托福阅读出题“常跪”陷阱被K过？
踩坑了！托福阅读出题“常跪”陷阱被K过？举例来看出题人陷阱！get到了！为了让大家更好的进行复习和备考，应对即将到来的考试月，今天跟大家解密一种阅读出题“常跪”陷阱，无中生有的错误选项！
托福阅读出题“常跪”陷阱被K过？
无中生有，这是阅读错误选项编排过程中非常常见的一种惯用手法，主要就是编造一些有道理、能讲通的的选项来迷惑大家。
因为绝大部分的选项之所以不选都是由于选项内容与原文内容矛盾，当有一个选项本身没有什么错误而且还有点道理，这样的选项就会让大家陷入纠结。
我们来共同看一下下面的例题：
Watt's steam engine soon showed what it could do. It liberated industry from dependence on running water. The engine eliminated water in the mines by driving efficient pumps, which made possible deeper and deeper mining. The ready availability of coal inspired William Murdoch during the 1790s to develop the first new form of nighttime illumination to be discovered in a millennium and a half. Coal gas rivaled smoky oil lamps and flickering candles, and early in the new century, well-to-do Londoners grew accustomed to gas lit houses and even streets. Iron manufacturers, which had starved for fuel while depending on charcoal, also benefited from ever-increasing supplies of coal: blast furnaces with steam-powered bellows turned out more iron and steel for the new machinery. Steam became the motive force of the Industrial Revolution as coal and iron ore were the raw materials.
In this paragraph， the author mentions William Murdoch's invention of a new form of nighttime illumination in order to
●indicate one of the important developments made possible by the introduction of Watt's steam engine
●make the point that Watt's steam engine was not the only invention of importance to the Industrial Revolution
●illustrate how important coal was as a raw material for the Industrial Revolution
●provide an example of another eighteenth-century invention that used steam as a power source
上面的这道题目属于阅读必考题型修辞目的题，主要的做题流程是找到例子William Murdoch's invention和论点句Watt's steam engine soon showed what it could do之间的关联。
两句话之间，还贯穿解释内容，如瓦特蒸汽机的出现能够让挖煤工作进展顺，更多的煤就激发了William Murdoch去发明了一种新型的夜间照明系统。
所以，这个题目的答案应该是A选项。通过William Murdoch's invention来侧面指出瓦特的蒸汽机的发明促进了其他行业的发展，如上是正确的思考思路。
但是，我们可以再关注一下选项B：指出观点瓦特的蒸汽机不是唯 一重要的发明与C：解释煤是多重要的原始材料对于工业革命的发展这两个选项。
从道理上来讲，B,C两个选项都存在着它们各自的正确的可能和合理的角度，但是我们不能选，就是因为文章中作者并不是想要突出如上两个内容，所以这两个选项就是有点道理，但不选的选项。
把上面的一道题目仔细品味以后，大家就能对无中生有做出明确的体会了。
这个“常跪”陷阱是托福考试中超高频导致扣分的陷阱，希望下一次大家再分析选项的时候，能够从容拿捏他的特定角度合理性，再排除选项的时候，能够看透它并非作者文章意图的错误编排。

托福听力如何从小白到大神的三个阶段
托福听力备考—如何从小白到大神的三个阶段?对于托福听力的备考来说制定一个适合自己的备考计划还很必要。但是提醒大家的是，对于要参加考试的同学来说是有不同阶段的，从开始准备一直到托福听力训练，这些是托福听力学习中不可少的部分。
托福听力如何从小白到大神的三个阶段
对于托福听力的备考来说，制定一个适合自己的备考计划还是相当必要。但是，需要提醒大家的是，对于要参加考试的同学来说是有不同阶段的，从开始准备一直到托福听力训练，这些都是托福听力学习中不可少的部分，下面来看看这个问题。
准备阶段：
一、词汇的积累。词汇是任何一门语言的基石，托福听力训练中积累的词汇量是应考的先决必要条件。建议考生熟记托福高频词汇，做到音形意统一背诵，即听到发音即能立刻反应单词的拼写和中文意思。
二、语法的精通。如果说词汇是基石，那么语法就是粘合剂，把基石垒成高楼大厦。托福听力中出现的虚拟语气，强调句，定语从句，倒装句等都会给听力内容的理解带来一定障碍，所以要熟悉一些重要语法，对提高听力的理解能力至关重要。
备考阶段：
一、 听写训练。有了上面词汇和语法的积累，可以进行听写训练提高听力。材料可以用iBT的TPO以及老托福Part C的Lectures，这样保证和考试话题的一致性，天文地理历史人文等。第 一步要总听全文，寻找逻辑，即了解文章的大概内容，不要陷入细节。第二步听一句写一句，能写几个单词写几个单词，不会写的记住声音符号，用音标汉字等方式标注。第三步对实在听不懂的句子对照原文反复琢磨找到听不懂的原因。第四步跟读全文，复述。
