TPO24听力题目(Conversation+Lecture)

　　Conversation 2

　　18. Why does the student go to speak with the professor?

　　"To discuss material that might be on the final exam

　　"To review his answers to the midterm exam

　　"To get information about a class he missed

　　"To find out about the services of the tutoring center

　　19. What does the professor tell the student about the tutoring center? Click on 2 answers

　　"It will have extended hours dying the final-exam period.

　　"It is located in a building near where he works

　　"He can improve his writing skills there.

　　"He can get help with geography there.

　　20. What aspect of the hydrologic cycle is the student confused about?

　　"How the process of evaporation works

　　"How topographical features affect precipitation

　　"How water vapor in the atmosphere becomes rain

　　"How lake water fits into the cycle

　　20. In the conversation, the professor describes the process that causes lake-effect snowstorms. Indicate whether each of the following is a step in the process:

　　"Arctic air blows across a lake and picks up moisture

　　"Cold air temperatures cause lake water to freeze

　　"Frozen lake water cools me air above it

　　"Water vapor condenses and becomes snow

　　"Warm air rises when it reaches the shore

　　22. Why does the professor say this?

　　"To make sure the student knows he'll have to be familiar with topographical features for the final exam

　　"To remind the student of a diagram that she presented in class

　　"To point out the severity of weather conditions near the lakeshore

　　"To reinforce the connection between her example and the student s question

　　Lecture 3 Archaeology (Megafauna in North America)

　　23. What is the lecture mainly about?

　　"Theories about how large animals were able to survive the most recent ice age

　　"Environmental changes that occur following an ice age

　　"Theories about the hunting methods used by early humans in North America

　　"Explanations for the disappearance of large animals in North America

　　24. Why does the professor mention an archaeological site in Southern California?

　　"To present evidence that supports the hunting theory

　　"To present evidence that mammoths migrated southward to avoid cold winters

　　"To point out that mammoth bones are usually found near human debris

　　"To demonstrate that large animals were able to survive in a variety of habitats

　　25. What is the professor's opinion about the Clovis people?

　　"Their excessive hunting of mammoths was responsible for the extinction of these animals

　　"Their lack of tools for processing meat contradicts the hunting theory.

　　"They were less accomplished at hunting mammoths than the hunting theory suggests.

　　"They were probably too afraid of large animals to hunt them.

　　24. According to the climate change theory, how did the climate change at the end of the ice age make it more difficult for large animals to survive? Click on 2 answers

　　"A. By reducing the size of their habitats

　　"B. By forcing them to endure a wider range of temperatures

　　"C. By reducing the variety of food available to them

　　"D. By forcing them to live near humans

　　27. What does the professor imply is one problem with the climate change theory?

　　"Many large animals actually benefitted from the climate change

　　"Large animals had survived previous climate changes

　　"Large animals were probably already near extinction before the climate changed.

　　"New evidence suggests that the climate change was not as extreme as scientists once believed

　　28. The professor mentions a series of computer simulations. What did the simulations suggest?

　　Click on 2 answers

　　"The killing of only a few mammoths could lead to a significant reduction in the mammoth population.

　　"Many mammoths died as the result of an extended drought.

　　"Female mammoths were less able than male mammoths to adapt to climate change

　　"Both hunting and climate change contributed to the extinction of the mammoths

　　Lecture 4 Astronomy (Shield Volcanoes on Venus)

　　29. What is the lecture mainly about?

　　"Conclusions about the surface of Venus drawn from recent observations

　　"The different types of volcanoes that have been found on Venus

　　"Similarities between geologic processes on Venus and on other planets

　　"New methods used to observe the surface of Venus

　　30. How were scientists able to learn new information about Venus' surface?

　　Click on 2 answers

　　"More powerful telescopes allowed astronomers to see more surface details

　　"Satellites were used to get radar images of Venus' surface.

　　"Space modules sent photographs after landing on Venus.

　　"A space probe was able to locate gaps among Venus' clouds

　　30. What differences between volcanoes on Venus and those on Earth does the professor mention?

　　Click on 2 answers

　　"Volcanoes on Venus are mostly shield volcanoes

　　"Volcanoes on Venus emit thicker lava

　　"Many volcanoes on Earth are concentrated in specific zones.

　　"Many volcanoes on Earth show no volcanic activity

　　32. Why does the professor mention the fact that Venus has no surface water?

　　"To give an example of a discovery that was unexpected

　　"To illustrate the consequences of intense volcanic activity

　　"To question a theory about the origin of shield volcanoes

　　"To suggest an explanation for why Venus does not have moving tectonic plates

　　33. According to the professor, what is a possible origin of Venus' clouds?

　　"Gases released as a result of volcanic activity

　　"Chemical reactions caused by high surface temperatures

　　"Bursts of radio energy from the plane's surface

　　"Strong winds that blow dust into the atmosphere

　　34. What is the professor's opinion about the theory that Venus' volcanoes are active?

　　"The theory has recently been proved by direct observation

　　"At least two kinds of evidence support the theory

　　"The data collected so far about the theory are contradictory

　　"New findings have made the theory quite unlikely.
