Large power shovels called excavators dig deep holes in the ground.
15
Some power shovels have huge buckets that can scoop a swimming pool-sized pile of dirt in one scoop.
16

34
We need big machines to get resources out.
35
Oil drilling rigs are set up to remove oil.
36
Large drills are used to get coal out of mines.
37

عن هذا الدرس

في هذا الدرس، سنتناول موضوع "الآلات الكبيرة" والتعرف على كيفية استخدام هذه الآلات في مختلف المجالات. سنستعرض كيف تقوم الآلات بنقل الأشياء من مكان إلى آخر وكيف تسهم في بناء المباني والطرق واستخراج الموارد من الأرض. من خلال مشاهدة الفيديو، ستتمكن من تحسين نطقك باللغة الإنجليزية من خلال ظاهرة shadow speech، مما يساعدك على استيعاب المصطلحات الجديدة المتعلقة بالآلات.

المفردات والعبارات الأساسية

  • جرافات (Bulldozers)
  • شاحنات Dump (Dump Trucks)
  • رصف الطرق (Paving)
  • أدوات حفر (Drills)
  • تجريف (Grading)
  • طائرات شحن (Cargo Planes)

نصائح للممارسة

للتحسين الفعّال لنطقك باللغة الإنجليزية، يمكنك استخدام طريقة التظليل في الإنجليزية. بعد مشاهدة الفيديو، حاول تكرار ما يقوله المتحدث بصورة دقيقة ومتماثلة. اجعل صوتك قريبًا من نبرة المتحدث وسرعته. إذا كانت سرعة الفيديو مناسبة لك، ابدأ بالتكرار الفوري. يمكنك استخدام تقنية shadowspeaks من خلال الاستماع بإمعان ثم تكرار الجمل وكأنك تتحدث مع المتحدث نفسه. لا تخف من تكرار العبارات أكثر من مرة حتى تصبح أمورك أسهل. هذه الطريقة ستساعدك في تعزيز ثقتك بنفسك أثناء التحدث وتحسين النطق بشكل تدريجي، مما يسهل عليك تعلم الإنجليزية مع يوتيوب.

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.
