托福聽力解題思路指導

 在聽TOEFL 聽力講座材料完成題目的時候,明辨文章的結構關系能夠幫助學生更好的完成對應的題目。在TOEFL 聽力講座材料中，通常有如下的結構：1). 定義; 2). 描述與例子; 3). 分類; 4). 順序; 5). 對比與比較; 6). 原因與結果; 7). 問題與解決方法; 8). 建議與總結。以TPO前4套為例，歸類這8種結構及對應的問題：

1.定義結構(Definition)

例：TPO2 L1, Muscle activities and thinking (Psychology)

2.描述與例子(Description and Example)結構

例：TPO2 L2, Manila hemp (Biology)

聽力文本:

They have one more characteristic that’s very important, and that is that they are exceptionally resistant to salt water. And this combination of characteristics—long, strong, flexible, resistant to salt water—makes Manila hemp a great material for ropes, especially for ropes that are gonna be used on ocean-going ships. In fact, by the early 1940’s, even though steel cables were available, most ships in the United States Navy were not moored with steel cables; they were moored with Manila hemp ropes. Now, why was that? Well, the main reason was that steel cables degrade very, very quickly in contact with salt water.

對應問題:

16. According to the professor, what was the main reason that many ships used Manila hemp ropes instead of steel cables?

A. Manila hemp was cheaper

B. Manila hemp was easier to produce

例1：TPO4 L4, American government supporting art (US Government)

聽力文本:

But the first attempt the United States government made to, you know, to support the arts was the Federal Art Project…So, moving on, we don't actually see any govern…well any real government involvement in the arts again until the early 1960s, when President Kennedy and other politicians started to push for major funding to support and promote the arts…And for just those reasons, in 1965, the National Endowment for the Arts was created…And by the mid-1970s, by 1974 I think, all fifty states had their own arts agencies, their own state arts councils that work with the federal government with corporations, artists, performers, you name it…But they only succeeded in taking away about half the annual budget.

對應問題:

31. The class discusses some important events related to government support for the arts in the United States. Put the events in order from earliest to latest. The earliest one is The government provided no official support for the arts.

答案：C-D-A-B

例2：TPO1 L2, Uranium-Lead Dating (Geology)

聽力文本:

So if you measure the amount of Lead in the Zircon grain, you can figure out when the grain was formed. After that, you can determine the age of Zircon from different mountain ranges. Once you do that, you can compare the age of the Zircon in the sandstone in your sample to the age of the Zircon in the mountains. If the age of the Zircon matches the age of one of the mountain ranges, then it means the sandstone actually used to be part of that particular mountain range.

對應問題:

14. 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. To remove an answer choice, click on it

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

答案：B-C-A

5.比較與對比(Comparison and Contrast)

例：TPO1 L4, Olympic Marmot & Eastern Marmot (Biology)

聽力文本:

P: So now how would you describe the Eastern marmots’ social habits?

S: Well, they are really territorial, and loners, and just so aggressive even with other Eastern marmots. And their mating ritual is just so impersonal.

P: Uh-ha. Any contrast, the Olympic marmots? What about them?

S: Well, they live together as a family and take care of their young until they are at least two years old. They’re really friendly with each other. And what I really like is that they even have greeting ceremonies. And they are not at all aggressive and territorial like the Eastern marmots. So their social behavior is so different from Eastern marmots because of the climate where they live? That seems so bizarre.

對應問題:

31. Drag the appropriate description of each marmot species' behavior to the box below the marmot's name. Click on a phrase. Then drag it to the space where it belongs. One of the phrases will not be used.

聽力文本:

Death valley is this desert plane, a dry lake bed in California surrounded by mountains and on the desert floor these huge rocks, some of them hundreds of pounds. And they move…So what’s going on? Theory NO.1 ---Wind?... Um…How can that be? How about wind combined with rain?... There are a few other theories. Maybe the ground vibrates, or maybe the ground itself is shifting, tilting.

例：TPO3 L1, Humming bird (Biology)

聽力文本:

But the problem, well, as natural habitat along these migration routes is developed by humans for housing or agriculture or cleared for raising cattle, for instance, there is less food available for migrating humming birds. Their nesting sites are affected too, the same by the same sorts of human activities. And all of these activities pose a real threat to the humming bird population. So help them survive, we need to preserve their habitats. And one of the concrete ways people have been doing this is by cleaning up polluted habitat areas and then replanting flowers, um, replanting native flowers that humming birds feed on. Promoting ecological tourism is another way to help save their habitat.

聽力文本:

But here’s a little bit about Rose Frantzen’s life anyway. She attended art school, but was told by one of her instructors that she was not good at illustration, that she should go into advertising instead. So she took advertising classes and fine arts classes too, until she was convinced by the head of an advertising agency that her work was really good, that she could be an artist. But of course, it’s not as easy as that, and so Frantzen had to paint other people’s portraits at places like art fairs just to make money to buy paint for her more series of art work. No matter what, she never stopped painting.

對應問題:
