to "fix the front door" versus "fix the front window". 可如果強調 "fix the front door" versus "fix the back door", 重音就應在 "front", 不在 "door" 了.
I guess the real question would be: if there is not context, just say "front door" by itself without 上下文, then, how to to say it? I just asked a native speaker, he said when he says "front door", he emphyasize neither word, the same 輕重.
