认知觉醒第八章阅读读后感
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。

现代英语语言学理论 CHAPTER 8
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 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.

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.

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。

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。
