ThesisRefute the three explanations mentioned in reading passage. Sub-point1Kangaroo’s sharp and powerful claws would make deep marks during long trails. And if the footprints were left by the fleeing kangaroo, there must have been reports about this incident, but there wasn’t. Sub-point2There was a forest area in the way, and the hot air balloon would be entangled by tree branches and could not travel that long distance.Sub-point3The report was based on reliable materials. For one thing, there’s letter from Devin who found the footprints; For another thing, newspaper office collected a lot of details about the print. Thus the report wouldn’t be invented.

题目:太阳能吸收器放在太空有三个好处阅读: 1. 能够吸收更多能量

2. 能过避免彗星的冲撞 3. 能够对环境有好处

听力:

太阳能吸收器放在太空其实并没有什么好处1. 如果在太空的吸收器坏了。地面上要送一宇航员上去修理。这不仅非常花钱。而且,到达太空时间非常长。这一段吸收器不工作的时间,许多原本能被吸收的能量就浪费了。 2. 尽管彗星这种大的星体能够避免。但是太空中的space dust科学家时无法跟踪的。这些 dust 以非常高的速度运行,会给吸收器带来非常大的热量,从而造成损害。 3. 这些吸收器在太空吸收完能量后,会以 beam  ray 的形式把能量发回地面。 Beam  ray 会对大气层中的臭氧层造成损害,从而更多的紫外线会之间照射到人类、动物和植物。人类和动物会产生许多健康问题。植物的产量也会因此而减少。

1. 把那些把森林与森林之间隔开的农田变成森林走廊,这样森林之间就连上了。 2. 禁止非法捕猎,加大管理力度。 3. 囚禁(captivity)它们,人工饲养保护。

听力:

听力:并无多大效果 1. 猴狐生活之外的森林对于它们来说很危险,即便退耕造林建起连接的走廊,它们也不会走。 2. 不只有大量的人把狐猴抓起来做宠物,也会捕食它们,所以范围太大,方法多样,很难有效管控。

3. 狐猴的种类很多,习性不同,针对不同狐猴进行饲养可能有 20多种食物,这样可能很难保证饲养。

题目:

犀牛角非常的珍贵,以至于一些偷猎者不惜一切代价地猎杀犀牛,对犀牛的种群数量造成了严重的影响。为了保护犀牛,人们想出一种办法:把犀牛运到别的栖息地relocation plan ,防止偷猎者的捕杀。阅读和听力讨论这种relocation的方法是否有效。

阅读:

阅读:relocation对保护犀牛没有用。 1. 犀牛在relocation的过程中有2%-5%的死亡率。众所周知,犀牛是濒危物种,因此在运输过程中造成犀牛死亡,这中做法是不可取的。 2. 犀牛有着非常紧密的种族社会关系,如果把犀牛 relocate 的话,就会造成公犀牛和母犀牛的数量不平衡,会对犀牛的繁殖造成影响,此外它们的种族纽带也会被切断。 3. relocation不能完全防止偷猎者猎杀犀牛,因为犀牛角的价值很高,所以就算把犀牛运到别的地方偷猎者还是会紧随不放,所以不能从根本上解决问题。

听力:

听力: relocation可以很好地保护犀牛种群。 1. 虽然犀牛在运输途中不可避免地会发生伤亡,但是死亡的犀牛毕竟是少数。特别是把运输途中犀牛死亡率和盗猎者猎杀犀牛导致的死亡率对比时,会发现运输途中犀牛死亡数量远远低于盗猎者猎杀犀牛的数量。相比两种情况,还是 relocation好一些。 2. 阅读中所提到的犀牛性别不平衡问题在进行 relocation 之前就可以避免。保护者们会挑选一定数量的公犀牛和母犀牛,保持比例平衡。另外带着幼崽的母犀牛不会进行relocation,不会拆散它们的社会关系。 3. 把犀牛运到别的地方,那里地域广阔,犀牛有很大的活动空间,盗猎者在如此大的范围之内发现犀牛非常困难。另外,有些地方人很难通过,偷猎者无法到达。

3. Anting is a way for birds to feed on those ants.

听力:

Refute the three explanations mentioned in reading passage. 1. It is just a coincidence between the time of feather change and bird anting. 2. Anting cannot reduce the growth of parasites on some birds. 3. Birds will have other things to rub themselves, but they do not tend to eat those things.

