Before we start our first lab, I'd like to tell you a little bit about the workbook we'll be using. The first thing I'd like to point out is that the workbook contains a very large amount of material, far more than you could ever handle in a single semester. What you're supposed to do is choose the experiments and activities that you want to do—within a certain framework, of course. Part of my job is to help you make your choices. Next, I'd like to mention that in each workbook chapter, there are usually two subsections. The first is called "Experiments" and the second is called "Activities." In the "Experiments" section, the workbook gives full instructions for all the experiments, including alternate procedures. Choose the procedure you wish—there's plenty of equipment available. In the "Activities" section, you will find suggestions for projects that you can do on your own time. You'll see that there are usually no detailed instructions for the activities—you're supposed to do them your own way. If there are no questions, let's turn to Chapter One now.

在开始我们的第一个实验之前，我想要告诉你们一些关于我们将会用到的作业本的事情。我想指出的第一件事情是这个作业本包含了大量的资料，比你在一个学期能处理的资料要多的多。你应该做的是选择一个你想做的实验并在一个确定的体系下完成它。帮助你做出你的选择是我工作的一部分。接下来我想说到的是，在作业本的每一章通常有两部分。第一部分叫做“实验”，第二部分叫做“活动”。在“实验”部分，作业本上会给出完整的实验指令，包括可替换的步骤。选择你喜欢的步骤——这里有很多步骤可供选择。在“活动”部分，你会找到一些可以在闲暇时间进行的关于方案的建议。你会看到这里通常没有详细的活动指示——你应该用自己的方法去完成它们。如果没有其他问题，让我们现在进入第一章。

Archaeologists have been trying to determine how the buildings were used. While there is still no universally agreed upon explanation, there are three competing theories. One theory holds that the Chaco structures were purely residential, with each housing hundreds of people. Supporters of this theory have interpreted Chaco great houses as earlier versions of the architecture seen in more recent Southwest societies. In particular, the Chaco houses appear strikingly similar to the large, well-known "apartment buildings" at Taos, New Mexico, in which many people have been living for centuries.

托福TPO12综合写作阅读原文+听力原文+满分范文

为了帮助大家高效备考托福，为大家带来托福TPO12综合写作阅读原文+听力原文+满分范文，希望对大家备考有所帮助。 托福TPO12综合写作阅读原文文本： Jane Austen (1775-1817) is one of the most famous of all English novelists, and today her novels are more popular than ever, with several recently adapted as Hollywood movies. But we do not have many records of what she looked like. For a long time, the only accepted image of Austen was an amateur sketch of an adult Austen made by her sister Cassandra. However recently a professionally painted, full-length portrait of a teenage girl owned by a member of the Austen family has come up for sale. Although the professional painting is not titled Jane Austen, there are good reasons to believe she is the subject. First, in 1882, several decades after Austen's death, Austen's family gave permission to use the portrait as an illustration in an edition of her letters. Austen's family clearly recognized it as a portrait of the author. So, for over a century now, the Austen family itself has endorsed the claim that the girl in the portrait is Jane Austen. Second, the face in the portrait clearly resembles the one in Cassandra's sketch, which we know depicts Austen. Though somewhat amateurish, the sketch communicates definite details about Austen's face. Even though the Cassandra sketch is of an adult Jane Austen, the features are still similar to those of the teenage girl in the painting. The eyebrows, nose, mouth, and overall shape of the face are very much like those in the full-length portrait. Third, although the painting is unsigned and undated, there is evidence that it was painted when Austen was a teenager. The style links it to Ozias Humphrey, a society portrait painter who was the kind of professional the wealthy Austen family would hire. Humphrey was active in the late 1780s and early 1790s, exactly the period when Jane Austen was the age of the girl in the painting. 托福TPO12综合写作听力原文文本： Professor：The evidence linking this portrait to Jane Austen is not at all convincing. Sure, the painting has long been somewhat loosely connected to Austen's extended family and their descendants, but this hardly proves it's a portrait of Jane Austen as a teenager. The reading's arguments that the portrait is of Austen are questionable at best.First, when the portrait was authorized for use in the 1882 publication of her letters, Jane Austen had been dead for almost 70 years. So the family members who asserted that the painting was Jane had never actually seen her themselves. They couldn't have known for certain if the portrait was of Austen or not.Second, the portrait could very well be that of a relative of Austen's, a fact that would explain the resemblance between its subject and that of Cassandra's sketch. The extended Austen family was very large and many of Jane Austen's female cousins were teenagers in the relevant period or had children who were teenagers. And some of these teenage girls could have resembled Jane Austen. In fact, many experts believe that the truesubject of the portrait was one of those relatives, Marianne Kempian,

