句中的short of是干什么成分

The government now estimates emissions in 2030 will fall just short – by 56m tonnes – of meeting its target of a 26-28% cut compared to 2005 levels if Australia doesn’t deploy Kyoto credits to hit the target.

句中fall后面的short of是干什么成分？

类似的使用方法可以举几个例子吗

谢谢回答

fall short of 是 come short of 的变体，是系表结构。意为“不符合；不足；达不到目的；缺少”。

Anything she said would fall short of my expectations. 她说的任何话都不符合我的期望。
