87 Because of the noise outside, Nancy had great difficulty in focusing on the experiment. (集中注意力在实验上)
点评： have difficulty in doing sth.（in可以省略）这个搭配在2006年四级改革时的样卷中已经出过，当时是翻译“在找去博物馆的路方面有困难”。这次是重复出现，考生必须把历次真题及样卷的翻译看一看，写一写。

88 The manager never laughed; neither had she lost her temper. (她也从来没有发过脾气)
点评：考点是 部分倒装。部分倒装分两种情况，一种是否定词前置的（正如本题）；另一种是only前置的。

89 We look forward to being invited to attend the opening ceremony (被邀请出席开幕式)
点评：考点是被动语态的变化形式，look forward to的to是介词，所以后面用-ing结构。

90 It is suggested that the air conditioner (should) be installed by the window.(要安装在窗户旁)点评：考点是虚拟语气。Suggest等动词作主句谓语时，宾语从句往往用虚拟语气的表达，在表达过程中should可以省略。

91 The 16-year-old girl decided to travel abroad on her own despite her parents’ strong objection. (她父母的强烈反对)
点评：考点是重要介词的翻译方法。
