目标一: To read for and talk about how humans take inspiration from animals
Activity 1: Read the passage about biomimicry and answer the questions. Pay attention to the words and expressions in bold.
When solving a design problem, you can sometimes look to nature for a solution. One of the early examples is the study of birds to enable human flight. The Wright brothers, who succeeded in creating and flying the first aeroplane in 1903, got their inspiration from observing pigeons in flight. This approach, called biomimicry, studies and imitates nature's designs and processes to seek solutions to human problems. There are many types of biomimicry, among which the most common one is copying form and shape. By imitating the beak of a bird, for example, bullet trains can be made to run much faster and more quietly. Another type of biomimicry is taking inspiration from the abilities of animals. Inspired by dolphins, people have learnt how to send signals underwater, which is currently employed in tsunami early-warning systems.
