主题:神经胶质细胞研究
5 p8 C+ \2 F: R# b# m5 N内容简介: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bioelectricity(生物电) 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(有题目出现,问教授打断他的用意)glial cells(神经胶质细胞)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。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开阔的领域,建议学生们可以考虑毕业后作深入研究(有题目出现)

分析:本篇文章所涉及的正是托福听力中最难的关于生物学方面的知识,所以其中的生词非常多,比如glial cell等,但是同学们要注意,凡是托福听力中涉及到的生词,都会出现一些解释原则对其进行解释说明,比如会出现which means等词语。

biology glial cell(神经胶质细胞)。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(神经胶质细胞)研究的很少,一直被忽略,被看作help the growth of neurons(有题目出现),起辅助作用。4 C7 u6 Z& k/ |8 [4 |6 q  i1 C

后来偶然发现大脑中glial cell(神经胶质细胞)比neuron(神经细胞)的数目多很多,glial cell(神经胶质细胞)引起了科学家的重视,开始研究它究竟起什么作用(有题目出现,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(有题目出现)。传统观点一直误以为glial cell也像nerve cell一样用电信号。后来谈到glial cell可能的作用:使人更intelligent- D$ e5 s/ y0 S/ d. G/ n9 _

本文涉及到的背景知识介绍:Glial cell is thought to help the growth of neurons. However scientists accidentally discover that glial’s amount is much more than the neuron. So glial attract people’s attention.

Glial cells (神经胶质细胞)and Neurons (神经细胞):Glial cells commonly called neuroglia or simply glia are non-neuronal cells that provide support and nutrition maintain homeostasis form myelin and participate in signal transmission in the nervous system. In the human brain glia is estimated to outnumber neurons by about 10 to 1.

They are thus known as the "glue"胶水 of the nervous system. The four main functions of glial cells are to surround neurons and hold them in place to supply nutrients and oxygen to neurons to insulate one neuron from another, and to destroy pathogens and remove dead neurons." i' X/ g/ _. r  X; H
Glia was discovered in 1856 by the pathologist Rudolf Virchow in his search for a 'connective tissue' in the brain. The human brain contains about ten times more glial cells than neurons. Following its discovery in the late 19th century this fact underwent significant media distortion emerging as the famous myth claiming that "we are using only 10% of our brain".

内容简介:女生的钱包中里面有她的student id& meal card以及 key等东西,无法回dorm。于是去student serviceid card,遇到staff(口音是黑人)把守,说没有id card 不能进去,要么出示driving license,要么是有头像照片的证件,比如passport或者其他。但是女生说,我的wallet丢了,id card没了,passport也在dorm里面,而没有id carddorm不让进(有题目出现,问她为什么拿不到passport)。后来女说这个问题她和dorm负责人说过,有email 到这里做说明。staff查了查,果然如此,然后staff又说如果你能正确说出passport number,就让她进去,女学生从容的说出了number,他说OK,你可以进去了,但是你会受到监视。女生说who cares! 女生又说了:她的meal card也掉了。管理员说:你在里面办ID的时候也可以顺便办了meal card。女生说:你真的是帮了我很大的忙啊!管理员:if you have some other problems, I am glad to help you。女生说you help! (本句语气为降调,有问题出现,问女生为什么这么说。此题两个选项为正确选项:1、女生怀疑这个管理员是不是能帮他。 2、女生在解决了所有的问题之后如释重负)

分析:本篇文章属于对话类文章,涉及的内容为学生的日常生活以及学习生活。这类文章的难点在于会出现有些在外国大学中会出现的一些专有名词,比如id card, meal card等等,这些名词是我们在中国大学中不会看到的,所以需要同学们事先按照我们的场景分类法对该场景的词汇进行总结记忆。另外,本篇文章涉及到了一些关于句子语气语调的解释,不同的语气语调该句话的意思就会产生变化,比如最后一句话you help!。这是一道双选题,要根据女生的语气进行选择。

主题:浪漫主义诗歌8 k1 e# e2 n3 e7 t% p% m6 y
内容简介:主要介绍18-19 世纪英国浪漫主义(Romanticism)诗歌的代表人Wordsworth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(有题目出现)Romanticism不是我们平时理解的romance,和男女之间的爱情无关。Romanticism针对的是common people而不是少数educated people,用的是simple language,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。教授以自己为例,说自己在散步时感受到了这种互动(有题目出现)romanticism针锋相对的一种风格是neoclassicism新古典主义,也是那位romanticism的鼻祖很反对的。neoclassicism使用太多的elaboration,如sky不叫sky,而叫blue什么的;bird不叫bird,而叫feathered person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的评论。后期时对早期的作品进行修改。目前文学界还是认为它早期的作品是最好的。教授还说,他的诗越写到后来越糟糕,反而早期的比较好,本文重点讲了他第一阶段的诗。

本篇文章中涉及到了一道举例题,比如文章中教授会用自己的一个经历举例子,然后问教授为什么说这个例子,学生在听文章的时候应该注意到比如for example等词句,文中一旦出现例子,一定会有考题出现。另外,文章涉及到了一个事物的分类,像这种分类的情况,一定也会涉及到考题,比如填表体等等。所以考生在听得过程中,应该记住是怎么分类的,并且记住每一类的具体特征即可。6 R& P: F7 ]) A/ G7 e$ {9 s
l' U5 p5 u( J6 ~; K6 A7 t
本文涉及到的背景知识介绍:Wordsworth, as we have said, is the chief representative of some of the most important principles 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.7 u  G# T" ^6 ~1 z. _, b9 l4 J# O
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
/ i: \6 M% k5 p' v" nIn 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 in the external but in the spiritual aspect of things
. I: k( u' u# {' r1 \4 \) oThe obstinacy and these poems are only the most conspicuous result of Wordsworth’s 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 it dispassionately.

