使用介词 from 的几个易错点
■自出事以来，他一直还在住院。
误：He has been in hospital since the accident.
[2]in hospital,hospital,相关知识点这里的school应看作不可数名词泛指学校的课程，即开学之意。要注意，有些活动场所当表达正在从事该种活动时不要加冠词，如：at table (吃饭)， When I came to Tom's home, they were at table. 还有： at desk (学习)，at work (工作) at school (上学)， in hospital (住医院) at
正：He has been in hospital since the accident.
[3]since,been,相关知识点It's/has been +一段时间+since从句 自从某时起做某件事情已经一段时间了。 该句型中since引导的时间状语从句常用一般过去时。例如： It's twenty years since he came here. 他来这里已经20年了。 It has been six years since he married Mary. 他和玛丽结婚已经六年了。考试用
析：from用于时间表示“从”，通常只表示时间的起点，要表示从某个时间持续到另一时间，通常用介词 since。注：在某些特殊情况下，from 也可能表示持续的时间，如：from...on (注意此处有 on)，from...to...(注意此处连用了介词 to)。另外 from childhood 同 since childhood 同义，如：We have been good friends since [from] childhood.(我们从童年时代起就是好朋友)。
[4]have been,have,相关知识点 have been to / have been in / have gone toⅠ. have been to … 表示：“曾经到过某处”但目前人未在那儿。如：① Where have you been? 你到哪儿去了？（现在已回来）I have been to Beijing. 我去北京了。（现不在北京）② I have never been there before,
■太阳从东方升起，从西方落下。
误：The sun rises from in the east and sets from the west.
正：The sun rises in the east and sets in the west.
析：汉语说太阳“从”东方升起，实际上是太阳升起“在”东方，故用介词 in。
■他躲在一棵树上，从那儿他可以看到远处的敌人。
误：He hid himself in a tree, from which he could see the enemy in the distance.
正：He hid himself in a tree, from where he could see the enemy in the distance.
析：关于此问题，首先要明确一点，from 是一个较特殊的介词，它后面不仅可以接名词或代词，而且可以接介词短语，如：He came out from behind the door.(他从门后出来)。上面一句的 from where＝from in the tree，即“从树里”。
