You can usually tell when your friends are happy or angry by the looks on their faces or by their actions. This is useful because reading their emotional expressions helps you to know how to respond to them. Emotions have evolved to help us respond to important situations and to convey our intentions to others. But does raising the eyebrows and rounding the mouth say the same thing in Minneapolis as it does in Madagascar? Much research on emotional expressions has centered on such questions.
According to Paul Ekman, the leading researcher in this area, people speak and understand substantially the same "facial language". Studies by Ekman's group have demonstrated that humans share a set of universal emotional expressions that testify to the common biological heritage of the human species. Smiles, for example, signal happiness and frowns indicate sadness on the faces of people in such far- flung places as Argentina, Japan, Spain, Hungary, Poland , Sumatra ,the United States, Vietnam, the jungles of New Guinea , and the Eskimo villages north of Artic Circle. Ekman and his colleagues claim that people everywhere can recognize at least seven basic emotions: sadness, fear, anger, disgust, contempt, happiness, and surprise. There are, however, huge differences across cultures in both the context and intensity of emotional displays - the so called display rules. In many Asian cultures, for example, children are taught to control emotional responses - especially negative ones- while many American children are encouraged to express their feelings more openly. Regardless of culture, however, emotions usually show themselves, to some degree, in people's behavior. From their first days of life, babies produce facial expressions that communicate their feelings.
The ability to read facial expressions develops early, too. Very young children pay close attention to facial expressions, and by age five, they nearly equal adults in their skill at reading emotions on people's faces. This evidence all points to a biological underpinning for our abilities to express and interpret a basic set of human emotions. Moreover, as Charles Darwin pointed out over a century ago, some emotional expressions seem to appear across species boundaries. Cross - cultural psychologists tell us that certain emotional responses carry different meanings in different cultures. For example, what emotion do you suppose might be conveyed by sticking out your tongue? For Americans, this might indicate disgust, while in China it can signify surprise. Likewise, a grin on an American face may indicate joy, while on a Japanese face it may just as easily mean embarrassment. Clearly, culture influences emotional expressions.

Many people believe that watching television has resulted in lower reading standards in schools. However, the link between television and printed books is not as simple as that. In many cases, television actually encourages people to read for example, when a book is turned into a TV series, its sales often go up. One study of this link examined six-year-old children who were viewing a special series of 15-minute programmes at school. The series was designed to encourage the love of books, as well as to develop the basic mechanical skills of reading. Each programme is an animated film of a children's book. The story is read aloud while certain key phrases from the book appear on the screen, beneath the picture. Whenever a word is read, it is also highlighted on the TV screen.

One finding was that watching these programmes was very important to the children. If anything prevented them from seeing a programme, they were very disappointed. What's more, they wanted to read the books which the different parts of the series were based on.

The programmes also gave the children more confidence when looking these books. As a result of their familiarity with the stories, they would sit in pairs and read the stories aloud to each other. On each occasion, the children showed great sympathy when discussing a character in a book because they themselves had been moved when watching the character on TV.

What kind of film is each program?

   Contrary to popular belief, one does not have to be a trained programmer to work online. Of course, there are plenty of jobs available for people with high-tech computer skills, but the growth of new media has opened up a wide range of Internet career opportunities requiring only a minimal level of technical expertise. Probably one of the most well-known online job opportunities is the job of webmaster. However, it is hard to define one basic job description for this position. The qualifications and responsibilities depend on what tasks a particular organization needs a webmaster to perform.

   To specify the job description of a webmaster, one needs to identify the hardware and software that the website the webmaster will manage is running on. Different types of hardware and software require different skill sets to manage them. Another key factor is whether the website will be running internally (at the firm itself) or externally (renting shared space on the company servers). Finally, the responsibilities of a webmaster also depend on whether he or she will be working independently, or whether the firm will provide people to help. All of these factors need to be considered before one can create an accurate webmaster job description.

   Webmaster is one type of Internet career requiring in-depth knowledge of the latest computer applications. However, there are also online jobs available for which traditional skills remain in high demand. Content jobs require excellent writing skills and a good sense of the web as a “new media”.

   The term “new media” is difficult to define because it encompasses a constantly growing set of new technologies and skills. Specifically, it includes websites, email, Internet technology, CD-ROM, DVD, streaming audio and video, interactive multimedia presentations, e-books, digital music, computer illustration, video games, virtually reality, and computer artistry.

