Humans spend approximately one-third of their lives sleeping, which means that by the time you reach 15 years old, you will have slept for about 5 years! However, the question remains: why do we do it? Sleep has long been a puzzle for people, leading scientists to explore its mysteries. They have found that during sleep, our brains and bodies do not simply shut down; instead, complex processes unfold.

What causes sleepiness? It's caused by our biological clock releasing a special chemical signal at the same time daily, signaling it''s time to wind down. The feeling of heaviness comes from the buildup of old nerve messenger chemicals. When the message gets too much, the brain senses that it's time to sleep. During sleep, the body breaks down and clears away these old messengers, preparing for a fresh start.

As you slip into sleep, your heart and breathing slow down, and your brain ignores the most sounds and surroundings around you. Despite appearances, your brain remains active during sleep, performing essential tasks. Throughout the night, you cycle through light, deep, and REM(rapid eye movement) sleep stages every 90 minutes. Early on, slow-wave sleep is the primary stage, aiding in brain cleaning, while towards morning,REM sleep increases, leading to vivid dreams.         During sleep, your body repairs and grows, creating new skin, muscle, and other tissues with released chemicals. It's also a time for hormone(荷尔蒙)production, aiding growth, and boosting the immune(免疫)system to fight infections.

Scientists still have many questions about sleep, such as why some people need more sleep than others and how certain animals can function with less sleep. They aim to find ways to improve sleep quality. However, one thing is clear: getting enough sleep is vital for health and intelligence. Think of sleep as a free magic potion that strengthens you, aids growth, boosts immunity, and enhances intelligence, happiness, and creativity. Simply lie down and rest to enjoy these benefits.

(1) What inference can be drawn from scientists'findings about sleep? A. Sleep serves no purpose. B. Sleep has fundamental processes, C. Sleep involves complex processes. D. Sleep has minimal impact on brain function.
(2) What is the primary function of the body 's "biological clock"? A. Determining the best time for sleep. B. Controlling chemicals within the body. C. Managing eating and digestion patterns. D. Regulating daytime and nighttime activities.
(3) What is the main focus of the third paragraph? birh-yno vist8mxonq A. Describing the different stages and functions of sleep. B. Discussing the benefits of daytime activities for overall health. C. Exploring the effects of inadequate sleep on the body and mind. D. Analyzing the impact of stress on the immune system during sleep.
(4) Which of the following best describes the structure of the passage? A. Narrative of personal sleep experiences. B. Comparison of human and animal sleep patterns. C. Imaginary stories illustrating the advantages of sleep. D. Explanation of sleep importance, with body processes described.

A fallacy is an error in reasoning based on opinion, misunderstanding, or intentional misdirection that makes an argument invalid. Common causation (因果关系) fallacies include those of oversimplification and exaggeration, which occur when actual causes of an event are reduced to the point where connections between causes and effects are blurred or buried. 

Oversimplification is common, which means reducing multiple causes to just one or a few. Well-intentioned writers and speakers can fall into the trap of oversimplification if not careful. 

One motivation for simplification is the basic advice given to writers: Don't get stuck in details. In the process, however, a writer can leave out too many details, even critical information. Another contributing factor to oversimplification is the overuse of an important tool in critical thinking called Oceam's Razor, a principle that states that the simplest explanation that fits the data is the preferable one. The problem is that the simplest explanation might not always be the right-one. 

A writer creating an argument can assume that based on Occam's Razor, the simplest explanation is likely true, but they must not assume that is always the case. They must look at all angles and complexities of an issue before settling on the simplest explanation. 

Here is an example of oversimplification:

School violence has gone up and academic performance has gone down since video games featuring violence were introduced. Therefore, video games with violence should be banned, resulting in school improvement.

This argument exhibits oversimplification because it assumes problems in schools (increasing violence, decreasing academic performance can be attributed to a single cause: the time young people spend playing video games that feature violence). Various other factors, including social and economic conditions that may contribute to a child's mental health, are ignored. 

Related to the fallacy of oversimplification is the fallacy of exaggeration-multiplying a couple of causes into many.

(1) What does paragraph 3 mainly focus on? A. The causes of oversimplification. B. The impact of oversimplification. C. The definition of oversimplification. D. The characteristics of oversimplification.
(2) How do writers commit oversimplification when creating an argument based on Occam's-Razor? A. They consider an issue to be complicated. B. They look at an issue from different angles. C. They believe the simplest explanation is likely true. D. They have absolute trust in the simplest explanation.
(3) Which of the following statements is an example of oversimplification? A. The nation's lack of moral standards is caused by multiple factors. B. The latest currency policy takes full blame for the declining economy. C. She was saved because of the seal belt as well as doctors' timely saving. D. The problem of education not just lies in teachers' failure of doing their jobs.
(4) What might the author discuss in the paragraphs that follow? A. Ways to avoid oversimplification. B. More examples of oversimplification. C. Causes and examples of exaggeration. D. The distinction between exaggeration and oversimplification.

Among the constant adjustive education standards and requirements, it's important to ask a question: exactly what do we want in a high school graduate?

Some people think the goal is to enter college and earn a bachelor's degree. Others find that interpretation too narrow, preferring that young people leave school with the skills to move into living-wage jobs. But one thing many people can embrace is that high school graduates are skilled in basic math and English.

A proposed law, House Bill 1308, could ruin that goal. Students must do the following things to get a diploma: earn 24 credits of coursework; complete a High School and Beyond Plan matching those courses; meet one requirement of a series of "graduation pathways". The problem is that these pathways don't work for all kids.

In large part, that's because they guide students toward college standards. Last year, after surveying nearly 1, 000 students, researchers discovered that 18% of students said they were "not good" at math, and 33% said they were poor test-takers. For them, the current pathways are a barrier because of their emphasis on these skills.

The new pathway is instead focused on performance. It would allow kids to create a presentation—say an exhibit or report—demonstrating mastery of two core subjects, but not necessarily math or English. When the bill came up for discussion, over 350 people showed their support, because it's possible that through the performance pathway, a student could create a project emphasizing mastery in "fine arts "and" health and fitness". Rep. Sharon favors the proposal. In a hearing, she spoke of her granddaughter, who wrote and self-published a novel while still in school, to illustrate the kind of project is workable. While Tafona Ervin worries that the lack of emphasis on math and English could lead students to graduate without solid skills.

If the purpose of education is to ensure that young people are prepared to pursue a fulfilling life, finishing school uncertain of one's abilities in math and English weakens education's goal.

(1) Why is the question mentioned in the first paragraph? A. To make an argument. B. To introduce the topic. C. To raise an education problem. D. To clarify a concept.
(2) How many items does House Bill 1308require for high school students to graduate? A. One. B. Two. C. Three. D. Four.
(3) How does the writer make his points persuasive in Para. 4? A. By making comparisons. B. By offering statistics. C. By providing suggestions. D. By doing experiments.
(4) What does the author think of House Bill 1308? A. Workable. B. Effective. C. Awful. D. Reasonable.

Yue-Sai Kan was born in 1946 in Guilin, Guangxi Zhuang autonomous region, and grew up in Hong Kong. In 1968, while majoring in piano at the Hawaii campus of Brigham Young University, Kan entered a beauty contest sponsored by the local Chinese Chamber of Commerce. She won second place, and as a result got to travel around the world. The life-changing experience marked the beginning cf her career in fashion, beauty, communication and cultural exchange.

In 1972, she moved to New York and created the weekly television series Looking East, the first of its kind to introduce Asian cultures and customs to a growing US audience.
