A 33-year-old financial analyst in California recently quit his job to devote himself to an unpaid job teaching math on the Internet, and his lessons are reaching almost 100,000 people a month. Salman Khan’s voice is heard every day on the net --- by tens of thousands of students around the world who are hungry for help learning math. He has posted 1,200 lessons on YouTube ... lessons that appear on an electronic blackboard, which range from basic addition to advanced mathematics for science and finance. And they are free.

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.

What gave Khan the idea of teaching math online?

A. His success in helping his cousin learn math.

B. His discovery that many students found learning math difficult.

C. A suggestion made to him at a local high school.

D. His interest in Internet teaching.

Why does Khan never go on camera?

A. He’s too shy to show his face on camera.

B. It’s restricted by YouTube for education videos.

C. He wants to keep distance from the viewers.

D. He wants to create a more relaxed learning atmosphere.

From the passage, we know that ________.

A. Khan travels to many schools to promote his lessons

B. Khan plans to include more subjects in the future

C. Khan gives live math lessons every day for free

D. Khan set up the Khan Academy with his wife

Why does Bridget Meaney like Khan’s lessons?

   A. Khan teaches seventh grade math better than her teacher.

   B. The lessons can be watched repeatedly until fully understood.

   C. She can perfectly follow the pace of Khan’s teaching.

   D. She cannot concentrate when learning in class.

What does Khan mean by “short is better” in the 6th paragraph?

   A. Keeping the lessons short can ensure better concentration.

   B. YouTube recommends short lessons for its site.

   C. Short lessons encourage students to return to the website.

   D. Students enjoy short mathematics lessons more.

For almost 18 years, my mom has given time from her life to devote her care to my growth. She has ashed  36  clothes. She’s planned doctors’ appointments  37  all parts of the body, cut hair, taken icures, bought presents,  38 vacations and basically kept a small boy’s life  39  smoothly.
When I was 12, I got into  40  arguments with my older and wiser parents. The   41 never led a any achievement for me, but I still took part. Many times strong feeling of anger caused tears  42  to in my eyes by the end of the quarrel with them.   43 , I’d return to my room and stay for as long as my parents allowed. Then I’d  44  a knock and hardly manage a weak, “Come in.” My mom, acting as a peacemaker,   45  slowly enter and sit next to me on the bed. I’d again try to  46  what I had said was true,  47  this time less angrily. Then mom calmly, strictly and lovingly showed to me her voice of   48  . After that she’d hug me and I’d stop crying; all would be  49  in my family again.
Hugs will  50  be her trademark(標(biāo)志): warm hugs for goodnights, good-byes and a thousand other such situations. “You’re never too old to  51  your mother.” I’ve heard those eight words since I came to the world. They ring true. For some reason, those words possess the unbelievable  52  to reduce anxiety, cool an angry head,   53  fears and put wrong things right.
Perhaps my mother, now worthy of the title “Mom” can  be an example to mothers everywhere. Being a mother is not so  54  . Any female has the ability to become one. The challenge isn’t in becoming a “mother”, but instead , a “mom”. Mine does that quite  55 .

For a small but increasing  number of young women in modern-day China, true love is all about the numbers. A potential suitor may have a good sense of humor and reasonable good looks, but what they say really matters is if he owns an apartment and how many square feet it is. A sizable bank account is also a must, and, some say, so is a luxury car。
At least, that’s the way things look if you watch Chinese television these days. The latest reality-TV scandal to shock the nation involves Ma Nuo, a 22-year-old model from Beijing who appeared on China's most popular dating show, If You Are the One. She rejected an offer from a male contestant to take a ride on his bike. "I'd rather cry in a BMW (寶馬) car than laugh on the backseat of a bicycle," Ma told her suitor with a giggle.
The televised words swept the Internet and made an instant celebrity of Ma, who becomes one of the most talked-about women in the country. The reaction  among young Chinese was especially severe, reflecting growing anxieties over the widening gap between rich and poor, shifting societal values and public attention on the difficulties of finding a mate in a country where men are expected to outnumber women by 24 million in a decade.
As disgusted as they have been by some of the contestants, viewers continue to watch religiously. Why are people still tuning in? "Audiences like programs because they are honest. They show the current reality of Chinese society," says Yan Mu, one of the founders of Baihe.com. Young people are so focused on making money and building their careers these days, they have little time to devote to dating, he says. "Many people feel pressure from their parents and peers," Yan adds. " It can be a struggle to find a partner." Money may not buy you love. But on China's reality shows, it can at least get you a date.
【小題1】The underlined words“numbers”in the first paragraph include the following except_______

