Lecture:浪漫主义诗歌主要讲了18-19 世纪英国浪漫主义(Romanticism)诗歌的代表人Wardsworth的诗。
他是浪漫主义的鼻祖,但浪漫主义这个称谓是后人加上的,不是他们本身这样称呼自己的(此处出题)。
浪漫主义不是我们平时理解的浪漫,和男女之间的爱情无关。
浪漫主义针对的是普通人而不是少数受过教育的人,用的是简单语言,描述的是日常生活中常见的事物,孩子,人类情感,以及自然和人类之间的互动。

--泰戈尔神经元细胞(四道题)来源: 太傻网考试频道整理时间: 2008年07月04日lecture神经胶质细胞研究。
教授说早期对人类大脑的研究集中在神经细胞neuron,让一男生起来回答上节课的主要内容,男生说生物电生物电bioelectricity 通过神经细胞传导,通过两个神经细胞的接触点传到下一个细胞,有趣的是。
说到这里被教授打断,说他答得已经很完整了(有题,问教授打断他的用意)。
神经胶质细胞glial cells的作用在早期被忽视了,人们认为胶质细胞只有支持神经细胞的作用。
后来人们发现胶质细胞也有传导信息的作用,不是通过生物电,而是化学物质传导。
于是总共有三种传导方式,神经细胞间,胶质细胞间,神经和胶质细胞互相传导。
而且发现胶质细胞的数量及其巨大,远多于神经细胞。
同时还可能有修复神经细胞,决定哪些神经长的大[记得可能不准]。
教授又说,胶质细胞可能与智力有关,越多智商越高,但这不确定。
教授说对胶质细胞的研究是一个很open up的领域,建议学生们可以考虑毕业后作深入研究(有题)。
重要:biology 讲glial cell。
以往人们对神经传导的研究仅限于neuron(神经元),也叫nerve cell。
神经传导通过electrical communication从一个结点传到另一个结点,神经元被认为起主要作用,glial cell研究的很少,一直被忽略,被看作help the growth of neurons (出题),起辅助作用。
后来偶然发现大脑中glial cell比neuron的数目多很多,glial cell引起了科学家的重视,开始研究它究竟起什么作用(此处出题,问glial cell怎么引起科学家注意的)。
后来有一重大突破,发现glial cell传导信号不是用的electrical signal,而是用chemical conductor(一说chemical communication)(此处出题)。
托福听力加试大王花Rafflesia原文及试题答案RafflesiaListen to part of a lecture in a Botany classP: We've been talking about plant classifications and how species belong to a family and families belong to an order, but sometimes, figuring out how we assign certain plant species to a particular order is challenging, even if the plant has...unusual characteristics. You'd think that plants with similar characteristics would belong to the same order, but that's not always true. A good example of this is a flower, that is—a flowering plant—that grows only in Malaysia and Indonesia, called Rafflesia.As you can see, Rafflesia is a pretty unusual plant. For starters, it's huge. The flower can grow up to a meter in width and can weigh up to seven kilos—pretty big, huh There aren't any other specimens in the plant world that have flowers even close to this size. But that's not the only unusual characteristic of Rafflesia, in fact, that's probably one of the least strange features of the plant.The plant also emits a terrible stench, like rotting meat. But again, there are other plants with bad smelling flowers. And in the case of Rafflesia, flies are attracted to that smell, and that's how the flowers get pollinated. So...um...Rafflesia's flowers are huge and smelly. Rafflesia is also a parasite; it gets its energy from another plant instead of from the sun, which is unusual, but not unheard of in the plant kingdom. It actually grows inside its host, which is a type of grapevine. I mean... it grows inside its host until it blooms—it doesn't bloom inside the host. But that leads me to...I want to tell you really quickly about another plant, a plant that's also from the forests of Southeast Asia, called Mitrastema.Now, Mitrastema is also a parasite, which led some to believe that Rafflesia was related to Mitrastema—that they belong to the same order. Mitrastema as I said is a parasite, but its flowers are much smaller, and don't smell bad, so you can see why there was debate about whether they were related. But as it turns out, Mitrastema is actually related to blueberries. So, even plants that share an unusual characteristic with Rafflesia are not related to it. And, um...no plant shares all three of its unusual characteristics, and that made classifying Rafflesia very, very difficult.Now, you're probably thinking, why don't they just analyze the DNA of the plant Well, as I said, Rafflesia is a parasite. It lacks the leaves; the green tissue that most plants need for photosynthesis. It's unable to...um...to capture the sunlight most other plants use to make food. So, it's lacking...it...it...it doesn't have the DNA—the genes—for photosynthesis, which is what we usually use to classify plant species. But some researchers in Michigan persisted, and analyzed about 90 species of seed plants and compared them to Rafflesia, and we finally had an answer. Rafflesia was part of the Malpighiales order.Now, other species in the Malpighiales order includeviolets...um...poinsettias...uh...passion-flowers...what else Willows. So it was pretty unexpected because flowers like violets are a lot smaller than Rafflesia, right And they don't smell bad—they don't smell like rotting meat...and they're not parasitic. It took almost 200 years to classify Rafflesia, to identify its relatives, and I don't think anyone would have ever guessed that it's in the order Malpighiales. I mean...you know-it'd be nice to be able to classify species based on their obvious characteristics, but, it didn't work that way with Rafflesia. And unfortunately for Rafflesia, and for the field of botany, it seems that Rafflesia may be dying out. It's certainly endangered because of deforestation in its habitat. And to make matters worse, Rafflesia doesn't reproduce very well. First of all, only 10-20% of buds turn intofull-fledged flowers, and it can take them a year to grow. There are also male flowers and female flowers, and one of each has to be in the same area—the same vicinity—at the same time, to produce seeds, and the flies that are attracted to the flower's strong smell have to carry pollen from one flower to the other, so how often do you think these events occur all together Even people who study the plant for years may never witness it.考题:问题一:主旨题What is the lecture mainly about正确答案:(C) 植物的分类困难。
