单选题{{B}}TEXT A{{/B}} For the executive producer of a network nightly news program, the workday often begins at midnight—as mine did during seven years with ABC's evening newscast①. The first order of business was a call to the assignment desk for a pre-bedtime rundown of latest developments. The assignment desk operates 24 hours a day, staffed by editors who move crews, correspondents and equipment to the scene of events. Assignment-desk editors are logistics experts; they have to know plane schedules, satellite availability, and whom to get in touch with at local stations and oversea broadcasting systems. They are required to assess stories as they break on the wire services sometimes even before they do—and to decide how much effort to make to cover those stories. When the United States was going to appeal to arms against Iraq, the number of correspondents and crews was constantly evaluated. Based on reports from the field and also upon the skilled judgments of desk editors in New York City, the fight number of personnel was kept on the alert. The rest were allowed to continue working throughout the world, in America and Iraq ready to move but not tied down by false alarms. The studio staff of ABC's "World News Tonight" assembles at 9 a. m. to prepare for the 6:30 "air" p.m. deadline. Overnight dispatches from outlying bureaus and press services are read. There are phone conversations with the broadcast's staff producers in domestic bureaus and with the London bureau senior producer, who coordinates overseas coverage. A pattern emerges for the day's news, a pattern outlined in the executive producer's first lineup. The lineup tells the staff what stories are scheduled; what the priorities are for processing film of editing tape; what scripts need to be written; what commercials are scheduled; how long stories should run and in what order. Without a lineup, there would be chaos. Each story's relative value in dollars and cents must be continually assessed by the executive producer. Cutting back satellite booking to save money might meant that an explanation delivered by an anchor person will replace actual photos of an event. A decline in live coverage could send viewers away and drive ratings down, but there is not enough money to do everything. So decisions must be made and made rapidly—because delay can mean a missed connection for shipping tape or access to a satellite blocked by a competitor. The broadcasts themselves require pacing and style. The audience has to be allowed to breathe between periods of intense excitement. A vivid pictorial report followed by less exacting materials allows the viewer to reflect on information that has just flashed by. Frequent switches from one anchor to another or from one film or tape report to another create a sense of forward movement. Ideally, leading and tags to stories are worked out with field correspondents, enabling them to fit their reports into the program's narrative flow so the audience's attention does not wander and more substance is absorbed②. Scripts are constantly rewritten to blend well with incoming pictures. Good copy is crisp, informative. Our rule: the fewer words the better. If a picture can do the work, let it.

单选题{{B}}TEXT B{{/B}} Most people today think of chocolate as something sweet to eat or drink that can be easily found in stores around the world. It might surprise you that chocolate was once highly treasured. Researchers at the University of Pennsylvania recently released a study. It suggested that people in Central and South America first gathered the cacao plant much earlier and for a different use than experts once thought. ① The researchers examined the chemistry of substances found in ancient clay containers that were over three thousand years old. They discovered that the substance came from an alcoholic drink made from the fruit of the cacao plant. The researchers believe it was the interest in cacao as an alcoholic drink that led to the use of its bitter seeds to make what is now known as chocolate. ② Historians believe the Maya people of Central America first learned to farm cacao plants around two thousand years ago. The Maya took the cacao trees from the rainforests and grew them in their gardens. They cooked the cacao seeds, and then crushed them into a soft paste. They mixed the paste with water and flavorful spices to make an unsweetened chocolate drink. The Maya poured the chocolate drink back and forth between two containers so that the liquid had a layer of bubbles, or foam. ③ Cacao and chocolate were an important part of Maya culture. There are often images of cacao plants on Maya buildings and art objects. Ruling families drank chocolate at special ceremonies. And, even poorer members of society could enjoy the drink once in a while. Historians believe that cacao seeds were also used in wedding ceremonies as a sign of the union between a husband and wife. The Aztec culture in current day Mexico also prized chocolate. But, the cacao plant could not grow in the area where the Aztecs lived. So, they traded to get cacao. They even used cacao seeds as a form of money to pay taxes or give as holy offerings to the gods. Only the very wealthy people in Aztec societies could afford to drink chocolate because cacao was so valuable. Some experts believe the word for chocolate came from the Aztec word "xocolatl" which in the Nahuatl language means “bitter water”. Others believe the word "chocolate" was created by combining Mayan and Nahuatl words. The explorer Christopher Columbus brought cacao seeds to Spain after his trip to Central America in 1502. But it was the Spanish explorer Hernando Cortes who understood that chocolate could be a valuable investment. In 1519, Cortes arrived in current day Mexico. He believed the chocolate drink would become popular with Spaniards. After the Spanish soldiers defeated the Aztec empire, they were able to seize the supplies of cacao and send them home. Spain later began planting cacao in its colonies in the Americas in order to supply the large demand for chocolate. The wealthy people of Spain first enjoyed a sweetened version of the chocolate drink. Later, the popularity of the drink spread throughout Europe. The English, Dutch and French began to plant cacao trees in their own colonies. Chocolate remained a drink that only wealthy people could afford to drink until the eighteenth century. During the period known as the Industrial Revolution, new technologies helped make chocolate less costly to produce.

