so that放在哪里

如题所述

so that可以放在句首也可以放在句中,意思不一样。
用法一、引导目的状语从句  
so that“以便,为了”,引导一个表示目的的状语从句,此时可与 in order that 换用;从句谓语中常用情态动词 may/might, can/could, should, would 等;主从句间连接紧凑,没有逗号相隔。
用法二、引导结果状语从句  
so that“因此,所以”,引导一个表示结果的状语从句,此时不能与 in order that 换用;从句中谓语根据需要使用相应的时态,主从句间可有逗号相隔。本文开头所列举例句中的 so that 就是这种用法。
用法三、辨别两种不同状语从句 
1) 根据句子结构辨别,从句谓语中含有情态动词 may/ might,can/ could, should, would 等,这时 so that 引导的是一个目的状语从句;从句前面有逗号和主句相隔,此时 so that 引导的是一个结果状语从句。  2) 根据主从句逻辑关系辨别  so that 引导目的状语从句,一般表示尚未完成的目的或意图,主句和从句之间是结果与目的关系;而 so that 引导的结果状语从句则是表示主句所导致的结果,主句和从句之间是原因与结果的关系。
用法四、同其它结构转换  
so that 引导目的状语从句时,可以与表目的的动词不定式 (not) to do …/so as(not)to do …/ in order (not) to do … 互换。但主从句主语须一致(句 ① ②),否则不能转换(句 ③)。  ① We went to the airport so that we might meet Professor Yang there.  → We went to the airport to meet Professor Yang there.  → We went to the airport in order to meet Professor Yang there.  → We went to the airport so as to meet Professor Yang there.  ② They had to walk a long way to/ in order to/ so as to fetch some firewood.  → They had to walk along way so that they might fetch some firewood.  ③ Mr.Cheng turned up the recorder so that every student in the classroom couldhear clearly. (主从句主语不一致)

so that 是“以便,为了”
eg. We study hard so that we can have a good future. 我们努力学习是为了我们能有一个好的未来

so……that 是“如此……以至于”
eg. The coffee is so hot that I can't drink now.
咖啡太热了以至于我现在不能喝。相当于too……to
The coffee is too hot to drink.
