1 . The problem with students using Google is not that the search leader is unable to offer useful educational content. It’s that finding that content using simple search terms is a difficult art to master. But some educational companies and organizations aim to make it easier to find useful educational content among the Web. They are forming a working group to come up with more detailed criteria(标准)that could eventually be added into the search lines for Google, Bing, and Yahoo !
The project was encouraged by a joint move by those major search engines to help users do more effective Websearches. The idea behind the new education corporation is to determine a common “framework” for narrowing search results for education content—by subject area, or source type, or content type, or any number of possible criteria. The goal is also to persuade publishers of educational content to use a matching set of tags(分类)to help the search engines sort out their content more easily.
Search engines are used by college students, but they were not designed for them. This has been a subject of much handwringing (绝望) among professors, who worry that students are not finding the most reliable content on the Internet even if more and more content providers of good fame—textbook publishers, scholars, universities and many others—have been putting useful academic resources on the open Web.
Michael Johnson, a member who will be serving on a working group devoted to developing the framework over the next six months or so, said “The project is aimed at benefiting the publishers of educational content as much as students. ”

3 . Where was I? The room was dark and quiet. My head hurt really badly. I shouted, “Help! Help! Can anybody help me?”
After a while somebody came in. The room was so dark that I could’t see hs face clearly. The man turned on the light and said with a sharp voice, “Ah! Sweetie, do you still remember who I am?” I was shocked. Oh , my God! I cried, “You are Michael Zey, the man I charged with murder! Why are you here? You should be in prison!”
“You never thought about the result of charging a gang(犯罪团伙) leader, did you? Because of you, I was in prison for 15 years. You ruined my life!” His voice was very cold. My face was pale with fear. He was here to take revenge(报复)!
“Please, let me go! Don’t hurt me! Please!” I sked him. “Dr Calment, you are smart enough to know it is impossible. Now, I give you two choices. One is shooting your head. It is the quickest way. The other is cremation(火葬). Your husband and you will be together forever. It’s quite romantic. Don’t you think?” He spoke angrily. “What? My husband? He is innocent!” I shouted at him.
Suddenly, he took hold of my head and said, “you will pay for what you have done to me.” He took out a gun from his bag.
“Help! Help! Can anybody help me?”

4 . A chip inserted in a young quadriplegic’s (四肢麻痹患者) brain is already improving his quality of life. Soon the benefits may be more widespread.
A 25-year-old man unable to move from the neck down recently did what many assumed impossible. After a knife attack that had left him paralyzed, all he could move was his head, which he used to push a switch and call for a nurse. And he could turn his wheelchair by blowing into a straw near his face. That was it.
Then last June, a Foxborough (Mass.) company called Cyber Kinetics opened the man’s skull and inserted a special chip no larger than a baby aspirin. That insert has given him a few additional and precious abilities. When connected to a special computer via a cable, the chip translates the young man’s thoughts into commands that let him move a cursor across a PC screen and open e-mail. He can draw a circle with a computer painting program. And he can use a robotic hook (钩) to perform simple tasks like picking up a candy and sliding it across a table.
All he has to do is to think.
Several new studies have begun or been completed in the past year. In fact, more than half of the scientific papers in this field, called brain-to-computer interaction (BCI), have been published in the past two years, notes Jonathan Wolpaw, a research physician at Wadsworth Center, the New York State Health Dept.’s research laboratory.
Brain surgeries (手术) are no longer rare: Thousands of Parkinson’s disease patients have had special devices inserted in their brains to ease uncontrollable shaking and other symptoms. The inserts themselves have improved, so the body doesn’t reject them as furiously (猛烈地). And significant development has been achieved in software used to interpret the brain’s signals and change them into commands understood by computers.
But increased demand for thought technology remains the biggest reason for the field’s progress. Today, 4 million Americans live with paralysis according to the Christopher Reeve Paralysis Foundation.
Scientists hope that thought technology will reduce the impact of such disabilities. People with spinal-cord injuries, for example, often lose their ability to walk because the communications network between their brain and their legs has been interrupted. The brain still commands the leg muscles to move, but they don’t hear its orders.
Thought technology, scientists hope, will bridge this communications gap. “Our goal is for you to see paralyzed people eating at a restaurant and for you not to know that they are paralyzed,” says John Donoghue, founder and chief scientific officer at Cyber Kinetics.
