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 You Tube —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. |

Swimming is one of those activities that can be learned early in life. Little children can learn to swim as soon as they walk. In fact, you need the same skills in walking as in swimming. However, I believe that five is the best age to learn. By five or six, a child knows fear of water, a very important thing to know. It’s wise to be afraid, to recognize true danger. Young ones understand that the water can sometimes be very dangerous.
To really benefit from swimming, every swimmer should learn ____________：butterfly, backstroke, breaststroke, and crawl. I feel that one of these—the breaststroke—is different from the others, since some young swimmers use this stroke naturally, without any training.
In swimming, there are certain rules every swimmer should follow:
(1) Never swim alone! No matter how good you are in the water, don’t risk drowning by swimming alone. If you swim by yourself, with no life guards or friends with you, you may get into trouble.
(2) Don’t go beyond your abilities. Most swimmers know enough not to swim too far from the bank or the beach. Showing off by doing dangerous tricks is no good. Swim safely and you will continue to swim and alive.
(3) Don’t smoke. Swimming depends on a healthy body; good lungs are part of it.
(4) Work at any activity that builds muscles.What is the main idea of the passage? (no more than 10 words)

When people hear that I’m the youngest person to row solo across the Atlantic Ocean, they all have the same question: How did a 22-year old woman row a 19-foot boat for 70 days through high winds and crashing waves? Well, the biggest difficulty for me wasn’t physical. By the time I decided to do the ocean row, I had already biked 3,300 miles cross-country, run across the Mojave Desert, and swum the 325-mile length of the Allegheny River. No, the tough part would be mental: How would I handle the loneliness, the boredom of the vast sea?
I set off on January 3, 2010. I set my sights on getting past the quarter-way mark, which would take about 20 days.
Day 20, January 22, was gray and cloudy. I could have done something to celebrate, such as treating myself to a chocolate bar. But I didn’t.
I was suffering from terrible loneliness. I hadn’t seen landing over two weeks. Every day was beginning to feel the same. Eating, rowing, sleeping, watch the sky, watch the ocean.
Then, around sunset, I saw something move on the horizon. They were dolphins! They circled my boat. Suddenly I felt so grateful. They had come to help me celebrate, just when I needed them. I rowed at full strength for the next 20 minutes with the dolphins around. By the time we went our separate ways, I was no longer lonely. Better yet, I knew I would be okay.
I did make it, all 2,817 miles. I hit the coast of Guyana, South America, on March 14, after 70 days and five hours at sea. My ocean row raised $70,000 for the Blue Planet Run Foundation, which funds drinking water programs around the world. I know some athletes spend the entire journey imagining the end, and that helps them get through. But for me, the secret is to focus on the moment, where you experience the personal growth — those moments of awareness of being connected to the sun, the weather, and the waves. And, on the best day of my life, those dolphins, which freed myself from terrible loneliness.Which is the step taken as part of preparation for the tough row?
| A．swimming the 325-mile length of the river |
| B．answering the same question raised by people |
| C．running 3,300 miles cross-country |
| D．biking across the Mojave Desert |
What does the underlined part mean?
| A．I didn’t have any chocolate bar for energy. |
| B．I wasn’t in the mood to celebrate my first goal. |
| C．It’s a pity not to celebrate my passing the quarter of the way |
| D．It’s a pity not to treat myself to a chocolate bar on Day 20. |
What can be implied from the last two paragraphs?
| A．Imagination was an effective way to help me get through. |
| B．The Blue Planet Run Foundation helped me a lot. |
| C．The dolphins accompanied me to reach my destination |
| D．The unexpected dolphins swept away my loneliness |
Which can be the best title of the passage?
| A．The day I stopped being lonely |
| B．The only challenge for a 22-year old |
| C．How to overcome loneliness at sea. |
| D．How to row alone across the Atlantic |
Do you want to live forever? By the year 2050, you might actually get your wish — if you are willing to leave your biological body and live in silicon circuits （半导体电路）．But long before then, perhaps as early as 2020, some measures will begin offering a semblance of immortality （虚拟的永生）.
Researchers are confident that technology will soon be able to track every waking moment of your life. Whatever you see and hear, all that you say and write, can be recorded, analyzed and added to your personal chronicles （履历）. By the year 2030, it may be possible to catch your nervous systems through electrical activities, which would also keep your thoughts and emotions.
Researchers at the laboratories of British Telecommunications have given the name of this idea as Soul Catcher. Small electronic equipment will make preparation for Soul Catcher. It would use a wearable supercomputer, perhaps in a wristwatch, with wireless links to micro sensors under your scalp（头皮） and in the nerves that carry all five sensory signals. So wearing a video camera would no longer be required.
At first, the Soul Catcher's companion system — the Soul Reader — might have trouble copying your thoughts in complete details. Even in 2030, we may still be struggling to understand how the brain is working inside, so reading your thoughts and understanding your emotions might not be possible. But these signals could be kept for the day when they can be transferred to silicon circuits to revitalize minds everlasting entities （永生实体）. Researchers can only wonder what it will be like to wake up one day and find yourself alive inside a machine．
For people who choose not to live in silicon, semblance of immortality would not be as useless as they thought. People would know their lives would not be forgotten, but would be kept a record of the human race forever. And future generations would have a much fuller understanding of the past. History would not be controlled by just the rich and powerful, Hollywood stars, and a few thinkers in the upper society. The main idea of this passage is that _______．
| A．human beings long for living forever |
| B．there are many difficulties in making the Soul Catcher |
| C．people might live forever as technology develops |
| D．the invention of Soul Catcher has great importance |
According to this passage, a Soul Catcher will be ______．
| A．a new machine on which research measures have already been made |
| B．a new invention in order to catch and keep human's thoughts and emotions |
| C．made by British scientists to offer something that looks like living forever |
| D．made of silicon circuits which can catch people's nervous activity |
According to the writer, semblance of immortality is ______．
| A．to be a reality sooner or later | B．far from certain |
| C．just an idea that couldn't t be realized at all | D．a fading hope |