新托福iBT听力经典加试:浪漫主义诗歌(试题及答案)英国浪漫主义诗人华兹华斯及其诗歌18-19 世纪英国浪漫主义(Romanticism) 诗歌的鼻祖华兹华斯Wordsworth 的诗歌。
浪漫主义这个称谓是后人加上的,不是浪漫主义诗人对自己的称呼(此处有题)。
浪漫主义Romanticism 不是我们平时理解的浪漫romance/romantic,和男女之间的爱情无关。
Romanticism针对的是普通人common people 而不是少数受过教育的人educated people。
浪漫主义诗人用简单的语言simple language 描述日常生活中常见的事物、孩子、人类情感以及自然和人类之间的互动(有题:浪漫主义诗的特点。
(双选)针对的是个人情感,与古典主义不同。
)。
教授以自己为例,说自己在散步时感受到了这种互动(此处出题)与romanticism 针锋相对的一种风格是neo-classism(新古典主义),也是那位romanticism 的鼻祖很反对的。
Neo-classism(新古典主义) 使用太多的elaboration,如sky 不叫sky,而叫blue extend;bird 不叫bird,而叫feathered person。
(有题:重听题,是对古典主义诗的描述,说他们把bird 说成fly people,大概是表现古典主义诗的特征。
)教授把该诗人的作品分为三个阶段。
早期的浪漫主义作品,主要描述植物的(花与草)诗歌。
中期时是对一些社会现象做的尖锐评论。
后期时对早期的作品进行修改review。
目前,文学界还是认为它早期的作品是最好的。
教授还说,他的诗越写到后来就越写越糟糕,反而早期的比较好,本文重点讲了他第一阶段的诗)重听题,大意是说教授认为作者第一阶段的早期作品比较好,但是在课上不对以后的作品作评价,暗示了什么?本文重点讲了他第一阶段的诗。
)补充资料:ROMANTICISMRomanticism is a style in the fine arts and literature. It emphasizes passion rather than reason, and imagination and intuition rather than logic. Romanticism favors full expression of the emotions, and free, spontaneous action rather than restraint and order.Romanticism can be seen as a rejection of the precepts of order, calm, harmony, balance, idealization, and rationality that typified Classicism in general and late 18th-century Neoclassicism in particular.It was also to some extent a reaction against the Enlightenment and against 18th-century rationalism and physical materialism in general. Romanticism emphasized the individual, the subjective, the irrational, the imaginative, the personal, the spontaneous, the emotional, the visionary, and the transcendental.Romanticism in literature. During the Romantic Movement, most writers were discontented with their world. It seemed commercial, inhuman, and standardized. To escape from modern life,the Romantics turned their interest to remote and faraway places, the medieval past, folklore and legends, and nature and the common people. The Romantics were also drawn to the supernatural.WORDSWORTHWordsworth, William (1770-1850), is considered by many scholars to be the most important English Romantic poet. In 1795, Wordsworth met Samuel Taylor Coleridge. The two men collaborated on Lyrical Ballads (1798), a collection of poems frequently regarded as the symbolic beginning of the English Romantic movement.Wordsworth argued that serious poems could describe "situations from common life" and be written in the ordinary language "really used by men." He believed such poems could clarify "the primary laws of our nature." Wordsworth also insisted that poetry is "emotion recollected in tranquility."He explained that his poetry used everyday language rather than the elevated poetic language of such earlier writers as Dryden and Pope because everyday language comes closer to expressing genuine human feeling. For the same reason, he wanted to write about everyday topics, especially rural, unsophisticated subjects.Wordsworth and Coleridge lived most of their lives in the scenic Lake District of northwestern England and wrote expressively about the beauties of nature and the thoughts that natural beauty inspires. Many of their blank verse poems are written in a meditative, conversational tone new to English poetry.Wordsworth, as we have said, is the chief representative典型的of some of the most important principles原则in the romantic movement, but he is far more a member of any movement, through his supreme poetic expression of some of the greatest spiritual ideals he belongs among the five or six greatest English poets.First, he is the profoundest interpreter of nature in all poetry. His feeling for nature has two aspects. he is keenly sensitive, and in a more delicately discriminating way than any of his predecessors, to all the external beauty and glory of nature, especially inanimate nature of mountains, woods and fields, streams and flowers, in all their infinitely varied aspects. A wonderful joyous and intimate sympathy with them is one of his controlling impulses.In the second place, Wordsworth is the most consistent of all the great English poets of democracy, though here as elsewhere his interest is mainly not t in the external but in the spiritual aspect of things.The obstinacy and these poems are only the most conspicuous result of Wordsworth chief temperamental defect, which was an almost total lack of the sense of humor. Regarding himself as the prophet of a supremely important new gospel, he never admitted the possibility of error in his own point of view and was never able to stand aside from his poetry and criticize itdispassionately.题目:问题一:浪漫主义诗的特点。