   Additionally, many of today’s Internet careers are becoming paid-by-the-job professions. With many companies having to downsize in tough economic items, the outsourcing and contracting of freelance workers online has become common business practice. The Internet provides an infinite pool of buyers from around the world with whom freelancers are able to work on projects with companies outside their own country of residence.

   How much can a person make in these kinds of career? As with many questions related to today’s evolving technology, there is no simple answer. There are many companies willing to pay people with technical Internet skills salaries well above $70,000 a year. Generally, webmasters start at about $30,000 per year, but salaries can vary greatly. Freelance writers working online have been known to make between $40,000 and $70,000 per year.

My city has been changing since the municipal authority had a plan to renovate the canal systems. The project cost a huge amount of money which was from the support of the world bank and the city’s budget. Before the renovation, the canal was the dirtiest place full of rubbish along its sides. Many ramshackle shacks were built to be shelters of the impoverished working families migrating to this city to earn their living. Household wastes were directly dumped into the canal, resulting in the very contaminated environment. It was said that the very unpleasant smell releasing from the canal was unable to be eliminated, and the living condition there would not be better. However, thanks to the advanced technology and methods as well as the city authority’s effort, everything has been changing. There is no longer the disgusting smell or shabby houses along both sides of the canal. Instead, the road running parallel to the canal is now full of shade of greenery and the water now is so clean that it is a friendly habitat for a variety of fish. The residents now can walk or do morning exercise on the sidewalks along the banks to enjoy the fresh atmosphere. Former inhabitants are also relocated in new apartments with much better living conditions than before. The canal creates not only a beautiful urban landscape, but also brings a lot of economic benefits to local dwellers. Because of its reformation, the city is changing fast too.

With Robert Laurent and William Zorach, direct carving enters into the story of modern sculpture in the United States. Direct carving - in which the sculptors themselves carve stone or wood with mallet and chisel - must be recognized as something more than just a technique. Implicit in it is an aesthetic principle as well: that the medium has certain qualities of beauty and expressiveness with which sculptors must bring their own aesthetic sensibilities into harmony. For example, sometimes the shape or veining in a piece of stone or wood suggests, perhaps even dictates, not only the ultimate form, but even the subject matter.
The technique of direct carving was a break with the nineteenth-century tradition in which the making of a clay model was considered the creative act and the work was then turned over to studio assistants to be cast in plaster or bronze or carved in marble. Neoclassical sculptors seldom held a mallet or chisel in their own hands, readily conceding that the assistants they employed were far better than they were at carving.
With the turn-of-the-century Crafts movement and the discovery of nontraditional sources of inspiration, such as wooden African figures and masks, there arose a new urge for hands-on, personal execution of art and an interaction with the medium. Even as early as the 1880's and 1890's, nonconformist European artists were attempting direct carving. By the second decade of the twentieth century, Americans - Laurent and Zorach most notably - had adopted it as their primary means of working.
Born in France, Robert Laurent (1890-1970) was a prodigy who received his education in the United States. In 1905 he was sent to Paris as an apprentice to an art dealer, and in the years that followed he witnessed the birth of Cubism, discovered primitive art, and learned the techniques of woodcarving from a frame maker.
Back in New York City by 1910, Laurent began carving pieces such as The Priestess, which reveals his fascination with African, pre-Columbian, and South Pacific art. Taking a walnut plank, the sculptor carved the expressive, stylized design.
It is one of the earliest examples of direct carving in American sculpture. The plank's form dictated the rigidly frontal view and the low relief. Even its irregular shape must have appealed to Laurent as a break with a long-standing tradition that required a sculptor to work within a perfect rectangle or square.

Bees, classified into over 10,000 species, are insects found in almost every part of the world except the northernmost and southernmost regions. One commonly known species is the honeybee, the only bee that produces honey and wax. Humans use wax in making candles, lipsticks, and other products, and they use honey as food. While gathering the nectar and pollen with which they make honey, bees are simultaneously helping to fertilize the flowers on which they land. Many fruits and vegetables would not survive if bees did not carry the pollen from blossom to blossom.

Bees live in a structured environment and social structure within a hive, which is a nest with storage space for the honey. The different types of bees each perform a unique function. The worker bee carries nectar to the hive in a special stomach called a honey stomach. Other workers make beeswax and shape it into a honeycomb, which is a waterproof mass of six-sided compartments, or cells. The queen lays eggs in completed cells. As the workers build more cells, the queen lays more eggs.

