inflation has been consistently lower than…中的lower

问题描述

This is no flash in the pan; over the past couple of years, inflation has been consistently lower than expected in Britain and America.

翻译：这并非昙花一现，在过去的几年里，英国和美国的通货膨胀率始终低于预期水平。

我的问题是，请问 lower 在句子里做什么成分，是表语还是宾语。谢谢。

老师答疑

蒋老师：

这个 lower 是表语，其前的 has been 是系动词 be 的完成时态，又如下面句子中的 lower 也是表语，而不是宾语：
