Sometimes just when we need the power of miracles to change our beliefs， they materialize in the places we’d least expect. They can come to us as a drastic alteration in our physical reality or as a simple synchronicity in our lives. Sometimes they’re big and can’t be missed Other times they’re so subtle that if we aren’t aware， we may miss them altogether. They can come from the lips of a stranger we suddenly and mysteriously encounter at just the right instant. If we listen carefully, we’ll always hear the right words，at the right time， to dazzle us into a realization of something that we may have failed to notice only moments before.
On a cold January afternoon in 1989，I was hiking up the trail that leads to the top of Egypt’s Mt. Horeb. I’d spent the day at St. Catherine’s Monastery and wanted to get to the peak by sunset to see the valley below. As I was winding up the narrow path，I’d occasionally see other hikers who were coming down from a day on the mountain. While they would generally pass with simply a nod or a greeting in another language，there was one man that day who did neither.
I saw him coming from the last switchback on the trail that led to the backside of the mountain. As he got closer，I could see that he was dressed differently from the other hikers I’d seen. Rather than the high-tech fabrics and styles that had been the norm，this man was wearing traditional Egyptian clothing. He wore a tattered， rust-colored galabia and obviously old and thick-soled sandals that were covered in dust. What made his appearance so odd，though，was that the man didn’t even appear to be Egyptian！ He was a small-framed Asian man, had very little hair，and was wearing round，wire-rimmed glasses.
As we neared one another，I was the first to speak.“Hello，”I said，stopping on the trail for a moment to catch my breath. Not a sound came from the man as he walked closer. I thought that maybe he hadn’t heard me or the wind had carried my voice away from him in another direction. Suddenly he stopped directly in front of me on the high side of the trail， looked up from the ground， and spoke a single sentence to me in English，“Sometimes you don’t know what you have lost until you’ve lost it.”As I took in what I had just heard，he simply stepped around me and continued his descent down the trail.
That moment in my life was a small miracle. The reason is less about what the man said and more about the timing and the context. The year was 1989，and the Cold War was drawing to a close. What the man on the trail couldn’t have known is that it was during my Egyptian pilgrimage， and specifically during my hike to the top of Moses’s mountain，that I’d set the time aside to make decisions that would affect my career in the defense industry，my friends，my family，and，ultimately，my life.
I had to ask myself what the chances were of an Asian man dressed in an Egyptian galabia coming down from the top of this historic mountain just when I was walking up，stopping before me，and offering his wisdom，seemingly from out of nowhere. My answer to my own question was easy： the odds were slim to none！ In an encounter that lasted less than two minutes on a mountain halfway around the world from my home， a total stranger had brought clarity， and the hint of a warning， regarding the huge changes that I would make within a matter of days. In my way of thinking，that’s a miracle.
I suspect that we all experience small miracles in our lives every day. Sometimes we have the wisdom and the courage to recognize them for what they are. In the moments when we don’t，that’s okay as well. It seems that our miracles have a way of coming back to us again and again. And each time they do，they become a little less subtle，until we can’t possibly miss the message that they bring to our lives！
The key is that they’re everywhere and occur every day for different reasons， in response to the different needs that we may have in the moment. Our job may be less about questioning the extraordinary things that happen in our daily lives and more about accepting the gifts they bring.Why did the author make a pilgrimage to Mt. Horeb in Egypt?

