33If 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

阅读理解AThere are an extremely large number of antsworldwide. Each individual (个体的) ant hardly weigh anything, but put together they weigh roughly the same as all of mankind. They also live nearly everywhere, except on frozen mountain tops and around the poles.Foranimals their size, ants have been astonishingly successful, largely due to their wonderfulsocial behavior.In colonies (群体) that range in size from a few hundred to tens of millions, they organize their lives with a clear division of labor. Even more amazing is how they achievethis level of organization. Where we use sound and sight to communicate, ants dependprimarily on pheromone (外激素), chemicals sent out by individuals and smelled or tastedby fellow members of their colony. When an ant finds food, it produces a pheromone that will lead others straight to where the food is. When an individual ant comes under attack or is dying, it sends out an alarm pheromone to warn the colony to prepare for a conflict as a defense unit.In fact, when it comes to the art of war, ants have no equal. They are completely fearless and will readily take on a creature much larger than themselves, attacking in large groups and overcoming their target. Such is their devotion to the common good of the colony that not only soldier ants but also worker ants will sacrifice their lives to help defeat an enemy.Behaving in this selfless and devoted manner, these little creatures have survived on Earth, for more than 140 million years, far longer than dinosaurs. Because they think as one, they have a collective (集体的) intelligence greater than you would expect from itsindividual parts.21.We can learn from the passage that ants are ____________.A. not willing to share foodB. not found around the polesC. more successful than all other animalsD. too many to achieve any level of organization22.Ants can use pheromones for______.A. escape B. communication C. warning enemies D. arranging labor23.What does the underlined expression "take on" in Paragraph 3 mean?A.

D.He painted special pictures for her.27.According to paragraph 4.the paralyzed girl .A.gradually recovered and walkedB.eventually became a unique painterC.was sent home and never seen againD.sent him a picture painted with her mouth28.What message does the passage mainly convey?A.It’s better to give than to receive.B.Love can sometimes bring great results.C.Volunteering is a worthwhile thing to do.D.A sick person should not focus on his disease.CThe hit movie Finding Nemo follows a clownfish from the Great Barrier Reef. In real life, clownfish are among the thousands of colorful sea creatures that call the Great Barrier Reef home.Stretching l,250 miles along Australia' s northeastern. coast, the Great Barrier Reef is the longest coral reef in the world.A coral reef is a living underwater structure. But these days, the Great Barrier Reef has found itself in trouble.Overfishing, pollution, and high temperatures are harming its health. That's whythe government in Australia is trying to help rescue the reef.Underwater GardenWhile coral may look like a plant, it is actually made up of tiny sea animal.Those sea animals are called coral polyps.As polyps die, they leave hard.shells behind. Other polyps grow on top of the shells.Over thousands of years, they form a coral reef in warm water that is not very deep.In many ways, the Great Barrier Reef resembles an underwater garden. Coral can be hard or soft.It forms in different colors and in strange shapes.Some coral looks like hardened brains. Other coral looks like fans and lettuces.The reef bursts with schools of tropical fish, dashing among gaps in the coral. The reef supplies food. and. shelter to creatures living in and around the coral. Turtles, sharks, sea horses, and crabs are among its many inhabitants.Helping HumansWhile the reef is important to ocean life, it helps humans, too. People rely on the reef for both food and jobs. It also provides medicine used to treat disease. Each year, the Great Barrier Reef contributes about 975 million to the economy through tourism and fishing.Stressed OutIs it surprising, then, that the Great Barrier Reef is under too much stress? Fishing nets and ships break off sections and damage the reef. Air and water pollution are also doing harm. At the same time, warmer sea temperatures have caused coral bleaching(漂白) on half of the reef. The high temperatures cause the coral to turn white, often killing it.Reef RescueIn an effort to help save the reef, the government has limited fishing to two thirds of it. That plan increases the number of "green zones.”Those are areas that are off -limits to fishermen and boats. However, tourists and researchers can still visit them. Many fishermen are upset about the plan because they rely on the reef for jobs.The Australian government says that its plan will help keep the reef safe from some threats. "It is very important that we give B reef proper protection for the future," said one government official. The reef is Australia' s greatest natural treasure.29.Which of the following is not a creature that lives in the Great Barrier Reef?A. Coral polyps. B. Turtles. C. Sea horses. D. Whales.30.Which section describes the problem in this passage?A. " Underwater Garden" B. " Helping HumansC.“Stressed Out" D.“Reef Rescue"31.What picture can the reader get from the underlined sentence The reef bursts with schools of tropical fish, dashing among gaps in the coral. in Paragraph 6?A. Many fish quickly moving through the coral.B. Fish moving toward the center, or target, of the coral.C. Structured, orderly groups of young fish without a clear path.D. Fish exploding when they come into contact with gaps in the coral.32.What is this passage mostly about?A. The causes of reef problems an possible solutions.B. Coral bleaching, which causes the reef to turn white.C. The history of tourism to the Great Barrier Reef.D. Overfishing and higher temperatures.DTexting pedestrians arena' t just an annoyance to their fellow walkers, but something dangerous to themselves.