A year ago, August, Dave Fuss lost his job driving a truck for a small company in west Michigan. His wife, Gerrie, was still working in the local school cafeteria, but it was hard for Dave to find work, and the price of everything was rising. The Fusses were at risk of joining the millions of Americans who have lost their homes in recent years. Then Dave and Gerrie received a timely gift—$7,000, a legacy(遗产) from their neighbors Ish and Arlene Hatch, who died in an accident. “It really made a difference when we were meeting difficulty .”says Dave.
But the Fusses weren’t the only folks in Alto and the neighboring town of Lowell to receive unexpected legacy from the Hatches. Dozens of other families were touched by what the Hatches had done. In some cases, it was a few thousand dollars; in others, it was more than $100,000.
It surprised nearly everyone that the Hatches had so much money, more than $3 million—they were an elderly couple who lived in an old house on what was left of the family farm.
Children of the Great Depression, Ish and Arlene were known for their habit of saving. They preferred comparison shopping and would go from store to store, checking prices before making a new purchase.
Through the years, the Hatches paid for local children to attend summer camps when their parents couldn’t afford it. “Ish and Arlene never asked if you needed anything,” says their friend Sandy Van Weelden, “They could see things they could do to make you happier, and they would do them.”
Even more extraordinary was that the Hatches gave away their farmland. It was the Hatches’ wish that their legacy—a legacy of kindness as much as one of dollars and cents—should enrich the whole community and last for generations to come.

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.”

For some people, music is no fun at all. About four percent of the population is what scientists call “amusic.” People who are amusic are born without the ability to recognize or reproduce musical notes (音调). Amusic people often cannot tell the difference between two songs. Amusics can only hear the difference between two notes if they are very far apart on the musical scale.
As a result, songs sound like noise to an amusic. Many amusics compare the sound of music to pieces of metal hitting each other. Life can be hard for amusics. Their inability to enjoy music set them apart from others. It can be difficult for other people to identify with their condition. In fact, most people cannot begin to grasp what it feels like to be amusic. Just going to a restaurant or a shopping mall can be uncomfortable or even painful. That is why many amusics intentionally stay away from places where there is music. However, this can result in withdrawal and social isolation. “I used to hate parties,” says Margaret, a seventy-year-old woman who only recently discovered that she was amusic. By studying people like Margaret, scientists are finally learning how to identify this unusual condition.
Scientists say that the brains of amusics are different from the brains of people who can appreciate music. The difference is complex, and it doesn’t involve defective hearing. Amusics can understand other nonmusical sounds well. They also have no problems understanding ordinary speech. Scientists compare amusics to people who just can’t see certain colors.
Many amusics are happy when their condition is finally diagnosed (诊断). For years, Margaret felt embarrassed about her problem with music. Now she knows that she is not alone. There is a name for her condition. That makes it easier for her to explain. “When people invite me to a concert, I just say, ‘No thanks, I’m amusic,’” says Margaret. “I just wish I had learned to say that when I was seventeen and not seventy.”(335 words)Which of the following is true of amusics?
| A．Listening to music is far from enjoyable for them. |
| B．They love places where they are likely to hear music. |
| C．They can easily tell two different songs apart. |
| D．Their situation is well understood by musicians. |

"Indeed"George Washington wrote in his diary in 1785, "some kind of fly,or bug,had begun to eat the leaves before I left home." But the father of America was not the father of bug.When Washington wrote that, Englishmen had been referring to insects as bugs for more than a century, and Americans had already created lightning-bug(萤火虫). But the Enlish were soon to stop using the bugs in their language, leaving it to be the Americans to call a bug a bug in the nineteenth and twentieth centuries.
The American bug could also be a person, referring to someone who was crazy about a particular activity.Although fan became the usual term, sports fans used to be called racing bugs, baseball bugs and the like.
Or the bug could be a small machine or object, for example, a bug-shaped car. The bug could also be a burlar alarm, from which comes the expression to bug, that is, "to install(安装) an alarm". Now it means a small piece of equipment that people use for listening secretly to others' conversations.Since the 1840s,to bug has long meant "to cheat",and since the 1994s it has been annoying.
We also know the bug as a flaw n a computer program or other design.That meaning dates back to the time of Tomas Edison.In 1878 he explained bugs as "little problems and difficulties" that required months of stdy and labor to overcome in developing a successful product. In 1889 it was recorded that Edison "had been up the two previous nights discovering′a bug′ in his invented record player."

Here is an astonishing and signficant fact:Mental work alone can’t make us tired. It sounds absurd. But a few years ago, scientists tried to find out how long the human could labor without reaching a stage of fatigue(疲劳). To the amazement of these scientists, they discovered thett blood passing through the brain, when it is active, shows no fatigue at all! If we took a drop of blood from a day labourer, we could find it full of fatigue toxins(毒素) and fatigue products. But if we took blood from the brain of Albert Einstein, it would show no fatigue toxing at the end of the day.
So far as the brain is concerned, it can work as well and swiftly at the end of eight or even twelve hours f efforts as at the beginning. The brain is totally tireless. So what makes us tired.
Some scientists declare that most of our fatigue come from our mental and emotional(情感的) attitudes. One of England’s most outstanding scientists. J. A. Hadfield,says,“The greater part of the fatigue from which we suffer is of mental origin. In fact,fatigue of purely physical origin is rare.” Dr. Brill, a famous American scientist, goes even further. He declares,“One hundred percent of the fatigue of a sitting worker in good health is due to emotional problems.”
What kinds of emotions make sitting workers tired?Joy?Satifaction?No!A feeling of being bored,anger,anxiety,tenseness,worry,a feeling of nt being appreciated---those are emotions that tire sitting workers.Hard work by itself seldom causes fatigue.We get tired because our emotions produce nervousness in the body.What surprised the scientists a few years ago?
| A．Fatigue toxinscould hardly be found in a labour’s blood. |
| B．Albert Eistein didn’t feel worn out after a day’s work. |
| C．The brain could wrk for many hours without fatigue. |
| D．A mental worker’s blood was filled with fatigue toxins. |
According to the authour,which of the following can make sitting worker tired？
| A．Challenge mental work. |
| B．Unpleasant emotions. |
| C．Endless tasks. |
| D．Physical labor. |
What’s the authour’s attitude towards the scientists’ ideas?
| A．He agrees with them. |
| B．He doubts them |
| C．He argues against them. |
| D．He hesitates to accept them. |
We can infer from the passage that in order to stay energic, sitting workers need to ______.
| A．have some good blood |
| B．enjoy their work |
| C．exercise regularly |
| D．discover fatigue toxin |
