When he first rose to stardom in the NBA, Yao Ming could not possibly have known the influence he would have on the American understanding of China.
In the eyes of many Americans, Chinese are short, bookish, and not especially athletic. Yao, 26, has turned that image on its head. A giant at 2.26 metres, he has been the most talked-about player in the league since he topped the NBA draft(选秀)in 2002.
When Yao first joined the Rockets and struggled with an American style of basketball, many were quick to label(标记)Yao “a failure”. But Yao played on. He did not let the criticism affect his performance. Even when former NBA star Charles Barkley bet that Yao could not score more than 19 points in a single game, Yao kept his self-respect. The same cannot be said for Barkley, who was forced to kiss a real donkey’s ass(屁股)when Yao passed the 19-point mark early in his first season.
For Americans, Yao’s polite and friendly personality is a welcome contrast to the rude behaviour of the NBA’s bad boys. Compared with most other NBA players, Yao Ming is a true gentleman. He respects all of his opponents(对手), even those who are not friendly to him.
“He is so wise and humourous that he seems like a diplomat(外交家)rather than a basketball player sometimes,” said Ron Burke, an NBA TV reporter.
In addition, Yao’s witty answers have changed the opinion that Chinese people are boring. When asked what were his favourite English words, Yao told the press that the five words were “This is the last question.” Yao is winning supporters within the league as well. After a Rockets-Lakers game that Shaquille O’Neal had to sit out with an injury, O’Neal said, “You played pretty good, Yao Ming.” Yao replied, “That’s because you weren’t there.”

After a week he began calling at the Fisher Bank. He showed his passport. “Nothing has come for you,” he was told. This went on for two weeks and Mr. Frank got very worried. He sent a telegram to his brother, but there was no reply. In the fourth week Mr. Frank was arrested for failing to pay his hotel bill. His passport was taken from him. He tried to explain the problem, but no one believed him. He was sent to prison for six days.
When he came out, he went immediately to the Fisher bank. The clerk he spoke to was a new man. “Have you received $500 for me?” he ask, “My name is Jackson Frank.” The clerk checked his books. “Yes, Jackson, it’s here. It came by telegram.—let me see—oh, more than two months ago. We wondered where you were.” He showed Mr. Frank the order. The order read:“Pay Mr. Frank Jackson the sum of $500...” “ But my name is Jackson Frank, not Frank Jackson.” “Oh, that’s all right, sir. It was in our books under the letter ‘J’, but it’s your money.” The clerk laughed, “A human mistake, sir! We’re all human beings, so we all make mistakes.

【推荐2】Joseph Frederick Engelberger, the father of robotics, was born on July 26, 1925, in Brooklyn. He received his B. S. in physics in 1946, and M. S. in Electric Engineering in 1949 from Columbia University. He worked as an engineer with Manning, Maxwell and Moore, and then he met George Devol at a party in 1956, two years after Devol had designed and patented an industrial robotic arm. However, Manning, Maxwell and Moore was sold and Engelberger’s division was closed that year.
Finding himself jobless but with a business partner and an idea, Engelberger co-founded Unimation with Devol, creating the world’s first robotics company. And the introduction of robotics to the manufacturing process effectively transformed the automotive industry. Over the next two decades, the Japanese took the lead by investing heavily in robots to replace people performing certain tasks. In Japan, Engelberger was widely described as a key player in the post-war ascendancy (支配地位,优势) of Japanese manufacturing quality and efficiency.
After observing the help his aging parents needed, Engelberger saw the robotics automation could be used in the medical field. In 1984, Engelberger founded Transitions Research Corporation (TRC). He introduced the HelpMate and hoped to kick-start a new industry for in-home robots, but he started in 1988 by selling his first HelpMate to Danbury Hospital. The medical robot was successful enough that the hospital ended up purchasing another, and within a decade, well over 100 hospitals worldwide operated HelpMates.
After Engelberger was awarded the Japan Prize in 1997, Senator Joseph Lieberman delivered a speech in the U. S. Senate in praise and recognition of the inventor, calling the HelpMate an example that shows the federal investment in science and technology for patients can lead to new products that employ Americans and make for a better quality of life.
Engelberger liked working. So even after he got into his 80s, he remained active in the promotion and development of robots for use in elder care. He died on December 1, 2015, in Newtown, a little more than four months after celebrating his 90th birthday.
1. Which statement about Engelberger may the author agree with?A.He was most popular among the Japanese. |
B.He finished his higher education in his twenties. |
C.He had great admiration for Devol as an inventor. |
D.He and Devol invented the first robotic arm together. |

