考研网

攻克英语长难句必须要熟练掌握各类句式结构的分析，再一一拆分解读，就自然而解了。新东方在线为大家梳理了一些常见的句式结构，帮助大家来加深理解：
   
    　　一、理论常识
        强调主要有两种形式：
        1. 强调谓语
    Eg1 ： I love you . —> I do love you . —> I did love you .
    Eg2 ： Cell phone / Internet / computer brings us convenience .
    —> Cell phone / Internet / computer does bring us convenience .
    2. 强调句式：It is / was + 被强调成分 +that / who + 句子其他成分。
    【步骤】
    a. 先写出正确的简单句、并列句或复合句，明确单句的各个成分。
    b. 在被强调成分(除谓语和补语外)两边添加it is / was 和that / who， 其他成分不变，必要时调整顺序。
    【强调句式特征】去掉it is / was ... that / who结构，整个句子无冗余或成分残缺。
    Eg1 ： My mother always encourages me not to lose heart when I have difficulties in study .
    —> It is my mother who / that always encourages me not to lose heart when I have difficulties in study .
    —> It is when I have difficulties in study that my mother always encourages me not to lose heart .
        二、真题举例
    Thus , in the American economic system it is the demand of individual consumers , coupled with the desire of businessmen to maximize profits and the desire of individuals to maximize their incomes that together determine what shall be produced and how resources are used to produce it .
    【重点词汇解析】couple with 与……相结合;maximize，v. 取……最大值、达到最大值
    【参考翻译】因此，在美国的经济体系中，个体消费者的需求与商人试图最大化其利润的欲望和个人想最大化其收入效用的欲望相结合，一起决定了什么应该被制造，以及资源如何被用来制造它们。
