【问】 (1) I’ve loved you as if you were my son.

(2) He looked as though he were，from the country.

as if与as though在意义和用法上有无区别?

【答】 许多语言学家都认为as if与as though在语义和用法上并没有什么区别。但是在口语中使用as if的情况较多。在A Comprehensive Grammar of the English Language中把as if和as though当作一个词条来处理。当然，从修辞上讲，存在着使用哪个形式更合适的问题。但是，这个问题已超出了我们的讨论范围。
