2017年3月11日托福真题回顾Reading:3.11阅读继续保持上期的疯狂趋势，截止目前已经收集到四套题：第一套：荷马史诗松鼠报纸第一篇Homer and Oral Poetry（Literature)P1. 早期的诗歌是被recited and sung, 而不是written. epic poems的最高成就是古希腊Homer的Iliad and OdysseyP2. Iliad和Odyssey是在750 B.C. 到720 B.C. 写的。

I比O早了几十年，导致一个疑问是他们到底是不是一个人写的。

关于他们的Method也有一些争议，既有口头色彩的stock phrase, 也有书面文学long and complex expression.有猜测认为I和O不是Homer一个人写的，而是一些无名人士搜集整理，最后成了我们现在看到的样子。

P3. 观点发生了变化。

有人认为早期oral poem可能是一种再创造，不会读写的人也可能讲出类似的诗歌，他们基于古老的故事内容和固定的模式，通过自己的方式retell the story. P4. Homer也可能是通过这个方式。

他用自己的方式recompose the poem, 从之前的传唱故事吸收了很多固定表达，慢慢展现了自己的风格，通过不停地rehearsal, ,write? in his mind. P5. 到底I和O是何时被written down and fossilized? 大致是接近Homer的时期。

有三种理论：1. 不会读写的Homer口述给别人记录下来； 2. 后人Recited; 3. Homer自己是可以写的，只不过他trained to make oral version. 不管怎样，I和O都代表着Oral poetry的最高成就。

词汇题：1. culmination-high point2. controversy-disagreement3. anonymous-unidentified4. exhibit-display第二篇：Food-Storing strategies of Squirrels(Biology)P1. 精于贮藏食物是Squirrels的特征，简单讲了其中比较典型的territorial pine squirrels store cone的方式。

Beautiful and practical things can simply add some spice to others’ life, and naturally help to leave a good impression. A pretty good example would be my first month in university. Four strangers in a dorm, you know. We were all from different places and barely knew each other except for our names. It would be quite embarrassing if we had nothing to talk about. Luckily, we brought some local specialties, especially some snacks, like mine, smoked dried beef. The next thing we did were breezy chatting and tasting. This strategy actually works almost everywhere: dorms, classrooms, workplaces, you name it.参考题【人际朋友】：20161016-Describe the best way you deal with disagreement with your friends.20161022-Talk about a period of time when one of your friends disappointed you.T 2Preference: Do you prefer to read paper books or electronic books.Sample Answer:I’ve always got my easy answer for this one: paper boo ks and the very reason for this is, without doubt, convenience. As a student, you’ve got to get down a lot of notes when you are doing preview and of course, listening to lectures. I can directly write things down on the paper right beside the parts that I should highlight. And I can surely flip though the pages to have a quick look at them minutes before the pop quizzes. Of course, the electronic versions do have their own merits, but the catch is also obvious: the battery can run out. If you’ve got nowher e to plug it in soon or have no power bank with you, you just can do nothing but to face a dead little machine.参考题【书/电子书】：20161105-Which of the following technological developments have made the greatest impact on students’ lives?1. Electronic books2. Online classes3. Smart phones.20161113-Some people prefer to buy new books while some people would like to buy used books.