托福听力经典加试题及答案(汇总鸟类迁徙Bird migrationStudent having difficulties in writing term paper原文:Conversation:term paper of bird migrationListen to a conversation between a student and his Biology professor.S: Dr. Russell, I was hoping to discuss my term paper with you I'm getting a little bit stuck here.P: Of course, so...what do you have so far? What's your topic?S: Well, I wanted to write about bird migration, but I'm having trouble finding enough sources.P: You're having trouble finding sources on bird migrationS: No, actually, on the particular aspect of bird migration that I want to write about.The thing is, I wanted to write specifically on early theories of bird migration...describe some of the theories. Like how Aristotle thought that birds changed into different species during the winter. Or how othernaturalists thought that bigger birds carried smaller birds to warmer spots for the wintertime. But I've only got a couple of books to work with right now.P: Hm...I have to admit that it's an interesting topic, and you certainly seem excited by it. But remember I told you all to ask yourselves how yourtopic is going to help you show that you can apply what you've learned this semester.A summary or description is not really what I'm looking for as much as your analysis of a certain topic.S: I guess it's not really what we're supposed to do, huhP: Right. So, how about we think about some other ideas for your paper. I mean you don't need to discard the idea completely... but... take a really different focus. Um... for example...you could present what you think are some reasons-the rationale-behind some of the erroneous theories early naturalists had. But, you'll be supporting your views with current research; those are the sources you'll need to seek out.S: Ok, I think I see what you're saying. So, like today...today we know that lots of small birds migrate at night, but maybe `cause people didn't see them-didn't see the small birds migrating-they only saw bigger birds, like geese migrating during the day. They thought that the big birds were carrying the small ones under their wings.P: There you go! That's exactly what I mean. You're showing that you're thinking about the topic, not just telling me what you read.S: Ok, I also have a really cool example of a migratory bird that I'd like to discuss in my paper. It's the Common Poorwill—I mean it seems that some Ornithologists believe that the Common Poorwill really does hibernate instead of migrating-that it's maybe the only bird that does.P: If I were you, I would stick just with migration research. Remember, this is only a 15-page paper.S: Ok, I see your point.P: But it's great that you're finding this all so interesting. I want you to come back to see me in a week so we can take a look at the new direction in your paper and evaluate the sources you've found in the meantime.中文大意:Male Student:老师,我想跟你讨论一下我的学期论文。

And to make matters worse, Rafflesi a doesn’t reproduce very well. First of all, only 10-20%of buds tum into full-fledged flowers and it can take them a year to grow. There are also male flowers and female flowers, and one of each has to be in the same area—the same vicinity—at the same time, to produce seeds, and the files that are attracted to the flower’s strongsmell have to carry pollen from one flower to the other, so how often so you think these events occur all together? Even people who study the plant for years may never witness it.1. What is the lecture mainly about?(A) The relationship between species and family.(B) The characteristics of three types of plants.(C) Difficulties classifying an unusual type of plant.(D) Unique examples of parasitic plants2. How does a strong order help Rafflesia?(A) The order is a signal to nearby plants of the opposite sex.(B) The order keeps away large predators that might eat it.(C) The order discourages parasites from growing it.(D) The order attracts files that pollinate its flowers.3. Why does the professor consider the actual classification of Rafflesia unexpected?(A) Its unusual traits are not shared by other plants in its order.(B) Its unusual characteristics were not documented until after it was classified.(C) Botanists had predicted that no other plants would be related to it.(D) Botanists had predicted that it would become extinctbefore it could be classified.4. What does the professor imply about the reproduction of Rafflesia?(A)She has witnessed it herself.(B) It does not occur often.(C) It differs from on variety of Rafflesia to another.(D) No one can understand how it reproduces.Listen again to part of the lecture. Then answer the question.It actually grows inside its host, which is a type of grapevine.I mean… it grows inside its host until itBlooms—it doesn’t bloom inside the host.5. Why does the professor say this:“I mean … it grows inside its host until it blooms—it doesn’t bloom inside the host.”(A) to given an additional example of her statement(B) to clarify her statement so students don’t misunderstand her(C) to provide evidence Rafflesia is indeed a parasitic plant(D) to emphasize the importance of the hostListen again to part of the lecture. Then answer the question.6. What does the professor imply when she says this:“But as it tums out, Mitrastemais actually related to blueberries.”(A) Mitrastema is edible.(B) Rafflesia is also related to blueberries.(C) Rafflesia and Mitrastema are not in the same order.(D) Rafflesia and Mitrastema is also related to blueberries.ANSWERS:1.

