TPO49综合写作

阅读文本：

Like many creatures, humpback whales migrate long distances for feeding and

mating purposes. How animals manage to migrate long distances is often puzzling.

In the case of humpback whales, we may have found the answer: they may be

navigating by the stars, much as early human sailors did. What we know about

humpback whales makes this a distinct possibility.

First, humpback whales seem to be intelligent enough to use stars to

navigate by. Whales' brains have a high degree of complexity--a common

determiner of intelligence. This suggests that the whales' brain power far

exceeds that of most other animals. The whales' well-developed cognitive ability

seems to provide a sound basis for the ability to use a complex, abstract system

of sensory stimuli such as the night sky for orientation.

Second, humpback whales migrate in straight lines. Animals can maintain

movement in a straight direction for long distances only if they orient

themselves by some external objects or forces. Many birds and other terrestrial

creatures, for example, use physical landmarks to help them stay on track as

they migrate. Whales, which swim in the open ocean, cannot rely on land

features; they could, however, rely on stars at night to provide them with

external signs by which to maintain direction over long distances.

Third, humpback whales exhibit an unusual behavior: they are sometimes

observed floating straight up for minutes at a time, their heads above the water

as though they were looking upward. The behavior is known as spy-hopping, and it is very rare among marine animals. One explanation for the function of

spy-hopping is that the whales are looking at the stars, which are providing them with information to navigate by.

Professor:

The theory that humpback whales use the stars to navigate the open seas is

a fascinating one, but the evidence supporting the theory is not very convincing.

First, there doesn’t seem to be any real connection between intelligence

and an animal's ability to use stars for navigation. You know, there are other animals that use stars to navigate. Some birds have this ability, like ducks for example. Now the general cognitive ability of ducks is only average. They are not highly intelligent. The fact that the ducks evolved the ability to use stars for navigation does not seem to have much of a connection to their overall intelligence. It's just an instinct they were born with, not a sign of intelligence. So the fact that humpback whales happen to be intelligent does not make them particularly likely to use stars for navigation. The two things just don't seem to be connected.

Second, there may be a different explanation for the humpback whale’s

ability to navigate in straight lines. Remember that for animals to be able to do this, they have to sense some external object or force. Well, the external force the whales could be sensing is Earth’s magnetic field. Humpback whales have a substance in their brains called biomagnetite. Generally, the presence of

Many people believed the coin had been originally brought to North America by European explorers known as the Norse, who traveled across the Atlantic Ocean and came into contact with Native Americans almost a thousand years ago. However, some archaeologists believe that the coin is not a genuine piece of historical evidence but a historical fake; they think that the coin was placed at the site recently by someone who wanted to mislead the public. There are three main reasons why some archaeologists believe that the coin is not genuine historical evidence. Great Distance from Norse Settlements First, the Native American site in Maine where the coin was discovered is located very far from other sites documenting a Norse presence in North America. Remains of Norse settlements have been discovered in far eastern Canada. The distance between the Maine site and the Norse settlements in Canada is more than a thousand kilometers, suggesting the coin has no real connection with the settlements. No Other Coins Found A second problem is that no other coins have been found at the Canadian sites that were inhabited by the Norse. This suggests that the Norse did not bring any silver coins with them to their North American settlements. Third, the Norse who traveled to North America would have understood that silver coins would most likely be useless to them. Silver coins may have been in wide use in Europe at the time, but the Norse, as experienced explorers, would have known that native North Americans did not recognize silver coins as money. 托福TPO44综合写作听力原文文本： Professor: Actually many archaeologists believe that the coin discussed in the reading is not a fake. They believe it represents genuine evidence that the Norse came into contact with Native Americans a thousand years ago. First, the great distance of the Maine site from the Norse settlements in Canada. Well, many other objects found at that same Native American site had come from faraway places. Not just the coin. There's a perfectly reasonable historical explanation for these objects. The Native Americans who lived at the Maine site traveled great distances within North America. They were interested in obtaining objects from faraway places. The Native Americans could have reached the Norse settlements during their travels and brought the silver coin back to Maine. Second, does the fact that we found no other coins at Norse settlements mean that the Norse didn't bring any coins with them? Not necessarily. The Norse didn't create permanent settlements in North America. At some point, they went back to Europe. When

