托福TPO/Official 75 Con2听力原答案解析-音频翻译【新东方在线】

旁白：听一段学生和她的导师之间的对话。

Narrator: Listen to a conversation between a student and her advisor.

导师：那么，费莉西亚，你能告诉我为什么你的分子生物学课程还没有成绩吗？

Advisor: So Felicia, can you tell me why you haven't received a grade yet for your molecular biology course?

学生：嗯，说来话长，不过，嗯，我的RP73实验搞砸了。

Student: Well, it's a long story, but, well, my RP 73 experiment got messed up.

Advisor: I wanna run that by me again please.

学生：对不起。嗯，我当时正在做一个蛋白质检测。

Student: I'm sorry. Um, I was running a...a protein assay.

学生：嗯，这就像是一个实验，用来确定这种RP73蛋白质是否具有潜在的治疗价值。

Student: Uh, it's like an experiment to determine whether this RP 73 protein could have potential therapeutic value.

导师：哦，比如应用在医疗领域。

Advisor: Oh, like be applied in a medical context.

学生：嗯，大致就是这个想法，至少是有这样的希望。但要做到这一点，首先你得分离出这种蛋白质，

Student: Well, that's the general idea, the hope anyway. But in order to do that, you first have to isolate the protein,

你知道的，要生产出足够纯净的形式用于实验，而且还得生产出足够的量。

you know, produce it in a pure enough form for the experiment and you have to produce enough of it also.

导师：好的。我想我开始明白了。嗯，

Advisor: Okay. I think I'm starting to understand. Well,

学生：当你实际生产这种蛋白质时，这需要很长时间。通常有一个过夜的步骤，需要在培养箱里放16个小时，为了什么呢？

Student: When you're actually producing the protein, that takes a long time. Usually there's an overnight step where you need 16 hours in the incubator to what

保持足够高的温度，而就在这个时候，事情开始变得糟糕了，

keep it at a warm enough temperature and while that's when things started to go downhill,

Advisor: Oh, you didn't wait long enough?

学生：实际上，我等得太久了，蛋白质降解了，你知道的，在里面有点分解了。

Student:Actually, I waited too long and the protein got degraded, you know, kind of disintegrate in there.

我本该在周六过来终止培养的，但那天先是我的车发动不起来。

I needed to come in to stop the incubation on Saturday, but it was one of those days first my car wouldn't start.

我通常开车去，因为实验室有点远，对吧?

I usually drive cuz the lab is kind of far,right？

所以我试着坐公交车，但我不知道周末几乎没什么公交车。

So I tried taking the bus but like I had no idea that there's hardly any buses on the weekend.

所以当时我真的很恐慌，我想我得打电话求助，你知道的，打电话到实验室，让别人把我的实验样本从培养箱里拿出来放进冰箱。

So now I'm really panicking and I think I'll try to phone it in, you know, call the lab and ask someone to take my experiment out of the incubator and stick it in the freezer.

但当然，那里没人，因为是周末。

But of course no one's there cuz it's the weekend.

导师：哦，那有没有办法挽救这个实验呢？

Advisor: Oh, and was there no way to salvage the experiment?

学生：嗯？我终于赶到实验室的时候已经差不多一点了，那时候蛋白质已经降解了。基本上没法用了。

Student: Uhuh? It was like one o'clock when I finally made it to the lab and by that time the protein had degraded. It was basically unusable.

导师：我明白了。但你就不能重新开始吗？

Advisor: I see. But couldn't you just start over?

Student：是啊，当然可以。我也确实重新开始了。嗯，通常这种事在实验室里经常发生，通常没什么大不了的。

Student: Yeah, of course. And I did. Well normally this kind of stuff happens in the lab all the time and it's usually no big deal.

但这个实验离学期末太近了。时间太紧张了。

But this experiment was too close to the end of the semester. The timing was too tight.

我的意思是，我现在正在重新做，但与此同时，学期结束了，成绩必须提交，这就是我最终得到一个“未完成”的原因。

I mean, I'm writing it again as we speak, but in the meantime, the semester's over and the grades had to be turned in and that's how I ended up with an incomplete.

导师：现在我明白了。那你预计能很快完成吗？

Advisor: Now I understand. So you expect you'll be able to complete it soon?

学生：嗯，我可能还需要几个星期。

Student: Well, I'll probably need a couple more weeks.

我跟我的生物学教授谈过了，她不介意我在假期里使用实验室。

I spoke to my biology professor and she doesn't mind that I'm using the lab over the break.

你知道的，实验室从不关门。总是有事情在进行。

You know, the lab never closes. There's always something going on.

导师：（笑）是吗。嗯，我虽然是学人文的，但我对科学也了解不少，知道这一点。

Advisor: <laugh>? Yes. Well, I may be in the humanities, but I know enough about the sciences to know that much.

好的。那我就等着收到成绩了。

All right. So I'll be expecting to receive a grade.

What does the student try to explain to her adviser?

Why does the student want to study the RP73 protein?

According to the student, under what circumstance might her experiment have been saved?

From the student’s comments, what can be inferred about the molecular biology professor?
