老外解析

    老外1

    老外原文：

    Either adjective is suitable, Long. 

I'd use "skilled" if I wanted to highlight the idea that she has received excellent training in designing web sites.

I might use "skillful" if I wanted to highlight the idea that she is designing in a skillful way.

    汉语意思：

    两个形容词都行的。如果我想强调她在网页设计方面受过良好的训练，我就会使用“skilled”。如果我想强调她构思的巧妙娴熟，我可能会使用“skillful”。