讨论健康计划Wellness Programs(即公司推出奖励计划给达到healthy-related goal的员工是否对员工有益。

阅读:

Wellness Programs in United States bring lots of benefits to companies and employees. 1. The programs can become a motivational tool for people to lose weight and quit smoking, bringing much healthier lifestyle. 2. Employees will be more inclined to take exercises and have wholesome diets through the motivation of the Wellness Programs. 3. Although the program might cost companies a great deal of money at beginning, it saves more compared to the spending for employees’ sickness.

听力:

The program does not work. 1. The program may be an effective way to motivate employees in short term, but it cannot keep for a long period. Research shows that after several years, people are back to their bad habits. 2. The program is not fair for every employee, because cases differ. Some who have to take care of their family or cope with chores do not have enough time to exercise, while others are genetically fat. 3. Companies might suffer great financial loss in long term, because many employees will not stay in one company forever.

A kind of fish, the trout, was introduced to this area and the trout ate tadpoles of the frogs. 2. The use of pesticides contaminated the habitat. 3. The frogs there were infected by a fungal disease.

听力:

Refute the three explanations mentioned in reading passage. 1. The trout was introduced 100 years ago, however the decline happened 40 years ago. The time does not match. 2. Rainfall tends to wash the pesticides to lower and farther places. However, frogs lived in areas with higher altitude than that of farms using pesticides. 3. Yellow-legged mountain frogs can produce some antibodies within their bodies, so that they can resist to the infection of fungal disease.

听力:

Refute the three reasons mentioned in reading passage. 1. According to a research, there were still some connonballs in the gunspot, which proved that it cannot be opened. 2. Mary rose is flag ship. Sailors are all capable, so they will not fail to follow the captain’s lead under such dangerous situation. 3. Frenchmen told a lie in order to show that they were powerful than English.

题目:关于Pearl Poet是谁的三个假说。

阅读:

There are 3 possible hypotheses.1. John Massey might be possible, because he lived in northwestern England, where the poems came out, and the handwritings of John Massey and Pearl Poet are the same. 2. It might be Hugh, because he wrote poems about Garwin and those 4 famous handwritten poems are also related to Garwin. What’s more, the poems all adopt the rhetorical method of alliteration. 3. The 4 poems might not be written by one person because the poems referred different areas in England.

听力:

None of the 3 hypotheses is reasonable. 1. There was same copier in 14th century. That is why the handwritings are the same. 2. It cannot be Hugh because the dialect used in the poems of Pearl Poet and Hugh is totally different. 3. The poems cannot be made by several persons, because the wording of the 4 poems is very similar, which is impossible for different authors.

题目:关于降低风力发电涡轮对蝙蝠数量影响的方案。

阅读:

Three solutions can be used to lower the effect of wind turbines upon bats. 1. The wind turbines should be built in the areas far away from the migratory routes of the bats. 2. The wind turbines should be turned off in the night for bats are nocturnal. 3. Radars should be used to repel the bats, for the bats hate radar waves.

听力:

Those three solutions are not feasible. 1. The migratory routes of bats are exactly the places where wind turbines should be built, for if they are built in the remote areas, such as flat plain, the wind speed will decline.

2. Though the bats are not active in the daytime, they will choose sleep on tall structures, and the tops of the turbines are such places. 3. If bats meet the electromagnetic waves emitted by radars, those waves will prominently influence the reproductive systems of the bats.

阅读:

The writer puts forward three methods to address theproblem. 1. Use chemicals to destroy the polyp. 2. Harvest for human consumption 3. The government makes stricter regulation, letting workersclean the ballast water.

听力:

The measures are unconvincing. 1. The remains of polyp would breed the next generation quickly. Besides, using chemical ways might destroy other species in the marine or other places. 2. Only 12 kinds of jellyfish are edible. And people can only eat one percent of them. 3. Boat companies and fishmen will not be willing to do so, for it wastes a lot of time and has a negative influence on their economic profits.

题目:犀鸟(toucan bird)的巨大的鸟嘴的三种功能。

阅读:

3 reasons can explain why toucan evolved a bill. 1. Weapons against predators 2. Color and shape to hide from predator 3. Get rid of excess body heat

听力:

None of the 3 reasons about the bill’s function is reasonable. 1. It cannot function as weapons. It is made of hollow bones filled with air, so it is thin and lightweight or else it cannot fly. If it is used as a weapon,

2. They have to call out to each other in order to use the color and shape to blend into surrounding areas. If they do this, they are going to draw attention from predators. 3. Healthy toucan does not use their bills. They need bill to get rid of heat in the daytime but at night when the temperature is lower, they do not. They then need to retain body heat.

