It was a very cold evening. The old man's beard was almost icy. He was waiting for a 1 across the river. The wait seemed 2. The old man sat on the ground waiting for quite a long time.

    3, he saw several horsemen coming. He watched them silently and let the first one pass by without even asking. Another passed by, and then another, till the last rider came near the old man. The old man caught the rider's 4 and said, “Sir, would you 5 giving me a ride to the other side?”

    6 his horse, the rider replied, “Of course not.” But it was so cold that the old man's body was almost 7. He could not get 8the ground. The horseman helped the old man onto his horse. He took the old man not just across the river, 9to the old man's home.

    As they 10 the old man's house, the horseman asked, “Sir, you let several other riders pass by without even asking. Then I 11 and you asked me for a ride at once. Why? 12 I had said 'no' and left you there?”

    The old man looked the rider straight in the eye, and said, “I looked 13 the eyes of the other riders. I quickly saw that they didn't 14. It would be 15 even asking them for a ride. But in your eye I saw 16. I knew that you would help me.”

    The words 17 the rider deeply. “Thank you for what you've said,” he told the old man. “I hope I will never leave others 18 simply because I'm busy, and every American citizen does 19 in my heart.”

    With that, Thomas Jefferson, the third president of the US, turned his horse around and made his 20back to the White House.

When I was young, I was told that I .

a. You'd be how much money you can save.

b. I think you are doing an job with those children.

    As Internet users become more dependent on the Internet to store information, are people remember less? If you know your computer will save information, why store it in your own personal memory, your brain? Experts are wondering if the Internet is changing what we remember and how.

    In a recent study, Professor Betsy Sparrow conducted some experiments. She and her research team wanted to know how the Internet is changing memory. In the first experiment, they gave people 40 unimportant facts to type into a computer. The first group of people understood that the computer would save the information. The second group understood that the computer would not save it. Later, the second group remembered the information better. People in the first group knew they could find the information again, so they did not try to remember it.

    In another experiment, the researchers gave people facts to remember, and told them where to find the information on the Internet. The information was in a specific computer folder(文件夹). Surprisingly, people later remember the folder location(位置) better than the facts. When people use the Internet, they do not remember the information. Rather, they remember how to find it. This is called "transactive memory(交互记忆)".

    According to Sparrow, we are not becoming people with poor memories as a result of the Internet. Instead, computer users are developing stronger transactive memories; that is, people are learning how to organize huge quantities of information so that they are able to access it at a later date. This doesn't mean we are becoming either more or less intelligent, but there is no doubt that the way we use memory is changing.

    Missing friends who live far away? Or just need a little family comfort after a long day? Sometimes you just need a hug. And sometimes there's just no one around to give you one. So what do you do? How about a virtual hug?

    Scientists at the Massachusetts Institute of Technology(MIT)have invented a social media vest(社交背心)that allows people to give hugs to their friends, family and loved ones on Facebook.

    The vest is called Like-A-Hug, which is connected with your Facebook page. Whenever Facebook friends "Like" a photo, video or anything you post on the network, a fan will blow air into the vest to give you a hug. Hugs can also be sent back to the sender by pressing the vest to lose air, according to the website of designer Melissa Chow.

    She worked with Andy Payne and Phil Seaton at the MIT Media Lab to build the black vest, making the wearer "feel the warmth, encouragement, support, or love that we feel when we receive hugs." Melissa Chow said, "We came up with the idea over a free talk about long-distance relationships and the shortcomings of video chat interfaces(视频聊天界面)like Skype. "

    Chow and her workmates finished work on the vest, and it has drawn the attention of the public.

    Chow provided no pricing or ordering information for the Like-A-Hug vest, so don't expect to see people blowing up all over town just yet.

    Although researchers believe that Like-A-Hug will cause a worldwide storm, a lot of people think it can't take the place of the feeling of a real hug. Body temperature or the taste of hair and so on is far from what a social vest can match.

    In a time when ivory poaching(偷猎)has gotten so bad that it threatens to wipe out several animal species, a young Dutch designer is creating "egalitarian(平等主义)jewelry" made of our very own ivory—teeth.

    Lucie Majerus got the idea for her "human ivory" collection after having her wisdom teeth removed. She kept them and soon realized they would make great material for a jewelry collection. "Why wouldn't we value our own material instead of the precious material from other species? And what if we mine our own ivory and turn it into pearls?" she asks.

    Her own teeth became a ring, but in order to create a whole collection, she needed more material, and since having more of her teeth removed wasn't a very pleasant choice, she asked her dentist to save his patients' unwanted teeth. Most people choose not to keep their pulled teeth, so they are usually donated to dentistry schools. Majerus also received the lost teeth of two of her teachers at Design Academy Eindhoven, so she had a nice supply of human ivory to experiment with.

    To turn human teeth into attractive pieces of jewelry, Lucie Majerus first bleaches(漂白)them, and then uses a stone polishing machine to shape the teeth into various shapes.

    Majerus displayed her human ivory jewelry collection at this year's Dutch Design Week, and claims that people's reaction was mostly positive." Surprisingly, most people aren't frightened at the sight of the jewelry, but really like the idea, "Majerus told Fast Co Design." Some regret that they didn't keep their tooth at the dentist and some, who will have teeth taken out soon, are now looking forward to it. "
