Once when I was facing a decision that involved high risk, I went to a friend. He looked at me for a moment, and then wrote a sentence containing the best advice I’ve ever had: Be bold and brave — and mighty (强大的) forces will come to your aid.
Those words made me see clearly that when I had fallen short in the past, it was seldom because I had tried and failed. It was usually because I had let fear of failure stop me from trying at all. On the other hand, whenever I had plunged into deep water, forced by courage or circumstance, I had always been able to swim until I got my feet on the ground again.
Boldness means a decision to bite off more than you can eat. And there is nothing mysterious about the mighty forces. They are potential powers we possess: energy, skill, sound judgment, creative ideas — even physical strength greater than most of us realize.
Admittedly, those mighty forces are spiritual ones. But they are more important than physical ones. A college classmate of mine, Tim, was an excellent football player, even though he weighed much less than the average player. “In one game I suddenly found myself confronting a huge player, who had nothing but me between him and our goal line,” said Tim. “I was so frightened that I closed my eyes and desperately threw myself at that guy like a bullet（子弹） — and stopped him cold.”
Boldness — a willingness to extend yourself to the extreme—is not one that can be acquired overnight. But it can be taught to children and developed in adults. Confidence builds up. Surely, there will be setbacks (挫折) and disappointments in life; boldness in itself is no guarantee of success. But the person who tries to do something and fails is a lot better off than the person who tries to do nothing and succeeds.
So, always try to live a little bit beyond your abilities—and you’ll find your abilities are greater than you ever dreamed.Why was the author sometimes unable to reach his goal in the past?

One day when I was 12, my mother gave me an order: I was to walk to the public library, and borrow at least one book for the summer. This was one more weapon for her to defeat my strange problem - inability to read.
In the library, I found my way into the "Children's Room." I sat down on the floor and pulled a few books off the shelf at random. The cover of a book caught my eye. It presented a picture of a beagle. I had recently had a beagle, the first and only animal companion I ever had as a child. He was my secret sharer, but one morning, he was gone, given away to someone who had the space and the money to care for him. I never forgot my beagle.
There on the book's cover was a beagle which looked identical（相同的） to my dog. I ran my fingers over the picture of the dog on the cover. My eyes ran across the title, Amos, the Beagle with a Plan. Unknowingly, I had read the title. Without opening the book, I borrowed it from the library for the summer.
Under the shade of a bush, I started to read about Amos. I read very, very slowly with difficulty. Though pages were turned slowly, I got the main idea of the story about a dog who, like mine, had been separated from his family and who finally found his way back home. That dog was my dog, and I was the little boy in the book. At the end of the story, my mind continued the final scene of reunion, on and on, until my own lost dog and I were, in my mind, running together.
My mother's call returned me to the real world. I suddenly realized something: I had read a book, and I had loved reading that book. Everyone knew I could not read. But I had read it. Books could be incredibly wonderful and I was going to read them.
I never told my mother about my "miraculous" (奇迹般地) experience that summer, but she saw a slow but remarkable improvement in my classroom performance during the next year. And years later, she was proud that her son had read thousands of books, was awarded a PhD in literature, and authored his own books, articles, poetry and fiction. The power of the words has held.

Whether in the home or the workplace, social robots are going to become a lot more common in the next few years. Social robots are about to bring technology to the everyday world in a more humanized way, said Cynthia Breazeal, chief scientist at the robot company Jibo.
While household robots today do the normal housework, social robots will be much more like companions than mere tools. For example, these robots will be able to distinguish when someone is happy or sad. This allows them to respond more appropriately to the user.
The Jibo robot, arranged to ship later this year, is designed to be a personalized assistant. You can talk to the robot, ask it questions, and make requests for it to perform different tasks. The robot doesn’t just deliver general answers to questions; it responds based on what it learns about each individual in the household. It can do things such as reminding an elderly family member to take medicine or taking family photos.
Social robots are not just finding their way into the home. They have potential applications in everything from education to health care and are already finding their way into some of these spaces.
Fellow Robots is one company bringing social robots to the market. The company’s “Oshbot” robot is built to assist customers in a store, which can help the customers find items and help guide them to the product’s location in the store. It can also speak different languages and make recommendations for different items based on what the customer is shopping for.
The more interaction the robot has with humans, the more it learns. But Oshbot, like other social robots, is not intended to replace workers, but to work alongside other employees. “We have technologies to train social robots to do things not for us, but with us,” said Breazeal.How are social robots different from household robots?
| A．They can control their emotions. |
| B．They are more like humans. |
| C．They do the normal housework. |
| D．They respond to users more slowly. |
What can a Jibo robot do according to Paragraph 3?
| A．Communicate with you and perform operations. |
| B．Answer your questions and make requests. |
| C．Take your family pictures and deliver milk. |
| D．Obey your orders and remind you to take pills. |
What can Oshbot work as?
| A．A language teacher. | B．A tour guide. |
| C．A shop assistant. | D．A private nurse. |

