Introduction:Ordinal numbers play a crucial role in English writing, providing a sequential order to events, ideas, or objects. From dates and rankings to instructions and procedures, the use of ordinal numbers is essential for clear communication. This essay aims to explore the significance of ordinal numbers in English writing and how they contribute to effective expression. By examining various contexts and examples, we will delve into the diverse applications of ordinal numbers and their impact on conveying information accurately.1. First and foremost, ordinal numbers are frequently used to indicate positions or rankings. Whether it is a sports competition, academic achievements, or a list ofpreferences, ordinal numbers provide a clear hierarchy. For instance, in a race, the first, second, and third positions are represented by "first," "second," and "third" respectively. These ordinal numbers help to categorize participants based on their performance, allowing readersor listeners to comprehend the relative standing of each individual.2. Ordinal numbers are also essential when discussing dates and chronological order. They enable us to expressthe sequence of events, historical occurrences, or even personal experiences. For example, "On the 10th of July, 1776, the United States declared its independence"highlights the specific date and its historical significance. Similarly, when recounting a personal journey, phrases like "On my third day in Paris" or "The second time I visited London" provide a clear sense of temporal progression.3. In addition, ordinal numbers are indispensable when giving instructions or describing procedures. They guide readers or listeners through a step-by-step process,ensuring clarity and coherence. For instance, a recipe might include instructions such as "First, preheat the oven to 180°C. Then, mix the dry ingredients in a bowl. Next, add the wet ingredients and stir well." The use of ordinal numbers helps readers follow the recipe systematically, avoiding confusion and achieving the desired outcome.4. Furthermore, ordinal numbers are often employed in academic and scientific contexts to denote the order of elements in a series or a list. This is particularly useful when presenting data, statistics, or findings. For example, a research paper might state, "In the first experiment, participants were asked to complete a questionnaire. In the second experiment, a different group was exposed to avisual stimulus." By utilizing ordinal numbers, the writer ensures that the reader can differentiate between different stages or components of the study.5. Ordinal numbers are also vital in expressing age or describing the order of siblings in a family. They help us understand birth order and establish relationships between individuals. For instance, "My younger brother is the thirdchild in our family" or "She is my eldest cousin" provide essential information about family dynamics and the hierarchy among siblings or relatives.6. Moreover, ordinal numbers are frequently used inlegal and official documents, such as contracts, agreements, and legislation. They ensure precision and accuracy when referring to specific sections, articles, or clauses. For example, "In Article 5, Section 2, the right to freedom of speech is outlined." The use of ordinal numbers in legal contexts ensures that all parties involved can easilylocate and reference specific provisions, ensuring transparency and clarity.Conclusion:In conclusion, ordinal numbers are indispensable in English writing, providing a clear and concise way to express rankings, positions, dates, instructions, academic information, age, and legal references. Their usage establishes a logical order, enabling effective communication and comprehension. By understanding thesignificance of ordinal numbers and their diverse applications, writers can enhance their ability to convey information accurately and engage readers more effectively.。

The Magic of a Family Secret Family secrets have the power to both bind and divide families, creating a sense of mystery and intrigue that can have a lasting impact on the members involved. The magic of a family secret lies in its ability to shape the dynamicsof a family, influencing relationships and individual identities in ways that may not always be immediately apparent. As a family secret is often passed down from generation to generation, it becomes an integral part of a family's history, influencing the way in which its members perceive themselves and each other. From a historical perspective, family secrets have been a common phenomenon throughout human history, often serving as a means of protecting the reputation and social standing of a family. In some cases, family secrets have been used to conceal scandalous or taboo behavior, such as illegitimate children, extramarital affairs, or criminal activities. By keeping these secrets hidden, families have been ableto maintain a facade of respectability and honor, shielding themselves from potential shame and judgment from the outside world. However, the impact of a family secret is not limited to its historical context. On a personal level, the revelation of a family secret can have profound effects on individual family members, shaping their sense of identity and belonging. For those who are directly involved in the secret, such as the individuals who are the subject of the secret or those