题目:考古学家Schliemann发现的金面具到底是不是真的。

阅读:

Heinrich Schliemann discovered a golden mask of warrior king. He claimed that the golden mask is the Mask of Agamemnon. However, the archaeology industry suspects that the golden mask is a fake. There are three reasons for that. 1. Firstly, Schliemann has a reputation of faking his discovery and excavation. He used to buy an antique from a craftsman and claim that the item is from ancient Greek until it was identified a fake. Therefore, the golden mask is very suspicious and Schliemann is incredible. 2. Secondly, some features of the golden mask are different from the authentic golden masks from Ancient Greek. Ancient Greek golden masks have very flat appearance and no pointed hairs. The golden mask of warrior king discovered by Schliemann has very well-defined lips and pointed beard. Therefore, the golden mask is a fake. 3. Thirdly, Schliemann immediately shut down the site where the golden mask is discovered after he found the golden mask. This is a very suspicious behavior. Usually archeologist will continue to excavate the site in the hope of finding more cultural information about the discovery, such as the historical context and identify whose mask it is. More information about the mask could have been discovered to identify the mask, however, Schliemann close the site in a rush, revealing his afraid of being found that the mask is a fake.

听力:

Though many archeologists think the golden mask of warrior king is a fake, but I think that is an authentic item from Ancient Greek. There are three reasons to refute the points in the passage.

1. Firstly, Schliemann did have a reputation of faking discovery and excavation. However, for this mask, it's not easy to fake. The Greek government is familiar with Schliemann's reputation of dishonesty and specifically assigned a supervisor to closely supervise and monitor Schliemann's work of excavation. If Schliemann really cheated on this discovery, it's hard to do so without being caught by the supervisor. 2. Secondly, a golden mask of lion from Ancient Greek, which was proved an authentic antique, was compared with the golden mask of warrior king. The golden lion mask also has three-dimensioned lips and nose, and all pointed hair. All the features are comparable to the golden mask of warrior king. 3. Thirdly, the timing of the site being shut down immediately after the golden mask was discovered can be explained. Schliemann was not a real archeologist but a treasure hunter. It fitted a treasure hunter's habit to close the site immediately after he depleted all the valuable things in the site. Therefore, Schliemann's behavior of shutting down the site is not suspicious.

题目: fort能不能起到防御作用

阅读:

一些考古学家认为公元前两千多年的forts 不能起到很好的防御作用 1. 不是所有的sides都有walls 所以很容易受到敌人攻击 2. multiple entranceways, enemies are easy to enter 3. no evidence of water and wells , 当被包围的时候很容易败

听力:

这些都是误解原因如下 1. 有些地方不用walls就可以起到防御的,比如有悬崖峭壁cliff 2. 敌人发现Spot之前就block封锁掉3. 可能是之前挖的井干了所以后人没看到不代表没有证据;不可能存在围攻的问题,因为敌人不会一直wait out

题目:防止蝙蝠白鼻综合征 (WNS)的方式。

阅读:

Suggestions to fight White Nose Syndrome (a kind of fungus killed lots of North American bats in the past few years) 1. One suggestion is restricting people to access the caves where bats live, because fungus can be spread cave to cave by riding on people’s clothes. 2. The second suggestion is studying a species of bats that is resistant to fungus. 3. The third suggestion is heating the cave.

听力:

Refute the three explanations mentioned in reading passage. 1. The lecturer refutes the point by saying that people are not main factors to help spread fungus, and it is bats themselves that spread the fungus, because in some caves where people cannot access, there’s fungus still. 2. Resistance is formed during the process of complex biological evolution. And understanding the process needs decades. However,the bats will die out in 10 years if there’s no effective remedy. 3. Bats die because the fungus wakes them up and forces them to face starvation. If the caves are heated, bats will be unable to sleep and thus suffer the starvation.Therefore this suggestion will make the situation worse.

听力:

The listening argues against the three reasons mentioned in the reading. 1. Infertility can be cured by regulating the rhino’s hormone. 2. Advanced radiographic image equipment can detect the early anomaly of the bone and feet, which can heal the foot disease. 3. The reason for the little rhino’s brain disorder is that its mother is so old that it carries toxic chemical element. So letting younger rhino bear child is one of the solution.

