Questions 34-38 Listen as a student asks a question in a physics lecture.
It’s important that you all understand that quartz heaters operate on a totally different principle than common convection heaters. Yes?
Could you give us an example of a convection heater?
Ok. But first you tell me what convection means?
Um, well, you said in the last class, I think, that convection is the transference of heat by a liquid or a gas.
Right, A heater is using convection when it warms the air in a room. And the air in turn warms the people and objects in the room. A hot-water radiator, a stove and a forced air furnace are all convection heaters. A quartz heater on the other hand, heats the objects and people in a room without heating the air. It does this by producing radiation heat that travels like light waves. When the quartz crystal in a heater vibrates at a particular frequency, its energy is turned into infrared radiation. The radiation is then directed at objects by means of a reflector. If that’s clear, let’s move on to how room design can affect heating efficiency.
34. What is the main topic of the discussion?
35. What had the instructor probably been discussing in the previous class?
36. What does the instructor ask the student?
37. According to the instructor, how was the quartz heater different from other types of heaters?
38. What is the purpose of a reflector on a quartz heater?
Questions 39-42 Listen to university official talk about a job placement office.
As a result of rising university costs, many students are finding it necessary to take on part-time job. To make finding those jobs easier, the placement services put together a listing of what’s available locally. For some students, these part-time jobs could lead to full time work after graduation, as they may offer experience in their own field, be that finance, marketing or even management. For example, National Saving Bank offers a work on a half time basis. That’s twenty hours a week. Retail stores and restaurants have positions requiring fewer hours. Even less time is expected of those providing child-care. We have a number of families registered with us who were looking for baby sitters for as few as 4 hours a week. For students who prefer outdoor work, there are seasonal positions right on campus, working with the gardening and landscaping teams.
These often require the most time and are the least flexible in terms of scheduling. To see a complete list of these and other available jobs, including the salary offered and the hours required, stop by our office. Oh, and be sure to bring a resume with you. When you find something that interests you, we’ll put you in touch with the person offering it. In addition, our counselors will give you hints about successful interviewing.
39. What is the purpose of the talk?
40. What should students bring with them to the office?
41. What will the counselors at the office help students do?
42. What do all of the jobs have in common?
Questions 43-46 Listen to a professor talking about United States art history.
In this century, photographs have been really important for teaching art history. I’ll show you what I mean in a moment with some photographs taken by Peter and Paul Julie. The work of these two photographers has been a very useful source for studying the art produced in the United States from 1896 to the present. Peter and Paul Julie were not artists. But they were a regular part of the New York art theme. They took over a hundred thousand photographs which document the lives and work of thousands of artists. Peter Julie is known as a pioneer in this field of art photography. Georgia O’keefe and other famous artists sought him out to take pictures of their work. His specialty was photographing paintings. His son Paul photographed sculptures.
Some of their most important photos are the ones of works of art that have since been destroyed. One example is a photo that we’ll look at today. Would someone get the lights please? Thanks. This slide is from a photograph of a painting by Edward Hopper called Corn Belt city. The painting was exhibited only two or three times before it was destroyed in a fire. Without the Julie photograph, no visual record of the work would exist.
Although the Julies mostly photographed the work of painters and sculptors, they also occasionally photographed architectural subjects. They did quite a few photos of buildings by John Russell Pope. And we’re going to look at one of those next.
43. What does the professor mainly discuss?
44. What did Peter Julie do for Georgia O’keefe?
45. According to the professor, what was the specialty of Peter Julie’s son, Paul?
46. Why does the professor mention the photograph of the painting Corn Belt city?
Questions 47-50 Listen to part of radio report about a scientific advance.
Do you know that vegetables can be tricked into growing in climates they are not accustomed to? Cool climates vegetables like asparagus are now able to be grown in places as hot as Hawaii. In Hawaii, marine engineers have been able to actually convince such vegetables that they are living in cooler climates. That way they grow faster and taste better. What these engineers have been using is very simply cold seawater.
How do they use it? They placed pipes in the soil and the cold water flowing through them cools the earth. This stimulates plant growth and enables gardeners in tropical climates to grow crops from cooler climates. Also, some of these pipes are exposed to the air and they condense moisture and thus irrigate the gardens. What is especially appealing about this process is that nothing damaging to the natural environment is being used.
Another innovative use for cold ocean water is to cool buildings. Engineers believe that, for example, the entire west coast of the United States could be air-conditioned using seawater. We’ll be back to discuss that possibility after this commercial message.
47. What is the report mainly about?
48. What does the new system enable farmers to do?
49. How were the pipes used in Hawaii?
50. Why does the speaker mention air-conditioning?
