认知觉醒第八章阅读读后感英文回答:Chapter 8 of "Cognitive Awakening" unveils the profound revelations that have shaped our understanding of consciousness and its intricate interplay with our biology and environment. The groundbreaking investigations of researchers like Francis Crick, Christof Koch, and Bernard Baars have illuminated the dynamic nature of conscious experience, challenging traditional notions and sparking a paradigm shift in our quest to unravel the mysteries of the mind.One of the most significant revelations in this chapter is the discovery of the role of the thalamus, a small but critical brain structure, in generating consciousness. Crick and Koch's groundbreaking research demonstrated that the thalamus acts as a "thalamocortical loop," relaying sensory information back and forth between the cortex and the rest of the brain, creating a continuous stream ofneural activity that forms the foundation of conscious experience.Another pivotal concept introduced in this chapter is the Global Neuronal Workspace (GNW) theory, proposed by Bernard Baars. According to this theory, consciousness emerges when information becomes accessible to a globally distributed network of neurons, creating a "workspace" where thoughts, feelings, and perceptions can be integrated and shared among different brain regions. The GNW acts as a central hub, orchestrating the communication and coordination necessary for conscious awareness.Furthermore, the chapter underscores the influence of environment and experience on shaping consciousness. Research has shown that early sensory experiences, such as linguistic input and social interactions, play a crucial role in the development of consciousness in infants and young children. These experiences wire the brain's neural circuitry, establishing the foundation for future cognitive abilities and shaping the subjective nature of our conscious experience.Moreover, the chapter explores the relationship between consciousness and the sense of self. Neuroscientists like Antonio Damasio and Patricia Churchland have argued that consciousness is intricately linked to our ability to create a narrative of ourselves, a coherent and unified story that integrates our past experiences, present perceptions, and future aspirations. This narrative, shaped by both biological and environmental factors, forms the core of our sense of identity and provides a lens through which we interpret the world.中文回答:《认知觉醒》的第八章揭示了深刻的见解,塑造了我们对意识及其与我们的生物学和环境的复杂相互作用的理解。

海底两万里第二部分第8章批注英文回答:Chapter 8 of the second part of "Twenty Thousand Leagues Under the Sea" is an exciting chapter where the Nautilus encounters a giant squid. Captain Nemo and his crew engage in a fierce battle with the squid, showcasing their bravery and skill. The vivid description of the fight between the Nautilus and the squid creates a thrilling atmosphere for the readers.In this chapter, I particularly enjoyed the way Jules Verne portrays the character of Captain Nemo. He is depicted as a fearless and determined leader, guiding his crew through the dangerous encounter with the squid. Captain Nemo's calm and composed demeanor in the face of danger is truly admirable. For example, when the squid attacks the Nautilus, Captain Nemo remains focused and orders his crew to defend the ship. His strategic thinking and quick decision-making skills are evident in thisintense situation.Furthermore, this chapter also highlights the advanced technology and capabilities of the Nautilus. Thesubmarine's ability to maneuver swiftly and effectively in the battle against the squid is impressive. It demonstrates the ingenuity and engineering prowess of Captain Nemo and his team. The Nautilus becomes a symbol of human innovation and exploration in the vast depths of the ocean.The encounter with the giant squid in Chapter 8 serves as a turning point in the story. It not only showcases the bravery and skills of Captain Nemo and his crew but also adds an element of suspense and adventure to the narrative. The readers are left on the edge of their seats, eager to know what other challenges and discoveries await the characters in their underwater journey.中文回答:《海底两万里》第二部分第8章是一章令人激动的章节,纳特勒斯号遭遇到了一只巨型乌贼。

5. Scope of Pragmatics
Pragmatics may be defined as the study of meaning. The word meaning may have many different meanings. In semantics, meaning depends more on who the speaker of the sentence is, who the hearer is, when and where it is used. Meaning depends more on the context.
8.2 Speech Act Theory
This theory originated with the Oxford philosopher John Langshaw Austin. In 1955, when he went to America to deliver the William James lectures, he revised the notes and changed the title from Words and Deeds to How to Do Things with Words, which was published posthumously in 1962.
8.1 Pragmatics
Or rather, you do know the speaker’s intention, but you want to use “What do you mean?” as a denial of what he has asserted. This kind of meaning is sometimes referred to as SPEAKER’S MEANING, UTTERANCE MEANING, or CONTEXTUAL MEANING. The discipline, which concentrates on this kind of meaning, is called PRAGMATICS.