题目:电子病历的三个优点。

阅读:

在美国,某些人认为电子病历有三个优点。 1. 省钱,不会发生错误,和利于做科研。 2. 电子病例是用电脑写的,因此辨识度很高,不容易错。 3. 电子病历利于更方便的取得大量病人的相关资料做研究。

听力:

1. 教授认为这些优点是不确定的,他说,即使有了电子病历,医生们还是会把纸质病历作为备份,所以存储转移这些病历的费用并没有省下来。 2. 虽然电子病历使用电脑,但是还是难免出现错误,因为病历还是由医生手写,职员打字输入的,在辨识医生的文字和输入电脑的过程中都有可能出现错误。 3. 教授说在美国病人的病历属于隐私的范畴,有隐私法来监督,研究人员不可能随意的查看病人的病历,首先他必须经过严格复杂的程序获得很多人包括病人自己的允许才能查看病历,所以关于电子病历的这个优点是不存在的。

听力:

1. Company has limited time to finish this work. Workers are under time pressure and it is reasonable that they are careless and apply lead to the cans in a hurry way. 2. First, it is difficult to judge whether sailors are affected by lead without careful tests. Second, the symptoms of lead poisoning are common, such as feeling tired or headache and they can be easily overlooked. 3. The water in the purification system is used for ship engineering since the salt water cannot be used. The water for cooking and drinking comes from a different way.

阅读:

saber-toothed cat是群居动物。 1. Fossils of saber-toothed cats with broken bones indicate that they were fed by other saber-toothed cats when they were injured 2. There are large numbers of saber-toothed cats in the trap. The saber-toothed cats hunted together. The sound of dears in the trap attracted them to fall in the trap together 3. Saber-toothed cats lived with other predators such as lions and wolves. Saber-toothed cats have to live in group to compete with those predators.

听力:

剑齿猫不是群居动物。 1. The fossils of saber-toothed cats with broken bones indeed indicate that they could survive when they were injured. However it doesn’t necessarily mean that they have to be fed by other saber-toothed cats. Many predators can find dead animals to eat. So did the saber-toothed cats 2. The large numbers of saber-toothed cats in the trap doesn’t mean that they hunt together. The saber-toothed cats hunt separately. One of the saber-toothed cats heard the sound of the trapped dear, went to the trap and fell. Then another saber-toothed cat also heard the sound of the trapped dear, came to the trap and fell again 3. Saber-toothed cats were large predators. Take tigers for example, one tiger is strong enough to fight against the social predators such as lions and wolves. So the saber-toothed cats don’t have to live together to compete with lions and wolves.

阅读:

有三个理论。 1. 第一个理论:有助于保温。 2. 第二个理论:防止真菌感染,不让雨水进去。 3. 第三个理论:避免接受月光,以此跟随季节变化。

听力:

反驳三个理论。 1. 第一个理论:没有帮助。因为植物没有internal heat,在遇到冷的天气,尤其是冰点以下时不能避免冻害。 2. 第二个理论:下雨时即使叶子闭合,也会有少量雨水进入,而真菌只需要少量的雨水即可,因此是没有意义的。 3. 第三个理论:举一个反例。在一些denser的森林中,有些植物即便在树荫下接收不到月光,也会闭合叶子。因此需要其他的解释。

题目: Arizona发现一个2亿年前的虫子的巢化石是不是蜂巢。

阅读:

很多人认为这是蜂巢,但这是不可信的。 1. 2亿年前还没有蜜蜂,哪里来的蜂巢; 2. 2亿年前连flowering plants都没有,怎么会有需要吃花蜜的蜜蜂; 3. 现代蜜蜂的巢都有个盖子 cap,那个化石没有,所以这个巢很可能是其他虫子的。

听力:

反对,这个化石是蜂巢。 1. 没有发现有200百万年前的蜜蜂化石不代表没有200百万年前的蜜蜂,那时候蜜蜂筑巢的树比较难留下来,所以没有化石也正常。 2. 古时候的蜜蜂就一定要吃花蜜吗?他们不能吃nonflowering plants吗? 3. 没有盖子cap可能因为化学原因,腐蚀掉了什么的,再说为什么要跟modern bee一样呢?

题目:

Whether the declining of bison was caused by the European American settlers.

