雅思写作2024年3月小作文
雅思写作2024年3月小作文英文回答:The combination of AI and human capabilities has indeed revolutionized various aspects of our lives. It is an ongoing process that has the potential to further transform our world in numerous ways.Firstly, AI has the ability to enhance humancapabilities by automating routine tasks, freeing up individuals to focus on more complex and creative endeavors. For instance, in the field of medicine, AI-powereddiagnostic tools can assist doctors in analyzing medical images and identifying potential health issues, allowing them to provide more accurate and timely diagnoses. Thisnot only improves patient outcomes but also allows healthcare professionals to spend more time interactingwith patients and providing personalized care.Secondly, AI can augment human intelligence byproviding access to vast amounts of data and information. Through machine learning algorithms, AI systems can sift through large datasets to identify patterns andcorrelations that are often invisible to the human eye. This enhanced intelligence can be leveraged in fields such as finance, where AI-powered algorithms can analyze market data and make predictions, or in scientific research, where AI can assist in the discovery of new drugs and treatments.Thirdly, AI can lead to the development of new products and services that were previously impossible. For instance, in the field of transportation, self-driving cars are a result of the convergence of AI and robotics. These vehicles have the potential to reduce accidents, improve traffic flow, and provide new mobility options for individuals who are unable to drive themselves. Similarly, in the field of entertainment, AI-powered virtual assistants can generate personalized recommendations for movies, music, and other forms of media, enhancing the user experience.However, it is important to note that the integrationof AI and human capabilities is not without its challenges. One major concern is the potential for job displacement as AI systems become more sophisticated and capable of performing tasks that were previously carried out by humans. It is crucial that governments and businesses invest in retraining and upskilling programs to ensure that workers are equipped with the necessary skills to navigate the changing job market.Moreover, there are ethical considerations that need to be addressed as AI becomes more deeply embedded in our lives. For example, the use of AI-powered surveillance systems raises questions about privacy and civil liberties. It is essential that clear regulations and ethicalguidelines are established to ensure that AI is used responsibly and in a manner that respects human rights and values.In conclusion, the integration of AI and human capabilities is a transformative force that has thepotential to reshape our world in profound ways. By leveraging the unique abilities of both humans and machines,we can create a future that is more efficient, intelligent, and inclusive. However, it is important to approach this integration with careful consideration and ensure that we mitigate potential risks and harness the full benefits of this powerful technology.中文回答:人工智能和人类能力的结合确实彻底改变了我们生活的方方面面。

东南大学学位英语Unit 02 How to Write Style完整课文与答案
Section A Intensive Reading and WritingHow to Write with styleBy Kurt V onnegut[1] Newspaper reporters and technical writers are trained to reveal almost nothing about themselves in their writings. This makes them freaks in the world of writers, since almost all of the other ink-stained wretches in that world reveal a lot about themselves to readers. We call these revelations, accidental and intentional, elements of style.[2] These revelations tell us as readers what sort of person it is with whom we are spending time. Does the writer sound ignorant or informed, stupid or bright, crooked or honest, humorless or playful? And on and on.[3] Why should you examine your writing style with the idea of improving it? Do so as a mark of respect for your readers, whatever you’re writing. If you scribble your thoughts any which way, your readers will surely feel that you care nothing about them. They will mark you down as an egomaniac or a chowderhead -or, worse, they will stop reading you.[4] The most damning revelation you can make about yourself is that you do not know what is interesting and what is not. Don’t you yourself like or dislike writers mainly for what they choose to show you or make you think about? Did you ever admire an emptyheaded writer for his or her mastery of the language ? No.[5] So your own winning style must begin with ideas with ideas in your head.1. Find a subject you care about[6] Find a subject you care about and which you in your heart feel others shouldcare about. It is this genuine caring, and not your games with language , which will be the most compelling and seductive element in your style.