The guibiao on display in the museum is a part of an ancient observatory discovered at the Taosi ruins.
Archaeologists believe this is the earliest observatory known in China.
The most exciting part of the observatory are 13 rammed-earth columns arranged in a semicircular shape, Gao said.
本句话的主语究竟是part还是columns?
若主语是part,那么这里的主谓一致关系与表语一致了(好像语法书上见过)?
若主语是columns,那么这里将主语后置,是倒装,比如修辞性倒装?还是其他原因导致后置主语?
谢谢专家老师。