who have been entrusted with its safekeeping, the burden of secrecy canbe overwhelming, leading to feelings of guilt, shame, and isolation. On the other hand, for those who are kept in the dark about the secret, the discovery of the truth can be a source of betrayal and disillusionment, causing rifts in family relationships and eroding trust. The magic of a family secret lies in its ability to create a sense of mystery and intrigue, fueling the imagination and sparking curiosity among family members. The unknown nature of a family secret can lead to speculation and rumors, as individuals attempt to piece together the fragments of information that they have been able to gather. This can create a sense of unity among family members, as they come together to uncover the truth and make sense of their shared history. However, the same sense of mystery can also lead to division, as different family members may have conflicting interpretations of the secret, leading to disagreements and disputes that can strain relationships. In somecases, the revelation of a family secret can lead to a sense of liberation and catharsis, as the truth is finally brought to light and the burden of secrecy is lifted. This can create an opportunity for healing and reconciliation within the family, as individuals are able to confront the past and move forward with a greater sense of understanding and acceptance. However, the process of revealing a family secret can also be fraught with challenges, as individuals may struggle to come to terms with the truth and its implications for their own lives. This can lead to feelings of anger, resentment, and betrayal, as individuals grapple with the realization that they have been kept in the dark about a significant aspect of their family's history. Ultimately, the magic of a family secret lies in its ability to shape the narrative of a family's history, influencing the way in which its members perceive themselves and each other. Whether it serves as a means of protection or a source of division, a family secret has the power to leave a lasting impact on the dynamics of a family, shaping the relationships and individual identities of its members in ways that may not always be immediately apparent. As families continue to grapple with the legacy of their secrets, it is important to recognize the profound influence that these hidden truths can have, and to strive towards open communication and understanding in order to foster healing and unity within the family unit.。
As a high school student with a keen interest in business and economics, Ive always been fascinated by the dynamics of the corporate world. One aspect that particularly caught my attention is the fluctuationin employee numbers within companies. This essay delves into my observations and thoughts on this matter, drawing from personal experiences, case studies, and a bit of research Ive done.Growing up, I was often around discussions about work as my parents were both employed in large corporations. I remember hearing about layoffs and hiring sprees, which seemed to be part of the natural rhythm of business life. The first time I truly grasped the impact of employee numbers was when my fathers company underwent a significant restructuring. It was a tech firm that had expanded rapidly but faced a downturn in the market. The decision to reduce the workforce by 20% was a tough call, but one that was deemed necessary for the companys survival.I saw the stress this caused in my fathers eyes, and it made me realize the human cost behind such decisions.In school, I took a course in business studies where we discussed various factors that influence the number of employees in a company. One of the most compelling lessons was on the economic cycle and its effect on employment. During periods of economic growth, companies tend to hire more employees to meet increased demand. Conversely, during a recession, companies often downsize to cut costs. A reallife example that stuck with me was the impact of the 2008 financial crisis on the automotive industry. Many car manufacturers had to let go of a significant number of workers as sales plummeted.Another factor we explored was technological advancements and their role in shaping employee numbers. Automation and artificial intelligence have the potential to replace certain jobs, leading to a decrease in the demand for human labor in specific sectors. However, they also create new job opportunities in areas like software development and data analysis. A case in point is the rise of ecommerce giants like Amazon, which have automated many aspects of their operations but also created thousands of jobs in their warehouses and tech hubs.I also learned about the importance of company culture and its influence on employee retention. Companies that foster a positive work environment and offer opportunities for growth and development are more likely to retain their employees. This was evident in a project I did on Google, a company renowned for its innovative culture and employee benefits. Their low turnover rate is often attributed to the supportive and stimulating environment they create for their staff.In addition to these factors, Ive come to understand that the fluctuation in employee numbers can also be a strategic move by companies. For instance, startups often start with a small team and gradually expand as they secure more funding