[7] I am not urging you to write an novel, by the way – although I would not be sorry if you wrote one, provided you genuinely cared about something. A petition to the mayor about a pothole in front of your house or a love letter to the girl next door will do.2. Do not ramble, though[8] I won’t ramble on about that.3. Keep it simple[9] As for your use of language: Remember that two great masters of language, William Shakespeare and James Joyce, wrote sentences which were almost childlike when their subjects were most profound. “To be or not to be?” asks Shakespeare’s Hamlt. The longest word is three letters long. Joyce, when he was frisky, could put together a sentence as intricate and as glittering as a necklace for Cleopatra, but my favorite sentence in his short story , “Evelin”is this one: “She was tried.”At that point in the story, no other words could break the heart of a reader as those three words do.[10] Simplicity of language is not only reputable, but perhaps even sacred. The Bible opens with a sentence well within the writing skills of a lively fourteen-year-old: “In the beginning God created the neaven and the earth.”4. Have guts to cut[11] It may be that you, too, are capable of making necklaces for Cleopatra, so to speak. But your eloquence should be the servant of the ideas in your head. Your rulemight be this: If a sentence, no matter how excellent, does not illuminate your subject in some new and useful way, scratch it out.5. Sound like yourself[12] The writing style which is most natural for you is bound to echo the speech you heard when a child. English was Conrad’s third language , and much that seems piquant in his use of English was no doubt colored by his first language, which was Polish. And lucky indeed is the writer who has grown up in Ireland, for the English spoken there is so amusing and musical. I myself grew up in Indianapolis, where common speech sounds like a band saw cutting galvanized tin, and employs a vocabulary as unornamental as a monkey wrench.[13] In some of the more remote hollows of Appalachia, children still grow up hearing songs and locutions of Elizabethan times. Yes, and many Americans grow up hearing a language other than English, or an English dialect a majority of Americans cannot understand.[14] All these varieties of speech are beautiful , just as the varieties of butterflies are beautiful, No matter what your first language, you should treasure it all your life, If it happens to not be standard English, and if it shows itself when you write standard English, the result is usually delightful, like a very pretty girl with one eye that is green and one that is blue.[15] I myself find that I trust my own writing most, and others seem to trust it most , too, when I sound most like a person from Indianapolis, which is what I am. What alternatives do I have? The one most vehemently recommended by teachers has no doubt been pressed on you, as well: to write like cultivated Englishmen of acentury or more ago.6. Say what you mean[16] I used to be exasperated by exasperated by such teachers, but am no more, I understand now that all those antique essays and stories with which I was to compare my own work were not magnificent for their datedness or foreignness, but for saying precisely what their authors meant them to say. My teachers wished me to write accurately, always selecting the most effective words, and relating the words to one another unambiguously, rigidly, like parts of a machine. The teachers did not want to turn me into an Englishman after all. They hoped that I would become understandable—and therefore understood. And there went my dream of doing with words what words what Pablo Picasso did with paint or what any number of jazz idols did with music. If I broke all the rules of punctuation, has words mean whatever I wanted them to mean, and strung them together higgledy- piggledy, I would simply not be understood. So you , too, had better avoid Picasso-style writing, if you have something worth saying and wish to be understood.[17] Readers want our pages to look very muck like pages they have seen before. Why? This is because they themselves have a tough job to do, and they need all the help they can get from us.7. Pity the readers[18] They have to identify thousands of little marks on paper, and make sense of them immediately. They have to read, an art so difficult that most people don’t really master it even after having studied it all through grade school and high school–twelve long years.[19] So this discussion must finally acknowledge that out stylistic options as writers are neither numerous nor glamorous, since out readers are bound to be such imperfect artists. Our audience requires us to be sympathetic and patient readers, ever willing to simplify and clarify- whereas we would rater soar high above the crowd, singing like nightingales.[20] That is the bad news. The good news is that we Americans are governed under a unique Constitution, which allows us to write whatever we please without fear of punishment. So the most meaningful aspect of out styles, which is what we choose to write about, is utterly unlimited.8. For really detailed advice[21] For a discussion of literary style in a narrower sense, in a more technical sense, I recommend to your attention The Elements of style, by William Strunk, Jr. and E. B. White. E. B. White is, of course, one of the most admirable literary stylists this county has so far produced. You should realize, too, that no one would care how well or badly Mr. White expressed himself, if he did not have perfectly enchanting things to say.Part I Comprehension of the Text1.