老托福听力93篇(87-88)-These days we take

老托福听力93篇(87-88)-These days we take 87 These days we take for granted the wide variety of music available on the radio. But, this wasn't always the case. In the early days of radio, stations were capable of broadcasting only a narrow range of sounds, which was all right for the human voice but music didn't sound very good. There was also a great deal of crackling and other static noises that further interfered with the quality of the sound. A man named Edwin Armstrong, who was a music lover, set out to change this. He invented FM radio, a technology that allowed stations to send a broad range of frequencies that greatly improved the quality of the music. Now, you'd think that this would have made him a millionaire; it didn't. Radio stations at that time had invested enormous amounts of money in the old technology. So the last thing they wanted was to invest millions more in the new technology. Nor did they want to have to compete with other radio stations that had a superior sound and could put them out of business. So they pressured the Federal Communications Commission, the department of the United States government that regulates radio stations, to put restrictive regulations on FM radio. The result was that its use was limited to a very small area around New England. Of course as we all know, Edwin Armstrong's FM technology eventually prevailed and was adopted by thousands of stations around the world. But this took years of court battles and he never saw how it came to affect the lives of almost everyone. 【生词摘录】 1. crackling: n. [C]爆裂声 2. static: adj. 静电的 3. FM: 调频(frequency modulation) 4. frequency: n. [C]频率 5. millionaire: n. [C]百万富翁，大富豪 6. restrictive: adj. 限制性的 7. regulation: n. 规则，规章 8. prevail: v. 流行，盛行，获胜，成功 9. adopt: v. 采用 88 I'm going to talk about a train that exemplifies the rise and fall of passenger trains in the United States: the Twentieth Century Limited. Let me go back just a bit. In 1893, a special train was established to take people from New York to an exposition in Chicago. It was so successful that regular service was then set up between these cities. The inaugural trip of the Twentieth Century Limited was made in 1902. The train was different from what anyone had ever seen before. It was pulled by a steam engine and had five cars: two sleepers, a dining car, an observation car, and a baggage car, which, believe it or not, contained a library. The 42 passengers the train could carry were waited on by a large staff. There were even secretaries and a barber on board. It wasn't long before people had to wait two years to get a reservation. As time passed, technical improvements shortened the trip by a few hours. Perhaps the biggest technological change occurred in 1945, the switch from steam to diesel engines. By the 1960's, people were traveling by car and airplane. Unfortunately, the great old train didn't survive until the end of the century it was named for. 【生词摘录】

托福听力TPO1原文 Lecture 4

下面就让小编来为大家介绍一下托福听力TPO1原文中Lecture 4的文本内容吧，大 家要好好把握，这些都是非常有价值的材料，希望能够给准备托福听力的同学带来帮助。 TPO 1 Lecture 4BiologyNarratorListen to part of a lecture in a biology class. ProfessorFor today’s discussion, we’ll review the case study on how some animals have behaviorally adapted to their environments. Now you had to read about two animal species, the Eastern marmot and the Olympic marmot. Marmots are rodents. They are large ground squirrels, about the size of an average house cat. And they live in a variety of habitats. And even though they spend the significant portion of the year hibernating, according to this case study, marmots are still considered excellent subjects for animal behavioral studies. Why is that? StudentWell, when they are not hibernating, you can find them in open areas. And they are pretty active during the day, which makes them easy to observe, right? ProfessorUh-huh, so first let’s discuss the Eastern marmots. They reside throughout the eastern region of North America where there is a temperate climate, where the growing season lasts for at least five months of the year, which is when they do all their mating, playing and eating. StudentOh, I see. At first I wasn’t sure what growing season meant, just from the reading. But now I get it. It's the amount of time it takes for them to grow, right? So it would be five months? ProfessorUmm? Oh, uh… I’m sorry but no. It has nothing to do with that. It's not about the time it takes for Eastern marmots to grow. It’s when the food is available. That is when it’s not covered in snow and there is no frost covering the grass and, umm, vegetative parts of a plant’s herbs and the flowers the marmots like to eat. So growing season refers to the availability of the food they eat, OK? So now how would you describe the Eastern marmots’ social habits? StudentWell, they are really territorial, and loners, and just so aggressive even with other Eastern marmots. And their mating ritual is just so impersonal. ProfessorUh-huh? Now when they emerge in the spring from hibernation, the mating process begins. For them, well, they come together to mate and then they