阅读:

About bison, a kind of animal, something like cattle or horse. The passage suggests that the declining bison was due to the European American settlers: 1. When European American cross prairies, they hunted bison as food

because there is no food in prairies.2. They brought cattle and horses, which competed with bison for resources.3. The evolving technology, especially guns, let hunters kill several bison in a short time.

听力:

The professor contradicts each of these three points: 1. The European American moved from east to west, but the bison decline in the western part of America. The pattern of how bison disappeared gradually was different from that of movement of European American.2. Bison have double furs covering their bodies and unique head structure, which allow them to live in harsher and colder areas. The areas were unreachable for cattle and horses. How could different spices compete with each other in separate territories?3. The advanced technology should not be blame worthy for the decreasing bison. The ancient methods are as effectively as guts. Skilled ancient American hunters could kill several bison with short intervals.

题目:

两种哺乳动物:有袋动物和无袋动物。有袋动物是否比无袋动物更原始,发育不完全,缺乏竞争力。

阅读:

有袋动物marsupials比无袋动物placental更原始。 1. 第一因为幼崽在母亲的袋子里生活使得发育不完全,免疫能力差。 2. 第二它们对温度的控制能力差。 3. 第三在澳洲有袋动物占多数因为没有太多无袋动物,而其他地方有袋和无袋生活在一起有竞争,所以说有袋竞争不过无袋动物。

听力:

听力反驳。 1. 第一有袋幼崽其实发育的很好,它们喝奶的时候同时也从奶中获得了抗体因此免疫好。 2. 第二有袋动物体温会变是为了适应环境,比如降低体温来减少能量消耗。 3. 第三很久以前在澳洲有袋和无袋一起生活的,而后来有袋占多数说明无袋竞争不过有袋。

题目:讨论wetland里面的鬼火( will-o'-the-wisp)形成的原因是什么。

阅读:

3个可能的原因。 1. Protection against cold (losing heat). 2. Protection against fungal spores infection, block out water so insects have meanings of fungal infection. 3. Eliminate night time light, in order to track up to the regular time to produce flowers.

听力:

1. The plants have no source of internal heating, so whether folding or unfolding suffer the same freezing damage. 2. Even though the plants are folding, they cannot block out all the water and fungal spores only require a few water. 3. Some plants in densely shaded area where no light is reaching still fold their leaves, therefore some other reasons may explain.

题目:讨论是在北美发现的土堆(Mima Mound)形成的原因是什么。

阅读:

Three theories to explain how the Mima Mound is formed. 1. Mima Mounds were formed by human labor because they were arranged in order. 2. Mima Mounds were caused by earthquake.After shaking, the land becomes loose and reshape to the Mima Mound. 3. Build by pocket gopher to build nest.

听力:

These three theories are all unconvincing at all. 1. It cannot be created by human labor because there are no human activities and remains to support the theory. 2. Earthquake is impossible to take place in where Mima Mound existed. Besides, there were no enough earthquake to loosen the soil.

3. There are gophers nowadays, but no new Mima Mounds have been found.

题目:威胁Inuktitut加拿大语言的三个要素

阅读:

Inuktitut这种语言是在加拿大一部分地区被人使用的语言,由于说这种语言的人很少,政府采取措施保护这种语言,但是很多人认为威胁这个语言的还有一些其他因素,列举的三个威胁Inuktitut语言的因素如下: 1. 调查表明,当地有少于25%16岁以下的人说这种语言,如果如此少的年轻人说这个语言的话,那么它传承下去的可能性比较小。 2. 当地很多的家长是渔民,需要用英语做生意,很多家长意识到了英语的重要性,于是让孩子学习英语,这个也会威胁Inuktitut语。 3. 电视和其他的媒体方式对孩子的影响比较大,但是当地 Inuktitut 语言的电视节目比较少,且最近还关掉了两个Inuktitut语言的节目。

听力:

并没有这么多的其他因素可以影响到Inuktitut语言的使用情况。 1. 调查的数据不准确,另一批研究人们研究表明,当地说Inuktitut语言的人并不是低于25%,只是说传统的Inuktitut语言的人比较少,大部分的人都是在使用现代版的Inuktitut语言。 2. 很多家长在意识到英语的重要性之后,让孩子说两种语言,及英语和Inuktitut 语言都使用。 3. 再一次的调查研究表明Inuktitut 语言节目在当地不论是电视还是电台都有 strong appearance,并不像文章中说的那样。
