Etymology, the study of words and word roots, may sound like the kind of thing done by boring librarians in small, dusty rooms． Yet etymologists actually have a uniquely interesting job． They are in many ways just like archaeologists （考古学家） digging up the physical history of people and events． The special aspect of etymology is that it digs up history, so to speak, through the words and phrases that are left behind．
The English language, in particular, is a great field to explore history through words As a language, English has an extraordinary number of words． This is partly due to its ability to adapt foreign words so readily． For example, " English" words such as kindergarten （from German）, croissant （from French）, and cheetah （from Hindi） have become part of the language with little or no change from their original sounds and spellings． So English-language etymologists have a vast world of words to explore．
Another enjoyable thing about etymology for most word experts is solving word mysteries（谜）． No, etymologists do not go around solving murders, like the great detective Sherlock Holmes． What these word experts solve are mysterious origins of some of our most common words
One of the biggest questions English language experts have pursued is how English came to have the phrase OK． Though it is one of the most commonly used expressions, its exact beginning is a puzzle even to this day． Even its spelling is not entirely consistent-unless you spell it Okay, it is hard even to call it a word．
Etymologists have been able to narrow OK’s origin down to a likely, although not certain, source（来源）． It became widely used around the time of Martin Van Buren's run for president in 1840． His nickname was Old Kinderhook． What troubles word experts about this explanation is that the phrase appeared in some newspapers before Van Buren became well known． It is likely that Van Buren could be called its primary source Etymologists will doubtlessly keep searching for the initial source． However, it is clear that OK’s popularity and reputation have topped those of the American president to whom it has been most clearly linked．

President Coolidge’s statement, “The business of America is business,” still points to an important truth today—that business institutions have more prestige（威望）in American society than any other kind of organization, including the government. Why do business institutions possess this great prestige?
One reason is that Americans view business as being more firmly based on the ideal of competition than other institutions in society. Since competition is seen as the major source of progress and prosperity by most Americans, competitive business institutions are respected. Competition is not only good in itself, it is the means by which other basic American values such as individual freedom, equality of opportunity, and hard work are protected.
Competition protects the freedom of the individual by ensuring that there is no monopoly（垄断）of power. In contrast to one all-powerful government, many businesses compete against each other for profits. Theoretically, if one business tries to take unfair advantage of its customers, it will lose to competing business which treats its customers more fairly. Where many businesses compete for the customers’ dollars, they cannot afford to treat them like inferiors or slaves.
A contrast is often made between business, which is competitive, and government, which is a monopoly. Because business is competitive, many Americans believe that it is more supportive of freedom than government, even though government leaders are elected by the people and business leaders are not. Many Americans believe, then, that competition is as important, or even more important, than democracy（民主）in preserving freedom.
Competition in business is also believed to strengthen the ideal of equality of opportunity. Competition is seen as an open and fair race where success goes to the swiftest person regardless of his or her social class background. Competitive success is commonly seen as the American alternative to social rank based on family background. Business is therefore viewed as an expression of the idea of equality of opportunity rather than the aristocratic（贵族的）idea of inherited privilege.The statement “The business of America is business” probably means ________.

Monitoring global warming usually requires a Ph. D. and enough maths to glaze your eyes. But that Francisco Lopez and Ruby Nostrant track（记录）what climate change is doing to five different plants in Tucson, Arizona and they are only in the second grade.
“We are collecting data because the weather is changing and the plants are blooming,” Ruby explained.
Scores of other students at Borton Primary Magnet School and Sunnyside High School in Tucson are heading outdoors to be part of a new scientific push to figure out how the biological timing of the earth is changing. It’s a research project that the average person, even a kindergartner, can join in.
The National Phenology（生物气候学）Network is calling on volunteers to help track early spring blooms and eventually changes in animals caused by global warming. It’s called Project Budburst. When it was first open to the public last year, thousands of people participated in 26 states.
“All people can contribute to it by tracking the timing of flowering events or leaf-out events for plants and animals in their backyard,” said Phenology Network director Jake Weltzin. He calls the volunteers “citizen-scientists.”
The idea is that tracking flowers blooming—especially lilacs（丁香）; which everyday people have helped track for decades—is fairly simple. The Website http://www.Windows.ucar.edu/ citizen_science/budburst/index.html gives directions on what to look for in different parts of the country.
University of Maryland professor David Inouye said it’s so easy to figure out what’s blooming that a lack of special knowledge isn’t a problem.
University of Arizona ecology graduate student Lisa Benton coordinated（协调）the Tucson high school students as they looked at plants five minutes from their high school. Each student has specific guidelines and she’s been happy so far with the data she is getting. For his part, second-grader Francisco said he had fun helping out.
“I like going out in the desert,” he said. “I want to be an Einstein.”Francisco Lopez and Ruby Nostrant are monitoring global warming by __________.
| A．watching early spring blooms and changes in animals |
| B．studying the biological timing of earth |
| C．collecting data of the local weather |
| D．tracking the early spring blooms of some local plants |
Those who participate in Project Budburst are mostly ___________.
| A．ecology college graduates | B．high school students |
| C．common people | D．experts |
What David Inouye says suggests that ____________.
| A．the study carried out by students is convincing |
| B．the students still need special training to study climate change |
| C．it is difficult to study climate change |
| D．to figure out what’s blooming needs special knowledge |
Who is primary school student joining in the Project Budburst?
| A．Lisa Benton. | B．David Inouye |
| C．Francisco Lopez. | D．Jake Weltzin. |
We can conclude from the passage that _______.
| A．changes in animals caused by global warming happen earlier than those in plants |
| B．the biological timing of earth is changing because of climate change |
| C．the effect of climate change in Tucson, Arizona can be hardly noticed |
| D．all the plants in Tucson, Arizona are blooming earlier because of climate change |
Even before my father left us, my mother had to go back to work to support our family. Once I came out of the kitchen, complaining, “Mom, I can’t peel potatoes. I have only one hand.”
Mom never looked up from sewing. “You get yourself into that kitchen and peel those potatoes,” she told me. “And don’t ever use that as an excuse for anything again!”
In the second grade, our teacher lined up my class on the playground and had each of us race across the monkey bars, swinging from one high steel rod to the next. When it was my turn, I shook my head. Some kids behind me laughed, and I went home crying.
That night I told Mom about it. She hugged me, and I saw her “we’ll see about that” look. The next afternoon, she took me back to school. At the deserted playground, Mom looked carefully at the bars.
“Now, pull up with your right arm,” she advised. She stood by as I struggled to lift myself with my right hand until I could hook the bar with my other elbow. Day after day we practiced, and she praised me for every, rung I reached. I’ll never forget the next time, crossing the rungs, I looked down at the kids who were standing with their mouths open.
One night, after a dance at my new junior high, I lay in bed sobbing. I could hear Mom come into my room. “Mom,” I said, weeping, “none of the boys would dance with me.”
For a long time, I didn’t hear anything. Then she said, “Oh, honey, someday you’ll be beating those boys off with a bat.” Her voice was faint and cracking. I peeked out from my covers to see tears running down her cheeks. Then I knew how much she suffered on my behalf. She had never let me see her tears.Which of the following expressions can be used most suitably to describe Mom’s attitude when she made the child peel potatoes?