老托福听力93篇(45-46)-So, why did what is now

老托福听力93篇(45-46)-So, why did what is now 45 So, why did what is now called "modern dance" begin in the United States? To begin to answer this question, I'll need to backtrack a little bit and talk about classical ballet. By the late 1800's, ballet had lost a lot of its popularity. Most of the ballet dancers who performed in the United States were brought over from Europe. They performed using the rigid techniques that had been passed down through the centuries. Audiences and dancers in the United States were eager for their own, "contemporary" dance form. And, so, around 1900, dancers created one. So, how was this "modern" dance so different from classical ballet? Well, most notably, it wasn't carefully choreographed. Instead, the dance depended on the improvisation and free, personal expression of the dancers. Music and scenery were of little importance to the "modern" dance, and lightness of movement wasn't important either. In fact, modern dancers made no attempt at all to conceal the effort involved in a dance step. But even if improvisation appealed to audiences, many dance critics were less than enthusiastic about the performances. They questioned the artistic integrity of dancers who were not professionally trained and the artistic value of works that had no formal structure. Loie Fuller, after performing Fire Dance, was described as doing little more than turning "round and round like an eggbeater." Yet, the free, personal expression of the pioneer dancers is the basis of the "controlled freedom" of modern dance today. 【生词摘录】 1. backtrack: v. (由原路)返回，后退 2. ballet: n. [C]芭蕾舞 3. rigid: adj. 严格的 4. contemporary: adj. 当代的 5. choreograph: v. 设计舞蹈动作，精心编排 6. improvisation: n. 即席创作 7. scenery: n. 舞台布景 8. lightness: n. 轻盈，灵活 9. conceal: v. 隐藏 10. eggbeater: n. [C]打蛋器 11. pioneer: adj. 先驱，创始人 12. controlled freedom: 克制的自由 46 Today I want to discuss fossil fuels such as coal, oil, and natural gas. The term "fossil fuel" refers to the trapped remains of plants and animals in sedimentary rock. You see, living plants trap energy from the sun by the process of photosynthesis, and they store the energy in their chemical compounds. Most of that energy is released when the plant dies and decays. However, sometimes organic matter is buried before it decays completely. In this way some of the solar energy becomes trapped in rocks, hence the name fossil fuel. Although the amount of organic matter trapped in any one growing season is small, the accumulated remains from millions of years are considerable. Because the accumulation rate is so slow, millions of times slower than the rate at which we now dig up this organic matter and

0401 W: Hey Steve, got any plans for tonight? M: Hi, Jane. No, I don't think so. Why? Got any suggestions? W: In fact, I do. I just got two tickets to the opening of the exhibit of the reprints by Julia Margaret Cameron. I would have tomention it earlier, but I was on the waiting list for these tickets and I wasn't sure I'd even get them. M: An exhibit, huh? I like such things. But I don't know who Julia…… W: Margaret Cameron! She was a photographer in the 1800s. She is interesting to art-historians in general and students ofphotography in particular because she ... how should I say, change the aesthetics for photography. M: What do you mean? W: Well, her specialty was portraits and instead of just making a factual record of details like most photographers did, you know, justcapturing what a person look like in a dispassionate thought of way. She, like a portrait painter, was interested in capturing hersubject's personality. M: Interesting! How did she do that? W: She invented a number of techniques that affect the picture. Like one of these things she did was blur images slightly by using asoft focus on the subject. That's pretty common now. M: Yeah, seen that. Who did she photograph? W: Famous people of her day, Alfred Lord Tennyson, Henry Wadsworth Longfellow, Charles Darwin, I don't know who else. We'll seeat the exhibition. M: You really pick my curiosity. I am going to enjoy this. 31. What is the conversation mainly about? (A) A famous photographer 32. What did Julia Margaret Cameron emphasize in her portraits? (C) Her subject's personality 33. According to the conversation, what unique photographic technique did Margaret Cameron use? (D) Soft focus 34. What will be the subject of the pictures at the exhibit? (C) Well-known people M: Do you want to the movies with on Saturday? W: Thanks, but I have to study my research project. I'm taking that same anthropology course you took with Prof. Grady. M: The one on ethnographic interviewing? Oh, good! I'm sure you'll get a lot out of it. W: I have to admit the word "ethnography"(人种学) scared me a little at first. It seems so technical. But then when she explained that it's what anthropologists do, you know, how they investigate and record aspects of a culture, I didn't seem so intimidating! M: Yeah, it's all part of the fields work anthropologists conduct and it's good to start doing that now before you become a graduatestudent and have to conduct large projects yourself. Who are you going to interview? W: You know the publishing office where I used to work? Vivian, the woman I worked for, she's been a manager there for over 30years and had seen a lot of changes in the industry. I thought I'd start out by interviewing her about how the people in the officeinteract with each other and with outside clients. M: Isn't it funny how we use the thing that anthropologists study to foreign cultures and had the travel halfway across the world to doit? The best part of that course is that it shows you that ethnographic research can also be done on a familiar ground. W: Yeah. I got the idea from my project from reading Robert Marshal's study of office life and I