Puerto Rico may be part of the USA but its music and dance is a mixture of both Spanish and African rhythms. The country, as a result, is a mixture of very new and very old. It exhibits the open American way of yet retains the more formal Spanish influences. This is reflected in the architecture, not just the contrast between the colonial and the modern in urban areas but also in the countryside, where older buildings sit side by side with concrete schools and buildings.
However, if you do not wander beyond the tourist areas on the coast, you will not experience the real Puerto Rico. Old volcanic mountains, long inactive, occupy a large part of the interior（内陆）, with the highest peak, Cerro de Punta, at 1,338m in the Cordillera Central. North of the Cordillera is the karst （岩溶）country where the limestone（石灰石）has been acted upon by water to produce a series of small steep hills and deep holes. The mountains are surrounded by a coastal plain with the Atlantic shore beaches cooled all the year round by trade winds.
The population is 3.8 million, of which about 1.5 million live in San Juan, although about another two million Puerto Ricans live in the USA Average life expectancy is 73.8 years and GDP per capita is US $12,212, the highest in Latin America, although not up to the level of mainland USA. Most Puerto Ricans do not speak English and less than 30% speak it fluently. Second generation Puerto Ricans who were born in New York but who have returned to the island, are called Nuyoricans. The people are very friendly and hospitable but there is crime, liked to drugs and unemployment.What are the disadvantages of Puerto Rico?
| A．Too many Puerto Ricans live in the USA |
| B．Few people in Puerto Rico can speak English |

One girl decided to study judo(柔道) although she had lost her left arm in a car accident.
The girl began lessons with an old Japanese judo instructor. The girl was doing well. So she couldn’t understand why, after three months of training, the instructor had taught her only one move.
“Instructor,” the girl finally said, “Shouldn’t I be learning more moves?”
“This is the only move you know, but this is the only move you’ll ever need to know,” the instructor replied.
Not quite understanding, but believing in her teacher, the girl kept training.
Several months later, the instructor took the girl to her first tournament. Surprising herself, the girl easily won her first two matches. The third match proved to be more difficult, but after some time, her opponent became impatient and charged. The girl skillfully used her one move to win the match. Still amazed by her success, the girl was now in the finals.
This time, her opponent was bigger, stronger and more experienced. For a while, the girl appeared to be overmatched. Concerned that the girl might get hurt, the referee called a time-out. She was about to stop the match when the instructor intervened(干预).
“No,” the instructor insisted, “Let her continue.”
Soon after the match restarted, her opponent made a serious mistake: she dropped her guard. Instantly, the girl used her move to pin her opponent. The girl had won the match and the tournament. She was the champion.
On the way home, the girl and her teacher reviewed every move in each and every match. Then the girl gathered the courage to ask what was really on her mind.
“Instructor, how did I win the tournament with only one move?”
“You won for two reasons,” the teacher answered. “First, you’ve almost mastered one of the most difficult throws in all of judo. Second, the only known defense for that move is for your opponent to grab your left arm.”
The girl’s biggest weakness had become her biggest strength.What can we learn about the girl?
