选做题目：
★It is obligatory that every young man serves in the armed forces.
必做答案：
1.应该将am living改为were living.该题考察wish+that从句的虚拟表达法。Sometimes是一个频率副词，表示现实里经常性的动作，显然这里需要的动词虚拟式为过去时形式。
2.应该将could not be改为could not have been。该题考察非真实条件句虚拟语气的用法。根据从句可知此处是与过去事实相反的虚拟，且solve与many problems之间为被动关系，因而要用could not have been solved的表达形式。
选做答案：应该将serves改为serve。该题考察obligatory之类的形容词引导主语从句，从句中要使用虚拟语气，从句中动词形式为should+动词原形，should可以省略。

1.【解析】该题考察the more….the more…结构的意义和构成倒装语序的用法。该句为复合句。The more…the more…引出比较状语从句，后面要用倒装语序，表示“越…就越…”
【句意】法制越完善，社会在发现、控制和惩罚暴力行为中承担的责任就越大。
2.【解析】该题考察倒装语序的使用。该句为复合句。全句的框架是the notion that….is at the top of the list。该句是一个全部倒装句，因为主语太长，所以表语提前避免头重脚轻。That 引导同位语从句，解释说明notion。三个并列的不定式短语都作定语，修饰ability。
【句意】在榜单上列头名的说法是：智慧需根据你解决复杂问题的能力、读写算的水平及快速解抽象方程式的能力来衡量。
★选做:
【妙译】然而，自我实现对道德来讲是重要的，因为不发挥作用的公民，无论他们多么有道德，也不会履行道德所赋予他们的义务。
【点拨】本句为复合句。主句的主谓结构为“self-fulfillment is important”;在原因状语从句中的主语“unfulfilled citizens”和谓语“can not perform”之间插入了让步状语“no matter how virtuous”,在让步状语中省略了they are.
