题目

Signers can face the same problems as other bilingual people.Their brains have to choose between two languages all the time.Take the words "paper" and "movie." Their spelling and meaning are not at all similar.But,as Professor Allen points out,the signs for them are.
最后一句,the signs for them are.的意思是这两个单词的手势是一样的 为什么这么翻译
就是FOR

答案

这里省略了,上一句说are not similar,下一句but 表示转折,这句的完整意思是the signs for them are silmiliar,与上一句相反.for表示对某人而言,即对他们来说,这两个单词的手势是相似的.
