he will not do so for long,for mercifully the public have the good sense not to buy the inferior article more than once.

答

the article does what is claimed for it 这个商品能做到所宣称的
is claimed是谓语被动语态,for it是状语.还原成主动语态,就是：
the article does what they claimed for it
关系代词引导宾语从句时,不需要指代其它名词.如：
I like what you said.
You work with whoever is available.

2. What makes cyberspace so alluring is precisely the way in which it��s different from shopping malls, television, highways and other terrestrial jurisdictions.����˵whatָ��the way������ʲô������������ͱ���һ��ʽ�Ƿ�ʽ��������

   
   

1.比如这个That menans a higher proportion of what is in the sea is being caught.为何这个句子需要翻译出来what的指代的是前文的鱼？为何指代就不是自身的意思了？2.那这句为何用被动语态也翻译成所宣称的。。主动语态也翻译成所宣称。。，翻译时怎么没体现出被动的意思啊？是不是what从句里的被动语态只是说明和what的关系，翻译时不论是否被动，都一律译成所。。？3.for it做what的定语似乎也很顺，到底是定还是状？1. That means a higher proportion of what is in the sea is being caught.从语法上讲，这里的what并不指代任何东西。严格的翻译是：这意味着捕获了更大比例的海产品。海产品可以是鱼，也可以是虾、龙虾、贝壳。如果谁告诉你说what指代前面的鱼，那是错的。2. 中文的被动语态和英文不大一样，翻译时不能一一对应，要按意思来翻译。如：He was irritated by her manners.虽然直译应该是“他被她的举止所激怒”，但是正确的翻译是“她的举止激怒了他”。It is often said that ......人们常说……这是因为中文在这些情况下通常不用被动语态。尤其是第二个例子，绝对不能翻译为被动语态的“经常被提到”。3. for it修饰的是claim，不是what的定语，不然意思就不对了。