单选题A breakthrough in the provision of energy from the sun for the European Economic Community could be brought forward by up to two decades, if a modest increase could be provided in the EEC's research effort in this field, according to the senior EEC scientists engaged in experiments in solar energy at EEC's scientific laboratories at Ispra, near Milan. The senior West German scientist in charge of the community's solar energy program, Mr. Joachim Gretz, told jurnalists that at present levels of research spending it was most unlikely that solar energy would provide as much as three percent of the Community's energy requirements even after the year 2000. But he said that with a modest increase in the present sums, devoted by the EEC to this work it was possible that the breakthrough could be achieved by the end of the next decade. Mr. Gretz calculates that if solar energy only provided three percent of the EEC's needs, this could still produce a saving of about a billion bounds in the present bill for imported energy each year. And he believes that with the possibility of utilizing more advanced technology in this field it might be possible to satisfy a much bigger share of the Community's future energy needs. At present the EEC spends about $2.6 millions a year on solar research at Ispra, one of the EEC's official joint research centers, and another $3 millions a year in indirect research with universities and other independent bodies.

单选题The cold is bad enough, but winter's shorter days make the season a downer, to say the least. But how real is seasonal affective disorder (known as SAD)? SAD is often a catch-all term to describe the winter dumps, but experts say it's often misused and the condition is actually less common than people think. "There are a lot of myths. SAD is not a myth. It is a mental disorder that is incompletely understood and also something that is complicated by questions about the role of evolutionary biology," says Dr. Jeffrey Lieberman, the president of the American Psychiatric Association. That diagnosis is different from the lows that many feel during the winter months. In fact, research shows many people overestimate the impact of seasons on their moods in general. Where is the line between SAD and the simple doldrums? How much winter sadness is the product of a mood-based disorder, and how much is a natural outcome of being cooped up indoors? SAD is considered a subtype of a mood disorder like depression or bipolar disorder (躁郁症), so a very small percentage are actually diagnosed with it. In order to meet the qualifications for a SAD diagnosis, according to the Mayo Clinic, an individual must be show the following: depression and other symptoms for a minimum of two consecutive years during the same season; depression-free periods following episodes of depression; unexplained behavior and mood changes. For most other cases of seasonal mood changes, Lieberman says making some lifestyle changes such as exercising or keeping good sleeping habits can help. "It's important to realize that just like people on Mondays have physical and emotional symptoms, you deal with it. You don't take a treatment for Mondays." It only warrants treatment when it starts to interfere with daily life, he says. What about the bright light lamps that claim to relieve depression during the darker months? They're based on the idea that light therapy can boost melatonin (褪黑激素) levels, and also serotonin (血清素) in the brain—higher levels of serotonin between nerve connections can have anti-depressive effects. But as appealing as that sounds, Lieberman says there isn't solid evidence behind it. "Light therapy is not a fake, but the evidence is not that strong," he says. "But since it's not invasive, it also isn't harmful—except perhaps to your budget." So if you're not feeling your usual cheerful self this winter, see your doctor. If he doesn't diagnose you with SAD, try adding some physical activity to your day and getting regular sleep. And remember that spring is just a few months away.
