The Dorset culture began around eight hundred BC and ranged to cross most of arctic Canada. The Thule, well, they lived in the same area, but about twelve hundred years later. Both groups left some beautiful art behind, really are best evidence that these folks even existed. And although these two cultures lived in the same region, each group approached their art in very different ways.Alright, so the Dorset culture. Archaeologists have unearthed hundreds of Dorset sculptures mostly carve from ivory or bone and sometimes stone. They were mostly small sculptures of animal or human figures. And our best guess is that they were probably used mainly for religious purposes. The main subject of Dorset animal sculptures is the polar bear. Some of these polar bears are represented in naturalistic or realistic ways, but usually, their abstracted or stylized that is to say less realistic. Here is a typical polar bear sculpture. It's carved from ivory, we call these artifacts flying or floating polar bears, because, because they look like the polar bears doing just that flying or floating. Notice the distinctive markings, they seem to mark out the skeleton or joints of the bear.While polar bears were favorite subject, the Dorset created sculptures of other animals too, like seals and caribou which were represented in a more realistic fashion. We speculate that if the Dorset feared or respected a particular animal, they were more likely to present it in a stylized way, like with the polar bear, which, of course, is a large dangerous predator, maybe, it was a way of dealing with their fear. We also have Dorset’s sculptures whose meaning is more allusive. I'm talking about horns with many human faces carved into them. What's remarkable about these sculptures is the variety of facial types in expressions that appear on the single horn. If only the people represented on these artifacts could answer our questions, it tells us whetherthey are ancestors or residents of villager or what.Okay, let's switch to Thule art, which differs from Dorset art in, in some important ways. Interestingly, Thule artwork wasn't generally influenced by the earlier Dorset culture. It seems it would’ve grown out of a separate tradition that originated in Alaska. Thule artwork was most likely used to decorate common objects such as tools with attractive designs, we can't be entirely sure about this. However, we've tried to interpret the symbolic designs into the art. But of course, it's impossible to confirm the accuracy of such interpretations. What we do know is that the Thule people made extensive use of engravings, they drove the small holes and carve lines into various materials. These engravings, engraved patterns, rather, are found on the diverse group of artifacts, things ranging from weapons to jewelry to cones and boxes. Here's some examples. It's hard to see, but most of these objects do have engravings on them. Thule art was more of a graphic art. Uh, more like drawing. Many of their designs are geometric and abstract. Others containing engravings of human and animal figures.For instance, the long skinny object, among left, has a face at the top. We’ve also found the tool handle with hunting and camp scenes carved into it. As far as Thule’s sculpture goes, there is only a few small objects in wooden dowels like the one in the bottom right-hand corner. These have either no facial features or very rudimentary ones, less detailed, less individualized than the faces of Dorset’s sculpture.One scholar has argued that this difference resulted from the nature of Thule’s society which was built around group hunting expeditions on the ocean. This hunting approach required a great deal of cooperation which may have led to a kind of an overall uniformity in their art. And emphasis on commonality rather than individuality, which probably explains why there’re human figures like the faces or had standardized faces that all look similar. The most famous of the few Thule sculptures are the ones of birds in creatures that are part bird and part woman. While the sculpture is probably had some symbolic purpose, patterns of holes were drilled into them too. So, in general compared with artwork of the Dorset, Thule artprobably had a more decorative or utilitarian function.题目1.What is the main purpose of the lecture?A. To examine the extent to which Thule and Dorset art influenced the artwork of other arctic culturesB. To examine how Thule and Dorset designs changed over timeC. To compare and contrast artwork from two ancient arctic culturesD.

It placed more emphasis on religious beliefs than Thule society did.B. It relied on hunting large animals to a greater extent than Thule society did.C. It placed an emphasis on the production of jewelry.D. It was structured to support long ocean expeditions.4.According to the professor, what appears to be the main reason that the Thule engraved holes and lines into their artifacts?A.

