第一套6-1Sample AnswerMany monkeys live in the top parts of forest trees and have no access to underground water but they are still able tosurvive. This is because they secure water supply from either food or rain. In the lecture, the first example shows howhowler monkeys get water from their food. The majority of their diet is composed of tender leaves and they are able toabsorb sufficient moisture from those leaves. The second example is how spider monkeys collect rainwater. Spidermonkeys are able to use a cup-like plant as a container and link these cups to the trees in the forest. As the cups arefilled with rainwater they drink directly from the cups. These examples tell us that monkeys have their own way ofgetting water and do not need to live close to water sources in order to survive.第一套6-2Sample AnswerIn this lecture the professor talks about social cooperation among a group of animals in fact increases the efficiency offeeding. There are two methods for cooperation: one is through feeding in groups and the other is throughcommunication. In the first example, a group of deer are able to feed themselves more quickly because some of themcan watch for predators while the others eat without distraction. In the second example, a honeybee communicates thelocation and distance of a food source to others by doing the waggle dance, As a result honey bees are able to feedthemselves more efficiently by sharing information with others. Both examples illustrate the fact that socialcooperation can sometimes benefit animals' feeding and animals don't always need to fight against each other for food第二套第一个Sample AnswerIn the lecture the professor talks about how some aquatic organisms are able to remain near their habitats without beingcarried away by rapid ocean currents. Two methods of doing so are attachment and sinking. The first example is theblack fly larvae, which make silky pads with their mouths on the surface of rocks or vegetations and use ananchor-shaped hook on their stomach to attach themselves to the surface. That way they don't get blown away bystrong water currents. The other example is the sculpins. They're different from most other fish because they don'thave a swim bladder. Without a swim bladder, they can't float in the water and when fast currents hit, they sink in thewater instead and don't move along with the ocean currents.第二套第二个Sample AnswerCarbon dioxide is the byproduct of manufacturing. It can transmit sunlight but also prevent radiation from going backinto space, which causes the greenhouse effect and increases temperature on Earth's surface. The professor mentionstwo methods to control carbon dioxide before it's released to the atmosphere, including carbon capture system and treesequestration. One is by direct processing of carbon dioxide within the factory and depositing the captured carbon at astorage site. The other method is to plant sufficient trees outside of the factory because trees by nature are able toabsorb carbon dioxide from the air into their leaves. It is more effective to capture carbon dioxide at the source pointthan from the air, which means the results of capturing carbon dioxide within the factory would be more remarkable.第三套Sample AnswerPaleodiet is the study of different types of food human beings used to eat in the past. As most people didn't keep awritten record of what they ate so archeologists often use two methods to find out human's diet in the history, such asstudying paintings from the past and fossils of food remains. The first example is that Romans painted fruits to showtheir wealth and hospitality and Egyptians drew their food on the walls of the pyramids. Another way archeologists useto study paleodiet is through food remains. They study the fossils of seeds and plants from archeological sites tounderstand how vegetables, fruits and grains played a role in human's diet in the eighteenth century.第四套Sample AnswerWildlife conservation is the practice to protect endangered animals, plants, and their habitats. As we enjoy hiking, weare also posing threats to species living on our hiking paths. The professor discussed two methods to protect thewildlife from being damaged by tourists' recreational nature walks. The first is to build hiking trails so that tourists canonly wall along the trail and not all over the forests. This can prevent the wildlife from being disturbed. The secondmethod is to limit the number of visitors per day and assign tour guides to small groups of tourists. Tour guides will beable to lead the hikers onto a specific path and make sure no one is causing damages to the wildlife.第五套Sample AnswerCrop rotation is a common practice in agriculture to grow different crops in the same area every growing season. Theprofessor in the lecture talks about two advantages that crop rotation brings, including restoring nutrients in the soilandpest control. First, the alternative crop is able to restore nutrients exhausted by the other crop in the soil so the landis capable of continuous production. For example, wheat consumes most nitrogen in the soil while beans restorenitrogen in the following season. The other benefit is to control insect pests. Wheat pests are only attracted to wheatand do not use beans as a food source. Therefore by growing beans in the following season the life cycle of wheat pestscan be broken and the number of insect pests can be reduced.