as from和from区别具体如下:
1、意思区别
as from 英 [æz frɔm] 美 [æz frʌm]
adv.从…时起
例句:
Subs will be raised as from next year.
从明年开始将提高会费。
from 英 [frəm] 美 [frʌm]
prep.(表示时间)从…;(表示原因)因为;(表示来源)来自…;(表示分离)与…分离[隔开]
例句:
The guests watched as she fled from the room.
客人们看着她逃离了房间。
2、用法区别
as from 只用于表示时间或日期,即指事物开始的时间或日期。
例句:
As from today, you are in charge of the office.
从今天起,本办公室由你负责。
from 的用法则比较广,它除了表示时间或日期外,还可表示地点、方向、来源、出处等。
例句:
The train starts from London.
火车从伦敦开出。
as from 应该引导的是一个状语从句吧,from是个介词。
