all the time 等于be always doing吗

all the time ==== always,如：
Jack makes mistakes in his math homework all the time.=== Jack always makes mistakes in his math homework.
再问： 那在句子中all the time 等于be always doing吗
再答： 不等，all the time 相当于副词结构，而be always doing 是动词+副词结构，应该是： He reads all the time. ==== He is always reading. 句中相等的是：read all the time === be always reading 希望对你有启发
