It is difficult to answer the question这句对吗?

这两句表达都对,但意思还是有微妙的区别,给你分析一下：
*It is difficult to answer the question 意思是"回答这个问题很困难",可能是问题本身困难,也可能是别的原因使问题难回答(如当事人不便回答).这是一个"it's"强调句型,强调difficult.正常语序是:to(I) answer the question is difficult.difficult在这里做表语.
*It is a difficult question to answer.意思是"这是一个很困难(回答)的问题".侧重问题本身困难.本句强调"a difficult question".
请注意这两种表达意义的不同,往往一个词位置的差异会造成语境上的很大差别,不能小看哦.