Student having difficulties in writing term paper
原文:
Conversation:term paper of bird migration
Listen to a conversation between a student and his Biology professor.
S: Dr. Russell, I was hoping to discuss my term paper with you I'm getting a little bit stuck here.
P: Of course, so...what do you have so far? What's your topic?
S: Well, I wanted to write about bird migration, but I'm having trouble finding enough sources.
P: You're having trouble finding sources on bird migration
S: No, actually, on the particular aspect of bird migration that I want to write about.
The thing is, I wanted to write specifically on early theories of bird migration...describe some of the theories. Like how Aristotle thought that birds changed into different species during the winter. Or how other
naturalists thought that bigger birds carried smaller birds to warmer spots for the wintertime. But I've only got a couple of books to work with right now.
P: Hm...I have to admit that it's an interesting topic, and you certainly seem excited by it. But remember I told you all to ask yourselves how your
topic is going to help you show that you can apply what you've learned this semester. A summary or description is not really what I'm looking for as much as your analysis of a certain topic.
S: I guess it's not really what we're supposed to do, huh
P: Right. So, how about we think about some other ideas for your paper. I mean you don't need to discard the idea completely... but... take a really different focus. Um... for example...you could present what you think are some reasons-the rationale-behind some of the erroneous theories early naturalists had. But, you'll be supporting your views with current research; those are the sources you'll need to seek out.
S: Ok, I think I see what you're saying. So, like today...today we know that lots of small birds migrate at night, but maybe `cause people didn't see them-didn't see the small birds migrating-they only saw bigger birds, like geese migrating during the day. They thought that the big birds were carrying the small ones under their wings.
P: There you go! That's exactly what I mean. You're showing that you're thinking about the topic, not just telling me what you read.
S: Ok, I also have a really cool example of a migratory bird that I'd like to discuss in my paper. It's the Common Poorwill—I mean it seems that some Ornithologists believe that the Common Poorwill really does hibernate instead of migrating-that it's maybe the only bird that does.
P: If I were you, I would stick just with migration research. Remember, this is only a 15-page paper.
S: Ok, I see your point.
P: But it's great that you're finding this all so interesting. I want you to come back to see me in a week so we can take a look at the new direction in your paper and evaluate the sources you've found in the meantime.
中文大意:
Male Student:老师,我想跟你讨论一下我的学期论文。
我卡住了,找不到这方面足够的数据。
)
Female Professor:You can’t find enough sources on bird migration
(语调上扬。
最后一题,重听题的考点。
)
Male Student:I wanted to write on theories early bird migration. 关于Aristotle对于这个题目的看法等等。
Female Professor:哦~你确实找到了一个好的题目,但是你要知道我的要求是你们的论文要反映你们这学期学了什么。
不要只是做 summary or description,我想要看到你的special analysis。
Male Student:我想,总结和描述是不够的。
Female Professor:没错,不如我们想想其他的方向。
其实你不需要完全放弃discard之前找的数据,你可以换种想法,用rational 的方式。
可以写现在的新研究(current research) 如何支持(support)或者驳斥以前的(historically) old theory。
Male Student:我想可以写bird migrate at night。
以前人们大多只看到大鸟,所以认为小鸟在大鸟的翅膀下迁徙什么的,其实新发现是,因为小鸟在夜间迁徙,人们看不到。
(通过说这个topic来验证自己理解了老师的意图change the topic from ancient to recent)
Female Professor:对,这正是我说的,你要展示你对这个主题的想法,而不是你读了哪些数据。
Male Student:I want to write about the birds that do not migrate. They hibernate during winter.
Female Professor:如果我是你,我就不会在一份15页的论文中写这么多。
Male Student:我知道妳的意思了。
Female Professor:希望你一周内再来找我,看看论文的新的方向(new direction)进行得如何。
