教授：有一天我跟物理系的一位同事聊天，聊到一个发现有可能会改变所有的事情。他提到相
对论彻底地改变了物理学。不管怎样，这段对话是我想到了考古发现的确改变了我们对古代文明的
看法。所以我想要讲一下自动回转式天球仪的发现。自动回转式天球仪是在一百年前在地中海的一
艘古希腊的沉船的残骸中发现的。被发现时它已经破烂不堪，被腐蚀成许多碎片。但当发现了它到
底是什么以后，我们便重新组装了它。我实在是无法用语言表达这个发现有多么的不寻常。自动回
转式天球仪是一个相对较小的装置，大概跟鞋盒一样大，是在一个木盒中装了齿轮的装置。在原型
中，在顶部有旋转的刻度盘和其他的指示器，上面用字母和图画太阳，月相和不同的星座。在盒子
内部，铜的齿轮旋转以改变显示的内容。显示的内容，也就是天球仪的指示器会转动并显示出太阳、
月亮和行星的运行。这个装置可以用来表示月相和更多的信息。最近，科学家对这个机器上的雕刻http://bailiedu.com进行了分析，并再次检查了沉船上的其他货物，有明确的证据证明这个装置可以追溯到公元前150
年到公元前100年的古罗马时代。令人感到惊
讶的是在天球仪之前，人们知道的最早的能够测算太阳和约球轨道的仪器是在此以后的1000
年才发明的。所以最初发现是，人们确实无法相信。我的一些同事坚持认为它肯定是在公元前100
年以后才被发明出来的。但是物理证据是不可否认的，它的确是那么古老的。当然关于天球仪还有
一个不寻常的发现，那就是它是由铜构成的。并不是说那是铜在希腊十分罕见，而是铜十分贵重而
且容易回收。
一个对金属有所了解的人就可以轻易地将铜溶解并重新锻制。比如说，做成硬币。那时铜用来
铸币。又或者将铜做成其他有价值的东西。十分幸运的是这个装置被淹没在水下，否则它就又能被
回收利用了做成什么呢?谁知道呢。现在，要弄清楚天球仪是一个挑战。他被淹没在水下长达两千年
才被发现。而且发现了它，我们还要许多年来弄清楚它是什么。你想这个装置在水下已经被腐蚀了，
许多齿轮都粘在一起一团糟。只有一下部分被清理干净。只有当应用了伽马射线后我们对内部的结
构有所了解，就像用X光用来观察大家的骨骼一样。在仔细地观察了内部结构以后，人们发现这是
一个十分复杂的装置。这些齿轮的转动并不仅仅能显示出月相。天球仪还能够显示出农历和公历。
还有，这些出轮的运动还符合行星的运行并预报日蚀和月蚀。但是最引人注目的是这个装置十分精

TPO23Lecture4Choreography(Screen Dance)
Professor：Now,when you think about
choreography,well,uh,for your last assignment,you
choreographed the dance that was performed on stage in front
of live audience.Now,screen dance is very different.It is a dance
routine you will be choreographing specifically to be viewed on
a screen,on a computer screen,a TV screen,in a movie theater,any
screen.So the question we have to ask is,what's the difference
between choreography for a live performance and choreography
for on-screen viewing?OK. Think for a minute.When you see a
movie,is it just a film of people acting on a stage?Of course not.
Movies use a variety of camera angles and creative

托福TPO23听力Conversation2文本
Narrator: Listen to a conversation between a student and his English professor.
Professor: Hi, Bob. How is it going? Are you enjoying the Introduction to
Literature class?
Bob: Yeah, it's great. Araby, that short story by James Joyce we read last week,
it was awesome.
Professor: I'm glad you like it. Most of Joyce's work is very complex. A lot of
students say that he is hard to understand. Normally, you wouldn't tackle Joyce in
an Intro class, but I'd like to give my first year students a taste of his style,
his psychological approach to literature, because, mainly because it influenced other
writers.I only wish we had more class time to discuss it.
Bob: Me too. So why did you pick Araby instead of some other story?

TPO 1 Lecture 1Contemporary artListen to part of a lecture in a contemporary
art class.
ProfessorOk, I’m going to begin this lecture by giving you your next
assignment. Remember I said that at some point during this semester I wanted
you to attend an exhibit at the Fairy Street Gallery and then write about it?
Well, the exhibit that I want you to attend is coming up. It’s already started
in fact, but it’ll be at the gallery for the next month, which should give you
plenty of time to complete this assignment.
The name of the artist exhibiting there is Rose Frantzen. Frantzen’s work
may be unfamiliar to you since she’s a relatively young artist. But she’s got
a very unusual style, compared to some of the artists we’ve looked at this term.