The Standards of an Essay3. Essay Writing and English LearningSection B Extensive Reading and TranslationVariety and Style in Language[1] All of us change out behaviour to fit different situations. We are festive, often noisy at weddings and birthday celebrations, sympathetic at funerals, attentive at lectures, serious and respectful at religious services. Even the clothes we wear on these different occasions may vary. Our table manners are not the same at a picnic as in a restaurant or at a formal dinner party. When we speak with close friends, we are free to interrupt them and we will not be offended if they interrupt us; when we speak to employers, however, we are inclined to hear them out before saying anything ourselves. If we don’t make such adjustments, we are likely to get into trouble, We may fail to accomplish our purpose and we are almost sure to considered ill-mannered or worse. From one point of view, language is behaviour; it is part of the we act. It builds a bridge of communication without which society could not even exist. And like every other kind of behaviour, it must be adjusted to fit different contexts or situations where it is used. When we think of all the adjustments regularly made in any on e language, we speak of language variety. When we think of the adjustments any one person makes in different situations, we use the term style. [2] Among people who are used to a writing system, there is one adjustment everyone makes, They speak one way and write another way. Most speech is in the form of ordinary conversation, where speakers can stop and repeat themselves if they sense that they are being misunderstood. They are constantly monitoring themselves as their message comes across to the listeners. But writers cannot do this. (1) They often monitor what they write, of course, going back over their writing to see that it isclear and unambiguous; but this is before the communication occurs, not while it is happening. Once writers have passed their writing on to someone else, they cannot change it.[3] Speakers can use intonation, stress, and pauses to help make their meaning clear. A simple sentence like “John kept my pencil” may, by a shift in the stress and intonation patterns, single out through contrast whether John rather than someone else kept the pencil, whether John kept rather that just borrowed the pencil, or whether it was a pencil or a pen or something else that he kept.[4] (2) It is true that writers have the special tools of various punctuation marks and sometimes typographical helps like capitals, italic letters, heavy type and the like; but these do not quite take the place of the full resources of the spoken language. The sentence “Cindy only had five dollars” is not likely to be misinterpreted when spoken with light stress and no more than level pitch on “only”, but in writing it could easily be taken to mean something else. To prevent ambiguity, skillful writers could change the word order to “Cindy had only five dollars”if they wanted “only”to modify “five”. They would shift “only” to the beginning 0f the sentence if they wanted it to modify “Cindy”.[5] This simple example shows that good writers do try to avoid ambiguity. (3) As writers, they like a structure that is compact; as speakers, thinking aloud, they produce sentences that are looser, less complex, perhaps even rather jumbled. Notice, for instance, that the first sentence in the first letter to Ann Landers reads, “You have made plenty of trouble for me and I want you to know it.” Like most letters to Ann Landers, this is really talk written down. The sentence contains two ideas and treatsthem as equals. If one is really dependent upon the other, a good writer would have written “I want you to know that you have made plenty of trouble for me.”This is not to deny the effectiveness of the original sentence in this very informal letter. [6] Speech makes more use of contracted forms. “He is” (she is) and “he has” (she has ) become “he’s”(she’s); “cannot” becomes “can’t”; “they are ” become “they’re”; “it is”becomes “’tis”or “it’s”; and with a more noticeable change, “will not”becomes “won’t”. So in the conversational letters to Ann Landers, contractions abound, but in the carefully prepared manuscript speeches of the Reverend Martin Luther King and President Kennedy, there are no contracted forms.[7] Besides the difference between speech and writing there is a difference between formality and informality. A formal message is organized and well-rounded; it usually deals with a serious and important topic. Most formal language is intended to be read. Since there is no opportunity to challenge or question the writer when it is being read, the message has to be self-contained and logically ordered.[8] At the opposite pole is the language of casual and familiar speech among friends and relatives, between people who have some kind of fellow feeling for one another. The speaker or writer is simply being him-or herself. This person knows that the others involved – rarely more than five-see and accept the speaker for what he or she is. (4) The speaker also assumes that the others know him or her well enough to make unnecessary any background information for everything that is used. The writer who signed herself “Weepers Finders”assumed that whoever read the letter would recognize the saying, “Finders keepers, losers weepers.”In contrast to the formal style, this style may be called the casual style.[9] There is also a recognizable midpoint between the formal and the casual. There are situations less rigid than the ceremonial address or the formal written message but also more structured than intimate conversation. These permit some response; there is a certain amount of give and take. Yet each speaker will feel the need to be quite clear, sometimes to explain background for the other person’s benefit or in order to prevent misunderstanding or embarrassment. This middle style is known as the consultative style. It should be noted that the consultative style can allow contractions, but rarely would use slang or the incomplete expressions of the casual style.