2. Romanticism:
In a historical sense, Romanticism was a movement in philosophy, political theory, and the arts that developed in France and Germany in the latter half of the eighteenth century and flourished in England through to the first three decades in the nineteenth century. The most prominent historical event associated with Romanticism was the French Revolution (1789-1799), which for many presaged the end of aristocratic rule and hereditary social divisions in Europe.

In this chapter, we learn about how to choose the right running shoes for racing and how to improve our speed on the track.First off, the chapter talks about what features to look for in a racing shoe. It's important to find a lightweight shoe that provides good support and cushioning. Racing shoes are designed to be sleek and fast, with minimal cushioning to reduce weight and maximize speed.Next, we learn about the importance of proper form and technique when it comes to running fast. It's not just about how fast you can move your legs, but also about how efficiently youcan move them. Proper arm swing, stride length, and foot strike are all important factors in maximizing your speed.The chapter also discusses the role of training in improving speed.

It was super interesting and I learned a lot of cool stuff!First, we talked about cushioning in running shoes. It's like having a comfy bed for your feet while you run. Some shoes have lots of cushioning, which is great for long distances or if you have a history of foot pain. Others have less cushioning, which is better for speed and agility.Next, we learned about stability shoes. These are like the superheroes of running shoes because they help protect your feet and ankles from rolling inwards or outwards. They're perfect for people with flat feet or those who overpronate or supinate when they run.Then, we talked about motion control shoes. These are like the bodyguards of the running shoe world because they provide extra support for people who have severe overpronation.

In this chapter, we learned all about how to choose the perfect pair of running shoes.First, the book talked about the different types of running shoes - neutral, stability, and motion control. Neutral shoes are for runners with a normal arch, stability shoes are for runners with a low arch, and motion control shoes are for runners with flat feet. It's important to know your foot type so you can pick the right shoes for you!Next, the book discussed the importance of getting the right fit. Your running shoes should be snug, but not too tight. They should also have enough room in the toe box so your toes canmove freely. It's a good idea to try on a few different pairs before making a decision.The chapter also talked about the different features to look for in running shoes, like cushioning, support, and breathability. Cushioning helps to absorb impact, support helps to prevent injury, and breathability keeps your feet cool and dry. All of these things are important for a comfortable and safe run.In conclusion, Chapter 8 of "The Ultimate Running Shoes" taught us the importance of choosing the right pair of shoes for our feet. By understanding our foot type, getting the right fit, and looking for the right features, we can find the perfect running shoes for us.

It's super important to have the right shoes so you can run faster, jump higher, and feel super cool while doing it!First off, you need to think about what type of running you'll be doing. If you're a speed demon and love sprinting, you'll want to go for lightweight shoes with lots of cushioning. These will help you go fast and be comfy at the same time.If you're more of a long distance runner, you'll want shoes with good support and stability. These will help keep your feet happy and healthy as you rack up the miles.There are also shoes for trail running, which have extra grip and protection to handle tough terrain. And don't forget about track spikes for running on the track – they have sharp points on the bottom to help you go even faster!When you're trying on shoes, make sure they fit snugly but not too tight. You want a little wiggle room for your toes, but you also don't want your feet sliding around inside the shoes. And always try them on with the socks you'll be wearing when you run.Remember, the right shoes can make all the difference in your running game. So take your time, try on lots of options, and find the perfect pair that will help you crush your running goals. Happy running, my friends!篇7Chapter 8 of the Ultimate Running Shoes is super cool! In this chapter, we learn all about the advanced technology and cool features of the latest running shoes.First off, we got to know about the innovative cushioning system in the shoes. It's like running on clouds! The special foam material absorbs the impact of each step, making our feet feel super comfy and preventing any injuries.Next, we learned about the unique design of the outsole. It has special grooves and patterns that provide excellent traction on all types of surfaces. So no matter if we're running on the track, road, or trail, our shoes will keep us steady and secure.And let's not forget about the awesome breathable mesh upper! It helps to keep our feet cool and dry, even during intense workouts.