托福OG综合写作题目(1-3套)

托福OG综合写作题目（1-3套） 智课出品 TEST1 Altruism is a type of behavior in which an animal sacrifices its own interest for that of another animal or group of animals. Altruism is the opposite of selfishness; individuals performing altruistic acts gain nothing for themselves. Examples of altruism abound, both among humans and among other mammals. Unselfish acts among humans range from the sharing of food with strangers to the donation of body organs to family members, and even to strangers. Such acts are altruistic in that they benefit another, yet provide little reward to the one performing the act. In fact, many species of animals appear willing to sacrifice food, or even their life, to assist other members of their group. The meerkat, which is a mammal that dwells in burrows in grassland areas of Africa, is often cited as an example. In groups of meerkats, an individual acts as a sentinel, standing guard and looking out for predators while the others hunt for food or eat food they have obtained. If the sentinel meerkat sees a predator such as a hawk approaching the group, it gives an alarm cry alerting the other meerkats to run and seek shelter. By standing guard, the sentinel meerkat gains nothing—it goes without food while the others eat, and it places itself in grave danger. After it issues an alarm, it has to flee alone, which might make it more at risk to a predator, since animals in groups are often able to work together to fend off a predator. So the altruistic sentinel behavior helps ensure the survival of other members of the meerkat’s group. Summarize the points made in the lecture, being sure to explain how they oppose specific points made in the reading passage. TEST2 Professors are normally found in university classrooms, offices, and libraries doing research and lecturing to their students. More and more, however, they also appear as guests on television news programs, giving expert commentary on the latest events in the world. These television appearances are of great benefit to the professors themselves as well as to their universities and the general public. Professors benefit from appearing on television because by doing so they acquire reputations as authorities in their academic fields among a much wider audience than they have on campus. If a professor publishes views in an academic journal, only other scholars will learn about and appreciate those views. But when a professor appears on TV, thousands of people outside the narrow academic community become aware of the professor’s ideas. So when profes sors share their ideas with a television audience, the professors’ importance as scholars is enhanced. Universities also benefit from such appearances. The universities receive positive publicity

TPO17 综合写作 听力文本

Listening The passage clams that there will be fewer and fewer birds, but the arguments used to support this claim are unconvincing. First, it’s true that urban growth has been bad for some types of birds, but urban development actually provides better and larger habitats for other types, so much so that city and suburban dwellers often complain about increased birds populations—seagulls at landfills, pigeons on the streets and so on. Even birds like hawks and falcons can now be found in cities, where they prey on the increasing populations of pigeons and rodents. So it’s not going to be a story of uniform decline of bird populations in the future. Some populations may shrink, but others will grow. As for agriculture, it’s true that it too will increase in the future, but not in the way assumed by the reading passage. The truth is, in the United States, less and less land is being used for agriculture every year. Increasing in agricultural production have resulted from and will continue to result from the introduction of new, more productive varieties of crops. These new crops produce more food per unit of land, and as a result, there’s no need to destroy wilderness areas. And third, while it’s certainly true that traditional pesticides have been destruct ive to birds, it’s incorrect to project this history into the future. Now that people are aware of the possible consequences of traditional pesticides, two changes have occurred. First, new and much less toxic pesticides have been developed, and that’s imp ortant. Second, and perhaps more importantly there is a growing trend to develop more pest resistant crops, crops that are genetically designed to be unattractive to pests. Pest resistant crops greatly reduce the need for chemical pesticides. And best of all, pest resistant crops don’t harm birds at all.

Because they often cannot distinguish between glass and open air, millions of birds are harmed every year when they try to fly through glass windows. There are, however, several solutions that responsible businesses can use to prevent injuries to birds. One-Way Glass One solution is to replace the regular, clear glass with one-way glass that is transparent in only one direction.

