Biologists believe that love is fundamentally a biological rather than a cultural construct, because the capacity for love is found in all human cultures and similar behavior is found in some other animals.In humans the purpose of all the desire is to focus attention on the raising of offspring. Children demand an unusual amount of parenting, and two parents are better than one. Love is a signal that both partners are committed, and makes it more likely that this commitment will continue as long as necessary for children to reach independence. But what does science have to say about the notion of love at first sight?In recent years the ability to watch the brain in action has offered a wealth of insight into the mechanics of love. Researchers have shown that when a person falls in love, a dozen different part of brain work together to release chemicals that trigger feelings of euphoria, bonding and excitement. It has also been shown that the unconditional love between a mother and a child is associated with activity in different regions of the brain from those associated with pair-bonding love.Passionate love is rooted in the reward circuitry of the brain-the same area that is active when humans feel a rush from cocaine. In fact, the desire, motivations and withdrawals involved in love have a great deal in common with addiction. Its most intense forms tend to be associated with the early stages of a relationship, which then give way to a calmer attachment form of love one feels with a long term partner.What all this means is that one special person can become chemically rewarding to the brain of another. Love at first sight, then, is only possible if the mechanism for generating long﹣term attachment can be triggered quickly. There are signs that it can be. One line of evidence is that people are able to decide within a second how attractive they find another person. This decision appears to be related to facial attractiveness, although men may favor women with waist-to-hip ratio of 0.7, no matter what their overall weight is. (This ratio may indicate a woman's reproductive health. )Another piece of evidence comes from work by a psychologist at Ben-Gurion University, who found in a survey that a small percentage (11%) of people in long-term relationships said that they began with love at first sight. In other words, in some couples the initial favorable impressions of attractiveness triggered love which sustained a lengthy bond. It is also clear that some couples need to form their bonds over a longer period, and popular culture tells many tales of friends who become lovers.One might also assume that if a person is looking for a partner with traits that cannot be quantified instantly, such as compassion, intellect or a good sense of humor, then it would be hard to form a relationship on the basis of love at first sight. Those more concerned with visual appearances, though, might find this easier. So it appears that love at first sight exists, but is not a very common basis for long-term relationships.1. When a person falls in love,____.A.he feels as if he were addicted to cocaine.B.he will be committed to the beloved as long as necessary.C.he will experience complex feelings brought on by different regions of his brain.D.he will experience a calmer attachment form of love before he feels the extreme love.2. We can infer from the passage that____.A.pair-bonding love comes from a long stable friendship.B.the mechanism for creating long-term attachment ensures love at first sightC.it is impossible for those ordinary-looking people to fall in love at first sight.D.men may be attracted by a girl whose figure suggests her admirable reproductive capacity.3. The underlined word " traits" in the last paragraph probably means____.A.characteristicsB.something typical in your temperC.particular quantities in your personalityD.attitudes that show your moral standards4. Which of the following may be the best title of the passage?A.The stages of passionate loveB.The science of love at first sightC.The biological construct of pair-bondingD.The mechanism for generating long-term love.

In the past, falling oil prices have given a boost to the world economy, but recent forecasts for global growth have been toned down(不容乐观), even as oil prices sink lower and lower. Does that mean the link between lower oil prices and growth has weakened?Some experts say there are still good reasons to believe cheap oil should heat up the world economy. Consumers have more money in their pockets when they're paying less at the pump. They spend that money on other things, which stimulates the economy. The biggest gains go to countries that import most of their oil like China, Japan, and India. But doesn't the extra money in the pockets of those countries' consumers mean an equal loss in oil producing countries, cancelling out the gains? Not necessarily, says economic researcher Sara Johnson. "Many oil producers built up huge reserve funds when prices were high, so when prices fall they will draw on their reserves to support government spending, and subsidies(补贴) for their consumers."But not all oil producers have big reserves. In Venezuela, collapsing oil prices have sent its economy into free-fall. Economist Carl Weinberg believes the negative effects of plunging oil prices are overwhelming(压垮) the positive effects of cheaper oil. The implication(牵连) is a sharp decline in global trade, which has plunged(暴跌) partly because oil-producing nations can't afford to import as much as they used to. Sara Johnson acknowledges that the global economic benefit from a fall in oil prices today is likely lower than it was in the past. One reason is that more countries are big oil producers now, so the nations suffering from the price drop account for a larger share of the global economy.Consumers, in America at least, are acting cautiously with the savings they're getting at the gas pump, as the memory of the recent great recession(经济衰退) is still fresh in their mind. And a number of oil-producing countries are trimming their gasoline subsidies and raising taxes, so the net savings for global consumers is not as big as the oil price plunge might suggest. What does the author mainly discuss in the passage?A. The reasons behind the plunge of oil prices.B. Possible ways to stimulate the global economy.C. The effect of falling oil prices on consumer spending.D. The impact of cheap oil on global economic growth.Why do some experts believe cheap oil will stimulate the global economy?A. Manufacturers can produce consumer goods at a much lower cost.B. Consumers will spend their saving from cheap oil on other commodities.C. Lower oil prices have always given a big boost to the global economy.D. Oil prices may rise or fall but economic laws are not subject to change.What happens in many oil-exporting countries when oil prices go down?A. They use their money reserves to back up consumption.B. They suspend import of necessities from overseas.C. They reduce production drastically to boost oil prices.D. They try to stop their economy from going into free-fall.How does Carl Weinberg view the current oil price plunge?A. It is one that has seen no parallel in economic history.B. It still has a chance to give rise to a boom in the global economy.C. Its negative effects more than cancel out its positive effects.D. Its effects on the global economy go against existing economic laws.Why haven't falling oil prices stimulated the global economy as they did before?A. People are not spending all the money they save on gas.B. The global economy is likely to undergo another recession.C. Oil importers account for a larger portion of the global economy.D. People the world over are afraid of a further plunge in oil prices.