2017年托福口语真题T1You will need to accomplish an assignment to do a presentation. Which will you choose?1. Act out a scene from a play(with a partner)2. Explain your review of a novel you recently you read3. Read a selection of poem范文Among the three presentation choices, I would choose to act out a play with my partner. As a literature major, I have been deeply entranced by dramas, accordingly, I'd rather consider acting as a form of amusement than regarding it as a job. To illustrate, I remember the first year in college, I made a rather unusual decision to deliver a performance on Shakespeare's Drama-Hamlet at New Year’s party instead of participating in student’s choir in singing. As a result, the decision paid off since I was granted an acting position at city's drama club, as a reward for my authentic and impressive performance. Ever since then, acting has become part of my daily ritual for my passion and adoration for it never dies out.T2Someone choose to work in a small company or organization with a few workers. Others prefer to work in a large company or organization with thousands of employees. Which do you think is better?范I am in favor of working in a large corporation rather thana small firm because large corporations often are ruled and governed by stable regulations whereas small firm often undergoes management transformations in which causing employees time to adjust and adapt to the new leaderships. Take my brother Jim as an illustration, he used to work as a high-tech personal in a petite firm which was specializing in virtual reality technology. Initially he was so passionate about the job that he barely took any weekends off for his own pleasure, he was so determined that he'd be promoted with such exceptional skills and professionalism. But he was wrong, after a few years, he was spiritually and psychically worn out because the management seats were constantly going through changes and his promotions were never brought up on the agenda because the new supervisors always bring their own personals to take charge in company affairs. Consequently, Jim had no choice but to quit the old firm and join an elite corporation that has business dealings nationwide, his excellent work has soon to be spotted by the management and he was granted promotion in a short term. Therefore, I'm inclined to listen to my brother Jim and work in a large company with stable leadership2017年托福阅读真题词汇in retrospect=reconsiderintensive=extremecollapsed=fall inwardadverse=unfavorablediminish=decreaseaccerlerate=fastergross=overallscenario=version of eventsunprecedented=never before2017年托福托福写作真题范文综合写作题目：Whether the three methods to stop snakeheads fromspreading is feasible.阅读：The reading raises three methods to stop the spread of snakehead fish because it threatens the ecosystem.1. Making laws to prevent people from transporting snakehead fish. Some people in the fish market will illegally transport or release unsold snakehead fish.2. Educating fishers to catch snakehead. If they recognize that people actually can eat snakehead as a food source, they will catch many to eat and to sell.3. Researching some poison to kill the snakehead. Though poison will also kill native fishes in the river, people can restock native fishes.听力：The listening contradicts all methods proposed by the author of the passage and points out their potential problems.1. Even if people do not transport the snakehead, the spread will still continue.The reason is that there are already many snakeheads, and these snakeheads will move to other rivers even without human's efforts, because they can live and move on land as long as they are moist.2. Educating fishers to catch snakehead will not help stop the spread of snakehead. Conversely, it may lead to the increase of snakehead. Because when fishers realize they can make profit by catching snakehead, they will introduce snakehead to other water bodies and raise snakehead in order to catch more snakehead, even this is illegal.3. It is true that native fishes can be restocked; however,poison will also kill some insects and micro organisms, which cannot be restocked. So,native fishes that feed on these insects and micro organisms cannot grow to their original size. This is irreversible.。

2017年托福复习资料模拟试题及答案（五）•The Native American peoples of the north Pacific Coast created a highly complex maritime culture as they invented modes of production unique to their special environment. In addition to theirsophisticated technical culture, they also attained one of the most complex social organizations of any nonagricultural people in the world. In a division of labor similar to that of the hunting peoples in the interior and among foraging peoples throughout the world, the men did most of the fishing, and the women processed the catch. Women also specialized in the gathering of the abundantshellfish that lived closer to shore. They collected oysters, crabs, sea urchins, mussels, abalone, and clams, which they could gather while remaining close to their children. The maritime life harvested by the women not only provided food, but also supplied more of theraw materials for making tools than did fish gathered by the men. Of particular importance for the native tool kit before the introduction of metal was the wide knife made from the larger mussel shells, and a variety of cutting edges that could be made from other marine shells. The women used their tools to process all of the fish and marine mammals brought in by the men. They cleaned the fish, and dried vast quantities of them for the winter. They sun-dried fish when practical, but in the rainy climate of the coastal area they also used smokehouses to preserve tons of fish and other seafood annually. Each product had its own peculiar characteristics that demanded aparticular way of cutting or drying the meat, and each task required its own cutting blades and other utensils. After drying the fish, the women pounded some of them into fish meal, which was an easily transported food used in soups, stews, or other dishes to provide protein and thickening in the absence of fresh fish or while on long trips. The woman also made a cheese-like substance from a mixture of fish and roe by aging it in storehouses or by burying it in wooden boxes or pits lined with rocks and tree leaves. 1.

下面是整理的2017托福复习资料模拟试题及答案，希望对大家有用，更多信息请浏览!The observation of the skies has played a special part in the lives and cultures of peoples since the earliest of times. Evidence obtained from a site known as the Hole in the Rock, in Papago Park in Phoenix, Arizona, indicates that it might have been used as an observatory by a prehistoric people known as the Hohokam.The physical attributes of the site allow its use as a natural calendar/clock. The "hole" at Hole in the Rock is formed by two large overhanging rocks coming together at a point, creating a shelter with an opening large enough for several persons to pass through. The northeast-facing overhang has a smaller opening in its roof. It is this smaller hole that produces the attributes that may have been used as a calendar/clock.Because of its location in the shelter's roof, a beam of sunlight can pass through this second hole and cast a spot onto the shelter's wall and floor. This spot of light travels from west to east as the sun moves across the sky. It also moves from north to south and back again as the Earth travels around the Sun, the west-to-east movement could have been used to establish a daily clock, much like a sundial, while the north-to-south movement could have been used to establish a seasonal calendar.The spot first appears and starts down the surface of the wall of the shelter at different times of the morning depending on the time of the year. The spot grows in size from its first appearance until its maximum size is achieved roughly at midday. It then continues its downward movement until it reaches a point where it jumps to the floor of the shelter. As the Sun continues to move to the west, the spot continues to move across the shelter floor and down the butte, or hill, toward a group of small boulders. If a person is seated on a certain one of these rocks as the spot reaches it, the Sun can be viewed through the calendar hole. This occurs at different times in the afternoon depending on the time of year.1. What does the passage mainly discuss?(A) observations of the stars by ancient people(B) rock formations of Arizona(C) a site used by ancient people to measure time(D) the movement of the earth around the Sun2.

