Q: There are stories about two US Presidents,Andrew Jackson and Martin Van Buren,which attempt to explain the American English term OK. We don't know if either story is true,but they are both interesting.

The first explanation is based on the fact that President Jackson had very little education. In fact,he had difficulty reading and writing. When important papers came to Jackson,he tried to read them and then had his assistants explain what they said. If he approved of a paper, he would write "all correct" on it. The problem was that he didn't know how to spell. So what he really wrote was "ol korekt". After a while,he shortened that term to "OK".

The second explanation is based on the place where President Van Buren was born,Kinderhook,New York. Van Buren's friends organized a club to help him become president. They called the club the Old Kinderhook Club,and anyone who supported Van Buren was called "OK".

Answer the following questions:
1. What two men are mentioned in this story?
2. What degree did Jackson earn?
3. How many theories are explained here?
A: 1. US Presidents
2. None, President Jackson had very little education
3. Two
Q: Since the 1970s, scientists have been searching for ways to connect the brain with computers. Braincomputer interface(BCI) technology could help people with disabilities send commands to machines. Recently, two scientists, Jose Millan and Michele Tavella from the Federal Polytehnic School in Lausanne, Switzerland, show a small robotic wheelchair directed by a person's thoughts. In the laboratory, Tavella operated the wheelchair just by thinking about moving his left or right hand. He could even talk as he watched the vehicle and guided it with his thoughts. "Our brain has billions of body cells . These send signals through the spinal cord to the body part to give us the ability to move. But spinal cord injuries or other conditions can prevent these weak electrical signals from reaching the body part." Tavella says. "Our system allows disabled people to communicate with outer world and also to control machines." The scientists designed a special cap for the user. This head cover picks up the signals from the scalp and sends them to a computer. The computer finds meanings of the signals and commands the wheelchair with an engine. The wheelchair also has two cameras that tell objects in its path. They help the computer react to commands from the brain. Prof. Millan , the team leader, says scientists keep improving the computer software that finds meanings of brain signals and turns them into simple commands." The practical possibilities that BCI technology offers to disabled people can be grouped in two kinds: communication, and controlling objects. One example is this wheelchair." He says his team has set two goals. One is testing with real patients, so as to prove that this is a technology they can get advantages from. And the other is sure that they can use the technology for long.

Q: CHAPTER X

They were gone. Carl was full of the nauseating shame which a matter-of-fact man, who supposes that he is never pilloried, knows when a conscientious friend informs him that he has been observed, criticized; that his enthusiasms have been regarded as eccentricities; his affectionate approaches toward friendship as impertinence.

There seemed to be hundreds of people in the room, nudging one another, waiting agape for him to do something idiotic; a well-advertised fool on parade. He stalked about, now shamefaced, now bursting out with a belligerent, "Aw, rats! I'll show 'em!" now plaintively beseeching, "I don't suppose I am helping Frazer, but it makes me so darn sore when nobody stands up for him--and he teaches stuff they need so much here. Gee! I'm coming to think this is a pretty rough-neck college. He's the first teacher I ever got anything out of--and----Oh, hang it! what 'd I have to get mixed up in all this for, when I was getting along so good? And if it isn't going to help him----"

His right hand became conscious of Gertie's letter crumpled in his pocket. As turning the letter over and over gave him surprisingly small knowledge of its contents, he opened it:

DEAR CARL,--You are just _silly_ to tease me about any bank clerk. I don't like him any more at all and he can go with Linda all he likes, much I care!

We are enjoying good health, though it is getting quite cold now and we have the furnace running now and it feels pretty good to have it. We had _such_ a good time at Adelaide's party she wore such a pretty dress. She flirted terribly with Joe Jordan though of course you'll call me a cat for telling you because you like her so much better than me & all.

Answer the following questions:
1. Which emotion was Carl feeling?
2. How had his tries at friendship been taken?
