1.It was a good example of the scientific method working the way it is supposed to.
请问这个句子应该怎么划分语法结构,应该怎样理解呢?it is supposed to里的it指代的是什么呢?
答：It 是主语,was谓语,example宾语,of后面的一串都是介词短语.
完整的形式是：It was a good example of the scientific method （which is）working the way （that）it is supposed to.
定语从句的引导词被省略.
the way it is supposed to.的句型类似于：the food we eat=the food that we eat.我们吃的食物.
综上,该句意思是：这是一个很好的科学方法本来就应该的方式来工作的好例子.拗口哈,这样变一下：
此例子很好第诠释了科学方法本来就应该以这样的方式工作
但是该句具体意思还是要结合context综合理解,毕竟句不离段嘛!
2.Was this a failure of science,as some news reports trumpeted?
这个句子里是非限制性定于从句么?as起什么作用,做什么成分呢?
答,as 可单独使用,引导非限制性定语从句,作用相当于which.例如：
The elephant’s nose is like a snake,as anybody can see.
