上面的内容摘自2022年高考英语天津卷(第二次)的单项填空。
查词典,record low 的意思是“有记录以来的最低点”“历史最低点”,此时的 low 是名词,不是形容词,而且是可数名词。这里为什么不用冠词呢?词典上好像都用的是 a record low。如:
Prices are at an all-time / record low. 价格已处于空前/有记录以来的最低点。
The currency slumped to a record low. 币值跌到了历史低点。
The temperature in Boston reached a record low last night. 昨晚波士顿的气温创下有记录以来的新低。
The nation’s infant mortality rate has reached a record low. 该国的婴儿死亡率已降至历史最低水平。
