SECTION B INTERVIEW
Directions: In this section you will hear everything ONCE ONLY. Listen carefully and then answer the questions that follow. Questions 1 to 5 are based on an interview. At the end of the interview you will be given 10 seconds to answer each of the following five questions.
Now listen to the interview.
听力原文:ALLEN: Some scientists of UFOs are issuing a report that may heat up speculation about this always-lively topic. In the first independent review of UFO phenomena in more than 30 years, a nine-member group of scientists says physical evidence linked to some sightings deserves additional scientific study.
The physicist who headed up that panel is Peter Sturrock, who joins me now from Stanford, California. Thanks for joining us, sir.
STURROCK: You're welcome.
ALLEN: Well, tell us about the sightings that you believe need further examination?
STURROCK: Well, I'm not presenting my belief. I'm presenting the assessment of a panel of scientist who met with a group of eight investigators. The investigators were asked to present whatever physical evidence they found in the course of their research. And the only question asked of the panel was that, do you believe that further study of this kind of case, this kind of evidence, might eventually lead to answers to the problem of understanding the cause or causes of UFO reports? And the panel felt, yes, this would be a premising line of research for the future.
ALLEN: So can you give us an example of a particular sighting they may examine further?
STURROCK: Well, there were many examples given, ranging from photographic evidence through radar, through ground traces. But the panel, in particular, is interested in cases with more than one kind of physical evidence. And one of those occurred in France in 1981. It is, unfortunately, a single-witness case. But the witness, who was working in his garden, heard a whistling sound, saw a strange object land on his terrain and then leave.
In France, they have an official data collection and organization, organized through the French space agency, CNES. So the next day, the Jondomery(ph) (gendarmerie i. e. , ed. ) came out and took photographs, took samples of the plants. A little later, scientist from the space agency came out, took further samples, further photographs, took soll samples, and took samples of the vegetation, which were alfalfa plants. And they found there were deep marks in the soil that would have taken about l ton to produce, and the vegetation has strange biochemical changes, which could perhaps be caused by micro-radiation; they didn't know what.
But here is one case with only a single witness and two kinds of physical evidence. The panel really urges a search for cases with many witnesses and more than one kind of physical evidence.
ALLEN: I believe I read that you have said that you believe there should be more emphasis placed on the physical evidence as opposed to witness testimony.
STURROCK: You need both, you need both. You have to have strong witness testimony, and you have to have physical evidence that we analyze in the laboratory,
And these are really quite different kinds of activities. And it probably would be good ff different people, or different teams, were involved in the two types of research.
It may take an official organization, as in France, to collect the data that can then be provided to university scientist or other scientist to analyze the data.
ALLEN: You've also said that this field of UFO study is in a very unsatisfactory state of ignorance and confusion. Why do you think that is, when there seems to be something that so many people have an interest in?
STURROCK: Well, I think basically it's because there has been no sponsored research in this area. Almost all scientific research in the nation is sponsored by an agency or supported by the institution, like a corporation or an uni