[10] It should not be thought that speech is always informal and writing always formal. (5) The casual style is spoken more often than it is written, but it is found also in letters between friends or family members, possibly in diaries and journals, and sometimes in newspaper columns. Formal English is typically written but may also be spoken after having first been written down. Much consultative speech is spoken, but a fair amount of writing also has the same need for full explanation even if it is otherwise quite informal.[11] Of course, none of there styles or modes of communication is better than any other. The spoken word and the printed page are simply two different ways to communicate. Some people have thought that formal English is “the best”of the stylistic variants, but it is not. Of course, President Kennedy could not have substituted the quite casual “Nobody’s here today to whoop it up for the Democrats”for “We observe today not a victory of party”; but if he had ever used the formal public speaking style at a dinner table, he would have bored everyone there. Intelligent adjustment to the situation is the real key to the effective use of language.[12] In some respects the English language raises certain problems. In conversation some languages allow an easy distinction between the formal and the informal through their dual system of pronouns. In French, for example, intimacy on the one hand or social distance on the other are overtly marked by a choice between “tu” and “vous”. English lacks such a system, but it does have a complex code of choices of title, title and surname, surname alone, given name alone and nickname, as “Doctor”, “Doctor Stevens”, “Stevens ” , “Charles”, “Charley”, and “Chuck”.[13] Another problem arises because of the two-layered nature of the English vocabulary. One layer consists of short, familiar words largely of native English origin ( house, fire, red, green , make, talk); the other of much longer words, chiefly taken from Latin and French ( residence, domicile, conflagration, scarlet, verdant, manufacture, conversation). But it is an oversimplification to equate the popular words with the casual style and the learned words with the formal style. We must admit that many Americans, especially in bureaucratic contests, are fond of big, windy words-words that are often awkward and sometimes inexact.[14] Although adjustment is the key to good use of the various styles, it poses problems for the student coming to English from another language, It is hard enough to become proficient in just one of the styles without having to switch from one style to another. The causal style, in particular, is not easily acquired by the nonnative speaker. Happily, this problem is not too serious. Native speakers of English are much readier to accept the features of the consultative style in a causal situation than to accept casual features in a noncasual situation. Indeed, many Americans are likely to credit a consultative speaker with greater correctness in using English than theyhave themselves. But even if only this one style is acquired, it is important for learners to recognize the other styles when they meet them in speech or writing and to have some sense of the situations that call for their use.Part A Translate English into ChineseI.Translate the underlined sentences in the above text into Chinese.II.Translate the first and the last paragraph in the above text into Chinese.Part B Translate Chinese into EnglishI.

On the Delay of Geographical Caching Methods in Two-Tiered Heterogeneous NetworksAbstractWe consider a hierarchical network that consists of mobile users, a two-tiered cellular network (namely small cellsand macro cells) and central routers, each of which follows a Poisson point process (PPP). In this scenario, small cells with limited-capacity backhaul are able to cache content under a given set of randomized caching policies and storage constraints. Moreover, we consider three different content popularity models, namely fixed content popularity, distance-dependent and load-dependent,in order to model the spatio-temporal behavior of users’ content request patterns. We derive expressions for the average delay of users assuming perfect knowledge of content popularity distributions and randomized caching policies. Although the trend of the average delay for all three content popularity models is essentially identical, our results show that the overall performance of cached-enabled heterogeneous networks can be substantially improved, especially under the load dependentcontent popularity model.Besides, Because of the limitation of research conditions, the total network delay, network cost and optimization of network parameters are not analyzed.Keywords: edge caching, Poisson point process, stochastic geometry, mobile wireless networks, 5GIntroductionIt is known that content caching in 5G heterogeneous wireless networks improves the system performance, and is of high importance in limited-backhaul scenarios. Most existing literature focuses on the characterization of key performance metrics neglecting the backhaul limitations and the spatio-temporal content popularity profiles. In this work, we analyze the gains of caching in heterogeneous network deployment, and consider the average delay as a performance metric.Firstly we use passion point process (PPP) method to build the model. This heterogeneous network consists of mobile terminals (users), cache-enabled small base stations (SBSs), macro base stations (MBSs)and central routers. In this network setting, a user may experience delays due to downlink transmissions, backhaul and caches.Moreover, in order to capture the spatio-temporal content access patterns of users, we suppose fixed content popularity, distance-dependent and load-dependent content popularities. Assuming that the content popularity distribution is perfectly known at the small base stations, we explore three different caching policies based on content-popularity and randomization. And