VOA慢速英语:Why We Should Care About Trust, and Worry About a Lack of It

1.Professor Roth says poverty and unemployment do not lead to higher murder rates. Nor do stronger punishments and more police keep murder rates down.

Nor的用法

(1)传统规则要求nor 用于 neither 后面， 在这种表达中，否定放在第二个部分：他既不能也 （不用 or ) 不愿走。 Nor在当两个独立句子中的第二个也被否时被用， 在这种用法中，它也引起第二个句子主语和助动词的转变：
 
 He cannot find anyone now, nor does he expect to find anyone in the future; 
 现在他找不到任何人，以后也别梦想找到任何人 ；

 Jane will never compromise with Bill, nor will Bill compromise with Jane. 
 简决不会同比尔和解，而比尔也决不会同简和解。 

(2)然而当第一个否定词用not 或 never 表达， 且当第二个连结部分是动词短语时，nor 的用法通常可选择： 
 He will not permit the change, or (or nor ) even consider it. 
 他决不会容许改变，或者（或者用 nor ） 甚至考虑它。 

(3)当一个名词短语以形式no this or that 被 no，or 引入时比 nor 更常用：
 
 He has no experience or interest (less frequently nor interest ) in chemistry. 
 对于化学他既没经验也没兴趣（很少用 nor interest ) 。 

(4)Or在下面这种情况下比 nor 常用， 如一个名词短语、形容词短语或副词短语被not 引导时：
 
 He is not a philosopher or a statesman. 
 他既不是哲学家也不是政治家。

2.He looked at murder among unrelated adults and found four things that relate to homicide rates.

relate to与…相关,与…有联系,适应…

例句：Income tax rates are related to one's annual income.
      所得税税率与个人年收入的数额相关。

3.But Professor Roth says even the best political leaders cannot unite a country once a society's problems get out of control.

out of control不受控制

例句：The car ran down the hill out of control.
      汽车失去控制直往山下冲去。