the lecture英语作文Title: The Importance of "The Lecture" in Education。
In the realm of education, the lecture has long stood as a cornerstone of traditional teaching methods. Its significance transcends generations and technological advancements, remaining a fundamental tool in imparting knowledge and fostering critical thinking skills. In this essay, we delve into the multifaceted importance of the lecture in education.First and foremost, the lecture serves as a platformfor knowledge dissemination. Through lectures, educators have the opportunity to convey complex ideas, theories, and concepts to a diverse audience of learners. This direct transmission of information from teacher to student facilitates comprehension and lays the foundation for deeper exploration and understanding.Moreover, lectures promote active engagement andinteraction in the learning process. While some may perceive lectures as passive forms of education, they actually encourage students to actively listen, process information, and ask questions. The dynamic exchange between lecturer and audience cultivates a collaborative learning environment where ideas are shared, debated, and refined.Furthermore, lectures play a crucial role in providing context and perspective to academic content. By integrating real-life examples, case studies, and historical contexts into their presentations, educators contextualize abstract concepts, making them more relatable and meaningful to students. This contextual understanding not only enhances comprehension but also encourages critical thinking and application of knowledge.Additionally, lectures offer a structured framework for learning, helping students organize and prioritize information. Through carefully crafted presentations, educators guide learners through a logical sequence of topics, building upon foundational concepts and graduallyintroducing more advanced material. This scaffolding approach supports students' cognitive development and fosters a deeper understanding of the subject matter.Furthermore, lectures provide a sense of continuity and coherence to the curriculum. By presenting key concepts and themes in a systematic manner, educators create a cohesive narrative that connects disparate ideas and disciplines. This holistic approach to learning enables students to make meaningful connections between different areas of study, fostering interdisciplinary thinking and creativity.Moreover, lectures serve as a platform for inspiration and motivation. A captivating lecturer has the power to ignite curiosity, spark imagination, and instill a passion for learning in students. Through compelling storytelling, engaging visuals, and thought-provoking discussions, educators can inspire the next generation of thinkers, innovators, and leaders.In addition to their pedagogical benefits, lectures also offer practical advantages in terms of scalability andaccessibility. With advancements in technology, lecturescan now be recorded, streamed, and accessed remotely, reaching a wider audience beyond the confines of the classroom. This flexibility ensures that education remains inclusive and accessible to all, regardless of geographical or logistical constraints.In conclusion, the lecture remains an indispensabletool in the educator's arsenal, providing a platform for knowledge dissemination, active engagement, contextual understanding, structured learning, continuity, inspiration, and accessibility. While alternative teaching methods and technological innovations continue to emerge, the enduring significance of the lecture in education underscores its timeless value in shaping minds and transforming lives.。

In the lecture, the professor talks about two ways that animals use coloration for protection.The first way is called camouflage. It's like when an animal blends in with its surroundings so that it's really hard for predators to spot them. For example, there's a kind of insect called the stick insect. Man, this thing looks just like a twig! It's long and skinny, and it has the samecolor as the branches in its habitat. When a bird, which is a predator, is flying around looking for food, it'll have a really tough time seeing the stick insect. Because the stick insect is so well disguised as a twig, it can just sit there and be safe. It's like the insect is wearing a super effective invisibility cloak made of nature.The second way is warning coloration. Some animals have really bright and eye catching colors that are like a big sign saying “Stay away from me, I'm dangerous or nasty!” Take the poison dart frog for instance. Thislittle frog is super colorful. It has bright reds, blues, and yellows all over it. Now, predators in the frog's area learn really quickly that these bright colors mean trouble. They know that if they eat the poison dart frog, they'll get sick or even die because the frog is poisonous. So, the bright colors are like a warning label. It's as if the frog is shouting, “Hey,don't you dare take a bite of me, or you'll be sorry!” This way, the frog can protect itself without having to be all sneaky like the stick insectwith camouflage.。

sets.Image___61___made great progress in the2010s thanks to the development of ImageNet,a data set containing millions of images hand sorted into thousands of categories.More recently,GPT-3,a language model,was trained on ___62___online texts to produce humanlike text in Jan,2021.So it is not surprising to see AI being tightly connected with"big data"in the___63___imagination.But AI is not only about large data sets,and research in"small data"approaches has grown extensively over the past decade.The so-called transfer learning serves as an especially___64___example.Also known as"fine-tuning,"transfer learning is helpful in settings where you have___65___data on the task of interest but abundant data on a related problem.You need to first train a model using a big data set and then retrain slightly using a smaller one related to your___66___problem.A research team working on German-language speech recognition,___67___,showed that they could improve their results by starting with an English-language speech model trained on a larger data set.Then,they used transfer learning to___68___that model for a smaller data set of German-language audio.Small data approaches such as transfer learning are more___69___than more data-intensive methods. They can promote progress in areas where little or no data exist,such as in forecasting natural hazards that occur relatively___70___.In this context,small data approaches will become increasingly important as more organizations look to diversify AI application areas and invest in previously___71___fields.Despite the progress in research,transfer learning has received relatively little___72___.While many machine learning experts are likely familiar with it at this point,the existence of techniques such as transfer learning does not seem to have reached the awareness of the broader space of policymakers in positions of making important decisions about AI funding and___73___.As long as the success of small data technique like transfer learning is___74___,resources can be allocated to support their widespread use.In that case,we can help correct the popular___75___regardingthe role of data in AI and foster innovation in new directions.61.