Let's dive into the main points of this chapter.First off, the chapter talks about running shoes forlong-distance running. When you're running a marathon or a long trail race, you need shoes that can provide cushioning and support for miles and miles. Look for shoes with extra padding in the midsole and heel to absorb shock and reduce fatigue. They should also have a breathable upper to keep your feet cool and dry.Next, the chapter covers shoes for sprinting. If you're a speed demon and love sprinting short distances, you need lightweight shoes with a snug fit. Look for shoes with a low heel drop and a stiff sole to help you explode off the starting line. These shoes should also have traction for grip on the track or road.Another important point in this chapter is choosing the right shoes for trail running. Trail running shoes are designed to handle rugged terrain, rocks, and mud. They have aggressive tread patterns for traction and protection for your feet fromsharp objects. Look for shoes with a durable outsole and a protective toe cap for rocky trails.Lastly, the chapter discusses cross-training shoes for other sports and activities.

They should have a stable base for lifting weights, cushioning for running, and flexibility for agility drills.

The people of Atlantis were known for their intelligence and creativity. They had made many scientific discoveries and built incredible structures.One day, a young boy named Tom was exploring near a river when he found an ancient map. The map showed the location of Atlantis, a city that had been lost for centuries. Tom was fascinated by the idea of discovering an ancient city, so he decided to embark on a journey to find Atlantis.Tom gathered a team of explorers and set off on an exciting adventure. They sailed across the ocean, facing many challenges along the way. Finally, they arrived at the coordinates indicated on the map.To their surprise, they found a hidden entrance to a vast underground city. The city was filled with beautiful buildings and advanced technology. The explorers were amazed by what they saw.However, thei r joy didn’t last long. As they explored the city, they discovered that it was abandoned. There were no signs oflife anywhere. It seemed that Atlantis had been deserted for centuries.Tom and his team continued to explore the city, hoping to find some clues about what had happened. They found ancient writings on the walls, but they could not decipher the language.After days of searching, they stumbled upon a room with a strange machine. They realized that it was a time machine. With excitement, they decided to activate it and see if they could travel back in time to the days when Atlantis was flourishing.As they stepped into the time machine, they felt a strange energy enveloping them. Suddenly, they found themselves transported back in time.

Five二Lu Xun is one of the greatest Chinese writers of the 20th century. Besides his famous stories, he also wrote many influential articles about the living conditions of Chinese people.Born in 1881 to a wealthy family, Lu Xun had a happy childhood. In 1893, however, his grandfather, a senior government official, was put into prison for taking money. At the same time, his father became seriously ill. From that time on, his family was no longer accepted by their relatives and friends. These early experiences greatly influenced his writing.By the time Lu Xun arrived in Nanjing to study at university in 1899, he already believed that Chinese society had to change and become modern. In 1902 he went to study in Japan. There he began writing articles for several Chinese student magazines. He showed a gift for writing and translating and he even wrote several books, although none was popular. He returned to China in 1909 because he was in need of money.After working for several years as a teacher in Beijing, Lu Xun again returned to writing. In 1918, he wrote his famous short story Diary of a Madman. It was the first Chinese novel published using the everyday language that people spoke, which helped make it a great success. This, together with his novel The True Story of Ah Q(1921), made Lu Xun a leading Chinese writer.Although successful, Lu Xun still worried greatly about China’s future. In 1927, he moved to Shanghai and gave up writing stories in order to devote himself to what he called “pen warfare”. He only wrote articles which called on the people to fight against the government. For this, the government stopped him from publishing any more books. He was forced to write his articles using false names.Since his death in 1936, Lu Xun’s importance and influence have grown. Today, many of his writings are included in school textbooks and his works are read by millions of people around the world.( )1.