A student, Evalthus, heard of this famous teacher and asked him to give him lessons. However, Evalthus didn’t want to pay for his lessons at once, and after some discussion it was finally agreed between them that Evalthus should pay only if he won his first case in the court. For if he won, it would prove that he had been taught well.
The lessons began and Evalthus proved himself to be a good student. But he refused to pay Protagoras anything at the end of his studies.
Protagoras therefore took Evalthus to the court and told the judges that he wanted his money. He explained that he must be paid whether he won or lost the case. “Whatever you decide,” he declared(宣称)to the judges, “ I must be paid. For if you decide in my fovor , then I win the case, and so I must be paid . But If you decide against me, then Evalthus has won his first case in the court; according to our agreement, he must pay his lessons. Therefore I shall get my money whatever happens.”
The Athenian judges found no fault in it, so they asked Evalthus to reply.
“No, it’s quite clear,” said Evalthus, “ that I need not pay. If the judged decide in my favor, then I have won the case, and I need not to pay. But if Protagoras wins, then I have lost my first case. Therefore, according to our agreement, I do not have to pay. So I need not pay in any event.”
As both arguments appeared to be faultless, the judges were unable to come to a decision. They therefore ordered the two men to appear before them again one hundred years later.
1. Evalthus would pay Protagoras _______________.
A.before he started his lessons |

【推荐2】Have you ever heard of invisible ink? You may have seen it in movies. When light is shone on the paper which invisible ink is written on, you can read it!
As magical as this seems, the change in color is due to science. The ink is absorbing higher energy light and giving lower energy light. This reaction is an example of fluorescence(荧光).
Light is a very broad term that describes a range of electromagnetic rays, including gamma rays, infrared light(红外光)and ultraviolet light. One part of the electromagnetic visible light is the colors that we can see with the human eye. These rays travel in curvy lines and each type of the ray is characterized by a different wave pattern. For example, Gamma rays have a shorter wavelength than infrared light. Shorter wavelength is connected with higher energy, so gamma rays also have more energy than infrared light.
Corals(珊瑚)are animals that live underwater. And the corals in the Red Sea exhibit fluorescence. Why is this happening? Scientists have shown that fluorescent objects absorb higher energy light and release lower energy light. Since the corals of the Red Sea are deep in the water where there is very little visible light, scientists theorize that these corals absorb ultraviolet light and produce visible light. They have special photo proteins, which enable them to change invisible light to visible light.
Fluorescence is not just used to create pretty colors. Corals have developed photo proteins for a biological reason. The visible light is used by algae(海藻), which are eaten by the coral, to make food through photosynthesis(光合作用). The visual character of these photo proteins could also be used for biomedical research. They can highlight cells and cell structures under a microscope.
Isn't it amazing that a simple organism that we don't think very much of is not only grand but could also have so many potential uses in medical research!

