1
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.

इस वीडियो के साथ बोलने का अभ्यास क्यों करें?
इस वीडियो में Dr. Rob Holman ने Argus प्रणाली के बारे में बताया है, जो समुद्री शोधकर्ताओं के लिए अत्यंत उपयोगी साबित हुई है। इस सामग्री का उपयोग करते हुए, आप न केवल सुनने की क्षमता को बढ़ा सकते हैं, बल्कि अपने बोलने के कौशल को भी निखार सकते हैं। जब आप इस वीडियो में बोले गए विचारों और अनुभवों को अपने शब्दों में दोहराते हैं, तो यह अंग्रेजी शैडोइंग की एक बेहतरीन प्रैक्टिस बन सकती है। इस प्रक्रिया से आपको ध्वनि और लहजे में सुधार करने का अवसर मिलता है, जिससे आप अंग्रेजी में अधिक आत्मविश्वास से बात कर सकते हैं।
संदर्भ में व्याकरण और अभिव्यक्तियाँ
वीडियो में कई महत्वपूर्ण भाषाई संरचनाएँ और अभिव्यक्तियाँ हैं, जो आपकी बोलने की क्षमता को सुधारने में मदद कर सकती हैं:
- “I would like to tell you” - यह निश्चितता और संकोच का अभिव्यक्त करता है, जो आपके वार्तालाप में शिष्टता जोड़ता है।
- “The system helps to solve the difficulties” - यहाँ 'helps to' का उपयोग किसी चीज की सहायता या लाभ होने को स्पष्ट करता है।
- “It is critical to the study of” - यह एक महत्वपूर्ण विपरीत बिंदु को प्रस्तुत करने का एक तरीका है।
- “You can use plastic bags” - यहाँ उच्चारण में स्पष्टता जरूरी है ताकि आप अपनी बात को स्पष्ठता से रख सकें।
इन संरचनाओं का उपयोग करते हुए, आप अपने विचारों को व्यक्त करने में और भी अधिक प्रभावी बन सकते हैं। वीडियो का अभ्यास करें और यूट्यूब से अंग्रेजी सीखें!
सामान्य उच्चारण में कठिनाइयाँ
वीडियो में कुछ शब्द और उच्चारण हैं जो विद्यार्थियों के लिए चुनौतीपूर्ण हो सकते हैं:
- “critical” - यहाँ उच्चारण में ध्यान दें कि पहले भाग पर जोर डालना महत्वपूर्ण है।
- “geologist” - इस शब्द का सही उच्चारण विद्यार्थियों द्वारा सही करना आवश्यक है, ताकि वह अपने वार्तालाप में विश्वसनीयता लाए।
- “installations” - यह शब्द थोड़ा लंबा है और इसमें बेहतर प्रवाह की आवश्यकता है।
इन उच्चारणों में सुधार करने के लिए, आप shadow speak का अभ्यास कर सकते हैं, जो आपके उच्चारण कौशल को बढ़ाने में मदद करेगा।
शैडोइंग तकनीक क्या है?
शैडोइंग (Shadowing) एक विज्ञान-समर्थित भाषा सीखने की तकनीक है जो मूल रूप से पेशेवर दुभाषिया प्रशिक्षण के लिए विकसित की गई थी। विधि सरल लेकिन शक्तिशाली है: आप मूल अंग्रेज़ी ऑडियो सुनते हैं और तुरंत इसे ज़ोर से दोहराते हैं — जैसे वक्ता की छाया 1-2 सेकंड की देरी से। शोध से पता चलता है कि यह उच्चारण सटीकता, स्वर, लय, जुड़ी हुई ध्वनियाँ, सुनने की समझ और बोलने की प्रवाहशीलता में काफ़ी सुधार करता है।