Professor: OK. We’ve been talking till now about the two basic needs of a biological community – an energy source to produce organic materials, you know uh, food for the organisms, and the waste recycling or breakdown of materials back into inorganic molecules, and about how all this requires photosynthesis when green plants or microbes convert sunlight into energy, and also requires microorganisms, bacteria, to secrete chemicals that break down or recycle the organic material to complete the cycle. So, now we are done with this chapter of the textbook, we can just review for the weekly quiz and move on to the next chapter, right? Well, not so fast. First, I ‘d like to talk about some discoveries that have challenged one of these fundamental assumptions about what you need in order to have a biological community. And, well, there actually were quite a few surprises. It all began in 1977 with the exploration of hydrothermal vents on the ocean floor. Hydrothermal vents are cracks in the Earth’s surface that occur, well, the ones we are taiking about here are found deep at the bottom of the ocean. And these vents

Glass is a favored building material for modern architecture, yet it is also very dangerous for wild birds. Because they often cannot distinguish between glass and open air, millions of birds are harmed every year when they try to fly through glass windows. There are, however, several solutions that responsible businesses can use to prevent injuries to birds. One-Way Glass One solution is to replace the regular, clear glass with one-way glass that is transparent in only one direction. The occupants of the building can see out, but birds and others cannot see in. If birds cannot see through a window, they will understand that the glass forms a solid barrier and will not try to fly through it. Colorful Designs A second solution is to paint colorful lines or other designs on regular window glass. For example, a window could have a design of thin stripes painted over the glass. People would still be able to see through the openings in the design where there is no paint, while birds would see the stripes and thus avoid trying to fly through the glass. Architects can be encouraged to include colorful painted patterns on glass as part of the general design of buildings. Magnetic Field The third solution is to create an artificial magnetic field to guide birds away from buildings. Humans use an instrument called a magnetic compass to determine directions—either north, south, east, or west. Bird research has shown that birds have a natural ability to sense Earth’s magnetic fields; this ability works just like a compass, and it helps birds navigate in the right direction when they fly. A building in a bird flight path can be equipped with powerful electromagnets that emit magnetic signals that steer birds in a direction away from the building. Now liste n to part of a lecture on the topic you’ve just read about. None of the solutions you’ve read about will effectively stop birds from getting injured. First, replacing regular glass with one-way glass. Well, the problem with one-way glass is that to the bird on the outside, a one-way glass surface reflects just like a mirror. And a surface that reflects like a mirror is just as bad as regular glass for birds because birds don’t understand mirrors. If they see a reflection of the sky in a mirror or of a tree in the mirror, they think the reflection is the sky or is the tree and they’ll fly right into them. The second solution, painting colorful patterns like stripes on regular glass, also has problems. As the reading said, these designs include openings so people inside the buildings can see out. But birds will perceive these unpainted openings as open holes. And if birds think they’re seeing holes, they will try to fly right through them. To prevent birds from doing this, the unpainted spaces in the window would have to be extremely small. But that would then make the rooms of the buildings too dark for the people inside them. The third solution, creating an artificial magnetic field, won’t work very well, either. While it’s true that birds use Earth’s magn etic field to help them navigate, they use this only when they’re traveling very long distances. For example, if a bird is migrating from a cold country to a warm one during winter, it will use its magnetic sense to figure out which way it should fly. But this ability isn’t used to go over short distances such as going from one side to the city to another.

TPO20综合写作范文

The reading passage explores the topic of the “Let it burn” policy. The professor’s lecture deals with the same issue. However, she thinks that the “Let it burn”policy is fundamental positive policy, which contradicts what the reading states. And in the lecture, she uses three specific points to support her idea. First, the professor argues in the lecture that the fire enhanced the diversity of vegetation in Yellowstone Park, even though the reading passage suggests that Yellowstone fires caused tremendous damage to the park's trees and other vegetation. This is because that the fire has created a opportunity for some new plants to grow, for instance, the small plants which needed open un-shaded area and the seeds which demanded high levels of heat to germinate, which means that the small vegetations would had a better environment after the large trees had been destroyed. Obviously, the professor's argument disproves its counterpart in the reading. Moreover, despite the statement in the reading that the park wildlife was affected, and there was also concern that the destruction of habitats and food chains, the professor states that the fire also created new opportunities for some animals’ thriving that the population could recover and strengthened certain food chains. Then he supports this point with the fact that, for example, the new plants offered perfect habitats for some animals like rabbits and hares, and promote their predators’ booming the

However, dinosaurs differ in many ways from modem reptiles, and there is now considerable evidence that dinosaurs were, in fact, endotherms.