【推荐1】Stage lighting is too-often an underappreciated art for theatergoers. Not only does light illuminate (照亮) the action you’re watching, it also directly affects the emotion and subtext of a scene. Would Romeo and Juliet be as swoon-worthy without just the right wash of romantic colors?
In short, stage lighting isn’t just illumination. It is design, art, emotion, and subtext. It’s a beautiful entrance into the world of stagecraft and design.
We’re used to a world of smart computers, color gels, and all sorts of electronic awesomeness, but the early days of stage performance in human history? Not so lucky. They had to use candles, flashlights, flames, and simple lighting effects to illuminate and shade the action being played out on stage.
In the early days of Greek theatre, for instance, most plays were staged in daylight, to simplify production and to take the fullest advantage of the sunshine.
But by Shakespeare’s time, even though many productions were still taking advantage of natural light through afternoon stagings (上演), stage lighting nevertheless included everything from the candles behind the footlights to the use of torches, candles, and basic coverings to allow for more control of the lighting from scene to scene.
However, today’s stage lighting tools are a heady combination of technology and creativity and truly allow designers to let their imaginations take flight. Requiring their own vocabulary of sorts, the tools of today’s lighting designers are high-tech marvels that are a far cry from the original candles and torches of old, but all accomplish the same goal - beautiful illumination for the action onstage. In the performing arts, light itself is a part of the performance, and the work of the light board operator can often feel very much like a dance of sorts.

Society tends to think of high school dropouts as kids who just can’t cut it. They are lazy, and perhaps not too bright. So researchers were surprised when they asked more than 450 kids who quit school about why they left.
“The vast majority actually had passing grades and they were confident that they could have graduated from high school.” John Bridgeland, the executive researcher said. About one million teens leave school each year. Only about half of African-American and Hispanic(美籍西班牙的)students will receive a diploma(证书), and actually all dropouts come to regret their decision. So, if failing grades don’t explain why these kids quit, what does? Again, John Bridgeland: “The most dependable finding was that they were bored.” “They found classes uninteresting; they weren’t inspired or motivated. They didn’t see any direct connection between what they were learning in the classroom to their own lives, or to their career aspirations.”
The study found that most teens who do drop out wait until they turn sixteen, which happens to be the age at which most states allow students to quit. In the U.S., only one state, New Mexico, has a law requiring teenagers to stay in high school until they graduate. Only four states: California, Tennessee, Texas and Utah, plus the District of Columbia, require school attendance until age 18, no exceptions. Jeffrey Grin, another researcher, says raising the compulsory attendance age may be one way to keep more kids in school.
“As these dropouts look back, they realize they’ve made a mistake. And anything that sort of gives these people an extra push to stick it out and see it through to the end, is probably helpful measure.”
New Hampshire may be the next state to raise its school attendance age to 18. But critics say that forcing the students unwilling to continue their studies to stay in school misses the point—the need for reform. It’s been called for to reinvent high school education to make it more challenging and relevant, and to ensure that kids who do stick it out receive a diploma that actually means something.

A.they have failing grades |

Sir Isaac Newton was seated in his garden on a summer evening, when he saw an apple fall from a tree. He began to think, and, in trying to find out why the apple fell, discovered how the earth, sun, moon, and stars are kept in their places.
A boy named James Watt sat quietly by the fireside, watching the lid ( 盖子) of the tea kettle as it moved up and down. He began to think,and he wanted to find out why the steam in the kettle moved the heavy lid. From that time he went on thinking and thinking and when he became a man, he improved the steam engine so much that it could, with the greatest ease, do the work of many horses.
James Ferguson was a poor Scotch shepherd (羊倌) boy. Once, seeing the inside of a watch, he was filled with wonder.“Why should I not make a watch?”he thought. But how was he to get the materials out of which to make the wheels and the mainspring (钟表等的主发条)? He soon found how to get them: he made the mainspring out of a piece of whalebone. He then made a wooden clock which kept good time. He began, also, to copy pictures with a pen, and portraits (肖像) with oil colors. In a few years, while still a small boy, he earned money enough to support his father. When he became a man, he went to London to live. Some of the wisest men in England, and the king himself, used to attend his lectures. His motto was, “I will think of it.” and he made his thoughts useful to himself and the world.

