3. Why do scientists often need to go to great lengths to effectively combine nature and innovation
Read paragraph 1 and 2 and answer the following questions.
1. What is the definition of bionics
2. When does the term “bionics” date from
Bionics is a science of taking inspiration from nature, which effectively combines nature and innovation to improve our lives.
It officially dates back to 1958, but the practice is centuries old, dating back as far as 2,500 years.
Because the process of the study involves four stages, which may have to be performed several times and it may take scientists years of trial and error to perfect the product.
◆ Present applications
Taking inspiration from plants
One idea grew from observing (1) _____________________________. The seeds grow at the “golden angle” of 137.5°, ensuring all of them receive sunlight. (2) __________________________, the sunflower’s face also follows the sun’s path.
Solar mirrors are arranged to (3) ________________________ and positioned at the same “golden angle”. The mirrors are also programmed to follow the sun.

Bionics is a science of taking inspiration from nature, which effectively combines nature and innovation to improve our lives. Over billions of years, humans have been inspired to imitate nature’s forms and functions owing to our curiosity. Though the process is not so simple, scientists have succeeded in studying and taking advantage of nature to develop materials and technologies. It is certain that our future will see many more fascinating partnerships between the natural world and the technological one because of advancements in bionics. Therefore, nature not only provides our lives with a scenic backdrop, it could also prove to be our greatest teacher.