The classes are suitable for both men and women and several women have obtained their black belt.TUESDAY AND THURSDAY6.00—8.00p.m.WEAVER HOUSE GYMFIRST LESSON FREEHardly any of us have experienced real violence,but,over the last few years,attacks on innocent people have increased.Each of us has some ability to defend ourselves,and by learning a form of self-defence,we are not only increasing that ability,but also doing something to build our own sense of respect.Karate will show you a lot of simple and effective techniques to protect yourself,giving you increased self-confidence.Far too many people think martial arts(武术)are about violence.Martial arts training is based on a lot of respect,self-discipline,self-control and non-violence.We learn basic etiquette,courtesy and tolerance. Good manners and consideration for others are expected at all times.Karate is the practice of blocking and striking techniques for the purpose of self-defence,health and self-development.Karate exercises the entire body.Techniques are practised on both sides of the body. Therefore,muscle imbalances do not occur and the strength,coordination,flexibility and agility of both sides of the body are improved.Regular training in Karate improves the body’s physical endurance and flexibility.It also helps concentration and produces the mental calm and assurance that come from knowing we can defend ourselves.Karate has many benefits but they do not come easily or overnight.Training requires ongoing commitment and hard work.Some of you will give up,but a few of you will get your black belt.80.What can be learned about University Shotokan Karate Club?A.More men than women have been its members.B.It tests members to see what level they are at.C.Members don’t need to pay for the lessons.D.It offers4hours of lessons every week.81.According to the passage,which of the following statements about Karate is true?A.It focuses as much on self-defence as on attack.B.It makes people healthy physically instead of mentally.C.It cultivates people’s respect for themselves as well as for others.D.It involves people’s arm muscles more than body muscles.82.The passage is mainly intended to_______.rm readers of benefits of KarateB.correct people’s misunderstanding of KarateC.encourage people to get their black beltD.attract readers to join the club(C)Of all the changes that have taken place in English-language newspapers during the past quarter-century,perhaps the most far-reaching one has been the inevitable decline in the scope and seriousness of their arts coverage.It is difficult to the point of impossibility for the average reader under the age of forty to imagine a time when high-quality arts criticism could be found in most big-city newspapers.Yet a considerable number of the most significant collections of criticism published in the20th century consisted in large part of newspaper reviews.To read such books today is to marvel at the fact that their learned contents were once considered suitable for publication in general-circulation dailies.We are even farther removed from the unfocused newspaper reviews published in England between the turn of the20th century and the eve of World War II,at a time when newsprint was dirt-cheap and stylish arts criticism was considered an ornament（装饰）to the publications in which it appeared.In those far-off days,it was taken for granted that the critics of major papers would write in detail and at length about the events they covered.Theirs was a serious business,and even those reviewers who wore their learning lightly,like George Bernard Shaw and Ernest Newman,could be trusted to know what they were about.These men believed in journalism as a calling,and were proud to be published in the daily press."So few authors have brains enough or literary gift enough to keep their own end up in journalism,"Newman wrote,"that I am tempted to define'journalism'as'a term of contempt applied by writers who are not read to writers who are'."Unfortunately,these critics are virtually forgotten.Neville Cardus,who wrote for the Manchester Guardian from1917until shortly before his death in1975,is now known solely as a writer of essays on the game of cricket.During his lifetime,though,he was also one of England's foremost classical-music critics, a stylist so widely admired that his Autobiography(1947)became a best-seller.He was knighted in1967, the first music critic to be so honored.Yet only one of his books is now in print,and his vast body of writings on music is unknown save to specialists.Is there any chance that Cardus's criticism will enjoy a revival?The prospect seems remote. Journalistic tastes had changed long before his death,and postmodern readers have little