How about trying something unusual?A试一试与众不同的工作怎么样B试一试工作的不同寻常C关于与众不同的工作怎么样
Does your mouth water when you think of cookies,burgers and French fries?Many people prefer junk food to healthy food because they develop a taste for it.Processed,baked,and fried foods often contain a high amount of trans fats(反式脂肪). Food companies and restaurants choose to use trans fat oils because they're cheap and they make baked goods last longer.They also improve the taste of food.Trans fats became very popular in the second half of the 20th century.This is around the time when butter got a bad name for its cholesterol (胆固醇) levels. Today doctors know how dangerous trans fats can be.Trans fats raise bad cholesterol and lower the good cholesterol that your body needs.Fatty foods do more than cause obesity.Trans fats build up in the body and block blood flow to the heart.People whose diet contains a high percentage of trans fats are at risk of developing heart disease. In countries such as the US and Canada there are new government restrictions on food production.Food makers must attach a Nutrition Fact label to their products.These list daily recommendations and detail all the ingredients in a product,including trans fats if they're used.Even fast-food chains such as McDonald's are being forced to change their recipes as people become more health-conscious.In Europe,food producers have voluntarily started using labels that clearly show how healthy each product is according to a simple rating system. Reading the list of ingredients on the label is a good way of avoiding dangerous ingredients like trans fats.Another way is to avoid eating out,especially in fast-food restaurants.Also,when shopping try to buy your food in the fresh-food section and limit the amount of processed food you buy.The choices you make now will affect you for the rest of your life.The healthier your diet is now,the longer and healthier your life will be.(1)Why do people like to eat junk food? ____ A.Because of its price.B.ecause of its trend.C.Because of its taste.D.Because of its color.(2)Why are trans fat oils used in food production? ____ A.They are good for health.B.They taste better than butter.C.They can last longer than butter.D.They can lower the cost of production.(3)How does the author support the underlined statement in Paragraph 3? ____ A.By telling stories.B.y presenting statistics.C.By making comparisons.D.By providing explanations.(4)What does the underlined word"These"in Paragraph 4 refer to? ____ A.The labels.B.The recipes.C.The products.D.The restrictions.(5)What does the last paragraph mainly talk about? ____ A.The ways to do shopping.B.The tips on healthy diets.C.The influence of tans fats.D.The role of food ingredients.
