topic sentences的定义
“Topic sentences”的意思是“主题句”，它是一个段落或文章的中心思想的概括性句子。
主题句通常出现在段落的开头，有时也可能出现在段落的中间或结尾。
主题句的作用是向读者明确段落或文章的主要内容和重点，它可以帮助读者快速理解段落或文章的主旨。
主题句通常简洁明了，能够概括段落或文章的核心观点或主题。
在写作中，使用主题句可以使文章结构更加清晰，逻辑更加连贯。
通过主题句的引导，读者可以更容易地跟上作者的思路，并理解文章的整体框架。
同时，主题句也为段落或文章的其他句子提供了一个框架和指导，确保它们都与主题相关并支持主题的阐述。
以下是一个主题句的示例：
“化石记录显示，恐龙在大约6,600 万年前灭绝，为哺乳动物的崛起铺平了道路。
”
在这个例子中，主题句明确了段落的主要内容，即恐龙的灭绝以及它对哺乳动物崛起的影响。

主题句简介topic sentence
主题句简介topic sentence二、主题句简介2．1 主题句作者的首要任务是让读者知道所写段落要谈的是什么，这就是每段的主题句的作用。
因此主题句应该阐明段落的主要思想，所有支持主题句的细节和描述都与这一主要思想有关。
2．2 主题句的形式主题句通常有以下三种形式：1）肯定句（Affirmative Sentence）Example：The need for wildlife protection is greater now than ever before．2）反诘句（Rhetorical Sentence）Example：How do you think people will solve the problem of wildlife protection？3）不完整句（Fragments）Example：And the workingman？初学者最好使用肯定句作为主题句。
2．3 主题句的位置主题句出现的位置有以下四种情况：1）段首（At the beginning）主题句经常居于段首，以便读者浏览主题句就可掌握文章的概要。
这个位置适用于写提供信息或解释观点的段落。
2）段末（At the end）用推理方法展开段落时，主题句往往位于句末。
3）段中（In the middle）有时为了使段落多样化，主题句也可以居于段中。
4）隐含（Implied）有时候，尤其在写叙述性或描写性段落时，当所有的细节都围绕着一个显而易见的主题时可以不用主题句。

英语写作万能句：主题句
主题句(topic sentence)是表达段落主题的句⼦。
它⽤以概括段落⼤意，要求全段其他⽂字都围绕它展开。
请看下例： My mother has passed along to me certain rules for getting along with others. Don't argue with parents; they will think you don't love them. Don't argue with children; they will think themselves victimized. Don't argue with spouses; they will think you are a tiresome mate. Don't argue with strangers; they will think you are not friendly. My mother's rules, in fact, can be summed up in two words: Don't argue. 主题句中提出的 "certain rules" 指的是什么?展开句中通过四个 "Don't argue --" 逐⼀加以交代。
从结构来看，这是⼀个⽐较典型的段落，它包括了主题句，推展句和结论句(即本段中的末句)。
1.1 主题句的位置 主题句通常放在段落的开端，其特点是开门见⼭地摆出问题，然后加以详细说明。
其作⽤是使⽂章的结构更清晰，更具说服⼒，便于读者迅速地把握主题和想象全段的内容。
主题句可以放在段中起到承上启下的作⽤，或放在段尾起概括全段的作⽤。
但初学者⽐较难于掌握，因⽽在四级考试中，考⽣应尽量采⽤将主题句放在段落开头的写作⼿法。
， 例1: Our life today depends very much on energy. In towns and in villages, on farms and in factories, machines have made life easier than it used to be. The machines use energy, and energy is needed for heating, lighting, communications, carrying goods -- everything. Factories and industrial plants use a great deal of energy to make the things that we use and buy and sell.， 这段⽂字所讲的主要是能源问题。

请注意，文章应为原创，不得抄袭。
例：Social media has drastically changed the way we communicate [社交媒体已经彻底改变了我们的交流方式]随着社交媒体的普及，我们已经越来越依赖于这些平台来与朋友、家人和同事保持联系。
然而，这种交流方式给我们带来了一些好处和挑战。
在本文中，我们将深入探讨这些问题，并提供解决方案。
首先，社交媒体改变了我们的社交方式。
以前，人们主要通过电话、面对面会议或邮件来沟通。
现在，我们可以通过社交媒体平台上的即时信息、视频聊天和直播来交流。
这种交流方式虽然更加便捷，但却会导致社交疏远和沉迷。
另一个与社交媒体相关的问题是信息过载。
我们现在有许多不同的渠道来获取新闻和信息，包括Facebook、Twitter和Instagram。
然而，由于社交媒体上的信息源太多了，我们很可能会错过关键信息，或者被假信息所误导。
这也导致了社交媒体上的假新闻横飞和流言蜚语的传播。
除此之外，社交媒体也成为了一种由偏见和偏见主导的环境。
由于算法的缘故，我们往往只会看到和自己观点一致的信息和意见，而忽略了其他的观点。
这导致了我们越来越难以理解别人的立场和情感，从而使我们的社交技能和同理心退化。
那么，社交媒体如何应对这些问题呢？首先，我们可以限制社交媒体使用的时间和频率。
设定一个固定的时间来浏览社交媒体，可以帮助我们更好地控制自己的时间和注意力。
其次，我们应该多关注多元化的信息源，以获取更全面、准确的信息。
选择合适的信息来源可以帮助我们过滤掉虚假信息和偏见。
最后，我们可以尝试多播放社交媒体平台上不同的来源，并保持开放的心态，以避免陷入偏见和偏见的陷阱。
总之，社交媒体的普及改变了我们的社交方式和信息获取方式。
然而，随着时间的推移，我们已经认识到社交媒体可能会导致与沉迷和偏见有关的问题。
通过采取适当的措施和增强社交技能，我们可以更好地利用社交媒体的优势，进而避免它的陷阱。

（写作知识）如何写好TopicSentence-高级英语写作-北外网院论坛之家-Powe...