( t' D/ ]5 i0 i* D% aHe cannot find sufficient material for the bird migration. But the teacher thinks it is impossible. They he wants to write some ideas from Aristotle.

2 X, D0 u9 H8 |, {9 g* j8 n3 F内容简介:Ragtime介绍了一种流行于美国十九世纪左右名为ragtime的音乐,能够表现年青人的活力(spirit of youth)之类的,此乐流行是由于piano的关系,因为两者真是太搭配了。在那个年代,在各种场合都用钢琴。此乐当时流行程度,就像Rock & Roll在某一时期一样。(有问题出现,女学生说了一堆后,来了一句 I just don't get it,意思是要教授explain,还说piano 之所以当时那么受欢迎,一是因为它能与音律产生和谐,另一是因为当时它算一种财富地位的象征什么的symbol of wealth and status。再加上那个年代,大家都没钱,就去public concert or restaurant什么的听音乐,而piano声音够响亮,又和ragtime music rhythm搭配的天衣无缝,所以,两者相得益彰这个音乐年轻人很喜欢,因为很有激情。除了到处演出啊,park演出等不用钢琴,因为难搬(有考点出现,because of transportation problem。同时,此乐也是 jazz的前身,因为演奏者不按牌理出牌,一首曲七个人弹,弹出七种调。这种ragtime音乐影响很远啊,例如现在的jazz就是从那发展来的。) f, |4 s+ J3 }) O# b( A

本文涉及到的背景知识介绍:Ragtime 拉格泰姆音乐(1890-1915期间在美国流行的一种音乐) Ragtime is an American musical genre which enjoyed its peak popularity between 1899 and 1918. It has had several periods of revival since then and is still being composed today. Ragtime was the first truly American musical genre, predating jazz. It began as dance music in popular music settings years before being published as popular sheet music for piano. Being a modification of the then popular march, it was usually written in 2/4 or 4/4 time (meter) with a predominant left hand pattern of bass notes on odd-numbered beats and chords on even-numbered beats accompanying a syncopated melody in the right hand. A composition in this style is called a "rag". A rag written in 3/4 time is a "ragtime waltz".
$ l$ M1 Z/ y0 f' a% w4 M- |8 I( ^' T% W9 S
Ragtime is not a "time" (meter) in the same sense that March time is 2/4 meter and waltz time is 3/4 meter; it is rather a musical genre that uses an effect that can be applied to any meter. The defining characteristic of ragtime music is a specific type of syncopation in which melodic accents fall between metrical beats. This results in a melody that seems to be avoiding some metrical beats of the accompaniment by emphasizing notes that either anticipate or follow the beat. The ultimate (and intended) effect on the listener is actually to accentuate the beat, thereby inducing the listener to move to the music. Scott Joplin, the composer/pianist known as the "King of Ragtime", called the effect "weird and intoxicating". He also used the term "swing" in describing how to play ragtime music: "Play slowly until you catch the swing...". The name swing later came to be applied to an early genre of jazz that developed from ragtime. Converting a non-ragtime piece of music into ragtime by changing the time values of melody notes is known as "ragging" the piece. Original ragtime pieces usually contain several distinct themes, four being the most common number.

0 g* y- {# f( C3 L$ _5 K; e7 ?内容简介:教授一开始就介绍植物分类,提到分类中的species种,genus属,order目。说植物的classification 很难,一些特性比较特殊的植物特别是这个样子。提出植物的分类不能完全依靠它flower的形态和特性。提到Rafflesia(大王花),开花石会散发腐臭的味道,以吸引蝇类传播花粉。她举了Indonesia的一种植物M,它的flower很特别,超级大(图片显示它的直径有一个手臂这么长,颜色为绛红),有难闻的味道,象什么肉,但是最后发现他们不是一个order 的。生长在很恶劣的环境中,其它的植物都不能生长(有题目出现:它生长在什么样的环境当中? 这种植物有事物的来源,但是它还是会抓insect吃,因为它不能从土壤中得到足够的营养,所以要通过这种方式来获取所需的营养(有题目出现:为什么吃虫子)。然后教授说了它怎么抓虫的? 经过很长时间的研究,专家发现它和violet(紫罗兰)willow(柳树) 等是属于一个order的,后提到幼时的violet,也会散发那种smell的。提到共存(有题目出现)有提到另一种南美洲的植物和它是同一目的,但是花很小,味道也不难闻,与蓝莓共生coherent。学生提问不能测DNA吗,教授说这种大花基本不进行光合作用,没法提取一般植物能提取到的DNA。在DNA分析技术成熟之前根本无法将他们并为同类,由于他们的特征差异太大。教授还提到这种植物的交配不易,其一气味难闻致使传蜜的动物不易接近,其二它每年只开一次花,且花分雌雄。所以要这么多先天条件凑齐不易,所以很少有人有机会看到开花的全过程。(有考题出现)所以,结论,不可以貌取人。后来又讲了这种花很有可能灭绝,原因是要fly帮忙运花粉,要同种的花在一起,要这些条件同时发生,是小概率事件。Small incident
