In a previous design, the weight of the discus used in track competition is concentrated in a metal center, but now it is linked with lead around the perimeter, thereby improving stability in flight and resulting in longer throws.

想知道划线it 指的是weight么？要是weight我就觉得B没什么问题呀~困扰了很久~
还有说是指discus，说是用逻辑解释的~没搞懂是怎么个逻辑~重量被分布在周围不对么？非常痛苦~纠结了~

好像明白点了，可不可以这样理解，“is lined with lead”是衬铅的意思，所以指代的应该是discus铁饼，也就是铁饼被在周围衬铅来增加重量。所以it不能指代weight，weight是抽象名词，不能被衬铅

怎么我的版本 是  “it is lined with。。。。”

所以我觉得应该是 重量 线性分布在 周边，而不是 铁饼分布在周边啊？？

我已经困惑很久了，求解释

weight是个抽象名词~~~所以不能被设计撒

AnttiZhang

谢谢~我就这么记着吧~嘿嘿~可能是汉语也没太学好~我老觉得重量被设计成分布在周围也米什么问题~嘿嘿~

不过谢谢的呀~我就按你说的想啦~

这道题很多人问过，还是那句话~~~

weight 不能be  linked with lead。是铁饼被设计成重量分布在外围，而不是重量被设计成分布在外围