[写作知识]如何写好Topic Sentence本帖最后由 Tdengyajiao 于 2010-4-1 15:08 编辑如何写好Topic SentenceImportant Topic Sentence in a PassageThe topic sentence properly used can achieve unity in the paragraph, which indicates the importance of the topic sentence.But what is the topic sentence? The topic sentence is an EMPHATICALLY placed, EXPLICIT statement of the central idea in a paragraph. A good topic sentence in a paragraph will help the writer to focus on his subject, prevent him from introducing unrelated material.How does a topic sentence work then? A topic sentence does two things:1) it lays down the subject2) it puts forth the main idea about the subjectsuppose we are asked to write a paragraph on each of the following subjects:1)Subject: MusicFocus: … is interesting and enjoyable.2)subject: Educationfocus: … is very important in the modern world.3)Subject: DramaFocus: I like …Now we have some topic sentences (which may or may not be good topic sentences—that is the question we are going to discuss below). Clearly each of the topic sentences has two parts: a subject and something said about the subject, we can call it the focus.But are they good topic sentences? Surely not! Take the subject “music” for instance.Ask ourselves, “what do we mean by music? What kind of music? Do we mean symphonic music, chamber music, pop music or other sources? How can we cover so many types of music in one paragraph? Or in a short article of 150 to 200 words?”Focus: … is interesting and enjoyable.Ask ourselves again, “ what do we mean by interesting and enjoyable? Look in a dictionary, interesting—exciting curiosity or attention, enjoyable—agreeable. These two words don’t say very much about music. They simply express approval and they are FAR TOO VAGUE for a good topic sentence.We can find that “Music is interesting and enjoyable” makes a bad topic sentence—bad because the subject is too broad; bad because the focus is vague.(Could you provide a satisfying topic sentence for the subject "music"??)The same is true of each of the following examples:Science fiction is always exciting.Water pollution is a big problem.Life began in a strange way.What makes good topic sentences then? A good topic sentence has a limited subject and a sharp focus. That is, neither too general nor too narrow. A topic sentence that is too general leaves little to be said in the rest of the paragraph. Too general requires much more paragraphs to develop it.Here are some simple, factual statements that are too narrow to require any development or support:1)I live in an apartment.2)Last summer I worked as a gas station attendant.3) Many children watch cartoons on Saturday morning.The following, in contrast, are assertive statements that we can write about in a paragraph1) Living in an apartment has its drawbacks/advantages.2) Working as a gas station attendant was the worst job I ever had last summer.3) Some experts feel that violence in cartoons is bad for children.You can provide better topic sentences than that of the above. Why not have a try?Exercises: revise the following topic sentences to narrow the focus by stressing a controlling idea.Eg. Original: Today many young people have developed a culture of their own.Revision: Long hair, colorful clothing, and new musical forms are part of the new culture of many of today’s young people.Eg. The Santana is a fine car.à Super engine performance and beautiful design make the Santana a find automobile.1) Participation in college sports is beneficial.2) Motion pictures should be censored.3) People could make a better use of their leisure time.4) China should take a stronger role in world affairs.5) Studying a foreign language is useful.6) Online education is becoming more important every year.