and establish their market presence. On the other hand, established companies might choose to downsize to streamline operations and increase efficiency.What I find most intriguing is the balance companies must strike between meeting their business needs and considering the wellbeing of theiremployees. Its a complex equation that involves financial, ethical, and social considerations. As I look towards my future, I hope to be part of a company that values its workforce and treats its employees with respect and fairness.In conclusion, the changes in employee numbers within a company are influenced by a myriad of factors, from economic conditions and technological advancements to company culture and strategic decisions. As a student, I am keen to continue learning about these dynamics and one day contribute to shaping them in a way that benefits both the business and its people.。

Rather than a memoir (回忆录) , this energetic collection integrates her stories into contexts — literary, political, spiritual, familial.In Sketch, the first and longest piece in the book, Waldman describes what guided her to poetry from an early age — Her intellectual and artistic parents encouraged her “to read widely, to write, think, talk about it, be curious and critical.” Reading Sketch for its wonderful autobiographical details and the successful moments that run through Waldman’s life is a pleasure. In Interview with Poetas, Madrid 2018, another piece from the book’s second section, she wrote, “We need cultural and humanitarian revolution. We need poetry to remind us of the magic we have had that needs attendance and recharge.” Her voice and vision have a collective width.Waldman insists on combining art with nearly every aspect of her life. Bard, Kinetic, at all points, a high-energy construct, and at all points, an energy-discharge, puts readers on the path to recognizing poetry as a mental aid, as an action that reaches across geography, species, and time. As she wrote in the book’s preface, she commands herself to “keep pushing for knowledge, study with a deeper investigation and a deeper action. The action, totally necessary”. These are high aims that Waldman has insisted on, tirelessly, her entire life. Waldman shines. Her heart could be our heart.This new book is best read as a companion of V ow to Poetry (2001), Waldman’s previous collection of interviews and autobiographical essays, which will help readers appreciate this book better.4．What do we know about Bard, Kinetic by Waldman?A．It is a memoir.B．It documents her life and work.C．It is her first collection of poems.D．It is to be issued by Coffee House Press. 5．What’s the purpose of paragraph 3?A．To add relevant background information.B．To help readers gain partial insight into the book.C．To persuade readers to conduct selective reading.D．To introduce Waldman’s writing styles.6．What is implied in the underlined sentence “Her heart could be our heart.” in paragraph 4?A．We should stick to our goals.B．We should learn poems by heart.C．We should seek fame and wealth.D．We should enjoy life to our hearts’ content.7．What’s the text?A．A diary entry.B．A news report.C．A book review.D．An autobiography.Many important decisions boil down to a choice between keeping the supposed safety and risking going out for a chance at getting something even better. Though risk-taking preferences vary between individuals, research with humans shows that we’re all generally less willing to take risks in situations with more ambiguous（模糊的）outcomes. “The finding should also apply to risk-taking in chimps（黑猩猩）, one of our closest evolutionary（进化的）ancestors,” said Haux, from Max Planck Institute for Human Development.To test the evolutionary roots of human risk preference, Haux and his colleagues measured 55 chimps living in reserves for their risky and ambiguous choices in an experimental setting. In each trial, they chose a ball from one of two pots. One pot was always safe because it contained two balls filled with one peanut each. In the risky condition, the second pot also contained two balls, but one was filled with two peanuts and the otherwith nothing. In the ambiguous condition, the balls in the second pot still contained two rewards or nothing, but the contents in the pot was entirely invisible to the chimps.On average, chimps chose the risky pot over the safe pot 55% of the time but chose the ambiguous pot over the safe pot in just 25% of trials. This suggests that chimps, like humans, prefer to avoid situations with ambiguous versus known risks.“Structural similarities in risk preferences of humans and one of our closest living relatives are likely to reflect adaptations to similar dynamics in evolution. While many other factors may influence human risk-taking preferences, the parallels between human and chimp behavior suggest that evolutionary adaptions have helped set a consistent baseline,” Haux said.Future work will compare how the risk-taking preferences of chimps living in reserves may differ from those living in zoos or in the wild, as well as how they compare to those of bonobos, another close evolutionary relative of humans, Haux added.8．Why was the research on risk preference conducted on chimps?A．To test their intelligence level.B．To guide them to make wise decisions.C．To prove the evolutionary consistency.D．To distinguish each individual’s difference.9．Which illustrates the risky condition in the experimental setting?A．