Coping with Climate Change What we have learned so far about climate changes is affecting our global environment. Studies show that it adversely affects human and natural systems by reducing biodiversity, impairing biological and chemical circles and making it more difficult to restore degraded ecosystems. Climate is not the only factor in the deterioration of natural systems. We are making big changes to the landscape, altering land use and land cover in major ways. These changes combined present a challenge to environmental management. Adaptive management is a scientific approach to managing the adverse impacts of climate and landscape change.Nature and Impacts of Climate Change Every week it seems there is an article about global warming in the news media. It may be difficult for some to grasp the big picture of the issue, but in general, climate change has already or is expected to ・ increase temperatures, particularly in the interior of continents, toward the poles and in winter; ・ boost precipitation(降水量) in wetter areas and suppress precipitation in drier areas; ・ increase rain and decrease snow; ・ lessen peak spring runoff and cause more even year-round flow of water, thereby reducing water availability during summer irrigation and navigation seasons; ・ increase evaporation of water during the summer; ・ enhance the likelihood of lower mean lake levels, drier wetlands, and water shortages, particularly in mountain regions; ・ raise the frequency and magnitude of extreme weather events, such as hurricanes, tornadoes, and floods; ・ raise global sea levels, causing some populated coastal areas to become inundated(被淹没的) ; ・ reduce the extent and duration of Arctic sea ice with adverse consequences for marine mammals; ・ increase the losses of glaciers in middle and equatorial latitudes, including premier mountain ecosystems such as Glacier National Park in Montana. Global average temperature had increased by about 0.6℃ over the past 100 years, with a major warming upswing in the 1970s. Warming is the result, in part, of rapid increases in emissions of greenhouse gases(GHG), particularly carbon dioxide(CO2), which is a byproduct of the combustion of fossil fuels, such as coal, oil, and natural gas, used for power generation and transportation. When global temperatures rise and precipitation patterns change, it is expected there will be consequences on ecosystems, such as an increase in the spread of exotic species, redistributing of plants, animals, energy, water and nutrients; alteration of natural processes and the structure and function of ecosystems. Northerly latitudes are particularly vulnerable to climate change. The Arctic Council, an intergovernmental forum for Arctic nations and indigenous people, reported that the northern ice cap is warming at twice the global rate and the Arctic region is expected to warm a two or three times the rate for rest of the world. Arctic warming will have serious consequences on human and ecology.Nature and Impacts of Landscape Change Landscape change results from natural disturbances and human activities. Natural disturbances include fire, windstorms, avalanches, landslides, tree fall, floods, and insect epidemics. Human activities causing landscape change include conversion of forestland to agriculture, drainage of wetlands, and forest fragmentation form road construction and timber harvesting. Human activities often have a more significant effect on landscapes than natural disturbances because they alter the availability of energy, water, and nutrients to ecosystems; increase the spread of exotic species; accelerate natural processes of ecosystem change; and adversely affect the structure and functioning of ecosystems. Human-induced landscape change has accelerated during the past several decades because of rapid population and economic growth, particularly in countries such as China, India, and Brazil. Landscape change had contributed to a dramatic 1.000-fold increase in species .extinctions over the past 400 years. On a global basis, nearly 1.2 million km2 of forest and woodland and 5.6 million km2 of grassland and pastureland have been converted to other uses. During the last three centuries, 12 million km2 of cropland were lost. Between 1982 and 1997, 121000 km2 of non-federal land were urbanized in the United States. More than 90 percent of the land in the lower 48 states has been logged, plowed, mined, grazed, paved, or otherwise modified from previous conditions. Human-induced landscape change significantly affects wildlife. For example, between 1970 and 2000, rural residential development in the Montana and Wyoming portions of the Greater Yellowstone Ecosystem increased 400 percent. Consequently, current and potential grizzly bear habitat on private lands in the ecosystem has been degraded and fragmented. Double-digit growth in residential subdivisions adjacent to the National Elk Refuge in Jackson, Wyoming, has diminished winter range for the 10000 elk that use the refuge and displaced corridors that elk use to reach summer range in Yellowstone and Grand Teton National Parks. Another example of significant impacts from landscape change is the Crown of the Continent Ecosystem. This ecosystem covers the Rocky Mountains in British Columbia and Alberta, Canada, and western Montana, United States. Here are some specifics: ・ Most old-growth forests that once existed outside of protected parks and wilderness areas have been harvested. ・ Many rivers in the region have been altered by hydroelectric power development. ・ Significant farm, ranch, and forest acreage has been converted to homes and commercial developments. ・ Lakes and streams have been polluted by agricultural and urban runoff. ・ Fish and wildlife habitats have been degraded. ・ Active and proposed energy developments threaten protected areas. ・ Large areas have been invaded by normative species. The desire to preserve the outstanding wildlife( especially large carnivores) and environmental amenities(舒适 ) from the negative effects of rapid economic growth and development in the northern Rocky Mountain region prompted creation of the Yellowstone to Yukon Conservation Initiative. The initiative involves 300 conservation organizations and covers an area larger than the states of California and Texas combined, including the Greater Yellowstone and Crown of the Continent Ecosystem.Coping with Climate and Landscape Change Although climate and landscape change has positive effects on human and natural system, it is expected to have many adverse impacts that deserve attention. Ecosystems have an inherent capacity to resist climate and landscape change, known as ecological resilience(复原能). When this capacity is exceeded, the ecosystem can change in ways that may not be socially and ecologically acceptable. So what can be done Mitigation strategies can reduce ecosystem vulnerability. Mitigation strategies are actions to prevent, reduce, or slow climate and/or landscape change. The Kyoto Protocol to the United Nations Framework Convention on Climate Change, which took effect in February 2005, is a prime example of a climate change mitigation strategy. The protocol commits 36 industrialized countries to curb GHG emissions, especially CO2. Limiting increases in global temperature by 2℃ would require keeping atmospheric concentrations of CO2 below 400 parts per million(ppm). Current concentrations are about 375 ppm. Benefits from the Kyoto Protocol may be limited because it does not include some developed countries, which emit substantial GHGs, and developing countries where rapid population and economic growth is expected to dramatically increase GHG emissions. Other mitigation: strategies include increasing the use of alternative energy sources and technologies (clean coal, renewable energy, ethanol, hybrid vehicles, and nuclear power). Although the United States did not sign the Kyoto Protocol, 28 states have programs to curb CO2 emissions, and at least 166 U. S. cities have agreed to apply the Kyoto emission reduction standards to their communities. Other initiatives, like the Apollo Alliance, bring together labor unions, environmental and business groups, and activist: organizations with the mission of sharply reducing U. S. dependence on fossil fuels. The alliance is seeking ways to do the following: ・ power the economy with hydrogen produced from renewable energy resources; ・ implement green construction codes; ・ revitalize urban centers to reduce urban sprawl; ・ determine how industry can store rather than emit carbon into the atmosphere. The Apollo Alliance expects to invest 300 billion in new energy technologies and energy conservation over 10 years as a way to eliminate U. S. dependence on foreign oil and create millions of good-paying jobs. There funds would be raised using tax incentives, public bonds, capital strategies, and other mechanisms.What is the influence of human activities on landscapes A. They provide more energy, water and nutrients to ecosystems.B. They maintain the balance of ecosystems.C. They affect the structure and functioning of ecosystems in a negative way.D. They curb the spread of exotic species.

