I would like to tell you how the Argus computerised photography system has helped marine researchers.
2
Then I shall talk a bit about sand collecting.
3
Well, Argus is the system Dr. Rob Holman developed
4
when he was working at a research pier on the coast of North Carolina about 20 years ago.
5
This pier stretches out over the water and it's the longest research pier in the world, with an observation tower on the end of it.
6
The researchers there make precise measurements of how the sand moves about under the waves,
7
This research is critical to the study of beach erosion in places where the coastline is being worn away.
8
The Argus system helps to solve the difficulties encountered by these researchers.
9
The system correlates the data from under the water with what Dr Holman gets from his fixed camera,
10
which is mounted above the water on the pier and uses time -lapse photography.
11
Some of Dr. Holman's results have changed the way people understand how sand moves.
12
To quote S.
13
Jeffries Williams, a coastal geologist with the United States Geological Survey, the system is "a critical piece of new technology."
14
And the Argus system allows us to quantify
15
and document visually the changes to the coast on a variety of different time frames.
16
A lot of these take place when there is a storm, or at other times when it is difficult to have people out on the beach making observations and taking measurements.
17
Up to now, Argus installations have been installed in places in Oregon, California, Hawaii, England, the Netherlands,
18
Australia, New Zealand, Spain, Italy and Brazil, as well as in North Carolina.
19
Now, I'd like to introduce Dr. Holman's sand collection.
20
He started collecting sand in the 1980s and he still collects it now, even though he has around a thousand samples.
21
They come from his travels and from geologists and amateurs all over the world.
22
and the collection includes sand from each continent, including Antarctica.
23
People send him sand in envelopes, plastic bags, paper towels and all sorts.
24
Each is stored in a glass jar, which Dr. Holman labels by latitude and longitude of its origin.
25
as well as he can work them out.
26
Sometimes the information is a bit sketchy.
27
Anyway, it's mainly geology students at the university who study his collection.
28
and they can learn a lot from it.
29
For instance, one set of tubes displays sand from the east coast of the US,
30
so you can see that the sand gets lighter and finer from north to south.
31
By the time a grain of sand eventually washes up on a beach in Florida, at the southern end of that journey, it has been battered by waves for a long time.
32
So the grains are fine and rounded, because most of the time sand is not stationary on the beach.
33
OK, so if you'd like to collect sand and maybe even send some to Dr. Holman, how should you go about it?
34
Well, the list of equipment is very short and easy to find, but you should keep a supply when you're travelling,
35
as you never know when you'll come across an interesting sand sample.
36
One really handy thing for digging sand, especially if it's hard or frozen, is a spoon.
37
"'It's perfect for that.' If you're travelling by air, it'll have to be plastic, but metal is preferable, as plastic tends to break.
38
You need something to put the samples in that is damp proof and easy to carry.
39
You can just use plastic bags, but you need to record the location and date on the bag, so you must also have a permanent marker with you,
40
because you can never assume you will remember where you gathered a sample from later on, And you don't want it to rub off before you get home.
41
And that's about all you need in the field to collect sound.
42
When you get home, your samples should be logged in a notebook or computer.
43
You need to note the location
44
and be really specific as to exactly whereabouts on the beach you gathered your sample: low tide mark,
45
under cliff area, etc. Then you store your sample.
46
You want to keep everything in good condition and avoid contamination.
47
So first you make absolutely sure that each sample is perfectly dry You don't need any complicated apparatus for this.
48
You can just air it out on layers of newspaper, which is suitably absorbent.
49
Most people find that's the best way.
50
Then, lastly, but this is really important, before there can be any chance of confusing this later sample with another,
51
you put it in a clean small bag or a jar and you must stick an identification label on straight away.
52
Some people put one inside as well, in case the outer label falls off, but that's up to you.
53
Well, that's about all you need to know to get started as a sand collector.
54
Any questions?
55
That is the end of section 4.

练习建议
在进行英语口语练习时，建议您使用shadow speech技巧进行跟读。观看视频时，注意主播的语速和语调，并尝试模仿。适应视频的快慢节奏可以帮助您提升英语口语练习能力。以下是一些具体的练习建议：
- 在播放视频时，暂停并反复聆听关键句子，尝试准确模仿发音和语调，这是shadow speaks技术的核心。
- 使用shadow speak来跟读每段介绍，集中注意力在语句的重音和停顿上。
- 可以选择在舒适的环境中练习，加大语音练习的时长，逐步增加发音的流利度。
- 录制自己的朗读，回放并与原视频对比，找出差距并加以改正。
通过这些方法，您将能够更有效地提高自己的英语口语能力和自信心。在进行练习时，保持积极的态度，并享受学习的过程！
什么是跟读法？
跟读法 (Shadowing) 是一种有科学依据的语言学习技巧，最初开发用于专业口译员的培训，并由多语言者Alexander Arguelles博士普及。这个方法简单而强大：您在听英语母语原声的同时立即大声重复——就像是一个延迟1-2秒紧跟说话者的影子。与被动听力或语法练习不同，跟读法强迫您的大脑和口腔肌肉同时处理并模仿真实的讲话模式。研究表明它能显着提高发音准确性，语调，节奏，连读，听力理解和口语流利度——使其成为雅思口语备考和真实英语交流最有效的方法之一。