All workers, like the queen, are female, but the workers are smaller than the queen. The male honeybees are called drones; they do no work and cannot sting. They are developed from unfertilized eggs, and their only job is to impregnate a queen. The queen must be fertilized in order to lay worker eggs. During the season when less honey is available and the drones are of no further use, the workers block the drones from eating the honey so that they will starve to death.

The word “species” in the first sentence probably means ______.

"Until recently, the ‘Science of the future’ was supposed to be electronics and artificial intelligence. Today it seems more and more likely that the next breakthrough in technology will be brought about through a combination of those
two Sciences with organic chemistry and genetic engineering. This Science is the combination of biotechnology.
 Organic chemistry enables us to produce marvelous synthetic materials. However, it is still difficult to manufacture anything that has the capacity of wool to conserve heat and also to absorb moisture. Nothing that we have been able to produce so far comes anywhere near the combination of strength, lightness, and flexibility that we find in the bodies of ordinary insects.
 Nevertheless, scientists in the laboratory have already succeeded in ‘growing’ a material that has many of the characteristics of human skin. The next step may well be ‘biotech heart and eyes’ which can replace diseased organs in human beings. This will not be rejected by the body, as in the case with organs from humans.
 The application of biotechnology to energy production seems even more promising. In 1996, the famous science-fiction writer Arthur c. Clarke, many of whose previous predictions have come true, said that we may soon be able to develop remarkably cheap and renewable sources of energy. Some of these power sources will be biological. Clarke and others have warned us repeatedly that sooner or later we will have to give up our dependence on non-renewable power sources. Coal, oil and gas are indeed convenient. However, using them also means creating dangerously high levels of pollution. It will be impossible to meet the growing demand for energy without increasing that pollution to catastrophic levels unless we develop power sources that are both cheaper and cleaner."

   Dodder is an unusual and unwanted plant that attacks other plants. Except for its flowers, the plant looks like spaghetti noodles. Its almost leafless, thread–like stems hang down atop other plants that dodder needs to stay alive. Dodder does not produce its own food. Instead, it steals it from other plants. It feeds by sucking juices from the plant it is wrapped around, often making its host very weak or even killing it. Dodder can find other plants by their smell. When a dodder seedling starts growing, it follows the scent of plants it prefers, like tomato plants, potato plants, or other farm crops.

   Unlike most plants that usually grow in the direction of light or warmth, a dodder plant will grow in the direction of, for example, tomato odor––if a tomato happens to be growing nearby.

   However, a young dodder plant must find a host plant quickly. If it cannot catch a whiff of a potential host within a few days, it will dry up and disappear—even if there is plenty of water around. Once it finds a host, the young dodder plant will attach itself to it and start growing faster. At that point, the dodder plant will drop its root.

   Dodder is thus a difficult weed to manage and a real headache for farmers. When it does get out of hand, dodder can greatly reduce a farmer’s harvest or even destroy crops completely. Before sowing their produce, farmers in warm parts of the world often check to make sure no unwanted dodder seeds have intermingled with their crop seeds. This is a good way to stop dodder plants from sneaking their way into a crop field.

The expression get out of hand is closest in meaning to_________.

In the future, maybe all cars that run on petrol will be replaced by solar cars, which have been around for a while, but with recent developments in solar car design and the measurement of photovoltaic cells becoming smaller, the dream of a truly efficient solar car is more reality than fantasy. A solar car is a vehicle powered by photovoltaic cells, also called solar cells, which convert sunlight (light energy) into electrical energy. As a source of energy on earth, there is nothing like the sun: in a mere one thousandth of one second (.001) , the sun emits enough energy to fulfill our planet's energy needs for the next 5,000 years. It is a staggering fact, and an exciting one. Since the energy from the sun is responsible for renewable resources such as wind, tides, and heat, solar energy seems to offer the brightest future for not only cars, but for the entire energy crisis. Despite the appearance that solar energy may be the least, feasible among the current crop of alternative fuel propositions, new solar powered devices and more specifically solar powered cars are beginning to be developed. How do Solar Cars work?

The photovoltaic cells absorb photons from sunlight. This action generates heat, which the cells then convert into electrical energy and stores in an onboard battery. This process of conversion is called the photovoltaic effect. Not surprisingly, such a vehicle has zero emissions, and is very environmentally friendly. Unfortunately, at the moment photovoltaic cells are extremely inefficient, yet as time progresses the efficiency of these cells will grow. This will make solar energy and solar cars the fuel and car of the future - a closer reality.

Which can not help us to solve the problem of energy crisis?