二、 如何记笔记。在托福听力学习中，记笔记的原则是自己记的能看懂，中英文符号线条图画等并用，简练，切莫因记误听;记录文章开头结尾，解释程序的步骤顺序，重要时间地点，人物身份观点，原因结果，优缺点等。
三、 分析题型及文章结构，了解外国人的思维方式，总结考点。在备考阶段，如果做TPO，则要把每套题做精做透，把话题进行分类(天文地理等)，把做错的题要仔细解析原因。
四、 做整体模考训练的过程中，一要练习耐力和注意力，由于托福听力持续时间较长，要在平时的训练中就注意耐力和集中注意力的训练;二是在噪音环境中训练，在实际考试考试过程中，难免有一些意外的杂音和声响可能会引起分神，在训练时可以适当打开电视进行干扰训练;三是速度的训练，在对普通语速的听力都能听懂之后，可以适当加快对话的速度，训练考生的反应能力。
实战阶段：
一、 进考场之前，要每天听TPO Lecture等，俗话叫灌耳音，保持耳朵对英语的辨识度和敏感度。
二、 要调整好自己的心态，保持积极向上的态度和充足的信心。
三、 要注意答题时间的掌控，由于托福听力答题时间为17道题10分钟，所以每道题的思考时间有限，请要顾全大局，切莫顾此失彼。

托福独立写作真题范文
托福独立写作真题范文 ：现在的学生比以前更关心政治了吗？
7月4日托福独立写作真题范文
托福独立写作题目
Students are more interested in politics than they were in the past. Do you agree or disagree?
1
To get a sense of whether current students are interested in politics, social media, which dominate the way students get informed, are a good place to start. With more students posting comments on political issues online, people are put under a illusion that they are interested in politics. As a matter of fact, current students are less likely to be intrigued by politics than did their counterparts of the past.
重点词汇：
* To get a sense of xxx, .... is a good place to start 为了了解某事，... 是个好的切入点。
* Under the illusion 在xx幻觉之下
* Intrigue v. 引起兴趣
* Counterpart n. 对应的事物
2
It is indeed easier for students, who are exposed to a deluge of news online, to be politically aware today. With information about what’s happening both at home and abroad at their fingertip, it seems that social platforms have ignited students passion for politics. However, would they truly reflect on the political news when browsing social media? The fact is that with most news online presented in short videos with catchy headlines, students may simply glance over the title or mainly focus on the funny moments when a politician makes a verbal slip. Even if they may briefly skim the highlight of a report, they may be too lazy to think about the implications or rationales. Sadly, they may wrongly assume that they have fully learned about the complex event by doing this.
段落解析：
本段内先转折说明尽管学生看的很多，但其实他们只看标题和搞笑的内容，但缺乏深度思考，所以不是真正的感兴趣。而至于与过去的对比，不妨留至下段展开。
重点词汇：
* At one’s fingertip 触手可及
* Glance over 粗略浏览
* Make a verbal slip 口误
3
Although past generations of students did not enjoy the same convenience brought by social media, they are more absorbed by each piece of news on the latest political events, either through newspapers, cable TV or word-of-mouth. And more importantly, they were very vocal in the inequalities like unfavourable policy for women or the minorities, and the demonstration aiming to stop Vietnam War as well as civil rights protest engaged thousands of them. By stark contrast, students nowadays who read a lot online and discuss freely within the class may become ironically silent when it comes to actually do something.
