Forensic linguistics

文章大意

雅思听力Part3对话中，学生Rob和Jen讨论司法语言学项目，先定义司法语言学为分析语言以破案，再聚焦声纹鉴定：听嫌疑人录音、用声谱仪分析、面对面采访比对声音，并提到录音不清、口音变化等测试难点。

题目与答案

1. 21 What do the students agree about defining forensic linguistics?
   • The dictionary definition was not very useful.
   • They could provide an example of the kind of work involved.
   • They should read about the subject to see how it is described.

   答案：They could provide an example of the kind of work involved.

   原文定位：Sure. The first thing we have to do is define forensic linguistics. I thought we could say something like, "Linguistics involves the analysis of language, and forensic refers to using scientific techniques to solve crimes. So forensic linguistics involves analyzing people's use of language to find out whether they've committed a crime." What do you think of that as a definition;Sounds okay. I looked it up in my dictionary, and I got something similar;Then we can add something about what forensic linguists actually do to back it up. You know, like analyzing documents to find out who wrote them;Good point. Let's do that

   同义替换：「provide an example of the kind of work involved」↔「add something about what forensic linguists actually do to back it up. You know, like analyzing documents to find out who wrote them」，「agree」↔「Good point. Let's do that」

2. 22 Jen thinks will be difficult to analyze the voice recording because
   • it is not of good quality.
   • the accent is difficult understand.
   • she doesn`t know if the speaker is male of female.

   答案：it is not of good quality.

   原文定位：Well, I've already listened to the recording, and I can't even tell if it's a man or a woman. But I guess that doesn't matter. The accent's a local one, though I'm not sure how that will affect anything. Where we're really going to get in trouble is that the recording is very unclear. I'm sure they've done that to test us

   同义替换：「difficult to analyze the voice recording」↔「Where we're really going to get in trouble is that」，「not of good quality」↔「very unclear」

3. 23 Why does Jen think that the “suspect” might vary their voice patterns?
   • because they`re being recorded.
   • because they`ve been told to.
   • because they fell uncomfortable about their accent.

   答案：because they`ve been told to.

   原文定位：You can often tell even when they've got a cold, it's the same person, but they might do something like speaking with another accent because the tutor suggests they do that just to test us

   同义替换：「vary their voice patterns」↔「speaking with another accent」，「been told to」↔「suggests they do that」

4. 24 What does Rob think about Jen`s approach to study?
   • She worries too much about her ability.
   • She often ignores the most important issues.
   • She has trouble getting started.

   答案：She worries too much about her ability.

   原文定位：So let's get on with it then. Oh, and don't start your usual self-doubt about whether you can do the work or not. You usually do okay in the end

   同义替换：「worries too much about her ability」↔「don't start your usual self-doubt about whether you can do the work or not」

5. 25-26 Which TWO books do Jen and Rob decide to get from the library?
   • Voice Identification
   • Modern Forensic Techniques
   • Language and Crime
   • Forensics Today
   • Research Methods in Forensic Linguistics

   答案：Voice Identification,Research Methods in Forensic Linguistics

   原文定位：Okay. I've already looked at Forensics Today, and it didn't say much about voice identification, so we needn't bother with that one. Language and Crime looks a bit more promising, doesn't it? I've got that out of the library already, so we don't need to worry about borrowing that;Research Methods in Forensic Linguistics, I guess we ought to borrow that, and Voice Identification will be a useful one. I'll borrow that from our classmate, George. He won't need it for his project. But we should get out Modern Forensic Techniques. We need all the help we can get on that subject

   同义替换：「decide to get from」↔「ought to borrow that」

6. 27-28 Which TWO practical considerations are both Jen and Rob concerned about?
   • how much time they have for writing up the project
   • being able to do enough research
   • which BD using recording equipment
   • only speaking to the “suspect” once
   • how easy it will be to contact the “suspect”

   答案：which BD using recording equipment,how much time they have for writing up the project

   原文定位：Okay, that's that sorted out. Now onto the practical stuff. I'm not sure about how we're going to record the voices. I'm not too good on the technical side of things;Me neither. We better work out what we're doing. At least we get more than one opportunity to speak to the person playing the suspect. I just hope whoever it is won't make the task too tricky;I'm sure they won't be too hard on us. And as long as we do our research properly, it shouldn't be too hard to do the rest of it. I'm more worried about fitting in the writing up;I know. We've got loads of other assignments to finish as well

   同义替换：「how much time they have for writing up the project」↔「We've got loads of other assignments to finish as well」，「concerned about」↔「more worried about」

7. 29-30 Which TWO sections of the project will Rob write alone?
   • Methodology
   • Literature review
   • Introduction
   • Analysis
   • Discussion and conclusions

   答案：Introduction,Discussion and conclusions

   原文定位：Now, Rob, let's decide how we're going to split the writing between us. Are you any good at introductions? They always seem to let me down;Okay, leave that to me. Are you okay to do the literature review then;Maybe we should split that part. I don't mind writing the methodology section if you feel comfortable doing the discussion and conclusions;Okay. And we can do the analysis between us as well. Great. Let's get started

   同义替换：「write alone」↔「leave that to me」
