托福听力tpo65全套对话讲座原文+题目+答案+译文Section 1Conversation1原文Listen to a conversation between a student and an employee in the housing office. Employee: Hi. Here for your room key?Student: Actually, no, I got a bill in the mail today.Employee: Yeah, don’t worry about it. Some students got a second copy of their housing bills. You can just ignore it if you’ve already paid.Student: Yeah, no, actually it’s my phone bill. I just got it and it looks like there were all these calls made during the summer break, and I wasn’t even here. I turned in my room key at the end of last term.Employee: Right, but do you remember making arrangements to have your phone service turned off before you left?Student: Was I supposed to do that?Employee: Yeah, you were.Student: I didn’t know that.Employee: Yeah, it’s in the contract.Student: What contract?Employee: Okay, you had service with the phone company, right?Student: Sure.Employee: And you got a copy of the contract when you signed out.Student: Yeah, I guess so.Employee: Well, okay then, it’s buried in the details of the contract in fine print. And I’ve got to admit that I might not have noticed it myself but I’ve dealt with two or three other cases like this. And it does state that it’s your responsibility to cancel the service.Student: Really?Employee: I’m afraid so. You might not have seen it, but it’s in there.Student: But I thought that the housing office automatically shuts the service off when the university closes for the summer break.Employee: I’m afraid not. Classes may end for you, but the university doesn’t close down. We have a whole summer program of short courses, so it’s likely that someone who was enrolled in the summer program was assigned to your old room and when they might plug the phone in...Student: The service was already there. Oh, wow! I really made a stupid mistake. Employee: Oh, well, don’t be too hard on yourself. There is a chance we could do something. What was your old room number?Student: Baker Hall, Room 622.Employee: Okay. It looks like someone did stay there over the break. What I can do is contact them and ask them to give us a call, then we’ll explain what happened and we’ll give them your contact information.Student: Okay, but what if you don’t get a reply.Employee: Well, I hope that doesn’t happen, because if it does, then you are on your own. Again, what it comes down to is this,you signed a contract with the phone company, and there is really not much we can do to help you at this point.题目1.Why does the student go to the housing office?A. To request a telephone for her dormitory roomB. To turn in the key to her dormitory roomC. To ask about an unexpected bill she receivedD. To request an explanation about a bill she had already paid2.What mistake did the student make?A. She forgot to pay her housing fee.B. She did not cancel her telephone service.C.

So the replenishment may be needed to keep the metal high.Does that make sense? The two mechanisms are not mutually exclusive.That's what I'm trying to say.题目1.What is the main purpose of the lecture?A.To explain why people sleep at night rather than during the dayB.To discuss the problems caused by a lack of sleepC.To explain why muscles in the body need sleepD.To explore benefits that are provided by sleep but not by regular rest2.Why does the professor mention that sleep is a risky behavior?A.To suggest that resting while awake is better than sleepingB.To indicate how important the benefits of sleep must beC.To explain why many animals sleep during the dayD.To explain why birds sleep less than mammals3.According to the professor,why is the sleep of dolphins unusual?A.Their sleep is interrupted whenever they need to come up for air.B.They can move around while they are asleep.C.In every dolphin group only half of the dolphins are asleep at any given time.D.Their brains show no activity during sleep.4.What does the professor conclude about the view that the main function of sleep is to allow the body to recover from physical activity?A.It is true for all animals except marine mammals.B.It is supported by measurements of brain activity.C.It explains why sleep has evolved.D.It is not convincing when examined more closely.5.According to the hypotheses discussed by the professor,what determines howalert we feel at a particular time of the day?[Click on2answers.]A.The supply of certain chemicals in our brainB.The chemical composition of our dietC.Our24-hour cycle of mental activityD.The time of day when we usually wake up6.Why do the students say this:Male Student:Well,you know,I don't work well in the morning at all.Female Student:Yeah,I do my best work at night too.A.To show the professor that they have understood the theoryB.To support the professor's point that people tend to be active at the same timeC.To point out a fact that seems to contradict the hypothesis the professor just discussedD.To indicate that they would like to change their sleeping habits答案D B B D AC C译文教授:好的,今天我想谈谈睡眠。

Q3:In the talk, the professor describes the sequence of uranium-lead dating. Summarize the sequence by putting the events in the correct order. Drag your answer choices to spaces where they belong. A. Zircon in the sandstone is matched to the zircon in a particular mountain range. B. The amount of lead in sandstone zircon is measured C. The age of zircon in a sandstone sample is determined
the age of one of your mountain ranges, then it means the sandstone actually used to be part of that particular mountain range. Is everybody with me on that? Good. So, in this case, UraniumLead Dating was used to establish that half of the sandstone in the samples was formed at the same time the granite in the Appalachian Mountains was formed. So because of this, this new way of doing Uranium-Lead Dating, we’ve been able to determine that one of our major assumptions about the Grand Canyon was wrong.

