practical level是"实际水平"的意思么

问题描述

A number of economists predict that unemployment will drop to around its lowest practical level in the United States by the end of 2016. But others say employers remain cautious about taking on new workers, and wages are growing at a frustratingly slow pace.

practical level是实际水平的意思么？

老师答疑

童老师：

把这里的 practical level 理解成“实际水平”也可以，其实这个 practical 完全可以省略不用，加上去只是语意有所强调而已。英语中直接用lowest level 来表示“最低水平”是一个很常用的做法：

Inflation is down to its lowest level in three years. 通货膨胀率降到3 年来的最低点。

Unemployment is now at its lowest level for 15 years. 现在的失业人数处于15年来的最低值。

In May, the price of cocoa fell to its lowest level since 1975-76. 5 月份，可可的价格降到了 1975 至 1976 年以来的最低水平。

原文大意：一些经济学家预测，到2016年底，美国的失业率将下降到最底水平。但也有人说，雇主仍对雇用新员工持谨慎态度，而且员工薪资的增长也慢得令人沮丧。
