谁帮忙分析下这个句子的句子结构

A jump in ballet during which the dancer crosses the legs a number of times, alternately back and forth.
空中交叉跳跃一种芭蕾舞动作，舞者在空中多次前后交叉双腿
during是个什么成分？谓语？

Answer 1

during 是介词, 后面的which引导了一个定语从句修饰ballet(芭蕾舞),which这里代替了ballet,所以during which就是“在芭蕾舞”的意思

这句话是把介词提前到关系代词which前的用法，和下面的例子是一样的：

The room [in which] he lived is next to mine. 他住的房间在我隔壁。

Answer 2

A jump in ballet during which the dancer crosses the legs a number of times
during是介词，which the dancer crosses the legs 是定语从句，修饰A jump ，in ballet 也是定语，也是修饰A jump ，during可以翻译成在...之间

Answer 3

连词，A jump in ballet during（the time ） which the dancer crosses the legs a number of time
这是一个从句，这句句子有问题哦！
