我查了OG13,只有两句是A of B结构的:
7.The intricate structure of the compound insect eye, with its hundreds of miniature eyes called ommatidia, helps explain why scientists have assumed that it evolved independently of the vertebrate eye.
It指的是 the compound insect eye
51. A new study suggests that the conversational pace of everyday life may be so brisk that it hampers the ability of some children to distinguish discrete sounds and words and, as a result, to make sense of speech.
It指的是the conversational pace
似乎没有定论说it一定指代A or B,所以还是具体问题具体分析吧,理解为主。 |