段落解析：
本段完成与上段的对比，说过去的学生不像现在的学生，不但看，而且思考，而且有所行动。这才是真正的感兴趣。
尽管现在的学生可以用过社交媒体读到大量的政治新闻， 而过去的学生不能。但我们不能误以为（be put in the illusion that）学生就对政治感兴趣了。因为现在的学生读政治新闻只粗略（skim; glance over） 浏览标题或者只关注搞笑的部分，而不仔细思考(reflect)。而过去的学生，尽管资源有限，但是会细细思考及激烈讨论。更重要的是，他们还会积极地为政治事件发声。
重点词汇：
* Absorb v. 被吸引
* Vocal adj. 直言不讳的
* Demonstration n. 游行
4
Additionally, in the past, students had little to do other than unfolding a newspaper or playing instruments in their dorms, and they were therefore more likely to allocate time for politics. This is different from now, when students have more activities to do during their free time in dorms. For example, they can now play engaging video games rather than reading boring political report written in obscure language; and they can gossip about films or celebrities instead of debating over political events that provoke thoughts. In this case, how could they be interested in politics?
重点词汇：
* Engaging adj. 引人入胜的
* provoke thoughts 煽动思绪
5
In conclusion, it seems easier to be politically active now than it was in the past, but current students’ nonchalance about politics seems to be the norm rather than the exception.
重点词汇：
* be the norm rather than the exception 常见

小托福听力考试内容及题型是怎样的？
虽然小托福考试和托福考试在面向人群及考试题型上有区别，但是都是要考听力的，那么大家知道小托福听力考试内容及题型是怎样的吗？我们准备一项考试，首先要去了解它，考试内容，考试题型这些都是我们需要提前了解的内容。
小托福听力考试内容及题型是怎样的？
一、 Class Instruction部分
1、内容
主要考察学生理解非学术性质的指导用语的能力。内容涉及通知、说明或者课堂注意事项。
2、题型
主旨题、推断题和预测题。（其中50%主旨题）
3、考点分析
（1）话题的大意。开头主题句是解答主旨题的"捷径“。少数文章没有主题句，需要归整个段落的大意。
（2） 其他题型需通过题干关键词来定位。对于推断题， 要根据上下文息做出推理；对于预测题，要关注提示下一步动作的关键词句（如：You will need to…）
二、Conversation部分
1、内容
对话交流能力，内容包括课堂内容讨论、作业讨论、校园生活话题。
2、题型
主旨题、细节题、推断题、预测题、语气题以及修辞结构题等。
3、考点分析
（1）话题的大意
（2）重要细节定位（如学生的问题， 态度以及持该态度原因，下一步要做什么等）
（3）推理的能力
（4）理解说话者意图的能力。学生需要理解特定语调、重音所表达的态度。
三、 Academic Talk& Discussion部分
1、内容
该部分测试了听懂学术话题的能力。有老师单一演讲以及和学生互动两种类型。话题分为艺术、生命科学、自然科学、社会科学四类。
2、题型
涉及到大多数题型，包括主旨题、细节题、推断题、预测题、语气题以及修辞结构题。
3、考点分析
和conversation大致相同。Lecture比较容易考察修辞理解题，要注意演讲者演讲中的修辞手段（举例子，类比和对比，原因和结果等等 ）。
小托福听力考试内容及题型是怎样的现在大家有了解了吗？对考试的内容及题型有了解后，大家在下来就要根据考点及个人情况做好备考规划了哦!
