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.
56
You now have half a minute to check your answers.
57

- 時間推移攝影 (time-lapse photography): 記錄事物隨時間變化的影像技術。
- 樣本 (sample): 收集的沙子或其他物質的代表性部分。
- 記錄 (log): 精確記錄樣本的來源、時間和地點。
- 實驗室 (laboratory): 進行樣本分析和研究的地方。
練習建議
在進行英語口語練習時，建議您使用shadow speech技巧進行跟讀。觀看影片時，注意主播的語速和語調，並嘗試模仿。適應影片的快慢節奏可以幫助您提升英語口語練習能力。以下是一些具體的練習建議：
- 在播放影片時，暫停並反覆聆聽關鍵句子，嘗試準確模仿發音和語調，這是shadow speaks技術的核心。
- 使用shadow speak來跟讀每段介紹，集中注意力在語句的重音和停頓上。
- 可以選擇在舒適的環境中練習，加大語音練習的時長，逐步增加發音的流利度。
- 錄製自己的朗讀，回放並與原影片對比，找出差距並加以改正。
通過這些方法，您將能夠更有效地提高自己的英語口語能力和自信心。在進行練習時，保持積極的態度，並享受學習的過程！
影片中的語法
說話人最常用的結構，並附上影片中的原話：
| 結構 | 影片中的用法 |
|---|---|
| 被動語態 be + 過去分詞 — 強調發生了什麼，而不是誰做的 | being worn · is mounted · have been installed |
| 現在完成時 have/has + 過去分詞 — 過去發生但與現在仍有關聯的事 | has helped · have changed · have been installed |
什麼是跟讀法？
跟讀法 (Shadowing) 是一種有科學依據的語言學習技巧，最初開發用於專業口譯員的培訓，並由多語言者Alexander Arguelles博士普及。這個方法簡單而強大：您在聽英語母語原聲的同時立即大聲重複——就像是一個延遲1-2秒緊跟說話者的影子。與被動聽力或語法練習不同，跟讀法強迫您的大腦和口腔肌肉同時處理並模模擬實的講話模式。研究表明它能顯著提高發音準確性，語調，節奏，連讀，聽力理解和口語流利度——使其成為雅思口語備考和真實英語交流最有效的方法之一。