A.the age and degreeB.the size of the houseC.the sum of the depositD.the price of the belonging
【小題2】What does Ma Nuo mean by saying“I’d rather cry in a BMW car than laugh on the backseat of a bicycle.”in the second paragraph?
A.When she is in a BMW car, she will cryB.When she is on a bike, she will laugh
C.She prefers money to true loveD.She prefers true love to money
【小題3】Why do many young men take part in TV dating shows?
A.because they think they may get true love from them
B.because they think China’s reality shows can at least give them a chance to date
C.because their parents and peers force them to do so
D.because viewers like dating shows
【小題4】Which one of the following statements is TRUE according to the passage?
A.some contestants have been disgusted because they are dishonest
B.young people are too busy to take part in dating shows
C.some people are worried that societal value are changing
D.Ma Nuo rejected the bike offered by the contestant
【小題5】What is the best title of the passage?
A.China’s TV Dating ShowB.Date for Love or money
C.Date Makes You a CelebrityD.Popular TV Dating Show

Ever since I was little I loved doing things for other people. As I got older I began doing random ( 隨意的 ) things for people. For example, during holidays, such as Christmas, I would make an extra   21  along with the ones for my relatives. Then I would go and find someone in the grocery store and just hand it to them and walk away. It was so much fun. I admit,   22 , the first time I did it I was so   23 . I didn’t know who to give the card to. So I said a little prayer and knew that the   24  person would just appear. About that time an elderly man ran   25  me with his shopping cart. It was an accident, and he   26  a million times. We smiled and he walked away, and I knew that he was the one.  Later I found him in a different isle(過道), handed him the card, and smiled. I said Happy Holidays, and then walked away. It was so great, and the   27  I had afterwards was unexplainable.

Then one day I came across your website (the coolest website ever) and   28  some Smile Cards. When they came in, I started a new project. When I go into a store, I locate a person who I think needs a   29 . Then, I buy a flower, a carnation, to be exact, and   30  it in the most beautiful paper they have. I tie lots of ribbons on it to make it   31 , and then slip the smile card into an envelope and   32  it to the flower. After that, I pay for it and explain to the cashier   33  it is to go to (I live in a pretty small town so it’s easy to get the help of the cashiers). They then give it to that person when they come through.. Once in a while I’ll buy the flower and then just leave it for the cashier. That gets smiles.

My favorite time was when I picked out this elderly woman who was walking around the   34  somewhat confused. I had come across her numerous times and she only smiled slightly once. When she came to the check out (I was watching from outside) her face   35  and the smile was the biggest I had ever seen. Later that week the cashier whom I had had   36  me told me that the lady had been so surprised and while she was walking out with the grocery bag to her car, she was planning what she was going to do for someone else. It was awesome.

I absolutely love the random acts of kindness cards. I   37  at least two in my purse and others in my car, locker and everywhere I go. As I mentioned, my club, STARS, is doing a Random Acts of Kindness Project with the smile cards so they also are using them. I look forward to hearing about their success. It’s really great. I   38  used them in school. I bought my entire math class cans of pop after lunch one day. They came in from lunch and a can of pop and a smile card were setting   39  that day. It totally lightened the mood in the class that day   40  we were studying for a test. Thank you for all of the help that you provide. The smile cards are a great program that brings smiles into the lives of many!
