Review: non-finite forms as subject, object and predicative
1
Look at the sentences from the reading passage and answer the questions.
a Today, architects continue to explore ways to capture the beauty of natural forms, ...
b ... it appears to float above the waterfront promenade and the water that surrounds it.
c Visitors are often amazed to find themselves in an urban building that so truly captures the beauty of natural forms.
d Creating buildings such as these enables us to live in closer harmony with our environment.
1 Look at the “to do” structures in sentences (a) and (b). Do they serve the same function in each sentence
2 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
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.
3 What is the function of the -ing form in sentence (d)
The -ing form is used as subject.
Now look for more sentences with these structures in the reading passage.
1. In fact, we are so used to them that we may even take them for granted without realising how much inspiration they have given us.
2. It is natural to think in this way,...
3. People whose interest is exploring the relationship...
4. To use biomimicry is to create structures...

Sample:
Learning from nature’s wisdom led farmers in Ancient China to create the 24 Solar Terms, which were based on observation of changes of seasons, astronomy and other natural phenomena. 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.
