Khan lives in Silicon Valley, with his wife, a doctor, and their new baby. He got the idea for his “Khan Academy” four years ago, when he taught a young cousin how to convert kilograms to grams. With Khan’s help, the cousin got good at math, and Khan began a new career.
Now, Khan records his lessons himself, but he never goes on camera. “It feels like my voice in their head. You’re looking at it and it feels like someone’s over your shoulder talking in your ear, as opposed to someone at the blackboard, which is distant from you,” he said.
When Springfield High School in Palo Alto, California invited Khan to speak in person --- he immediately connected to the students there.
The idea of short lessons that can be played over and over again attracted high school senior Bridget Meaney. She says she had trouble with math in the seventh grade. “I think the teachers are good, but they can’t teach at a speed that’s perfect for everyone,” she said. “I like the idea of learning something in class but then going back and pressing pause or rewind and actually getting a deeper understanding of it.”
Originally, Khan kept his lessons short because of YouTube restrictions. Now, he thinks short is better. “Education researchers now tell me that 10 minutes is how long someone can have a high level of concentration. And anything beyond that and your brain switches off,” he said.
For Khan, teaching math, science, and finance is just the beginning. He says he’s ready to expand his YouTube site to include other subjects as well.

“Empty your pockets please, Alfred,” Sam Carr demanded in a firm voice.
Alfred pretended to be shocked but he knew he’d been caught. From his coat he withdrew a make-up kit, a lipstick and two tubes of toothpaste.
“I’m disappointed in you, Alfred!” said the little gray-haired man.
“Sorry, sir. Please forgive me. It’s the first time I’ve ever done such a thing,” Alfred lied, hoping to gain the old man’s sympathy.
Mr Carr’s brow furrowed as he reached for the phone, “Do you take me for a fool? Let’s see what the police have to say. But first I’ll call your mother and let her know her son is heading to jail.”
“Do whatever you want,” Alfred shot back, trying to sound big. But deep down he felt like a child. He imagined his mother rushing in, eyes burning with anger, maybe in tears. Yet he wanted her to come quickly before Mr. Carr called the police.
Mr. Carr was surprised when Mrs Higgins finally arrived. She was very calm, quiet and friendly. “Is Alfred in trouble?” she asked.
“He’s been stealing from the store,” the old man coolly replied.
Mrs. Higgins put out her hand and touched Mr. Carr’s arm with great gentleness as if she knew just how he felt. She spoke as if she did not want to cause him any more trouble. “What do you want to do, Mr. Carr?”
The woman’s calm and gentle manner disarmed the once-angry store-owner. “I was going to get a cop. But I don’t want to be cruel. Tell your son not to come back here again, and I’ll let it go.” Then he warmly shook Mrs. Higgins’s hand.
Mrs. Higgins thanked the old man for his kindness, then mother and son left. They walked along the street in silence. When they arrived home his mother simply said, “Go to bed, you fool.”
In his bedroom, Alfred heard his mother in the kitchen. He felt no shame, only pride in his mother’s actions. “She was smooth!” he thought. He went to the kitchen to tell her how great she was, but was shocked by what he saw.
His mother’s face looked frightened, broken. Not the cool, bright face he saw earlier. Her lips moved nervously. She looked very old. There were tears in her eyes.
This picture of his mother made him want to cry. He felt his youth ending. He saw all the troubles he brought her and the deep lines of worry in her grey face. It seemed to him that this was the first time he had ever really seen his mother.
小题1:Which of the following is true according to the passage?
A.It was the first time Alfred had stolen anything. |
B.Alfred tried to sound big to hide his fear. |
C.Mr. Carr set a trap to catch Alfred stealing. |
D.Mr. Carr had planned to forgive Alfred from the beginning. |
A.annoyed | B.made less angry |
C.convinced | D.got over |
A.She felt disappointed with him. |
B.She was very strict with him. |
C.She was supportive of him. |
D.She was afraid of him. |
A.how angry she was |
B.that she didn’t cry |
C.that she was able to save him |
D.how effectively she handled Mr. Carr |
A.was no longer a youth |
B.felt proud of his mother |
C.wanted his mother to be happy |
D.felt guilty and regretful for his deed |
As her house was not big, she couldn"t practise 48__ in it. So she usually left home, walking and singing 49 the country road. She practised her high notes 50 walking. However, each time she heard a person or a car 51 along the road, she 52 singing. She did not want her high notes to be 53 , for she was shy.
One afternoon a fast open car came up to her so 54 and so fast that she didn"t 55 it until the car was only a few meters. She was practising some of her 56 and most difficult notes at that time. As the car passed by, she saw a 57 expression come over the driver"s face. He stopped suddenly to 58 all the tires (轮胎) carefully.
Mrs. Green felt it shy to tell the driver what the 59 he had heard really was. The driver found 60 wrong, got back into the car and drove off.

Irvine Robbins opened his first ice cream store in 1945 in California.At the time, there were no stores that sold only ice cream.His sister"s husband, Burton Baskin, also opened his own ice cream stores.
