도치구문어렵네요 해석좀 해주세요
scarcely had i started for schol when it rained heavily
=as soon as i started for school, it rained heavily
왜 이게 같은 문장이 되는지 해석과 함께 설명해주세요^^

1. (hardly, rarely ) had he seen me when he ran up to me.
답은 hardly

2. (scarcely , seldom) had he seen me before he ran up to me. 답은 scarcely
이 두문제도 왜 답이 이렇게 되는제 해석과 함께 설명해주세요. 부정문 도치라 모두다 쓸수있긴 한것 같은데 ... 해서을 통해서 답이 나오는 건가요