( No fixed answer to each question. Please provide your answer and let’s have some discussion here)MORE EXPLANATION ABOUT TOPIC SENTENCE-------------------------------------------What is a topic sentence?A topic sentence states the main point of a paragraph: it serves as a mini-thesis for the paragraph. You might think of it as a signpost for your readers—or a headline—something that alerts them to the most important, interpretive points in your essay. When read in sequence, your essay's topic sentences will provide a sketch of the essay's argument. Thus topics sentences help protect your readers from confusion by guiding them through the argument. But topicsentences can also help you to improve your essay by making it easier for you to recognize gaps or weaknesses in your argument.Where do topic sentences go?Topic sentences usually appear at the very beginning of paragraphs. In the following example from Anatomy of Criticism, Northrop Frye establishes the figure of the tragic hero as someone more than human, but less than divine. He backs up his claim with examples of characters from literature, religion and mythology whose tragic stature is a function of their ability to mediate between their fellow human beings and a power that transcends the merely human: The tragic hero is typically on top of the wheel of fortune, half-way between human society on the ground and the something greater in the sky. Prometheus, Adam, and Christ hang between heaven and earth, between a world of paradisal freedom and a world of bondage. Tragic heroes are so much the highest points in their human landscape that they seem the inevitable conductors of the power about them, great trees more likely to be struck by lightning than a clump of grass. Conductors may of course be instruments as well as victims of the divine lightning: Milton's Samson destroys the Philistine temple with himself, and Hamlet nearly exterminates the Danish court in his own fall.The structure of Frye's paragraph is simple yet powerful: the topic sentence makes an abstract point, and the rest of the paragraph elaborates on that point using concrete examples as evidence.Does a topic sentence have to be at the beginning of a paragraph?No, though this is usually the most logical place for it. Sometimes a transitional sentence or two will come before a topic sentence: We found in comedy that the term bomolochos or buffoon need not be restricted to farce, but could be extended to cover comic characters who are primarily entertainers, with the function of increasing or focusing the comic mood. The corresponding contrasting type is the suppliant, the character, often female, who presents a picture of unmitigated helplessness and destitution. Such a figure is pathetic, and pathos, though it seems a gentler and more relaxed mood than tragedy, is even more terrifying. Its basis is the exclusion of an individual from the group; hence it attacks the deepest fear in ourselves that we possess--a fear much deeper than the relativelycosy and sociable bogey of hell. In the suppliant pity and terror are brought to the highest possible pitch of intensity, and the awful consequences of rejecting the suppliant for all concerned is a central theme of Greek tragedy.The context for this passage is an extended discussion of the characteristics of tragedy. In this paragraph, Frye begins by drawing a parallel between the figure of the buffoon in comedy and that of the suppliant in tragedy. His discussion of the buffoon occurred in a earlier section of the chapter, a section devoted to comedy. The first sentence of the current paragraph is transitional: it prepares the way for the topic sentence. The delayed topic sentence contributes to the coherence of Frye's discussion by drawing an explicit connection between key ideas in the book. In essays, the connection is usually between the last paragraph and the current one.Sometimes writers save a topic sentence for the end of a paragraph. You may, for example, occasionally find that giving away your