短文内容的理解,选择正确答案。
    Hey there,
    So you're about to spend four years of your life and tens of thousands of dollars of your parents' money, and all you really know about college is that all of your friends are going. Do you ever stop to wonder why you're going?
    Relax. You're making the right decision. First of all, you'll discover what interests you by taking courses in many subjects. For example, it's hard to decide if you want to be a painter if you've never painted any pictures; once you're in a drawing room on campus, you'll know one way or the other. College is also a lot of fun—after you graduate, you'll be working every weekday for 50 or so years. And remember that college graduates earn about twice the income of those who never attend college.
    Finding the right college can be difficult. Fortunately, Johnson Review is here to help you every step of the way.
    *Researching Schools. To us, the most important decision you'll make is to choose the school that really fits you best—not the one that is the most competitive or has the best equipped rooms.
    *Applying to School. On JohnsonReview.com, you'll find hundreds of actual college applications and links to many more.
    *Raising Your Scores. American College Test is one of the most difficult parts of the admissions course. It's not the most important, though, and not everyone needs to prepare for the test. But, if you think you can do better, find the right course for better scores.
    *Paying for School. Most families need financial aid for the high cost of college. The problem is that financial aid seems difficult to get and many families get caught up in the price of college rather than learning the ways to get financial aid. If you really do your research, you'll learn that you can afford to attend any college, no matter the cost.

    Thanks to this new hands- free suitcase, carrying around heavy luggage may soon become a thing of the past. Designed by Israeli company NUA Robotics, this "smart" suitcase can follow you everywhere you go.

    The carry­on suitcase, now a prototype(雏形), connects to a smartphone app via bluetooth. It has a built­in camera sensor that can "see" you and follow you around on flat floors. It comes with an anti­theft alarm to prevent someone carrying it away when you're not looking. "It can follow and carry things for people around while communicating with their smartphone, and avoiding bumping into other objects," explained Alex Libman, founder of NUA Robotics. "We're combining sensor network, computer vision, and robotics. So if you download our app(应用), press the 'follow me' button, the luggage recognizes its user and knows to follow and communicate."

    NUA is still testing the products and trying to improve features like speed and customization(客户订制), but they hope to make the suitcase available to customers in a year's time. If it proves successful, they want to use the bluetooth pairing technology to automate(自动化操作)lots of other products, like shopping carts at the supermarket. These products are especially meant to be useful to the physically disabled and elderly. "Any object can be smart and robotic," Libman told Mashable. "We want to bring robots into everyday life."

    The Israeli tech company made it clear that the finished product will look just like a common suitcase. They're planning to partner with a carry­on luggage maker, since the product that makes it "smart" weighs just 2.5 pounds and can be fitted on old­fashion luggage.

    With NUA's smart suitcase, carrying around heavy luggage isn't a burden. But how their invention will handle tough blocks like stairs? It will be interesting to wait.

Rick Guidotti put aside his career as a fashion photographer to turn his lens(镜头) to people living with genetic, physical and behavioral differences.

He says what changed his perception(看法) of beauty was a chance encounter with an albino (患白化病的) girl."I was just tired of people telling me who was beautiful. Every season that face would change but I was always told who was beautiful. As an artist, I don't see beauty just on covers of magazines. I see it everywhere. So that was my original intention—that opened my eyes a little wider and wider."

Guidotti has created Positive Exposure, a not-for-profit organization that uses photography and video to transform public perceptions and promote a world where differences are celebrated. Guidotti and Positive Exposure are featured in a new documentary called On Beauty.

One of the women featured in the film is Jayne Waithera. "I never thought I was beautiful because nobody said that to me, but meeting him was my profound moment. I remember that particular day. He took my picture and I felt so good like I felt there's somebody who, like, really loves me and sees me for who I am and who sees me more than my condition."

Guidotti is travelling from city to city to promote On Beauty. He says his tour is not about money; it's about the message. "As I travel from community to community, I'm taking photographs and I'm empowering(给某人……的权力) individuals with a positive sense of who they are. They're seeing beauty in their reflection but I'm also empowering their families and they in turn are empowering their communities as well. All is based on the philosophy of change—how you see, how you change."
