Look at the “to do” structures in sentences (a) and (b). Do they serve the same function in each sentence? In sentence (c), is the -ed form used as an adjective or a past participle? Why does the author use the -ed form other than the -ing form? What is the function of the -ing form in sentence (d)? No, they don’t. “To explore” in sentence (a) serves as object and “to float” in sentence (b) serves as predicative. The -ed form is used as an adjective. The author wants to describe the visitors’ feeling, so the -ed form is used. The -ing form is used as subject. 3 Now look for more sentences with these structures in the reading passage.

Indicating changes in weather conditions, the 24 Solar Terms remain of particular importance to farmers for guiding their practices. The first term is known as “ Beginning of Spring”, and marks when days become longer and the temperature begins to increase. Nowadays, the 24 Solar Terms not only apply to farming, but also guide Chinese people in everyday life. So varied are the functions of the Solar Terms and their contributions to cultural identity, that in 2016, they were added to UNESCO’s List of Intangible Cultural Heritage. 19 Work in pairs.

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 got their inspiration from observing pigeons in flight, and in1903 successfully obtained a patent for their designs for the first aeroplane. 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, high speed trains such as China's CRH 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. Inspiration from animals 1 What are the types of biomimicry mentioned in the passage? What else do you know about them? One is copying form and shape. Another is taking inspiration from the abilities of animals. 2 What other examples of biomimicry can you think of? Share them with the class. Radar technology that mimics bat echolocation can be used to detect obstacles and track targets. Swimsuits that mimic the texture of shark skin are called "fast skins," which reduce current resistance and make swimming faster. Inspiration from animals Complete the information with proper words and expressions. taking inspiration from Copying observing inspired by seeking solutions to Inspiration from animals One of the outstanding features of traditional Chinese martial arts is the way they imitate animal movements. This came about because many Chinese martial artists admired the natural instincts, senses and fighting abilities that animals possess in order to survive in the wild. The first set of animal-imitating exercises came into being about 2,000years ago. It was called Wu Qin Xi, or Five-animal Exercises, created by Hua Tuo (ca145–208). As a physician during the Han Dynasty, Hua Tuo is often credited with being the first in China to use anesthesia during surgery. He was known as the best physician of his time, and was an expert in acupuncture. Read the passage and answer the questions.
