it作为代词 它的作用是指代名词，名词短语，或名词性从句

when后面的句子是名词性从句么？

那个~我能再问一个问题吗？~
A.In the late 1970’s, their growth rates for gross national product were among the highest in the world.
这个句子中说的他们的国民生产总值增长率是全世界最高~还是不一定是世界最高？

讨论下，我觉得A中的in 1825这个时间放置的位置也有问题，这个句子开头就用了when，那么是说a ton of wheat was being moved 在1825呢还是 the opening of the Erie Canal在1825呢，显然应该是后面这个意思，但是原句就会有歧义，用C的话这个问题就避免了。。当然it的用法也不对吧。。。

是的~有道理~其实关于这个时间的放法我也比较迷糊~放在句尾一半修饰动词吧？~然后放句子开头呢？···有没有专门讲时间放法的资料呢？~