Vocabulary & Reading in-depth1.Vocabulary四级高频词记忆2.Reading in-depth四级阅读之仔细阅读(3)--------【真题演练】01教师讲解【2015.12第一套】Passage OneWhen it's five o'clock, people leave their office. The length of the workday, for many workers, is defined by time. They leave when the clock tells them they're done.These days, the time is everywhere: not just on clocks or watches, but on cell-phones and computers. That may be a bad thing, particularly at work. New research shows that clock-based work schedules hinder morale (士气) and creativity.Clock-timers organize their day by blocks of minutes and hours. For example: a meeting from 9 a.m. to 10 a.m., research from 10 a.m. to noon. etc. On the other hand, task-timers have a list of things they want to accomplish. They work down the list, each task starts when the previous task is completed. It is said that all of us employ a mix of both these types of planning.What, then, are the effects of thinking about time in these different ways? Does one make us more productive? Better at the tasks at hand? Happier? In experiments conducted by Tamar Avnet and Anne-Laure Sellier, they had participants organize different activities-------from project planning, holiday shopping, to yoga-------by time or to-do list to measure how they performed under "clock time" vs “task time." They found clock timers to be more efficient but less happy because they felt little control over their lives. Task timers are happier and more creative, but less productive. They tend to enjoy the moment when something good is happening, and seize opportunities that come up.The researchers argue that task-based organizing tends to be undervalued and under-supported in business culture. Smart companies, they believe, will try to bake more task-based planning into their strategies.This might be a small change to the way we view work and the office, but the researchers argue that it challenges a widespread characteristic of the economy: work organized by clock time. While most people will still probably need, and be, to some extent, clock-timers, task-based timing should be used when performing a job that requires more creativity. It'll make those tasks easier, and the task-doers will be happier.注意:此部分试题请在答题卡2 上作答。

What do the researchers suggest?A) Task-based timing is preferred for doing creative work.B) It is important to keep a balance between work and life.C) Performing creative jobs tends to make workers happier.D) A scientific standard should be adopted in job evaluation.Passage TwoMartha Stewart was charged, tried and convicted of a crime in 2004. As she neared the end of her prison sentence, a well-known col umnist wrote that she was “paying her dues," and that “there is simply no reason for anyone to attempt to deny her right to start anew."Surely, the American ideal of second chances should not be reserved only for the rich and powerful. Unfortunately, many federal and state laws impose post-conviction restrictions on a shockingly large number of Americans, who are prevented from ever fully paying their debt to society.At least 65 million people in the United States have a criminal record. This can result in severe penalties that continue long after punishment is completed.Many of these penalties are imposed regardless of the seriousness of the offense or the person's individual circumstances Laws can restrict or ban voting, access to public housing, and professional and business licensing. They can affect a person's ability to get a job and qualification for benefits.In all, more than 45,000 laws and rules serve to exclude vast numbers of people from fully participating in American life.Some laws make sense. No one advocates letting someone convicted of pedophilia (恋童癖) work ina school. But too often collateral(附随的) consequences bear no relation to public safety. Should a woman who possessed a small amount of drugs years ago be permanently unable to be licensed as a nurse?These laws are also counterproductive, since they make it harder for people with criminal records to find housing or land a job, two key factors that reduce backsliding.A recent report makes several recommendations, including the abolition of most post-conviction penalties, except for those specifically needed to protect public safety. Where the penalties are not a must, they should be imposed only if the facts of a case support it.The point is not to excuse or forget the crime. Rather, it is to recognize that in America's vast criminal justice system, second chances are crucial. It is in no one's interest to keep a large segment of the population on the margins of society.注意:此部分试题请在答题卡2 上作答。
