从以上例证可以看出：in that 已经完全变成一个引导原因状语从句的连词，相当于for the reason that 或 because。那么用 for the reason that 或 because 去解释 “The problem lie in that the mist may become a thick fog.”中的 in that 显然是解释不通的，因为这句话的真实意思是“问题在于薄雾可能会变成大雾。” 即 in 和 that 不能连在一起构成表示 “because” 意义的连词；而应该是 lie 和 in 搭配在一起，意思是“在于”，但 that 又不能作一般意义上介词 in 的宾语，因此这句话是一个错误的表达，建议改为 The problem is that the mist may become a thick fog. 或 The problem lie in the fact that the mist may become a thick fog. 前者的正确性是众所周知的；后者也是英美语中的习惯表达形式。