Which of the following is NOT true of the spot of light?(A) It is caused by sunlight passing through a hole.(B) It travels across the roof of the shelter.(C) Its movement is affected by the position of the Sun.(D) It movement could have been used to estimate the time of day.7. From which of the following can be the time of year be determined?(A) The movement of the spot of light from west to east(B) The speed with which the spot of light moves(C) The movement of the spot of light from north to south(D) The size of the sport of light at midday8. The word "roughly粗糙地" in line 18 is closest in meaning to(A) finally(B) harshly(C) uneasily(D) approximately9. The passage mentions that the Hole in the Rock was used as all of the following EXCEPT(A) a calendar(B) a home(C) a clock(D) an observatory10. Which of the following can be inferred from the fourth paragraph?(A) The boulders are located below the rock shelter.(B) The person seated on the rock cannot see the shelter.(C) After it passes the boulders, the spot of light disappears.(D) The spot of light is largest when it first appears.答案：CABCA BCDBA。

Biological diversity has become widely recognized as a critical conservation issue only in the past two decades. The rapid destruction of the tropical rain forests, which are the ecosystems with the highest known species diversity on Earth, has awakened people to the importance and fragility of biological diversity. The high rate of species extinctions in these environments is jolting, but it is important to recognize the significance of biological diversity in all ecosystems. As the human population continues to expand, it will negatively affect one after another of Earth's ecosystems. In terrestrial ecosystems and in fringe marine ecosystems (such as wetlands), the most common problem is habitat destruction. In most situations, the result is irreversible. Now humans are beginning to destroy marine ecosystems through other types of activities, such as disposal and run off of poisonous waste; in less than two centuries, by significantly reducing the variety of species on Earth, they have unraveled cons of evolution and irrevocably redirected its course. Certainly, there have been periods in Earth's history when mass extinctions have occurred. The extinction of the dinosaurs was caused by some physical event, either climatic or cosmic. There have also been less dramatic extinctions, as when natural competition between species reached an extreme conclusion. Only .01 percent of the species that have lived on Earth have survived to the present, and it was largely chance that determined which species survived and which died out. However, nothing has ever equaled the magnitude and speed with which the human species is altering the physical and chemical world and demolishing the environment. In fact, there is wide agreement that it is the rate of change humans are inflicting, even more than the changes themselves, that will lead to biological devastation. Life on Earth has continually been in flux as slow physical and chemical changes have occurred on Earth, but life needs time to adapt — time for migration and genetic adaptation within existing species and time for the proliferation of new genetic material and new species that may be able to survive in new environments. 1. What does the passage mainly discuss? (A) The causes of the extinction of the dinosaur (B) The variety of species found in tropical rain forests. (C) The impact of human activities on Earth's ecosystems (D) The time required for species to adapt to new environments 2. The word "critical⾄关重要的" in line 1 is closest in meaning to (A) negative (B) essential (C) interesting (D) complicated 3. The word "jolting使震惊" in line 5 is closest in meaning to (A) predicted (B) shocking (C) unknown (D) illuminating 4. The author mentions the reduction of the variety of species on Earth in line 12 to suggest that (A) new habitats can be created for species (B) humans are often made ill by polluted water (C) some species have been made extinct by human activity (D) an understanding of evolution can prevent certain species from disappearing 5. The author mentions all of the following as examples of the effect of humans oil the world's ecosystems EXCEPT (A) destruction of the tropical rain forests (B) habitat destruction in wetlands (C) damage to marine ecosystems (D) the introduction of new varieties of plant species 6. The author mentions the extinction of the dinosaurs in the second paragraph to emphasize that (A) the cause of the dinosaurs extinction is unknown (B) Earth's climate has changed significantly since the dinosaurs' extinction, (C) not all mass extinctions have been caused by human activity (D) actions by humans could not stop the irreversible process of a species' extinction 7. The word "magnitude" in line 20 is closest in meaning to (A) concern (B) determination (C) carelessness (D) extent 8. According to the passage , natural evolutionary change is different from changes caused by humans in that changes caused by humans (A) are occurring ata much faster rate (B) are less devastating to most species (C) affect fewer ecosystems (D) are reversible 9. With which of the following statements would the author be most likely to agree? (A) Human influence on ecosystems should not be a factor in determining public policy. (B) The extinction of a few species is an acceptable consequence of human progress. (C) Technology will provide solutions to problems caused by the destruction of ecosystems. (D) Humans should be more conscious of the influence they have on ecosystems 答案： CBBCD CDAD。
