because —直接原因,非推断.语气最强.回答why的问题一定用because。

in order that …
“为了”; 用于正式文体中,所引从句可于主句前或后。
so that
a. 较常用,一般于主句后,so 有时可省;表示“以便...”
从句中通常要有情态动词, 以表示一种可能性或主观愿望:
b. 无情态动词则引导结果状语从句。
for fear that / in case / lest (以免)等。
e.g. We all get up early in order that we can start at seven.
e.g. I studied Italian so that I would be able to read Dante in the original.
e.g. She locked all the windows for fear that/in case/lest someone might break in.
注意:当从句与主句的主语一致时,可用
so as to do … 或 in order to do … 替换 so that...
e.g. He ran fast so that he might arrive there before
ten o’clock.
→
He ran fast so as to/in order to arrive there before ten o’clock.
连接词: 结果状语从句
so that 引导结果状语从句时通常不使用情态动词, 以表示客观事实,可翻译为 “结果””所以”

他们错过了公交车,结果上课迟到了。
Tom started out early so that he got a good seat.
汤姆动身早,所以他占了个好座位。
