核心问题
It doesn't seem that we can get our money back. 句中的否定是针对主句的, 还是针对 that 从句的?
词典解答
seem, appear, look as if(look like)等动词,与表示看法的动词(believe, think, imagine, suppose, fancy, reckon)一样,也允许否定的转移。
It doesn't seem that we can get our money back. It seems that we can't get our money back. 看来我们不能把我们的钱要回来了。
但是,有时候也可能不是否定的转移:
It just didn't seem that it would rain. 不像是要下雨(或好像不会下雨)。