第六套Sample AnswerThe professor talks about two characteristics found in successful people's goal setting, including being specific andrealistic about their goals. For example, if someone wants to buy a car within one year, he or she is more likely toaccomplish the goal if they include specific information about the car in their goal, such as the model of the car and theprice of the car. The other characteristic is being realistic about their goals. For instance, if someone sets a goal to reada hundred pages in a textbook within one night, that would be an unrealistic goal and of course the person won't beable to accomplish it. Ifthe goal is to read a hundred pages within a week, the person is more likely to succeed inachieving this goal.第七套Sample AnswerIn the lecture the professor talks about some unusual parenting behaviors in mammals that can be mistaken asprevent getting attention from their predators, which in fact increases the babies' safety. The first example is how themother deer hides her babies alone in the woods or meadows while they feed or sleep. The other example is the rabbits. Mother rabbits are able to produce highly nutritious milk so that their babies need to be fed only once per day andmother rabbits barely go back to their nests when parenting. Both examples are contra~ to humans' idea of parentingbut they are actually crucial survival strategies for these animals.第八套Sample AnswerThe marine biology professor talks about two methods of how marine mammals keep themselves warm in water, suchas developing certain physical features and behavioral adaptations. Marine mammals are warm-blooded and watermakes them lose heat more easily than in the air. This makes maintaining their body temperature while in water achallenge for them. First they have developed some physical features to keep themselves warm, including a thick layerof blubber and fur skin. Seals, for example, possess both layers of fat and furry skin in order to insulate their bodiesfrom external coldness. Marine mammals also conserve body heat throughbehavioral adaptation. Marine mammalsconsume a lot of food because digestion is able to create heat for them. Sea otters are one example.第九套Sample AnswerIn the lecture, the professor talks about how lobsters have developed physically to adapt to the dark water environmentsuch as compound eyes and antennae that produce low frequency vibration. First, within their compound eyes, therecan be as many as ten thousand lenses that can be used to detect motion in the water and capture dim lights under thesea. This helps them spot their predators in the dark water. The other organ they have developed is their antennae. Theyantennae are able to produce a low frequency vibration like a buzzing sound to escape danger or to warn others ofdanger. For example, if a predator is trying to eat the lobster, the buzzing sound will either scare the fish away or signalother lobsters to move to safer places.第十套Sample AnswerIn this lecture the professor talks about how forest fires are in fact able to help animals survive rather than destroythem such as exposing prey animals and burning; away toxins, First, forest fires can expose some prey animals in openareas so their predators can spot them more easily. For example, during forest fires, turkeys usually wait on the edge ofthe forest to capture worms that are trying to escape from the fires. The other way that forest fires benefit animals is bymaking the environment more habitable. For example, beetles usually can't live in XYZ trees because those treescontain poison in their bark. However, after the fires burn away the bark beetles can lay eggs in these trees and nurse their larvae there.第十一套Sample AnswerIn the lecture, the professor talks about what predatory animals do to prey on animals traveling in groups such asidentifying unique members of the groups or breaking up the groups. Animals travel in groups in order to scare theirpredators and make it difficult for the predators to locate the individuals. However, scientists found fish of differentcolors from those of other members in the ABC fish community are more likely to be preyed on because theirpredators can identify the unique individuals. Other predators would break up the groups in which animals aretraveling to make it easier to locate individuals. For instance, sharks would swim into fish crowds and wave its tailquickly to break the crowds into smaller groups or even individuals so the sharks can locate the fish more easily.第十二套Sample AnswerIn the lecture the professor talks about two physical features cheetahs have developed to adapt to living in adverseenvironments such as their feet pads and muscular long legs. First, cheetahs have grown pads underneath their feet toprotect themselves from the high temperature in deserts or rough surfaces of other places they live. This allows them totravel at a high speed without being slowed down by geographic factors. The other feature is cheetahs' muscular longlegs. Cheetahs' back legs are capable of providing cheetahs with a powerful force that sends their body forward as theytravel. In addition, as their legs are particularly long, they are able to travel a long distance within a short amount oftime. For these adaptive features, cheetahs can thrive and sprint in different unfavorable environments.。