“1 was checking emails while walking to work this morning," said Wilbert van den Hoorn.“But it has a serious influence on the safety of people who type or read text while walking."Anecdotes back him up.A tourist from Taiwan walked off a port near Melbourne last month while checking Face book-bringing an abrupt, and icy end to a penguin- watching visit. Another shopper in the U.S. was too addicted to his mobile phone to notice the fountain ahead! walking straight into it.And as mobile-phone use has grown-to about 77% of the world's population, the study says-so has the number of phone-related accidents.The number of U.S.emergency-room visits linked to phone use on the move doubled to as many as l,500 between 2005 and 2010, an Ohio State University study recently showed.Authorities world-wide have taken note.Signs on Hong Kong's subway system advise passengers in three languages to keep their eyes off their phones.Police and transport authorities have also warned the danger in Singapore, where the Straits Times newspaper ranked it as No.2 Bad Habit"' due to the rising number of road deaths.Some U.S.states, including New York and Arkansas, are even considering bans on this act.The Australian study used 26 volunteers, a third of whom admitted having hit objects while texting.They were fitted with different equipment in different parts of their body, and asked to walk 8.5 meters three times-once without a phone, once while reading a text and once while writing a text-while eight cameras captured the action.Volunteers using the phone walked slower and with shorter steps (and slowest of all when typing), and! more seriously, they locked their arms and elbows in-like “robots", in the researchers' words.That forced their heads to move more, throwing them off balance.“In a pedestrian environment, inability to maintain a straight path would be likely to increase potential for hits, falls and traffic accidents," said Mr.van den Hoorn.“The best thing to do is to step aside and stop, or keep off the phone."33.Which of the following about” Texting pedestrians" is WRONG?A.People who type while walking.B.People who phone while walking.C.People who text while walking.D.People who read text message while walking.34.The writer uses the two examples in Paragraph 3 to showA.the advantages of mobile phonesB.the use of mobile phones in waterC.the use of mobile phones in a wrong wayD.the popularity of mobile phones35.What is New York and Arkansas' attitude to texting pedestrians?A.Considering forbidding their acts.B.Ranking it as” No.l Bad Habit".C.Setting up signs to warn them.D.Equipping them with advanced machines.36.Why are texting pedestrians likely to hit or fall according to the passage?A.They walk too fast.B.They lock their arms and elbows.C.They are out of balance.D.They walk with longer steps.37.What is the best title for the passage?A.Text message or e-mail only?B.Ways to avoid fallsC.Mobile phones for entertainmentD.Safety or text message?

Artificial Intelligence (AI) has been making significant inroads into the field of education in recent years. It has the potential to revolutionize the way students learn and teachers teach.One of the key applications of AI in education is personalized learning. Through the use of machine learning algorithms, AI systems can analyze a student's performance, learning style, and preferences. Based on this analysis, they can provide customized learning materials and paths. For example, if a student is struggling with a particular concept in math, the AI-powered learning platform can identify the areas of weakness and offer targeted practice problems, video tutorials, and additional resources. This personalized approach ensures that each student receives the support they need at their own pace, rather than being forced to follow a one-size-fits-all curriculum.Another important aspect is intelligent tutoring systems. These are computer-based systems that can act as virtual tutors. They can answer students' questions, provide instant feedback on assignments, and guide students through complex topics. Intelligent tutoring systems are available 24/7, which means students can get help whenever they need it, regardless of time or location. They also adapt to the student's progress, adjusting the level of difficulty as the student masters new skills.AI is also being used to improve assessment in education. Traditional assessment methods, such as exams and quizzes, often provide a limited view of a student's knowledge and skills. AI-enabled assessment tools can analyze a wider range of data, including students' interactions with learning materials, their participation in online discussions, and their performance on practical tasks. This more comprehensive assessment can give teachers a more accurate understanding of a student's strengths and weaknesses, allowing for more targeted instruction.However, the integration of AI in education also raises some concerns. There are worries about data privacy, as AI systems collect and analyze large amounts of student data. There are also questions about the role of human teachers in an AI-driven educational environment. Will teachers be replaced by machines? In fact, most experts agree that AI is not a substitute for human teachers but rather a tool to enhance the teaching-learning process.Despite these concerns, the future of AI in education looks promising. As technology continues to advance, we can expect to see even more innovative applications that will transform education for the better.(1) (单选题) What is one of the main applications of AI in education?A. Creating a standardized curriculum for all students.B. Providing personalized learning experiences.C. Replacing human teachers with virtual tutors.D. Limiting students' access to learning materials.