Americans experience more food recalls (召回) today than they did five years ago, especially when it comes to meat and poultry (家禽). Meat and poultry recalls increased by two-thirds from 2013 to 2018, while food recalls overall went up 10%, according to the report recently published by the U.S. Public Interest Research Group.Meanwhile, the U.S. Centers for Disease Control and Prevention estimates (估计) 48 million people get sick, 128,000 are hospitalized and 3,000 die from food-borne disease each year in the U.S. "We are looking for the farm-to-fork preventative solutions," said Adam Garber, the research group's consumer watchdog. "By doing that, we can protect people's health."Over the five-year period, poultry posted the most recalls (168), followed by beef (137) and pork (128). The report shows the most serious meat recalls are on the rise. Among meat and poultry, the number of Class I recalls has increased by 83%, nearly doubling. Class I, the most serious of the recalls, is issued when there is a reasonable probability that the food will cause health problems or death.53. When would Class I recalls be issued?A. When the food is likely to cause health problems or death.B. When there are too many complaints from customers.C. When the food problem lasts for five years.D. When the product quality is below standard.
The Harry Potter series, written by J.K. Rowling, is perhaps the most popular set of novels of the modern era. With seven books and many successful films to its name, the series has gathered about 15 billion dollars in sales. How did the series become so popular? The reason can be broken down into several areas.The first book in the series was rejected 12 times before it was picked up by Bloomsbury—a small publisher in England. So receiving this contract was Rowling's first step to success. However, getting a book contract does not ensure the success of a book. The story was soon loved by children and adults alike. In light of this, Bloomsbury Publishing published a second version of the books with “adult” (less colorful and more boring) book covers. This made it easier for a full range of ages to enjoy the series.Another factor that worked like a charm was that the publisher and Rowling herself, through the books, conducted midnight releases, promotions, and pre-ordering more readers. Customers who feared that their local bookstore would run out of copies responded by pre-ordering over 700,000 copies before the July 8, 2000 release.What does the underlined word “releases” (Para. 3) mean?A. The activity that frees or expresses energy or emotion.B. The announcement about the book’s publishing information.C. The sales of books that is available only at midnight.

The increase in international business and in foreign investment has created a need for executives with knowledge of foreign languages and skills in cross-cultural communication. Americans, however, have not been well trained in either area and, consequently, have not enjoyed the same level of success in negotiation in an international arena as have their foreign counterparts. Negotiating is the process of communicating back and forth for the purpose of reaching an agreement. It involves persuasion and compromise, but in order to participate in either one, the negotiators must understand the ways in which people are persuaded and how compromise is reached within the culture of the negotiation. In many international business negotiations abroad, Americans are perceived as wealthy and impersonal. It often appears to the foreign negotiator that the American represents a large multi-million-dollar corporation that can afford to pay the price without bargaining further. The American negotiator’s role becomes that of an impersonal supplier of information and cash. In studies of American negotiators abroad, several traits have been identified that may serve to confirm this stereotypical perception, while undermining the negotiator’s position. Two traits in particular that cause cross-cultural misunderstanding are directness and impatience on the part of the American negotiator. Furthermore, American negotiators often insist on realizing short-term goals. Foreign negotiators, on the other hand, may value the relationship established between negotiators and may be willing to invest time in it for long-term benefits. In order to solidify the relationship, they may opt for indirect interactions without regard for the time involved in getting to know the other negotiator. Clearly, perceptions and differences in values affect the outcomes of negotiations and the success of negotiators. For Americans to play a more effective role in international business negotiations, they must put forth more effort to improve cross-cultural understanding.
