2
Our ocean is filled with a great diversity of marine life.
3
From microscopic plankton, cute clownfish,
4
chilled out sea turtles, to marine giants like sharks and whales.
5
But perhaps the cutest and one of the smartest marine animals of all are dolphins.
6
There are 38 species of dolphins, most of which live in the ocean, but a few species, like the Amazon River dolphin, live in freshwater.
7
Dolphins are mammals.
8
Like all mammals, they are warm blooded and females nurture young with milk.
9
You may recall that another characteristic of mammals is a body covered in fur or hair.
10
Although adult dolphins are hairless,
11
many newborn dolphins have a few whiskers around their snout when they are first born and lose them as they mature.
12
As mammals, dolphins also get the oxygen they need using lungs and must come to the surface regularly to take in air.
13
This is done through an opening on the top of their head, called a blowhole.
14
As vertebrates, dolphins have an internal skeleton of bone.
15
They have a well developed circulatory, respiratory and digestive system too.
16
Dolphins are well adapted to life in water.
17
They have sleek, streamlined bodies, which combined with fins and a powerful tail allow them to dart around effortlessly and with great speed.
18
All dolphins are active predators, feeding on a variety of fish, squid and crustaceans such as shrimps.
19
Many dolphins locate their prey using a special technique called echolocation.
20
They produce short pulses of sound that are reflected off prey and back to the dolphin.
21
Dolphins interpret reflected sound to determine the shape,
22
size, speed, distance and direction of travel of its unsuspecting prey, even at night or in murky water.
23
Another adaptation of many dolphins is a type of camouflage called countershading, whereby they are darker on the top and light on their underside.
24
This makes them difficult to spot from above and below.
25
Dolphins in groups are called pods.
26
A pod can consist of as few as five to ten dolphins or as many as a thousand.
27
Dolphins are capable of complex problem-solving and social interaction and communicate
28
and work together in diverse ways to group up and catch prey.
29
Living in pods helps to protect young as they mature.
30
So there you have it, all you need to know about the ocean's smartest and cutest animals.
31
If you have any questions, leave them in the comments below.

Thanks for learning!

Thank you.

القواعد في هذا الفيديو
أكثر التراكيب التي يستخدمها المتحدث، مع العبارات نفسها من الفيديو:
| التركيب | في الفيديو |
|---|---|
| المبني للمجهول be + اسم المفعول — التركيز على ما يحدث لا على من يفعله | can be found · is filled · is done |
| الوجوب: must / have to / need to قول إن أمرًا ما ضروري | must come · need to know |
نطق يحتاج إلى انتباه
- أصوات “sh” و“zh”: camouflage /ˈkæ.məˌflɑːʒ/, clownfish /ˈklaʊnˌfɪʃ/, crustacean /kɹʌsˈteɪʃən/, echolocation /ˌɛkoʊloʊˈkeɪʃən/, freshwater /ˈfɹɛʃˌwɔːtə(ɹ)/
- الكلمات الطويلة — انتبه لموضع النبر: circulatory /ˈsɝkjələˌtɔɹi/, echolocation /ˌɛkoʊloʊˈkeɪʃən/, effortlessly /ˈɛf.ɚt.ləs.li/, microscopic /ˌmaɪ.kɹəˈskɑ.pɪk/, respiratory /ɹɪˈspɪ.ɹət.ə.ɹi/
أصوات يجدها متحدثو العربية صعبة:
- /p/ — ليس /b/: انطقه مع نفخة هواء: prey /pɹeɪ/, pod /ˈpɑd/, microscopic /ˌmaɪ.kɹəˈskɑ.pɪk/, plankton /ˈplæŋ(k).tən/, predator /ˈpɹɛd.ə.tɚ/
- /v/ — ليس /f/: مع اهتزاز الأوتار الصوتية: digestive /daɪˈdʒɛstɪv/, vertebrate /ˈvɛɹ.tɪ.bɹeɪt/, diverse /daɪˈvɜːs/, diversity /daɪˈvɜː(ɹ)sɪti/
- تتابع الصوامت — لا تضف حركة بينها: prey /pɹeɪ/, blowhole /ˈbləʊhəʊl/, clownfish /ˈklaʊnˌfɪʃ/, crustacean /kɹʌsˈteɪʃən/, plankton /ˈplæŋ(k).tən/
كيف تتدرب بهذا الفيديو
- استمع إلى الفيديو كاملًا مرة واحدة دون أن تتكلم، ودوّن الكلمات التي لا تعرفها.
- ردّد جملة جملة بالسرعة العادية، وكرّر كل جملة حتى يتطابق إيقاعك مع المتحدث.
- سجّل صوتك وقارنه بالأصل، مع الانتباه إلى كلمات مثل dolphin, mammal, prey.
ما هي تقنية التظليل الصوتي؟
التظليل الصوتي (Shadowing) تقنية تعلم لغة مدعومة علمياً، طُورت أصلاً لتدريب المترجمين الفوريين المحترفين. الطريقة بسيطة لكنها قوية: تستمع لصوت إنجليزي أصلي وتكرره فوراً بصوت عالٍ — كظل يتبع المتحدث بتأخير 1-2 ثانية. تُظهر الأبحاث تحسناً كبيراً في دقة النطق والتنغيم والإيقاع وربط الأصوات والاستماع والطلاقة.