Young adult filmmakers all hope to show their works in international festivals like Sundance and Toronto. But what about really young filmmakers who aren’t in film school yet and aren’t, strictly speaking, eve adults?
They are at the heart of Wingspan Arts Film Festival tomorrow, in a setting any director might envy: Lincoln center. Complete with “red carpet” interviews and various awards, the festival has much in common with events for more experienced moviemakers, except for the age of the participants: about 8 to 18.
“What’s really exciting is that it’s film for kids by kids,” said Cori Gardner, managing director of Wingspan Arts, a nonprofit organization offering youth arts programs in the New York area. This year the festival will include films not only from Wingspan but also from other city organizations and one from a middle school in Arlington, Virginia. “We want to make this a national event,” Ms. Gardner added.
The nine shorts to b shown range from a Claymation biography of B.B. King to a science fiction adventure set in the year 3005. “Ａlot of the material is really mature,” Ms. Gardner said, talking about films by the New York branch of Global Action Project, a media arts and leadership-training group. “The choice is about the history of a family and Master Anti-Smoker is about the dangers of secondhand smoke.” Dream of the Invisibles describes young immigrants’ (移民) feelings of both belonging and not belonging in their adopted country.
The festival will end with an open reception at which other films will be shown. These include a music video and a full-length film whose title is Pressure. Wingspan Arts Kids Film Festival _____________.

A team of engineers at Harvard University has been inspired by Nature to create the first robotic fly. The mechanical fly has become a platform for a series of new high-tech integrated systems. Designed to do what a fly does naturally, the tiny machine is the size of a fat housefly. Its mini wings allow it to stay in the air and perform controlled flight tasks.
“It’s extremely important for us to think about this as a whole system and not just the sum of a bunch of individual components (元件),” said Robert Wood, the Harvard engineering professor who has been working on the robotic fly project for over a decade. A few years ago, his team got the go-ahead to start piecing together the components. “The added difficulty with a project like this is that actually none of those components are off the shelf and so we have to develop them all on our own,” he said.
They engineered a series of systems to start and drive the robotic fly. “The seemingly simple system which just moves the wings has a number of interdependencies on the individual components, each of which individually has to perform well, but then has to be matched well to everything it’s connected to,” said Wood. The flight device was built into a set of power, computation, sensing and control systems. Wood says the success of the project proves that the flying robot with these tiny components can be built and manufactured.
While this first robotic flyer is linked to a small, off-board power source, the goal is eventually to equip it with a built-in power source, so that it might someday perform data-gathering work at rescue sites, in farmers’ fields or on the battlefield. “Basically it should be able to take off, land and fly around,” he said.
Wood says the design offers a new way to study flight mechanics and control at insect-scale. Yet, the power, sensing and computation technologies on board could have much broader applications. “You can start thinking about using them to answer open scientific questions, you know, to study biology in ways that would be difficult with the animals, but using these robots instead,” he said. “So there are a lot of technologies and open interesting scientific questions that are really what drives us on a day to day basis.” The difficulty the team of engineers met with while making the robotic fly was that __________.
| A．they had no model in their mind |
| B．they did not have sufficient time |
| C．they had no ready-made components |
| D．they could not assemble the components |

Have you ever looked toward the sky on a fall day and witnessed a group of migrating birds? If so, you probably noted the V-shaped formation of the birds or the birds flying in a ball-like formation. Why do birds fly this way? Many theories have been developed to explain the formation patterns of different types of birds.
One theory is that birds fly in certain formations to take advantage of the laws of nature. The birds know that flying in a V-shaped pattern will save energy. Like the lead cyclist in a race who decreases wind force for the cyclists who follow, the lead bird cuts wind force for the birds that follow. This decrease in wind force means that the birds use up to 70 percent less energy during their flight. When the lead bird becomes tired, a more rested bird takes over that position.
But saving energy is important for more than one reason. Sometimes food is short during migration flights. Keeping energy enables the birds to fly longer distances between meals.
When food is sighted, the birds guide one another in a different way. When a bird identifies a familiar feeding area, it might turn around in order to signal the group to change direction. Then, this bird becomes the new leader. It helps guarantee that other birds will know exactly where it is going. Then the whole group makes a change in direction, gently streaming from the sky down to the ground. This formation is like an arrow pointing to the location of food.
Scientists have also studied the birds that sometimes fly in a ball-like formation. Researchers believe that the birds come together if a predator（天敌） is spotted. The predator may then become impatient waiting for a single bird to fly away from the group. The birds will often dip and dive as a group, frustrating even the most persistent enemy. Scientists report that this is a very effective method of defense against an attack.
The birds care for their fellow fliers through teamwork. As transportation expert Henry Ford once said, “If everyone is moving forward together, then success takes care of itself.” When it comes to teamwork, these feathered fliers are a soaring success! According to the passage, we can learn that birds ___________.

