Sentences (a) and (c) are from the reading passage. a ... what I say is that my pictures aren’t hurting anyone, so who cares? b “That my pictures aren’t hurting anyone is what I say, so who cares?” c It’s true that inner beauty is very important... d That inner beauty is very important is true... 1 What is the role of the words in bold in each sentence? 2 In sentence (a), what does “what” refer to? The role of the words in bold in each sentence is to act as the subject of the sentence. In sentence (a), “what” refers to the thing(s) that/which the speaker says. 3 What does “it” refer to in sentence (c)? 4 Why does the author choose to use sentences (a) and (c) instead of sentences (b) and (d)? In sentence (c), “it” refers to “that inner beauty is very important” The author chooses to use sentences (a) and (c) to place the focus on the end of the sentences, rather than the beginning.
