Part A :

I've brought my notes on our Biology Field Trip to Rocky Bay, Colin,

我已经把我关于岩石湾生物实地考察的笔记带来了,柯林,

so we can work on our report on the research we did together.

所以我们可以致力于我们一起做的研究的报告.

OK. I've got mine too. Let's look at the aims of the trip first.

好的.我也把我的带来了.让我们先看一下旅行的目的.

Right. What did you have?

好的.你的(笔记上)有什么?

I just put something about getting experience of the different sorts of procedures used on a field trip.

我只是写了在实地旅行中获得使用的各种步骤的经验.

But we need something about what causes different organisms to choose particular habitats.

但我们需要一些关于什么原因导致不同的生物体选择特定的栖息地.

I agree. And something about finding out how to protect organisms in danger of dying out?

我同意.还有一些关于如何保护濒临危险的生物,不让它们灭绝.

In our aims?

在我们的目标中吗?

But we weren't really looking at that.

但我们并没有着手这一块.

I suppose not.

我不认为是这样.

OK, now there's the list of equipment we all had to bring on the field trip.

好吧,现在我们有到带去实地考察的设备清单.

What did they tell us to bring a ruler for?

他们叫我们带一把尺子来做什么?

It was something about measuring the slope of the shore,

这是一种测量海岸斜坡的东西,

but of course we didn't need it because we were measuring wind direction, and we'd brought the compass for that...

但我们不需要它,因为我们要测量风向,而且我们也带来了指南针……

But not the piece of string to hold up in the air!

但没有带一根弦来举在空中.

Didn't Mr Blake make a fuss about us leaving that behind.

布莱克先生对我们忘了带这个而大惊小怪?

Yeah. He does go on.

是啊.他确实有点(大惊小怪).

Anyway it was easy to get one from another of the students.

无论如何,这段很容易可以从另一个学生中拿到一个.

Now, the next section's the procedure.

现在,下一部分是步骤.

I sent you the draft of that.

我寄给你了一份草稿.

Yeah. It was clear, but I don¡¯t think we need all these details of what time we left and what time we got back and how we divided up the different research tasks.

是啊.它清楚,但我不认为我们需要所有的这些细节,我们什么时候离开,什么时候我们回来,以及我们如何划分了不同的研究任务.

OK. I'll look at that again.

好的.我再看一下.

Then we have to describe our method of investigation in detail.

那我们得详细描述我们的调查方法.

So let's begin with how we measured wave speed.

所以让我们先从我们如何测量波速.

I was surprised how straightforward that was.

我感到惊讶的是,这是如此简单.

I'd expected us to have some sort of high-tech device, not just stand there and count the number of waves per minute.

我以为我们需要一些高科技的设备,不只是站在那里计算每分钟的波浪数.

Not very precise, but I suppose it was good enough.

不是很精确,但我想这样已经够好了.

But the way we measured the amount of salt was interesting.

但我们测量盐的方法很有趣.

In the water from the rock pools?

在岩石池的水里.

Yeah, I wanted to check the chemicals we used in the lab when we analysed those samples - was it potassium chromate and silver nitrate?

是啊,哦,当我们要分析这些样品的时候,我想检查我们在实验室里用的化学物质--它们是钾铬和硝酸银吗?

That's right.

是的.

You just left that to me.

你只留下那个给我.

And I had to do it while the tide was low, well that was OK, but the place I started it from was down on the beach,

我不得不去做它,而潮汐很低,好吧,那样也可以,但我是从在海滩上开始的,

then I realized I should have gone up higher to get better visibility, so I had to start all over again.

然后我意识到我应该到更高的地方去获得更好的能见度,所以我不得不从头开始.

But at least I'd got the squared paper or I'd have had problems drawing it all to scale.

但至少我有方格纸,不然我在按照规格比例绘画上就会有问题.

Yes. It looks good. We could get a map of the region off the internet and see if we need to make any changes.

是的.看起来不错.我们可以从互联网上获取地区的地图,看看我们是否需要做出任何改变.

I had a look but I couldn't find anything.

我看了一眼,但我找不到任何东西.

But you took some pictures, didn't you?

但你拍了一些照片,是不是?

Yeah. I'll email you them if you want.

是啊.如果你想要的话,我会给你发电子邮件的.

OK. I'll make my amendments using those, then I can scan it into our report. Great.

好的.我会用这些来做修正,然后我可以扫描到我们的报告里.太棒了.

Part B :

So for the highest area...

所以对于最高的地区……

...the splash zone?

…飞溅区.

Yeah, we found mostly those tiny shellfish that have strong hard shells that act as protection.

是的,我们发现大多是那些很小的贝壳,有很强的坚硬外壳,作为保护.

But not from other organisms that might eat them, predators?

难道不用来要保护他们不遭受其他那些可能吃他们生物,那些捕食者的侵害吗?

No, that's not the main danger for them.

不,这不是他们的主要危险.

But the shells prevent them from drying out because they're in the open air for most of the time.

但这些壳防止他们变干,因为他们大部分时间暴露在露天(环境下).

Right. And since they're exposed, they need to be able to find some sort of shelter, or cover themselves up, so they don't get too hot.

对.既然他们被暴露了,他们需要找到一种庇护,或者掩盖自己,所以他们不会太热了.

Then in the middle and lower zones, nearer the sea, we need to discuss the effects of wave action...

然后在中、下区,靠近大海,我们需要讨论波浪作用的影响……

Yes, and how organisms develop structures to prevent themselves from being swept away, or even destroyed by being smashed against the rocks.

是的,生物如何发展结构,以防止自己被冲走,甚至被破坏的岩石粉碎.

I haven't done anything on the geological changes.

我没有做任何关于地质变化的事情.

5753 106

5753 106

I don't know what to put for that.

我不知道该如何描述那个.

No, we weren't concentrating on that.

不,我们并没有关注那个(方面)。

Maybe we need to find some websites.

也许我们需要找到一些网站.

Good idea. I've got the lecture notes from Mr Blake's geology course, but they're too general.

好主意.我有布莱克先生的地质学课程中的讲义,但它们太笼统了.

But we could ask him which books on our Reading List might be most helpful.

但我们可以问他书单上什么书对我们可能是最有帮助的.

Right. OK, now I did a draft of the section of sources of possible error in our research, but I don't know if you agree.

对.好的,现在我做了可能出现的错误来源部分的草案,但我不知道你是否同意.

For example, the size of the sample, and whether it's big enough to make any general conclusions from.

例如,样本的大小,以及是否足够大到可以从中得出一般性结论.

But I thought actually we did have quite a big sample.

但我认为事实上我们有相当大的样本.

We did. And our general method of observation seemed quite reliable.

我们的确有.我们的观察方法似乎相当可靠.

But we might not be all that accurate as far as the actual numbers go.

但我们不可能和真实数字一样精确.

Yeah, we might have missed some organisms - if they were hiding under a rock, for example.

是的,我们可能会错过一些生物--例如,如果他们躲在岩石下面.

I wasn't sure about the way we described their habitats.

我不确定我们描述他们的栖息地的方式.

I decided it was probably OK.

我觉得可能是没问题的.

Yeah, and the descriptions we gave of the smaller organisms, they weren't very detailed, but they were adequate in this context.

是的,我们给的小生物体的描述不是很详细,但在这方面,应该足够的.

I'm not sure we identified all the species correctly though.

我不确定我们是否正确地识别了所有的物种.

OK, we'd better mention that. Now, how...

好的,我们最好提一下这个.现在,如何…
