1、2017年10月托福真题回忆及解析2017年10月托福真题回忆及解 场考试，考试时间为10月15日。以下内世上的事，只要肯用心去学，没有一件是太晚的。你只要记住你的今天比昨天进步了一点, 那么你离你的梦想也就更近了一步。无忧考网搜集整理了 析，希望对大家有所帮助。2017年10月举行了 1 容仅供参考。10月15日托福听力真题回忆:Con versatio n 1A话题分类学生和工作人员可以参加训练（有题）。教授说有个 所以她们不熟悉。这个学生现在还没来,内容回忆女生的ankle 之前受伤，说自己的伤好得差不多了， 新的assistant要来，之前不是这个女生一队的，还在加州（双选）。教练希望

2、作为女生作为队长的女生可以用一些经费带两个球队的成员 请新assista nt吃饭表示欢迎。但女生觉得其他人会觉得left out（有题），所以建议用这些钱办一个欢迎party，买一些零食吃。而借场地方面，本来教授要去预定，但学生，而这个地方学生只要sig n up 就可说她室友曾借过firep lace旁的一个场地（双选）以使用。参考听力TPO 43C2Con versatio n 2A很感兴趣，想把final pap er 的题目 outli ne写的太宽泛了，应该关注特定话题分类 学生和教授 内容回忆学生对教授给的网站中 un dergro und architecture换成这个。教授

3、说之前的top ic其实不错，只是的点，并给出解决方案（有题）。这种建筑要用到新的tech nology ，举例纽约的一个公园，里面还有pla nt（有题）。学生觉得虽然这种建筑存在很久，但还是没有大规模的，教授最后讲到土耳其在很久前有个超 大的地下城市（重听）。参考听力TPO 28C1Lecture 1A话题分类艺术类内容回忆讲一位叫Thomas的著名landscape 画家。那时候大家一般花portrait（有题），但这个人出去玩了一圈，到了一个山和一个湖被自然吸引，回家后开始画风景画（有题）。最 开始他的一幅画被工匠裱起来摆在橱窗里展示，被一个有名画家看到买了下来（有题）， 这个人一直很

4、支持 Thomas，最后还把他介绍给自己的朋友。慢慢的Thomas就开始出名了，成了风景画运动的founder （有题），很多后辈都会有些和Thomas相同的特征。讲了一幅画的细节，clouds，被闪电击倒的树都传递了感情（有题）。参考听力TPO21L4， TPO24L2Lecture 2A 话题分类 生物类 内容回忆Green patches/ island 现象是指秋天大部分叶子变黄时，有些叶子局部仍是绿色的，这 是因为一些 C 细菌。一些虫子在上面产卵，这种 island 给他们提供更多的营养来 reproduce 。后来讲到这种细菌的产生方式，用苹果树做的实验。一个解释是虫子分泌的，

5、另一个是说虫子 trigger 苹果树产生过量的这种物质。参考听力 TPO43L1 Lecture 3A 话题分类 心理学 内容回忆 心理状态会影响未来预期。教授先解释概念，男生问是否指如果很饿就会觉得未来有大量 食物（重听）。教授更正学生说法，是只有吃的很饱的时候，会觉得未来的食物会一直丰 盛。科学家做了三个实验通过研究暖和的天气和未来全球变暖的可能性来验证这关系。实 验一：户外的持续很多天的实验，最后发现比较 warm 的天气大家会觉得 global warming 更有可能，但学生就觉得现在全球变暖的新闻会影响对未来的预测，或者根据外界天气产 生的预测。实验二：在室内（为了避免外界温度影

6、响）做了实验，结果和实验一是一致的。 但也存在问题：人们可以根据屋内温度推测室外温度，如果外面很冷，里面也不会很暖和。 实验三：在一个可调节温度的屋子里，最后结果还是一样的。说明这个状态是会影响到未 来的预期。参考听力 TPO15L1 Lecture 4A 话题分类 天文类 内容回忆Supernova 的形成。 Supernova 是 star 爆炸后产生的 massive illuminated object。它star 主要由氢气和氦 。时间越长，一个 wind 越厉害。这个 wind 会导 galaxy 会有质量比较大的行星。最后说由于一种 ，所以发现了 dwarf galaxy （有题

7、）。一般存在于一个很小的，相对形成时间较短， dwarf galaxy 里（三选）。最开始科学家没 找到对应的 galaxy ，因为 supernova 本身太亮了，可能 galaxy 太小太暗。后来降到 supernova 大小和 galaxy 形成时间的关系。在刚开始形成的时候， 气组成，慢慢 fuse 成 dense elements 致行星质量减少。所以相对形成较晚的 新型的 telescope 能检测 radiation 参考听力 TPO19L2 Conversation 1B 话题分类 学生和篮球教练 内容回忆 学生找工作人员抱怨停车位不够。她买了停车位，但每天到学校都没有位置，只

8、能停在校 外马路上，还要另付停车费。工作人员问学生是否更改过课表，发现学生之前是下午上课， 现在是上午上课。也是因为职工早上的时候也会占用学员的车位，所以车位紧张。然后说 现在有两个停车场在建，不过要两年后建成。然后说可以给学生一部分退款，学生说晚上后来画家去伦敦后，绘画较为夸张，天空太蓝，光线太亮，最后说到去网上来图书馆还是需要停车，最后建议骑自行车或者公共交通来学校，缓解停车问题。 参考听力 TPO42C2 Conversation 2B 话题分类 学生和教授 内容回忆 学生问教授一个意大利画家关于威尼斯的画。学生觉得过于真实，没有角度。教授解释这 画是为了 旅行者而画。帮助学生写论文。T

