1请问所有加1个 action noun 语法上正确吗? ex: student's assuming , 2还有请问 so that 和so as to 的具体区别和用法 3 OG 15 , many experts regarded.............., rather a sign of confidence by households that they could safely handle new debt. 请问为什么 by不能表述 household 的自信, 另外这里的 that 从句修饰household,感觉意思是对的啊,为什么OG上说 cause confusion 十分感谢。