finally, we draw our conclusion.MethodologyFirst, our Research objective is to get the average delay in a cache-enabled two-tiered cellular network modeled by stochastic geometry, the figure one is an illustration of the considered system model, the methodology part including the following parts.The first is the topology, the central routers, MBSs, SBSs, USERs are modeled by the independent PPP models, the second is the signal model, for the tractability for the problem, we assume that the typical user experience the rayleigh fading and the standard power law path loss, also we assume that the network is interference-limited, that is to say the interference power dominates over the noise power.Then it is the caching model, when a user has a content request, we assume that the request is drawn from a continuous zipf distribution, in the function, there is a content popularity parameter, based on this parameter, we have three caching models, Fixed means that the content popularity is identical for all users, all SBSs observe the same distribution, Distance-dependent means that each user has a distance-dependent steepness factor ,the factor is related to the average distance between the SBS and its users.Based on the caching models, here we consider three caching policies: StdPop means the SBSs cache the most popular content from the catalogue, the Unirand means the contents are cached uniformly at random, the MixPop policy means that part storage cache the most popular contents, the other part cache the content at random.The last part is the delay, our metric in this paper, the delay including the following three parts, When the BSs deliver the contents to their intended mobile users, it incurs the downlink delay, When the content requested are not cached in the BSs, the BSs have to get the content form the central routers through the backhaul, then it causes delay, when the content requested in the caches, the content need to be taken out from the caches, it causes delay.Reporting and Discussing ResultsIn this section, we numerically validate our approximations derived in the previous section. The impact of critical system parameters are discussed as follows.Fig. (a) Impact of MBS density. (b) Impact of small cell density.(c) Impact of target SIR. (d) Impact of storage size.Impact of MBS density λmc:The change of average delay with respect to the MBSdensity is given in Fig. a. Therein, as the number of MBSs increases, we observe an increment in average delay at millisecond level. This is mainly due to the backhaul as the delay in backhaul is proportional to the distance and average number of connected MBSs. On the other hand, the average delay in SBSs remains static in this setup. However, we note that the average delay experienced by a typical small cell user is reduced by adding caching capabilities at the base stations.Impact of small cell density λsc: The change of the average delay with respect to the small cell density is depicted in Fig. b. Similarly to the previous figure for MBS density, we see that the average delay increases for all kind of small cell users. However, in this numerical setup, the rateof increment in delay with no-caching capabilities at the SBSs is higher than the delay experienced by the typical users with cache- enabled SBSs. Compared to the fixed and load-dependent content popularities, the typical user under load-dependent content popularity experiences less delay when the number of SBSs increases.Impact of target SIRγ: In our setup, yet another important design parameter is the target SIR. In this regard, the average delay variation with respect to the target SIR is illustrated in Fig. 2c. As observed in the figure, the average delay increases by imposing higher target SIR values. This change is only visible in low values of target SIR, whereas the variation of delay in higher values of target SIR is negligible. This might stem from the fact that the downlink delay is not a dominating factor in our scenario compared to the backhaul delay. A typical user connected to the small cell with no caching capabilities experiences the highest delay, whereas the minimum delay is achieved by using MixPop policy under load-dependent content popularity. The delay of a typical MU remains between a SU with no-caching and caching capabilities at the base stations.Impact of storage size S: Yet another crucial design parameter in our setup is the storage size. The impact of storage size on the average delay is shown in Fig. 2d. Indeed, as observed from the figure, dramatical decrease in delay is observed by increasing the storage size of small base stations. Similarly to previous observations, the most sensitive content popularity for the average delay is the load-dependent content popularity.ConclusionIn this work, we have characterized the average delay of macro cell users and small cell users under backhaul constraints and caching capabilities at the small base stations. We consider a multi-tier heterogeneous network in the two-dimensional Euclidean plane and a typical mobile user, and each base station perfectly observes the content popularities according to three different models: fixed models, distance-dependent models and load-dependent models. After that, some caching policies such as stdPop policies, unirand policies and mixpoppolicies have been considered. Finally the impact of critical system parameters which include macro base stations density, small cell density, target of signal to interference ratio and storage size on the average delay are discussed. Although the trend of the average delay for all three content popularity models is essentially identical, our results show that the overall performance of cached-enabled heterogeneous networks can be substantially improved, especially under the load dependent content popularity model. The main conclusion from this work is that caching at the small base stations allows for balancing the average access delay tothe contents, especially if heterogeneous network densification under limited backhaul is considereReference[1] E.