point at the beginning of a paragraph does not allow you to build your argument toward an effective climax.How do I come up with a topic sentence? And what makes a good one? Ask yourself what's going on in your paragraph. Why have you chosen to include the information you have? Why is the paragraph important in the context of your argument? What point are you trying to make?Relating your topic sentences to your thesis can help strengthen the coherence of your essay. If you include a thesis statement in your introduction, then think of incorporating a keyword from that statement into the topic sentence. But you need not be overly explicit when you echo the thesis statement. Better to be subtle rather than heavy-handed. Do not forget that your topic sentence should do more than just establish a connection between your paragraph and your thesis. Use a topic sentence to show how your paragraph contributes to the development of your argument by moving it that one extra step forward. If your topic sentence merely restates your thesis, then either your paragraph is redundant or your topic sentence needs to be reformulated. If several of your topic sentences restate your thesis, even if they do so in different words, then your essay is probably repetitive.Does every paragraph need one?No, but most do. Sometimes a paragraph helps to develop the same point as in the previous paragraph, and so a new topic sentence would be redundant. And sometimes the evidence in your paragraph makes your point so effectively that your topic sentence can remain implicit. But if you are in doubt, it's best to use one.。
topicsentence英语主题句
topicsentence英语主题句讲解主题句是一个完整的句子，用以概括、叙述或说明该段落的主旨大意。
每一个段落只能有一个主题，全段的其他文字都应围绕它展开。
主题句通常由两部分组成，即主题(topic) +中心思想（controlling idea）。
中心思想的作用是导向(control) 和制约(limit) 主题。
所谓导向就是规定段落的发展脉络，所谓制约就是限制主题的覆盖范围，两者不可分割。
没有导向，内容就会离题或偏题；没有制约，内容就可能超出一个段落所能容纳的范围。
下面的8个句子都是很漂亮的主题句，其中红色加粗的文字为主题，绿色斜体的文字为中心思想：1. People can avoid burglaries（入室行窃）by taking certain precautions.( 接下来作者将围绕着“防范措施”展开段落)2. There are several advantages to growing up in a small town.( 接下来作者将围绕着“优点”展开段落)3. Most US universities require a 550 point TOEFL score for a number ofreasons.( 接下来作者将围绕着“原因”展开段落)4. Fixing a flat tire on a bicycle is easy if you follow these steps.( 接下来作者将围绕着“步骤”展开段落)5. There are several enjoyable ways to travel between the US andQueretaro.( 接下来作者将围绕着“方法”展开段落)6. Effective leadership requires specific qualities that anyone can develop.( 接下来作者将围绕着“品质”展开段落)7. Industrial waste poured into Pearl River has led to dramatic changes inits ability to support marine life.( 接下来作者将围绕着“变化”展开段落)8. In order to fully explore the wreck（残骸）of the Titanic, scientists mustaddress several problems.( 接下来作者将围绕着“问题”展开段落)通过对上面8个主题句的分析可见：段落的主题句对主题的限定主要是通过句中的关键词来实现的。
a new topic sentence英语作文
a new topic sentence英语作文是Essay中心句(Topic Sentence)？当然中心句需要概括本段的主旨都知道的。
但是具体怎么写Essay中心句呢？中心句的两大要素分别为：topic+controlng idea。
其实也就是说，首先中心句要有关于一个话题，其次中心句必须是一个观点句，关于这个话题你到底具体到写哪一个点，需要在你的里明确。
看例子：1）Smarts can be expensive.这句话里，topic是arts,controlng idea是can be expensive.可以预测这段话的内容会阐述为智能会比别的贵。
2）Information on the internet is not reable.这句话里，topic 是information on the internet,controlng idea是is not reiable.我们也可以预测后面的内容应该是说为的息不可靠。
Essay中心句(Topic Sentence)写作需要注意：1）中心句只针对body paragraph，开头和结尾段是没有写中心句的必要的。
因为这两段的每一句都很重要，是这个的主体。
以后我们还会专门讲introduction和conclusion怎么写。
2）Essay写作中，中心句应该是关于一个话题的观点句，只有一个观点句才有的必要。
而且中心句的话题和观点还不能太大也不能太窄。
太大的话题一段话写不完，太窄的话题没有内容可以写，比如， is an ancient country with gloous tronditional hetages.这个句子作为一个段落的中心句太大了，在一段话里你是详细阐述的。
3）中心句由topic+controlng idea构成，也就决定了段落其他内容必须和中心句内容相关。
这个叫做写作里要遵守的unity原则，说的简单一点，就是不要说废话。
说的每一句话都要和中心相关。
