The period between 1660 and 1785 was a time of amazing expansion for England — or for "Great Britain," as the nation came to be called after an Act of Union in 1707 joined Scotland to England and Wales. Britain became a world power, an empire on which the sun never set. But it also changed internally. The world seemed different in 1785. A sense of new, expanding possibilities — as well as modern problems — transformed the daily life of the British people, and offered them fresh ways of thinking about their relations to nature and to each other. Hence literature had to adapt to circumstances for which there was no precedent. The topics in this Restoration and Eighteenth Century section of Norton Topics Online review crucial departures from the past — alterations that have helped to shape our own world.
Ornithology is the study of birds. A scientist who studies birds is called an ornithologist. |
Birds are warm-blooded vertebrate animals that have wings, feathers, a beak, no teeth a skeleton in which many bones are fused together or are absent, and an extremely efficient,, one-way breathing system. Flying birds have strong, hollow bones and powerful flight muscles.
Most birds can fly. Birds have a very strong heart and an efficient way of breathing - these are necessary for birds to fly. Birds also use a lot of energy while flying and need to eat a lot of food to power their flight.
Not all flying animals are birds; and not all birds can fly. The ability to fly has developed independently many times throughout the history of the Earth. Bats (flying mammals), pterosaurs (flying reptiles from the time of the dinosaurs), and flying insects are not birds.

اهمیت فراگیری اصطلاحات
اصطلاحات (idioms) کلمات و عبارات ثابتی هستند کـه یـا از لحاظ گرامری غیرعادی هستند (مثل �Long time, no see!� و یا از این جهت که دارای معنیای هستند که نمیتواند از معانی کلمات تشکیل دهنده آن استخراج شود (مانند: It's raining cats and dogs!).
هر زبانی دارای اصطلاحات خاص خودش میباشد و اغلب فراگیری آنها برای زبانآموزها دشوار میباشد.
مثال:
معنی تحت اللفظی (نه یک اصطلاح):
- She broke the ice with a small hammer and dropped it into the blender.
- او با کمک یک چکش کوچک یخ را شکست و آن را داخل دستگاه مخلوط کن انداخت.
معنی اصطلاحی (یک اصطلاح):
- Before the conference began, the speaker broke the ice with a joke.
- قبل از آغاز کنفرانس، گوینده با یک لطیفه کارش را شروع کرد.
همانطور که میبینید، این عبارت (to break the ice) دو معنی متفاوت دارد که معنی تحتاللفظی آن �شکستن یخ� و معنی اصطلاحی آن �کاری را آغاز کردن� میباشد.
