其实可以将其还原成陈述语序再分析
13为让步从句Though she was a girl ,she was very brave.As同样有尽管的意思,此处从句中的表语提前,要省略冠词a,构成倒装.
14.Susan knew little that ...主句中的宾语提前后面要加助动词,且为过去式did.
19.可参考 Here comes the bus.The bus comes here为完全倒装句 题目中 to recite the text是不定式做定语修饰 your turn.还原：(Your turn to recite the text )主(has come)谓( now)时间状语.
21 so+助动词+主语表.也是 例句：I was tired,so were they.so+主语+助动词表示 可不是嘛,是真的嘛eg It is going to be fine tomorrow.So it is.(明天天气会很好的,会是这样的）
23.我不确定应不应该当成语序讲.该句为虚拟语气,表示一种推测、假设,要是雨停的话农作物就能活下去.其他选项没有这个功能
不知道能不能帮上忙
