真诚的跪求懂英语的朋友们帮我解答下这几句英语

各位英语高手我现在真在学新概念英语44---48这几篇课文现在有几句需要麻烦大家帮忙解答下，大家也知道后面20课也的确很难！！！（2）the fact would have passed unnoticed.这句话passed是个动词 unnoticed我查了很多字典都是形容词，那有动词和形容词搭配的道理，听朋友说unnoticed修饰the fact 形容词修饰名词应该紧挨着啊！！！！（3）One of links in the chain that drives the wheels had snapped这句话had snappde应该修饰的是one of links可是one of links在这里做主语阿！按理说wheel前面也应该有one of links（5）there are only four ways you can deal with rubbish: dump it, burn it, turn it into something you can use again, attempt to produce less of it.这句话中of it前面没有名词？（6） you have the choice of very expensive organically-grown vegetables or a steady diet of pesticides这句话翻译为，那么你可以两者择一：或是选用价格昂贵、有机培植的蔬菜···为什么这句话没有把or a steady diet of pesticides这句话翻译出来，难道是二选一，所以往往翻译前半部分吗？？？（7）rated the highest form of noise pollution on a scale ranging from 1 to 7.这句话我查了下字典 on a scale 是各固定词组，这里的ranging修饰on a scale吧！但是不知道ranging是什么意思！

Answer 1

(6)的话，后一句相当于废话 强调的是要选有机蔬菜而不是充满杀虫剂的蔬菜。。
(2)我想知道语境
(3)这句没问题啊，that 后面一直到wheels是定语修饰chain，因此句子应该是One of links in the chainhad snapped
