for two days 和for about two days有什么区别呢?
for about two days这是什么用法啊?为什么有for 和about两个介词呢?

for about two days 中的"about"是副词,修饰two days,意思是“大约,大概”.因此不用作介词.

for two days: 两天（确定的)
for about two days : 约两天的时间 （概数）可以这样用。

for two days 两天
for about two days 大约2天
for ...day(s) 用于指一件事持续的时间多长 是固定用法
例如：it rained for two days.
真正有实际意义的是那个about 在for about two days 里是大约的意思

about two day 大约两天
for + about two day （有/持续了）大约两天
for two days （有/持续了）两天

i will go abroad for two days, i will go abroad for about two days.如上面回答者那样,不要光用语法去学英语

一个确切，一个不确切，就像中文里说的大概一样
