　　[00:24.81]SECTION A MINI-LECTURE

　　[00:26.67]In this section,

　　[00:28.31]you will hear a mini-lecture.

　　[00:30.06]You will hear the lecture ONCE ONLY.

　　[00:32.47]While listening, take notes on the important points.

　　[00:35.97]Your notes will not be marked,

　　[00:38.04]but you will need them to complete a gap-filling task after the mini-lecture.

　　[00:42.31]When the lecture is over,

　　[00:44.83]you’ll be given two minutes to check your notes,

　　[00:46.91]and another 10 minutes to complete the gap-filling task.

　　[00:49.86]Now listen to the mini-lecture.

　　[00:52.48]Seven Types of Evidence

　　[00:55.54]Good morning.

　　[00:56.75]Today we will talk about how to use evidence in writing.

　　[01:01.02]In much of your college writing,

　　[01:03.42]you will try to persuade your readers to see things your way.

　　[01:07.79]Without good evidence to support your ideas,

　　[01:11.29]you will hardly persuade anyone of anything.

　　[01:14.14]So today we’ll look at seven kinds of evidence

　　[01:18.62]that are widely used in argumentative writing.

　　[01:21.90]The first type of evidence is expert testimony.

　　[01:26.38]An expert is someone who has special skill and knowledge

　　[01:30.65]based on careful study and wide experience in a certain area.

　　[01:35.47]More than that, an expert has tested his or her skill

　　[01:40.06]and knowledge in a public forum.

　　[01:41.92]Once your opinion is firm,

　　[01:45.20]you can use expert testimony to support it.

　　[01:48.05]To use expert testimony wisely,

　　[01:50.56]you need to be both respectful and critical.

　　[01:54.06]You will need to differentiate among three kinds of evidence

　　[01:58.32]that experts provide:

　　[01:59.96]facts, informed opinions, and speculations.

　　[02:03.90]Generally, you can use facts and informed opinions,

　　[02:07.95]but must be cautious with speculations.

　　[02:11.23]This is because speculations are just what one person thinks is plausible,

　　[02:17.47]so they should be treated as something that could be true.

　　[02:21.18]The second type of evidence is statistics.

　　[02:25.34]Statistics are numerical data gathered and tabulated to yield information.

　　[02:31.03]Whether they are raw data

　　[02:33.76]or translated into charts and figures,

　　[02:36.39]numbers are powerful evidence.

　　[02:38.79]If they are properly used,

　　[02:40.76]data can prove a claim rapidly and conclusively.

　　[02:44.92]When a survey shows that 95 per cent of senior students

　　[02:49.95]are satisfied with the courses they have taken at a university,

　　[02:54.21]we can persuade readers that the university is a good one.

　　[02:58.04]But you must be careful with numbers.

　　[03:01.11]Only when the data are valid,

　　[03:03.62]accurate and up to date can they really support your point.

　　[03:07.77]So when you want to use data,

　　[03:10.29]examine carefully before putting them down in your article.

　　[03:13.79]Next comes the third evidence, examples.

　　[03:18.17]Every day you use examples as evidence for your claims.

　　[03:22.65]You might write to your parents,

　　[03:24.95]“Sorry I haven’t written much

　　[03:26.92]but I’ve been very busy.

　　[03:28.66]I spent last week in the library,

　　[03:30.85]bent over the books studying for two midterms.”

　　[03:34.24]In this case, you establish your claim and back it up with a specific example.

　　[03:40.26]Examples serve three purposes.

　　[03:43.98]First, they clarify meaning.

　　[03:46.49]Your parents may not know exactly

　　[03:48.90]what you mean by busy until you show them.

　　[03:52.07]Second, examples demonstrate why,

　　[03:55.46]at least in one instance,

　　[03:57.10]you are justified in making your claim.

　　[03:59.95]Studying for two midterms does sound like being busy.

　　[04:04.65]Third, examples make for entertaining reading.

　　[04:08.48]Abstractions are dry.

　　[04:10.89]Claiming that you are busy isn’t very interesting.

　　[04:14.16]But the image of you bent intently over a book probably pleases your parents,

　　[04:20.62]who may now forgive you for not writing.

　　[04:23.13]The fourth type of evidence is personal experience.