9、PO27C2搜索该画 家后续画作，生物类一种是 biological clock ，一种是和细胞 damage accumulation 。重点讲第参考听力 Lecture 1B 话题分类 内容回忆 解释 aging 。 二种。提到节食 可以延长寿命，因为 metabolism 降低， damage 降低；但是又有一种说法是节食提高了 metabolism ， 然后 activate a gene 。TPO45L2文学类的起源。 19 世纪初 A Lane 这人坐火车时想买小说上车看，结果都是厚重penguin book ，里面有 9 篇小说，参考听力 Lecture 2B 话题分类 内容回忆

10、 讲 paperback 的小说，不方 便携带。他想出了一种简单便携的小说书。后期创办了 封面就是 企鹅，并用不同颜色标注不同种类的小说。TPO43L3历史类plow 没法中世纪人口扩张，导致食物减少，土地资源减少。农民之前用的参考听力 Lecture 3B 话题分类 内容回忆 农业发展史， 耕作更深的 土地，所以发明了 heavy plow。同时农民发现马比牛耕地更快，所以更多地用马耕地运输。由于马 的使用，耕地面积进一步扩大，并且每年有一部分土地休整。TPO29L3天文类参考听力 Lecture 4B 话题分类 内容回忆 Europa 行星，是 Jupiter 的卫星，上面可能有生命存在。

11、对比了地球生命的形成，提到 Jupiter 的引力有助于Euro pa的ice break，产生氧气，同时星球上有水源，可能会有早期生命形态。 人类有一个breaker计划，帮助Euro pa海洋水破冰，产生氧气。不确定这是否有用，而且即使有用, 也可能要很多年。参考听力TPO30L3 TPO41L4 10月15日托福写作真题回忆:综合写作话题分类历史类总论点在Northeast Russia发现了一些labyrinth，关于其作用，阅读提出了三种可能的假设，听力一一予以反驳。阅读部分1.

Spend more time talking with their children - parents can find out the reason for misbehavior or bad behavior, so as to give suggestion to their childrenresentment2. Limit th

18、e typesof TV programs or films - will not help/ only lead toand rebellion3. Monitor and supervise children ' s activitieswith their friends - children willnot feel at ease/ they cannot enjoy their time with friends 参考范文Someparents complain of the improper behavior of their children and they try

19、every means to rectify such behavior. Normally, they resort to three ways, namely, restriction of forms of entertainment, face-to-face conversations, and supervision over their children. Amongthe three options, I think the most effective one should be to spend more time talking with their children.A

20、 face-to-face talk can reveal many things that are otherwise kept hidden or unnoticed. This will in the end solve a lot of problems. In fact, the reasons for improper behavior or misbehavior vary among children, and it is almost impossible for parents to really tackle the problem without finding out

21、 the reason for such behavior. For example, a child may choose to draw graffiti on the wall simply because they have seen others do it and found it cool to imitate, totally oblivious to the trouble that might be brought about by such conducts to their parents. Without a proper talk with their childr

22、en, the parents might mistake such behavior for a deliberate rebellion against the parents and might resort to harsh punishment, which can only worsen the result. Also, sometimes misbehavior is one way of saying“ Iwant your attention. ” When neglected, some children may choose to hurt themselves so

23、as to win attention from their parents. In this case, spending time with children proves to be the most effective way of eliminating such behavior.Limiting the types of TV programs or films, on the other hand, will not achieve the intended purpose. This is because, despite the firm belief of some pa

24、rents, there is no correlation between children' s misbehavior or improper behavior anddeemedto fuse friends. with their friends iscertain types of TV programs or films. Children will not necessarily become violent if they have watched some so-called violent cartoons or movies, nor will they use

25、 improper language if they have watched some shows not intended for them. In fact, many TV programs and films have all filtered out things that are universally improper to children, so that exposure to them is not as harmful as the parents choose to believe. Besides, restricting the types of TV prog

26、rams or movies will only lead to resentment or rebellion, since children may find it difficult into their circle of friends if they cannot share the sametopics with their Likewise, monitoring or supervising children ' s interaction also not an effective way. Normally, with the presence of parent

27、s, children willnot feel at ease, so they can hardly enjoy themselves when playing with their friends. This is because many games popu lar among childre n would be regarded as improper or dangerous in the eyes of the parents, and thus be totally forbidden by the parents. Their friends may also feel

28、awkward under the supervisionfrom a stranger,so theymay choose to stop coming by and p lay ing. As a result, their childre n will soonbe left alone with no one to play with, which only con tributesto more misbehavior.In conclusion, if parents want to rectify their children s behavior, the mostsen si

Evidence points to hunting by humans and habitat destruction as the likely causes for the current mass extinction. American paleontologists David Raup and John Sepkoski, who

41、resence of the rare-earth element iridium (Ir). Earth 's crust contains very little of this element, but most asteroids contain a lot more. Debris thrown into the atmosphere by an asteroid collision would presumably contain large amounts of iridium, and atmospheric currents would carry this mate

42、rial all over the globe. A search of sedimentary deposits that span the boundary between the Cretaceous and Tertiary periods shows that there is a dramatic increase in the abundance of iridium briefly and precisely at this boundary. This iridium anomaly offers strong support for the Alvarez hypothes

The intense heat of the impact would produce heat-shocked quartz in many types of rock. Also, large blocks throw

To date, several such secondary craters have been found along Mexico ' s Yucatan Peninsula, and heat-shocked quartz has been found both in Mexico and in Haiti.

46、rger, mass extinction at the end of the Permian period (around 250 million ago). The Permian event has attracted much less attention than other extinctions because mostly unfamiliar species perished at that time.1.Paragraph 1 supports which of the following statements about mass extinctions?