【推荐1】Anyone who is afraid of failure and afraid to face challenges will never taste success, so said our professor in marketing. I laughed it off at that time, but got frightened when it actually happened in my life.
I landed in a small city in the Middle East to set up a firm, a world-class car rental firm. Having decided on the project, I earnestly settled in preparation. With a positive mind, I told myself nothing should stop me now, and was more than keen to make it a success.
However, the least expected thing happened. Iraq invaded Kuwait. Tension ran high in the region. Eventually the war broke out, and many people fled the country, leaving my firm in deep trouble.
As usual, “things become difficult, and every effort seems to bring disappointment, it can be tempting to lower your expectations or even water down your goals and ambitions.” I was no exception. I thought of running away. I remembered the words of Thomas Edison, “Many of life's failures are people who did not realize how close they were to succeed when they gave up.”
I decided to hang on, telling myself, “I am not afraid of challenges and obstacles.” I stayed on through months of uncertainty and insecurity. Finances ran low, and banks could not wait to get their dues. To add to all this, the banks even threatened to take all my vehicles. I felt I made a wrong decision to move there. I was now ready to face failure.
I was living against all hopes, believing that something good would happen. After 2 months the war ended. My persistence paid off: people started flooding back and the car bookings picked up, five times over.
Success comes to the one who dares, even after failure, to think positively and look forward confidently. After all, it is only the experience that makes a man tough. Failure does not mean you will never make it. It means that it will take a little longer. It provides us with a learning experience.

【推荐2】"What would you do if you were not in science?" I was once asked during an interview many years ago.1 hadn't really thought about it before. A constructor? I had shown interest in construction. A musician? It was appealing, but I knew I wasn't good enough. "A mailman," I shouted out. "So I could walk around all day and think about things." Little did I know then that, after a 30-year career in science, I would end up as a letter carrier.
I first became inspired by the idea that my work could make a practical impact in the world after I changed from academia to biotech. I had initially been attracted to scientific research by the fun of solving problems and discovering something new. As I started in biotech and my work became more applied, I realized that my research could lead to potential treatments for human disease.
However, none of my projects resulted in anything real to help people. My first biotech job ended when the company restructured. I got a job at another biotech company, but it went bankrupt one year later. Eventually, after some part-time consulting work, I decided I needed something more permanent, but I failed to find another full-time position in a science-related field. I started to wonder how I could still make a meaningful contribution.
I decided to get a job as a letter carrier in a post office. I have 30 years of experience conducting scientific research, yet here I feel a little sad when I am delivering mail. But I try to keep an open mind. Although I miss research, I do enjoy getting to walk around and think about things. Lately I've been thinking about the COVID-19 and my career. I certainly hope I'm making a difference in society by delivering medicines and checks. Now, I think I'll make a more positive impact on people's lives than before.

【推荐3】In an experiment to track the effects of insecticide (杀虫剂) on birds in the wild, scientists caught 24 sparrows as they migrated(迁徙) north from Mexico and the southern United States to Canada. The team fed half of those birds on a low amount of the commonly used agricultural insecticide and the other half with a slightly higher amount. An additional 12 birds were caught and fed on only sunflower oil. Within hours, the birds fed insecticide began to lose weight and ate less food. Birds given the higher amount lost 6 percent of their weight within six hours.
The findings suggest that insecticide, already effective in dropping bee populations, could also reduce bird populations. There is clear evidence that since 1966, the populations of nearly three-quarters of farmland birds have dropped.
The researchers fed the birds with carefully measured amounts of insecticide mixed with sunflower oil. In the wild, birds might feed on seeds coated with insecticide. Christy Morris-sey, a biologist at the University of Saskatchewan, Canada says, "Though the birds fed with the insecticide continued their migration, there's still much we don't know about how repeated exposures to the insecticide might affect a bird. "
After observing the birds in the lab, Morrissey and colleagues tracked the birds with lightweight trackers and kept records as they continued their spring migration. The highest fed birds stayed 3. 5 days longer near the site where they were caught-possibly to recover and regain strength than birds that weren't fed with the insecticide. Birds given the lower amount of insecticide stuck around for three days, and those which weren't fed with insecticide flew away after half a day. Tracking the tested birds showed that they all fell behind the others in their migration.