　　[04:27.62]If we actually experience something directly,

　　[04:31.01]we don’t need experts or statistics to back us up.

　　[04:34.95]Although we know that our experience is not totally reliable,

　　[04:39.65]we trust our senses and our ability to understand our personal experience.

　　[04:44.90]And in some cases,

　　[04:47.42]our own experience can persuade readers to accept our statement.

　　[04:51.57]In complex matters,

　　[04:53.98]however, be aware of jumping to conclusions based on limited personal experience.

　　[04:59.77]Your experience may help to explain,

　　[05:03.05]but it cannot prove a more general thesis.

　　[05:06.56]Knowing someone who cheats on her income tax does not prove

　　[05:11.04]that the problem with income tax cheaters is pervasive.

　　[05:14.98]Even if you know five or ten or twenty cheaters,

　　[05:19.24]all that proves is that you are unlucky in your acquaintances.

　　[05:23.73]For such a complex subject, you need more than personal experience.

　　[05:28.43]You need statistics and expert interpretation.

　　[05:31.93]Analogy is the fifth type of evidence on our list.

　　[05:36.63]An analogy is a comparison of apparently dissimilar things,

　　[05:41.67]and its purpose is to illuminate one thing

　　[05:44.95]by showing how it is like and not like the other.

　　[05:48.55]If well used,

　　[05:50.53]an analogy can make an abstract, unfamiliar topic easy to understand.

　　[05:55.67]For example, if a writer wants to directly persuade readers

　　[06:00.58]that it is our work that determines our social role,

　　[06:04.08]he would face a tough task.

　　[06:06.05]But analogy can help him out.

　　[06:08.68]Here is his analogy:

　　[06:10.43]Human beings in a society are like the bees in a hive.

　　[06:15.35]Each person’s identity is determined by his or her place in the overall system.

　　[06:21.81]Like drones,no one has any identity but the work he or she does.

　　[06:27.82]And if one doesn’t work,

　　[06:29.68]he will be kicked out of the society just like a drone out of the hive.

　　[06:34.60]However, analogies should be used with caution.

　　[06:39.08]To the extent that analogies make a point easy to see,

　　[06:43.02]they are evidence.

　　[06:44.56]But they don’t prove the point

　　[06:46.89]—they can never be sufficient evidence for a complex idea.

　　[06:50.82]After analogy, let’s look at the next type of evidence, known facts.

　　[06:57.17]When writing, you can safely assume

　　[07:00.01]that you and your readers share a vast body of facts and beliefs.

　　[07:04.72]You don’t need to point out Columbus arrived in America in 1492,

　　[07:10.51]or that China has a history as long as 5,000 years.

　　[07:14.78]But these facts can be used as evidence in your writing.

　　[07:19.48]The last type of evidence we usually use is logic and reasoning.

　　[07:24.08]In some cases, we use them because we can’t find any other factual evidence.

　　[07:29.88]And in some cases where we can find factual evidence,

　　[07:33.37]reasoning can make our argument more persuasive.

　　[07:37.09]People in China believe

　　[07:39.21]that good argument should appeal to both sense and sensibility,

　　[07:43.80]which means that both factual evidence and reasoning are necessary.

　　[07:48.29]OK, these are the seven types of evidence.

　　[07:52.45]Before we end today’s lecture,

　　[07:55.07]I would talk about three criteria for good evidence.

　　[07:58.68]First, good evidence should be relevant.

　　[08:01.52]It should speak directly to the point.

　　[08:04.04]You should select particular evidence because it supports the point,

　　[08:08.31]not because it is novel or comic.

　　[08:11.48]Second, good evidence should be representative.

　　[08:15.52]It should represent its source or the situation it describes.

　　[08:19.79]Last, good evidence should be accurate.

　　[08:23.29]It is the writer’s duty to ensure the accuracy of the evidence.

　　[08:28.21]In order to do this, you must check the evidence carefully,

　　[08:32.91]and present it in your writing carefully.

　　[08:35.32]Well, with that, we will end today’s lecture.

　　[08:39.04]We hope that you now understand evidence better,

　　[08:42.10]and we look forward to seeing well-supported articles

　　[08:45.39]from you in the future.