Unit 1Keys for 1.3.1, 1.3.2Developing an Academic Voice:Most inexperienced writers use only the voices within their experience. When there is narrow experience, there may be the use of inappropriate voice. Writers may resort to their casual voice, which is inappropriate for academic writing. Developing an appropriate voice in academic writing establishes authority and respect for the writer. An academic voice can be developed through understanding categories of voice, recognizing your writing voice, and learning voice changing strategies.Categories of Voice:-Formal voice is an informative voice used in analysis and critique.-Consultative voice is reserved for opinion, reaction, position, and persuasion papers. -Casual voice allows you to share personal knowledge and experience. This style is not appropriate for an academic paper unless expressly allowed by your professor (as in a personal narrative).Strategies for Changing your Voice:- Eliminate casual fillersEliminate words that are associated with casual style and are generally found in conversation. You can ensure you are using an academic voice by avoiding colloquial speech patterns in your writing.Example: “You know,” “well,” “now”- PersonCheck for the appropriate person for each style of paper. First and second person pronouns are sometimes applicable to the consultative voice, but not the formal. Be sure you are consistent with your usage throughout the paper.- Wordiness and Word ChoiceExpress ideas clearly and concisely by removing extraneous words that only provide confusion. Also, remove ambiguous words such as “very” or “great” and select words that provide specific definition.Keys for 2.1.1Key for 2.2A conjunction connects words, phrases, or clauses and can also indicate the relationship between the elements it connects. In only one single sentence we often find that it contains one or more ideas which may be equal or unequal in importance. When the ideas are equal, they are called coordinate ideas. These sentences may be joined into a compound sentence that shows the relationship between the two ideas. When this is done in such a way that the equality of the ideas is maintained, we call the clauses in the new sentence coordinate clauses.Keys for 3.11.Science magazine2.advertisement3.Hemingway’s short story: cat in the rain4. a research paper5. a newspaperKeys for 3.2Key for 3.3There appear to be two principal reasons for the growing traffic congestion.

12月2日雅思大作文真题:老建筑应该被拆除吗关于老建筑物的价值及其是否该拆除,这是个绝对的老题,唐老师在雅思写作教学和讲座中曾多次以本题为例讲雅思写作的基本思路。
那么城市中的老建筑物是否应该拆除?可能有些同学会用一边倒的思维方式来思考这个题目,认为不应该拆除老建筑物,因为这些建筑物有历史和文化价值,应该保留。
这个思路不错,但接下去怎么写呢?这些同学可能就开始懵圈了,因为实在很难找到保留老建筑物的其他理由了。
其实,如果打开思路,我们就会发现,对某些人来说,城市里的老建筑物是应该拆除的,因为抛开历史文化价值,这些老建筑物的确没有实用价值,它们占据着城市的有限空间,既不能居住,也不能为我们的生活提供任何便利,同时维护不好的话,还可能给居民带来危险。
因此,就本题而言,我们可以开始论述应该拆除老建筑物的理由,然后再论述保留老建筑物的理由(同时回答老建筑物对我们的重要意义),最后得出结论:保留老建筑物也许并不能给我们带来实际的生活好处,但其历史和文化价值是不能忽略的。
01 Every city has old buildings. Now the question is: how to deal with these old buildings? Some people think they should be pulled downandreplaced with new ones, while others believe they should be preserved and protected.每个城市都有老建筑。
现在的问题是:如何处理这些老建筑?有些人认为他们应该被推倒,用新建筑取而代之,而另一些人则认为它们应该得到保留和保护。
首先,老建筑不再适合人们居住,因此,它们应该被摧毁,并让位于新建筑,这样城里的人们(尤其是年轻人)才有更多的居住空间。
其次,旧建筑会给城市居民带来不便。
因为没有穿过旧建筑的直路,人们有时不得不绕过它们走很长的路去上下班,这样就浪费了他们很多时间。

2024年3月9日雅思小作文题
2024年3月9日雅思小作文题英文回答:Introduction:The advantages and disadvantages of commuting to work versus working from home are a topic of ongoing debate. Both commuting and working from home offer unique benefits and drawbacks, making it essential to carefully consider the implications of each option before making a decision.Advantages of Commuting to Work:Social interaction: Commuting to work provides an opportunity to interact with colleagues, engage in casual conversations, and build relationships. This social interaction can foster a sense of community and belonging within the workplace.Separation of work and home life: Commuting acts as aphysical and psychological boundary between the workspace and the home environment. This separation can help maintain a healthier work-life balance and reduce the risk of work-related stress spilling over into personal life.Structured routine: The regular schedule of commuting can provide a sense of structure and discipline to the