跟在all后面的定冠词the为什么经常可省略?
Check all (the) measurements, please.
Of all (the) English writers then, Dickens had the most readers.
The reading-room is open to all (the) students of the English department,
He has been working all (the) day.
这个语法结构上ALL+名词和ALL the+名词都是OK,但是这个意思多数语境还是不一样的呀,不一样也是在于THE/THIS这个好像钟摆一样的手在指示。不否认某些语境两者类似,尤其后面接后置定语的时候,但多数时候意思有差别的呀。
