87. Those flowers looked as if they hadn't been watered for a long time(好长时间没有浇水了).
【点评】they即flowers做主语，用被动语态。一段时间应用完成时，looked过去式相比，后面应该过去完成时。
88. Fred bought a car last week. It is ￡1,000 cheaper than mine(比我的车便宜一千英镑).
【点评】简单的比较级，cheaper than。不需要重复car，直接用mine代替my car.
89. This TV program is quite boring. We might as well listen to the music(不妨听听音乐).
【点评】might as well“不妨”，原句中有might。listen to the music，听音乐。
90. He left his office in a hurry, with lights on and doors open(灯亮着，门开着).
【点评】with短语做伴随状语，逻辑主语和表语之间的系动词省略。
91.The famous novel is said to have been translated into multiple languages(已经被译成多种语言).
【点评】be said to后面跟动词原型，“已经被译”，用完成时被动语态have been translated，介词用into。
