外研选择性必修 第三册 Unit 5 Period 2 Grammar 1 2 To review the usage of non-finite forms as subject, object and predicative To use non-finite forms as subject, object and predicative 学习目标 目标一：To review the usage of non-finite forms as subject, object and predicative Activity 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? No, they don’t. “To explore” in sentence (a) serves as object and “to float” in sentence (b) serves as predicative. 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? 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. 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.It is natural to think in this way,...People whose interest is exploring the relationship...To use biomimicry is to create structures...