workday. It establishes clear start and end times, which can help manage time more effectively.Disadvantages of Commuting to Work:Time-consuming: Commuting can be a significant time investment, especially in large cities or congested areas. This time could be better spent on work-related tasks, personal errands, or leisure activities.Stressful: Commuting can often be stressful due to traffic congestion, delays, and unpredictable travel conditions. This stress can negatively impact both physical and mental well-being.Environmental impact: Commuting by car contributes to traffic congestion and air pollution, which can have detrimental effects on the environment.Advantages of Working from Home:Flexibility: Working from home offers greaterflexibility in terms of work hours, location, and workload. This can be particularly beneficial for individuals with family responsibilities or those seeking a more flexible work-life balance.Increased productivity: Studies have shown that employees who work from home can be more productive due to fewer distractions, a more comfortable work environment, and the ability to work at their peak performance times.Cost savings: Working from home can save on commuting expenses, such as gas, public transportation, and parking. Additionally, it reduces the need for work-related wardrobe expenses.Disadvantages of Working from Home:Social isolation: Working from home can lead to social isolation, as individuals may have fewer opportunities to interact with colleagues and build workplace relationships.Lack of structure: The absence of a physical workplace can make it challenging to establish a structured workday. This can lead to procrastination and difficulty maintaining motivation.Technical challenges: Working from home relies on reliable internet and technology, which can be a source of frustration and downtime if not functioning properly.Conclusion:The decision of whether to commute to work or work from home is a personal one that depends on individual circumstances and preferences. Both options offer advantages and disadvantages, and the best choice will vary depending on factors such as work demands, lifestyle, andpersonal values. Carefully weighing the pros and cons of each option will help individuals make an informed decision that aligns with their goals and aspirations.中文回答:通勤上班与在家工作的利弊。

On the Delay of Geographical Caching Methods in Two-Tiered Heterogeneous Networks
Abstract
We consider a hierarchical network that consists of mobile users, a
two-tiered cellular network (namely small cellsand macro cells) and central routers, each of which follows a Poisson point process (PPP). In
this scenario, small cells with limited-capacity backhaul are able to cache content under a given set of randomized caching policies and storage constraints. Moreover, we consider three different content popularity models, namely fixed content popularity, distance-dependent and load-dependent,in order to model the spatio-temporal behavior of users’ content request patterns. We derive expressions for the average delay of users assuming perfect knowledge of content popularity distributions and randomized caching policies. Although the trend of the average delay for
all three content popularity models is essentially identical, our results show that the overall performance of cached-enabled heterogeneous networks can be substantially improved, especially under the load dependentcontent popularity model.
Besides, Because of the limitation of research conditions, the total network delay, network cost and optimization of network parameters are
not analyzed.

Introduction
It is known that content caching in 5G heterogeneous wireless networks improves the system performance, and is of high importance in limited-backhaul scenarios. Most existing literature focuses on the characterization of key performance metrics neglecting the backhaul limitations and the spatio-temporal content popularity profiles. In this work, we analyze the gains of caching in heterogeneous network deployment, and consider the average delay as a performance metric.
Firstly we use passion point process (PPP) method to build the model. This heterogeneous network consists of mobile terminals (users), cache-enabled s mall base stations (SBSs), macro base stations (MBSs)。