| A．train employees |
| B．be our workmates |
| C．improve technologies |
| D．take the place of workers |
What does the passage mainly present?
| A．A new design idea of household robots. |

No one is sure how the ancient Egyptians built the pyramids near Cairo. But a new study suggests they used a little rock‘n’roll. Long-ago builders could have attached wooden pole s to the stones and rolled then across the sand, the scientists say.
“Technically, I think what they’re proposing is possible,” physicist Daniel Bonn said.
People have long puzzled over how the Egyptians moved such huge rocks. And there’s no obvious answer. On average, each of the two million big stones weighed about as much as a large pickup truck. The Egyptians somehow moved the stone blocks to the pyramid site from about one kilometer away.
The most popular view is that Egyptian workers slid the blocks along smooth paths. Many scientists suspect workers first would have put the blocks on sleds(滑板). Then they would have dragged them along paths. To make the work easier, workers may have lubricated the paths either with wet clay or with the fat from cattle. Bonn has now tested this idea by building small sleds and dragging heavy objects over sand.
Evidence from the sand supports this idea. Researchers found small amounts of fat, as well as a large amount of stone and the remains of paths.
However, physicist Joseph West thinks there might have been a simpler way , who led the new study . West said , “I was inspired while watching a television program showing how sleds might have helped with pyramid construction . I thought , ‘Why don’t they just try rolling the things?’“A square could be turned into a rough sort of wheel by attaching wooden poles to its sides , he realized . That , he notes , should make a block of stone” a lot easier to roll than a square”.
So he tried it.
He and his students tied some poles to each of four sides of a 30-kilogram stone block. That action turned the block into somewhat a wheel. Then they placed the block on the ground.
They wrapped one end of a rope around the block and pulled. The researchers found they could easily roll the block along different kinds of paths. They calculated that rolling the block required about as much force as moving it along a slippery(滑的)path.
West hasn’t tested his idea on larger blocks, but he thinks rolling has clear advantages over sliding. At least, workers wouldn’t have needed to carry cattle fat or water to smooth the paths.It’s widely believed that the stone blocks were moved to the pyramid site by ______.
| A．rolling them on roads |
| B．pushing them over the sand |
| C．sliding them on smooth paths |
| D．dragging them on some poles |
The underlined part “lubricated the paths” in Paragraph 4 means____.
| A．made the path wet |
| B．made the path hard |
| C．made the path wide |
| D．made the path slippery |
What does the underlined word “it”in Paragraph 7 refer to?
| A．Rolling the blocks with poles attached. |
| B．Rolling the blocks on wooden wheels. |
| C．Rolling poles to move the blocks. |
| D．Rolling the blocks with fat. |
Why is rolling better than sliding according to West ?
| A．Because more force is needed for sliding. |
| B．Because rolling work can be done by fewer cattle. |
| C．Because sliding on smooth road is more dangerous. |
| D．Because less preparation on path is needed for rolling. |
What is the text mainly about ?
| A．An experiment on ways of moving blocks to the pyramid site. |
| B．An application of the method of moving blocks to the pyramid site. |
| C．An argument about different methods of moving blocks to the pyramid site. |
| D．An introduction to a possible new way of moving blocks to the pyramid site. |