课程小结
托福听力考试涉及的一个话题——天文
讲了这么多期天文学的背景知识，相信大家已经对于天文学领域的一些常见概念有了比较清晰的了解。我们今天来讲一个非常有意思的内容，也是很多天文学讲座中非常喜欢涉及的一个内容——宇宙中是否还存在其他的生命呢？或者其他的生命形式？今天就来说一说这个话题的内容。
托福听力考试涉及的一个话题——天文
我们知道宇宙非常大，大到我们根本没办法想象的程度。就目前我们所有观察到的，就有不计其数的星系，每个星系还包含有不计其数的星体。同时，科学家也在不断地发现星体。就银河系本身来说，或许也会有很多大小合适、温度合适的星球，这些星球具备存在生命的条件，但是现在科学家又没有足够的证据，去进行证明，现在，除了地球是有生命存在的，目前还没有发现任何其他的星球也存在生命。
但是努力探索，是科学家们宝贵的精神，很多科学家也做出过对于一些星体上可能存在生命物质的判断，还有一些科学家也尝试过去探索类地行星，致力于去寻找这么一个和地球很相像的可居住星球。而这个内容，是很多天文学讲座喜欢去触及的。下面，我截取出来一部分天文学讲座的内容，给大家感受一下，关于这个主题，文章的内容部分一般怎么展开以及部分题目会如何考察，比如下面这篇文章：
(male professor) So, we’ve been searching for stars similar to our Sun, what we might call sun-like stars, since presumably planets orbiting such stars are the most likely to have liquid water, a requirement for life as we know it. And what mostly determines whether liquid water can exist, of course, is the planet’s temperature. Too hot or too cold and any water would either vaporize or freeze. OK, but this assumption that stars with habitable planets must be sun-like, radiating huge amounts of thermal nuclear energy, this might not be actually necessary.
Yes, Stephanie?
(female student) Where would the planet get its heat then?
(professor) One possibility is that it could orbit a different kind of star, a white dwarf. Do you remember what a white dwarf is?
(female student) It’s a dead star, like the ember that’s left after a star has burned up all its fuel but it’s cooler and dimmer than sun-like stars, right? And much smaller.
(professor) True. But there are still enough energy in their core to generate some heat. Now, to get enough heat for liquid water, a planet would need to orbit its white dwarf very tightly.
(female student) But before becoming a white dwarf, doesn’t a star first expand and then collapse? And wouldn’t the expansion phase destroy any planets closest to it?
(professor) Yes, but, some outer planets could survive and move closer in. Or new planets could form after the star collapses. White dwarfs exist for many billions of years. So there’s plenty of time for such changes to occur.
(female student) There aren’t that many white dwarfs in the universe, though. Are there?
(professor) Actually, we’re finding that they are plentiful in the universe. We detect them in an indirect way. When a planet passes in front of its host star, this transit eclipses some of the star’s light. By measuring this periodic dimming, we infer the existence of a planet. Since white dwarfs are only slightly bigger than Earth, a planet might block out 50 percent of the white dwarf’s light, which is observable through a ground-based telescope. The transit of a planet orbiting a sun-like star produces just a miniscule change in luminosity.
......（未完待续）
2. Why does the student talk about how a white dwarf forms?
A) To demonstrate her familiarity with the life cycle of stars
B) To speculate about the ultimate fate of the Sun
C) To suggest a topic to explore in a future class discussion
D) To question a hypothesis described by the professor
3. What factor makes it relatively easy to detect planets orbiting a white dwarf?
A) The planets typically reflect a significant amount of light.
B) The planets block a significant amount of the star’s light during transit.
C) The planets have a higher mass than the white dwarfs that they orbit.
D) Planets around white dwarfs have very slow orbits.
这篇天文学讲座，通过文章的开头部分，教授给出了一些背景信息，通过背景信息部分的描述，我们可以看出文章内容是打算围绕星球的可居住条件展开。符合可居住星球的条件未必是像太阳一样的。还有可能是其他类型的星球支持可居住星球，比如：白矮星。接下来，文章下面的部分主要就是围绕白矮星，进行定义、解释以及白矮星具备什么样可以支持可居住星球的条件进行展开。
针对这个部分内容，这里给出大家两个问题，可以尝试去进行一下作答。天文学的讲座很多同学比较排斥、恐惧，事实上，文章内容有时候感觉比较抽象晦涩，但是实际上的考点是比较容易的，都是比较浅显、直白的细节题目，基本上就是原文的某处细节的简单改写。上面2个题目答案分别是：D B。你们都做对了么？

针对这个部分内容，这里给出大家两个问题，可以尝试去进行一下作答。天文学的讲座很多同学比较排斥、恐惧，事实上，文章内容有时候感觉比较抽象晦涩，但是实际上的考点是比较容易的，都是比较浅显、直白的细节题目，基本上就是原文的某处细节的简单改写。上面2个题目答案分别是：D B。你们都做对了么？