use for the richly upholstered Vicwardian prose in which he specialized.Moreover,the amateur tradition in music criticism has been in headlong retreat.83.Which of the following statements is TRUE according to the first two paragraphs?A.English-language newspapers with more arts coverage sell well.B.Young readers nowadays enjoy reading high-quality arts criticism.C.The criticism published in the20th century lacked learned contents.D.There were more arts reviews in English-language newspapers in the past.84.Based on the third paragraph,which of the following statements is TRUE?A.The newsprint was too cheap to make profits.B.Not all writers were capable of journalistic writing.C.Arts criticism was removed from the print newspapers.D.Writers are likely to be tempted into journalism.85.Why was Cardus’s criticism no longer popular?A.Because he mainly wrote essays on the game of cricket.B.Because people cast doubt on his reputation as a knight.C.Because his music criticism failed to appeal to readers nowadays.D.Because his works were quite amateur rather than professional.86.Which of the following is the best title for this passage?A.The Distinguished Critics in Memory.B.The Lost Horizon in Newspapers.C.The Shortage of Literary Geniuses.D.The Newspapers of the Good Old Days.Section CA.Those who learn to forgive deserve respect from others.B.To forgive is something that most people have difficulty with.C.The deeper your pain,the longer it usually takes to completely forgive.D.Forgiveness brings freedom,while hate is neither sweet nor satisfying.E.Forgiveness is necessary because it releases you from the burden of bitterness and hate.F.Psychologically,forgiveness is defined as a decision to release hate toward a person who has harmed you.Are things not working out in your life,despite your doing all the“right”things?Is it possible that you are holding“unforgiveness”in your heart?It is worth thinking about.What do you do when somebody hurts you?Do you want to hurt that person back,or do you hold it against them for the rest of your life?If you answered“yes”to these questions,you are like most people.87People don’t forgive readily,because it is easier to hate than to forgive.Some people think to forgive is a sign of weakness,but actually to forgive takes courage and effort.Forgiveness is a gift from a generous heart.It is not a reward for good behavior.It is not based on whether the person deserves it or whether the person has asked for it.Besides,forgiveness is an act and a long-term process.88It is an act because it is not just the words you say,but also your actions which show if you’ve truly forgiven someone.89It takes a lot of energy to hate and to keep that hate in place.Hate puts unwanted stress on your body.It is a well-known fact,proven by numerous studies,that bitterness can actually make you sick.The moment those affected people forgive and let go of their hate,they will start to get well.90I have personal experience of this.I used to be very cynical（愤世嫉俗的）about life and didn’t forgive easily.At the time,I also struggled in every area of my life.Things just didn’t seem to work out for me.It is as if everything that could go wrong,always went wrong.That was until somebody told me to take a look at my attitude.And when I forgave those who wronged me and changed my attitude, everything else changed.It didn’t happen overnight.It took a while,but I could see and feel the difference.。

In the lecture, the narrator mainly casting doubt on the points claimed in the passage that Tyrannosaurus rex still maintain of the actual tissues of the animal by using several reasons.
Firstly, the professor says that a soft, flexible component in the channel found in the leg bone might not be blood vessels. Namely, it might be something else, narrator holds the opinion that it could be some bacteriers in to hollows and left some soften residual colonies. However in the reading it is stated that channels were blood vessels located. Therefore, this point contradicts the argument made in the passage.
Furthermore, the lecture points out that the exhibit of spheres that might be diffuse origin of reddish minerals. Because some primitive animals do not have red cells. In contrast, the reading claims that spheres could contain blood cells. Thus, the point argued in the reading might not correct.
Lastly, the speaker also thinks that collagen could not existed in leg bone. Specifically because due to the recent research that it is unlikely collagen could live long for such great years. So, the collagen found in the bone could be skin of researchers.
This questions the point that collagen discovered in leg bone is belong to dinosaurs demonstrated in the reading passage.。
