关于第一个问题同意你,area 和 size不能比较.. 这里比较的是land area ,not size 第二个问题: 摘自我总结的excel: some of them 和some of which所传达的意思也有所不同(OG12 #100也有同样的用法): SOME OF WHICH and SOME OF THEM serve different purposes. SOME OF WHICH serves to modify a NOUN and requires its own verb: The stars, SOME OF WHICH travel at tremendous speeds, are always in motion. The modifying clause here (some of which travel at tremendous speeds) tells us more about the STARS themselves. SOME OF THEM serves to modify a CLAUSE and is NOT provided its own verb: The stars are always in motion, SOME OF THEM at tremendous speeds. Here, the modifying phrase (some of them at tremendous speeds) tells us more not about the stars themselves but about HOW the stars are ALWAYS IN MOTION (they are in motion AT TREMENDOUS SPEEDS). -- by 会员 DUKB24 (2012/9/1 20:52:20)
