二十、It结构
一、强调句型 It is + 强调部分+that +其余部分
这个句型需要注意几点:强调部分+其余部分是一个完整的句子;强调部分可以强调主语、宾语和状语,不能强调谓语和定语;强调人使用who或者that, 其他的只能用that (即使是时间和地点),who 和that绝对不能省略如果原句是过去时态,强调句型使用it was.,例如: 原句: Ann bought these books last year. 强调宾语:It was these books that Ann bought last year. 强调状语:It was last year that Ann bought these books.
二、形式主语 It is + 名词/形容词+ to do/that 引导的句子 to do/that 引导的句子是真正的主语,it 是形式主语,这是为了避免头重脚轻。
例1:It is the interaction between people , rather than A B the events that occur in their lives , that are C the main focus of social psychology1. D 分析:Rather than …是插入语,主句是强调句型, it is …that, 主语是interaction, 所以是is
例2: ___an increasing international exchange of educational films. (A) It is (B) There is (C) Though there is (D) Although it is 分析:缺少主谓,选择B, it 用在句子的句首,只可能作强调句型或者形式主语。空格后是一个名词短语,只有B与之构成完整的句子。A语义不完整,C、D则使整个句子成了让步从句而缺主句,故都可排除。
