the opposite wall/the house opposite
 【问】 《朗文英语正误词典》(PP.284—285)指出下列句子是错误的：
 ×The opposite woman was knitting a cardigan.
 对面那位妇女在编织毛线上衣。
 应改为：
 √The woman opposite was knitting a cardigan，并说明opposite在修饰名词时，位于该名词之后。但是我却遇到opposite位于名词之前的例句：
 He ran across the opposite house. (MED)
 他跑过对面的房子。
 这使我感到迷惑不解。查了许多辞书，也未查到答案。
 【答】 有些英语著作是这样来解释形容词opposite的这两种不同的位置的：
 当opposite表示“面对着说话人或被谈论的人”时，充当定语的opposite应当放在被修饰的名词之后，在其他场合，例如被修饰的名词是一对互相面对或者相反的事物中的一个，则应当放在被修饰的名词之前。请对比：
 1. She kept watch on the door opposite. (Galsworthy)
 她监视着对面的门。
 2. Sad were the lights in the houses opposite. (Mansfield)
 对面房子的灯光暗淡。
 3. The young man opposite had long since disappeared. (Mansfield)
 对面的年青人已经消失很长时间了。
 4. She hurried away in the opposite direction. (Dreiser)
 她急匆匆地向相反方向走去。
 5. Bill and Mary had opposite ideas about the weather.(AOT)
 比尔和玛丽对天气存在着相反的看法。
 6. I think the picture would look better on the opposite wall. (PEU)
 我认为，这张画要是挂在对面的墙上看起来会更好一些。
 7. There was a garden on the opposite side of the street.(Mansfield)
 街的对面有座花园。
 8. She works in the opposite room to this. (CGEL)
 她在这间房间对面的那个房间里工作。
