参考答案：
87.Because of the noise outside, Nancy had great difficulty in focusing on her experiment (集中注意力在实验上)
88.The manager never laughed; neither did she lose temper (她也从来没有发过脾气)
89.We look forward to being invited to attend the opening ceremony(被邀请出席开幕式)
90.It is suggested that the air conditioner should be installed beside the window(要安装在窗户旁)
91.The 16-year-girl decided to travel abroad on her own despite her parents strong disagreement(她父母的强烈反对)
答案解析：
87题语法点为have difficulty in doing sth，另外focus on为四级高频词组需要牢记。
88题为neither 放在句首的倒装句，并且是部分倒装，把助动词did 提前，另外发脾气lose temper 为四级核心高频词组。
89题短语look forward to doing sth中的to为介词，后接的动词需要变成动名词，另外考察了被动的用法：be invited to do sth; 开幕式为the opening ceremony固定搭配。
90题为It is suggested that的虚拟语气，是四级重要考查语法点。that后面的句子结构为“主语+should+do sth”，此句中air conditioner“安装在窗户旁”暗含了被动含义，需要写成be installed。
91题考查despite后接名词，表让步含义。

参考答案
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，考前徐可风在文都的课堂上提到必需把历次真题及样卷的翻译看一看，写一写，就是因为徐可风已经意识到翻译题考点的高度重复性。
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。部分倒装徐可风在文都的课堂上强调了两种情况，一种是否定词前置的(正如本题)；另一种是only前置的。凡是在文都徐可风课堂上认真听课的考生，这道题如探囊取物。
89 We look forward tobeing 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。关于被动的翻译方法，请参考文都徐可风的相关课堂笔记。
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。关于虚拟语气的翻译方法，请参考文都徐可风的相关课堂笔记。
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。关于重要介词的翻译方法，请参考文都徐可风的相关课堂笔记。
综述：这次考试的翻译总体难度不大。上述是参考译文，不是唯一的正确答案。练习翻译是个很好的打基础的方法，它不仅让我们记住了单词的写法，同时更重要的是让我们掌握了单词的用法。在后面考六级或考研的文都学员，一定要充分记住徐可风的这个观点“翻译是最好的打基础方式”。

[page]2010年6月英语四级考试刚刚结束，同学们考得如何？。这里是沪江网校的Alex老师为大家提供的2010年6月英语四级翻译与解析。
87. Because of the noise outside, Nancy had great difficulty __________________________(集中注意力在实验上)。
88. The manager never laughed; neither ___________________(她也从来没有发过脾气)
89. We look forward to _____________________________(被邀请出席开幕式)
90. It is suggested that the air conditioner _____________________________(要安装在窗户旁)。
91. The 16-year-old girl decided to travel abroad on her own despite ______________________________(她父母的强烈反对)。
参考答案：
87. (in) concentrating on the experiment/ focusing her attention on the experiment。
88. did she become angry/did she lose her temper before。
89. being invited to attend the opening ceremony。
90. (should) be fixed/installed by the window
91. the strong opposition of her parents/ her parents’ strong opposition。
解析：
87. 本题考查两个短语的用法，一个是have difficulty (in) doing sth， 该短语中，后面的动词要用现在分词形式。第二个短语是集中注意力，与此对应的有多个短语，如：focus/fix one’s attention on, concentrate on。翻译时需和前面短语的用法结合起来，把动词变成ing形式。
88. 本题考查neither的倒装用法，以及发脾气这个短语，发脾气可以说become angry，也可以用lose one’s temper。
89. 本题考查look forward to的用法，后面要跟名词或者动词的ing形式，而且要注意后边是被邀请所以要用被动语态。
90. 本题考查It is suggested that结构中主语从句中要用虚拟语气的用法，即should + 动词原形，should可以省略。
91. 本题考查despite的用法，注意despite是介词，后边应该跟名词或者名词短语。
