  1.       It would be completely irresponsible and unethical to use drugs on people that had not been thoroughly tested on animals.  
  该句用了虚拟语气，因为作者认为药品不经动物实验就用在人身上的可能性极小，因此可以看成是与现在事实相反的假设。注意本句没有用到虚拟条件句的形式，但完全可以改成虚拟条件句：It would be completely irresponsible and unethical to use drugs on people if they had not been thoroughly tested on animals.
  2.       The famous example of thalidomide is a case for more animal testing, not less.
  为了避免重复，less 后面省略了animal testing。 意为：“著名的萨立多胺的例子就说明应该对动物进行更多的试验，而不是更少.”
  case:  n.  理由，论据
  e.g. They presented a good case for changing the law.
  他们提出了一条很好的变更法律的理由
