28If you’ve ever looked at the ingredients list while grocery shopping, chances are you’ve seen the term “natural flavors”. But have you taken a 26 to consider what these natural flavors actually are?Most of us might think that “natural flavors” are, well, naturally good for us. A recent study in the journal Appetite found that when the word “natural” appears on packaging, people 27 that the food within is indeed healthier. In truth, natural flavors do not 28 much, at least chemically speaking, from their flavor-boosting 29: artificial flavors. Both can be made in a lab by trained flavorists, but artificial flavors use chemicals to give a product a 30 smell or taste.Natural flavors come from plant or animal 31, like fruit, vegetable, meat, fish or milk that is then processed or refined in some way. In short, natural flavors are 32 from plants and animals to create specific flavors for processed foods. But that does not 33 make it easier to tell what is really in your food. Because the Food and Drug Administration (FDA) has not 34 the term, companies can use it to refer to pretty much anything derived from a plant or animal. And natural flavors can also include a variety of chemical additives, such as preservatives. The FDA doesn’t require companies to reveal what additional chemicals a specific item 35.So if you want to know for certain what you’re getting with your groceries, you might want to stick to the farmer’s market.A、acknowledgeB、chanceC、containsD、counterpartsE、definedF、differG、especiallyA.extractedB.impliesC.necessarilyD.particularE.perceiveF.secondG.sourcesH.strange

Most fatal accidents involve a disproportionately ( 不成比例的 ) high number of men unden the age of 25 . A report on young driver research prepared last year by Monash University - accident research centre found that , in 1990 and 1991 , almost a bird of the people killed in road crashes were drivers under 25 . Yet this age group represents only 14 percent of the population . The report , which also updated a review of international literature about , among other things , driver training , also reached what many would consider a startling cond usi on : Training and education pro no pally in the US do not appear to reduce younger drivers risk of crashing The Monash University researchers looked at the crash information from New South Wales for 1986 to 1990 from Victoria for 1984 to 1990 and from South Australia for 1986 to 1990 . The only Australian evidence which possibly indicates that counter - measures targeted specifically at young beginner drivers have been effective comes from evaluations of zero blood alcohol concentration legislation . The Monash researchers also looked the US road - crash in 九番 ation for 1989 on 6.6 million police - reported crashes involving fatal flies injuries and motor vehicle damage . The researchers looked at a sample of 44 000 crashes . The conclusion was that the available literature gives a pessimistic view of the effectiveness of driver training and education reflected in the In a blini ty to produce drivers safer than those who have not been trained . The Monash University s report about young drivers con duded that younger drivers were more likely to take risks at night younger men were more likely to take risks than younger women but younger women appeared to have greater skills deli den cy . Overall the researchers concluded that I appears that vehicle - control skills improve rapidly with increasing experience but that their development is still incomplete after one or two years and possible after considerably longer periodsA place where white has been made to representAll that is good and pure and fine and decent.Harsh was among the few “keenly interested in the welfare of their race".

Daniel Olin was 11 years old when his parents moved to Canada. He liked his new school and made friends there, but then things at home started to change. His mum and dad began to argue and the arguments got worse and worse until one day, Daniel's mum left. With his father working long hours, Daniel felt very lonely and very unhappy. He wanted to escape, to run away. And that’s what he did.Very early one terribly cold morning when the snow was deep on the ground, he packed a bag with some clothes, some chocolate and a map of Canada and set off to a forest. He ran and ran until he could hardly breathe.His feet were heavy with the snow but he still walked on through deep snow, not even watching where he was going.Then, disaster struck. A rock hidden by the deep snow caught his feet and Daniel fell to the ground. He had broken the bone. He was very cold and was starting to feel tired, but he knew that if he fell asleep in the snow, he would certainly die from the cold.A tree shook ahead. From within the branches(树枝), a pair of yellow eyes watched Daniel. The puma (美洲狮) had been following him. A puma is a large wild cat with claws that could tear Daniel into pieces. But instead of moving in for the kill, the puma walked up to Daniel and lay across his chest, arms and legs. Daniel was too frightened to move, but soon the warmth of the animal reached Daniel and he began to feel better. From time to time, the puma pressed his muzzle (鼻) against Daniel and rocked his head gently. Clearly, the puma knew that Daniel must not fall asleep. This animal should have been a real danger to Daniel and yet the boy began to feel safe.

More than 10 million Chinese cultural relics（遗物）have been lost overseas，most of which were stolen and illegally shipped out of China during the times of war before 1949.About 1.67 million pieces are housed in more than 200 museums in 47 countries，which account for 10 percent of all lost Chinese cultural relics，and the rest are in the hands of private collectors. Most of these treasures are owned by museums or private collectors in the United States，Japan，some European countries and Southeast Asian countries.There are more than 23，000 pieces in the British Museum，most of which were stolen or bought for pennies more than 100 years ago. The major method of recovering these national treasures is to buy them back.In some cases，private collectors donated the relics to the government.Also the government can turn to official channels（渠道）to demand the return of the relics. In 2003，a priceless bronze pig head dating from the Qing Dynasty was returned to its home in Beijing after it was removed by the Anglo-French Allied Forces over 140 years ago.Stanley Ho donated 6 million yuan to buy it back from a US art collector and then donated it to the Poly Art Museum in Beijing. Although buying-back is the most feasible way to recover the lost treasures，limited funding is always a big headache. In recent years， the Chinese government has put more effort into recovering the precious cultural relics lost overseas. It has started a national project on the recovery of the treasures and has set up a database collecting relevant information. It has signed several international agreements with many countries on this matter，and is also looking for international cooperation to recover the relics by working closely with several international organizations.（1）What is the passage mainly about？ ____ A.

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.

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. [共5题](1)What kind of manager is needed in present international business and foreign investment? [本题2分]A. The man who represents a large multi-million-dollar corporation. B. The man with knowledge of foreign languages and skills in cross-cultural communication. C. The man who is wealthy and impersonal. D. The man who can negotiate with his foreign counterparts.
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.

Nothing healthful should be omitted from the meal because of a (56) dislike.
