新概念lesson49的“so”
During the time she so gained my aunt's confidence,that she was put in charge of domestic staff.这里的so为什么能放在gained的前面,这也是so...that的用法么

Answer 1

是的、
这是牛津字典里的解释
so that; so...that
(a) with the aim that; in order that 为的是; 以便:
She worked hard so that everything would be ready by 6 o'clock.
她拼命干以便能到6点时把一切都准备好.
* He has so organized his life that his wife suspects nothing.
他把生活安排得井井有条, 为的是不让妻子有任何怀疑.
【这里so是副词的另外一个意思
in this or that way; thus 这样; 那样; 就这样:
Stand with your arms out, so. 两臂伸开站着, 就这样.
* So it was that he had his first sight of snow. 就那样, 他第一次见到了雪.
】
(b) with the result that; to the extent that 结果; 以致; 因此: Nothing more was heard from him so that we began to wonder if he was dead.
再也没听到他的消息, 因此我们有些怀疑他是否死了.
* He so adores his daughters that he keeps buying them expensive toys.
他非常疼爱女儿, 经常给她们买贵重的玩具.
