[00:19.04]Exercise 1

[00:22.72]Directions:

[00:26.35]Listen to the dialogue

[00:30.13]and choose the best answer to each of the questions you hear on the tape.

[00:36.54]Part 1

[00:39.71]Mom:Well, there are no ifs, ands, and buts about it.

[00:45.29]Anna is completely at home with all this technology.

[00:51.26]Dad:Isn't it great? She doesn't have the fear of technology that so many of us have.

[00:59.54]It's amazing to think that her generation has grown up with VCRs, answering machines

[01:09.44]cordless phones, computer games... They take all that stuff for granted.

[01:17.90]That's for sure.To think there are kids her age who have never changed a TV channel

[01:26.36]without a remote control! Can you imagine?

[01:32.38]Dad:I'm sure you're right. Hey-remember our old computer?

[01:39.79]Mom:How could I forget it? I don't ever want to see that old dinosaur 1 again.

[01:48.00]Dad:Oh, come on.

[01:52.07]Mom:Really. It made me so frustrated 2.

[01:57.94]Dad:Well, it's true that new computers are much, much better than the old ones.

[02:06.47]But still, it's hard for me to learn programs

[02:13.34]Mom:I know what you mean. You know,

[02:18.10]I've been thinking that maybe we should take an evening class.

[02:24.68]What do you think? We could get a babysitter.

[02:29.44]Dad:Wow...

[02:32.96]I'm really glad to hear you say that because I've thought a lot about taking a class

[02:42.00]but I've always dragged my feet. I don't know why, really.

[02:49.38]Part 2  At home after the first computer class

[02:55.25]Mom:Look at you! You're really working hard at that computer!

[03:01.98]Dad:Nothing could tear me away. You know, if it weren't for our class,

[03:10.80]I'd be in a bind 3 right now trying to figure out what to do.

[03:17.03]But I'm doing OK. The class really helps.

[03:22.39]Mom:That's the truth. I prefer a teacher to an instruction manual.

[03:29.34]Hey-did I tell you that I want to get a modem 4?

[03:35.06]I want to get online. Don't you think we've held off long enough?

[03:41.80]I want to have e-mail.

[03:45.65]Dad:That teacher sure won you over.

[03:50.44]A few months ago you didn't even know what e-mail was!

[03:57.17]Mom:Well, I have to admit, this whole world of computers is growing on me.

[04:04.66]Dad:Sounds like you're apt to go back to school

[04:10.38]and get some sort of degree in computers.

[04:17.08]Mom:You never know...

[04:20.68]1)What are the two people talking about?

[04:27.19]2)What is the probable relationship between the two speakers?

[04:34.43]3)What brought about a great change in the two speakers' attitude towards computers?

[05:39.95]Listening 2

[05:43.33]Exercise 1

[05:46.68]Directions:

[05:50.17]Listen to the talk

[05:53.59]and choose the best answer to complete each of the following sentences.

[05:59.57]Why Scientific Research?

[06:03.56]My favorite question, lately, is why scientific research?

[06:09.94]The most basic answer is because I want to contribute something to the society

[06:16.38]that I have been taking from all my life,

[06:21.31]and I want to help animals somehow. But then the answers become the questions.

[06:28.76]What could I possibly contribute, and how will my research help animals?

[06:35.21]I had an experience last spring where I was involved in a research project

[06:41.76]in which we were trying to determine more about gut 5 size in lacating voles

[06:48.46]Of course, I was really excited to be participating in something like this

[06:55.01]that could possibly result in a publication.

[06:59.87]We all know how good it looks for an undergraduate to have a publication.

[07:05.38]Anyway everything went along very well

[07:10.42]until I realized that I was going to have to kill about

[07:15.35]20 female voles and their pups.

[07:19.34]Every time I had to kill an animal, I felt the tears burning in my eyes.

[07:26.08]But I had to fight them back

[07:29.60]because scientists don't cry about those silly kinds of things.

[07:35.00]After all, we're doing SCIENCE here! Well,

[07:40.94]I managed to get through the experiment, and, yes,

[07:45.88]my name will be on that publication, but the questions keep puzzling me.

[07:52.46]Was I helping 6 animals

[07:55.67]or just killing them to obtain data we could use in our publication