So you want to know when it's safe to explore them.Unfortunately,it'll be dry this weekend.Now,these deep,narrow slots are pretty common.You might even have two of them very close to each other with only a thin wall of rock in between.Of course,frost wedge is still at work,so it starts wearing away at the front of the thin wall until you get a whole I mean a hole all the way through the wall,front to back.And this hole gets bigger and bigger.Once it's at least one meter in diameter,it's called a window.And eventually the weight on top of it is just too much,so the roof caves in and only the sides,sometimes it's just one side is left standing.These sides,which look a lot like collins,now are called Hudos.Here's a photo of something we'll be seeing.One of the things that makes Bryce canyon unique is that it has more Hudos than anywhere else in the world.Yes,Margot?Female student:Why is it so lumpy looking?You'd think it would be smoother.Professor:Well,remember,these are sedimentary rocks,so they have layers.Some layers are mostly limestone,and limestone erodes pretty quickly in the presence of any kind of acid.Now Bryce canyon in a very unpolluted area,but even,there the rain water has a little carbolic acid in it,which causes the limestone to erode.But other layers are made up of different types of sediment,which aren't so vulnerable to acid,so they don't erode as quickly.题目1.What is the lecture mainly about?A.The length of time required to produce sedimentary rocksB.The role of climate conditions in the creation of sedimentary rocksC.Some processes that produced a specific group of rock formationsD.Some unique geologic features found in canyons in the United States2.According to the professor,what is one characteristic that frost wedging and runoff share?A.Neither occurs in a desert.B.Neither is a frequent event.C.Both are weathering processes.D.Both are seasonal phenomena.3.Why does the professor show a picture of a slot canyon?A.To give students a sense of the size of a typical slot canyonB.To show students one of the places they will visit on their field tripC.To illustrate how many sediment layers are visible in a typical slot canyonD.To show how much slot canyons can vary based on local climate conditions4.What is the professor's attitude toward students exploring Bryce Canyon on their own?A.He worries that students may not know to take appropriate precautions if they go by themselves.B.He suspects that many students will not go on their own if such a trip requires them to get up early.C.He hopes that the class field trip will motivate students to visit Bryce Canyon on their own.D.He believes that students learn more from individual exploration than they dofrom being in a group.5.How is a hoodoo formed?A.Runoff produces large gravel deposits.B.Air pollution leads to a buildup of limestone.C.The roof of a rock window collapses.D.A flash flood washes away the base of a rock wall.6.According to the professor,what two factors explain why a hoodoo does not have a smooth shape?[Click on2answers.]A.The presence of acid in rainwaterB.The temperature swings between the summer and the winter seasonsC.The composition of the hoodoo's sedimentary layersD.The location of the cracks created by frost wedging答案C D A A C AC译文听一段地质学的讲座。

托福听力经典加试
1.托福听力经典加试之Lecture: 大王花
植物分类归属问题,单靠外观是不能判断的,相似的植物不一定是一类,反之亦然。

说了印度的某一种吃肉的大红花,给了图片(图片有点恶心)。

这花的特点:(1)大。

直径1米;(2)发出气味,能把苍蝇吸引过来。

一开始根据它的这两个特征,将它归类到一个order(这个属种都很大的花),后来发现不对。

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。

后来终于找到了它的营地,但是这个属种(好像有violate, willow之类)的花都很小,而且没有异味。

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。

大意是说大王花又大又臭将物种分门别类其实不是件容易的事,例如:大王花,解释了一些特性,如散发恶臭吸引flies 来授粉pollination ,光透过这些特性很难把他归类,与他同一order的另一种植物,与大王花天壤地别。

一开始以为是和m^^什么一类,后来发现不是。

学生问为何不用植物DNA鉴识,教授说后来终于鉴定出来是什么类了,但是它和该类的植物差别很大~~,所以无效。

另外,大王花不容易繁殖,观察的机会也不多。

讲生物的分类分属,一种忒独特的植物,只有马来西亚和印度尼西亚有,是霸王花!忒大长得,气味也忒大,吸引苍蝇的!不过照片上看还不错,但是不好分类,一般是根据外形分类,就分了一类,但是觉得不该这么分。

同学问,,可以用超级先进的DNA嘛。

然后教授回答,晕,废话,早就想到了,可是………DNA也没办法。

(说似乎这种花有什么光合作用的化学物质,)但是不能进行光合作用,不能自已从太阳获得能量,就很BT的长出东东伸到
别的植物那里去吸养分。

晕,所以DNA不准。

哦还有,这霸王花很稀少稀少了,然后繁殖也很难,也是那种雌雄异体的,传播花粉,但是这样都还是很难繁殖,有多难呢?教授自问自答,说反正对这种植物研究多年了的人都没看到过。

2.托福听力经典加试之鸟类迁徙bird migration
内容简介:一个学生找老师因为他要写的bird migration的报告,但找不到足够多的材料,老师认为不可能材料不够(有问题出现,问教授这话什么意思,答案是她认为找resource应该easy),男生说因为他要写得paper是关于古代鸟类迁徙的,所以资料不够。

教授的说:“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。


后来他说想写关于Aristotle关于这个题目的看法之类的,老师说她的要求是希望他们运用所学知识研究来完成paper 不要做summarization,希望他换一种想法,可以写以前的old theory,然后现在的这些新研究如何支持或者驳斥这些theory,接着他想到可以写bird migrate at night,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晚上飞(有问题出现,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)。

后来他又想写一种不迁徙而是冬眠的鸟,又被老师拒绝了,老师说才15页的报告就不要那么折腾成这样,但是想法挺不错。

最后老师希望他一周后再来一下,看一看他确定的方向。

3.托福听力经典加试之主题:女学生丢了钱包
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 service办id 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 card,dorm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 的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)。
