新概念第4册14课,But suppose the earth could be covered with sensors spaced one foot apart,
rising at one-foot intervals all the way to the top of the atomosphere.
这样一来,我认为,but suppose,后面省略了that,所以后后面一直到apart是个从句,那也就是说逗号前面就一个but suppose,缺少主语怎么够得成句子?然后逗号后rising.是个现在分词,又不是句子.那这整个东西到底算什么,都没有句子啊!

【原句】But suppose the earth could be covered with sensors spaced one foot apart,rising at one-foot intervals all the way to the top of the atomosphere.
【翻译】但假设地球上可以布满传感器,每个相隔1英尺,并按1英尺的间隔从地面一直排列到大气层的顶端.
【具体分析解释】这句子是由suppose(假设)引导的一个条件状语从句构成,提出一个假定条件.在课文中此处是省略了主句了.在这个从句中,could表明使用的是虚拟语气.在suppose引导的条件状语从句中,既可以使用一般语气,也可以使用虚拟语气.当认为所假设的条件具有更多的不确定性时,通常可以使用虚拟语气.另外在be covered with(布满/覆盖着)中,可将covered视为一个形容词,表明状态.spaced one foot apart为过去分词短语,作定语,后置修饰sensors.rising at ... the atmosphere为现在分词短语,在句中作方式状语,说明could be covered with的方式.
