134　by day和by the day

① by day意為“在白天”，與 by night（在夜間）相對。

Most of us work by day，and only a few work by night. 我們大多數(shù)人上白班，只有少數(shù)人上夜班。

② by the day意為“按天計算”。同樣的表示法還有：by the week（按周），by the month（按月），by the year（按年）。

They are paid by the day while we are paid by the week. 他們的工資按天發(fā)，而我們的工資按周發(fā)。