B．C．D．10．What does the underlined word “parallels” in paragraph 4 probably mean? A．Conflicts.B．Interactions. C．Misunderstandings.D．Similarities.11．What can be inferred from the last paragraph?A．The range of the subjects will be extended.B．Haux is satisfied with the current research.C．Bonobos are a close evolutionary relative of humans.D．The research topic will be shifted into another field.With lunar exploration rocketing, it poses many challenges. Among them is a fundamental question metrologists (计量学家)worldwide are working to answer: what time is it on the Moon?The Moon doesn’t currently have an independent time. Each lunar mission uses its own timescale to coordinated universal time, or UTC—the standard against which the earth’s clocks are set. The approach works when the Moon hosts a handful of independent missions, but it will be a problem when there are multiple craft working together. Space agencies will also want to track them using satellite navigation, which relies on precise timing signals.The most pressing need for lunar time comes from plans to create a dedicated global navigation satellite system (GNSS) for the Moon. To tackle this problem, representatives of space agencies and academic organizations worldwide met in November 2022 to start drafting recommendations on how to define lunar time.Defining lunar time is not simple. According to the Special Theory of Relativity, clocks tick slower in stronger gravitational fields. The Moon’s gravitational pull is weaker than Earth’s, meaning a lunar clock would run faster than an Earth one.Defining a lunar standard, with which all clocks are compared, will involve installing at least three master clocks that tick at the Moon’s natural pace, and whose output is combined by an algorithm (算法)to generate a more accurate ‘virtual’ timepiece.What happens then depends on which option metrologists choose. They might decide to base lunar time on UTC．The alternative would be to use the synthesized (同步)output of the lunar atomic clocks as the Moon’s own independent, continuous time, and to track its relationship to UTC．That way, even if the connection with Earth is lost, clocks on the Moon will still agree with each other, allowing safe navigation and communications.Setting lunar time is part of a much bigger picture. It will one day work for the more-distant planets that space agencies are ultimately targeting, such as Mars.12．What’s the main idea of paragraph 2?A．The working principle of UTC．B．The achievements of space mission.C．The urgency to develop satellite navigation.D．The problem of current lunar timing method.13．What is the major barrier to defining lunar time?A．Lack of professional guidance.B．The disagreement among metrologists.C．Different gravitational pull on the Moon.D．The complexity of installing master clocks.14．What’s the advantage of defining the Moon’s independent time?A．Keeping the clocks on the Moon corresponding.B．Preventing spacecraft losing connection with the Earth.C．Helping humans land on the more-distant planets.D．Making it easier to synchronize with UTC all the time.15．What’s the best title of the text?A．What Time Is It on the Moon?B．When will Man Settle on the Moon?C．Lunar exploration: A Career Bound to ReviveD．GNSS: A More Precise Lunar Tracking System二、七选五STEM vs. STEAMSTEM is short for Science, Technology, Engineering and Mathematics. The term was coined by Judith Ramaley while a director at National Science Foundation in 2001. Since then, STEM-focused education has been extended to many countries beyond the United States. However, education is a constantly evolving game. ____16____ One of the latest philosophies gaining steam is adding an arts component to the STEM educational focus, thus, creating the STEM vs. STEAM debate.The believers in STEM education want the focus to remain on the core STEM principles. ____17____ Tasks involving product design encourage students to draw and create. Adding arts will take away from the original intention of focusing on the STEM disciplines.____18____ They argue that adding arts to STEM is a way to develop strong STEM students who think creatively. Several studies have shown that engaging students’ arts strength increases their motivation when it comes to STEM activities. ____19____ Furthermore, for kids who might be turned off from STEM subjects due to a dislike of numbers, highlighting the artistic component of lessons can reach out and draw them in.While they seem to be opposed, both sides of this argument may have the right idea.____20____ Consider the growing field of computer animation, where you must have both artistic abilities and strong technology fields. Also, the most basic of all children’s toys, wooden blocks, are an incredible example of STEAM exploration. They bring design, geometry, and engineering concepts to our youngest learners, setting them up for a lifetime of creative thinking.A．The STEAMers disagree.B．Actually, science and arts are inseparable.C．It consistently introduces new theories and practices.D．Their idea is that there are already enough arts in their approach.E．Thus, good teachers are always learning to keep pace with updated knowledge.F．It also improves the probability of success in complicated tasks and challenges. G．They believe adding art makes the STEM courses accessible to more students.三、完形填空One snowy night, a pair of beagles（比格犬）was struggling on a rural highway.