When it came to concealing his troubles, Tommy Wilhelm was not less capable than the next fellow. So at least he thought, and there was a certain amount of evidence to back him up. He had once been an actor—no, not quite, an extra—and he knew what acting should be. Also, he was smoking a cigar, and when a man is smoking a cigar, wearing a hat, he has an advantage: it is harder to find out how he feels. He came from the twenty-third floor down to the lobby on the mezzanine to collect his mail before breakfast, and he believed — he hoped — that he looked passably well: doing all right. It was a matter of sheer hope, because there was not much that he could add to his present effort. On the fourteenth floor he looked for his father to enter the elevator; they often met at this hour, on the way to breakfast. If he worried about his appearance it was mainly for his old father's sake. But there was no stop on the fourteenth, and the elevator sank and sank. Then the smooth door opened and the great dark-red uneven carpet that covered the lobby billowed toward Wilhelm's feet. In the foreground the lobby was dark, sleepy. French drapes like sails kept out the sun, but three high, narrow windows were open, and in the blue air Wilhelm saw a pigeon about to light on the great chain that supported the marquee of the movie house directly underneath the lobby. For one moment he heard the wings beating strongly.Most of the guests at the Hotel Gloriana were past the age of retirement. Along Broadway in the Seventies, Eighties, and Nineties, a great part of New York's vast population of old men and women lives. Unless the weather is too cold or wet they fill the benches about the tiny railed parks and along the subway gratings from Verdi Square to Columbia University, they crowd the shops and cafeterias, the dime stores, the tearooms, the bakeries, the beauty parlors, the reading rooms and club rooms. Among these old people at the Gloriana, Wilhelm felt out of place. He was comparatively young, in his middle forties, large and blond, with big shoulders; his back was heavy and strong, if already a little stooped or thickened. After breakfast the old guests sat down on the green leather armchairs and sofas in the lobby and began to gossip and look into the papers: they had nothing to do but wait out the day. But Wilhelm was used to an active life and liked to go out energetically in the morning. And for several months, because he had no position, he had kept up his morale by rising early: he was shaved and in the lobby by eight o'clock. He bought the paper and some cigars and drank a Coca-Cola or two before he went in to breakfast with his father. After breakfast—out, out, out to attend to business. The getting out had in itself become the chief business. But he had realized that he could not keep this up much longer, and today he was afraid. He was aware that his routine was about to break up and he sensed that a huge trouble long presaged(预感)but till now formless was due. Before evening, he'd know.Nevertheless he followed his daily course and crossed the lobby.Rubin, the man at the newsstand, had poor eyes. They may not have been actually weak but they were poor in expression, with lacy lids that furled down at the corners. He dressed well. It didn't seem necessary—he was behind the counter most of the time—but he dressed very well. He had on a rich brown suit; the cuffs embarrassed the hairs on his small hands. He wore a Countess Mara painted necktie. As Wilhelm approached, Rubin did not see him; he was looking out dreamily at the Hotel Ansonia, which was visible from his corner, several blocks away. The Ansonia, the neighborhood's great landmark, was built by Stanford White. It looks like a baroque palace from Prague or Munich enlarged a hundred times, with towers, domes, huge swells and bubbles of metal gone green from exposure, iron fretwork and festoons. Black television antennae are densely planted on its round summits. Under the changes of weather it may look like marble or like sea water, black as slate in the fog, white as tufa in sunlight. This morning it looked like the image of itself reflected in deep water, white and cumulous above, with cavernous distortions underneath. Together, the two men gazed at it. Then Rubin said, “Your dad is in to breakfast already, the old gentleman.”“Oh, yes？Ahead of me today？”“That's a real knocked-out shirt you got on,” said Rubin.“Where’s it from, Saks？”“No, it’s a Jack Fagman—Chicago.” Even when his spirits were low, Wilhelm could still wrinkle his forehead in a pleasing way. Some of the slow, silent movements of his face were very attractive. He went back a step, as if to stand away from himself and get a better look at his shirt. His glance was comic, a comment upon his untidiness. He liked to wear good clothes, but once he had put it on each article appeared to go its own way. Wilhelm, laughing, panted a little; his teeth were small; his cheeks when he laughed and puffed grew round, and he looked much younger than his years. In the old days when he was a college freshman and wore a beanie(无檐小帽)on his large blonde head his father used to say that, big as he was, he could charm a bird out of a tree. Wilhelm had great charm still.“I like this dove-gray color,” he said in his sociable, good-natured way. “It isn’t washable. You have to send it to the cleaner. It never smells as good as washed. But it’s a nice shirt. It cost sixteen, eighteen bucks.”【小题1】Wilhelm hoped he looked all right on his way to the lobby because he wanted to________.A．leave a good impressionB．give his father a surpriseC．show his acting potentialD．disguise his low spirit【小题2】Wilhelm had something in common with the old guests in that they all ________.A．lived a luxurious lifeB．liked to swap gossipsC．idled their time awayD．liked to get up early【小题3】How did Wilhelm feel when he was crossing the lobby(Para.2)?A．He felt something ominous was coming.B．He was worried that his father was late.C．He was feeling at ease among the old.D．He was excited about a possible job offer.【小题4】What can we learn from the author's description of Wilhelm's clothes?A．His shirt made him look better.B．He cared much about his clothes.C．He looked like a comedian in his shirt.D．The clothes he wore never quite matched.