Human beings are the most intelligent of all animals because we are gifted with the ability to think and reason logically. Scientists and even common people with special intelligence have made a lot of inventions and contributions to modern lifestyle in the past. “Houses” have been the most popular area for discoveries and inventions in the past and even now.
Many household items have been the result of inventions of people who desired better functioning of the existent products. Every individual has intelligence and if it is used properly for the right purpose it leads to invention of a new tool or device. Many new household inventions are made almost every day and there are specific companies, which particularly keep a record of all these inventions.
A lot of inventions have been made recently in the household field. These products are patented(专利的)and have trade mark licenses(许可). The patented sliding cinch is a very simple but effective method to prevent shoulder stress and injury for those who work before computers all day long. Vanity PC is a type of computer furniture that specifically hides all the computer wires and keeps a clean and good look. All the outdoor dust, mud and snow can be kept out of the house by installing(安装)the dirt drain(排水管)at the entrance of the door. Another important invention is the automatic toilet night-light, in which a small light starts when the lid of the toilet seat is opened and closes as soon as the lid is closed.
These are some of the new household inventions invented mostly by common people. Thus, a variety of new household items are invented every day, which helps in a better functioning of household chores and in a more useful manner.The first paragraph tells us the importance of _________.
| A．the particular changes in houses |
| B．human beings’ role in making inventions |
| C．the advantages of modern lifestyle |
| D．the difference between human beings and animals |
What plays the most important role in causing people to invent new things?
| A．To earn more money and gain awards. |
| B．To be recorded by some special companies. |
| C．To improve the present living conditions. |

As we have seen, the focus of medical care in our society has been shifting from curing disease to preventing disease—especially in terms of changing our many unhealthy behaviors, such as poor eating habits, smoking, and failure to exercise. The line of thought involved in this shift can be pursued further. Imagine a person who is about the right weight, but does not eat very nutritious (有营养的) foods, who feels OK but exercises only occasionally, who goes to work every day, but is not an outstanding worker, who drinks a few beers at home most nights but does not drive while drunk, and who has no chest pains or abnormal blood counts, but sleeps a lot and often feels tired. This person is not ill. He may not even be at risk for any particular disease. But we can imagine that this person could be a lot healthier.
The field of medicine has not traditionally distinguished between someone who is merely “not ill” and someone who is in excellent health and pays attention to the body’s special needs. Both types have simply been called “well”. In recent years, however, some health specialists have begun to apply the terms “well” and “wellness” only to those who are actively striving to maintain and improve their health. People who are well are concerned with nutrition and exercise, and they make a point of monitoring their body’s condition. Most important, perhaps, people who are well take active responsibility for all matters related to their health. Even people who have a physical disease or handicap (缺陷) may be “well” in this new sense, if they make an effort to maintain the best possible health they can in the face of their physical limitations. “Wellness” may perhaps best be viewed not as a state that people can achieve, but as an ideal that people can strive for. People who are well are likely to be better able to resist disease and to fight disease when it strikes. And by focusing attention on healthy ways of living, the concept of wellness can have a beneficial impact on the ways in which people face the challenges of daily life.Today medical care is placing more stress on ________.
| A．keeping people in a healthy physical condition |
| B．monitoring patients’ body functions |
| C．removing people’s bad living habits |
| D．ensuring people’s psychological well-being |
In the first paragraph, people are reminded that ________.
| A．good health is more than not being ill |
| B．drinking, even if not to excess, could be harmful |

Traditionally, a person is considered “well” if he ________.
| A．does not have any unhealthy living habits |
| B．does not have any physical handicaps |
| C．is able to handle his daily routines |
| D．is free from any kind of disease |
According to the author, the true meaning of “wellness” is for people ________.
| A．to best satisfy their body’s special needs |
| B．to strive to maintain the best possible health |
| C．to meet the strictest standards of bodily health |
| D．to keep a proper balance between work and leisure |