Almost every machine with moving parts has wheels, yet no one knows exactly when the first wheel was invented or what it was used for. We do know, however, that they existed over 5, 500 years ago in ancient Asia.
The oldest known transport wheel was discovered in 2002 in Slovenia. It is over 5, 100 years old. Evidence suggests that wheels for transport didn’t become popular for a while, though. This could be because animals did a perfectly good job of carrying farming tools and humans around.
But it could also be because of a difficult situation. While wheels need to roll on smooth surfaces, roads with smooth surfaces weren’t going to be constructed until there was plenty of demand for them. Eventually, road surfaces did become smoother, but this difficult situation appeared again a few centuries later. There had been no important changes in wheel and vehicle design before the arrival of modern road design.
In the mid-1700s, a Frenchman came up with a new design of road—a base layer(层)of large stones covered with a thin layer of smaller stones. A Scotsman improved on this design in the 1820s and a strong, lasting road surface became a reality. At around the same time, metal hubs(the central part of a wheel)came into being, followed by the pneumatics tyre(充气轮胎)in 1846. Alloy wheels were invented in 1967, sixty years after the appearance of tarmacked roads(柏油路).As wheel design took off, vehicles got faster and faster.What might explain why transport wheels didn’t become popular for some time?
| A．Few knew how to use transport wheels. |
| B．Humans carried farming tools just as well. |
| C．Animals were a good means of transport. |

| B．It improved after big changes in vehicle design. |
| C．It was promoted by fast-moving vehicles. |
| D．It provided conditions for wheel design to develop. |

Doctors are known to be terrible pilots. They don’t listen because they already know it all. I was lucky: I became a pilot in 1970, almost ten years before I graduated from medical school. I didn’t realize then, but becoming a pilot makes me a better surgeon. I loved flying. As I flew bigger, faster planes, and in worse weather, I learned about crew resource management(机组资源管理),or CRM, a new idea to make flying safer. It means that crew members should listen and speak up for a good result, regardless of positions.
I first read about CRM in 1980.Not long after that, an attending doctor and I were flying in bad weather. The controller had us turn too late to get our landing ready. The attending doctor was flying; I was safety pilot. He was so busy because of the bad turn, he had forgotten to put the landing gear(起落架)down. He was a better pilot—and my boss—so it felt unusual to speak up. But I had to: Our lives were in danger. I put aside my uneasiness and said,“We need to put the landing gear down now!”That was my first real lesson in the power of CRM, and I’ve used it in the operating room ever since.
CRM requires that the pilot/surgeon encourage others to speak up. It further requires that when opinions are from the opposite, the doctor doesn’t overreact, which might prevent fellow doctors from voicing opinions again. So when I’m in the operating room, I ask for ideas and help from others. Sometimes they’re not willing to speak up. But I hope that if I continue to encourage them, someday someone will keep me from“landing gear up”. What does the author say about doctors in general?
| A．They like flying by themselves. |
| B．They are unwilling to take advice. |
| C．They pretend to be good pilots. |
| D．They are quick learners of CRM. |
The author deepened his understanding of the power of CRM when .
| A．he saved the plane by speaking up |
| B．he was in charge of a flying task |
| C．his boss landed the plane too late |
| D．his boss operated on a patient |
In the last paragraph“landing gear up”probably means .
| A．following flying requirements |
| B．overreacting to different opinions |
| C．listening to what fellow doctors say |
| D．making a mistake that may cost lives |
