句子要这么切割来理解,
the teacher would be at a loss “as to what to do” 老师对于该怎么处理正伤脑筋(没头绪)
in that 在此是俚语用法,连词功能,等同 because 或 inasmuch as 的意思
controlling the situation itself would be challenging enough 把局面稳住本身就已经有很大的难度了。
对于该怎么做,那位老师一片茫然,因为要控制局面都是极具挑战性的事
1. as to what to do 关于该怎么做
2. in that “因为”
请及时采纳,不懂继续问( 天天在线 )(*^__^*) 祝学习进步! 谢谢!
